| Abstract: | The paper proposes switching constant flow drive circuit based on the characteristics of LED.By using electric current and a voltage's negative feedback technology,the author controls LED's incoming current under a steady electric current value,and also prevents the circuit from improving its capacity through the voltage so as to increase its reliability. |
