10/17/2023 0 Comments Cold cathode lights![]() ![]() Most systems that have LCD panels run on direct current (DC), the DC has to be converted to AC in order to power the lamp. Typically, the resulting temperature color is in the 2800 - 3200K range, which looks like a warm to standard white light. The phosphorus make-up determines the color temperature of the visible light output. The ultraviolet energy excites the phosphorescent lining which then produces light in the visible range (400 to 700 nm). When the high voltage is applied the resulting arc ionizes the internal noble gas which produces ultraviolet energy. The tube is then sealed at both ends with an iron-nickel electrode located at each end of the tube.ĬCFLs operate on high-voltage alternating current (AC). These backlights usually have a hollow glass cylinder - 2 to 10 mm in diameter, that’s internally coated with a phosphorescent material and filled with a noble gas (most commonly argon). This includes the full spectrum of white lamps commonly used in various LCD screens as well as specialty color, UV, and infrared lamps that are used in a wide range of applications.ĬCFLs have been used for years as a backlight source. We also specialize in precision color-matching technology and use the latest in testing equipment that allows us to both analyze and produce any color CCFL backlight you want.
