Patent ID: 8042978

Claim:
A light emitting assembly comprising a first and a second plate each including opposed first and second surfaces, the first and second plates being arranged in alignment along a substantially longitudinal axis, the longitudinal axis being configured for positioning in substantial alignment with a direction of gravity in use, the second surface of the second plate being arranged so as to extend substantially across the first surface of the first plate in a substantially transverse direction relative to the longitudinal axis; a first and a second light emitting source disposed on the first surfaces of the first and second plates respectively, said first and second light emitting sources being adapted to emit light substantially in a primary light emission direction, said primary light emission direction including a substantially perpendicular direction relative to the longitudinal axis; at least one elongate arm for supporting the first and second plates, ends of the first and second plates being mounted to the at least one elongate arm wherein at least one of the first and second plates is arranged at an angle of less than 90 degrees relative to the longitudinal axis; and wherein the first and second plates and the elongate arm collectively define an airflow passage having an inlet and an outlet disposed on opposing ends of the airflow passage, whereby air is able to enter the airflow passage via the inlet to dissipate heat generated by the light emitting sources, pass through the airflow passage, and exit via the outlet to transfer heat away from the light emitting sources.
