As the third generation of revolutionary lighting source after incandescent lamps and fluorescent lamps, LED lighting has attracted much attention since its inception and has become a new star in the lighting industry. Along with the rapid development of LED lighting technology, the LED lighting wings are gradually becoming more and more, and it is beyond the incandescent lamp and fluorescent lamp, and is promoted to be the main ship of the lighting industry.
The great prospects of LED lighting have been widely recognized by the world, and a wave of development of LED lighting has emerged around the world. However, looking at the global LED lighting camp, China's LED lighting, which is led by quantity, has been criticized for its quality and continues to stay in the third step of LED lighting. Survival and embarrassment have become a real portrayal of China's LED lighting companies in recent years, and a promotion breakthrough has come to the fore.
Industry development depends on domestic and foreign standards. Because China's LED industry started relatively late, intellectual property issues have always been the bottleneck of the industry's rapid catch-up. China's LED companies have also been swayed abroad as low-energy children with no rights, high yield and low rights. Recently, at the biennial 2014 Frankfurt International Lighting Exhibition, due to patent infringement, the two Chinese companies suffered from embarrassment and were forced to dismantle. This humiliation has hurt the hearts of domestic lighting people. Bypassing technical barriers and improving the hard power of LED companies has become the common aspiration of lighting people.
In addition to the international encounters, China's LED companies are also in danger of development in China, winning the sip but failing to win the hearts of the people, and the penetration rate of lighting products is extremely poor. Since there is no standard system for LED lighting from power supply to finished products, there is no requirement for mandatory testing and certification. The existing equipment and facilities of each enterprise, their respective work bases and technical levels are not balanced, resulting in the emergence of the market. LED lighting applications have a wide variety of products, different performance, and poor interchangeability. This also gives consumers a lack of confidence in the new lighting products such as LED lighting.
The so-called industrial development standards are the first. In view of the reality of the LED industry in China, Guangdong has taken the lead in proposing and implementing the LED lighting standard optical component plan, and adopting the standardization and modularization method of the light-emitting components as the reference unit, based on the versatility of LED lighting products. Compatibility, committed to solving LED key technologies and common problems. In addition, it will integrate advanced technologies and patents in the middle and lower reaches of the LED industry, form a standard alliance of LED lighting standard optical components, and realize the standardization of property rights to jointly resist foreign competition. The patent barriers and disputes for the fight for a greater international voice.
Since then, the establishment of LED-related standards and standards system has entered a stage of rapid development. In 2012, Guangdong Province established a standard optical component project team, and the first batch of 21 LED standard optical component series normative documents have been promoted to the market.
Taking advantage of the trend and entering the standardization and standardization of the new LED lighting, it provides the basis and convenience for the lighting application. The lighting companies have high hopes for the optical component standards, but they often drink more than practice and truly devote themselves to the optical component products. Enterprises are embarrassed, which has nothing to do with the inertia of domestic lighting companies. Everyone is still waiting to see the state, and there is no action.
Jingke Electronics took advantage of the trend and was the first to eat crabs. It was the first to invest in the Guangdong Standard Light Component Project Group to develop optical components. Jingdong Electronics Assistant President Song Dong is calm, optical components are the trend of the times, the development of optical components products is a matter of benefiting the country and benefiting others, not only can LED energy conservation and environmental protection take a new step, but also allow manufacturers and use Achieve a win-win situation. Manufacturers can achieve product serialization and large-scale production. Since parts can be used universally, this enhances compatibility and reduces the cost of design, production, and materials. Users can create different compatibility alternatives for large-scale procurement, while the maintenance of convenient features can also reduce procurement costs and risks. For the whole industry, the production of standard optical components can encourage manufacturers to achieve technical specialization and product specialization, which helps to establish an industrial chain, form a market segment, and promote the optimization of industrial resource allocation.
In order to develop standard optical component products at an early date, Jingke Electronics has spared no effort to invest a lot of manpower and material resources in the development of optical component project planning, top-level design and subsequent implementation plans, and has built a highly educated and research-oriented R&D capability. The team specializes in optical component products and has actively cooperated with the Guangdong Semiconductor Lighting Industry Joint Innovation Center to successfully develop core technology LED light components with international leading level.
Nowadays, the pace of research and development of optical components products is more and more firm, and the tentacles will extend to the LED lighting standard optical component level one, level two and other aspects. The SMD3014 developed by the company and the high-power ceramic products 3535 without gold wire package have passed the LM80. Certification, in the near future, has successfully passed the Guangdong Provincial Standard Certification and is officially applied to optical components.
As the lead unit of the LED standard optical component (level 1 package component) project in Guangdong Province, Jingke Electronics has taken the lead and shouldered the heavy responsibility of promoting the development of standard optical components. This kind of responsibility and courage will also make Jingke Electronics deeply rooted in the hearts of the people. Become a monument in the construction of standard optical components.
Welded Bed Plate For Flanges Of Ship Pipe
The flange welded single-sided seat plate is mainly installed on the top, side wall and bottom of the cabin or cabinet as the entrance and exit of the cabin or cabinet. Valves, accessories or pipes can be installed directly on the single-sided seat plate.
Flange welded single-sided seat plate is suitable for seawater, fresh water, oil, air and steam pipelines below 300 °C. The commonly used nominal diameter is 15~150 mm, and the nominal pressure is lower than 1.6 MPa. The shape of the single-sided seat plate is similar to the corresponding lap-welded Steel Flange.
Flange welded double-sided seat plates are generally used when pipelines pass through decks and tanks, and the two sides of the seat plate are respectively connected to valves, accessories or pipes.
Compared with the single-sided seat plate, the double-sided seat plate has an extra shoulder and double-sided mounting stud bolts. The outer diameter of the shoulder is 10~20 mm larger than that of the corresponding flange, and the thickness of the shoulder is 6~12 mm.
Its scope of application and other structural dimensions are basically the same as those of the single-sided seat plate.
The manufacturing and installation methods of the flange-welded double-sided seat plate are basically the same as the single-sided seat plate, but when the screw holes are drawn, the positions of the upper and lower screw holes of the seat plate must be staggered from each other and must not overlap; deck or bulkhead The diameter of the hole on the top is 2~3 mm larger than the diameter of the seat plate.
