Light tube type neon lights filled with neon gas, the neon light emits red light, filled with argon can make it emit light blue light, filled with helium can make it emit reddish light, mercury vapor can make it emit purple light; fluorescent neon lights are filled Argon and mercury, neon lights emit blue, yellow and other light. Both types of neon lights rely on the stimulated radiation of the working gas atoms in the tube to emit light. Sometimes people mix them together and put them in neon lights to make them emit colorful lights. Helium: pink Neon gas: red, used for aviation and navigation as indicator light Argon gas: purple blue Krypton gas: full of krypton gas, which can increase the luminous flux output by 10% Xenon: strong light, used for lighting in large public places (squares, stadiums, airports, etc.) The principle of neon light is in a closed glass tube filled with neon, helium, argon and other gases. Two metal electrodes are installed a...
