Bulb형 LED Lamp를 위한 조명 광학계 설계

Abstract

Illumination optical system designed for LED light bulb which emits light in all directions was simulated with satisfactory for Energy star standards. Components of the optical system, LED light source, the cover of the LED bulb, reflector, which is to confirm the diffuser plate, LightTools Software was used to design the illumination optics. The main point of the secondary optical system design, the location of the LED light source, the shape of the cover LED bulb, the location of the reflection plate, and the scattering properties of the diffusing plate. To a confidence that the simulation must measure the characteristics of the Components. So had measured Opical properies of the LED light source, the cover shape of the LED bulb, Scattering properties of the diffuser plate. Mechanism of the LED bulb which emits light in all directions is reflected on the reflection plate which is coated on the light cover from the inside and is emitted from the light source is moving in the back ward reflected light is scattered by the diffuser plate. LED bulb has been designed to satisfy the standard light distribution and color specifications of the Energy star.
