Abstract: A light source and corresponding method of manufacturing are provided. The light source includes a base. A first light-emitting element is disposed on the base and emits first emission light having a first spectrum. A second light-emitting element is disposed on the base adjacent to the first light-emitting element. The second light-emitting element emits second emission light having a second spectrum different from the first spectrum. A reflector is disposed between the first light-emitting element and the second light-emitting element. The reflector reflects, among components of the first emission light, a component of the first emission light that travels toward the second light-emitting element.

Abstract: Provided is a light source that emits white light having a correlated color temperature of at least 2700 K and at most 7200 K, a chromaticity deviation within ±10, and an average color rendering index of at least 80. The light source includes: a solid-state light emitter that emits light of a first wavelength, and a fluorescent layer. The fluorescent layer receives light from the solid-state light emitter, and transmits light having a second wavelength after being excited by the light from the solid-state light emitter. The fluorescent layer includes: fluorescent materials of two or more types different in emission peak wavelength, a binder that includes a light-transmissive inorganic compound that fixes the fluorescent materials, and a void that is provided between the fluorescent materials.

Abstract: A joint structure and a manufacturing method thereof are provided which can improve heat dissipation properties and which can inhibit damages. A joint structure includes: an insulating substrate and a heat dissipation substrate; a first silver particle layer that is joined to the insulating substrate and that includes a plurality of first silver nanoparticles which are joined; a second silver particle layer that is joined to the heat dissipation substrate and that includes a plurality of second silver nanoparticles which are joined; and a copper particle layer that interposes the first silver particle layer and the second silver particle layer, that is joined to the first silver particle layer and the second silver particle layer, and that includes a plurality of copper nanoparticles which are joined. A particle size of the copper nanoparticles is larger than particle size of both the first silver nanoparticles and the second silver nanoparticles.
