Low power consuming Led panels

Led stand for the light emitting diodes and these diodes consumes a very less amount of power and these are also very long life due to the very less heating capacity. Normally a led light  produces a less amount of light as we can’t use a single led for lighting the sources so we use it as a panel so that it can produce a huge amount of light and the size of the panels depends the capacity of its light emitting. Led light first of all mainly used in the indicators and the signals in electronic products and laboratory uses. But now these days power consumption is so high that power consuming rate is higher than that of power production rate, So to maintain the power ration and fulfil the power needs alternate power sources are used for saving the power.Many countries uses direct power supply  for saving the power and making power appliances long lives, In  DC  power  systems light continuously flows in two different wires mainly known as positive and neutral wires so power appliances work for a long time without any failure, but in the case of alternate power supply only single wire contains both positive and neutrals charge frequently and this frequency is so high that we can’t see it but in AC power supply appliances are not work  properly for a long time.

Led panels are mainly electrons which move from the negative terminal to the positive terminal   in an electron gun which continuously ejects electrons from the cathode towards the anode terminal of the gun and inside the gun a np type semiconductor forms between the cathode and anode terminals of the electron gun. In led light electrons are travels from cathode to anode with a very high velocity and these moving electrons accelerated by the incoming  power supply and in this way they emit light. Led light production is based on the  phenomenon of the Electrominescence which states that a light is produced when a radioactive material is passed with a high speed from a strong electric field. This phenomenon is used by the led lights and  when these small led a simultaneously combined than it produces large amount of light and these sources of light is known as the led panels. Now these days led lights are also used in the decoration and other parties in various colours which makes more interesting.Due to its low power consumption led are used in street lights and battery operated sources of the lights.
