    [003] Patent Document 1 discloses an LED lighting unit that has two types of reflectors for a low beam and a high beam and in which the change between a low beam and a high beam is carried out by changing the direction of the irradiation of the LED with the use of an actuator. In this lighting unit, a heat sink as a cooling mechanism is provided on a side portion of an LED panel which is essentially moved by the actuator.
    [004] In the meantime, Patent Document 2 discloses another LED lighting unit for a vehicle in which a panel on which an LED for a low beam is mounted and a panel on which another LED for a high beam is mounted are arranged in a separate relationship from each other so that the LED mounting faces for the LEDs are conducted in the upward and downward directions.

Therefore, the cooling fins can be formed in a size increased to the maximum.
    [0023] According to the seventh characteristic, the two members similar to the plate are separated and fixed to each other with the spacer interposed between them, and the cooling fins are arranged so as not to keep contact with any other member in the direction vertical. Therefore, an installation property is improved and also the cooling performance for the LEDs and so on can be improved.

    [0033] In the following, a preferred embodiment of the present invention is described in detail with reference to the drawings. FIG. 1 is a front elevation view of a motorcycle 1 to which an LED lighting unit 2, according to an embodiment of the present invention, is applied. A front wheel WF of motorcycle 1 is supported on a vehicle body composition (not shown) by a pair of front forks 7 in a direction the width of the vehicle. A driving handlebar 9 for driving the front wheel WF is attached to an upper portion of the front forks 7, and a pair of left and right rear view mirrors 8 is attached to the driving handlebar 9. A motor 17 is arranged substantially in the center on a forward and backward direction of the vehicle body between the front wheel WF and a rear wheel WR. In addition, a pair of right and left foot support brackets 19 are attached to a lower portion of the engine 17, and foot support brackets 12 for a passenger are attached to the rear side of the vehicle body in relation to the engine 17.
    [0034] The front forks 7 are covered in an upper portion of them with hoods 14 since a pair of outer parts in the direction of the vehicle width and direction indicator devices 10 are attached to the hoods 14. A front hood 11 is attached to the front side of the vehicle body in relation to the steering handle 9 above the hoods 14. The LED lighting unit 2 for a vehicle (hereinafter referred to sometimes as the LED lighting unit) according to the present invention is attached to the front hood 11 from the rear side of the face of the front hood 11. LED lighting unit 2 is a front beam that uses a light-emitting diode as a light source. A through hole 3 is provided in an extension (referring to FIG. 3) disposed on the inside of an external lens 4 so that a reflector to reflect irradiation light to the front of the vehicle is exposed through it.
    [0035] FIG. 2 is a front elevation view of the LED lighting unit 2. However, FIG. 3 is a front elevation view of the LED lighting unit 2 in a state in which the outer lens 4 and the extension 23 are removed. The LED lighting unit 2 is configured by attaching an LED unit 30 to a base member 20 which is a fixing portion next to the vehicle body, securing the extension 23 to cover the LED unit 30 and additionally securing the external lens 4. The external lens 4 has a shape conforming to the contour shape of the base member 20. The extension 23 and the external lens 4 are fixed to the base member 20.
    [0036] Four fixing brackets 21 for attaching the LED lighting unit 2 to the front hood 11 are provided on a peripheral edge of the base member 20 which is formed from a resin of a black or similar color. The LED lighting unit 2 is configured so that when it is attached to the rear face side of the front hood 11 using threaded holes 22 formed in the fixing brackets 21, only one face of the lens of the LED lighting unit 2 on the inner side of a portion indicated by the dotted line in the drawings is exposed in front of the vehicle body through the opening of the front hood 11.
    [0037] LED unit 30 includes LED devices 60 and 70 formed from LEDs 32a and 42a and panels 32 and 42 that support LEDs 32a and 42a, respectively. The LED unit 30 is supported for oscillating movements around a lower portion on the left side thereof in the direction of the width of the vehicle in relation to the base member 20 with a support axis 47 as a center. The LED unit 30 is additionally configured so that the adjustment of its optical axis in the vertical direction can be carried out by an adjustment mechanism 37 provided in an upper portion on the left side of the LED unit 30 in the direction of the vehicle width. The LED unit 30 is additionally configured so that the adjustment of the optical geometric axis of the same in the horizontal direction can be carried out by another adjustment mechanism 58 provided in a lower portion of the right side of the LED unit 30 in the direction of the vehicle width. .
