Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A light-emitting device includes a semiconductor laser element arranged in a first space, a resin member arranged in a second space, a light transmitting member that transmits light emitted from the semiconductor laser element, the light transmitting member being included in a wall separating the first space from the second space; and a wavelength-converting member that absorbs the light emitted from the semiconductor laser element and passing through the light transmitting member and converts wavelength of the light. The first space and the second space are isolated from each other so as not to exchange any gas therebetween.
