The third revolution: LED semiconductor lighting


 
Electronics,Science & Technology,Business News
Since the world's first semiconductor light-emitting diode was born in the 1960s, due to LED lighting has long life, energy saving, colorful, safety, environmental characteristics, LED is known as the hoping lighting in the history of mankind.

Emitting diode LED development history:

In 1907, Henry Joseph Round firstly observed phenomenon on a silicon electroluminescence.

In 1936, George Destiau released a report about ZnS powder emitting light. With the current applications and extensive acknowledge,eventually emerge the "electroluminescence".

In 1955, Rubin Braunstein who worked in the Radio Corporation of America (Radio Corporation of America) found a gallium arsenide (GaAs) and other semiconductor alloys with infrared radiation effects.

In 1962, GE, Monsanto, IBM's joint laboratory developed a 655nm GaAsP (GaAsP) semiconductor compounds that emit red,from then on,light-emitting diodes entered commercial development process.

In 1965, Monsanto and Hewlett-Packard introduced commercially Red LED that was made out of GaAsP materials, then this LED light efficiency is about 0.1 lumens per watt.

In 1968, LED lights had made breakthroughs in research and development, the use of nitrogen-doped GaAsP technology made the efficiency of the device reaches a lumens / watt, LED energy-saving lamps can emit red, orange and yellow light.

In 1971, GaP green chip LED with the same efficiency was launched, LED began to be widely used in digital technology applications with text display area.

In the early 1980s,the technological breakthrough was developing AlGaAs LED,which can be emitted red light at 10 lumens per watt luminous efficiency. LED lights began to be used outdoors as well as information dissemination and car brake light (CHMSL) devices.

In 1990, equivalent to the best device performance red AlInGaP technology was provided, which was 10 times higher than the standard of GaAsP device performance.

In 1994, Shuji Nakamura, Japanese scientists in InGaN (indium gallium nitride) substrate only developed the first blue LED, which opened GaN-based LED light research and development boom, Blu-ray made the emergence of white LED is possible.

In the late 1990s, through the blue excitation YAG phosphor to produce white LED lights was developed, but the color was uneven, life was short, it had high price. As technology continues to progress into the 21st century,the white LED has been developing very rapidly,the white LED luminous efficiency of energy-saving lamps has been developing faster and faster, significantly more than incandescent and approach to fluorescent, the development of materials technology, the chip size and shape processes further increased several times for the commercialization of LED light flux. Ever feeble glow of the LED is now heralded a new era of LED lights.

From the invention of the LED to the now large area applications of the LED lights, LED gone through 106 years of history, from the initial silicon carbide to the current LED, LED evolutionary process is much more plentiful than the two types of lighting history, of course, compared to other two categories lighting, semiconductor lighting has a unique advantage and is the human manifestation of high-tech, which is closer to people's lives, LED lighting is mainly divided into indoor lighting and outdoor lighting, outdoor lighting is mainly LED flood light and LED tunnel lights and other led power lighting, interior lighting is mainly LED bulb and LED tube and other interior lighting. Meanwhile, good LED lighting is inseparable from good LED products manufacturer, Li Sida lighting is precisely providing professional lighting technology and attentive service, though Li Sida lighting www.lead-lighting.com is still a new star, what his customer-oriented goals and striving to produce high quality and eco-friendly LED lighting products have been unanimously praised by the people.
