Abstract: A lighting device that includes a heat sink coupled to a heat dissipation structure. The heat dissipation structure can include heat conduits operatively coupled to a light emitting device to receive and emit heat from the light emitting device. The heat conduits conduct heat from the light emitting device to the heat sink that is disposed above the light emitting device to protect the internal components of the lighting device.

Abstract: An outdoor lighting system utilizing light-emitting diodes (LEDs) and structures to dissipate heat generated by the LEDs. The system includes a tubular enclosure housing an internal LED lighting assembly including LEDs mounted to a finned support structure which extends between two ends of the tube. At the end of the tube is at least one heat dissipating structure which is retained on the tubular enclosure by the threaded fastener. A heat dissipating structure in the form of a finned heat sink having an integrated, formed-in-place gasket abutting the end of the tubular enclosure.

Abstract: A lighting system utilizing light-emitting diodes (LEDs) and methods for configuring lanterns thereof are disclosed. The lantern includes a roof or canopy that includes fans that span directly between the electronics and LEDs for improved heat dissipation, the fans preferably formed integral with the canopy. The LEDs are mounted on easily mounted and removed modular printed circuit boards, in at least two different sizes and numbers of LEDs, and optical lenses of at least two different lighting patterns are provided, so that the lantern may be assembled or retrofit according to a desired application including candlepower and lighting pattern for cast light. The optical lenses are individually provided, utilize refraction to diminish reflection, and, in one form, incorporate an integral reflector to assist in defining a lighting pattern. In some forms, a securement may be provided for individual securement of lenses with the PCB.