    [0038] Extension 23 is formed from a transparent colored resin, for example, smoke-colored and has a function that exposes forward only reflectors 34 and 44, which reflect irradiation light from the light source in front of the vehicle body, through the through hole 3 and disguise the external portions in relation to the reflectors 34 and 44 so that they are not visually recognized from the outside.
    [0039] Reference is also made to FIG. 4. FIG. 4 is a perspective view of LED unit 30. LED unit 30 is configured by joining a member similar to the low beam plate 31 (upper side of the vehicle body) on which the low beam LED device 60 is mounted and a member similar to the high beam plate 41 (lower side of the vehicle body) on which the high beam LED device 70 is mounted. The low beam LED device 60 and the high beam LED device 70 are attached to the member similar to the low beam plate 31 and to the member similar to the high beam plate 41, respectively, individually by two screws 57. In the present embodiment , the member similar to the low beam plate 31 and the member similar to the low beam plate 41 have a substantially equal structure and, therefore, in the following description, portions thereof that have the same structure are described with respect to the member similar to low beam plate 31 as a representative.
    [0040] In the member similar to the low beam plate 31 (member similar to the high beam plate 41), a mounting face 31b of the low beam LED device 60 (high beam LED device 70) is located in one direction substantially horizontal and the low beam reflector 34 (high beam reflector 44) is fixed to the mounting face 31b with the use of mounting screws 54. The low beam reflector 34 (high beam reflector 44) is curved to cover the low beam LED device 60 from above (covers the high beam LED device 70 from below). Since reflectors 34 and 44 are configured as separate parts of members similar to plates 31 and 41, it is possible to form members similar to plates 31 and 41 from a metal that is superior in heat dissipation and form reflectors 34 and 44 from a synthetic resin or similar to which deposition or metal coating is applied. Consequently, a lighting unit can be formed with low cost and weight and which is superior in relation to heat dissipation.
    [0041] It should be noted that LED unit 30 in this mode is configured so that, from the selection of a low beam, only the LED of the low beam LED 32a is switched on, but from the selection of a beam high, only the high beam LED 42a is on. However, LED unit 30 can otherwise be configured so that, for example, from the selection of a high beam, both LEDs 32a and 42a are switched on simultaneously. Or, the amounts of light from the LED device 60 and 70 can be made differently from each other or the reflectors 34 and 44 can have different shapes between them.
    [0042] The LED lighting unit 2, according to the present modality, is characterized in that both the high cooling performance for both devices 60 and 70 and the reduction in the size of the LED unit 30 are achieved through the fixing the member similar to the low beam plate 31 and the member similar to the high beam plate 41 in a state in which a predetermined space 50 is ensured between them.
    [0043] The member similar to the low beam plate 31 and the member similar to the low beam plate 41 are fastened to the opposite end portions in the longitudinal direction by nut bolts 51 with spacers 52, the opposite ends of which are of a cylindrical shape, interposed between them. In this way, the space 50 for cooling is provided by the spacers 52. A plurality of cooling fins 35 provided on a lower face of the member similar to the low beam plate 31 and a plurality of cooling fins 45 provided on an upper face of the member similar to the high beam plate 41 extending in an opposite relationship from each other to the space 50. In other words, the cooling fins 35 and 45 are arranged so that the longitudinal direction of the same is conducted perpendicularly to the longitudinal direction of the members similar to the plate 31 and 41. With the configuration described, the space between the members similar to the upper and lower plate 31 and 41 can be used effectively to improve the cooling performance for the LED device 60 and 70 and the members similar to plate 31 and 41.
    [0044] According to the configuration described above, the members similar to the plate 31 and 41 are fixed in a separate relation to each other with the spacers 52 interposed between them so that the cooling fins 35 and 45 are arranged so not to maintain contact with any other member in the vertical direction. Therefore, the installation property is improved and the cooling performance for the LEDs is also improved. It should be noted that the plate-like members 31 and 41 can be formed from a resin, a metal or the like, and the cooling fins 35 and 45 can be formed from a metal such as aluminum and attached to similar members to plate 31 and 41 by a binding agent, a fixing member or the like.
