Abstract
A lighting system or luminaire can comprise two environmentally sealed housings. One of the housings can house one or more light emitting diodes. The other housing can house a driver for supplying electricity to the light emitting diode or diodes. The housings can be nested together. For example, one of the housings can extend partially into a cavity of the other housing. A portion of the cavity can remain unfilled when the housings are nested, to provide an air gap between the two housings. The air gap can be environmentally exposed, for example exposed to moisture when the lighting system is mounted outdoors.
Claims19
A lighting system comprising:
- a first housing comprising at least one light emitting diode (LED) disposed therein;
- a second housing comprising an LED driver disposed therein,
- wherein the second housing is partially disposed in a cavity defined by the first housing such that a portion of an outside surface of the second housing and a portion of an outside surface of the first housing form an air gap therebetween;
- and
- a first set of heat sink fins projecting into the air gap from the portion of the outside surface of the first housing towards the portion of the outside surface of the second housing and spaced apart from the portion of the outside surface of the second housing.
The lighting system of claim 1, further comprising mounting hardware configured for attaching to an end of a pole.
A lighting system comprising:
- a first housing comprising at least one light source disposed therein;
- a second housing comprising a driver associated with the at least one light source disposed therein,
- wherein the second housing is nested in a cavity defined by the first housing to form an uninterrupted environmentally exposed air gap between the first housing and the second housing;
- an access door that is coupled to the second housing and comprising a first surface and an opposite second surface,
- wherein the access door is coupled to the second housing such that the first surface encloses the second housing and the opposite second surface is environmentally exposed,
- wherein the opposite second surface comprises heat sink fins disposed thereon to dissipate heat generated by the driver, and
- wherein the driver is attached to the first surface;
- and
- a gasket disposed in between the access door and the second housing such that the gasket thermally insulates the access door from heat generated by the at least one light source and transferred from the first housing comprising the at least one light source to the second housing through a portion of the second housing that is in thermal contact with the first housing.
