How do neon lamps give colored light?

The cover of the jar light is a neon lamp. You may have seen a board with letters made of crooked, thin colored tube lights. A neon lamp is a type of tubelight useful in advertising and decoration. The tubelight produces white light from the mercury gas but the colored tubelight contains a mixture of neon and argon gases. Neon fluorescent and light emitting deohails convert less electricity into heat than plain electric lamps. So give more light. The neon lamp was invented in the 19th century by a scientist named Georges Claudi. It became popular in 190. A tube filled with neon air gives red light. In the same way different colors of light can be obtained by mixing Christine, Argon and Xenon gases with neon.
