    VEHICLE LIGHT The present invention relates to a vehicle light configured to reflect and control the light emitted by first and second light emitting elements by means of a reflector.
    In the prior art, a vehicle light is known which is configured to reflect and control the light emitted by a first light emitting element which is lit in a first lighting mode and the light emitted by a second light emitting element which is switched on in a second lighting mode by means of a reflector.
    Japanese patent publication subject to public inspection No. 2014-170629 describes a reflector in a vehicle light in which a first reflector configured to reflect and control the light emitted by a first light emitting element and a second reflector configured to reflect and control light emitted from a second light emitting element are arranged such that the second reflector is placed on the rear side of the first reflector.
    In the vehicle fire described in the Japanese patent publication subject to public inspection No. 2014-170629, the first reflector is formed from a material allowing light to pass through, and a zone reflecting light and an area leaving passing light are formed on the front surface of the first reflector. In addition, the light reflected from the second reflector is configured to pass the first reflector through the area allowing the light to pass.
    In the vehicle fire described in the Japanese patent publication subject to public inspection No. 2014-170629, a partial area of the first reflector may be caused to emit light in any of the first and second lighting modes, but the first reflector may not emit light over a wide range.
    The present invention was made due to the circumstances described above and provides a vehicle light which can cause a reflector to emit light in a second lighting mode over a wide range. The vehicle light is configured to reflect and control light emitted from a first light emitting element to be turned on in a first lighting mode and light emitted from a second light emitting element to be turned on in a second lighting mode.
    The present invention achieves the aim described above by studying a method of incidence of the light emitted by each of the first and second light emitting elements on a reflector.
    That is, the vehicle light according to the present invention comprises: a first light-emitting element which is lit in a first lighting mode; a second light emitting element which is turned on in a second lighting mode; and a reflector which reflects and controls the lights emitted from the first and second light emitting elements. The reflector includes first and second reflective surfaces. The light emitted from the first light emitting element is configured to be incident on the first reflecting surface and not on the second reflecting surface, and the light emitted by the second light emitting element is configured to be incident on the first and second reflective surfaces.
    [0009] The specific lighting modes of the “first lighting mode” and “second lighting mode” are not particularly limited.
    The types of “first and second light emitting elements” are not particularly limited, and light emitting diodes or laser diodes can for example be adopted.
    A position relationship between the "first and second light emitting elements" and a position relationship between the "first and second reflective surfaces" are not particularly limited. "The light emitted by the first light emitting element is configured to be incident on the first reflecting surface and not on the second reflecting surface" described above not only includes an aspect in which the light emitted by the first light emitting element is not at all incident on the second reflecting surface, but also an aspect in which the light emitted by the first light emitting element is incident on the second reflecting surface as light n not affecting the function of a light in the first lighting mode.
    The vehicle light according to the present invention is configured such that the vehicle light comprises first and second reflecting surfaces as reflectors which reflect and control the light emitted by the first and second light emitting elements and that the light emitted by the first light emitting element to be turned on in the first lighting mode is incident on the first reflecting surface and not on the second reflecting surface, and the light emitted by the second emitting element of light to be turned on in the second lighting mode is incident on the first and second reflective surfaces. The following effects can thus be obtained.
    That is, the first reflecting surface on which the light emitted by the first light emitting element is incident can preferably be used as a reflecting area configured to form a first light distribution configuration. in the first lighting mode, and the first and second reflective surfaces on which the light emitted from the second light emitting element is incident can be used as a reflective area configured to form a second light distribution configuration in the second lighting mode.
    At this time, since the light emitted by the first light emitting element is not incident on the second reflecting surface, the second reflecting surface can be used as a dedicated reflecting area which forms a second configuration light distribution.
    [0016] Thus, once the first and second light distribution configurations can be effectively formed, the first and second reflective surfaces can be caused to emit light in the second lighting mode.
    According to the present invention, in a vehicle light configured to reflect and control the light emitted by a first light emitting element to be turned on in a first lighting mode and the light emitted by a second element emitting light to be turned on in a second lighting mode using a reflector, the reflector can be caused to emit light over a wide range in the second lighting mode.
    In some embodiments, the first lighting mode is a headlight lighting mode and the second lighting mode is a daytime running light lighting mode. Thus, the following effects can be obtained.
