PURPOSE: A light diffusion plate composition of an LED lamp is provided to simultaneously secure the dispersibility and penetrability of light from an LED light source due to glass fiber included in a light diffusion plate by forming the light diffusion plate with polycarbonate and glass fiber. CONSTITUTION: An LED module includes a printed circuit board with LEDs. A housing combines a combination part formed in the LED module. An LED lamp is composed of a light diffusion plate(40) diffusely reflecting an LED light source. The light diffusion plate is composed of polycarbonate(41), and glass fiber(42). The mixture composition ratio of the light diffusion plate is composed of 70-90 weight% of the polycarbonate and 5-30 weigh% of the glass fiber. |
