Abstract: A light emission apparatus includes: an electrode; a LED mounted on the electrode with an indium layer interposed therebetween, the LED having a substrate formed of an n-type ZnSe single crystal, and an epitaxial light emission structure formed of a compound crystal comprising ZnSe serving as a matrix, the epitaxial light emission structure being provided on the substrate and emitting light when an electric current is introduced thereinto; and resin encapsulating the LED, the resin having a glass transition temperature of lower than 80 degrees centigrade or being soft to be still elastic in a vicinity of the LED at room temperature.

Abstract: The present invention provide a light emitting device including: a resin base having a patterned interconnection; an n-type ZnSe substrate mounted on the resin base; an epitaxial light emission structure formed of a compound crystal relating to ZnSe serving as a matrix, formed on the ZnSe substrate and emitting light when an electric current is applied. A reflector is so constructed and positioned that a spatial distribution of the light emission intensity of the fluorescence light approximates the light emission intensity of the epitaxial light emission structure. The fluorescence light is produced in the ZnSe substrate excited by with the light emission from the epitaxial light emission structure.

Abstract: In a light-emitting diode, a phosphor layer 6 containing a phosphor is laid on top of translucent sealing resin 8 having a light-emitting diode element 3 sealed in it, and then, by shaving the phosphor layer 6, the hue of the light emitted by the light-emitting diode is adjusted. This makes it possible to adjust the hue of the light emitted by individual light-emitting diodes to obtain a uniform hue. For quick and easy adjustment of the hue, the phosphor layer 6 is shaved preferably by laser beam machining.

Abstract: An illumination light guide includes a plurality of elongated illuminating portions; a light guiding path portion connecting one end of each of the illuminating portions; a light receiving portion formed in the light guiding path portion; a plurality of light distributing/reflecting portions formed in the light guiding path portion so as to correspond to the illuminating portions and having different lengths such that the longer a distance from the light receiving portion to one of the light distributing/reflecting portions, the longer a length of the one of the light distributing/reflecting portions; and a plurality of light reflecting portions formed at the other ends of the illuminating portions, respectively. With this structure, the light emitted from a single light source is received by the light receiving portion, and is uniformly distributed and reflected by the light distributing/reflecting portions and transmitted into the respective illuminating portions.