    That is, in the lighthouse lighting mode, a light distribution configuration for a lighthouse (for example a low beam light distribution configuration or a light distribution configuration main beam) may be formed by the light reflected from the first reflecting surface. In the daytime running light lighting mode, a light distribution pattern for a daytime running light can be formed by the light reflected from the first and second reflecting surfaces. At this time, since the reflector emits light over a wide range, it is easy to identify that the fire emits light when it is seen from the outside even in daylight.
    In some embodiments, the vehicle light includes a light mask element provided so that the light emitted by the first light emitting element is not incident on the second reflecting surface. It is thus possible to reliably prevent the light emitted by the first light emitting element from being incident on the second reflecting surface with a simple configuration.
    It is also possible to prevent the light emitted by the first light emitting element from being incident on the second reflecting surface by studying, for example, the arrangement of the first and second light emitting elements or the arrangement of the first and second reflecting surfaces instead of adopting a configuration comprising the light mask element described above.
    In certain embodiments, the vehicle light comprises a secondary reflector which reflects part of the lights emitted by the second light-emitting element and reflected on the second reflecting surface towards the first reflecting surface. It therefore becomes possible to easily establish the direction of the lights reflected by the first reflecting surface in a desired direction. Thus, it is possible for the first reflecting surface to emit stronger light in the lighting mode in which the second light emitting element is turned on.
    In some embodiments, the first and second light emitting elements are mounted on a common substrate. Thus, the number of components can be reduced and the configuration of the light can be simplified.
    In some embodiments, the vehicle light includes a secondary light source configured to be lit in the second lighting mode and to cause light to be incident on the first reflecting surface. Thus, it is possible to cause the first reflecting surface to emit stronger light in the lighting mode in which the second light emitting element is turned on. The particular configuration of the term "secondary light source" is not particularly limited. In some embodiments, in the second lighting mode, the first light emitting element is configured to be turned on in a weakened state greater than when the first light emitting element is turned on in the first lighting mode. Thus, the reflector can be caused to emit light over a wide range in the second lighting mode without using a new element.

    Example embodiments of the present invention will be described below with reference to the accompanying drawings.
    Figure 1 is a partially sectional front view of a vehicle light 10 according to an exemplary embodiment of the present invention. In addition, Figure 2 is a sectional view along line II-II of Figure 1, and Figure 3 is a sectional view along line III-III of Figure 1.
    As illustrated in these figures, the vehicle light 10 according to the exemplary embodiment of the present invention is a light arranged at the front end of a vehicle and functions both as a headlight and a daytime running light.
    The vehicle light 10 has a configuration in which four 20Ά and 20B fire units are inserted in parallel in a vehicle width direction in a fire chamber formed by a fire body 12 and a transparent translucent cover 14 fixed on the front end opening of the lamp body 12.
    In addition, in this vehicle light 10, two light units 20B are used in a low beam illumination mode in a headlight lighting mode, two light units 20A are used additionally in a high beam illumination mode in a headlight lighting mode, and four light units 20A and 20B can be used in a daytime running light lighting mode.
    The two 20A light units for the main beam illumination have the same configurations. That is, each of the light units 20A includes first and second light emitting elements 22A and 24A and a reflector 30A which reflects forward the light emitted by the first and second emitting elements 22A and 24A light.
    At the same time, the two light units 20B for the illumination of the dipped beam have the same configurations. That is, each of the light units 20B includes first and second light emitting elements 22B and 24B and a reflector 30B which reflects forward the light emitted by the first and second emitting elements 22B and 24B light.
    The first and second light emitting elements 22A and 24A of each light unit 20A are arranged downward at intervals in the longitudinal direction. In addition, the first and second light emitting elements 22B and 24B of each light unit 20B are arranged downward at intervals in the longitudinal direction. The first and second light emitting elements 22A and 24A and the first and second light emitting elements 22B and 24B are each configured as white light emitting diodes having a rectangular light emitting surface (for example square).
    The first light emitting element 22A of each light unit 20A is configured to be lit in ίο the high beam illumination mode in the headlight lighting mode, and the first emitting element 22B of each 20B light unit is configured to be on in the low beam illumination mode and the high beam illumination mode in the headlight lighting mode.
    At the same time, the second light emitting element 24A of each light unit 20A and the second light emitting element 24B of each light unit 20B are configured to be lit in the lighting mode daytime running light.
