[Operation of headlight device 10]
In the headlight device 10 according to the present embodiment configured as described above, when the light L1 is emitted from the upper first LED light source 66a for low beam, the emitted light L1 is the upper reflector of the first reflector 70. The light is reflected forward by the reflecting portion 76a of the lens 72a. The reflected light L1 is irradiated forward through the lens 56 as low-beam irradiation light L1i. As described above, the reflecting portion 76a of the upper reflector 72a has a semicircular shape in a front view of FIG. Therefore, when the first lighting unit 50 irradiates the low beam irradiation light L1i of the upper substrate 62 by the first LED light source 66a forward, when the headlight device 10 is viewed from the front of the motorcycle 12 as shown in FIG. The irradiation light L1i can be visually recognized as the semicircular light emission on the upper inner side of the lens 56.

When the light L2 is emitted from the lower first LED light source 66b for high beam, the emitted light L2 is reflected forward by the reflecting portion 76b of the lower reflector 72b of the first reflector 70. The reflected light L2 is irradiated forward as high-beam irradiation light L2i through the lens 56. Since the reflecting portion 76b of the lower reflector 72b has a semicircular shape in a front view of FIG. 2, the first lamp portion 50 irradiates forward the irradiation light L2i of the high beam by the first LED light source 66b of the lower substrate 64. In this case, although not shown, when the headlight device 10 is viewed from the front of the motorcycle 12, the irradiation light L2i can be visually recognized as semicircular light emission on the lower side of the lens 56.

Furthermore, when the light L3 is emitted from the upper and lower second

LED light sources

68a and 68b for position light, each of the emitted light L3 is reflected by the reflection portions of the upper reflector 80a and the lower reflector 80b of the second reflector 72, respectively. It is reflected forward by 84a and 84b. In this case, a knurled portion 88 of the lens 56 is formed in front of each reflected light L3. Therefore, each light L3 reflected to the front is diffused by the knurled portion 88, and the second lighting part 52 irradiates the diffused light L3 to the front as the irradiation light L3i of the position beam. Therefore, as shown in FIG. 4, when the headlight device 10 is viewed from the front of the motorcycle 12, arc-shaped light emission in which the high beam and the low beam have different light patterns in the upper and lower contour portions of the lens 56 It is possible to visually recognize the irradiation light L3i.

[Modification of headlight device 10]

LED light sources

66 a and 66 b and the second

LED light sources

68 a and 68 b are disposed on the top surface 90 a and the bottom surface 90 b of one substrate 90 respectively. It is different.

In addition, the second LED light source 68a disposed on the top surface 90a and the second LED light source 68b disposed on the bottom surface 90b are disposed with their positions shifted in the front-rear direction. The shapes of the first reflector 70 and the second reflector 72 are also changed from the configurations of FIGS. 1 to 4 in accordance with the arrangement positions of the first

LED light sources

66a and 66b and the second

LED light sources

68a and 68b. . Also in the substrate 90, wiring (not shown) for connecting to the first

LED light sources

66a and 66b and the second

LED light sources

68a and 68b is disposed.

Also in this modification, when the light L1 is emitted from the upper first LED light source 66a for low beam as in the configuration of FIGS. 1 to 4, the first lighting unit 50 is inside the upper side of the lens 56 in the front view of FIG. Emits semicircular light. Further, when the light L2 is emitted from the lower first LED light source 66b for high beam, the first lamp part 50 emits semicircular light inward of the lower side of the lens 56. Furthermore, when the light L3 is emitted from each of the second

LED light sources

68a and 68b, the second lighting unit 52 emits substantially arc light at the upper and lower contour portions of the lens 56.

[Effect of this embodiment]

LED light sources

LED light sources

68a and 68b may be disposed on the same substrate (upper substrate 62, lower substrate 64, substrate 90) without increasing the number of substrates. it can. Thereby, the 1st lamp part 50 and the 2nd lamp part 52 can be arranged compactly. Therefore, in the headlight device 10 provided with the first light unit 50 and the second light unit 52 that emits light around the first light unit 50, the headlight device 10 having a compact arrangement can be realized. In addition, the first

LED light sources

66a and 66b and the second

LED light sources

68a and 68b are disposed on the same substrate so as to be shifted forward and backward. As a result, the first lamp unit 50 and the second lamp unit 52 are separately provided in the space 60 of the headlight device 10, and the functions in the headlight device 10 can be easily distinguished. Also, the wiring of the first

LED light sources

66a and 66b and the second

LED light sources

68a and 68b on the same substrate is facilitated.

Further, the above-described substrates (upper substrate 62, lower substrate 64 and substrate 90) are extended in the front-rear direction of the headlight device 10, and the first

LED light sources

Furthermore, since the plurality of first

LED light sources

66a and 66b direct the light L1 and L2 directed in the opposite directions, the first lamp unit 50 emits the low beam irradiation light L1i and the high beam irradiation light L2i. It can be divided and irradiated forward. As described above, by spatially dividing the function of the first lamp unit 50 in the headlight device 10, a headlight lamp having a simple structure can be realized.

Further, using the first reflector 70, the space 60 of the headlight device 10 is divided into a space in which the first

LED light sources

66a and 66b are disposed and a space in which the second

LED light sources

68a and 68b are disposed. Thus, the lights L1 and L2 from the first

LED light sources

66a and 66b and the light L3 from the second

LED light sources

68a and 68b can be individually irradiated to the front of the headlight device 10. In addition, since the shape of a simple reflector can be realized, a compact and thin lamp can be realized.

Furthermore, since the

front end portions
