Patent ID: 7635870

Claim:
A light emitting diode (LED) packaging structure, comprising: a package body having an accommodating room; an LED chipset disposed in the accommodating room, comprising: a first LED chip to generate a green light having a wavelength about 510 nm to 550 nm; a second LED chip to generate a blue light having a wavelength about 440 nm to 480 nm; and a third LED chip to generate a red light having a wavelength about 600 nm to 630 nm; a package material disposed in the accommodating room to protect the LED chipset; and a phosphor mixed in the packing material and able to generate a light with a wavelength about 560 nm to 600 nm, wherein the green light, the blue light and the red light are mixed to form a white light, and the blue light further excites the phosphor to generate the light with the wavelength about 560 nm to 600 nm for mixing with the blue light to further form an additional white light.
