Abstract

Systems and methods for a high output, high color quality light are disclosed. In some embodiments, such a light may include a light fixture including one or more LEDs configured to output a cumulative light output; wherein the cumulative light output comprises an intensity of greater than or equal to 10,000 lumens; and wherein the cumulative light output comprises a CRI of at least 90.

Claims (34)

1. A light fixture comprising:

a plurality of LEDs configured to output a cumulative light output, the plurality of LEDs comprising a first plurality of LEDs connected in parallel with a second plurality of LEDs;

a switching regulator configured to balance a current provided to each of the first plurality of LEDs and the second plurality of LEDs;

wherein the cumulative light output comprises an intensity of greater than or equal to 10,000 lumens; and

wherein the cumulative light output comprises a CRI of at least 90.

2. The light fixture of claim 1 , wherein the cumulative light output comprises a color temperature of greater than or equal to 4000° K.

3. The light fixture of claim 1 , wherein the cumulative light output comprises a color temperature of greater than or equal to 5000° K.

4. The light fixture of claim 1 , wherein the light fixture is configured to operate based on a drive current, and wherein the drive current comprises at least 700 mA.

5. The light fixture of claim 4 , wherein the cumulative light output comprises an intensity of greater than or equal to 19,000 lumens.

6. The light fixture of claim 4 , wherein the cumulative light output comprises an intensity of greater than or equal to 38,000 lumens.

7. The light fixture of claim 4 , wherein the cumulative light output comprises an intensity of greater than or equal to 43,000 lumens.

8. The light fixture of claim 1 , wherein the light fixture is configured to operate based on a drive current, and wherein the drive current comprises at least 1000 mA.

9. The light fixture of claim 8 , wherein the cumulative light output comprises an intensity of greater than or equal to 13,000 lumens.

10. The light fixture of claim 8 , wherein the cumulative light output comprises an intensity of greater than or equal to 26,000 lumens.

11. The light fixture of claim 8 , wherein the cumulative light output comprises an intensity of greater than or equal to 50,000 lumens.

12. The light fixture of claim 8 , wherein the cumulative light output comprises an intensity of greater than or equal to 58,000 lumens.

13. The light fixture of claim 1 , wherein the CRI comprises a range from 90-94, the cumulative light output comprises an intensity in the range of 10,000 lumens to 56,816 lumens, and wherein the light fixture is configured to operate based on a drive current comprising a current within the range of 700 mA to 1000 mA.

14. A light fixture comprising:

a plurality of LEDs configured to output a cumulative light output at an efficiency, the plurality of LEDs comprising a first plurality of LEDs connected in parallel with a second plurality of LEDs;

a switching regulator configured to balance a current provided to each of the first plurality of LEDs and the second plurality of LEDs;

wherein the cumulative light output comprises a CRI of at least 90;

wherein the cumulative light output comprises at least 10,000 lumens; and

wherein the efficiency comprises at least 100 lumens per watt.

15. The light fixture of claim 14 , wherein the cumulative light output comprises a color temperature of greater than or equal to 4000° K.

16. The light fixture of claim 14 , wherein the light fixture is configured to operate based on a drive current, and wherein the drive current comprises at least 700 mA.

17. The light fixture of claim 16 , wherein the cumulative light output comprises an intensity of greater than or equal to 10,000 lumens.

18. The light fixture of claim 16 , wherein a total radiant flux of the light output comprises at least 30,900 mW.

19. The light fixture of claim 16 , wherein the efficiency comprises at least 109 lumens per watt.

20. The light fixture of claim 16 , wherein an input wattage comprises at least 93 Watts.

21. The light fixture of claim 14 , wherein the light fixture is configured to operate based on a drive current, and wherein the drive current comprises at least 1000 mA.

22. The light fixture of claim 21 , wherein the cumulative light output comprises an intensity of greater than or equal to 13,000 lumens.

23. The light fixture of claim 21 , wherein a total radiant flux of the light output comprises at least 40,000 mW.

24. The light fixture of claim 21 , wherein an input wattage comprises at least 130 Watts.

25. The light fixture of claim 14 , wherein the CRI comprises a range from 90-94, the cumulative light output comprises an intensity in the range of 10,000 lumens to 56,816 lumens, and wherein the efficiency is within the range of 100 lumens per watt to 105 lumens per watt.
