Abstract

An electronic lighting system with a driver for providing light from visible light bulbs and non-visible light bulbs, including from infrared, ultraviolet, LED and fluorescent lamps of multiple sizes and wattages, having power factor correction, surge protection, current sensing, current adjustment feedback, and dimming system. There are transformers dedicated to particular lamp receptacles that include interloper diodes and resistor sets that fine tune the functioning of the driver sensing loads. Comparator circuitry receives an external control signal and compares it to feedback from the output side of the circuitry, and thereby controls the Pulse Width Modulation circuitry, which cooperates with feedback-based transistors and a MOSFET gate driver circuit for current limiting to the loads being applied.
