Abstract

A vehicle headlamp system includes a headlamp component with a reflecting element and a light source. The reflecting element includes an array of selectively controllable portions, and the light source provides a first output to the reflecting element. The system further includes a computer coupled to the light source and the reflecting element. The computer selectively operating the portions of the reflecting element to shape the first output into illumination areas according to at least one vehicle user characteristic.

Claims

1. A system, comprising:

a vehicle headlamp including a reflecting element and a light source, the reflecting element including an array of selectively controllable portions, the light source providing a first output to the reflecting element; and

a computer coupled to the light source and the reflecting element, the computer selectively operating the portions of the reflecting element to shape the first output into illumination areas according to at least one vehicle user characteristic.

2. The system of claim 1, wherein the light source of the vehicle headlamp includes an LED component.

3. The system of claim 2, wherein the light source of the vehicle headlamp is an assembly of four LED components.

4. The system of claim 3, wherein the light source of the vehicle headlamp includes a collimator component directing the first output to the reflecting element.

5. The system of claim 3, wherein the assembly of four LED components is in the configuration of a two by two array.

6. The system of claim 4, wherein the four LED components are each a 1 mm by 1 mm chip LED.

7. The system of claim 6, wherein the light source provides the vehicle headlamp with an output of at least 70,000 candela.

8. The system of claim 1, wherein the vehicle headlamp includes a lens and a housing containing the light source, the reflecting element, and the lens.

9. The system of claim 1, wherein the vehicle headlamp includes a lens and a housing, the housing supporting the light source, the reflecting element, and the lens therewith.

10. The system of claim 9, wherein the housing has a shape of a rectangular box.

11. The system of claim 10, wherein the housing has dimensions substantially equal to 70 mm by 70 mm by 100 mm.

12. The system of claim 10, wherein the reflecting element is a digital micromirror device and the light source is an assembly of four 1 mm by 1 mm chip LEDs configured in a two by two array.

13. The system of claim 12, wherein the reflecting element has dimensions substantially equal to 20.75 mm by 11.67 mm.

14. The system of claim 1, further comprising a power system coupled to the light source, the reflecting element, and the computer.

15. The system of claim 14, wherein the reflecting element is a digital micromirror device, the light source is an assembly of four 1 mm by 1 mm chip LEDs configured in a two by two array, and the light source draws substantially 18-watts of power from the power system to provide the vehicle headlamp an output of at least 70,000 candela.

16. The system of claim 1, wherein the at least one vehicle user characteristic is one of a height and a vision quality of a vehicle user.
