Abstract
The disclosed subject matter includes a fluorescent lamp and particularly a cold cathode fluorescent lamp that can be employed as a light source for a LCD backlight unit for a television, a computer, a display, and the like. The fluorescent lamp can include a couple of electrode units located opposite to each other at each end of a tube, a couple of welding beads sealing both the tube and the couple of electrode units, and a filler gas located in the tube. Each of the electrode units can include an emitter electrode that is configured with a crystalline silicon semiconductor material having an electrical conductivity or configured with other semiconductor materials, and can include a concave portion formed thereon. The electrode units can prevent blackening on an inner surface of the tube by avoiding the occurrence of spattering. Thus, the fluorescent lamp using the electrode units can enjoy a long life, high reliability, easy manufacture, and the like.
