ABSTRACT:
A light emitting diode packaging structure includes a package body, a red LED chip, a blue LED chip, a green LED chip, a package material and a yellow phosphor. Three LED chips are disposed within an accommodating room of the body package and covered by the package material. The yellow phosphor is uniformly mixed with the package material. A white light is formed by a mix of three types of light from the LED chips. Additionally, a yellow light which is generated from the excitement of the yellow phosphor with the blue light is mixed with a part of the blue light to further form the white light.
