PURPOSE: An LED lamp for nuclear plant is provided to surround a power supply unit with a shielding member, thereby preventing damage of the power supply unit caused by radiation. CONSTITUTION: A main body(110) of a hollow shape comprises a plurality of insertion units. The main body comprises a mounting hole(117) in an inside. A plurality of radiant heat plates(120) is inserted into an insertion unit. An LED module(130) is mounted in a lower unit of the main body. A power supply unit(140) is inserted into the mounting hole. The power supply unit supplies power to the LED module. A shielding member(150) surrounds the power supply unit and is inserted into the mounting hole. The main body and a radiant heat plate are composed of copper coated aluminum. The shielding member prevents that radiation is penetrated into the power supply unit. |
