Abstract

A light fixture is provided for use in photographic chambers that provides a combination of high flux, the ability to place/tuck the light fixture against a wall, and the ability to flash/tune the light fixture dynamically. The light fixture is based on light emitting diode elements to provide an energy efficient light source that generates far less heat than traditional mercury arc based lamps. The light fixture is modular and can be daisy chained to supply power and/or control signals to multiple attached light fixtures. Individual light fixtures may be joined together to form an array of light fixtures. The light fixtures may utilize the digital multiplex DMX512 standard for digital communication networks for controlling the light elements within the fixtures. The light fixture has a light output that is capable of providing a wide beam angle.

First claim

The invention claimed is:

1. A light fixture comprising:
a housing;
a rotatable heatsink coupled to the housing;
wherein the rotatable heatsink comprises an overhang extending beyond an edge of the housing, and
wherein the overhang creates an offset allowing a cable to pass between the light fixture and another light fixture arranged in an array; and
one or more lighting lenses coupled to the rotatable heatsink,
wherein a property of light emitted through at least one of the one or more lighting lenses is changed, in response to the rotatable heatsink being rotated relative to the housing.

2. The light fixture of claim 1 , further comprising an airline with a set of nozzles that supply air in periodic bursts to clean components of the light fixture.

3. The light fixture of claim 1 , further comprising an airline with a set of nozzles that supply a continuous supply of air to cool components of the light fixture.

4. The light fixture of claim 1 , further comprising a signal bus configured to join a plurality of light fixtures in the array.

5. The light fixture of claim 1 , wherein the property of the light comprises a light spread of the one or more lighting lenses.

6. The light fixture of claim 1 , wherein the rotatable heatsink is coupled to a top portion of the housing.

7. The light fixture of claim 1 , wherein, in response to the rotatable heatsink being rotated, a sundog light formation is emitted by the light fixture.

8. A method of using a light fixture, the method comprising
coupling a rotatable heatsink to a housing;
rotating the rotatable heatsink relative to the housing to change a property of light emitted through at least one of the one or more lighting lenses;
arranging the light fixture and another light fixture in an array;
passing a cable between the light fixture and the another light fixture and through an offset created by an overhang of the rotatable heatsink, wherein the overhang extends beyond an edge of the housing; and
activating one or more lights emitted through one or more lighting lenses coupled to the rotatable heatsink.

9. The method of claim 8 , further comprising activating an airline with a set of nozzles that supply air in periodic bursts to clean components of the light fixture.

10. The method of claim 8 , further comprising activating an airline with a set of nozzles that supply a continuous supply of air to cool components of the light fixture.

11. The method of claim 8 , further comprising joining a plurality of light fixtures in the array using a signal bus.

12. The method of claim 8 , wherein the property of the light comprises a light spread of the one or more lighting lenses.

13. The method of claim 8 , wherein the coupling the rotatable heatsink comprises coupling the rotatable heatsink to a top portion of the housing.

14. The method of claim 8 , further comprising rotating the rotatable heatsink to create a sundog light formation.

15. A method of manufacturing a light fixture, the method comprising:
coupling one or more lighting lenses to a rotatable heatsink;
coupling the rotatable heatsink to a housing,
wherein a property of light emitted through at least one of the one or more lighting lenses is changed, in response to the rotatable heatsink being rotated relative to the housing;

arranging the light fixture and another light fixture in an array; and
passing a cable between the light fixture and the another light fixture through an offset created by an overhang of the rotatable heatsink,
wherein the overhang extends beyond an edge of the housing.

16. The method of claim 15 , further comprising placing an airline with a set of nozzles that supply air in periodic bursts to clean components of the light fixture.

17. The method of claim 15 , further comprising placing an airline with a set of nozzles that supply a continuous supply of air to cool components of the light fixture.

18. The method of claim 15 , further comprising joining a plurality of light fixtures in the array using a signal bus.

19. The method of claim 15 , wherein the property of the light comprises a light spread of the one or more lighting lenses.

20. The method of claim 15 , wherein, in response to the rotatable heatsink being rotated, a sundog light formation is emitted by the light fixture.
