Abstract
A lamp control system includes a first driving circuit, an assistance DC power source having an output voltage lower than a working voltage of a lamp and a second driving circuit. The first driving circuit electrically connects the lamp with a utility power source to convert an AC power a DC power and supply the DC power to the lamp. The second driving circuit electrically connects the assistance DC power source with the lamp. The second driving circuit includes a boost circuit, which is connected to the assistance DC power source to promote the output voltage of the assistance DC power source to the working voltage of the lamp and then supply electrical power with the promoted voltage to the lamp when the utility power source is off.
