ABSTRACT:
A white light emitting diode package structure having a silicon substrate is disclosed. The white light emitting diode package structure comprises a silicon substrate having a plurality of cup-structures thereon, one of a plurality of blue light emitting diodes is respectively disposed in each cup-structure, and a phosphor structure covering the silicon substrate and the cup-structures. The blue light emitting diodes have various wavelengths and the phosphor structure has a plurality of kinds of phosphor powders and a sealing material. Each kind of phosphor powder is able to convert blue light within a certain wavelength into yellow light.
