A lamp unit includes: a light emitting element; a reflector that reflects light emitted from the light emitting element toward a unit front; and a heat sink that supports the light emitting element and the reflector, in which a power supply attachment for supplying power to the light emitting element is attached to the heat sink, the power supply attachment is fastened to the heat sink at two left and right positions of the power supply attachment, and a connector portion of the power supply attachment is formed inside two left and right fastening positions so as to extend to a unit rear side relative to a rear end position of the reflector.

Lamp unit and power supply attachment

A first camera unit () acquires an image including at least an area ahead of a vehicle based on a first optical axis (X). A second camera unit () acquires an image including at least an area on the left of the vehicle based on a second optical axis (X). When viewed from an up-down direction of the vehicle, the first optical axis (X) and the second optical axis (X) intersect with each other.

Sensor system, sensor module, and lamp device

A vehicle headlamp includes a lamp outer case, a holding plate, a lamp unit, and an optical axis adjustment mechanism. The lamp outer caseincludes a lamp housingformed with an opening on at least one side thereof and a covercovers the opening of the lamp housing. The holding plateis pivotable in at least one of an up-down direction and a right-left direction. The lamp unitis attached to the holding plateand includes a light source. The optical axis adjustment mechanismis disposed below the lamp unitand adjusts an optical axis direction of the lamp unit

Vehicle headlamp

A vehicle headlamp includes a light source configured to emit light, a reflector configured to reflect the light, a projection lens through which the light is projected, and a lens holder holding the projection lens. The projection lens has a positioning portion, and the lens holder is formed with a jig insertion hole at a location corresponding to the positioning portion in a direction around an optical axis of the projection lens such that the positioning portion is visible through the jig insertion hole. When mounting the projection lens to the lens holder, a positioning jig is inserted through the jig insertion hole and is engaged with the positioning portion to position the projection lens in the direction around the optical axis of the projection lens.

Vehicle headlamp and projection lens mounting method

A vehicle headlamp is provided with: a projection lens disposed on an optical axis extending in a front and rear direction of a vehicle; a light source disposed rearwardly of a rear-side focal point of the projection lens; a reflector configured to reflect direct light from the light source forward to converge reflected light toward the optical axis; a movable shade disposed between the projection lens and the light source and configured to blocking a part of the reflected light from the reflector and a part of the direct light from the light source to form a cutoff line in a light distribution pattern; and a bracket formed from a metal plate member and disposed between the projection lens and the light source, wherein the movable shade is rotatably supported on the bracket. An opening portion is formed in the bracket and configured to pass a part of the reflected light from the reflector along the optical axis. A shade portion is provided on the opening portion and configured to cover a gap between the movable shade and an opening edge of the opening portion.

A lighting unit to be used for illumination includes an LED unit having a semiconductor light emitting unit, a radiating board for directly fixing the semiconductor light emitting unit to an upper surface, and a contact formed on the radiating board and serving to input a power to cause the semiconductor light emitting unit to emit a light, an attachment having a power supply portion for surrounding and holding the LED unit and supplying a power to cause the semiconductor light emitting unit to emit a light from an external power plug to the contact in a state in which at least a part of lower and side surfaces of the radiating board and an upper part of the semiconductor light emitting unit are open.
