Abstract: A lighting apparatus that irradiates light on a vehicle is provided. The lighting apparatus includes: a first light source that emits light for illuminating a predetermined area; a memory that stores location information indicating a location of the lighting apparatus; a second light source that outputs, to the predetermined area, a light signal indicating the location information; and a first controller that controls the first light source and the second light source, and modulates the light signal output by the second light source, in accordance with the location information stored in the memory.

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 light-emitting apparatus includes: a flexible base body; and a light-emitting component which is attached to the base body, has a form which changes flexibly following a change in the firm of the base body, and includes: a light guide which guides laser light that enters one end of the light guide; a leaking means for causing part of the laser light guided by the light guide to leak out of the light guide in a direction which crosses a light-guiding direction; and a first light-emitter which extends along the light-guiding direction and emits light based on the part of the laser light that is leaked out of the light guide by the leaking means.
