EMISSION THEORY

Cold Cathode Fluorescent Lamp is the fluorescent lamp which is operated in the range
of normal glow discharge. Ar/Ne gas and a small amount of mercury (less than 3mg) are filled in the glass tube coated with phosphor.

By adding high frequency between electrodes at both ends of the glass tube, glow discharge occurs in the low pressure mercury vapor. Mercury atoms which are excited by its discharge, emit ultraviolet rays (Wave Length 254nm ), and these ultraviolet rays excite the phosphor.

When the excited atoms of phosphor return to low energy level, the visible light is emitted.
