摘要： A light-emitting device includes: a light guide that includes (i) a light-transmissive member that is light-transmissive at least in a visible light region and (ii) a light control layer that is disposed on at least a part of a surface of the light-transmissive member; and a light source that emits light toward at least one end surface of the light-transmissive member. The light control layer has reflected-wavelength selectivity that makes a wavelength of reflected light dependent on an incident angle of incident light.

摘要： Three light-emitting units are included. Two light-emitting units of the three light-emitting units are similar-color light-emitting units that emit light in a similar color, and have mutually different luminance lives. A remaining light-emitting unit of the three light-emitting units is a different-color light-emitting unit that emits light in a color that is different from the similar color, and has a luminance life that is shorter than each luminance life of the two similar-color light-emitting units.

摘要： A lighting apparatus includes a laser that emits laser light. A transmission component transmits the laser light. The laser light transmitted by the transmission component enters and is emitted by an optical connector. A wavelength converter emits wavelength-converted light according to the laser light emitted from the optical connector. A lens causes the laser light emitted from the optical connector to enter the wavelength converter. A luminaire emits the wavelength-converted light. The luminaire includes a holder that removably holds the optical connector. The optical connector includes: an optical component that is light-transmissive, mixes the laser light that enters, and emits the mixed laser light; and a case that has a light-blocking property and houses the optical component and part of the transmission component. The lens is in an optical path from the optical connector to the wavelength converter.

摘要： A lighting device includes a laser light source that emits laser light, a wavelength converter that converts a wavelength of the laser light and emits wavelength-converted light, and a linear light guide that is elongated and guides the wavelength-converted light emitted by the wavelength converter and introduced through a longitudinal end surface. The linear light guide includes a lateral surface that emits the wavelength-converted light guided by the linear light guide. A proportion of the wavelength-converted light emitted by the lateral surface gradually increases with an increase in optical path length in the linear light guide.

摘要： An organic electroluminescent element includes at least one light emitting layer, a high refractive index layer (first layer), and a low refractive index layer (second layer). An uneven structure including a plurality of protrusions each having two or more steps is provided at an interface between the high refractive index layer and the low refractive index layer. The organic electroluminescent element includes a protective layer. The protective layer is a layer disposed between the second layer (low refractive index layer) and a light-exiting surface of the organic electroluminescent element or is the second layer (low refractive index layer).
