LAMP PROTECTION SYSTEM AND METHOD

摘要

A video display system such as a liquid crystal display television receiver projection system typically uses a high-intensity discharge lamp of the type that should not be re-started or turned on immediately after being turned off. An improved system protecting the lamp from restarts during a cooling off period. The system maintains the lamp, once energized to produce an image, in an off condition during a predetermined cool-down period following receipt of a power-off. Advantageously, the system automatically powers the lamp on at the end of the cool-down period upon receipt a power-on command during the cool-down period.
