1, neon lights are bright, filled with fine neon or other charged glass tubes or bulbs, and are cold cathode gas discharge lamps. Neon tube is a sealed glass tube with electrodes at both ends, which is filled with some low-pressure gas. A voltage of several thousand volts is applied to the electrode, and the gas in the ionization tube makes it glow.
2. The color of light depends on the gas in the tube. Neon is a transliteration of neon lights. Neon is a rare gas, which emits popular orange light, but using other gases will produce other colors, such as hydrogen (red), helium (yellow), carbon dioxide (white) and mercury vapor (blue).
3. Neon lights rely on the electrode tips at both ends of the lamp to ignite the rare gas in the lamp tube under the action of high voltage electric field. Different from ordinary light source, it must burn tungsten wire to high temperature to emit light, which leads to a lot of electric energy being consumed in the form of heat energy. Therefore, under the same electric energy, the brightness of neon lights is higher.
