Abstract: A method for manufacturing a semiconductor light-emitting device includes: forming a plurality of guide grooves so as to be depressed from a surface of a semiconductor structure layer toward a semiconductor substrate and to align and extend along a direction perpendicular to an extending direction of a plurality of line electrodes; forming, in each of the plurality of guide grooves, a scribe groove so as to be depressed from a bottom surface of the guide groove toward the semiconductor substrate and to extend along an extending direction of the guide groove; and dividing a semiconductor wafer along the plurality of guide grooves. The guide groove and the scribe groove are formed to have end shapes in such a manner that inner walls thereof project toward each other in the extending direction of the scribe groove.

Abstract: A vehicle lighting fixture can eliminate the use of a phosphor member that causes the reduced color rendering properties and the occurrence of color separation, specifically, can enhance the color rendering properties and suppress the occurrence of color separation more than a conventional white light source that use a semiconductor light emitting element such as an LD and a phosphor member (wavelength converting member). The vehicle lighting fixture includes: a supercontinuum light source configured to output supercontinuum light containing light in a visible wavelength region, and an optical system configured to control the supercontinuum light output from the supercontinuum light source.

Abstract: A vehicular lighting device from which a fluorescent material is omitted that may cause deterioration of color rendering properties and occurrence of color separation is provided. The vehicular lighting device can have higher in color rendering properties than a conventional white light source obtained by combining a semiconductor light-emitting element such as an LD and the fluorescent material (wavelength converting member) and can suppress occurrence of color separation. A vehicular lighting device of the presently disclosed subject matter includes a supercontinuum light source that outputs supercontinuum light containing a visible wavelength region, and an optical system that controls the supercontinuum light output by the supercontinuum light source.
