Light source driving circuit with dimming control function |
摘要 |
A dimming control device is disclosed for controlling a switch of a voltage boosting circuit to output voltage or not so as to control the lumen of the set of LEDs utilizing the voltage boosting circuit. The dimming control device includes a switch. The switch of the dimming control device receives a dimming signal and accordingly controls "ON" or "OFF" states of the switch of the voltage boosting circuit. In this way, the period of a predetermined current flowing through the set of the LEDs can be adjusted and the lumen of the set of the LEDs is adjusted.
