LOW TEMPERATURE COMPENSATION LAMP HEATING APPARATUS OOF REFRIGERATOR

摘要

A control unit outputs control signal for driving lamp and for low temperature compensation, based on door open/close and external temperature signals. The relay and switch connected in series with lamp unit, are tuned ON/OFF based on control signal. A diode connected in series with relay, lowers the voltage applied to lamp, by half-wave rectification. An independent claim is also included for control method of heat generator.
