Neon Sign Transformer - Trout Underground
WebUnless high voltage is used, the electrons will not be attracted strongly enough to start the ionization process. Without ionization, no current will flow and no light will appear. Hence, a high voltage must be used. Transformers are built with secondary voltages that vary from 2000 to 15,000 volts for signs. WebCold Cathode Fluorescent Lamps (CCFLs) are sealed glass tubes filled with inert gases. When a high voltage is placed across the tube, the gases ionize creating ultraviolet (UV) light. The UV light, in turn, excites an inner coating of phosphor, creating visible light. CCFLs have many desirable features, including: Excellent white light source.
