A light-emitting device includes a plurality of light source units each having a laser light source that outputs excitation light, and a phosphor unit that receives the excitation light and emits fluorescence. At least two light source units of the plurality of light source units are configured so that excitation light beams overlap each other on a light irradiation surface of the phosphor unit when the light irradiation surface is irradiated with the excitation light beams and so that longitudinal directions of long shapes of projection light beams on the light irradiation surface by the excitation light beams projected onto the light irradiation surface are parallel or substantially parallel to each other.

An illumination apparatus is provided that includes a yellow phosphor converter to receive a blue laser light beam and to convert a portion of the blue laser light beam to yellow light, a dichroic mirror optically coupled to the yellow phosphor converter to receive the phosphor-emitted light beam and to filter the phosphor-emitted light beam to provide a dichroic-filtered light beam, the dichroic mirror configured to pass yellow light and to reflect at least some blue light, and a blue light source optically coupled to the dichroic mirror to provide a blue light beam, the dichroic mirror configured to reflect the blue light beam in a same direction as the dichroic-filtered light beam.

A lighting apparatus includes a holder that holds an optical fiber, a wavelength converter that wavelength-converts laser light emitted from the optical fiber, and a case that is made of metal, holds the wavelength converter, and houses the holder. The holder includes a main body having a lead end face from which the laser light is emitted, and a flange projecting from an outer circumferential face of a base end of the main body. The case has a through hole penetrating from one end face to another end face, and the wavelength converter is attached to the case to be coaxial with the through hole. The through hole houses the main body, and has an abutting face which the lead end face of the main body abuts. The flange is secured to the case in a state where the lead end face of the main body abuts the abutting face.

An adaptive lighting system for an automotive vehicle. The adaptive lighting system has a wavelength conversion device for receiving the light radiation (L) from the primary source and re-emitting white light radiation (B). An optical imaging system receives the white light (B) re-emitted by the wavelength conversion device and projects this light (B) in front of the vehicle to form a lighting beam, the wavelength conversion device being situated close to a focal plane of the optical imaging system, and the scanning system and the optical system being situated on the same side of the wavelength conversion device. An intensity of the white light radiation (B) emitted by the wavelength conversion device is capable of being modulated between a minimum value and a maximum value, and the scanning is performed at variable speed.
