Abstract

A synchronous start-up circuit with a constant current deep dimmable power supply; when the output voltage of the current source does not reach the start voltage of an LED luminaire, the circuit is disconnected; when the output voltage reaches the start voltage of the LED luminaire, an enabling switch circuit turns on and outputs a power-off signal, which is used for controlling the current source to wait for the output voltage of other constant current sources to reach the start voltage of the corresponding LED luminaire. When the output voltage of the constant current source reaches the starting voltage of the corresponding LED luminaire, each starting switch circuit receives a synchronized starting signal, each starting switch circuit is turned on, and each current source discharges to supply power for the LED luminaire.
