Working Principle of Purple Excitation Lamp

The working principle of a purple excitation lamp is based on the emission of ultraviolet light. When the lamp is powered on, the electrical energy is converted into heat and light. The heat causes the electrons in the gas-filled tube to gain energy and move to higher energy levels. When these electrons return to their original energy levels, they emit ultraviolet light with a wavelength of around 405 nanometers. The emitted ultraviolet light is then converted into visible light by a phosphor coating on the inner surface of the lamp. This process is known as phosphorescence. The resulting purple light is used to excite fluorescent substances and generate useful information.
