Abstract

A LED assembly includes a baseplate and a diffuser. A circuit board connected to the baseplate has a first set of LEDs directed to emit light toward the diffuser. Additionally, a frame is attached to the baseplate and positioned to surround the circuit board. A flexible circuit with a second set of LEDs is attached to the frame, with the LEDs positioned to emit light predominantly perpendicular with respect to the first set of LEDs.

Claims (28)

1. A light emitting diode (LED) assembly, comprising:

a baseplate and a diffuser;

a circuit board connected to the baseplate and having a first set of LEDs directed to emit light toward the diffuser;

a hollow, integrally formed annular frame attached to the baseplate and positioned to surround the circuit board and extend beyond a top-most extent of the first set of LEDs;

a flexible circuit strip with a second set of LEDs attached thereto, attached to the frame so as to surround the circuit board, with the second set of LEDs positioned to emit light predominantly perpendicular with respect to the first set of LEDs.

2. The LED assembly of claim 1 , wherein the circuit board and the frame are positioned in a center of the baseplate.

3. The LED assembly of claim 1 , wherein the diffuser, circuit board, and baseplate are circular.

4. The LED assembly of claim 1 , wherein the first and second set of LEDs are connected to each other in parallel.

5. The LED assembly of claim 1 , wherein the first and second set of LEDs have the same number of LEDs.

6. The LED assembly of claim 1 , wherein color of the first and second set of LEDs is adjustable.

7. The LED assembly of claim 2 , wherein ends of the flexible circuit strip are attached to each other.

8. The LED assembly of claim 7 , wherein ends of the flexible circuit strip further comprise solder pads.

9. The LED assembly of claim 8 , wherein ends of the flexible circuit strip further comprise tabs extending perpendicular from a longitudinal axis of the flexible circuit strip and include (i) solder pads coupled to each other and (ii) further solder pads coupled to a power and control module.

10. The LED assembly of claim 9 , wherein the first and second set of LEDs are connected to a power and control module, the power and control module situated on an opposing side of the baseplate as the circuit board, first set of LEDs, the frame, and second set of LEDs.

11. The lighting system of claim 10 , wherein the first direction is substantially perpendicular with respect to the second direction.

12. The lighting system of claim 10 , wherein the frame and the circuit board are attached to a baseplate.

13. The lighting system of claim 10 , wherein the first and second set of LEDs are connected to each other in parallel.

14. The lighting system of claim 10 , wherein the first and second set of LEDs have the same number of LEDs.

15. The lighting system of claim 10 , wherein color of the first and second set of LEDs is adjustable.

16. The lighting system claim 10 , wherein ends of the flexible circuit strip are attached to each other.

17. The lighting system of claim 10 , wherein ends of the flexible circuit strip further comprise solder pads.

18. The lighting system of claim 17 , wherein ends of the flexible circuit strip further comprise tabs extending perpendicular from a longitudinal axis of the flexible circuit strip and include (i) solder pads coupled to each other and (ii) further solder pads coupled to a power and control module.

19. The lighting system of claim 12 , wherein the power and control module further comprises a connectivity module and a color tuning module, the power and control module situated on an opposing side of the baseplate as the circuit board, first set of LEDs, the frame, and second set of LEDs.

20. A lighting system, comprising:

a power and control module;

a circuit board with a first set of light emitting diodes (LEDs) directed to emit light in a first direction;

a hollow, integrally formed annular frame positioned to surround the circuit board and extend beyond a top-most extent of the first set of LEDs;

a flexible circuit strip with a second set of LEDs attached thereto, attached to the frame so as to surround the circuit board, with the second set of LEDs positioned to emit light at a second direction distinct with respect to the first set of LEDs.
