Abstract: First and second LED channels of different color temperatures are connected to respective first and second FET drivers. A wall dimmer output is connected to a driver circuit and to circuitry which generates a variable DC voltage. A microcontroller is configured to employ a signal derived from the driver circuit output to generate changing PWM signals which are supplied along with the variable DC voltage to each of the first and second FET drivers to create variable mixed light color and brightness.

Abstract: A compact LED light fixture includes an LED circuit board whose top surface mounts one or more LED's and an A.C. LED Driver circuit. An input circuit board is mounted on an underside of the mounting platform. Unconditioned A.C. power from electrical cables positioned in a wire way is conducted by an electrical connector to the top surface the LED circuit board, then across and down through the top surface of the LED circuit board to the input circuit board where the A.C. power is conditioned and then conducted back through the LED circuit board to the A.C. LED driver.

Abstract: A plurality of LED light fixtures are mounted in a ceiling of an auditorium and a power control system is positioned in an area separate from a seating area of the auditorium for supplying power to the LED light fixtures. Each LED light fixture comprises an extrusion carrying one or more ambience light LED modules for providing ambient light and one or more high intensity LED modules for providing full level lighting. The power control system is configured to collectively switch the ambience light LED modules “on” and “off” and to separately and collectively switch the high intensity LED modules “on” and “off” to thereby provide either low level ambient light or high intensity full level lighting to the auditorium.

Abstract: First and second modules carrying LED circuit boards are interconnected by an interconnection mechanism which enables the modules to both pivot and move linearly with respect to one another such that the distance and angle between the modules may each be varied.