    The first and second light emitting elements 22A and 24A of each light unit 20A and the first and second light emitting elements 22B and 24B of each light unit 20B are mounted on the lower surface of a common substrate 40 arranged horizontally so as to extend in the vehicle width direction. The substrate 40 is supported on a support member 50 on the lower surface thereof.
    The support member 50 is supported by the fire body 12 in a state of arrangement to extend in the vehicle width direction.
    In the support element 50, a part which is located on the front side of the first light emitting elements 22A and 22B of each of the light units 20A and 20B is configured as a thin-walled part 52, a part which is located on the rear side of the second light emitting elements 24A and 24B of each of the light units 20A and 20B is configured as a thick-walled part 54, and a part which is located between the first light elements the light emission 22A and 22B and the second light emission elements 24A and 24B is configured as a light mask part 56 (which will be described later).
    The support member 50 has an upper surface extending along the horizontal plane and a front end portion and left and right end portions extending upward from the upper surface of the support element 50 so as to cover the substrate
    40.
    The reflector 30A of each light unit 20A and the reflector 30B of each fire unit 20B are formed in one piece as a continuous body of reflector 30. [0052] The continuous body of reflector 30 is supported by the thick-walled portion 54 of the support member 50 at a flange portion 30a formed in the upper end portion thereof.
    Next, the particular configuration of the reflector 30A of each light unit 20A and of the reflector 30B of each light unit 20B will be described.
    [0054;
    The particular configuration of the reflector 30A will first be described.
    The reflector 30A includes first and second reflecting surfaces 30Aal and 30Aa2. The first and second reflective surfaces 30Aal and 30Aa2 have a rectangular exterior shape as a whole when viewed from the front of the light and are formed in two upper and lower stages in the vertical direction so that the first reflective surface 30Aal is positioned on the rear side of the second reflecting surface 30Aa2. At this time, the second reflecting surface 30Aa2 is formed to have a smaller vertical width than the first reflecting surface 30Aal (more specifically a vertical width of 1/3 or less (for example a vertical width of about 1/4 )).
    The first reflecting surface 30Aal is arranged so as to be positioned under the first light-emitting element 22A. The first reflecting surface 30Aal comprises a plurality of reflecting elements 30Asl and reflects the light emitted by the first light emitting element 22A as light slightly scattered in the vertical direction towards the front of the vehicle and also as highly scattered light to both left and right sides. The second reflecting surface 30Aa2 is arranged so as to be positioned under and near the part slightly behind the second light emitting element 24A. The second reflecting surface 30Aa2 comprises a plurality of reflecting elements 30As2 and reflects the light emitted by the second light-emitting element 24A as light slightly scattered in the vertical direction towards the front of the vehicle and also as highly scattered light to both left and right sides.
    In each light unit 20A, the light emitted by the first light emitting element 22A towards the second reflecting surface 30Aa2 is masked by the light mask part 56 of the support element 50 so that the light is not incident on the second reflecting surface 30Aa2.
    At the same time, the light emitted by the second light emitting element 24A towards the first reflecting surface 30Aal is not masked by the light mask part 56 of the support element 50 and is incident on the first reflecting surface 30Aal. At this time, since the second light emitting element 24A is positioned behind the first light emitting element 22A, the light emitted by the second light emitting element 24A is reflected as light which is slightly down on the first reflective surface 30Aal.
    first 30Ba2 have the particular configuration of the reflector 30B will then be described.
    The reflector 30B comprises first and second reflecting surfaces 30Bal and 30Ba2. The second and 30Bal reflective surfaces and the whole rectangular outer shape when viewed from the front of the light and are formed in two upper and lower stages in the vertical direction so that the first 30Bal reflective surface is positioned on the rear side of the second reflecting surface 30Ba2. At this time, the second reflecting surface 30Ba2 is formed to have a smaller vertical width than the first reflecting surface 30Bal (more specifically a vertical width of 1/3 or less (for example a vertical width of about 1/4 )).
