摘要： In an illumination device, an incidence angle of a laser beam, which is scanned by a laser beam scanning mechanism, with respect to a wavelength conversion member is set to an angle where the laser beam does not directly enter a projection lens when the wavelength conversion member is damaged, chipped or fallen off, and a laser light source and the laser beam scanning mechanism are located at a position corresponding to at least one of an upper side and a lower side of a light distribution pattern with respect to the wavelength conversion member, and are disposed to be deviated to either one of one side corresponding to a left side of the light distribution pattern and other side corresponding to a right side of the light distribution pattern.

摘要： A vehicle lamp includes a lamp unit which in turn includes a first lamp unit and a second lamp unit each provided with a light transmitting member and is configured to irradiate light emitted from a light emitting element toward a front of the vehicle lamp through the light transmitting member. In each of the first and second lamp units, the light transmitting member includes a direct light controller that directly emits light incident from the light emitting element onto the light transmitting member, toward the front of the vehicle lamp, and a total reflection controller that totally reflects the light and then emits the light toward the front of the vehicle lamp. A total reflection surface of the total reflection controller is divided into a plurality of reflection regions in a circumferential direction around the direct light controller.

摘要： A vehicle headlamp device to be applied to a vehicle includes a light source and a lens. The light source configured to emit illumination light. The illumination light is to pass through the lens. The lens includes an illumination light converging portion configured to, when a part of the illumination light passes through the illumination light converging portion, converge the part of the illumination light. The illumination light converging portion is provided in a region through which high-beam illumination light emitted from the light source passes. The illumination light converged by the illumination light converging portion is used as marking light at an optical axis adjustment that is performed during manufacturing of the vehicle.

摘要： Multiple light sources are arranged in an array. A light guide member receives light emitted from the multiple light sources on its back face, and outputs the light thus received from its front face. The light guide member has a base portion such that its back face faces the multiple light sources and such that it extends in the array direction of the multiple light sources. Multiple back-face protrusions and multiple front-face protrusions are formed such that they protrude from the back face and the front face of the base portion. The front-face protrusion has multiple continuous faces in the circumferential direction along the front face of the base portion.

摘要： Reliability of an in-vehicle headlight is improved by changing a light distribution pattern without using any mechanical configuration. The in-vehicle headlight includes a laser light source, a spatial light modulator, a spatial-light-modulator controller, and a projection lens. The laser light source emits a laser light beam. The spatial light modulator modulates a phase distribution of the laser light beam emitted by the laser light source. The spatial-light-modulator controller is provided in a headlight controller, and controls the spatial light modulator. The spatial-light-modulator controller controls the spatial light modulator so as to modulate the phase distribution of the laser light beam, and changes the light distribution pattern projected from the projection lens.

摘要： In a vehicle headlamp, a projection lens made of acrylic and a lens holder made of polycarbonate are joined with each other by a laser welding. The projection lens has a joint surface and is transparently formed. The lens holder has a welding surface that is joined to the joint surface and is transparently formed. The welding surface is irradiated with laser light having a wavelength of 1,550 nm to 1,640 nm transmitted through the projection lens to join the projection lens and the lens holder with each other.
