The LED applications

Decorative lighting
Due to the rich variety in colors, small size, durability, energy savings, LEDs are perfect light source for decorative application. Attached on a PCB, flexible cable, or other desired materials; LEDs can be used for light source of channel letter, signs, border light, light tube and so on.

Illumination
With the advance of the white light LED technology, an array of white light LEDs assembled in a certain way are now bright enough to be used for domestic illumination, such as light, table lamp, and garden lamp etc.

Display
A typical application of LEDs is for message display or large-scale display screen, which are popularity used in sport fields, airports, business centers and so on. The largest LED display in the world is 36mm high, at Times Square,Manhattan.

LCD backlight
Because of LED's small size and low power consumption, they are perfect light source for LCD backlight.

Color
Monochromaticity is the inherent property of LEDs. They emit a pure color in a narrow frequency range. The color emitted from a LED is identified by peak wavelength(Ipk) and measured in nanometers(nm).Peak wavelength is a function of the LED chip material, the composition of the different materials determines the wavelength and therefore the color of light emitted.

As we know, white color is a combination of all colors. But eye does not require a mixture of all the colors of the spectrum to perceive white light.A mixture of three primary colors(red, green, blue) can be well enough.

Based on this principle, many solutions have been proposed to fabricate white color LEDs. The typical one is to bury a GaN type blue LED having an InGaN active layer into a YAG pond emitting yellow fluorescene.

The LED Application In The Automobiles

From LEDInside
With the influence of the economic crisis, the price of the LED products is decreasing, especially in the fourth quarter of 2008. But it can not stop its market demand. Both the LED lights and the backlight products are trying to occupy the market share. The high luminance LED will become the main characteristic of the future automobiles, which is due to the outstanding advantages of the LED. What is more, using the LED illumination can alternate the design of the automobiles. Because of its advantages, the LED is widely applied to construct a comfortable environment in the car, such as the indicator, navigation light and the treadle illuminative light. And the flat-panel display will increase the application of LED further.

Recently, the LED automotive lights are promising in the electric industry. The LED automotive light is energy saving and with high-luminance, which is becoming the advantages to occupy the market. The high-luminance of the LED enables it to adapt more crucial environment. The light can secure the safety of the car at night. LED light can be used to replace the halogen light, which is more effective and colorful. The beautiful appearance attracts so many young customers.

The LED has offered a great business opportunity with its unique advantages, attracting so many manufacturers to take the backlight market, especially the flat-panel display and the liquid crystal display market. Changing the CCFL backlight into the LED backlight will be a new emerging market. Experts point out that the development LED backlight is very promising. The performance of the LED chip is increasing and the cost is reducing, so the LED will become the mainly backlight technology of the liquid crystal display. What is more, the Car electronic products are also promising, such as the car navigation system and radar. If the LED backlight technology can be used in these systems, these systems will be more competitive.

About LED Sign

LED sign display is a large display system with the collection of microelectronics technology, optoelectronic technology, computer technology and information processing technology. With its colourful, wide dynamic range, high brightness, long life and stable job performance,it has become the best display media in the workforce, and widely used in advertising, securities, information dissemination, press conference and so on.Nowadays,it becomes the great international advanced display media.

The LED display is a display screen devices composed of LED component array,used for displaying all kinds of information (such as text, graphics, images, video, animation, prices, the video signal etc) through certain control mode.

As the evolution of displaying methods,the historical and traditional lamp--filament lamp cannot overcome its defects,such as large power, short life. And the neon lights, advertisements, graphic signs advertising are colorful, but change hardly and will not play video advertisement. Magnetic counterpart although can assemble simple pattern by computer, do not have illuminant so that it has poor performance at night. In recent years, along with microelectronics technology, automation technology, the rapid development of computer technology, production process and the application of new materials, LED chips has high brightness and longe life, thus the LED application field are increasingly broad,and the LED display market get considerable development. After 1993,the apearance of super bright blue, red, green luminescence tubes, make the dream of true color screen come true,and outdoor LED screen get people's love, especially in the fields of sports venues, advertising, news etc,and become more widely used. From the future development trend, the current video effect has several media, its performance advantage anima, cathode tubes (CRTS) or quartz tube (DV) large TV: cost is very expensive and size are restricted(the large one are usually only 37 inch).

Colored liquid crystal display (LCD): expensive, circuit complex,the small area, and the visible angle is small, but the picture is exquisite, visual feeling good.
Image projection equipment(Projector): the brightness is very short, legibility is poor,but convenient installation and easy maintenance.
TV Wall: the surface has halving line,and the outdoor applications have poor effect in brightness, not suitable for representing text, but have good performance in the house.
LED sign: LED Sign has little limitation by space,and can be designed according to user requirement of display size, it also has full color effect, wide viewing angle, can show words, design, image (including animation and video).

With the rapid economic growth in China, for the higher requirements of information dissemination. We can believe that LED display,for its bright color, displaying large volume, long service life,low power consumption, light, small space, high stability, easy to operate, easy installation and maintenance etc, will play more and more important role in the social economy development. In a word, the LED sign is your best choice in today's display media.
