It is a lamp that uses LEDs (light-emitting diodes) as the source of light. The movement of electrons through a semiconductor material causes tiny light sources to become illuminated. That effect is known as electroluminescence. LED lights belong to a family of lighting technologies called Solid-State lighting.
The LED as a phenomenon was discovered in 1907 by the British experimenter Henry Joseph. He discovered that silicon carbide crystals could produce light when subjected to electric currents. Russian Oleg Vladimirovich Losev reported creation of the first LED in 1927. Rubin Braunstein from the Radio Corporation of America, together with Robert Biard and Gary Pittman of Texas Instruments, reported creation of the first infrared LED in 1962.
The first practical visible-spectrum (red) LED light was developed in 1962 by a General Electric’s scientist, Nick Holonyak, and he is seen as the "father of the light-emitting diode”.
In 2002, light output from LED lights was about 20 lumens per watt. A decade later, commercial and industrial LED lights routinely produce 80-120 Lumens per watt.
Some experimental LEDs have been reported to produce as much as 232 Lumens per watt single watt in cool white colour.
This is far in excess of the light produced by incandescent bulbs (10-16 lumens per watt) or fluorescent tubes (60-100 Lumens per watt) which also do not provide precise and directional light distribution and so are wasteful light sources.
LED technology is advancing quickly. Costs continue to fall and luminous efficacy needs to be improved. Many energy experts are confident that LED lighting will dominate the future and that energy savings will be enormous.
LED lights have the ability to provide a more precise and directional light distribution and they are the most efficient light technology on the market. For more information’s please visit: LED lights vs. Others light
The life span of an LED lights is significantly longer than that of incandescent, fluorescent, metal halide or high pressure sodium lamp sources, generally lasting 50,000 hours or longer.
Although the LED lights never really burns out, product life span is measured by lumen depreciation. The Illuminating Engineering Society's (IES) current standard for calculating the life of an LED light is the point at which the LED light reaches 30 percent of lumen depreciation.
Remember, a life span rating is not equivalent to a lamp life rating. LED light life span corresponds to the point where it has reached 30 percent lumen depreciation. At the end of its life span an LED light would still be operating, but at a 30% decreased lumen output.
LED light sources can offer several potential benefits compared to metal halide, mercury vapour or fluorescent lighting.
These benefits fall into 6 main categories, as follows:
The cost of installing LED high bay lighting, LED Flood lighting and LED Street lighting is higher, but the improvement in quality and the cost savings later on usually more than justify the investment Ultimately, LED lighting is more environmentally friendly and provides higher light quality than other lighting options.
Installing LED lights will almost certainly increase your bottom-line profit, while significantly reducing the carbon emissions associated with the electricity you consume.
LED lights are inherently directional light sources and offer better optical control than alternative older light sources like fluorescent, metal halide, mercury vapour and high pressure sodium lamps.
