LED lights are miniscule sized bulbs

So what is LED Light really all about? The following report includes some fascinating information about LED Light--info you can use, not just the old stuff they used to tell you.

LED lights are miniscule sized bulbs that are small enough to fit into electrical circuitry. They don't have a filament that is going to burn out, which is where they differ from your standard incandescent light bulb. The other difference is that they don't give off heat. What illuminates LED lights are internal electron movements. The life of LED lights is comparable to the life of transistors.

The basic part of the LED lights, the diode, is a semiconductor in its simplest form. A semiconductor is material that conducts electric current but with variations in strength. A semiconductor is usually composed of a conductor that acts as poorly as it does because of impure atoms of some other material that has become part of it. This addition of these impurities is referred to as doping.

Aluminum gallium arsenide is the most common material for LED conduction. If the material is pure no electrons are free to conduct an electric current. With doping, however, there are more atoms that unbalance the combination, making the material a better conductor.

Once you begin to move beyond basic background information, you begin to realize that there's more to LED Light than you may have first thought.

Solar dock lights collect solar energy during the day. They accomplish this by using small solar panels that are usually positioned on top of the dock light. The energy is then used to recharge a battery located inside the dock light (most of the time the battery is a standard NiCad rechargeable battery). The recharged battery then powers a LED light. These small lights are very bright, but take only a minimal amount of energy to run. Therefore, the energy collected during the daylight hours is enough to power the dock light through many hours at night. Some of the dock lights are able to automatically turn on when the sun goes down, which makes the safety of the lights even greater.

Some solar dock lights even come with the ability to change the color of the LED inside the lamp. This can be very helpful, as you can use different colors such as red and green to mark the left and right of your dock. You can also buy several of the dock lights in order to line a path down your dock in bright white light. These dock lights are also made to fit all standard docks and posts, so you can be sure that they will fit on your own dock.

It never hurts to be well-informed with the latest on LED Light. Compare what you've learned here to future articles so that you can stay alert to changes in the area of LED Light.
