Abstract

The present invention describes light fixtures comprising an array of self-contained LED tiles for illuminating light from a surface area of a respective light fixture. Each of the array of LED tiles is a self-contained lamp that contains its respective own AC or DC input power supply and LED driver, its respective heat dissipation element, and its respective light collation element. The array of tiles makes the total illumination from the array to be sufficiently bright, even though any given LED tile might only have a modest amount of light output. Embodiments of the LED tiles for use with various lamp fixtures include, but not limited to, a hexagon-shaped LED tile, a square-shaped LED tile, an equilateral triangle-shaped LED tile, and a rectangle-shaped LED tile with an aspect ratio, for example, of 3:1. The different types of LED tiles are suitable for use to cover various types of surfaces of lamp fixtures.

Claims

a surface area for illumination;

a plate assembly spaced apart from the surface area having a plurality of sockets; and

a plurality of individually replaceable LED tiles, each LED tile coupled to a corresponding socket, the plurality of individually replaceable LED tiles extending from the socket to form a lighting surface for projecting light.

2. The lighting apparatus of claim 1, wherein the surface comprises an open face.

3. The lighting apparatus of claim 1, wherein the surface comprises a plane.

4. The lighting apparatus of claim 1, wherein the surface comprises a cylindrical-shaped surface.

5. The lighting apparatus of claim 1, wherein the surface comprises a trapezoidal-shaped surface.

7. The lighting apparatus of claim 1, wherein each of the plurality of individually replaceable LED tiles comprises a trapezoidal-shaped LED tile.

8. The lighting apparatus of claim 1, wherein each of the plurality of individually replaceable LED tiles comprises a rectangular-shaped LED tile.

9. The lighting apparatus of claim 1, wherein each of the plurality of individually replaceable LED tiles comprises a triangular-shaped LED tile.

10. The lighting apparatus of claim 1, wherein each of the plurality of individually replaceable LED tiles comprises a circular-shaped LED tile.

11. The lighting apparatus of claim 1, wherein each LED tile comprises an AC power supply and LED driver, coupled to a respective LED tile, for driving a DC signal to the respective LED.

12. The lighting apparatus of claim 1, wherein each LED tile comprises a DC power supply and LED driver, coupled to a respective LED tile, for driving a DC signal to the respective LED tile.

13. The lighting apparatus of claim 1, wherein each LED tile comprises vent holes for cooling the LED tile.

14. The lighting apparatus of claim 1, wherein each LED tile comprises a plurality of LEDs.

15. The lighting apparatus of claim 1, wherein each LED tile comprises at least an LED, a heat sink, a light collator and a connector.

16. The lighting apparatus of claim 1, wherein the plate assembly comprises of sockets for receiving a plurality of LED tiles, a connector to couple to a supply source and wires to couple the sockets to the connector.

17. The lighting apparatus of claim 17, wherein the supply source is an AC.

18. The lighting apparatus of claim 17, wherein the supply source is a DC.

19. The lighting apparatus of claim 17, wherein the plate assembly further comprises at least a power supply.
