    The present application claims priority from Japanese patent application No. 2017-023417, filed on February 10, 2017.
    The present invention relates to a lamp device to be mounted on a vehicle.
    In order to make an aid for driving a vehicle, it is necessary to mount a sensor on a vehicle body in order to acquire information outside the vehicle. A lamp device is known comprising a sensor arranged in a lamp housing intended to house a light source for emitting light towards a predetermined area around a vehicle (see for example the document JP-A-2016-187990) .
    A housing space for housing the light source and the sensor is defined by the lamp housing and a translucent element fixed on the lamp housing. As described above, the sensor arranged in the housing space acquires information outside the vehicle through the translucent element. The translucent member can be generally formed by applying a hard layer on an outer surface of polycarbonate resin. In this case, when the light transmission characteristics of the translucent element change with long-term use, an accuracy of information acquisition by the sensor can be affected.
    [0006] Consequently, one aspect of the present invention provides a lamp device which comprises a light source and a sensor arranged in a space defined by a translucent element and a housing and can maintain a precision of information acquisition by the sensor over a long period.
    According to one aspect of the present invention, there is provided a lamp device to be mounted on a vehicle, the lamp device comprising:
    housing ;
    a translucent element defining a housing space with the housing;
    a light source housed in the accommodation space; and a sensor housed in the accommodation space and configured to detect information outside the vehicle, wherein the translucent member comprises a first portion and a second portion, wherein the first portion comprises an area through which passes light from the light source and has a first weather resistance, and wherein the second portion includes an area which faces the sensor and has a second weather resistance, and the second weather resistance is higher as the first weather resistance. In the above lamp device, the sensor can comprise at least one of a lidar sensor (“Light Detection And Ranging” which can be translated by “detection and estimation of the distance by light”), a millimeter wave radar, an ultrasonic sensor, and a camera.
    That is to say, the translucent element defining the housing space intended to house the light source and the sensor with the housing comprises the first portion and the second portion having a different weather resistance. In the second portion having higher weather resistance, the light transmitting characteristic hardly changes with long time use. Since the second portion includes the area facing the sensor, accuracy of information acquisition by the sensor over a long period of time can be maintained.
    In the above lamp device, the second portion can be made from one of a glass, an acrylic resin, or a bio-polycarbonate resin.
    The above lamp device may further comprise an opaque element covering at least part of a first end edge of the first portion and at least part of a second end edge of the second portion.
    Alternatively, the above lamp device may include an opaque member having a portion which is flush with at least one (i) of at least a portion of a first end edge of the first portion and (ii) at least part of a second end edge of the second portion.
    According to these configurations, it is possible to make it difficult to visually identify a limit between the first portion and the second portion with a different weather resistance. Therefore, an artificial feeling given to a user with long-term use can be suppressed even if the translucent member has the first portion and the second portion with different weather resistance. In the above lamp device, the opaque element may have the same color as part of a vehicle body of the vehicle.
    According to this configuration, it is possible to provide a natural appearance for the opaque element, which makes it difficult to visually identify the limit between the first portion and the second portion of the translucent element with different weather resistance, as if it were part of the vehicle body. The artificial sensation given to the user with long-term use can still be suppressed even if the translucent element has the first portion and the second portion with different weather resistance.
    In the above lamp device, the second portion can be smaller than the first portion.
    If the entire translucent element was formed with a material having higher weather resistance, different problems would be considered. For example, an acrylic resin has poorer impact resistance compared to a polycarbonate resin and the like. However, if the second portion occupying a relatively small area of the translucent member is made of acrylic resin, it is easy to obtain the desired impact resistance. Glass has a high impact resistance but has a problem of weight and freedom of molding (that is to say freedom of design). However, if the second portion occupying a relatively small area of the translucent member is made of glass, the influence on the weight of the entire translucent member and the design freedom can be reduced.
    In the above lamp device, the second portion may include a portion having a lens function.
    According to this configuration, at least part of an optical system arranged in the housing space for the sensor to operate can be omitted. Therefore, an increase in size of the lamp device can be suppressed.
    In the above lamp device, the first portion and the second portion may be part of a self-molded product.
    According to this configuration, the number of parts can be reduced.
    The above and other aspects of the present invention will become more apparent and will be more readily appreciated from the following description of illustrative embodiments of the present invention taken in conjunction with the accompanying drawings, in which :

    Embodiments will be described in detail below with reference to the drawings. In each drawing used in the following description, the scale is changed appropriately in order to bring each element to a recognizable size.
