  • CCFL wrapped with a heater wire, and machines for manufacturing same
    Patent number: 6928707
    Abstract: One aspect of the invention is embodied in a machine for wrapping a heater wire around a cold cathode fluorescent lamp (CCFL). The machine includes means for holding a CCFL, means for guiding a heater wire, and means for moving the holding means in relation to the guiding means for the purpose of wrapping a heater wire around a CCFL that is held by the holding means. Another aspect of the invention is embodied in a CCFL wrapped with a heater wire. The process used to wrap the CCFL involves inserting the CCFL into a socket of an automated machine and feeding the heater wire into a heater wire guide of the automated machine.
