LED CURRENT CONTROL CIRCUIT

摘要

The present invention discloses an LED current control circuit. The LED current control circuit does not include an output capacitor and has an LED and an inductor connected in series. Accordingly, the LED current control circuit can adjust the brightness of the LED by controlling the current of the inductor. According to the present invention, the LED current control circuit includes: an LED; an inductor connected to the LED in series; and a current controller which controls the current flowing through the inductor. By not employing a capacitor connected to the LED in parallel, the LED current control circuit controls the current flowing through the inductor to adjust the brightness of the LED.
