Auto-control LED lamp

The invention relates to an auto-control LED lamp comprising a housing, an LED lamp and a drive circuit. The auto-control LED lamp is characterized in that an alternating current to direct current circuit A is connected with a high-low level conversion circuit D and a switch K, an alternating current to direct current circuit B is connected with an LED lamp on circuit F and the switch K, and the high-low level conversion circuit D is connected with an optical control circuit C and a relay control circuit E. The auto-control LED lamp has the advantages that the design is scientific and reasonable, the drive circuit has few devices and high reliability, and the cost is low.
