PROBLEM TO BE SOLVED: To reduce cost by simplifying processing of a radiator and a shape of an LED substrate, and to prevent the LED from being damaged easily.SOLUTION: A radiator unit 3 is formed by a radiator 30, LEDs 51 and an LED substrate 50 in which the LEDs 51 are mounted. The LED substrate 50 side of the radiator unit 3 is inclined obliquely downward, and a front surface of the radiator unit 3 and the LED substrate 50 are flat shaped. Openings 61 for exposing the LEDs 51 are bored in a cover 60. A recessed part 62 expanding outward is formed at a circumferential edge of the opening 61. The thickness of the opening 61 is formed to be thinner than the thickness of the cover 60, and a head part of the LED 51 does not protrude from the surface of the cover 60. The lower the recessed part 62 is located, the larger the lower edge portion of the opening edge of the recessed part 62 extends. |
