Patent ID: 8427060

Claim:
A high lumen output cold cathode fluorescent lamp (CCFL) device, comprising: at least one CCFL tube containing two electrodes: an anode and a cathode; a supporting structure attached to the cold cathode fluorescent lamp tube; at least one driver having an input and an output; a driver housing containing said at least one driver; and an electrical connector; wherein an input of the driver is connected to a power source through the electrical connector, and the output of the driver is connected to the electrodes of the cold cathode fluorescent lamp tube; wherein said supporting structure, said driver housing, said at least one CCFL tube and said electrical connector are connected to form a unitary lamp with the following characteristics: said at least one CCFL tube having an inside diameter of 3˜16 mm; the length between the anode and cathode being about 200˜1000 times of the inside diameter of the at least one CCFL tube; the electron emission area of the cathode being in a range of about 100˜2,000 mm 2 ; and the ratio of electrode current to the electron emission area of the cathode being in a range of about 0.01˜0.2 mA/mm 2 .
