The Development History of LED Lights

The Development History of LED Lights

As the most popular lighting fixtures, LED lights are widely used in commerce, industry, agriculture, and our lives, and their outstanding performance has won everyone's recognition. They are used as the main lighting facilities in homes, offices, supermarkets, garages, workshops, and other indoor places.

With the continuous development of LED technology, different types of LED lights and technologies are used in different fields to improve work efficiency and bring a better way of life. However, what did LED lights look like initially, do you want to know?

If you are using an LED light, you just need to open its cover and you will realize that the luminous objects inside are several small bulbs. This small bulb is where the light is generated, the light emitting diode that took a lot of time and overcame a lot of hardship to develop.

The birth of the concept of LED, dates back to the early 20th century, in 1907, a researcher from the United Kingdom, H.J. Round light difference to some semiconductors in the current through the light will be issued, but this light is not bright, can not bring practical value.

In the 1960s, scientists began to study and improve the brightness and reliability of the LED, through continuous research and experimentation, in continuous attempts, found that the use of new materials, such as gallium arsenide and gallium phosphide these materials, could make the brightness of the LED greatly improved. In the 20th century 80-90s, LED was gradually applied to life, indicator lights, digital displays optoelectronic devices, and other fields. With the continuous improvement of the process, LED brightness, and manufacturing cost is not short of reducing, began to enter the commercial field.

At this point in time, stage lights start stopped using traditional candles and incandescent lamps, and began to use LED lights as the main stage lights. Stage light factory also seized the opportunity to create stage lights of all shapes and colors.

What made LEDs commonplace was the breakthrough of white LEDs. Before, LEDs could only emit monochromatic light, which could not be applied in daily life. However, with the continuous efforts of scientific researchers, LEDs that emit white light have been successfully developed. Through the use of phosphor or mixing a variety of light-emitting materials, it is possible to make LEDs emit white light close to natural light. At this time LED has been commonly used in life. For example, LED store lighting, LED garage lighting, LED warehouse lighting, and LED home lighting, which is now the most popular use of LED lamps.

In the 21st century, the proposed concept of energy saving, environmental protection, and intelligence, so LED began a new direction of development. As more and more people's aware of environmental protection, LED, this life in the most common technology is bound to be improved and upgraded. the direction of development of LED is also gradually to clean energy and intelligent development. With the continuous improvement of LED technology, intelligent lighting systems, and dimmable color mixing technology is also more and more mature. You can adjust the LED lights in your home through your cell phone when you are working, and the emergence of dimmable LED lights has brought a better experience to more people.

Of course, the development of LED will not stop, a small LED will be applied to more fields. In the future, LED through the material, process, structure and other aspects of the enhancement, will be towards a brighter, more efficient, more environmentally friendly, smarter direction.
