摘要： An automotive lamp includes: a light source; a light emitting member that receives light from the light source and emits light; and a support member that supports the light emitting member. The support member includes a translucent light emitting member accommodating unit. The light emitting member accommodating unit includes a recess in which the light emitting member is accommodated. A light incidence surface and side surfaces of the light emitting member are in contact with the light emitting member accommodating unit in a state in which the light emitting member is accommodated in the recess.

摘要： A vehicle lamp includes a semiconductor laser element configured to emit laser light, a condenser lens configured to condense the laser light, a phosphor configured to form white light by converting wavelength of at least a portion of the laser light condensed, and a reflector configured to reflect the white light. A light transmitting portion is formed in a portion, at which an extension path obtaining by extending an optical path of the laser light before contacting the phosphor is intersected with the reflector, of the reflector. A light confinement part is formed above the light transmitting portion.

摘要： A vehicle lamp includes a semiconductor laser element configured to emit laser light; a condenser lens configured to condense the laser light, a phosphor configured to form white light by converting wavelength of at least a portion of the laser light condensed, and a reflector configured to reflect the white light. A scattered light forming part is formed on a surface of the reflector, which is a surface at which a path obtained by extending an optical path of the laser light before the laser light hits the phosphor is intersected with the reflector.

摘要： In this invention, letters that can be seen by a pedestrian (101) are drawn on an intersection (103). A mark (MM2) that can be seen by the driver of the host vehicle (C) is drawn on the road (104) between the intersection (103) and the host-vehicle (C). The shapes of the letters (MO4) are corrected in accordance with the positional relationship between the pedestrian (101) and the intersection (103). The shape of the mark (MM2) is corrected in accordance with the positional relationship between the driver of the host-vehicle (C) and the road (104).

摘要： A head-up display device is provided in a vehicle together with a headlamp. The head-up display device includes a light source, a control unit, and a projection unit. The light source emits white light whose correlated color temperature is changeable. The control unit adjusts the correlated color temperature of the white light emitted from the light source. The projection unit forms image light by the white light emitted from the light source. The projection unit projects the image light onto a projection target member disposed in front of a driver of the vehicle, thereby displaying a virtual image superimposed on a landscape for the driver. The control unit adjusts the correlated color temperature of the white light emitted from the light source in accordance with a correlated color temperature of irradiation light emitted from the headlamp.

摘要： A lamp unit includes a reflecting device in which a micromirror array is selectively driven to selectively reflect incident light, the micromirror array being an array of micromirrors arranged in a matrix; a projection lens that projects the light selectively reflected by the reflecting device, forward in a light distribution pattern; and a restraining portion configured to restrain external light incident on the projection lens from being condensed in a region other than the micromirror array to restrain an increase in a temperature of the region.
