Abstract:
A high frequency, high efficiency quick restart system for lighting, which comprises:(a) a housing unit to mount electronic circuitry and related components; (b) electronic circuitry and components mounted on said housing unit, which includes: (i) means for connecting and applying a power input to said circuitry; (ii) switch means for switching a lamp on and off, which switch means is connected to control power to said circuitry; (iii) auto-ranging voltage control circuitry and components, including an auto line supply filter and a line voltage correction EMI to provide an auto-ranging voltage intake/output capability; (iv) a three stage power factor correction microchip controller, said microchip controller being a Bi-CMOS microchip having a low range start-up current of less than about 0.55 milliamps; (v) a feedback current sensor; (vi) a power factor correction regulator; (vii) bulb status feedback means; (viii) a bulb voltage controller; (ix) a conditioning filter; (x) a half-bridge; (xi) a DC output inverter; and, (xii) output means and connection for a lamp.
