Abstract

Light emitting device (LED) circuit board layouts for low profile lighting fixtures are provided. In some embodiments, the lighting fixture can include a fixture housing. The lighting fixture can include one or more LED devices disposed on a circuit board. The lighting fixture can include one or more electronic components associated with at least one of a driver circuit or a filter circuit (e.g., as part of a flicker reducing circuit) disposed on the circuit board. The one or more LED devices are disposed on a first portion of the circuit board and the electronic components are disposed on a second portion of the circuit board. The second portion of the circuit board can be spaced radially apart from a center point of the circuit board relative to the first portion.

Claims (33)

1. A lighting fixture, comprising:

a housing having depth dimension and a length dimension, wherein the depth dimension is less than the length dimension;

a circuit board positioned in the housing;

one or more LEDs disposed on a central portion of the circuit board, the one or more LEDs extending a first distance from the circuit board;

a driver circuit disposed on the peripheral portion of the circuit board; and

a filter circuit disposed on the peripheral portion of the circuit board, the filter circuit comprising one or more capacitors extending a second distance from the circuit board, the second distance being greater than the first distance,

wherein the second portion is spaced from the first portion a sufficient distance to reduce a shadowing effect in light emitted from the LEDs.

2. The lighting fixture of claim 1 , wherein an output of the driver circuit is provided to the one or more capacitors.

3. The lighting fixture of claim 2 , wherein the driver circuit is a dimmable driver circuit.

4. The lighting fixture of claim 1 , further comprising a lens connected to the housing and positioned such that light emitted from the one or more LEDs passes through the lens.

5. The lighting fixture of claim 1 , further comprising a fuse positioned on the circuit board.

6. The lighting fixture of claim 1 , wherein the second distance is at least two times greater than the first distance.

7. The lighting fixture of claim 1 , wherein least one of the driver circuit and the filter circuit partially surrounds the LEDs.

8. The lighting fixture of claim 7 , wherein the one or more LEDs include a plurality of LEDs positioned on the circuit board in a circular array.

9. The lighting fixture of claim 1 , wherein the filter circuit is associated with a flicker reducing circuit.

10. The lighting fixture of claim 1 , wherein the driver circuit outputs a DC power supply.

11. The lighting fixture of claim 1 , wherein the circuit board is mounted to a heat sink.

12. A surface mount, low profile lighting fixture, comprising:

a housing having depth dimension and a length dimension, wherein the depth dimension is less than the length dimension;

a surface mounting fastener connected to the housing;

a circuit board positioned in the housing;

one or more LEDs disposed on a central portion of the circuit board, the one or more LEDs extending a first distance from the circuit board;

a driver circuit disposed on the peripheral portion of the circuit board; and

a filter circuit disposed on the peripheral portion of the circuit board, the filter circuit comprising one or more capacitors extending a second distance from the circuit board, the second distance being greater than the first distance,

wherein the second portion is spaced from the first portion a sufficient distance to reduce a shadowing effect in light emitted from the LEDs.

13. The lighting fixture of claim 12 , wherein an output of the driver circuit is provided to the one or more capacitors.

14. The lighting fixture of claim 12 , further comprising a lens positioned such that light emitted from the one or more LEDs passes through the lens.

15. The lighting fixture of claim 12 , wherein the surface mounting fastener includes a spring clip.

16. The lighting fixture of claim 12 , wherein the second distance is at least two times greater than the first distance.

17. The surface mount, low profile lighting fixture of claim 12 , wherein the filter circuit is spaced radially apart from the central portion of the circuit board.

18. The surface mount, low profile lighting fixture of claim 12 , wherein the second portion extends at least 180 degrees radially around the first portion.

19. The surface mount, low profile lighting fixture of claim 12 , further comprising a waterproof gasket positioned to seal between the housing and a mounting surface.

20. The surface mount, low profile lighting fixture of claim 12 , wherein the circuit board is mounted to a heat sink.
