Abstract
Disclosed is a vehicle lighting module. The module uses material that is configured into conical reflectors which are defined into the body. The reflectors include light guides which, along with the reflectors direct illumination from aligned LEDs into a condenser lens.
Claims20
A vehicle headlamp, comprising:
- a plurality of light-emitting diodes (LEDs) mounted on a substrate;
- a plurality of light guides each formed of a transparent material into a conical shape, such that the conical shape has a narrow end opposite a wide end, the narrow end providing a light entry, each light entry being oriented to receive light emitted from a particular LED in the plurality;
- a body comprised of a reflective white material, the body substantially including the plurality of light guides to form a common substantially-solid mass;
- a plurality of discretely defined reflector arrangements formed within the body for reflecting light within each of the plurality of light guides, respectively;
- and
- an outer lens adapted to receive light from the plurality of light guides and project the light out of the headlamp.
3 more elements
An illumination device comprising:
- a first light-emitting diode (LED) oriented to emit light in a first direction;
- a second LED oriented to emit light in a second direction;
- a first reflector having a conical shape and a second reflector having a conical shape, the first and second reflectors each being defined into a body of reflective material;
- the first reflector oriented to modify light received from the first LED, and the second reflector oriented to modify light received from the second LED;
- a first light guide and a second light guide included in the first reflector and the second reflector, respectively, wherein the first and second light guides are formed into a conical shape from a transparent material;
- and
- the first light guide is configured to receive and direct light from the first LED and the second light guide configured to receive and direct light from the second LED, wherein the first and second light guides are formed within the body of reflective material to form a common substantially-solid mass.
4 more elements
A vehicle headlamp, comprising:
- a plurality of light-emitting diodes (LEDs) mounted on a substrate;
- a plurality of light guides each formed of transparent material, wherein each of the plurality of light guides has a conical-shaped portion and a cylindrical-shaped portion, wherein the conical-shaped portion has a narrow end opposite a wide end, the narrow end providing a light entry oriented to receive light emitted from a particular one of the plurality of LEDs, and the wide end providing a light exit oriented to emit light into the cylindrical-shaped portion;
- a body comprised of a reflective white material, the body having a plurality of openings configured to accept the plurality of light guides such that the body substantially prevents lateral bleeding of light between each of the plurality of light guides;
- a plurality of outer lenses adapted to receive light from the plurality of light guides, respectively, and project the light out of the headlamp;
- and
- a control system electronically connected with the plurality of LEDs, the control system configured to individually control illumination of each of the plurality of LEDs for shaping a pattern of light emitted from the vehicle headlamp.
