Abstract
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.
Claims20
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.
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.
