At first, LED was only used as a miniature light fixture in high-end devices such as computers, audio and video recorders. With the advancement of large-scale integrated circuits and computer technology, LED displays are rapidly rising. As a new generation of display media, LED has become a beautiful scenery in modern cities and is widely used in various public places. In recent years, LED has gradually become popular in general lighting applications, from inventory to antiques, from laptops to digital cameras PDA、 From indoor lighting to car lighting, LED is ubiquitous in mobile phones.
The emergence of high brightness LED is a milestone, and it will be one of the greatest inventions of humanity after Thomas Edison invented the incandescent light bulb. In the early development of LEDs, only red light was emitted, which was used in electronic devices. Nowadays, LEDs can emit various light beams such as red, yellow, blue, green, orange, amber, blue-green turquoise, red, green, turquoise color, yellow green, pure green, green, white, etc. In every city in China, there is a dazzling light of LED everywhere, and LED is changing our living and working environment.
After the microelectronics revolution, semiconductor technology gave birth to a new industrial revolution - the lighting revolution. LED has become a shining symbol of the information age and will gradually replace traditional lighting technologies such as incandescent lamps and fluorescent lamps.
Outstanding advantages and wide range of applications
For people in Times Square, New York, they may not forget that the Coca Cola advertisement is clear, colorful, and lifelike, constantly changing under the control of computer graphics. In fact, as early as the 1990s, LED illuminated billboards or street lights appeared on airports and highways in Munich, Germany, France, and Spain. During maintenance, there was no need to hang open light boxes, as long as the light tube light box used for illumination on the ground could replace the light source.
LED Charm 4 beats, with many advantages. In addition to long lifespan and low power consumption, LED has three advantages: firstly, it is very flexible in application, which can make it suitable for various thin and short products such as dots, lines, and surfaces; The second is better environmental benefits, because there is no UV and infrared spectrum, no heat, no radiation, which belongs to typical green lighting sources, and waste recycling without pollution; 3、 The control is very convenient, just adjust the current, and you can choose dimming. The combination of different light colors is varied, and the use of sequential control circuits can achieve more diverse and dynamic changing effects.
LED can be used not only for large-scale advertising displays, but also for building and transportation lighting. As a key building for urban lighting, LED's contour can support your things and simulate any color, greatly reducing light loss and maintenance costs. Due to its small size, LED is used from production lines to lighting fixtures, and is used to complete ground lights, direction lights, walkways, and lanes. It is safe, reliable, and durable. In the past, neon lights may have been the most charming in the city sky. However, due to their susceptibility to damage, we often see that the images and text displayed by neon lights always lack arms. If LED neon lights are used instead of display signs, not only can incomplete regrets be avoided, but also the desired state can be achieved.
The response speed of a single component in an organic LED display screen is 1000 times faster than that of an LCD screen, and it can be viewed comfortably under light and adapt to temperatures below 40 degrees Celsius. It is reported that foreign companies are developing a head stealing viewfinder, which includes a high-resolution organic LED display screen in the size of ZhiJiaGai. Wearing a semi transparent helmet display screen, pilots can easily view various flight data; Surgery allows surgeons to view complex diagnostic images without leaving the operating table; When a flight mechanic is inspecting an aircraft, their eyes can see the corresponding component maintenance manual. More and more tempting, wearing glasses made of organic LED display screens can also open your happy heart and watch movies at an angle of up to 160 degrees.