    In the drawings, the arrow F indicates a forward direction of an illustrated structure. The arrow B indicates a rearward direction of the illustrated structure. The arrow ü indicates an upward direction of the illustrated structure. The arrow D indicates a downward direction of the illustrated structure. The arrow L indicates a left direction of the illustrated structure. The arrow R indicates a straight direction of the structure shown. "Left" and "right" used in the following description indicate the left and right directions seen from a driver's seat.
    As shown in Figure 1, a left front lamp device 1LF according to a first embodiment is mounted on a left front corner portion of a vehicle 100. A right front lamp device 1RF according to the first embodiment is mounted on a right front corner portion of the vehicle 100.
    Figure 2 schematically shows an internal configuration of the right front lamp device 1RF seen from above the vehicle 100. Although the drawing is omitted, the left front lamp device 1LF has a configuration which is symmetrical with the device of 1RF right front lamp.
    The right front 1RF lamp device comprises a housing 11 and a translucent element 12. The housing 11 and the translucent element 12 define a lamp chamber (an example of a housing space).
    The right front lamp device 1RF comprises a light source 14. The light source 14 comprises an optical system comprising at least one of a lens and a reflector and emits light to illuminate a predetermined area. The light source 14 is disposed in the lamp chamber 13. A lamp light source and / or a semiconductor light emitting element can be used in the light source 14. Examples of the light source lamp light include an incandescent lamp, a halogen lamp, a discharge lamp, a neon lamp and the like. Examples of the semiconductor light emitting element include a light emitting diode, a laser diode, an organic light emitting element and the like. The 1RF right front lamp device comprises a lidar sensor 15. The lidar sensor 15 comprises an element intended to emit invisible light and an element intended to detect return light resulting from the reflection of invisible light on an object present outside the vehicle 100. In this embodiment, infrared light having a wavelength of 905 nm is used as invisible light. The lidar sensor 15 may include a scanning mechanism for scanning invisible light by changing a direction of emission (i.e., a direction of detection).
    The lidar sensor 15 is a sensor intended to acquire information outside the vehicle 100. For example, a distance to an object associated with the return light can be acquired on the basis of a duration between a time of emission of infrared light in a certain direction and a time of detection of return light. In addition, information on a shape of the object associated with the return light can be acquired by accumulating this distance data associated with the detection positions. Alternatively or additionally, information on an attribute, such as a material, of the object associated with the return light can be acquired based on a difference between the emitted light and the return light . As a variant or additionally, information on a color of the object (a white line, etc. on a road surface) can be acquired on the basis of a difference in a reflectivity of the return light from the road surface, for example.
    The lidar sensor 15 delivers a signal corresponding to the detected attribute (intensity, wavelength, or equivalent) of the return light. The above information is acquired by appropriately processing the signal delivered by the lidar sensor 15 using an information processing unit or a processor (not shown). The information processing unit or processor can be included in the right front lamp device 1RF, or can be mounted in vehicle 100.
    The translucent element 12 comprises a first portion 121 and a second portion 122. The first portion 121 comprises an area through which the light emitted by the light source 14 passes. More specifically, the first portion 121 is disposed of so as to cover at least one irradiation range (a solid angle) of the light emitted by the light source 14. The second portion 122 comprises an area which faces the lidar sensor 15. More specifically, the second portion 122 is arranged so as to cover at least one detection range (a solid angle) of the lidar sensor 15.
    The light emitted by the light source 14 passes through the first portion 121 of the translucent element 12 and illuminates the predetermined area outside the vehicle
    100. At least part of the wavelength of the light emitted by the light source 14 is included in a visible light area.
    The infrared light emitted by the lidar sensor 15 passes through the second portion 122 of the translucent element 12 and irradiates the predetermined area outside the vehicle 100. A range S indicated by a dotted line in the figure 2 represents a range which can be irradiated (detected). The return light which results from a reflection by the irradiated object passes through the second portion 122 and is detected by the lidar sensor 15.
    The first portion 121 has a first weather resistance. The term "weather resistance" refers to longevity against degradation due primarily to sunlight, rain and snow, temperature, humidity, and ozone in a natural environment. The term "weather resistance is high" refers to the fact that such longevity is high. The second portion 122 has a second weather resistance. The second weather resistance is higher than the first weather resistance. That is, the weather resistance of the second portion 122 is higher than the weather resistance of the first portion 121. The first portion 121 is made, for example, of polycarbonate resin. The second portion 122 is made, for example, of glass, acrylic resin, and bio-polycarbonate resin. A combination of a material to form the first portion 121 and a material to form the second portion 122 can be appropriately selected so as to satisfy the above relationship of weather resistance.
