Abstract: 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.

Abstract: The disclosure relates to an organic electroluminescence element including an organic layer including multiple light-emitting layers. The light-emitting layers include a blue light-emitting layer including a blue light-emitting dopant. In a case where emission color of the organic electroluminescence element operated at an operation temperature for a stable state is represented in a CIE1931 chromaticity coordinate system, when coordinate point A of the emission color at an early stage of use and coordinate point B of the emission color deteriorated by use are represented by (x1, y1) and (x2, y2) respectively, a relation of y2≧y1 is satisfied. When amounts of changes in x and y values from coordinate point A to coordinate point B are represented by equations of Δx=x2−x1 and Δy=y2−y1 respectively, a relation of Δy≧Δx is satisfied. It can be made difficult to perceive change in emission color and lifetime can be prolonged

Abstract: An illuminating device according to the present disclosure is of a reflective type and uses a laser beam. The illuminating device includes: a laser element that emits a laser beam; an optical fiber that transmits the laser beam emitted by the laser element; a phosphor layer that converts a wavelength of light incident on one of surfaces and emits the light through the one of the surfaces; and an optical component that causes reflected light of the laser beam transmitted through the optical fiber to be incident on the one of the surfaces of the phosphor layer. With the illuminating device, an intensity distribution of the light incident on the one of the surfaces of the phosphor layer is sparse at a central region.
