2g) is housed in the lamp housing 3, and the lens plate 3 for transmitting the light of the LED 1 in the lamp housing 3 to the outside.
b is formed into a curved surface. In this case, since the lens plate 3b is formed in a curved surface, the housing main body 3a is formed in a stepped shape in accordance with the curved surface, and the divided LED boards 2a to 2g are arranged on each step of the step. Thus, the lens cut portions 4 formed on the lens plate 3b and the LEDs 1 are set so as to be at equal intervals. By setting the lens cut portions 4 and the LEDs 1 at equal intervals in this manner, it is possible to prevent unevenness in the brightness of the lens surface and improve the appearance.

面倒が少ない。According to the invention of claim 8, the LED substrate can be manufactured as it is by the conventional manufacturing process. In addition, since the LED frame is bent after fitting the metal frame to both side edges of the LED substrate, an excessive force is less likely to be applied to the LED substrate, and the bent shape of the LED substrate can be held at a predetermined angle. . Therefore, the LED substrate can be fixed in an appropriate posture along the lens plate. Further, even when the LED substrate is completely divided by bending, the LED substrate portions divided by the metal frame can be connected to each other, so that there is little trouble in mounting.
