Controller for gas discharge lamps

摘要: controller for a gas discharge lamp 18 supplies the with direct current which has been pulse-width modulated at high frequency switch 24, smoothed and passed through polarity inversion circuit 14. The periodically reverses of supplied to equalize electrode wear in 18. senses voltage, current, power or other characteristics maintains least one operating parameter lamp, example constant. A warm up cycle allows this be adjusted fast starting lamp.
