A luminescent emblem includes a housing including a reflection surface, a cover including at least one transmissive part through which visible light transmits, and a substrate on which a light source is mounted. The housing includes a bottom wall portion, an outer peripheral wall portion, and a connection wall portion. The bottom wall portion includes a projection projecting toward the cover. The projection includes a flat portion and an inner peripheral wall portion surrounding the flat portion. The at least one transmissive part includes a transmissive part disposed on a peripheral portion of the cover. The reflection surface includes a primary reflection surface that reflects visible light toward a peripheral side of the housing and a secondary reflection surface that receives and reflects light toward the transmissive part, disposed on the peripheral portion of the cover.

Luminescent emblem

A light emitting device includes: a first semiconductor laser element; a second semiconductor laser element; and a light exit surface which emits light from the first semiconductor laser element and the second semiconductor laser element. The first semiconductor laser element is disposed at a position farther than the second semiconductor laser element as seen from a flat surface including a point on a surface of the light exit surface and perpendicular to a light extraction direction.

Light emitting device

Provided is a light-emitting device having low angle dependence of chromaticity as well as achieving wide-angle light distribution. The light-emitting device has a semiconductor laser diode, a first lens, a second lens, and a wavelength converting part for converting the wavelength of the laser beam emitted from the semiconductor laser diode. The first lens has a first spread angle and refracts the laser beam emitted from the semiconductor laser diode. The second lens has a second spread angle and refracts the laser beam refracted by the first lens. The second spread angle is larger than the first spread angle.

Light-emitting device

A light-emitting device includes a plurality of semiconductor laser elements including a first semiconductor laser element, and a plurality of reflectors including a first reflector for reflecting light emitted from the first semiconductor laser element, each of reflectors reflecting light emitted from corresponding one of the plurality of semiconductor laser elements. Light emitted from the first semiconductor laser element passes through a gap between two of the plurality of reflectors excluding the first reflector and reaches the first reflector. Lights emitted from the plurality of semiconductor laser elements are extracted in a direction different than an incident direction thereof toward the plurality of reflectors.

A light-emitting device includes a laser diode element, a wavelength-converting member that absorbs light emitted from the laser diode element and converts wavelength of the light, and a transparent conductive film that is arranged on at least one of a light extracting-side surface and a laser diode element-side surface of the wavelength-converting member. The transparent conductive film is configured such that electrical resistance in a region overlapping the wavelength-converting member increases when the wavelength-converting member is damaged.
