Abstract: Aiming at solving the problems of low power factor and dissactisfactory dimming effect,the principles of SCR dimming in CED driver system is explained.Accordingly,SCR dimming in LED system with 50 W power is designed based on SSL 2103.That system consists of main circuit and feedback circuit.Simulation experiment showed that that system can function properly and meet the designing goal.

Key words: SSL2103, LED driver, SCR dimming, flyback topologies