    The first reflecting surface 30Bal is arranged so as to be positioned under the first light-emitting element 22B. The first reflective surface 30Bal comprises a plurality of reflective elements 30Bsl and reflects the light emitted by the first light emitting element 22B as light which is diffused slightly downwards towards the front of the vehicle and also as light which is strongly diffused towards both left and right sides. The second reflecting surface 30Ba2 is arranged so as to be positioned under and near the part slightly behind the second light emitting element 24B. The second reflecting surface 30Ba2 comprises a plurality of reflecting elements 30Bs2 and reflects the light emitted by the second light emitting element 24B as light scattered slightly in the vertical direction towards the front of the vehicle and also as highly scattered light to both left and right sides. At this time, the second reflecting surface 30Ba2 is formed such that the upper region thereof is largely curved in the vertical section, and as a result, the light reflected from the lower region is reflected with a large angle in an oblique upward direction. In each light unit 20B, the light emitted by the first light emitting element 22B towards the second reflecting surface 30Ba2 is masked by the light mask part 56 of the support element 50 so that the light is not incident on the second reflecting surface 30Ba2.
    At the same time, the light emitted by the second light emitting element 24B towards the first reflecting surface 30Bal is not masked by the light mask part 56 of the support element 50 and is incident on the first reflective surface 30Bal. At this time, since the second light emitting element 24B is positioned behind the first light emitting element 22B, the light emitted by the second light emitting element 24B is reflected as light which is slightly down on the first reflective surface 30Bal. However, the downward angle of the reflected light becomes larger than the downward angle of the light which is emitted from the second light emitting element 24A and reflected on the first reflecting surface 30Aal in the unit of fire 20A. This is due to the fact that the first reflecting surface 30Bal is configured to reflect the light emitted by the first light emitting element 22B as light slightly down towards the front of the vehicle.
    In the thin-walled portion 52 of the support member 50, a secondary reflector 58 is integrally formed with the thin-walled portion 52 at a portion where each light unit 20B is positioned .
    The secondary reflector 58 comprises a plurality of reflective elements 58s which project from the lower surface of the thin-walled part 52 in the shape of a sawtooth. In the plurality of reflecting elements 58s, the secondary reflector 52 reflects the light reflected in the upward oblique direction from the lower region of the second reflecting surface 30Ba2 to the first reflecting surface 30Bal.
    At this time, since the secondary reflector 58 is positioned in front of the first light-emitting element 22B, the light reflected by the secondary reflector, which is incident on the first reflecting surface 30Bal, is reflected as light oblique upwards.
    Likewise, in FIGS. 2 and 3, the rays of light used in a headlight lighting mode are indicated by solid lines, and the rays of light used in a driving light lighting mode of day are indicated by dotted lines. The same applies to different modifications to be described later.
    FIGS. 4A to 4C are perspective views illustrating a light distribution configuration which is formed on a virtual vertical screen arranged in front of the vehicle light 10 by the light illuminated forwards from the vehicle light 10.
    The light distribution configuration illustrated in FIG. 4A is a low beam light distribution configuration PL, the light distribution configuration illustrated in FIG. 4B is a high beam light distribution configuration PH , and the light distribution configuration illustrated in Fig. 4C is a daytime running light distribution light configuration PD.
    The low beam light distribution configuration PL illustrated in FIG. 4A is formed as a light distribution configuration obtained by combining two light distribution configurations which are formed by the lights reflected by the reflector 30B when the first light emitting elements 22B in two light units 20B are lit.
    The low beam light distribution configuration PL is a low beam light distribution configuration of the light distribution on the left side, and has a cut-off line CL with a significant left and right difference on the upper edge of it.
    The PH high beam light distribution configuration illustrated in FIG. 4B is formed as a light distribution configuration obtained by combining the low beam light distribution configuration PL and an additional light distribution configuration PA.
    The additional light distribution configuration PA is formed as a light distribution configuration obtained by combining two light distribution configurations which are formed by the lights reflected by the reflector 30A when the first light emitting elements 22A in two 20A fire units are lit.
    The additional light distribution configuration PA is a horizontally long light distribution configuration which spreads on both left and right sides around HV, which is a point of disappearance in the front direction of the fire, and is formed so that the cut-off line CL extends vertically.
    The daytime running light distribution pattern PD illustrated in FIG. 4 (c) is formed as a light distribution configuration obtained by combining four light distribution configurations which are formed by the lights reflected by the reflectors 30A and 30B when the second light emitting elements 24A and 24B in four light units 20A and 20B are on.
    The PD daytime running light distribution pattern is formed as a horizontally long light distribution pattern which spans both left and right around H-V.
    The operational effects of the present exemplary embodiment will then be described.
