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. The invention includes a vented mechanical equipment casing configured to include an opening to direct a portion of the air exiting the fan cavity into an equipment chamber housing the mechanical equipment and configured to direct the air to encounter the mechanical equipment and operate to reduce the temperature of the equipment. ## Claims ### Claim 1 An air movement and recirculation device comprising: a housing, said housing including a fan chamber, a troffer cavity positioned in proximity to the fan chamber; the housing including a frame; a first fan positioned in the housing within a fan cavity wherein the fan rotates in a first direction to generate an air flow into the fan chamber, the fan aligned with a fan intake grill in the housing; a vented mechanical equipment casing affixed to the housing in proximity of the fan cavity wherein the vented mechanical equipment casing includes a first openings configured to divert a portion of the air exiting the fan chamber into the troffer cavity; an LED light fixture having a determined temperature affixed to the housing and positioned in the troffer cavity wherein a portion of the LED light fixture is positioned within the troffer cavity and the troffer cavity configured to direct a flow of the air from the fan chamber such that the flow of air operates to cool the LED light fixture; and the vented mechanical equipment casing configured to form an equipment chamber wherein the vented mechanical equipment casing houses mechanical equipment associated with the LED light fixture positioned in the equipment chamber, the mechanical equipment having a predetermined temperature; the vented mechanical equipment casing configured to include an opening to direct a portion of the air of the air exiting the fan chamber into the equipment chamber wherein the flow of air into the equipment chamber is directed to encounter the equipment and operates to reduce the predetermined temperature of the equipment. ### Claim 2 (depends on 1) The air movement and recirculation device of claim 1, wherein the housing has the dimensions of a ceiling tile. ### Claim 3 (depends on 1) The air movement and recirculation device of claim 1, wherein the housing has a length and a width in the dimensions of a ceiling tile, wherein the width is 2 feet, and the length is 4 feet. ### Claim 4 (depends on 1) The air movement and recirculation device of claim 1, wherein the opening in the vented mechanical equipment casing is a plurality of vents. ### Claim 5 (depends on 1) The air movement and recirculation device of claim 1, wherein the opening in the vented mechanical equipment casing is a plurality of slots. ### Claim 6 (depends on 1) The air movement and recirculation device of claim 1, wherein the opening in the vented mechanical equipment casing is a plurality of perforations. ### Claim 7 (depends on 1) The air movement and recirculating device of claim 1, wherein the vented mechanical equipment casing is configured in a pyramidal shape. ### Claim 8 (depends on 1) The air movement and recirculating device of claim 1, wherein the vented mechanical equipment casing is configured in a cone shape. ### Claim 9 (depends on 1) The air movement and recirculating device of claim 1, wherein the vented mechanical equipment casing is configured in a triangular shape. ### Claim 10 (depends on 1) The air movement and recirculating device of claim 1, further comprising an LED light cover affixed to the housing configured to include an opening in the cover to allow for air to exit from the air chamber. ### Claim 11 (depends on 10) The air movement and recirculating device of claim 10, wherein the opening in the LED light cover comprises a plurality of perforations. ### Claim 12 An air movement and recirculation device comprising: a housing adaptable to be mounted in a ceiling tile grid; a ceiling tile material secured to the housing, said ceiling tile material is configured to include an air intake grill in the ceiling tile material and a vent in the ceiling tile material; a troffer shell affixed to the housing configured to create fan chamber, a troffer cavity, wherein the troffer cavity is aligned with the vent of the ceiling tile material; a fan affixed to the housing, the fan aligned with the air intake grill of the ceiling tile material and the fan having a fan outlet; a vented mechanical equipment casing positioned at the outlet of the fan, wherein the vented mechanical equipment casing is configured to include a first plurality of openings configured to divert a portion of the air exiting the fan outlet into troffer cavity and a second plurality of openings configured to divert a portion of the air exiting the fan outlet into an equipment chamber configured by the vented mechanical equipment casing; an LED light fixture having a determined temperature, positioned in the ceiling tile material and configured such that a portion of the LED light fixture is located in the troffer cavity whereby the air directed form the fan outlet into the troffer cavity passes the portion of the LED light fixture located in the troffer cavity thereby reducing the temperature of the LED light fixture; and the vented mechanical equipment casing houses mechanical equipment associated with an LED light fixture positioned in the equipment chamber, the mechanical equipment having a predetermined temperature; the vented mechanical equipment casing configured to include an opening to direct a portion of the air of the air exiting the fan chamber into the equipment chamber wherein the flow of air into the equipment chamber is directed to encounter the equipment and operates to reduce the predetermined temperature of the equipment. ### Claim 13 (depends on 12) The air movement and recirculation device of claim 12, wherein the opening in the vented mechanical equipment casing is a plurality of vents. ### Claim 14 (depends on 12) The air movement and recirculation device of claim 12, wherein the opening in the vented mechanical equipment casing is a plurality of slots. ### Claim 15 (depends on 12) The air movement and recirculation device of claim 12, wherein the opening in the vented mechanical equipment casing is a plurality of perforations. ### Claim 16 (depends on 12) The air movement and recirculating device of claim 12, wherein the air vented mechanical equipment casing is configured in a pyramidal shape. ### Claim 17 (depends on 12) The air movement and recirculating device of claim 12, wherein the air vented mechanical equipment casing is configured in a cone shape. ### Claim 18 (depends on 12) The air movement and recirculating device of claim 12, wherein the air vented mechanical equipment casing is configured in a triangular shape.
