Abstract:
1. A solid-state lighting device comprising: a plurality of light-emitting elements for generating light, including at least one light-emitting element having a first surface area; a heat spreading chassis thermally connected to the plurality of light emitting elements, said heat spreading chassis configured for coupling to at least one heat sink; a mixing chamber optically coupled to the plurality of light-emitting elements for mixing the light emitted by the plurality of light-emitting elements; wherein one or more of the plurality of light-emitting elements are driven by an AC power supply; said one or more of the plurality of light emitting elements emit light substantially perpendicular to an exit aperture of the solid-state lighting device; a control system operatively coupled to the plurality of light-emitting elements for controlling operation of the plurality of light-emitting elements; wherein said one or more of the plurality of light-emitting elements are operatively coupled to a flexible circuit board thermally connected to said heat spreading chassis; said plurality of light-emitting elements further including one or more digitally controlled light-emitting elements configured to modify chromaticity or CCT of said light.
