Abstract:
An LED lamp control system comprises a power supply, a MOS transistor, a signal encoding module, a control signal input module, a signal change judging module, a MOS transistor control module, an LED lamp, a filter capacitor, and a signal decoding module, and a DC/DC converter. The signal encoding module is configured to convert the control signal output by the control signal input module into a PWM signal, and the output of the signal encoding module is connected to the gate of the MOS transistor and output a PWM signal to control the on and off of the MOS transistor, the signal decoding module is configured to convert a PWM signal loaded onto the power supply output which is connected to a MOS transistor to a dimming signal. The DC/DC converter controls the output parameters of the LED lamp according to the dimming signal. The invention makes the connection between the power supply and the LED lamp only use two wires to complete the connection between the lamp and the power supply, thereby helping to reduce the typographical difficulty of the lamp line and also facilitating the control of the structure size of the lamp.
