Abstract

A light source replacement for a fluorescent troffer light fixture utilizing light emitting diode and lens combination with the existing diffuser to produce lower contrast and evenly distributed illumination.

Claims (45)

1. A lenticular LED troffer fixture comprising:

a troffer comprising;

a transformer;

a diffuser; and

an LED module, the LED module comprising;

a module base;

a printed circuit board having an LED; and

a bezel having a lens which changes by refraction the light output pattern of said LED;

wherein the troffer comprises a trough further comprising a back plate and wherein the LED module is attached to the back plate of the troffer within the trough.

2. The lenticular LED troffer fixture of claim 1 wherein the printed circuit board includes multiple LEDs.

3. The lenticular LED troffer fixture of claim l wherein the bezel includes multiple lenses.

4. The lenticular LED troffer fixture of claim l, and further comprising a spacer that is attached to the back plate of the troffer within the trough, and wherein the LED module is attached to a spacer.

5. The lenticular LED troffer fixture of claim 4 , and further comprising a quick mount, wherein the LED module is attached to a spacer that is in turn attached to the back plate of a troffer within the trough by the quick mount.

6. The lenticular LED troffer fixture of claim 1 , and further comprising a quick mount, wherein the LED module is attached to back plate of the troffer within the trough by the quick mount.

7. The lenticular LED troffer fixture of claim l wherein multiple LED modules are contained within the trough of the troffer.

8. The lenticular LED troffer fixture of claim l wherein the LED and lens are held in relation to one another by the module base.

9. The lenticular LED troffer fixture of claim 8 wherein the printed circuit board is held in place by the bezel.

10. The lenticular LED troffer fixture of claim l, and further comprising end caps of the module base, wherein the LED and lens are held in relation to one another by the module base with the assistance of end caps.

11. The lenticular LED troffer fixture of claim 10 wherein the printed circuit board is held in place by the bezel with the assistance of end caps.

12. The lenticular LED troffer fixture of claim l, and further comprising a bezel flange of the module base to retain the bezel.

13. The lenticular LED troffer fixture of claim l wherein the LED comprises a high intensity LED.

14. The lenticular LED troffer fixture of claim l wherein the lens changes by refraction the light output of the LED to a wider distribution of light onto the diffuser.

15. A lenticular LED troffer fixture comprising:

a troffer comprising;

a transformer;

a diffuser; and

an LED module, the LED module comprising;

a module base;

a printed circuit board having an LED; and

a bezel having a lens which changes by refraction the light output pattern of said LED;

wherein a distribution of light onto the diffuser consists of a large variety of small and overlapping bright areas.

16. The lenticular LED troffer fixture of claim 15 wherein the large variety of small and overlapping bright areas creates a general illumination similar to the glow of a fluorescent troffer fixture.

17. The lenticular LED troffer fixture of claim 15 wherein the light created by the LED and refracted by the lens creates a distinct pattern on the diffuser.

18. A lenticular troffer fixture comprising:

a troffer comprising:

a back plate;

a trough formed by a concavity of the troffer sides; and

a retaining flange that retains the diffuser;

a transformer attached to the back plate within the trough;

a diffuser that redistributes light in an even distribution;

a pair of LED modules, each attached to the back plate within the trough, each module comprising:

a printed circuit board having multiple LEDs;

a bezel, including multiple lenses which change, by refraction, the light output pattern of said LEDs;

a module base that retains the printed circuit board and bezel in a specific relation to each other; and

a pair of end caps that assists the module base in retaining the printed circuit board and bezel in a specific relation to each other.
