Negative phototropism structure device to double efficiency of LED lamp

摘要

PURPOSE: A light distribution structure device for doubling efficiency of an LED lamp is provided to crossly diffuse a proceeding direction of light in vertical direction or diagonal direction, thereby unifying brightness of road surfaces. CONSTITUTION: A radiating plate(3) is slopingly bent inside an LED-mounted security lamp(100). Both ends of the radiating plate are in symmetrical shape. When a lamp(10) emits light, the light is crossly diffused in vertical direction and in inclined right and left directions. More than one lamp is individually arranged on an upper side and right/left sides of the radiating plate. The lamp is inserted inside while a lower part of the lamp is opened. A glove(5) opens/closes the opened lower part to diffuse the emitted light as protecting the lamp.
