Light Emitting Diodes - popularly known as LED's - are devices which are very commonly used in our day to day life, whether we realize it or not. They have been put to use in a wide variety of applications and varied functions. From the tiny lights which blink in equipment to indicate the status, numbers on the digital clocks and messages on the sign boards to television screens which get lighted up by LED's, it has a wide range of requirement and usability. Infrared LED's are used in remote control devices, cameras and similar gadgets.
LED's work on the principle of a semiconductor diode. When electricity is passing through, light of a particular frequency is emitted. Light is made up of a collection of photons propagated as electromagnetic waves. It can be produced by incandescence as well as electroluminescence. The difference between the normal bulb and LED bulb is in how light is produced. A normal bulb, which we call the incandescent bulb, produces light by the heating up of a filament. When the filament is heated up, photons are emitted. In the case of an LED bulb, light is produced by electroluminescence, where photon emission happens when the semiconductor material is electronically excited. Hence they do not require a warm up time to get lighted up, it does not have a filament which will burn out eventually and the loss of energy is reduced.
The emission of light from LED lights is usually in one direction, one half-space of 180°. LED lamps are highly resistant and tolerant to vibrations and heavy shocks. They exhibit longevity and constant use will not result in abrupt failure but only in gradual loss of brightness. This makes them fit for applications like traffic lights where an abrupt failure might prove to be disastrous. Moreover, their small size enables them to be easily accommodated in any kind of electric circuit and is usually used in numbers so that the failure of one LED light will not account to a total failure of the system. They can be easily dimmed and brightened by reducing the power or by switching it on and off in fast cycles. (Please note, there are optics and other options that can be added to create uplight if required)
There are different types of LED's – those which emit visible light by current running through the semiconductor (LED) and those that emit light by using organic compounds as semiconductor material, called OLED. Each type can be used for different types of applications. There are wide ranges of advantages over the conventional methods of lighting, ranging from cost benefits, over lighting quality to high environmental impacts. It is considered that LED's are going to be the future answer for household & industrial lighting.
One of the most popular way to convert over to LED is to retrofit your existing fixture. Retrofitting allows you to take your existing fixture, remove the existing bulb and ballast, and then install the LED Retrofit Kit. Costing up to 50% less than a fixture replacement, retrofitting with LED lets you keep your existing fixtures and eliminates the time and cost of disposing them (and since we are supposed to be thinking of being Green, keeping perfectly good fixtures out of the landfill is a good thing). Secondly, you typically do not need permits or approvals to retrofit, where as you sometimes need them if you are replacing fixtures.
If you really need new fixtures, for example to replace your existing High Bays in your factory or warehouse, then choosing a new LED High Bay is a great option if you choose well. There are times when your fixtures are so old they need to be replaced. There are many options available, and a high bay meant to work well in a warehouse aisle will not necessarily be the best choice in your warehouse space, and vice versa.
