Abstract

A light providing improved visibility during adverse conditions includes an array of discrete lights distributed over a surface. The discrete lights are configured to distribute directional light over a three-dimensional space. A regulation and multiplexing circuit is coupled to the array of discrete lights and configured to power discrete lights such that the regulation and multiplexing circuit strobes the discrete lights in accordance with environmental conditions to reduce or eliminate perceived streaking of precipitation or debris to improve operator visibility.

Claims

1. A light providing improved visibility during adverse conditions, comprising:

an array of discrete lights distributed over a surface, the discrete lights being configured to distribute directional light over a three-dimensional space; and

a regulation and multiplexing circuit coupled to the array of discrete lights and configured to power discrete lights such that the regulation and multiplexing circuit strobes the discrete lights in accordance with environmental conditions including a rate of precipitation or debris falling to reduce or eliminate perceived streaking of reflected light due to precipitation or debris to improve operator visibility.

2. The light as recited in claim 1, wherein the discrete lights include light emitting diodes arranged at different angles across the array.

3. The light as recited in claim 1, wherein the regulation and multiplexing circuit strobes a pattern wherein less than all of the discrete lights are lit during a single instant.

4. The light as recited in claim 1, further comprising a sensor configured to enable the regulation and multiplexing circuit during an environmental condition.

5. The light as recited in claim 4, wherein the regulation and multiplexing circuit is adjusted in accordance with the environmental condition.

6. The light as recited in claim 1, further comprising a user interface configured to adjust the regulation and multiplexing circuit.

7. The light as recited in claim 1, wherein the regulation and multiplexing circuit controls at least one of hue, duty cycle, pulse rate, and enablement of the discrete lights.

8. The light as recited in claim 1, wherein the surface is configured to provide distributed angles for the discrete lights.

9. The light as recited in claim 1, wherein the light includes one of a headlight and a flash light.

10. A strobing light system providing improved visibility during adverse conditions, comprising:

at least one light including an array of discrete lights distributed over a surface, the discrete lights being configured to distribute directional light over a three-dimensional space;

a controller responsive to an input to enable a lighting mode; and

a regulation and multiplexing circuit coupled to the array of discrete lights and configured to power discrete lights in accordance with the lighting mode such that the regulation and multiplexing circuit strobes the discrete lights in accordance with environmental conditions including a rate of precipitation or debris falling to reduce or eliminate perceived streaking of reflected light due to precipitation or debris to improve operator visibility.

11. The light as recited in claim 10, wherein the discrete lights include light emitting diodes arranged at different angles across the array.

12. The light as recited in claim 10, wherein the regulation and multiplexing circuit strobes a pattern wherein less than all of the discrete lights are lit during a single instant.

13. The light as recited in claim 10, further comprising a sensor configured to enable the regulation and multiplexing circuit during an environmental condition.

14. The light as recited in claim 13, wherein the regulation and multiplexing circuit is adjusted in accordance with the environmental condition.

15. The light as recited in claim 10, further comprising a user interface configured to adjust the regulation and multiplexing circuit.

16. The light as recited in claim 10, wherein the regulation and multiplexing circuit controls at least one of hue, duty cycle, pulse rate, and enablement of the discrete lights.

17. The light as recited in claim 10, wherein the surface is configured to provide distributed angles for the discrete lights.

18. A method for improving visibility during adverse conditions, comprising:

providing at least one light including an array of discrete lights distributed over a surface, the discrete lights being configured to distribute directional light over a three-dimensional space;

enabling a lighting mode in accordance with environmental conditions; and

regulating energy to discrete lights in the array of discrete lights in accordance with the lighting mode and characteristic of the environmental conditions including a rate of precipitation or debris falling such that the discrete lights are strobed in a plurality of directions to reduce or eliminate perceived streaking of reflected light due to precipitation or debris to improve operator visibility.

19. The method as recited in claim 18, wherein the discrete lights include light emitting diodes arranged at different angles across the array and wherein regulating includes strobing a pattern of discrete lights wherein less than all of the discrete lights are lit during a single instant.

20. The method as recited in claim 18, wherein enabling a lighting mode includes sensing an environmental condition to enable the lighting mode.

21. The method as recited in claim 18, wherein regulating includes adjusting one or more of hue, duty cycle, pulse rate, and enablement of the discrete lights in accordance with one of the environmental condition and user preference.