    The vehicle light 10 according to the present exemplary embodiment is configured such that the light unit 20A for high beam illumination comprises first and second reflecting surfaces 30Aal and 30Aa2 as reflectors 30A which reflect and control the lights emitted by the first and second light emitting elements 22A and 24A, as the light emitted by the first light emitting element 22A to be turned on in the headlight lighting mode (first mode d lighting) is incident on the first reflecting surface 30Aal and not on the second reflecting surface 30Aa2, and that the light emitted by the second light emitting element 24A has to be turned on in the daytime running light lighting mode (second lighting mode) is incident on the first and second reflecting surfaces 30Aal and
    30Aa2. The following operational effects can thus be obtained.
    [0081;
    That is, once the first reflective surface 30Aal on which the light emitted by the first light emitting element 22A is incident is preferably used as a reflective area configured to form the distribution pattern of additional light PA for the high beam light distribution configuration PH (light distribution configuration to be formed in a first lighting mode), the first and second reflecting surfaces 30Aal and 30Aa2 on which the light emitted by the second light emitting element 24A is incident can be used as a reflective area configured to form a daytime running light distribution pattern PD (light distribution pattern to be formed in a second lighting mode).
    At this time, since the light emitted by the first light emitting element 22A is not incident on the second reflecting surface 22Aa2, the second reflecting surface 30Aa2 can be used as a dedicated reflecting area configured for form a PD day shift distribution configuration.
    Thus, once the traffic light of the PH route configuration and the traffic light distribution light of the PD daytime running light distribution light can be effectively formed, the first and second reflective surfaces 30Aal and 30Aa2 may be caused to emit light in the daytime running light mode.
    In addition, since the vehicle light 10 according to the present example embodiment has the same configuration as the light unit 20A for high beam illumination even for the light unit 20B for illumination headlamp, once the low beam light distribution pattern PL and the daytime running light distribution pattern PD can be effectively formed, the first and second reflecting surfaces 30Aal and 30Aa2 can be brought emitting light in the daytime running light mode.
    According to the present exemplary embodiment, in the vehicle light 10 configured to reflect and control the lights emitted by the first light emitting elements 22A and 22B to be turned on in the headlight lighting mode and the lights emitted by the second light emitting elements 24A and 24B having to be turned on in the daytime running light illumination mode by the reflectors 30A and 30B, the reflectors 30A and 30B can be caused to emit light over a wide range in daytime running light mode. Thus, it is possible to easily identify that the vehicle light 10 emits light when the vehicle light 10 is seen from the outside even in daylight.
    In addition, according to the present exemplary embodiment, since the light mask part 56 is provided on the support element 50 as a light mask element configured to prevent the lights emitted by them. first light emitting elements 22A and 22B to be incident on the second reflecting surfaces 30Aa2 and 30Ba2, it is possible to reliably prevent the lights emitted by the first light emitting elements 22A and 22B from being incident on the second reflecting surfaces 30Aa2 and 30Ba2 with a simple configuration.
    In addition, in the vehicle light 10 according to the present exemplary embodiment, the light unit 20B for the illumination of the dipped beam comprises a secondary reflector 58 which reflects part of the lights emitted by the second light emitting element 24B and reflected on the second reflecting surface 30Ba2 towards the first reflecting surface 30Bal, it becomes possible to easily establish the direction of the lights reflected by the first reflecting surface 30Bal towards a desired direction. Thus, it is possible to cause the first reflecting surface 30Bal to emit stronger light in the daytime running light illumination mode.
    At this time, the downward angle of the light which is emitted by the first light emitting element 22B and reflected on the first reflecting surface 30Bal in the light unit 20B for illumination of dipped beam headlight becomes larger than the downward angle of the light which is emitted from the first light emitting element 22A and reflected on the first reflecting surface 30Aal in the light unit 20A for illumination of road. Thus, by providing the secondary reflector 58 described above, it is particularly relevant to increase the light reflected upwards by the first reflecting surface 30Bal in the daytime running light illumination mode. In addition, according to the present exemplary embodiment, since the first and second light-emitting elements 22A, 22B, 24A and 24B of each of the fire units 20A and 20B are mounted on a common substrate 40 , the number of components can be reduced and the configuration of the vehicle light 10 can be simplified. According to the example embodiment described above, the light mask element is configured by the light mask part 56 of the support element 50. However, the light mask element can be configured as an independent element of the support element 50.
