PURPOSE: An LED lamp apparatus for a reactor containment building in a nuclear power plant is provided to reduce radiating ray waste, to save energy and to enhance stability of a nuclear reactor. CONSTITUTION: A base cap(9) is coupled to a spiral base(10) and installs a power supply inside. A cylindrical main body(7) is coupled to a lower end of the base cap and forms joint grooves(14) equidistantly. A holder(6) is coupled to a lower end of the cylindrical body, forms an elongated groove(13) so that a heat dissipation board(15) is coupled on the same line as the joint groove. A heat dissipation body(5), coupled to each elongated groove formed in the holder, fixed along the joint grooves, collects heat from the heat dissipation boards and discharges the collected heat. |
