Patents by Inventor Chin-Chuang Chueh

Chin-Chuang Chueh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8704457
    Abstract: A power conversion circuit for light emitting diode includes a voltage converter. The voltage converter has two receiving terminals and two output terminals. The two receiving terminals of the voltage converter are electrically coupled to the direct current power supply, and the output terminals output corresponding direct current signals according to the received direct current power supply, to drive a light emitting diode string. One of the output terminals has a positive potential, and another output terminal has a negative potential.

  • Patent number: 8390210
    Abstract: A light driver circuit device for synchronously driving a plurality of cold cathode fluorescent lamps (CCFLs) is provided. The light driver circuit device includes an inverter circuit board and a balance circuit board. The inverter circuit board has an inverter circuit coupled to a driving signal for outputting a driving voltage to drive the CCFLs synchronously. The balance circuit board and the inverter circuit board are installed separately, and the balance circuit board has a balance circuit coupled to a terminal of each CCFL and the inverter circuit. The CCFL driving architecture is designed to install the inverter circuit and the balance circuit individually, thus effectively reducing the space of the driving circuit and the total cost of the circuit design. Furthermore, the balance circuit board can balance the current in each CCFL effectively, and there is no limitation to where the balance circuit board can be disposed.
