Driving device for light-emitting diode
2006
A light-emitting diode driving apparatus, driving apparatus using the integration circuit of the operational amplifier, a current flowing through the LED control Ping Heng and suppresses the inrush current. The driving device comprising: a variable resistor, which is received by the desired driving the light emitting diode in series a DC voltage source; a resistor connected to one end of the variable resistor, the other end is connected to a fixed voltage; and an integrating circuit , connected to a node between the resistor and the variable resistor and the variable resistor.