    That is to say that the translucent element 12 defining the lamp chamber 13 intended to house the light source 14 and the lidar sensor 15 with the housing comprises the first portion 121 and the second portion 122 having the different weather resistance. In the second portion 122 having a higher weather resistance, the light transmission characteristic hardly changes with long-term use. Since the second portion 122 comprises the zone which faces the lidar sensor 15, the accuracy of information acquisition by the lidar sensor 15 over a long period can be maintained.
    In this embodiment, the first portion
    121 and the second portion 122 of the translucent element 12 are in contact with one another. The first portion 121 and the second portion 122 may be bonded by bonding or welding, or may be provided as a self-molded product in advance. In the latter case, the number of parts can be reduced.
    In this embodiment, the second portion
    122 of the translucent element 12 is smaller than the first portion 121.
    If the entire translucent member 12 was formed from a material having higher weather resistance, various problems would be considered. For example, acrylic resin has poorer impact resistance compared to polycarbonate resin and the like. However, if the second portion 122 occupying a relatively small area of the translucent element 12 is made of acrylic resin, it is easy to obtain the desired impact resistance. Glass has a high resistance to impact but has a difficulty in weight and freedom of molding (that is to say of freedom of design). However, if the second portion 122 occupying a relatively small area of the translucent member 12 is made of glass, the influence on the weight of the entire translucent member 12 and the design freedom can be reduced.
    Figure 3 schematically shows a right front lamp device 1RF1 according to a first modification of the first embodiment. Constituent elements common to the 1RF right front lamp device are designated by the same references, and a repetitive explanation is omitted.
    In this modification, an anti-reflection layer 124 is provided on an inner surface of the second portion 122 of the translucent element 12. The anti-reflection layer 124 has a so-called cross-linked structure. More specifically, a convex-concave structure is formed which is repeated at a cycle shorter than the wavelength of the light detected from the lidar sensor 15.
    According to this configuration, the light transmittance of the light detected from the lidar sensor 15 in the second portion 122 can be improved. Consequently, the accuracy of information acquisition by the lidar sensor 15 can be improved and the accuracy can be maintained over a long period.
    Figure 4 is a drawing schematically showing a right front lamp device 1RF2 according to a second modification of the first embodiment. Constituent elements common to the 1RF right front lamp device are designated by the same references, and a repetitive explanation is omitted.
    The right front lamp device 1RF2 comprises a wall element 125. The wall element 125 separates a space between the interior surface of the second portion 122 of the translucent element 12 and the lidar sensor 15. The space is filled with silicone gel 126.
    According to this configuration, the inner surface of the second portion 122 which the lidar sensor 15 faces can be avoided from being veiled. In addition, part of the material component forming the second portion 122 can be prevented from being volatilized in the lamp chamber 13 when the temperature rises. Consequently, the accuracy of information acquisition by the lidar sensor 15 can be improved, and the accuracy can be maintained over a long period. In addition, the lidar sensor 15 opposite the second portion 122 can be protected against impact and contamination by the silicone gel 126.
    The silicone gel 126 can be replaced by another gel material as long as the gel material can provide sufficient light transmittance (80% or more for example) relative to the light detected from the lidar sensor 15.
    In the above embodiments, the detected light from the lidar sensor 15 passes linearly through the second portion 122 of the translucent element 12. However, at least part of the second portion 122 may have a shape having a lens function.
    According to this configuration, since the lidar sensor 15 performs the desired detection operation, at least part of the optical system arranged in the lamp chamber 13 can be omitted. Therefore, an increase in size of the 1RF right front lamp device can be suppressed.
    In the above embodiments, a single housing space (the lamp chamber 13) is defined by the housing 11 and the translucent element 12. However, the interior of the housing space can be divided into a plurality of spaces by a partition plate and the like.
    Figure 5 schematically shows an aspect of a 2LF left front lamp device mounted on the vehicle
    100, according to a second embodiment. FIG. 6 schematically shows an internal configuration of the left front lamp device 2LF seen from the left of the vehicle 100.
    The left front lamp device 2LF comprises a housing 21 and a translucent element 22. The housing 21 and the translucent element 22 define a lamp chamber 23 (an example of the housing space).
