Abstract
Official abstract text for this publication.
A white light emitting device (LED) and a manufacturing method thereof wherein an LED coated with polymeric resin in which organic phosphors are solved dissolved and inorganic phosphors are dispersed creates a white LED, thereby producing an effect of excellent luminance and color coordinate without creating a compatibility problem with the polymeric resin. The present invention creates a white LED with a high luminance and a long service life using polymeric composition containing organic and inorganic phosphors, organic and inorganic combined phosphors and organosilicates, and an epoch making improvement in terms of luminance and credibility without additional process added to an existing element fabricating process, thereby enabling to achieve price competitiveness through cost reduction.
First claim
Opening claim text (preview).
The invention claimed is: 1. A white light emitting device, the device comprising: a light emitting diode (LED); and a polymer resin encompassing the LED, wherein the polymer resin comprises organic phosphors, inorganic phosphors, and organosilicates, wherein the organic phosphors are dissolved in the polymer resin and particles of both the inorganic phosphors and the organosilicates are dispersed in the polymer resin, wherein each of the organosilicates has porous channels for containing each of the inorganic phosphors therein, and wherein the weight of the inorganic phosphors is 2˜9 wt % while the weight of the organic phosphors is 0.0001˜0.01 wt % out of the total weight of the polymer resin. 2. The device of claim 1 , wherein the organosilicates are in the range of 1˜30 wt % out of the total weight of the polymer resin that comprises the organic phosphors and the inorganic phosphors. 3. The device of claim 1 , wherein the organosilicates are in the range of 5˜15 wt % out of the total weight of the polymer resin that comprises the organic phosphors and the inorganic phosphors. 4. The device of claim 1 , wherein the LED is a blue LED or an ultraviolet (UV) LED. 5. The device of claim 1 , wherein a surface of the polymer resin takes a shape of any one of a convex lens, a planar shape, or a concave lens.
