Neon Lamp is a type of discharge lamp filled with neon gas or other inert gases, primarily used for indicators, decoration, or lighting. Neon is a rare gas with a highly stable chemical nature, and when discharged, it emits a bright and vibrant red light, which is the most well-known feature of neon lamps. However, by altering the filling gas or adding fluorescent substances, neon lamps can also emit other colors of light, such as blue, green, yellow, etc.
The working principle of a neon lamp is based on the phenomenon of gas discharge. When sufficient voltage is applied to both ends of the neon lamp, electrons in the neon gas are accelerated and gain enough energy to collide with gas atoms, causing the atoms to ionize and release more electrons. These electrons and ions continuously collide and recombine under the influence of the electric field, releasing light energy, which forms the visible light we see.
Neon lamps have many advantages, such as high luminous efficiency, long service life (up to tens of thousands of hours), resistance to vibration and shock, and a wide operating voltage range. Therefore, they are widely used in various fields, such as advertising signs, indicator lights, signal lights, and displays for electronic instruments. In addition, due to their unique visual effects, neon lamps are often used for decoration and atmosphere creation, such as neon signboards made from neon and other inert gas discharge lamps.
It is worth noting that although neon lamps are safe under normal use, their operating voltage is typically high (ranging from several thousand to tens of thousands of volts), so special attention must be paid to safety during use and installation. Moreover, since neon lamps are gas discharge light sources, their luminous efficiency is relatively low, and the color range is limited, making them less suitable for situations requiring high-efficiency, multi-color lighting.