    The left front lamp device 2LF comprises a light source 24. The light source 24 comprises an optical system comprising at least one of a lens and a reflector and emits light to illuminate a predetermined area. The light source 24 is disposed in the lamp chamber 23. A lamp light source and / or a semiconductor light emitting element can be used in the light source 24. Examples of the light source lamp light include an incandescent lamp, a halogen lamp, a discharge lamp, a neon lamp and the like. Examples of the semiconductor light emitting element include a light emitting diode, a laser diode, an organic light emitting element and the like. The left front lamp device 2LF comprises a camera 25. The camera 25 is a device which acquires an image at least of the front of the vehicle 100 (an example of the exterior of the vehicle). That is to say that the camera 25 is a sensor which detects information at least in front of the vehicle 100. The camera 25 is configured to deliver an image signal corresponding to the acquired image. The information on at least the front of the vehicle 100 detected by the camera 25 is acquired by appropriately processing the image signal by means of an information processing unit or a processor (not shown). The information processing unit or processor can be included in the left front lamp device 2LF, or can be mounted in vehicle 100.
    The translucent element 22 comprises a first portion 221 and a second portion 222. The first portion 221 comprises an area through which the light emitted by the light source 24 passes. More specifically, the first portion 221 is arranged with so as to cover at least one irradiation range (a solid angle) of the light emitted by the light source 24. The second portion 222 comprises an area opposite the camera 25. More specifically, the second portion 222 is arranged to cover at least one visual field of the camera 25.
    The light emitted by the light source 24 passes through the first portion 221 of the translucent element 22 and illuminates the predetermined area outside the vehicle 100. At least part of the wavelength of the light emitted by the light source 24 is included in an area of visible light.
    The camera 25 takes an image of at least the front of the vehicle 100 on the basis of the light which passes through the second portion 222 of the translucent element 22.
    The first portion 221 has a first weather resistance. The second portion 222 has a second weather resistance. The second weather resistance is higher than the first weather resistance. That is, the weather resistance of the second portion 222 is higher than the weather resistance of the first portion 221.
    The first portion 221 is made, for example, of polycarbonate resin. A hard coat is applied to an exterior surface thereof. The second portion 222 is made, for example, from glass, acrylic resin, or bio-polycarbonate resin. A combination of a material intended to form the first portion 221 and a material intended to form the second portion 222 can be appropriately selected so as to satisfy the above relationship of weather resistance.
    That is to say that the translucent element 22 defining the lamp chamber 23 intended to house the light source 24 and the camera 25 with the housing comprises the first portion 221 and the second portion 222 having the different weather resistance. In the second portion 222 having a higher weather resistance, the light transmission characteristic hardly changes with long-term use. Since the second portion 222 comprises the zone opposite the camera 25, the accuracy of information acquisition by the camera 25 over a long period can be maintained.
    In this embodiment, the 2LF left front lamp device comprises an opaque element 26. The opaque element 26 is made, for example, of opaque resin.
    As shown in Figure 5, the opaque member 26 extends along an outer surface of the translucent member 22. More specifically, as shown in Figure 6, the opaque member 26 extends so as to cover an end edge 221a (an example of a first end edge) of the first portion 221 and an end edge 222a (an example of a second end edge) of the second part 222 of the translucent element 22. In this embodiment, as shown in FIG. 5, the opaque element 26 covers an entire boundary 223 which is between the first portion 221 and the second part 222 and formed by the end edge 221a and the end edge 222a.
    In the present description, the term "opaque" used for the opaque element 26 does not necessarily mean only a state where no visible light is transmitted. The transmittance of the opaque element 26 for visible light should be included in an "opaque" range if the transmittance is less than the transmittance of the translucent element 22 for visible light.
    According to this configuration, it is possible to make it difficult to visually identify the limit 223 between the first portion 221 and the second part 222 with a different weather resistance. Therefore, an artificial feeling given to a user with long-term use can be suppressed even if the translucent member 22 has the first portion 221 and the second portion 222 with different weather resistance.
    In this embodiment, the opaque element 26 has the same color as part of a vehicle body 101 of the vehicle 100 (in particular a part adjacent to the left front lamp device 2LF).
    According to this configuration, a natural appearance can be provided in which the opaque element 26, which makes it difficult to visually identify the limit between the first portion 221 and the second part 222 of the translucent element 22 with a different weather resistance, is a part of the vehicle body 101. The artificial feeling given to a user with long-term use can still be suppressed even if the translucent element 22 has the first portion 221 and the second part 222 with different weather resistance.
