A vehicle headlamp includes a light source, a holding portion that holds the light source, and a reflector on which the holding portion is mounted and having a reflective surface for reflecting light from the light source. The reflector has a concave portion in a portion associated with the holding portion. The concave portion has a wall surface that reflects light from the light source on an end portion thereof on a vehicle inner side. The wall surface has a detour bending portion extending in an up-down direction and having a shape that winds back and forth on a front end periphery in a vehicle-mounted state.

A composite vehicle lamp includes: a lamp unit; and a lamp housing configured to house a plurality of the lamp units. Each of the plurality of the lamp units has: a light source; and an optical system configured to emit light from the light source in a desired light distribution. The plurality of the lamp units includes: one light-guide-type lamp unit having a light guide; and another light-guide-type lamp unit having another light guide whose form is different from that of the one light-guide-type lamp unit. The one light-guide-type lamp unit and the another light-guide-type lamp unit are turned on as lamps having the same function.

The invention describes an LED lighting assembly comprising a reflector unit comprising a number of reflector regions; an LED carrier realized to support at least one LED arrangement; and at least one positioning feature for positioning the LED carrier relative to the reflector unit, wherein a positioning feature is arranged in the same plane as the optical center of the LED arrangement. The invention further describes a method of manufacturing such an LED lighting assembly.

The present invention relates to a vehicle headlight that ensures improving usage efficiency of light focusing of light emitted from a light source. A vehicle headlight (1) has a main reflecting mirror (10) having an elliptic main reflecting surface (10a) and a light source (8) positioned at a first focal point (F1) of the main reflecting surface (10) and disposed opposed to the main reflecting surface (10). The vehicle headlight includes a reflection type polarizing plate (13) disposed between the main reflecting mirror (10) and a second focal point (F2) of the main reflecting mirror (10), an auxiliary reflecting mirror (11) that is disposed opposed to the reflection type polarizing plate (13) and reflects reflected polarized light (B12) by the reflection type polarizing plate (13) again to focus the reflected polarized light at the second focal point (F2) of the main reflecting surface (10), and a quarter-wave plate (14) that is disposed between the reflection type polarizing plate (13) and the auxiliary reflecting mirror (11) and disposed between the auxiliary reflecting mirror (11) and the second focal point (F2) of the main reflecting mirror (10).

A lighting device includes a first light emitting part including a first light source part and a first optical part that includes a first reflecting part and a second reflecting part. A first direction from the first reflecting part to the second reflecting part crosses a second direction from the first light source part to the second reflecting part. A direction from the first light source part to the first reflecting part is along a first plane which includes the first direction and the second direction, and crosses the second direction. A distance between the first reflecting part and the first light source part is larger than a distance between the second reflecting part and the first light source part. A light distribution angle of a first-reflecting-part light in the first plane is larger than the light distribution angle of the second-reflecting-part light in the first plane.
