Cold Cathode Fluorescent Lamp

Have no filament coils that heat up but cold cathodes.

Cold cathode fluorescent lamp. A cold cathode fluorescent lamp from an emergency exit sign. Have a longer life. Can better handle vibrations. The liquid crystal display lcd has become ubiquitous.

Without direct connection to line voltage current is limited by the transformer alone negating the need for a ballast. Ccfl warehouse is the largest supplier of lcd backlights for lcd repair stocking complete oem ccfl backlight assemblies and ccfl lamps for all types of lcd backlight repair including monitors and laptop ccft lamps led backlights cold cathode lamps for all lcd panel repairs. A cold cathode fluorescent lamp ccfl is a type gas discharge lamp similar to linear fluorescent or compact fluorescent lamps. Advantages ccfl lamp.

Ccfls are used in a number of different specialty applications such as cold weather lighting display back lighting and signage. A cold cathode is a cathode that is not electrically heated by a filament. Product index optoelectronics lamps cold cathode fluorescent ccfl uv lamps cold cathode fluorescent ccfl uv. Advantages eefl lamp.

Cold cathode fluorescent lamps. The lcd utilizes a cold cathode fluorescent lamp as a light source to back light the display. Typically over 1000 v root mean square is required to initiate lamp operation with sustaining voltages ranging from 200 to 800 v ac. 172 14 48000 1.

Operating at a much higher voltage than other fluorescents the lamp produces a low amperage glow discharge rather than an arc similar to a neon light. It is used in gas discharge lamps such as neon lamps discharge tubes and some types of vacuum tube the other type of cathode is a hot cathode which is heated by electric current passing through a filament. Cold cathode fluorescent lamp ccfl and uv lights are light sources that use a mercury vapor to emit uv light that causes a phosphor coating to emit light ccfl and other light sources that provide wavelengths in the ultraviolet frequency range 750 thz to 30 000 thz. The cold cathode lamp is different from a hot cathode in that it has an interior coating that more easily creates free electrons when used with higher voltages.

The ccfl requires a high voltage ac supplies for operation. Ccfl wh lamp 850v 5ma 3x160mm 172 immediate available. A cathode may be considered cold if it emits more electrons than can be supplied by thermionic emission alone. The cold cathode device was not born as a light source.

Smaller thinner and more light weight than a known fluorescent lamp.
