Abstract: The present invention is a high frequency, high efficiency start and quick restart system including a lamp. It includes hook ups for connecting and applying a power input to circuitry; a switch for switching a lamp on and off, and is connected to control power; auto-ranging voltage control circuitry; and a three stage power factor correction microchip controller. The microchip controller is a Bi-CMOS microchip. There is also a feedback current sensor; a power factor correction regulator; bulb status feedback; a bulb voltage controller; a conditioning filter; a half-bridge; a DC output inverter; and, output and connection for, as well as, a sodium discharge lamp.

Abstract: The present invention is a high frequency, high efficiency start and quick restart system for lighting various types of lamps. It includes electronic circuitry and components mounted on a housing unit. These include hook ups for connecting and applying a power input to the circuitry; a switch for switching a lamp on and off, which switch means is connected to control power; auto-ranging voltage control circuitry; and a three stage power factor correction microchip controller. The microchip controller is a Bi-CMOS microchip and includes a feedback current sensor; a power factor correction regulator; bulb status feedback-means; a bulb voltage controller; a conditioning filter; a half-bridge; a DC output inverter; and, output and connection for a lamp.
