Neon sign.
A neon lamp is a gas-discharge lamp, which is a hollow tube filled with neon or another inert gas under low pressure. Gas by passing an electric current emits a bright glow. The color of the glow of a neon lamp depends not only on the composition of the gas mixture, but also on the current density, as well as on its frequency. When the current density is low, the lamp shines orange and as it increases, the spectrum shifts to the red. By increasing the current frequency to a few MHz, the discharge in the lamp, on the contrary, turns blue. A tube filled with neon gives yellow, orange, red light, and in combination with other inert gases gives a very different color — from blue and purple to green, and more than 300 color shades can be achieved.
