How does a neon light work?

Answer by  john11 (617)

Neon lights work my exciting valence electrons of noble gasses to their conduction band using a high voltage step-up transformer. These electrons fall down to their valence band after a short time period, releasing a quanta of energy in the visible light spectrum. Different noble cases produce different colored light.

A neon light is a glass tube, usually hand blown and sealed at both ends. Before the sealing of one end, neon gas is used to fill the tube. A transformer is then wired to both ends of the tube to ignite the gas within and keep it burning. Differing mixtures of gas give neon lights their distinctive coloring.

Neon Lights work by an electrical current passing through an electrodes at one end of a gas filled tube. The electricity heats up the neon gas inside which causes the gas to emit a energy in the form a visibal light wave. The type of gas you use determines the color of visibal light.

Mercury/sodium gas is filled in neon light Electrical current passes through the light, electrons will excite photon to emit light. Electrical current exite all atoms which emit photons. Photon energy is directly proportional to colour,and emit same colur light.. Mercury emit pink/red,and sodium emit yellow.
