Questions with Lamps - Cold Cathode Fluorescent (CCFL) & UV

  • Ask: How do cold cathode fluorescent lamps work?

    Answer: Cold-cathode lamps include cold-cathode fluorescent lamps (CCFLs) and neon lamps. Neon lamps primarily rely on excitation of gas molecules to emit light; CCFLs use a discharge in mercury vapor to develop ultraviolet light, which in turn causes a fluorescent coating on the inside of the lamp to emit visible light.

  • Ask: What is cold cathode lighting?

    Answer: A cold cathode fluorescent lamp (CCFL) is a lighting system that uses two phenomena: electron discharge and fluorescence. CCFLs are mainly used as light sources for backlights, because they are smaller and have longer lifetimes than ordinary fluorescent lamps.

  • Ask: Which coating is used in CCFL?

    Answer: The composition of a CCFL comprises a hollow glass tube made of borosilicate glass with a triphosphor coating lining the internal wall and electrodes for electrical conduction (Kahl, 1998). The triphosphors contain rare earth elements that include yttrium and europium (Rabah, 2008).

  • Ask: What is CCFL LCD?

    Answer: CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the LCD or spaced uniformly over the entire back of the display.
