Abstract

The disclosed technology relates to a lighting system that utilizes an ambient light sensor to detect at least one of a color temperature and intensity of ambient light to set or adjust at least one of an intensity and color temperature of light to be emitted by a plurality of LEDs. The plurality of LEDs include RGB+WW LEDs.

Claims (50)

1. A lighting system for use with a portable electronic device, comprising:

a lighting assembly comprising a plurality of LEDs comprising RGB+WW LEDs, wherein the plurality of LEDs is configured to emit light in a first direction;

an ambient light sensor configured to detect at least one of a color temperature and an intensity of ambient light;

a processor configured to:

receive an output from the ambient light sensor, the output representative of the at least one of the color temperature and intensity of ambient light; and

adjust, based on the output of the ambient light sensor, an output of at least one of an intensity and a color temperature of the array of LEDs, wherein

adjusting the output is performed by use of a communication link that is configured to allow communication between a portable electronic device and the lighting assembly, and

the portable electronic device comprises a camera.

2. The lighting system of claim 1 , further comprising an LED driver configured to supply current to the plurality of LEDs.

3. The lighting system of claim 2 , wherein the processor is further configured to independently control, using the LED driver, an amount of current supplied to each LED of the plurality of LEDs.

4. The lighting system of claim 1 , wherein the processor is further configured to:

detect an external pulse of light; and

in response to the detected external pulse of light, cause the plurality of LEDs to emit a pulse of light.

5. The lighting system of claim 1 , wherein the processor is further configured to:

receive camera exposure data from the portable electronic device; and

adjust, based on the camera exposure data, at least one of the color temperature and the intensity of the array of LEDs.

6. The lighting system of claim 1 , wherein the processor is further configured to:

receive user input from an application running on the portable electronic device; and

adjust, based on the user input, at least one of the color temperature and the intensity of the plurality of LEDs.

7. The lighting system of claim 1 , wherein the processor is further configured to:

receive a voice command from a user; and

adjust, based on the voice command, at least one of the color temperature and the intensity of the plurality of LEDs.

8. The lighting system of claim 1 , wherein the processor is further configured to independently control a color temperature and intensity of each LED of the plurality of LEDs.

9. The lighting system of claim 1 , wherein the plurality of LEDs are disposed on a first surface of a housing, wherein the housing further comprises a second surface disposed opposite the first surface, wherein the second surface comprises an opening for receiving the portable electronic device.

10. The lighting system of claim 9 , further comprising a second plurality of LEDs, wherein the second plurality of LEDs are disposed on the second surface of the housing.

11. The lighting system of claim 10 , wherein the second plurality of LEDs are configured to emit light in a second direction that is opposite the first direction.

12. An electronic device, comprising:

a camera;

a plurality of LEDs comprising RGB+WW LEDs;

an ambient light sensor configured to detect at least one of a color temperature and intensity of ambient light;

a processor configured to:

receive an output from the ambient light sensor, the output representative of the at least one of the color temperature and intensity of ambient light; and

adjust, based on the output of the ambient light sensor, the output of at least one of an intensity and a color temperature of the plurality of LEDs.

13. The electronic device of claim 12 , wherein the processor is further configured to independently control an amount of current supplied to each LED of the plurality of LEDs.

14. The electronic device of claim 12 , wherein the processor is further configured to:

receive camera exposure data from the camera; and

adjust, based on the camera exposure data, at least one of the color temperature and the intensity of the array of LEDs.

15. The electronic device of claim 12 , wherein the processor is further configured to:

receive user input from an application running on the electronic device; and

adjust, based on the user input, at least one of the color temperature and the intensity of the plurality of LEDs.

16. The electronic device of claim 12 , wherein the processor is further configured to:

receive a voice command from a user; and

adjust, based on the voice command, at least one of the color temperature and the intensity of the plurality of LEDs.

17. A method for controlling a lighting strobe system for use with a portable electronic device, the method comprising:

detecting at least one of a color temperature and an intensity of ambient light using an ambient light sensor;

setting at least one of a color temperature and an intensity of light to be emitted by a plurality of LEDs comprising RGB+WW LEDs, wherein setting at least one of a color temperature and an intensity of light to be emitted by the plurality of LEDs is performed by use of a communication link that is configured to allow communication between the lighting strobe system and the portable electronic device, and the portable electronic device comprising a camera; and

emitting light using the plurality of LEDs based on the set color temperature or the intensity.

18. The method of claim 17 , further comprising adjusting at least one of the color temperature and the intensity of light to be emitted by the plurality of LEDs based on camera exposure data.

19. The method of claim 17 , further comprising adjusting at least one of the color temperature and the intensity of light to be emitted by the plurality of LEDs based on commands received from an application running on the electronic device.

20. The method of claim 17 , further comprising adjusting at least one of the color temperature and the intensity of light to be emitted by the plurality of LEDs based on a voice command.
