Abstract:
A fluorescent lamp with a multiple electrodes at each input, where 3 to 8 electrodes may be installed in a single electrode holder sealed at each end of the fluorescent lamp tube. In operation, electron discharge primarily only occurs from one electrode at each input end, which has smallest resistance. With multiple electrodes, the electron discharge function at each input end will last one to several times longer, compared with the input end with just a single electrode. Because the life span of the fluorescent lamp depends on the electron discharge function at each input end, multiple electrodes at each input end increases the overall service life of the lamp. This invention increases cost-effectiveness of the fluorescent lamp without requiring complex structural modifications.

The present invention discloses an improved electrode structure of planar lamp, which applies to the planar lamp that has a gas-discharge cavity with at least a bending channel and with a discharge gas and a fluorescent material equipped thereinside. Via disposing an electrically conductive element, which traverses the bending channels, onto the discharge electrodes on the external wall of the gas-discharge cavity, the input area of the power output by the discharge electrodes is increased, and thus, the light uniformity of the planar lamp is achieved.