    According to the example embodiment described above, the secondary reflector 58 comprises a plurality of reflective elements 58s and is formed integrally with the thin-walled part 52 of the support element 50 However, it is also possible to configure the secondary reflector 58 to have a single reflecting surface and to configure the secondary reflector 58 as an element independent of the support element 50. In addition, it is also possible that the reflector secondary 58 is provided not only in each fire unit 20B but also in each fire unit 20A.
    According to the example embodiment described above, the reflector 30A of each light unit 20A is arranged on the lower sides of the first and second light emitting elements 22A and 24A, and the reflector 30B of each light unit 20B is arranged on the lower sides of the first and second light emitting elements 22B and 24B. However, it is also possible to arrange the reflector 30A of each light unit 20A in a position other than the lower side (for example the upper side or the transverse side).
    According to the example embodiment described above, a first lighting mode is a headlight lighting mode and a second lighting mode is a daytime running light lighting mode. However, it is also possible to adopt a combination of other lighting modes (for example the first lighting mode is a lighthouse lighting mode and the second lighting mode is a fire lighting mode clearance).
    Next, a modification of the present exemplary embodiment will be described.
    A first modification of this example embodiment will first be described.
    [0096] The figure 5 is a view illustrating a fire of vehicle 110 according to the current modification, who East the even that Figure 2. [0097] Like this is illustrated in this figure, the
    Basic configuration of vehicle light 110 is the same as vehicle light 10 according to the example embodiment described above, but the present modification is different from the example embodiment described above in that that a secondary light source unit 160 is additionally arranged to be turned on in the daytime running light lighting mode.
    The secondary light source unit 160 includes a pillar-shaped light guide 162 which extends in the vehicle width direction on the front side of the first light emitting element 22A in the unit 120A of fire and a light emitting element (not shown) such as a white light emitting diode provided to cause light to be incident from the end surface of the light guide 162 to the light guide 162.
    In addition, the secondary light source unit 160 reflects light from the guided light emitting element in the light guide 162 on the inner surface of a plurality of reflective elements 162s formed in the upper part of the peripheral surface of the light guide 162 and then emits light from the lower part of the light guide 162 to the first reflecting surface 30Aal of the reflector 30A.
    At this time, since the light guide 162 is positioned in front of the first light emitting element 22A, the light emitted by the light guide 162 which is incident on the first reflecting surface 30Aal is reflected as that light obliquely upwards.
    In addition, in the present modification, since the light guide 162 is provided, the support element 150 has a shape different from the lower surface of the thin-walled part 152 in the example embodiment described above. However, the thick-walled portion 154 and the light mask portion 156 have the same shapes as in the example embodiment described above.
    By adopting the configuration of the present modification, it is possible for the first reflecting surface 30Aal to emit stronger light in the daytime running light illumination mode. A second modification of the present exemplary embodiment will then be described.
    FIG. 6 is a view illustrating a vehicle light 210 according to this modification, which is the same as FIG. 2.
    As illustrated in FIG. 6, the basic configuration of the vehicle light 210 is the same as the vehicle light 10 according to the example embodiment described above, but the present modification is different from the exemplary embodiment described above in that a secondary light emitting element 226A is additionally provided as a secondary light source unit configured to be turned on in the illumination mode daytime running light.
    The secondary light emitting element 226A is a white light emitting diode and is arranged downward on the front side of the first light emitting element 22A in the light unit 220A.
    In the present modification, a substrate 240 on which the first and second light-emitting elements 22A and 24A are mounted has a shape in which the substrate 40 of the example embodiment described above is extended. towards the front, and the secondary light-emitting element 226A is also mounted on the lower surface of the substrate 40.
    Since the secondary light emitting element 226A is positioned in front of the first light emitting element 22A, the light emitted by the secondary light emitting element 226A which is incident on the first reflecting surface 30Aal is reflected as light obliquely upwards.
    In addition, in the present modification, since the secondary light-emitting element 226A is provided, the support element 250 has a shape different from the lower surface of the thin-walled portion 252 in the form of example embodiment described above. However, the thick-walled portion 254 and the light mask portion 256 have the same shapes as in the example embodiment described above.
    By adopting the configuration of the present modification, it is possible to cause the first reflecting surface 30Aal to emit stronger light in the daytime running light illumination mode. A third modification of the present exemplary embodiment will then be described.
