Abstract

The disclosed technology relates to a hard and soft light module having a housing with a first surface that accommodates a lens. A first plurality of LEDs are disposed along a periphery of the first surface, the first plurality of LEDs are configured to generate light in a first direction toward an edge of the lens. A second plurality of LEDs are disposed proximate to the first surface, the second plurality of LEDs are configured to generate light in a second direction through the lens. The first plurality of LEDs are configured to generate a soft light and the second plurality of LEDs are configured to generate a hard light.

Claims (39)

1. A hard and soft light module, comprising:

a housing having a first surface, the first surface accommodating a lens;

a first plurality of LEDs disposed along a periphery of the first surface, wherein the first plurality of LEDs are configured to generate light in a first direction toward an edge of the lens; and

a second plurality of LEDs disposed proximate to the first surface, wherein the second plurality of LEDs are configured to generate light in a second direction through the lens.

2. The hard and soft light module of claim 1 , further comprising:

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, at least one of an intensity and color temperature of the first plurality of LEDs or the second plurality of LEDs.

3. The hard and soft light module of claim 2 , 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 first plurality of LEDs or the second plurality of LEDs to emit a pulse of light.

4. The hard and soft light module of claim 2 , wherein the processor is further configured to:

receive exposure data from a portable electronic device; and

adjust, based on the exposure data, at least one of the color temperature and intensity of the first plurality of LEDs or the second plurality of LEDs.

5. The hard and soft light module of claim 2 , wherein the processor is further configured to:

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

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

6. The hard and soft light module of claim 2 , 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 intensity of the first plurality of LEDs or the second plurality of LEDs.

7. The hard and soft light module of claim 2 , wherein the processor is further configured to independently control a color temperature and intensity of each LED of the first plurality of LEDs or the second plurality of LEDs.

8. The hard and soft light module of claim 1 , wherein the first plurality of LEDs are configured to emit light having a color temperature of 2400 Kelvin to 4000 Kelvin.

9. The hard and soft light module of claim 1 , wherein the second plurality of LEDs are configured to emit light having a color temperature of 4000 Kelvin to 8000 Kelvin.

10. The hard and soft light module of claim 1 , wherein the first plurality of LEDs are configured to project light at a distance of 1 foot to 2 feet.

11. The hard and soft light module of claim 1 , wherein the second plurality of LEDs are configured to project light at a distance of 6 feet to 12 feet.

12. The hard and soft light module of claim 1 , wherein the lens comprises a frosted lens; and wherein the first plurality of LEDs are disposed along a periphery of the frosted lens to illuminate the frosted lens.

13. A method for illuminating a subject using a hard and soft light module, the method comprising:

emitting light from a first plurality of LEDs disposed along a periphery of a first surface of a housing, wherein the first surface accommodates a lens, and wherein the first plurality of LEDs are configured to generate light in a first direction toward an edge of the lens; and

emitting light from a second plurality of LEDs disposed proximate to the first surface, wherein the second plurality of LEDs are configured to generate light in a second direction through the lens.

14. The method of claim 13 , further comprising:

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

adjusting at least one of a color temperature and intensity of light emitted by the first plurality of LEDs or the second plurality of LEDs, based on the detected color temperature or intensity of the ambient light.

15. The method of claim 14 , further comprising adjusting at least one of the color temperature and intensity of light emitted by the first plurality of LEDs or the second plurality of LEDs, based on exposure data.

16. The method of claim 14 , further comprising adjusting at least one of the color temperature and intensity of light emitted by the first plurality of LEDs or the second plurality of LEDs, based on commands received from an application running on an electronic device.

17. The method of claim 14 , further comprising adjusting at least one of the color temperature and intensity of light emitted by the first plurality of LEDs or the second plurality of LEDs based on a voice command.

18. The method of claim 13 , wherein the first plurality of LEDs are configured to emit light having a color temperature of 2400 Kelvin to 4000 Kelvin; and wherein the second plurality of LEDs are configured to emit light having a color temperature of 4000 Kelvin to 8000 Kelvin.

19. The method of claim 13 , wherein the first plurality of LEDs are configured to project light at a distance of 1 foot to 2 feet; and wherein the second plurality of LEDs are configured to project light at a distance of 6 feet to 12 feet.

20. The method of claim 13 , wherein the lens comprises a frosted lens; and wherein the first plurality of LEDs are disposed along a periphery of the frosted lens to illuminate the frosted lens.
