Abstract
A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer located over 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, a frame located on the base board, the chip mounted on the base board, a transparent material layer located between the wavelength converting layer and a side surface of the chip so as to extend toward the wavelength converting layer, and a reflective material layer disposed at least between the frame and both side surfaces of the wavelength converting layer and the transparent material layer. The semiconductor light-emitting device can be configured to improve light-emitting efficiency of the chip by using the reflective material layer as a reflector, and therefore can emit a wavelength-converted light having a high light-emitting efficiency from a small light-emitting surface.
