Title: LIGHT EMITTING DIODE (LED) LIGHTING SYSTEMS AND METHODS
Abstract:
Methods, systems, and devices for light emitting diode (LED) lighting, including at least one of a multi-channel LED driver circuit including an electromagnetic interference (EMI) filter and rectification circuit, a power factor correction (PFC) circuit, a current and voltage isolation circuit, a voltage control circuit, and a current control circuit; a printed circuit board (PCB) including one or more surface mount or screw mount LEDs and electrically coupled to the LED driver circuit; a heat sink including an intercooling and ventilation chamber for air or water cooling disposed therein and thermally coupled to the PCB; and a lens housing having one or more lenses integrally formed therein and removably coupled to the heat sink with the lenses disposed over the LEDs.
