Abstract: A light source unit provided with a light-emitting element as a light source is attached to a rear wall section of a housing. The light source unit is attached to the housing, in the state where a socket is inserted in an opening formed in the rear wall section and an elastic seal member attached to the front end of the socket is pressed against the rear wall section. A rib extending toward a lamp rear side so as to surround at least the upper half section of the opening is formed on the rear wall section of the housing.

Abstract: In a vehicle lamp, an optical axis adjustment screw for pivoting an optical member around a pivotal axis extending in a vehicle width direction is supported by a lamp body in a state of extending in a vertical direction on the rear side of the vehicle lamp with respect to pivotal axis. A protruding piece extending toward the rear of the vehicle lamp is formed in the optical member, and a groove portion to be screwed with a threaded portion of the optical axis adjustment screw is formed in the rear end surface of the protruding piece. The groove portion of the protruding piece and the threaded portion of the optical axis adjustment screw can be maintained in the screwed state.

Abstract: The vehicle lamp of the present disclosure includes a substrate, a heat dissipating member, a reflector, and a fastening member. The reflector includes a boss portion that protrudes toward the heat dissipating member side and includes a fastening hole. The substrate includes a first opening. The heat dissipating member is in contact with the substrate to be thermally conductive with the substrate and includes a first portion that includes a second opening, a second portion that is more spaced apart from the reflector than the first portion to include an insertion hole and a fastening seat surface, and a connecting portion that connects the first portion and the second portion to each other. The boss portion passes through the first opening and the second opening and abuts to the second portion such that the fastening hole and the insertion hole overlap with each other.

Abstract: A vehicular light fixture having a lamp body opened to a front surface thereof, a lens covering the front opening of the lamp body, and a light source bulb disposed in a light chamber defined by the lamp body and the lens, the lamp body being made of a synthetic resin and formed at a part thereof with bent zones, other portions of the lamp body than the bent zones having a substantially uniform wall thickness, and the bent zones having a smaller wall thickness than the other portions of the lamp body than the bent zones.

Abstract: An automobile headlamp includes: a lamp body having a front opening; a headlamp body having a light source and a reflector provided inside the lamp body; an extension reflector provided around the headlamp body for hiding the inside of the lamp body, the extension reflector having a mirror surface; and a front lens engaging with the front opening of the lamp body. The front lens has side walls, steps formed on the side walls of the front lens so as to decrease the distance between the front edges of the side walls, and a plurality of thick portions formed behind the steps on the inner surfaces of the side walls of the front lens, the thick portions to which the extension reflector is connected with screws.

Abstract: A vehicle headlamp having a paraboloidal reflector and an electric lighting bulb mounted in a lighting chamber. The paraboloidal reflector is formed to include a pair of vertically opposed flat portions extending therefrom toward a cover lens. The bulb has a vitreous envelope containing a primary filament for providing an upper beam, and an auxiliary filament for providing a lower beam. A shade is disposed between the bulb and the upper flat portion of the reflector in order to prevent the bulb from directly irradiating the upper flat portion of the reflector. Characteristically, the shade is inclined with respect to the optical axis of the headlamp, instead of being disposed parallel thereto, so as to extend in a direction in which the rays of light emitted by the axuillary filament of the bulb travels after having been reflected by part of the paraboliodal reflector, in order to make utmost use of the light rays emitted by the auxilliary filament for providing the lower beam.
