PURPOSE: An LED lamp is provided to good dielectric voltage withstanding property by forming 3mm or more separation portions between a heat sink and a main body. CONSTITUTION: A heat resistance and thermal conductive resin main body(3) accept a PCB(Printed Circuit Board)(8) and a heat sink(7). The heat sink includes a thermal conductive insulating layer(7a) in the upper side of the PCB. A lamp holder(2) is plated with a nickel while being arranged in the upper end of the main body. A light diffusion cover(6) is arranged in the lower end of the main body. A separation portion(7b) is formed between the end part of the heat sink and the inner circumference of main body. |
