A driving device is provided for a cathode fluorescent lamp (CCFL) circuit, comprising a voltage generator outputting a driving voltage and a controller coupled thereto. The controller directs the voltage generator to output a first voltage exceeding a working voltage of the CCFL to initialize the CCFL. When brightness of the cold cathode lamp tube exceeds a working brightness of the CCFL, the controller directs the voltage generator to decrease the driving voltage gradually so that the brightness of the CCFL equals the working brightness. The controller stops decreasing the driving voltage when the driving voltage equals the working voltage.

Method and apparatus for a CCFL driving device

The subject matter relates to a computer peripheral power distribution device, comprising a PC, a keyboard and a scanner, wherein one of the USB ports of the PC is connected by a USB wire to the USB control and microprocessor of the scanner; the keyboard is connected by a transmission cable respectively to the PC and the motor control and step motor of the scanner, thus by such connection, the working power for said scanner may come from the power transmitted from the PC through the USB port and the keyboard, so that it will not only eliminate the installation of a DC converter within the scanner, but will also reduce its total weight, and achieve the purposes of reduced power consumption, convenient portability and reduced costs.
