Abstract
A lighting system is described. The lighting system includes a housing, a lighting module, and a cooling system. The lighting module includes a light source and is coupled with the housing. The cooling system includes active cooling cell(s). The lighting module is thermally coupled with the cooling system. The active cooling cell(s) are configured to utilize vibrational motion to drive a fluid for transferring heat from the lighting module. The cooling system is coupled with and contained by the housing.
