ABSTRACT:
A rapid warmup light actuator is disclosed to solve the problems that the light actuator cannot rapidly warm up the lighting load in the prior art and that unstable light sources result from the rapid temperature drop if the light is instantaneously disconnected and restarted. The device consists of an energy storage circuit, an oscillatory circuit, and a transformer. In the beginning of power supply, the energy storage circuit is charged. When starting the lighting load, the energy stored in the energy storage circuit rapidly warms up the lighting load in order to illuminate stable light. Using the energy stored in the energy storage circuit, the lighting load can continue its stable status even it is instantaneously disconnected and restarted.
