PURPOSE: An LED illumination lamp is provided to effectively emit internal heat outside by using a light diffusion pipe and the combining protrusion of a side cap. CONSTITUTION: In an LED illumination lamp, a light diffusion pipe(110) diffuses the light to outside. An LED(120) radiates the light to outside. A metal circuit board(130) forms a circuit for supplying power to the LED. The side cap(140) is combined with the both ends of the light diffusion pipe and supplies external power to inside. The light diffusion pipe forms a plurality of fine holes for emitting heat. The light diffusion pipe has a protrusion groove(111) which is combined with the side cap. The side cap has the protrusion groove corresponding to the protrusion groove. The side cap is that the jamming protrusion(141) is formed in the location corresponding to the barrier groove. |
