Abstract
A lighting apparatus includes a light source module and a heat dissipation module. The light source module emits light and generates heat. The heat dissipation module dissipates at least a portion of the heat, and includes a base portion to which the light source module is physically coupled. The heat dissipation module also includes a plurality of heat dissipation fins. At least two of the fins that are immediately adjacent to one another form an air channel having a first opening and a second opening between the at least two of the fins. The air channel has a generally decreasing cross-sectional area with respect to air rising up the air channel in a generally vertical direction with respect to a horizontal plane as the air enters the air channel through the first opening and exits the air channel through the second opening.
