PROBLEM TO BE SOLVED: To provide an LED lamp which can solve a disconnection problem caused by positional deviation of a power source substrate, while suppressing increase in cost, and which does not damage a heat radiation function of a housing.SOLUTION: An LED lamp has an appearance of a cylindrical shape comprising a housing 2 and a translucent cover 3 having a cylindrical shape and in which a cross section is a semicircular shape. On the outside of a flat part 32 of the housing 2, an LED substrate 11 on which a plurality of LEDs 12 are mounted is fixed, and on the inside, a power source substrate 7 is installed. At the flat part 32, ribs 31a and 31b are formed integrally, and the power source substrate 7 is accommodated in a recess 30 partitioned by the ribs 31a and 31b. Positional deviation in a width direction is prevented in the power source substrate 7, and disconnection of lead wires 13a and 13b is prevented. |