    In this embodiment, the first portion
    221 and the second part 222 of the translucent element 22 are in contact with one another. The first portion 221 and the second portion 222 may be bonded, or may be provided as a product molded in one piece in advance. In the latter case, the number of parts can be reduced.
    In this embodiment, the second part 222 of the translucent element 22 is smaller than the first portion 221.
    If the entire translucent member 22 was formed from a material having higher weather resistance, various problems would be considered. For example, an acrylic resin has poorer impact resistance compared to polycarbonate resin and the like. However, if the second part 222 occupying a relatively small area of the translucent element 22 is made of acrylic resin, it is easy to obtain the desired impact resistance. Glass has a high impact resistance but has a difficulty in weight and freedom of molding (that is to say freedom of design). However, if the second part 222 occupying a relatively small area of the translucent member 22 is made of glass, the influence on the weight of the entire translucent member 22 and the freedom of design can be reduced.
    Figure 7 shows a left front lamp device 2LF1 according to a first modification of the second embodiment. Constituent elements common to the 2LF left front lamp device are designated by the same references, and a repetitive explanation is omitted. The left front lamp device 2LF1 comprises an opaque element 261. The opaque element 261 has an end surface 261a which is flush with the end edge 221a of the first portion 221 and the end edge 222a of the second part 222 of the translucent element 22.
    Even with this configuration, it is possible to make it difficult to visually identify the limit 223 between the first portion 221 and the second part 222 with a different weather resistance. Therefore, the artificial feeling given to a user with long-term use can be suppressed even if the translucent member 22 has the first portion 221 and the second portion 222 with different weather resistance.
    If it is possible to obtain the effect of making it difficult to visually identify the limit 223, the end surface 261a of the opaque element 261 can be arranged so as to form a slight bearing between the end edge 221a of the first portion 221 and the end edge 222a of the second part 222.
    In the left front lamp device 2LF and the left front lamp device 2LF1, the end edge 221a of the first portion 221 and the end edge 222a of the second part 222 of the translucent element 22 are in contact with each other. However, these do not necessarily have to be in contact with each other. Figure 8 shows a left front lamp device 2LF2 according to a second modification of the second embodiment for this case. Constituent elements common to the 2LF left front lamp device are designated by the same references, and a repetitive explanation is omitted.
    The left front lamp device 2LF2 comprises an opaque element 262. The opaque element 262 has a first outer end 262a and a second outer end 262b. The first outer end 262a is in contact with the end edge 221a of the first portion 221 of the translucent element 22. The second outer end 262b is in contact with the end edge 222a of the second part 222 of the translucent element 22.
    The opaque element 262 and the first portion 221 and the second part 222 of the translucent element 22 can be bonded by adhesion, welding and the like, or can be provided as a molded product in one piece. advanced. In the latter case, the number of parts can be reduced.
    In the left front lamp device 2LF, the opaque element 26 covers the entire end edge 221a of the first portion 221 and the entire end edge 222a of the second part 222 of the translucent element 22. However, the opaque element can cover at least a part of at least one of the end edge 221a and of the end edge 222a. Figure 9 shows a left front lamp device 2LF3 according to a third modification of the second embodiment for this case. Constituent elements common to the 2LF left front lamp device are designated by the same references, and a repetitive explanation is omitted.
    The left front lamp device 2LF3 comprises an opaque element 263. The opaque element 263 covers part of the limit 223 formed by the end edge 221a of the first portion 221 and the end edge 222a of the second part 222 of the translucent element 22.
    In the above embodiments, the light emitted on the camera 25 passes linearly through the second part 222 of the translucent element 22. However, at least part of the second part 222 can have a shape having a lens function.
    According to this configuration, since the camera 25 performs the desired shooting operation, at least part of the optical system arranged in the lamp chamber 23 can be omitted. Therefore, an increase in size of the 2LF left front lamp device can be suppressed.
    In the above embodiments, a single housing space (the lamp chamber 23) is defined by the housing 21 and the translucent element 22. However, the interior of the housing space can be divided into a plurality of spaces by a partition plate and the like.
    Each of the above embodiments is simply an example to facilitate understanding of the present invention. The configuration according to each of the embodiments can be appropriately modified or improved without departing from the scope of the present invention. In addition, it is obvious that equivalents fall within the technical scope of the present invention.
    The anti-reflection layer 124 described with reference to the right front lamp device 1RF1 in FIG. 3 can be applied to the interior surface of the second part 222 of the translucent element 22 described with reference to FIGS. 5 to 9.
