A vehicle lamp is configured in such a manner as to project light from light-emitting elements (22 and 42) of a first and a second lamp unit (20 and 40) forward through lenses (30 and 50) in the lamp and accordingly form a low-beam light distribution pattern having a Z-shaped cut-off line. In addition, a part of a plurality of lens elements formed on a front surface (30a, 50a) of each of the lenses (30 and 50) is formed as a specific lens element (30aA3, 50sB3) having a freeform surface shape. It is configured in such a manner as to form an inclined portion of the Z-shaped cut-off line with light emitted from the specific lens elements (30sA3 and 50sB3). Consequently, the degree of flexibility in forming the Z-shaped cut-off line is increased.

A vehicular headlamp includes a light source on which a light emitting diode is mounted on a substrate, a heat spreading plate attached to the substrate so as to be capable of transferring heat, a holding member integrated with the heat spreading plate, a heat pipe comprising a first end portion and a second end portion, each of which having a circular cross-section, the first end portion being rotatably engaged with the holding member, and a heat sink connected to the second end portion.

A light source module includes first LED elements that emit blue light, second LED elements that emit amber light, and a wavelength conversion member disposed in optical paths of the first LED elements and the second LED elements. The wavelength conversion member converts a portion of the blue light emitted by the first LED elements to yellow light, transmits a portion of the blue light emitted by the first LED elements, and substantially transmits the amber light emitted by the second LED elements.

The invention provides a lighting system for generating patterned phosphor-converted output beams for projection onto a pixelated display unit (24). A phosphor screen arrangement (18) comprises a plurality of separate light-receiving surface regions (34), each region (34) illuminated by an individually addressable laser source arrangement. By controlling the relative intensity of light directed to each of the surface regions (34), a broad range of different output beam patterns can be created from the phosphor screen arrangement (18). The generated beam pattern may be controlled so as to correspond with the pixel configuration of the display unit (24), such that light is directed only toward pixels (26) which are active, rather than inactive. This enables significant improvements in optical efficiency, since light need not be wasted through propagation toward pixels (26) which are configured simply to discard it.

A vehicular lamp includes a light emitter, a first light guide, and a second light guide. The first light guide has a first incident surface, a first light guiding portion that guides the entering light, a first light emission surface that emits light guided by the first light guiding portion, and a first reflecting surface that reflects the light guided by the first light guiding portion in a direction toward the second light guide. The second light guide has a second light emission surface that emits light that enters the second light guide after being reflected by the first reflecting surface, and a second reflecting surface that reflects the light that enters the second light guide after being reflected by the first reflecting surface toward the second light emission surface.

A vehicular lighting apparatus that is relatively small, low cost, superior in mountability, and offers a superior design. The vehicular lighting apparatus may include a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits illumination light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle.

A vehicle lamp is configured to be able to selectively perform low-beam irradiation and high-beam irradiation. The vehicle lamp includes first and second light-emitting elements and a reflector for reflecting light emitted from these first and second light-emitting elements toward a front. A reflecting surface of the reflector has a first reflection region on which light emitted from the first light-emitting element is incident and a second reflection region on which light emitted from the first light-emitting element is not incident but light emitted from the second light-emitting element is incident. A low-beam light distribution pattern having horizontal and oblique cutoff lines is formed by turning on the first light-emitting element. A high-beam light distribution pattern is formed by turning on the second light-emitting element or simultaneously turning on the first and second light-emitting elements.

A vehicle lamp includes a plurality of types of light output units having different illumination functions, a light emission drive unit configured to cause the plurality of types of light output units to output lights, and a monitoring sensor. The vehicle lamp is arranged at an upper part of a vehicle.
