The five main applications of LED and their application topics

Application 1: Backlight LCD backlight market is one of the largest application markets for LED products, mainly concentrated in the backlight of TFT color screens. LED backlight has good color rendering characteristics and is environmentally friendly, and is the mainstream of the LCD backlight market.
LED backlight has been successfully applied to PDA products such as mobile phones, and in 2004, the market exceeded 10 billion yuan. In recent years, the growth of mobile phone production has slowed down. At the same time, OLED has a low cost and has a tendency to replace small-size LCDs. It is expected that the absolute value of the demand for small-size LCD backlight will still be large, but the growth rate will decline. The future market hotspot of LED backlight will be in the large-size LCD market, and it will maintain high-speed growth with the rapid development of the LCD flat panel display market. At the same time, developed countries have begun to formulate regulations to restrict the use of non-environmentally friendly CCFL tubes, which will stimulate the faster development of LED backlight.
At present, the LED backlight of 7-inch screens has matured. With the continuous improvement of LED luminous efficiency, it will definitely be applied to notebook computers, computer monitors and LCD-TVs with larger LCD screens, and the market potential is unlimited. It is reported that OSRAM has recently launched an 82-inch LED backlight concept product that can produce a brightness of 10,000cd per square meter and a color saturation that is 50% higher than traditional CCFL light sources.

Application 2: Automobile Automobile will also be a high-growth market for LED products. Developed countries are vigorously developing automotive LED lights because LED lights have the advantages of energy saving, small size and flat installation, fast response, easy computer control, and shock resistance.
The application range ranges from display panels, decorative lights, and lighting lights inside the car to brake lights, turn signals, and indicator lights outside the car. Several well-known international lighting companies have launched conceptual products for headlights. The latest report is that Japan's Nishitetsu Electronics Co., Ltd. has successfully developed LED modules suitable for headlights, and 3.5W can produce a 245lm beam. Due to the high threshold of the automotive market, the automotive LED market is currently mainly occupied by HP, OSRAM, SIEMENS and several Japanese companies, and Taiwan's optoelectronic companies also occupy a part of the market share. This year, China's automobile production ranks third in the world, and will continue to grow rapidly in the future, so there is a lot to do in the automotive market for developing LED products.

Application 3: Light color lighting The light color lighting market mainly includes the outdoor landscape lighting market and the indoor decorative lighting market.
The outdoor landscape lighting market is mainly composed of guardrail lights, high-power floodlights, digital walls, underground lights, tree-shaped lights, colored lights, etc. It is currently a hot market in China. In particular, the construction of the five national lighting engineering demonstration bases has been given key support by local governments, which has effectively promoted the development of the LED lighting industry. For example, the Xiamen Municipal Government seized the favorable opportunity of the 2005 China (Xiamen) International Semiconductor Lighting Forum in April this year and the Investment and Trade Fair in September to complete two LED lighting demonstration projects, which were a complete success and expanded the influence of the Xiamen LED lighting engineering demonstration base. Then, it took advantage of the opportunity to launch the 2006 Spring Festival lighting project, providing local optoelectronic companies with excellent development opportunities. The 2008 Beijing Olympic Games and the 2010 Shanghai World Expo will further drive the growth of the LED light color market. But to pursue perfection and take the overall effect to the next level, landscape design is the key.

The interior decoration lighting market is currently focused on the application of indoor atmosphere lighting, making full use of the characteristics of LED lights, such as easy intelligent control and rich colors, to create an atmosphere in bars, shopping malls, etc. When the LED luminous efficiency reaches a certain level, the color temperature of LED lights can be adjusted through intelligent control. At that time, people can choose the best atmosphere lighting according to their mood, which greatly improves people's quality of life and creates huge market opportunities.

Application 4: Special lighting lamps The special lighting lamp market takes advantage of the characteristics of LED lamps, such as low power consumption, low driving voltage, cold light source, low ultraviolet component, and monochromaticity, to achieve various special lighting functions. The main varieties include explosion-proof lamps (including mining lamps), military special lamps, flashlights, emergency lights, flashlights, cultural relics and artwork lighting lamps, leather and jewelry decorative lamps, special medical lamps, crop growth lamps, solar LED lamps, etc. Among them, the National Safety Production Management Office has issued a document requiring all coal mines to use LED mining lamps. Mobile phones and digital cameras are gradually expanding the use of LED flashlights, indicating that these two LED products will present huge market development opportunities.
Solar LED lamps are a combination of energy-saving LEDs and solar cells. They are a perfect match and a good product that truly embodies the circular economy concept advocated by the country. At present, the market hotspots are mainly concentrated on solar high pole street lamps. Many domestic companies have developed 50W~80WLED modules with 1WLED as a unit. Once they can achieve truly commercial products, they will have great economic and social benefits.

Application 5: Traditional Market The traditional market mainly includes the display screen market and the signal light market.
The display screen market had a market of about 3 billion yuan in China in 2004. At present, with the rise of intelligent traffic information display and more communities and enterprises choosing LED display screens for publicity, the market still maintains a growth rate of 20% per year.
The signal light market, in 2004, the domestic road traffic light market alone had a market of 600 million yuan. The inherent directional characteristics of LED lights and the annual improvement of LED luminous efficiency will promote the development of LED signal light applications in railways, airports, shipping, etc. How to improve market opportunities in the industry? With the continuous improvement of LED performance and the continuous improvement of people's innovation ability and innovation awareness, there will be more, bigger and better market opportunities in the application market of LED products.
