摘要： A vehicle headlight (1), which is one aspect of a vehicle illumination lamp, includes: light sources (52R, 52G, 52B), and diffraction gratings (54R, 54G, 54B) for diffracting light incident from the light sources (52R, 52G, 52B). The light diffracted by the diffraction gratings (54R, 54G, 54B) is irradiated in a predetermined light distribution pattern. A projection area (AR) to which are projected components (LCR, LCG, LCB) advancing and passing through the diffraction gratings (54R, 54G, 54B) among the light incident on the diffraction gratings (54R, 54G, 54B) is positioned below the light distribution pattern and within a range (RNG) in which a field of view of a driver of a vehicle is obstructed by the vehicle.

摘要： The invention relates to a headlight for a motor vehicle having a plurality of main light modules configured to produce a main light distribution for low beam and high beam. The headlight also has a laser light module comprised of one or more laser diodes configured to produce a laser light distribution in addition to the main light distribution. The headlight is configured such that, during operation, the laser light distribution is movable in a manner decoupled from the main light distribution and relative to the main light distribution.

摘要： An irradiation unit is disclosed that includes a pump radiation source for emitting pump radiation in the form of a beam, a conversion element for at least partially converting the pump radiation into conversion radiation, and a support on which the conversion element is situated. The support accommodates a through-hole through which the beam including the pump radiation is incident on an incident surface of the conversion element, the though-hole being laterally delimited by an inner wall face of the support, at least one portion of the face tapering in the direction of the incident surface. During operation, the pump radiation conducted in the beam is at least intermittently at least in part, incident on the inner wall face of the support and is reflected thereby onto the incident surface.

摘要： A headlight module includes a light source, a light distribution control element and a projection optical element. The light source emits light. The light distribution control element forms a light distribution pattern by changing a divergence angle of the light incident therein. The projection optical element projects the light distribution pattern. The light distribution control element includes a first light distribution formation part configured to form a high luminosity region in the light distribution pattern and a second light distribution formation part configured to form a low luminosity region in the light distribution pattern. The low luminosity region is lower in luminosity than the high luminosity region.

摘要： A light emitting device includes a wavelength conversion element, and an excitation light source which radiates excitation light to the wavelength conversion element. The wavelength conversion element includes a support member having a supporting surface, and a wavelength conversion member disposed on the supporting surface so as to be contained within the support member when the support member is viewed from the supporting surface side. An outer peripheral region on the support member, which is an outer peripheral portion of an arrangement region including the wavelength conversion member and is exposed from the wavelength conversion member, includes a light absorbing portion which can absorb first light having same wavelength as the excitation light or a light scattering portion which can scatter the first light. The arrangement region includes a reflective member which is disposed between the wavelength conversion member and the support member, and is different from the support member.
