PROBLEM TO BE SOLVED: To provide an LED lamp which reduces a manufacturing cost and reduces weight by decreasing metal working as much as possible and decreasing the number of forming components as much as possible.SOLUTION: An LED lamp includes: a lighting metal substrate 20 of strip shape, on the upper surface of which a plurality of LED light sources 21 are mounted; a cylindrical lamp cover 1 which houses the lighting substrate, is subjected to light-diffusion treatment and has translucent property; and a sleeve 10 in which lamp pins 14 to be attached to both sides of the lamp cover are projected. The lighting substrate is held between bottom part projection bodies 3, 3 projected from the bottom part as non-light emitting side of the lamp cover and a pair of lateral part projection bodies 2, 2 projected from left and right inner walls of the upper side of the bottom part projection bodies and, on the light emitting side of the upper side of the lighting substrate, an inner wall surface of the lamp cover in the angle range of at least 220° or more remains. |
