摘要： A light emitting apparatus at least includes a circuit board, several light emitting diodes (LEDs), a first reflective substance, and a diffusion structure. The LEDs, including red (R), green (G), and blue (B) LEDs, are disposed on the circuit board and connected therewith, and the first reflective substance is disposed on the circuit board and having a plurality of cavities for the LEDs. The diffusion structure is disposed on the circuit board and covering the LEDs. The diffusion structure includes several indentations, a transparent main body and several diffusion beads. The indentations are formed on a bottom surface of the diffusion structure and face the LEDs to accommodate the LEDs. The diffusion beads are dispersed in the transparent main body and diffuse light emitted from the LEDs so that light emitted from R/G/B LEDs can be mixed into white light more sufficiently through the diffusion structure.
