Ceiling tile with built-in air flow mechanism and UV air purifying device
Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include 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 inventions include an airflow surface to direct air existing the fan cavity along an LED light fixture. Moreover, disclosed embodiments include one or more UV light sources which irradiate contaminants as air flows through the ceiling tile.
1. An air purifying device, comprising:
a ceiling tile having at least one vent and one fan portion;
an upper cover attached to the ceiling tile defining at least an airway between the fan portion and the vent;
a fan positioned in the fan portion adapted to guide air to the airway;
a UV light source mounted in the airway, wherein the UV light source is a UV-C light source emitting light having a wavelength between 200 and 280 nanometers;
a first baffle positioned in the airway and a second baffle positioned in the airway, wherein the first baffle and second baffle are configured to direct air guided by the fan to the airway along the UV light source; and
wherein the first baffle and the second baffle are positioned in the first airway to act as a barrier preventing light emitted from the UV light source from exiting the air purifying device.
2. The air purifying device of claim 1 , wherein the first baffle accommodates a UV reflective material.
3. The air purifying of claim 2 , wherein the second baffle accommodates a UV reflective material.
4. The air purifying device of claim 1 , wherein the cover includes a UV reflective material.
5. The air purifying device of claim 1 , wherein the ceiling tile includes a UV reflective material.
6. The air purifying device of claim 4 , wherein the ceiling tile includes a UV reflective material.
7. The air purifying device of claim 1 , wherein the first baffle and second baffle create a kill zone which kills bacteria, viruses or microbes present in the air guided by the fan to the airway.
8. The air purifying device of claim 2 , further comprising a second fan mounted to the fan portion of the ceiling tile and in-line with the first fan.
9. The air purifying device of claim 8 , wherein the first and second fan are configured to rotate in opposite directions.
10. The air purifying device of claim 1 , further comprising an LED light source affixed to the ceiling tile.
11. The air purifying device of claim 1 , further comprising an actuator to control the operation of the UV light source.
12. The air purifying device of claim 11 , wherein the actuator is a remote control unit.
13. The air purifying device of claim 1 , further comprising an indicator light source providing a visual indication when the UV light source is operating.
14. An air purifying device comprising:
a face-plate configured the size of a ceiling tile, wherein the face-plate includes a fan portion and a vent portion;
a cover attached to the face-plate forming an air chamber between the face-plate and the cover;
a fan positioned in the fan portion of the face-plate, wherein said fan directs air through the air chamber to the vent portion;
a UV-C light fixture positioned in the air chamber wherein the UV-C light fixture emits UV light to form a kill zone within the air chamber; and
a baffle positioned in proximity to the kill zone in the air chamber wherein the baffle is configured to direct air to the kill zone and prohibit the UV light from exiting the kill zone.
15. The air purifying device of claim 14 , further comprising a LED light positioned on the face-plate.
16. The air purifying device of claim 14 , wherein the UV-C light source emits UV-C light waves having a wavelength between 200 and 280 nanometers.
17. The air purifying device of claim 16 , wherein the UV-C light source operates to kill at least 99% of K. pneumoniae from the air.
18. The air purifying device of claim 14 , further comprising a second baffle positioned in the air chamber attached to the housing and wherein the second baffle directs air to the kill zone.
19. The air purifying device of claim 14 , wherein UV-C light fixture emits light capable of killing bacteria, viruses and microbes.
20. The air purifying device of claim 18 , further comprising a third baffle positioned in the air chamber wherein at least one of the baffle or the second baffle accommodates a UV-reflective material.
