Abstract
A light emitting component, and more particularly to a white light emitting component with high light emitting efficiency are provided. The white light emitting component with high light emitting efficiency has properties of high driving voltage, high color render index and concentrated optical density. The light emitting component includes a plurality of different light emitting diode chip groups for emitting a number of lights in different wavelength ranges and a wavelength conversion fluorescent material. A manufacturing method by stacking miniature light emitting diode chip groups to form the white light emitting component is also provided.
