To solve the problem of poor stable output performance of LED lighting driving circuits,this paper takes the design of LED lighting driving circuits based on constant current diodes as an example,and conducts a study on the working principle,stability analysis,and efficiency calculation of the circuit.A solution using constant current diodes to achieve constant current driving of LED is proposed.Theoretical calculations and experimental tests prove that the designed driving circuit can provide stable driving current for LED,to ensure stable luminescence and high conversion efficiency,in order to provide reference for LED lighting engineering technicians.
