ENERGY-CONSERVING DEVICE OF ILLUMINATION SYSTEM

摘要

The invention discloses an energy-conserving device for illumination system. The energy-conserving device is connected between a power supply of and a lighting assembly of the illumination system. The energy-conserving assembly includes a first switch; an additional ballast; and an additional compensating capacitor. The additional ballast is connected between the power supply and the lighting assembly, and connected between the first terminal and the second terminal of the first switch. The additional compensating capacitor is connected between the power supply and the third terminal of the switch. The energy-conserving device may further include a resistor and a second switch which are connected in parallel with the additional ballast. The energy-conserving device can achieve light regulation and energy-conserving without changing the conventional illumination system and has advantages of good effect of energy-conserving, low cost and long lifetime.
