ABSTRACT:
The present invention is a method for obtaining a better color rendering with a photoluminescence plate, and the better color rendering is obtained by using UV radiating on the photoluminescence plate stacked with a red photoluminescence plate, a green photoluminescence plate and a blue photoluminescence plate. Therefore, the color rendering is above 90% and close to the solar light. The photoluminescence plate can be made from directly coated with photoluminescence layers of three colors or with fully mixed fluorescent materials of three colors. Consequently, a white light relied on the present invention is more uniform than the conventional techniques with a color mixing performance based on tricolor LEDs.
