Abstract
A thermal management system for extending the life and operational effectiveness of UVC LEDs utilized in an air disinfection device, includes a hollow airflow chamber having a first end and a second end on opposite sides of a length of the hollow airflow chamber; a fan configured to generate airflow through the airflow chamber; a UVC LED array coupled to a framework, the framework including cut-outs for airflow, and the framework is coupled to the hollow airflow chamber in the path of the airflow. An air disinfection system and ceiling light troffer fixture are described herein.
Claims20
A thermal management system for UVC LEDs utilized in an air disinfection device, comprising:
- an airflow chamber having a first end and a second end on opposite sides of a length of the airflow chamber;
- a fan configured to generate airflow through the airflow chamber;
- and
- a UVC LED array coupled to a framework, the framework including cut-outs for airflow, the cut-outs comprising a first cut-out and a second cut-out;
- the framework coupled to the airflow chamber in a path of the airflow;
- wherein UVC LEDs of the UVC LED array are configured to emit light in a longest direction of the airflow chamber;
- wherein the fan is coupled to the airflow chamber within 25% of a total length of the airflow chamber nearest the first end, and the UVC LED array is within 25% of the total length of the airflow chamber that is nearest the second end of the airflow chamber;
- and
- wherein a UVC LED of the UVC LED array is between a first heat spreader and a second heat spreader, the first heat spreader borders the first cut-out on a first side of the UVC LED and the second heat spreader borders the second cut-out on an opposite side of the UVC LED;
- and
- wherein at least one UVC LED is attached to at least one dedicated heat spreader that is not attached to another UVC LED;
- and
- wherein at least one dedicated heat spreader extend perpendicularly to a length direction of the airflow chamber on a protrusion of the framework into at least one of the cut-outs.
