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 in order to emit various colored lights including white light. The device can include a board, a frame located on the board, at least one light-emitting chip mounted on the board, the wavelength converting layer located between an optical plate and an outside surface of the chips so that a density of a peripheral region is lower than that of a middle region, and a reflective material layer disposed at least between the frame and a side surface of the wavelength-converting layer. The device can have the reflective material layer form each reflector and can use a wavelength converting layer having different densities, and therefore can emit a wavelength-converted light having a high light-emitting efficiency and a uniform color tone from various small light-emitting surfaces. |
