US Patent 10359187 Heating unit with LEDs and venting

A heating unit includes a housing defining a thermal cavity and has a first longitudinal edge and an opposing second longitudinal edge, a reflector assembly disposed within the thermal cavity, a heating element, and a lighting element. The housing defines a vent positioned at least one of laterally between a central longitudinal plane of the housing and the first longitudinal edge and laterally between the central longitudinal plane and the opposing second longitudinal edge. The reflector assembly is coupled to an interior surface of the housing. A spacer is positioned between the reflector assembly and the interior surface forming an air gap therebetween. The heating element extends within the central longitudinal plane and is at least partially surrounded by the reflector assembly. The lighting element is positioned along at least one of the first longitudinal edge and the opposing second longitudinal edge such that the vent is positioned laterally between the lighting element and the heating element.
