Imagine Life without Light? Actually, we cannot even imagine life without light .Light became an important factor of human's living for doing activities smoothly and safer. LED (Light Emitting Diode) brought another revolution into the world of light. LED light gave people to be molt light in different modes, with a greater degree of safety. The development of LED lighting had give historical contribution to the green atmosphere because there is no use of wire, tungsten and no release of gas. LED lighting is a revolutionary leap in lighting technology.
LED lighting not only gave us light, but also providing its additional features of power saving , many applications easy to use ,low costing .In contrast with other source LED is a mercury-free light source ,its is highly flexible can be given desired shape, having a non-electromagnetic interference and no harmful rays. Despite this LED is also having many other factor, which makes it different with other source - no high-pressure part, much less to the cost of insulation, high reliability; accessories simple - no starter, structure is simple, not inflated, no glass case, no gas sealing problems, impact resistance; controllable - fast response time can be repeated frequently light on-off., lightweight structures - and materials, cost savings; of low light intensity and stiffness.
The size of one LED is very small, can be in centimeter we can have an example of LED, we see in our daily life in traffic signal, computer mouse etc.
The most important factor, which makes LED so popular is its safety factor it can not give you shock like other lighting source and it is resistive in nature. Compact LED lamps can be example large cells from the LED it is a collection of large number of LED's and can acquire any shape. LED light gives you smoothie light without any side effect.
