Abstract
A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer encapsulating 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, the wavelength converting layer formed around the chip, a transparent plate located on the wavelength converting layer and a diffusing reflection member disposed between the frame and both side surfaces of the wavelength converting layer and the transparent plate. The device can be configured to improve the linearity of a boundary between the diffusing reflection member and both side surfaces by using the transparent plate, and therefore can be used for a headlight that can form a favorable horizontal cut-off line corresponding to the boundary via a projector lens without a shade.
