Abstract
A lighting device contains a plurality of light emitting sources mounted on a thermally conductive housing and electrically connected to a circuit board. The housing includes a base portion which is spaced apart from the circuit board, and an intermediate heat dissipation structure which is disposed between the circuit board and the base portion of the housing, for promoting cooling by convection. The plurality of light emitting sources are in thermal communication with the intermediate heat dissipation structure.
