You would think that all signs designed and built for the purpose of attracting business are the same; however, there are many different types of commercial signs.

Much sign terminology is based on where the sign is physically located on the business establishment. A very common location sign is a window sign, which is a sign that is placed directed onto, behind, or within the direct vicinity of the store window. There is the canopy sign which is a sign above any type of protective awning or cover located over entrances or exits of businesses. There is the roof sign, which obviously is a sign placed onto the roof of an establishment or any of the servicing buildings of the establishment. There is the wall sign, which can be commercially printed or painted. A projecting sign is a sign that extends from a building and is typically targeted at passer-by foot traffic. The billboard is a raised, off-site sign, typically roadside and much larger than other types of signs. People also advertise on mobile vehicular signs.

There are also different forms of advertising signs. A neon sign is a bright glowing gas-filled tubular-glass sign, very effective at drawing attention. An animated sign can be a neon, LED, or LCD sign that uses action and special effects similar to video and motion pictures. It is important as a business owner to make sure which advertising signs are appropriate and effective for your business and which are permitted in your location.

Ever wondered about the difference between neon lights and florescent lights? It is common mistake among people to confuse between the neon signs and florescent lights. Basically the neon light is the sort of light that has been widely used in advertising signs. They are made of long narrow glass tubes and these tubes are very flexible. They can be bent to form all sorts of shapes. Thus the tube of a neon light is used to spell out words like the names of shops and products. The neon sign emit lights in different colors. On the other hand, a fluorescent light is often a long straight tube that produces white light. They are widely used in offices, stores and even at homes.

The neon light may look like a wonder but the working principle is relatively simple. There would be a gas like neon, argon or krypton at low pressure inside the glass tube. There would be metal electrodes at both end of the tube. The neon gas inside the tube ionizes as you apply a high voltage to the electrodes. The electrons excite the neon atoms and as a result light is been emitted that is visible to us.

Now the idea behind the working of fluorescent lights is almost the same but with an extra step in it. There is a low pressure mercury vapor inside the fluorescent lamps. This mercury vapor would emit ultra violet light when it is ionized. The ultra violet rays are not visible for human eyes. Hence the inside of the lamp is coated with a phosphor which is capable of accepting energy in any form and emitting it in the form of visible light. Thus in a fluorescent light, the phosphor accepts energy and emits visible photons.
