| 20090321761 | COATING FOR CONVERTING OPTICAL SPECTRUM AND LED CHIP PACKAGE MODULE USING THE SAME - A coating for converting optical spectrum includes: a transparent colloid layer and an emitter material unit. The emitter material unit is used to convert one part of a short-wavelength band of a light source into a long-wavelength band. The emitter material unit has at least one first emitter body and at least one second emitter body both mixed with the transparent colloid layer, the at least one first emitter body is an inorganic silicate compound, and the at least one second emitter body is aan organic dye. Hence, the color rendering index (CRI) and the range of color temperature of white light generated by an LED chip package module using the coating are increased according to the function of the emitter material unit for converting one part of a short-wavelength band of a light source into a long-wavelength band. | 12-31-2009 |