    [0045] The air that passes in space 50 flows in the forward and backward directions of the vehicle body along the direction of formation of the cooling fins 35 and 45 and also flows in the directions of the width of the vehicle through intervals 52a formed in the end portions of cooling fins 35 and 45 in longitudinal directions.
    [0046] Additionally, an erected portion 31a is provided on an end portion of the member similar to the low beam plate 31 on the rear side of the vehicle body so that it is driven upwards in the vertical direction. However, an erected portion 41a is provided on an end portion of the member similar to the high beam plate 41 on the rear side of the vehicle body so that it is driven downwards in the vertical direction. The raised portions 31a and 41a form another plane substantially perpendicular to the mounting faces 31b and 41b of the LED devices 60 and 70, respectively. Additionally, in the present embodiment, the members similar to the plate 31 and 41 and the erected portions 31a and 41a are individually integrally formed with each other so that the members similar to the plate, in general, have a substantially shaped cross-sectional shape from L.
    [0047] For the portion erected 31a on the upper side of the vehicle body, a plate-like anchoring anchor 36 is attached, and the adjustment mechanism 37 is attached to a left end portion in the direction of the vehicle width. of the anchoring pole 36. However, for the portion erected 41a on the underside of the vehicle body, a anchoring anchor 46 and another anchoring anchor 55 are attached. The support axis (aiming at articulation) 47 is fixed to a left end portion in the direction of the vehicle width of the anchoring rod 46, and an adjustment mechanism 58 is attached to a right end portion in the direction of the width of the vehicle. fixing rod vehicle 46. Fixing rods 46 and 55 are fixed by suitable fixing screws 56a in through holes 56 formed therein. Cuts are provided in the fixing brackets 36 and 55 so that they are fitted by the adjusting mechanisms 37 and 58, respectively, and a through hole 46a is provided in the fixing bracket 46 so that it is fitted by the support shaft 47. It should be noted that it is also possible to fix the fastening rods with the use of through holes 56 on the right side in the direction of the vehicle width of the erected portion 31a in response to the structure of the base member 20.
    [0048] On one side of the erected portions 31a and 41a on the rear side of the vehicle body to which the attachment rods 36, 46 and 55 are attached, a plurality of second cooling fins 38 is provided. By the second cooling fins 38, the heat capacity of the cooling fins is additionally increased, and even a case in which the amount of heat generated by the LED device 60 and 70 becomes greater can be sufficiently supported. In the present modality, a heatsink is implanted by the members similar to the plate 31 and 41, cooling fins 35 and 45 and erected portions 31a and 41a.
    [0049] FIG. 5 is a perspective view of an LED unit 30a applied to a lighting unit, in accordance with a modification to the present embodiment. Symbols like those used in the preceding description denote equal or equivalent portions. The present modification is characterized in that not only the second cooling fins 38 are provided on a face on the body on a rear side of the vehicle body of the erected portion 31a of the member similar to the low beam plate 31, but also a plurality of seconds cooling fins 39 are provided on one side of the body on the front side of the vehicle of the erected portion 31a. The cooling fins 39 extend towards the front side of the vehicle body to a position close to the reflector 34 along a shape of a rear face of the reflector 34, and the cooling effect is further improved. Since a space is provided between the cooling fins 39 and the reflector 34, the heat from the cooling fins 39 is less likely to be transmitted to the reflector 34. It should also be noted that the nut bolts 54 for fixing from the reflector 34 to the member similar to the plate 31 have a heat dissipation function because they are in front of that space.
    [0050] FIG. 6 is a perspective view of an LED unit 130 for a vehicle, according to a second modification of the present embodiment. The LED unit 130 is characterized in that the cooling fins provided vertically on the board-like members overlap with each other in the upward and downward directions. According to this configuration, while a large number of cooling fins are provided on the board-like members, it is possible to increase the size of the cooling fins in the vertical direction or to reduce the size of the LED unit 130 in the vertical direction. The basic structure of the LED unit 130 is similar to that of the LED unit 30 described above, in this document together with the modality. However, the LED unit 130 in this modification is different in that, since the cooling fins 135 and 145 are formed in a relationship offset from each other in relation to the through holes for nut bolts 151, when a member similar to the low beam plate 131 and a member similar to the high beam plate 141 are opposed to each other, the cooling fins of these overlap each other in the vertical direction without maintaining contact with each other.
