Abstract

A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

Claims

1. The combination fan and light fixture comprising:

a housing having the dimensions of a ceiling tile, said housing comprising a lighting section and a separate fan section wherein the lighting section does not overlap the fan section;

a fan positioned within the housing in the fan section forming a fan cavity; and

an LED light fixture positioned within the housing in the lighting section forming a lighting cavity, wherein the fan operates to direct air from the fan cavity to the lighting cavity such that a portion of the air is propelled around the LED lighting fixture to dissipate heat from the LED light fixture.

2. The combination fan and light fixture of claim 1 further comprising a diffuser in the fan portion to direct air from the fan section to the lighting section.

3. The combination fan and light fixture of claim 2 further comprising a lens positioned in the lighting section.

4. The combination fan and light fixture of claim 3 further comprising a louvre to direct air from the fan section toward the LED light fixture.

5. The combination fan and light fixture of claim 1 further comprising a filter positioned within the fan section of the housing.

6. The combination fan and light fixture of claim 4 wherein the lens comprising a color selected from the group of red, blue, green and yellow.

7. The combination fan and light fixture of claim 4 wherein a LED light in the LED light fixture comprising a color selected from the group of red, blue, green and yellow.

8. The combination fan and light fixture of claim 1 further comprising an exit vent positioned in the lighting section.

9. A combination fan and light fixture comprising:

a housing;

a fan positioned within the housing including an inlet and an outlet;

wherein the fan and the housing are configured to form a fan chamber;

an air diversion mechanism positioned within the fan chamber, whereby the air diversion mechanism causes air circulated by said fan to be distributed into a lighting chamber;

an LED light fixture affixed to the housing in the lighting chamber such that the fan does not disrupt light illuminating from the LED light fixture and to receive airflow along said airflow surface to reduce the temperature of the LED light fixture; and

a lower housing portion of the housing having an airflow surface, said airflow surface positioned to direct air within the housing from the fan cavity along the LED light fixture.

10. The combination fan and light fixture of claim 9 further comprising a lens affixed to the housing.

11. The combination fan and light fixture of claim 10 wherein the lens comprising of a color selected from the group consisting of red, blue, green and yellow.

12. The combination fan and light fixture of claim 9 further including an inner lining wherein the inner lining is a color selected from the group of red, blue, green and yellow.

13. The combination fan and light fixture of claim 9, further including a filter positioned in the fan chamber.

14. The combination fan and light fixture of claim 13 wherein the diversion mechanism direct air flow across the LED light fixture.

15. A combination fan and light fixture comprising:

a housing including a troffer which form a troffer cavity;

a fan positioned within the housing including a fan support attaching the fan to the housing and forming a fan chamber;

a diffuser positioned in the fan support to direct air from the fan chamber into a troffer cavity;

a light fixture affixed to the troffer, wherein the lighting fixture is positioned within the troffer cavity to permit air flowing from the diffuser to contact the light fixture.

16. The combination fan and light fixture of claim 15 further comprising a filter positioned in proximity to the fan.

17. The combination fan and light fixture of claim 15 wherein the light fixture comprising an LED light fixture.

18. The combination fan and light fixture of claim 17 wherein the light fixture is positioned such that the fan does disrupt the light illuminating from the light fixture.

19. The combination fan and light fixture of claim 15 wherein the diffuser is prism shaped.

20. The combination fan and light fixture of claim 15 wherein the diffuser is triangular shaped.
