Due to the advantages of energy saving, no stroboscopic, no noise, no easy fatigue, LED lighting is off, LLF launches high-bright low-power LED lighting equipment, and Zetex's new LED lighting driver effectively increases power density. 3. Zetex's new LED lighting Drives effectively increase power density 4, high-power LED lighting technology seminar Yuyao held 5, Accumulation Technology successfully built high-efficiency constant current mode DC/DC converter for LED lighting 6, power plant Dafang: next year, the product line will extend to the diffusion film And LED lighting industry 7, LED lighting import trend is gradually clear, optical component factory downtime layout 8, using liquid crystal light guide to solve LED lighting equipment problems, Hitachi Lighting will be listed new products 9, Osram will increase OLED lighting efficiency to 46 lumens / watt Life expectancy of 5,000 hours 10, pay attention to the Chinese market, Osram executives talk about the development trend of LED lighting has been rapidly developed in the field of public lighting, and will be active in the field of home lighting. In 2012, China's LED indoor lighting market was 33.5 billion yuan, an increase of 80% year-on-year. Among them, LED commercial lighting contributed about 60, and the market scale exceeded 20 billion yuan.
According to the survey data, the sales volume of China's LED lamp market reached 10 billion yuan in 2012 (excluding Hong Kong and Taiwan), an increase of 92 billion yuan compared with 5.2 billion yuan in 2011. The sales volume of LED lamp market will reach 16.1 billion yuan in 2013. . Market demand will continue to be strong. It is estimated that by 2017, the LED lamp market will reach 44.5 billion yuan. Although the LED lighting market is gradually increasing, due to price, quality and other factors, LED lighting products will take time to completely occupy the civilian market. Wu Ling, director of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said: At present, the quality of domestic LED products is still poor, light efficiency, light quality improvement and cost reduction are still LED shutdown, TI introduced 28V constant current white LED driver and LCD High-voltage boost regulators for voltage converters 2 and NS support DSL modems and white LEDs
3, Sipex's boost converter can drive up to 8 LEDs in series
4, Yingmei LED color printer new product promotion meeting held in Shenzhen 5, LED: bring car head-up display 6, Sprinter's DC / DC converter can drive up to 20 LED
In 2003, the high-brightness LED market grew by 30. The three major applications are the main 8 and Wuliangye diversification strategy: no chip to do OLED display 9. Vishay is authorized by Osram white LED technology, enter automotive lighting 10, OLED is expected to be LCD A fight, patents and standards around the industry to develop the main trend of lighting development.
As prices continue to fall, the competition in the LED industry is becoming increasingly fierce. The LED lighting industry is entering the stage of price and quality competition. Some experts in the industry pointed out that the price of LED products is declining at a rate of about 20 per year, and the focus of future industry competition will shift to product quality and service. In the face of products of the same price, companies began to look for more energy-efficient and durable lighting products.
On September 1, the EU's "Energy Efficiency Regulations for LED Lighting Products" came into effect. According to the EU's Latest Energy Efficiency Regulations for LED Lighting Products, CEMark for lamps and luminaires requires the addition of the ErP(EU)No1194/2012 directive and the Energy Efficiency Label (EU) No874/2012 directive based on the LVD Directive and the EMC Directive for LEDs. The functionality, safety and energy efficiency of the lamp and its equipment are all higher requirements. The EU is a key market for the export of LED lighting products in China. Therefore, how to improve the quality of LED lighting will become a key issue for domestic enterprises.
Pay attention to LED technology innovation and better promote the development of China's LED lighting industry. The Big Bit Information Agency will hold the 9th LED General Lighting Drive Technology Seminar in Shenzhen on October 25. At that time, the conference organizer Dabit Information Institute will invite Dr. Qian Keyuan from the Semiconductor Lighting Laboratory of Shenzhen Research Institute of Tsinghua University to bring the explanation of "Design of Optical System for Improving LED Lighting Quality".
Concrete Pile Pre-stressed/Tension Machine:
Tension Machine is a kind of feedthrough pre-tensioing. It is also called Spun Pile tension jack machine, Pole Tension Machine, prestressed tension machine etc. It is the neccesary equipment to produce Pre-stressed Concrete Spun Pile and prestressed concrete pole products. As the end of the tension rod is connected to the anchor with thread, it can be applied to various forged anchors, chilled iron anchor used for stayed-cable bridge and other similar anchors, as well as pre-tension pulling for pipes. In accordance with actual requirement.
HH Tension Machine's advantages:
1. The large-screen LCD display.
2. Double control mechanism of touch screen and keyboard, high reliability.
3. Directly work after the input of tensioning data, and the oil cylinder will automatically complete the tensioning process to reduce uncertain factor of manual operations and improve the tensile quality.
4. Built-in SD card function, which can save the tensile data to the computer regularly, and check the record at any time.
5. With its own printer, it can print tensile data in working time, avoiding the tedious and unstable manual record and ensuring the traceability of tensegrity data is verified.
Technical Parameter:
1. Oil pump flow: 12L/min
2. Motor power: 7.5kw
3. Rated power: 31.5Kpa
4.Tension force: 2000KN
5. Tension stroke: 200mm
6. Programmable controller of automatic control system + input and output of analog data Color touch screen, USB interface output
7. Control voltage: 380V+24V
8. Accuracy of prestress control:±0.1Mpa
9. Data transmission rate is 100%
Main configuration:
Automatic tension control system, 300T jack, oil pump, lifting trolley, tensioning rod, tensioning head and supporting foot
