摘要： A reliable semiconductor light-emitting apparatus including an optical fiber and a wavelength converting layer and a headlight using the semiconductor light-emitting apparatus can include a ferrule holder attaching the wavelength converting layer. The ferrule holder can also attach a first ferrule covering the optical fiber, which transmits light emitted from a semiconductor light-emitting chip toward the wavelength converting layer. When the light-emitting apparatus is used for the headlight, the apparatus can be easily incorporated into a prescribed position of the headlight with confidence via a lamp holder. Thus, the disclosed subject matter can provide reliable semiconductor light-emitting apparatuses having a high radiating efficiency that can emit various color lights including a substantially white color tone having favorable optical characteristics, which can be used for general lighting, a street light, stage lighting and the like, and which can be used for the headlight that can provide a favorable light distribution pattern.

摘要： A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer located over a semiconductor epitaxial layer in order to emit various colored-lights including white light. The light-emitting device can include a semiconductor chip substrate configured not to transmit light emitted from the epitaxial layer and mounted on a mounting board, and a transparent resin layer located between the wavelength converting layer and the epitaxial layer mounted on the semiconductor chip substrate so as to extend from a side surface of the wavelength converting layer towards a substantially edge portion of the semiconductor chip substrate. The semiconductor light-emitting device can be configured to improve a color variability of a mixture light emitted from the device by using the transparent resin layer and the wavelength converting layer, and therefore can emit the mixture light having a substantially uniform color tone from a small light-emitting surface.
