| 20110317283 | LED LIGHT CONVERTING RESIN COMPOSITION AND LED MEMBER USING THE SAME - Disclosed are an LED light converting resin composition, and an LED member using the same. The LED light converting resin composition comprises 20˜99 wt % of transparent resin, 0.8˜60 wt % of a lighting color converting fluorescent substance, and 0.2˜20 wt % of a light diffusing bead with an average particle diameter of 0.2˜30 μm. It is possible to emit a white or yellowish white light, like a conventional white light LED, only by independently using a white light emitting LED lens with no change in a blue, violet, or UV LED. There is no need to use a white LED which is relatively expensive and has a short life. Instead, as required, it is possible to easily replace a conventional LED lens with the disclosed LED lens by a user or an operator, thereby obtaining a mild white light with a required luminance. Thus, glaring, caused by a high-luminance white LED lighting, can be effectively reduced, thereby providing a milder lighting with improved comfort. Furthermore, the concern about the deterioration of a lighting device can be reduced due to a high heat-resistance, which increases economical efficiency. | 12-29-2011 |
