Patent abstract

White-light emitting devices and methods for manufacturing the same. The white-light emitting device emits white light comprising a first color component with first wavelength, a second color component with a second wavelength, and a third color component with a third wavelength. The first wavelength is shorter than the second wavelength. The second wavelength is shorter than the third wavelength. The white-light emitting device comprises a baseboard. A first light emitting device emitting the first color component and a second light emitting device emitting a second color component are disposed on the baseboard. A transparent passivation layer with a substantially planar surface is formed on the baseboard. A second light emitting device is disposed on the transparent passivation layer. The second light emitting device emits the third color component which is responsive to the first and the second color components.
