SOLID-STATE LIGHTING DEVICE Russian patent published in 2013 - IPC F21V29/00 

FIELD: physics.

SUBSTANCE: solid-state lighting device (500) includes a plurality of light-emitting elements (510, 525, 530) configured to generate light, which are thermally connected to a heat-dissipating chassis configured for connection to one or more heat sinks (520). The lighting device further includes a mixing chamber which is optically connected to the plurality of light-emitting elements and configured to mix light emitted by the plurality of light-emitting elements. One or more of the plurality of light-emitting elements emit light substantially perpendicular to the exit aperture of the solid-state lighting device. A control system is operatively connected to the plurality of light-emitting elements and is configured to control operation of the plurality of light-emitting elements. One or more of the plurality of light-emitting elements are operatively connected to a flexible circuit board which is thermally connected to the heat-dissipating chassis. The plurality of light-emitting elements further includes one or more digitally controlled light- emitting elements configured to modify chromaticity of the correlated colour temperature (CCT) of the light.

EFFECT: improved full dissipation of heat coupled with a modular design of the electric device.
