Abstract
The present invention is a high ORequency, 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 metal-halide discharge lamp.
Claims18
A high frequency, high efficiency electronic 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;
- (v) a feedback current sensor;
- (vi) a power factor correction regulator;
- (vii) lamp status feedback means;
- (viii) a lamp voltage controller;
- (ix) a conditioning filter;
- (x) a half-bridge;
- (xi) a DC output inverter;
- and,
- (xii) output means and connection for a lamp;
- and,
- (c) a metal-halide discharge lamp which is includes a discharge vessel having a cavity, two electrodes operatively positioned within said cavity, and an ionizable filling within said cavity, said filling comprising at least one inert gas, mercury, at least one halogen and at least one metal capable of chemically combining and dissociating with the halogen.
