LED luminaire with multiple vents for promoting vertical ventilation

摘要

Some features of the invention include a LED luminaire, including a chassis having a chassis body, the chassis body having an inner perimeter and an outer perimeter. At least one LED lighting module is mounted on the chassis body. A LED power supply assembly includes at least one LED power supply unit for the at least one LED lighting module. The LED luminaire further includes at least one inner perimeter vent interposed between the chassis body and the LED power supply assembly to thermally separate the chassis body from the LED power supply assembly. Outer perimeter vents may be located along the outer perimeter. The inner and outer perimeter vents promote the natural flow of air around and through the LED luminaire to remove heat generated by the at least one LED lighting module and/or LED power supply assembly. In certain features, the LED power supply assembly includes top and bottom vent covers, and the at least one LED power supply unit is located between the top and bottom vent covers. The top and bottom vent covers are vented to promote the natural flow of air through the LED power supply assembly, further removing heat generated by the at least LED one power supply unit. Yet other features include a shaped optic covering the at least one LED lighting module and that further promotes the natural flow of air around and through the LED luminaire.
