At present, the global LED industry investment is a very hot key project, and countries pay more attention to the R&D and production of LED. Japan has achieved a white light of 5 billion yen in 1998-2002, and the budget for the entire plan is 6 billion yen. The "Next Generation Lighting Plan" developed by the United States in 2000 was included in the Energy Act. It plans to invest $500 million from 2000-2010 to replace 55% of incandescent and fluorescent lamps with LEDs. It is expected that by 2025, solid-state lighting sources will The use will reduce lighting power consumption by half, saving $35 billion annually, forming a semiconductor lighting industry market with an annual output value of more than $50 billion. China is also accelerating the pace of LED development. China is a big electronics manufacturing industry and is developing rapidly. The domestic mobile phone and automobile industries are the driving force for LED development. With the development of national semiconductor lighting engineering, the domestic LED industry has broad development prospects. In the next five years, China will also promote semiconductor lighting as a major project; the Ministry of Science and Technology has also approved Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Shijiazhuang and Yangzhou as LED industrialization bases.
In the future, LED automotive lighting demand will grow steadily.
As the growth rate of the mobile phone market slows down, the growth momentum of the LED market will turn into notebook computer backlights, display billboards, lighting and other applications. In terms of automotive lighting, LED long-term demand will grow steadily.
Due to the decline in LED prices and the increase in luminous efficiency, LEDs have evolved from in-vehicle lighting to third-hand lights, directional lights, and taillights. In 2008, they introduced headlights in premium vehicles. At present, the luminous efficiency of LED lamps has been higher than that of traditional car headlights, which means that LED headlights have the opportunity to formally enter into commercialization. The mediation price is still high, so it will only be deployed in high-end models in the short term.
In the past two years, with the improvement of LED luminous efficiency and price drop, the application range of products has become wider. Netbook has been equipped with a large number of LEDs as backlights, and LED street lamps and landscape lighting applications will continue to flourish.
In the future, ultra-thin TVs basically use LED backlight technology.
With the continuous improvement of flat panel display technology, ultra-thin TVs will be thinner. From the current market, ultra-thin TVs basically use LED backlights. The LED industry is known as LEDs. It was recognized as the next-generation lighting application source after it was born in the 1960s.
The LED light source not only greatly reduces the thickness and weight of the TV, but also has higher reliability and stability. In terms of luminescence lifetime, the rated life of different CCFLs (semi-bright) is between 8,000 and 100,000 hours, while LEDs can reach about twice the CCFL. LED TVs have a service life of up to 100,000 hours. If you press 5 hours a day, an LED TV can be used for nearly 55 years.
Since the second half of 2008, major flat-panel TV manufacturers have begun to promote LED TV as a high-end product. For example, Samsung, Sharp, Sony, Hisense and other brands have successively released new products using LED technology. At the 2009 CES show, both Japanese and Korean companies such as Samsung, Sony, and LG, as well as Chinese companies such as Hisense, Konka, and Haier, exhibited their own LED TVs. Some time ago, the domestic color TV company Hisense also announced the establishment of an LED module production line. Since then, Tsinghua Tongfang has also indicated that it will raise 2 billion yuan to focus on LED. The investment of these manufacturers in the LED field will surely realize the dream of LED becoming mainstream. .
In addition to LEDs, there are currently OLEDs in the field of television. OLEDs are organic light-emitting diodes, also known as organic electro-laser displays because of their thinness and power saving. However, OLEDs still face many technical and production cost problems, and OLEDs will take at least four to five years to enter the market. From this trend, ultra-thin TVs are just getting started, and ultra-thin TVs will be thinner, better in quality and longer in life.
Overall, China's future LED market will continue to grow. This is a good market opportunity for companies engaged in the production of lighting soft ferrite cores in China.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
