Furthermore, since the plurality of first LED light sources 66a and 66b emit light L1 and L2 directed in different directions from each other, and the plurality of second LED light sources 68a and 68b emit light L3 directed in different directions from each other, the headlight device 10 can The irradiation lights L1i to L3i irradiated forward are uniformized.

In addition, since the plurality of first LED light sources 66a, 66b emit light L1, L2 directed in opposite directions to each other, the first lamp part 50 can be divided into the irradiation light L1i for low beam and the irradiation light L2i for high beam, and the Irradiate from the front. In this way, by dividing the function of the first lighting unit 50 by space in the headlight device 10 , it is possible to realize a lamp body for a headlight with a simple structure.

In addition, by using the first reflector 70 to divide the space 60 of the headlight device 10 into a space for arranging the first LED light sources 66a and 66b and a space for arranging the second LED light sources 68a and 68b, the first LED light sources 68a and 68b can be The light L1 and L2 of the light sources 66a and 66b and the light L3 from the second LED light sources 68a and 68b are individually irradiated to the front of the headlight device 10 . In addition, since the shape of the reflector can be simplified, a compact and thin lamp body can be realized.

Furthermore, since the front end portions 86a and 86b of the second reflector 72 are located on the outer side in the vertical direction from the front end portions 78a and 78b of the first reflector 70 , the first reflector 70 can reliably transmit the light from the first LED light source. The lights L1 and L2 of the 66a and 66b are reflected (irradiated) forward, and the light L3 from the second LED light sources 68a and 68b is reliably reflected (irradiated) forward by the second reflector 72 without using a light guide lens and other light guide components.

In addition, as shown in the configuration of FIGS. 1 to 3 , since the two upper substrates 62 and the lower substrate 64 are arranged to face each other with a gap therebetween, the LED light sources (the first LED light sources 66a, 66b, the second LED The light sources 68a, 68b) are arranged at the same positions in the front-rear direction on the upper substrate 62 and the lower substrate 64. Thereby, the 1st LED light sources 66a, 66b and the 2nd LED light sources 68a, 68b can be arrange|positioned compactly.

5 and 6 , on one substrate 90, the first LED light sources 66a, 66b and the second LED light sources 68a, 68b are arranged on the substrate extending in the front-rear direction so as to be displaced in the front-rear direction. Since the upper surface 90a and the bottom surface 90b of the 90 are used, the first LED light sources 66a and 66b and the second LED light sources 68a and 68b can be compactly arranged using both surfaces of the single substrate 90 .
