    摘要： A light-emitting device includes a light-emitting element emitting primary light and a wavelength conversion portion absorbing a part of the primary light and emitting secondary light having a wavelength equal to or longer than the wavelength of the primary light. The wavelength conversion portion includes a plurality of green or yellow light-emitting phosphors and a plurality of red light-emitting phosphors. The green or yellow light-emitting phosphor is implemented by at least one selected from a specific europium (II)-activated silicate phosphor (A-1) and a specific cerium (III)-activated silicate phosphor (A-2). The red light-emitting phosphor is implemented by a specific europium (II)-activated nitride phosphor (B). The light-emitting device emitting white light at efficiency and color rendering property higher than in a conventional example can thus be provided.

    摘要： An electronic equipment includes a light source, in which light of the light source is guided and emitted from an operation member having translucent properties via an optical waveguide, wherein a phosphor emitting visible light by being excited by the light from the light source is contained in a path through which the light of the light source is guided. A backlight structure in which a light source is provided in a printed substrate that is inside a casing having a waveguide plate, and light of the light source is transmitted through the waveguide plate and emitted, wherein a wavelength-converting phosphor that emits light by being excited by the light of the light source is provided in a waveguide path leading to a point where the light of the light source is transmitted through the waveguide plate and is emitted out, except the light source and the printed substrate.

    摘要： Disclosed is a light-emitting device including a light-emitting element emitting primary light, and a light converter absorbing a part of the primary light emitted from the light-emitting element and emitting secondary light having a longer wavelength than the primary light. The light converter contains a green light-emitting phosphor and a red light-emitting phosphor. The green light-emitting phosphor is composed of at least one phosphor selected from a divalent europium-activated oxynitride phosphor substantially represented by the following formula: EuaSibAlcOdNe and a divalent europium-activated silicate phosphor substantially represented by the following formula: 2(Ba1-f-gMIfEug)O.SiO2, while the red light-emitting phosphor is composed of at least one phosphor selected from tetravalent manganese-activated fluoro-tetravalent metalate phosphors substantially represented by the following formulae: MII2(MIII1-hMnh)F6 and/or MIV(MIII1-hMnh)F6. Consequently, the light-emitting device has excellent color gamut (NTSC ratio).
