The History of Lighting
Currently the LED light is popular as a result of it's efficiency as well as it's 'brand-new' modern technology. The LED has actually been around for over 50 years. The recent increase of white LEDs is what has brought it into the public eye as a replacement for various other white lights.
In the beginning (RED):
LEDs obtained their beginning as lights for circuit boards as well as small electric tools. Early lights were very durable, had a fairly low lumen output, and were extremely energy effective. In 1961, Gary Pittman and also Bob Biard from Texas Instruments found that gallium-arsenide diode emits infrared light every time it is connected to current. The same year they obtained a patent for infrared LED. Nick Holonyak Jr. established in 1962 the first light-emitting diode that sent out light in the visible part of the frequency range. It was a red LED.
LEDs (BLUE):
LEDs were limited in replacing fluorescent light bulbs as well as neon in lighted signs. It had not been until 1976 that the first 'high' illumination LED was developed by T P Pearsall that could use fibre optic telecommunications. The discovery of blue LED resulted in a much more efficient means to generate white light but the very first ones that were produced were very costly and not readily available.
LEDs (Green):
Throughout the mid-1970s, researchers started utilizing only Gallium Phosphide to make LEDs that released a light green light. These experiments caused enhanced variations of LEDs by the end of the decade. These LEDs could create pure green light. The LED-based lights readily available today aim the blue light at a phosphor, which then emits green light.
LED 21st Century (White):
The 2014 Nobel Prize for physics was granted to three scientists in Japan and the US for the development of blue light emitting diodes (LEDs).
Although red and also green LEDs had actually been around for several years, blue LEDs were a long-lasting difficulty for scientists in both academic community and industry. Without them, the three colors could not be mixed to produce the white light we currently see in LED-based computer system and TV screens. In addition, the high-energy blue light can be used to excite phosphorus as well as directly generate white light - the basis of the next generation of light bulb.
Gradually LEDs have become brighter and also more reliable. Second generation LED technology has the capability to string multiple LEDs into a single circuit. In time, LEDs also came to be preferable for outside use.
Many businesses today are starting to change to LED light with the benefit that it is more environmentally friendly as well as cost effective over time.
Introduction & History of Light Bulbs & Lighting
When was Lighting & Light Bulbs introduced to our world? When and where did it all start?
The carbon arc was the very first functional electric light, invented by Humphry Davy around 1805. He experimented with electrical energy as well as invented an electric battery. When he attached cables to his battery and a piece of carbon, the carbon glowed, generating light. His invention was called the Electric Arc lamp. Although it produced light, it didn't produce it for long and was too intense for functional use. It was used commercially in the 1870s for large buildings and road lighting till it was superseded in the early 20th century by the incandescent light.
How has lighting evolved over the years? (recap from Original light bulb to now with Smart Bulbs
"Thomas Edison patented the very first commercially successful bulb in 1879. In January 1879, at his research laboratory in Menlo Park, New Jersey, Edison had constructed his very first high resistance, incandescent electrical light. It worked by passing power through a slim platinum filament in the glass vacuum light bulb, which delayed the filament from melting. It wasn't until several months after the patent was granted that Edison and his team realized that a carbonized bamboo filament could last over 1200 hrs. This exploration marked the beginning of readily manufactured light bulbs in 1880. Thus Thomas Edison's firm, Edison Electric Light Firm, started marketing its new product.
Now fast forward to modern day, and unfortunately for the incandescent light bulb, regulation in numerous countries, including the United States, has mandated phasing it out for more energy-efficient alternative such as compact fluorescent lamps and LED lights. There has been much resistance, nevertheless, to these plans owing to the affordability of incandescent light bulbs, and the instant availability of incandescent lights. But there are concerns with mercury contamination with CFS, and with LED prices falling significantly, the future does appear to belong to the LED."
The Future is LED.
LEDs last longer. Some can last up to 100,000 hours (or over thirty years) without breaking down. LEDs are a lot more energy and cost efficient. These lights can minimize electrical power consumption as well as cost by approximately 80%. With LED's, people get to appreciate conveniences like dimming capabilities, changing light shades, immediate switching, no heating, and balanced light distribution. A lot of countries now have a ban on incandescent light bulbs. LEDs are kinder to the environment as well as greener than various other light technologies.
