Abstract

A vehicle lighting assembly is provided that comprises a single heat sink defining a plurality of cavities. The heat sink is within, and movable relative to, a housing. The vehicle lighting assembly further comprises a plurality of optic polyhedrons configured within the cavities and a plurality of LED light sources within the cavities is configured to direct an incident light pattern through the optic polyhedrons to generate a plurality of vehicular light patterns.

Claims (21)

1. A vehicle lighting assembly, comprising:

a single heat sink defining a plurality of cavities, wherein the heat sink is within a housing;

a plurality of optic polyhedrons configured within the cavities; and

a plurality of LED light sources within the cavities configured to direct an incident light pattern through the optic polyhedrons to generate a plurality of vehicular light patterns,

wherein the heat sink is pivotable along three independent datums relative to the housing to calibrate one or more of the vehicular light patterns.

2. The vehicle lighting assembly of claim 1 , wherein the heat sink is configured to dissipate thermal energy from the LED light sources in both vehicle forward and rearward directions.

3. The vehicle lighting assembly of claim 1 , wherein the heat sink comprises a visible outer edge that extends past the cavities vehicle forward.

4. The vehicle lighting assembly of claim 1 , wherein the vehicular light patterns are a low-beam pattern, a high-beam pattern, and a daytime running light pattern.

5. The vehicle lighting assembly of claim 4 , wherein the optic polyhedrons that generate the low-beam pattern and the high-beam pattern also collectively generate the daytime running light pattern.

6. The vehicle lighting assembly of claim 1 , wherein each optic polyhedron comprises a front side comprising a plurality of micro-optic elements, and further wherein each micro-optic element comprises a front face having a surface area from about 0.25 millimeters squared to about 25 millimeters squared.

7. The vehicle lighting assembly of claim 1 , wherein each optic polyhedron comprises a plurality of near-field lens (NFL) elements configured to collimate the incident light pattern into the vehicular light patterns.

8. The vehicle lighting assembly of claim 1 , wherein the heat sink defines an open end, and further wherein a lens is disposed over the open end.

9. The vehicle lighting assembly of claim 6 , wherein the optic polyhedrons and the plurality of micro-optic elements are formed of silicone.

10. A vehicle lighting assembly, comprising:

a single heat sink defining a plurality of cavities within a housing; and

a plurality of optic polyhedrons and corresponding LED light sources within the cavities,

wherein the LED light sources direct incident light patterns through the polyhedrons to generate a plurality of vehicular light patterns, and the heat sink is pivotable along a plurality of independent datums relative to the housing to calibrate one or more of the vehicular light patterns.

11. The vehicle lighting assembly of claim 10 , wherein the heat sink comprises a visible outer edge that extends past the cavities vehicle forward.

12. The vehicle lighting assembly of claim 10 , wherein the vehicular light patterns comprise a low-beam pattern, a high-beam pattern, and a daytime running light pattern, and further wherein the optic polyhedrons that generate the low-beam pattern and the high-beam pattern also collectively generate the daytime running light pattern.

13. The vehicle lighting assembly of claim 12 , wherein the low-beam pattern and the high-beam pattern meet respective the low-beam pattern requirements and high-beam pattern requirements set forth in the current U.S. National Highway Traffic Safety Administration Federal Motor Vehicle Safety Standard 108.

14. The vehicle lighting assembly of claim 10 , wherein each optic polyhedron comprises a front side comprising a plurality of micro-optic elements, and further wherein each micro-optic element comprises a front face having a surface area from about 0.25 millimeters squared to about 25 millimeters squared.
