Abstract
A light-mixing type light-emitting apparatus comprises a plurality of light-emitting diodes (LEDs) formed on a transparent carrier, wherein each of the LEDs with a transparent substrate emits light of a distinct color when driven, and the light beams generated from the LEDs are mixed to form a specific color. The transparent carrier setting forth in the present invention provides a mixing zone underlying the plurality of LEDs for the light beams to mix uniformly so as to improve the light-mixing efficiency of the light-emitting apparatus and shorten the mixing distance.
