Are widely used many areas where low current and high intensity are needed. Cold Cathode Fluorescent Lamp (CCFL) is the fluorescent lamp which is operated in the range of normal glow discharge ,Rare gas and a slight amount of mercury (a few mg ) are filled in the glass tube coated with phosphor .By adding high electric field between electrodes at both ends of the glass tube, glow discharge occurs in the lower pressure mercury vapor. Mercury atoms which are excited by its discharge, emit ultraviolet rays. (253.7um),and these ultraviolet rays excite the phosphor rig. Features: 1) High brightness ; 2) High efficiency ; 3) Low power consumption ; 4) Excellent vibration and impact resistance ; 5) Quick start at lower temperature ; 6) Small size ; 7) Lower heating ; 8) Longer life ; 9) Applications: a) LCD backlight, scanner and copy machine ; b) Varies types ; c) Advertising boxes and decoration lighting ; d) Other assistant illumination
