SYSTEM AND METHOD FOR APPLYING POWER TO HIGH INTENSITY DISCHARGE LAMPS

摘要

A liquid crystal display television receiver projection system (100) uses a controller (131) responsive to a first signal by providing power to a first set of circuits of the system(100). The controller (131) is responsive to a second signal by removing power from a second set of circuits of the system (100); A timer (135) defines a time interval between an instance of a power off signal and an instance of a power on signal. In the event a user issues a power on command before the first interval has elapsed, power will be applied to circuits other than the lamp 107. The lamp 107 will remain de- energized until the first interval has elapsed. Therefore, a user is prevented from re-striking the lamp 107. ® KIPO & WIPO 2007
