Cold cathode fluorescent Lamp ( CCFL) belongs to gas discharge lamp. CCFL is a light source classified as an electronic component. In the electric field, radiant energy makes phosphor lighting.

Inside the phosphor coated glass tube, there are rare gases and a slight amount of mercury. By the reason of high electric field between two ends, a few electrons will hit electrodes. Then more and more electrons come out, as a result of this, gas discharge occurs. Mercury atoms will emit 253.7 nm ultraviolet rays.

Features (CCFL)
High brightness, High-Efficiency, Low power consumption and long life.
Excellent vibration and impact resistance.
Durable and excellent blinking characteristics.
Quick start at low temperature.
Small size and light weight.
Low heating.

Applications (CCFL)
Backlighting for LCD.
Light sources for Scanner.
Various types of displays and decorating lights
