摘要:
Disclosed is a vehicle lamp. Three lamp units are arranged such that an optical axis of each lamp unit is oriented in a longitudinal direction of a vehicle body. A base of a front lamp unit is fixed to the vehicle body, and bases of a middle lamp unit and a rear lamp unit are provided to be movable in a widthwise direction of the vehicle body. A housing of each of the middle and rear lamp units is suspended on an output shaft of an actuator by an arm. The actuator pivots the output shaft around a horizontal axis and swings the arm around an axis in which is parallel with the optical axes of the middle and rear lamp units.

Disclosed is a vehicular lamp having a light source and a light guide body. In the vehicular lamp, the light guide body is configured by a first and a second rod shaped light guiding portions disposed at positions spaced apart from each other, and a planar light guiding portion disposed to connect the circumferential surface portions of the first and second rod shaped light guiding portions with each other. Further, the light source configured to include a first light source and a second light source disposed to cause light to be incident from an end portion surfaces of the first and the second rod shaped light guiding portions, respectively, and then configured to make each of the first light source and the second light source to emit a different color light with each other.
摘要:
An automotive combined turn signal and tail/stop lamp (10) having co-axial transparent collimating inner and outer light guides (18, 30). Inner collimating light guide (18) receives light from a yellow LED (16), outer collimating light guide (30) receives light from red LEDs (14), the yellow and red LEDs located in thermal communication with a common heat sink (2). Mirror optics (40, 42) reflect light from respective light output prisms (28, 35) of the inner and outer light guides outward to nested reflectors on the automobile. Electrical conductors (48) between the light guides (18, 30) can feed power from a PC board (12) to supply additional light sources within an RCL housing, such as white back-up light.

Disclosed is a hybrid lamp assembly (10) which includes a substantially parabolic reflector (12) having an open end (20) and a circumferential mounting member (18) extending outwardly from the open end (20) of the reflector (12). The mounting member (18) presents a plurality of nonparallel mounting surfaces (22). A primary, non-LED light source (14) is operably assembled with the parabolic reflector (12). A secondary light source (24), comprising a plurality of LED lamps (26), is positioned circumferentially around the open end (20) on the mounting surfaces (22). The LED lamps (26) are each mounted to project in a direction (42) substantially normal to the surface on which it is mounted.

A lighting system (10) comprising a primary light engine (20); a secondary light engine (22); and a projection apparatus (14, 14a-b) comprising a reflector (28) configured to reflect electromagnetic radiation emitted from the primary light engine (20); a projector lens (28) configured to project at least a portion of the reflected electromagnetic radiation from the reflector (28); and a shutter (24, 24a-c) disposed between the secondary light engine (22) and the reflector (28). The shutter (24, 24a-c) is configured to selectively obscure a portion of the projector lens (28) from the reflected electromagnetic radiation and is further configured to selectively emit at least a portion of electromagnetic radiation from the secondary light engine (22) through at least a portion of the projector lens (28).

Disclosed are a head lamp for a vehicle and a method of controlling the same. The head lamp for a vehicle according to an exemplary embodiment of the present invention includes: a first lamp module; and a second lamp module disposed at a front side of the first lamp module, in which a mode of the second lamp module is set to one of a first mode in which a portion of the second lamp module is overlapped with the first lamp module on a light proceeding path, and a second mode in which the second lamp module is not overlapped with the first lamp module.

A vehicle lighting unit can include a daytime running lamp (DRL) function and a light emission unit that can be miniaturized. The vehicle lighting unit can include a headlamp (HL) unit having a HL light guiding lens and a DRL unit. The HL light guiding lens can include a light incident surface in front of a light source LED for HL, a front reflection surface, a rear reflection surface, and a light-transmitting section. The front reflection surface can internally reflect light from the light incident surface obliquely rearward and downward. The rear reflection surface can internally reflect the light from the front reflection surface. The light-transmitting section is disposed between the front and rear reflection surfaces in terms of its vertical direction. The DRL unit can be disposed behind the light-transmitting section, so that light from the DRL unit can pass through the light-transmitting section and projected forward.

摘要:
Various techniques are described herein for combining two or more LEDs in a single reflective cavity for a rear lamp in an automobile. The LEDs may be two or more different colors for performing different functions, such as a stop light, a turn signal, and a tail light. In one embodiment, the LEDs have side emitting lenses and are coaxially aligned in a parabolic reflector. The LEDs may be mounted facing each other or mounted in the same direction, or a combination of both. The LEDs may share a common heat sink. A second reflector may be positioned inside a larger reflector, where a first LED is mounted near the focal point of the larger reflector, and a second LED is mounted near the focal point of the inner reflector. Additional LEDs may also be mounted in either reflector and separately controlled.
