Fluorescent vs. Neon Lights sign

January 20th, 2011 Posted in Uncategorized

A fluorescent light is the type of light most commonly used in all commercial buildings, shopping centers and residences to create white. The fluorescent lights have utility value as they serve to dispel darkness during nights. These are usually straight tubes and available in lengths of 2 feet and 4 feet and in diameters of 1 or 1 1/2 inch. Fluorescent lights have a much wider range of applications and cost less. The neon lights sign are costlier and are primarily used for decoration and publicity purposes.

The technology behind neon lights sign is nothing complicated. The glass tube is filled with a gas like neon, argon or krypton at low pressure. Metal electrodes are placed at both ends of the tube. When a high voltage is applied to the electrodes, the neon gas naturally ionizes and the electrons flow through the gas. These electrons activate the neon atoms and trigger them to emit light. Neon emits red light while the other gases emit different colors. Argon, xenon, krypton and other types of gases are used in varying quantities to produce different colors. As a result, neon lights radiate bright reds, blue, green and other eye-catchy colors.

The technology used for fluorescent lights are similar to neon lights but inside a fluorescent light, a low-pressure mercury vapor is introduced. It more uses a combination of argon and a small amount of mercury to create energy. When ionized, the mercury vapor inside emits ultraviolet light.