    [0112] Figure 7 is a view illustrating a fire of vehicle 310 according to this modification, which East the even that Figure 2. [0113] As illustrated in the figure 7, the
    Basic configuration of vehicle light 310 is the same as vehicle light 10 according to the example embodiment described above, but the present modification is different from the example embodiment described above in that the first light emitting element 22A of the fire unit 320A is configured to be lit in the daytime running light lighting mode in a state lower than the lighting period of the lighting mode lighthouse.
    That is, in the daytime running light mode, the second light emitting element 24B is turned on, and the first light emitting element 22A is weakened. Therefore, a light distribution pattern is formed as a daytime running light distribution pattern, in which a light distribution configuration with reduced brightness of the additional light distribution configuration PA illustrated in Fig. 4B is superimposed on the PD daytime running light distribution configuration illustrated in FIG. 4C.
    By adopting the configuration of this modification, the reflector 30A can be caused to emit light over a wide range in the daytime running light mode without using a new element.
    A fourth modification of the present exemplary embodiment will then be described.
    FIG. 8 is a view illustrating a vehicle light 410 according to this modification, which is the same as FIG. 2.
    As illustrated in Figure 8, the basic configuration of the vehicle light 410 is the same as the vehicle light 10 according to the exemplary embodiment described above. However, this modification is different from the example embodiment described above in that the positional relationship between the first and second light emitting elements 22A and 24A in the light unit 420A is reversed by back and forth. Thus, the configurations of the reflector 430A (and of the continuous body of the reflector 430), of the substrates 442 and 444, and of the support element 450 of the present modification are different from those of the exemplary embodiment described above. above.
    In this modification, the second light emitting element 24A is positioned on the lower side of an inclined part on the front side relative to the first light emitting element 22A. For this reason, the substrate 442 on which the first light emitting element 22A is mounted and the substrate 444 on which the second light emitting element 22B is mounted are formed as separate substrates.
    In the present modification, the reflector 430A is formed in two upper and lower stages so that the first reflecting surface 430Aal is positioned on the lower side of the second reflecting surface 430Aa2.
    However, the first reflective surfaces
    430Aal and the second reflective surface 430Aa2 of the present modification have shapes different from those of the example embodiment described above so that the first reflective surface 430Aal reflects the light emitted by the first emission element of light 22A towards the front of the vehicle as light slightly scattered in the vertical direction and the second reflecting surface 430Aa2 reflects the light emitted by the second light-emitting element 24A towards the front of the vehicle as light slightly scattered in the vertical direction.
    The support element 450 comprises a thin-walled part 452, a thick-walled part 454, and a light mask part 456, but their shape is very different from that in the example embodiment described above.
    That is to say that the thin-walled part 452 is positioned lower than that in the example embodiment described above and supports the substrate 444 on its upper surface. The thick-walled portion 454 is formed to be thicker than that in the example embodiment described above and supports the substrate 442 on its upper surface, while supporting the rim portion 430a of the continuous reflector body 430 on its lower surface. Likewise, the light mask part 456 is formed as a part of the thick-walled part 454 so as to be positioned near the rear side of the first light emitting element 22A in order to mask the light from the first light element emitting light 22A to the second reflecting surface 430Aa2 of the reflector 430A.
    That is to say that, even in the case of the adoption of the configuration of the present modification, once the first reflecting surface 430Aal on which the light emitted by the first light emitting element 22A is incident is preferably used as a reflective area configured to form the additional light distribution pattern PA for the high beam light distribution configuration PH, the first and second reflective surfaces
    430Aal and 430Aa2 on which the light emitted from the second light emitting element 24A is incident can be used as reflective areas configured to form a daytime running light distribution pattern PD.
    At this time, since the light emitted by the first light emitting element 22A is not incident on the second reflecting surface 430Aa2, the second reflecting surface 430Aa2 can be used
    as a dedicated reflective area configured for form a distribution configuration of light of fire of PD day shift. [0126] Thus, once the configuration of fire light distribution of road PH and the distribution configuration of light of fire of
    daytime running light PD can be effectively formed, the first and second reflecting surfaces 430Aal and 430Aa2 can both be caused to emit light in the daytime running light lighting mode.
    Furthermore, it should be understood that the numerical values illustrated as a description in the exemplary embodiment described above and the modifications thereof are merely examples and that the numerical values can be established from appropriately to different values.
    From the above, it will be appreciated that different exemplary embodiments of the present invention have been described here for the purpose of illustration, and that different modifications can be made without departing from the scope. demands. The various exemplary embodiments disclosed herein are therefore not intended for limitation purposes.
