Abstract (en)

[origin: EP0653903A2] A cold cathode fluorescent tube assembly comprises a cold cathode fluorescent tube (1) having first and second terminals (2,3) and a voltage source (7) connected to the terminals to generate a voltage therebetween. The first terminal extends (4) along the tube and is arranged such that progressively varying the voltage applied to the terminals by the voltage source causes fluorescence to occur in a corresponding progressive manner along the tube. <IMAGE>
