LED (Light Emitting Diode) is a device that emits light when the electric current is passed through it. As the technology has advanced we today have LED's which can produce lights in many colours. These lights are composed of synthetic material. Older version was not able to produce lights in different colours; it only used to come with green or red colour. These consists of P type semiconductors and N type Semiconductors. Direct connection of these creates a region called P-N Junction.
The photons are released when a diode connects with an electrical current activating the electrons which are present in the diode. The photons which are set free are what we see as light. CFL bulbs emits light as a result of being heated, on the other hand these are more productive and efficient which turns energy into light resulting in minimization of energy radiations as heat. Because of this reason, they are cooler than the CFL bulbs. Advancement and cheaper rates has made it more popular in the fields. It consists of a plastic body which is wrapped into the leads, making the light emit through the plastic bulb. Mostly, these are found in round shape which focuses at one direction only.
LED Lighting Products It has life expectancy up to 11 years with continuous usage or 22 years with half percent usage. Leaving it switched on for 8 hours every day, would take 20 years for you to replace it with the new one bulb. It has different properties than a standard light would have like unlike a standard light, it does not burn out and stop working.
