PROBLEM TO BE SOLVED: To eliminate adhered snow or ice even in a state with the snow or ice adhered in a light emission device.SOLUTION: The light emission device comprises: a protection cover 10 (cover) that has translucency; an electronic circuit 20 (circuit) in which thirty six LED elements 22 (light emission body) and three drive components 25 (high heating body) larger in a heat transmission than the LED element 22 are mounted on a mount face 21a (the other face) side, and which has a wiring face 21b (one face) provided in contact with an inner face 10b of the protection cover 10; and a reflector 80 (reflection member) that reflects light L emergent from the LED element 22 to a protection cover 10 side. Thirty six LED elements 22 are arranged to be distributed in an area (specific area) across an almost entire face of the inner face 10b of the protection cover 10, and three drive components 25 are arranged concentratively in an area 10d (small area) at a low part smaller than the area having the LED element 22 distributed. |
