"LED 램프 확산판용 유백색유리 조성" { the Glass Composition for LED Lamp Diffuser Cover }은 현재 널리 사용되고 있는 LED 조명의 빛 확산 및 눈부심 방지용 폴리카보네이트(polycarbonate) 혹은 백색 코팅유리 대신 LED 조명 확산판으 로 장착하여 LED 조명 용도에 따라 적합하게 사용한다. 본 발명으로 인하여 그 동안 보급하고 있는 LED 조명 제품의 품질은 LED 패키지 수명이 다 할 때까지 커버로 인한 문제점을 말끔히 해소하고 LED 조명 용도에 맞게 커버를 장착할 수 있게 되었다."Glass Composition for LED Lamp Diffuser Plate" is a LED light diffuser for LED diffuse and anti-glare polycarbonate or white coated glass, It is suitably used according to lighting purpose. Due to the present invention, the quality of the LED lighting product that has been spreading over the past has completely solved the problems caused by the cover until the lifetime of the LED package has come to an end, and the cover can be fitted to the LED lighting application.

조명용으로 사용하는 LED 는 빛의 직진성 때문에 빛을 확산시키고, 눈부심을 방지하게 하는 확산판이 필요하다. LED 조명은 현재 에너지 절약 차원에서 세계적으로 급속하게 확산 되고 있고, LED 패키지 기술 또한 급속하게 발전하여 20 년 이상 사용할 수 있게 되었으나 확산판의 수명이 제한적이어서 많은 문제점을 야기하고 있었다. 본 발명으로 인하여 LED 조명에 맞춘 경제적이면서 제반 기능을 갖춘 반영구적 확산판(diffuser)을 제공하여 고품질 LED 조명 확산에 기여할 것이다.LEDs used for lighting need diffusers to diffuse light and prevent glare due to the straightness of light. Currently, LED lighting is spreading rapidly in the world in terms of energy conservation and LED package technology has been rapidly developed and used for more than 20 years. However, since the life of the diffusion plate is limited, it causes many problems. The present invention will contribute to the diffusion of high-quality LED illumination by providing a semi-permanent diffuser which is economical to the LED illumination and has various functions.
