LED’s are largely used as signal lamps in many appliances and more and more people are increasing using LED lighting. LED means light emitting diode which belongs to semiconductor category. It originated in 1960 when it was used for producing low intensity lighting, but nowadays it is primarily used for ultraviolet lighting delivering powerful brightness and energy.
The mechanism or the functioning of LED lights is really simple to understand. Whenever you switch on the light emitting diode light series of electrons combine together with lots of electronic holes inside the appliance, thereby releasing energy. The resulting effect is called as electro-luminescence and it gives various colors depending on the semiconductor and its energy. Normally LED is very small and it occupies only 1mm of surface, however you can use many optical elements for designing its radiation. When compared with other traditional light sources LED lights are highly advantageous since it consumes very less energy. Though it is smaller in size, you cannot tell that it cannot work efficiently. It can work non-stop for long hours and is highly strong and robust in its efficiency.
Even a small light of LED can create brightness to the entire room. But it you compare the power of fluorescent lamps with LED you can understand its quality and efficiency. Light emitting diodes lamps are widely used in aviation industry and in automotive industry. Have you ever watched the brake lamps in your car and powerful turn indicators which emits flash of colored lights? They are nothing but LED lights. That apart you can also find these lights in traffic signals which are clearly visible even in misty weather conditions. Of late infrared LED lights find application in remote control devices which is used for operating television, DVD sets and recorders and many other domestic appliances.
The lights of LED are very small in size but big in capacity and functions. Owing to is efficiency and power saving nature many people use these lights in their home. Apart from domestic usage, it is also used in industries and organizations and any other business enterprise. You can also these lights as decorative lights and have brilliant effect in your garden. When it comes to party you can use several colors of LED lights to illuminate the event. In case you have not used LED lighting so far, it is time for you to switchover to these lights which are power saving and reliable for you. Since the light originates from solid object unlike other lights which come from gases these lights do not heat the surrounding even it burns for long duration.
