  • Patent number: 8183781
    Abstract: A fluorescent lamp includes at least two lighting elements, which emit lights with different color temperatures. In addition, the lighting illuminations of the lighting elements can be controlled by independent driving devices. Thus, the user can adjust the color temperature of the light emitted from the fluorescent lamp.

  • Patent number: 7250716
    Abstract: A cold cathode flat fluorescent lamp (CCFFL) comprising a flat lamp chamber, fluorescent substance, discharge gas, and a patterned electrode is provided. The discharge gas is disposed in the gas discharge chamber. The fluorescent substance is disposed over the inner wall of the gas discharge chamber. The patterned electrode is disposed over a surface of the flat lamp chamber. In an embodiment, the patterned electrode comprises anode pairs and cathode pairs which are alternately arranged. Each anode pair comprises a first meandering anode with first protrusions and a second meandering anode with second protrusions, wherein the first protrusions and the second protrusions are staggered. Each cathode pair comprises a first meandering cathode with third protrusions and a second meandering cathode with fourth protrusions, wherein each third protrusion aligns with each second protrusion, and each fourth protrusion aligns with each first protrusion.

  • Patent number: 7218064
    Abstract: A cold cathode flat fluorescent lamp and a driving method for a cold cathode flat fluorescent lamp are provided. The cold cathode flat fluorescent lamp includes a lamp, a transformer and a full-bridge circuit. The lamp has at least a first electrode having a first voltage and a second electrode having a second voltage. The transformer has a primary side and a secondary side, and the full-bridge circuit is used for driving the lamp. In addition, the transformer is connected to the lamp on the secondary side and is connected to the full-bridge circuit on the primary side.

  • Publication number: 20060226791
    Abstract: The present invention relates to a method adopting square voltage waveform for driving a flat lamp used as the light source of a flat panel display or a common light fixture, the method comprising steps of: using a power unit to convert direct current into voltage of square waveform; using a voltage booster to raise the crest of the square voltage waveform to a specific trigger voltage capable of turning on the flat lamp; and providing a pulse-type current while enabling the pulse-type current to be just larger enough to break the dielectric barrier of the flat lamp.

  • Publication number: 20060114373
    Abstract: A planar light source including a transflective film, a plurality of cold cathode fluorescence flat lamps and at least one reflective component to provide a uniform light source is described. A portion of the light emitted from the emitting areas of the cold cathode fluorescence flat lamps passes through the transflective film, and the other portion of the light is reflected to the reflective component by the transflective film. Then, the light is reflected to the dark areas between the emitting areas to compensate the brightness of the dark areas. When the brightness of the dark areas is compensated, the planar light source provides a uniform light without dark stripes.
