SEMICONDUCTOR LIGHT-EMITTING DEVICE AND MANUFACTURING METHOD |
摘要 |
A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer located on at least one semiconductor light-emitting chip in order to emit various colored lights including white light. The semiconductor light-emitting device can include a base board, the chip mounted on the base board and a transparent plate disposed on the wavelength converting layer including a spacer and a phosphor having a high density. The wavelength converting layer can be formed in a thin uniform thickness between the transparent plate and a top surface of the chip using the spacer so as to extend toward the transparent plate. The semiconductor light-emitting device can be configured to improve light-emitting efficiency of the chip by using the thin wavelength converting layer including the phosphor having a high density, and therefore can emit a wavelength-converted light having a high light-emitting efficiency from a small light-emitting surface. |
