Abstract

The invention provides an elongated lighting fixture with multiple light emitting diodes (LEDs) arrayed in two groups that are angled to each other. The fixture provides an extremely broad light emitting angle and includes an elongated housing having a pair of side walls. Each side wall has a support member extending upward at angle from the side wall, wherein the side walls terminate at a central wall. A generally transparent cover is connected to the housing and extends between opposed ends of the housing. A first group of LEDs and a second group of LEDs are mounted to the first support member and the second support member, respectively. PCB boards assemblies are affixed to respective support members beneath the group of LEDs by tension clips. When the PCBs are energized by a power source, current travels from the PCBs to each LED for illumination.

Claims

1. An elongated LED light fixture comprising:

an elongated housing including a central hub extending longitudinally along the housing, a pair of opposed arms extending at an angle from the central hub, and at least one leg that extends rearward from the central hub, wherein the terminus of the arm has a curvilinear configuration that defines a recess;

a light engine including a printed circuit board and a plurality of LEDs electrically and mechanically connected to the circuit board, wherein the printed circuit board resides within a channel of the central hub; and

,

a lens cover residing within the recess for securement to the housing.

2. The LED light fixture of claim 1, wherein the arm has an inner reflecting surface that is oriented 10 to 15 degrees from horizontal.

3. The LED light fixture of claim 2, wherein the inner reflecting surface is oriented 12 degrees from horizontal.

4. The LED light fixture of claim 1, wherein the rear leg includes a curvilinear terminal recess that is configured to engage a support surface.

5. The LED light fixture of claim 1, wherein the housing includes two legs extending rearward from the central curvilinear outer surface, each leg including a curvilinear recess that is configured to engage a support surface.

6. The LED light fixture of claim 5, wherein the two legs are spaced a distance apart to define a rear cavity that extends longitudinally along the housing.

7. The LED light fixture of claim 1, wherein the printed circuit board comprises a plurality of inline boards electrically joined by a connector.

8. The LED light fixture of claim 1, further comprising an external power supply electrically connected to the circuit board, wherein the fixture has a low profile configuration.

9. The LED light fixture of claim 1, wherein the housing includes at least one angled support member, wherein the channel extends longitudinally along the support member.
