WebHow Luminous Lamps Work Fundamentally, the luminous tube is a very simple device. It consists of an evacuated glass tube fitted at each end with a metal terminal called an electrode. Inside the tube is a small amount of highly purified inert gas. Connected to the two electrodes is a source of high-voltage electrical power. When Web1,406 products. High voltage signs bring attention to voltage hazards that may not always be visible or obvious. These informative notices are posted near high voltage equipment and machinery to discourage unauthorized entry to the area and help prevent electrocution injuries or death. Danger: High Voltage Signs.

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.
