<p>The present disclosure provides a variable energy lamp control circuit, including a power supply management circuit, an alternating current detection and high-frequency signal transmission circuit, a manual switch, a high-frequency signal receiving circuit, a delay circuit working power input control circuit, a work delay circuit, an alternating current sensing circuit, a control signal conversion circuit, and a driving circuit. The control signal conversion circuit is configured for controlling on and off of the variable energy lamp via the driving circuit according to a first control signal outputted from a first control signal output terminal of the alternating current detection and high-frequency signal transmission circuit, a second control signal outputted from an output terminal of the alternating current sensing circuit, and a third control signal outputted form a third control signal output terminal of the work delay circuit. The present disclosure allows the variable energy lamp to be applicable in ordinary lighting and emergency lighting and to be used as an early-warning light; in addition, the present disclosure is capable of controlling on and off of the variable energy lamp via a manual switch.</p> |
