Abstract: There is provided a mounting bracket for attaching a light fixture to a light pole, with the light pole having an external surface, an internal surface defining an internal cavity, and a pair of apertures extending from the external surface to the internal surface. The mounting bracket includes an internal support sized and structured to be insertable within the internal cavity of the light pole. The internal support includes a housing and a pair of fasteners moveable relative to the housing and alignable with respective ones of the pair of apertures. An external support is sized and structured to be positionable adjacent the external surface of the light pole, the external support having a pair of slots formed therein and alignable with respective ones of the pair of fasteners. A mount body is slidably engageable with the external support and is pivotally connectable to the light fixture.

Abstract: A heat dissipating LED light bar which may be used as part of a complete retrofit system for a variety of linear fluorescent light fixtures. The LED light bar comprises an elongate channel member which is preferably fabricated from extruded aluminum. In addition to the channel member, the LED light bar comprises a high-efficacy set of LEDs, which are preferably provided in the form of an elongate LED printed circuit board (PCB) or strip mechanically bonded to the channel member. The channel member is outfitted with fins and other surface features uniquely configured to provide superior heat dissipation, thus allowing the channel member to effectively function as a heat sink for the LED strip cooperatively engaged thereto. Further, the channel member is configured to define an air flow cavity under the LED strip as allows for the effective dissipation of heat during operation of the LED light bar.

Abstract: A heat dissipating and optically efficient LED high bay light bar which may be used as part of a complete retrofit system for a variety of linear fluorescent light fixtures.