    [0051] The member similar to the low beam plate 131 and the member similar to the low beam plate 141 that have the same shape are fixed by the nut bolts 151 with four spacers 152 interposed between them so that they have a gap 150 among them. LED devices 160 and 170 are mounted on the member similar to the low beam plate 131 and on the member similar to the high beam plate 141, respectively. The plurality of cooling fins 135 and 145 are formed on members similar to plate 131 and 141, respectively.
    [0052] In the following, a description is provided taking the member similar to the low beam plate 131 as a representative. For the member similar to the low beam plate 131, the LED device 160 for a low beam is fixed by screws 157 and a curved reflector 134 is fixed by screws 154. The LED device 160 is configured from a panel 132 and an LED 132a, and fastening posts 136 and 146 are attached to the left end portions in the direction of the vehicle width of the erected portions 131a and 141a, respectively. The plate-like members 131 and 141 are fastened to each other by nut screws 151 with spacers 152 interposed between them. In addition, the plurality of cooling fins 135 provided on the lower face of the member similar to the low beam plate 131 and the plurality of cooling fins 145 provided on an upper face of the member similar to the high beam plate 141 extend to the interval 150 for cooling provided by the spacers 152 so that the cooling fins 135 and the cooling fins 145 are alternately arranged in the horizontal direction and overlap each other in the vertical direction. Consequently, the height dimension of the cooling fins 135 and 145 can be increased.
    [0053] FIG. 7 is a front elevation view showing an example where LED units 90L and 90R of the same structure are used in front lamps 80L and 80R of the type of two lamps left and right. The LED units, according to the present modality, are configured so that the plate-like members for a high beam and a low beam are formed in the same shape so that a common mold for casting, casting or injection is used. for them to improve productivity. Using this, the headlights 80L and 80R of the type of two lamps left and right can be configured from a member similar to the common plate 91.
    [0054] The lighting unit on the left side 80L is configured by attaching the LED unit on the left side 90L to a housing on the left side 81L that has fixing flanges 81 to the vehicle body. Similarly, the right side lighting unit 80R is configured by attaching the right side LED unit 90R to a right side housing 81R that has fixing flanges 81 to the vehicle body. In this case, the left and right LED units 90L and 90R can support any left and right housings 81L and 81R by forming the plate-like member 91 on which the cooling fins 92 are formed, an LED device 93, a reflector 94 and an erected portion 95 commonly interchangeable with the use of 96L and 96R fixing brackets attached to the erected portion 95 between LED units 90L and 90R. It is also possible for the headlights of the type of two lamps left and right to support a structure in which only the LED device 93 and the reflector 94 are made differently between the headlights so that different functions for a high beam and a low beam are for the left and right lamps.
    [0055] As described above, according to the LED lighting unit for a vehicle, according to the present invention, the LED lighting unit for a vehicle that includes two members similar to the plate on which LED devices are mounted as light sources and reflectors arranged to cover the LED devices and configured to reflect radiating light from the LED device in front of the vehicle body and in which the two plate-like members are arranged in an opposite relationship to each other with a space provided between them so that the mounting faces of the LED device are led to the outer sides, they are configured so that the cooling fins are provided on the two members similar to the board so that they extend in a relationship opposite each other towards space. Therefore, it is possible to effectively use the space between the two members similar to the plate to dissipate the heat generated by the LEDs on the back side to the mounting faces.
    [0056] It should be noted that the shape and structure of the housing and lens of the LED lighting unit, the shape and structure of the LED device and the plate-like members, the shape and the number of cooling fins , the shape and color density of the extension, the shape and structure of the reflectors, the structure of the adjustment mechanisms of the optical geometric axis and so on are not limited to those modalities. However, several changes are possible. For example, the two members similar to the plate can be arranged so that the upper side member is used for a high beam while the lower side member is used for a low beam. Or, a plate-like member and a reflector can be integrally formed, or a plate-like member and an erected portion can be configured as separate members, which are attached to each other by a fixing member.
