CLP South passed a series of complicated tests by the UL Environmental Certification Agency and finally passed the certification. This proves its leading position in the international LED industry. China Southern is China's first LED company to use LED lamps in UL and CUL North American hazardous areas. "The head of the UL certification program, Zhong Qilin said.
Recently, the high-safety LED explosion-proof lamp independently developed by Shenzhen Zhongdian Southern Company passed the UL844 and CSA-C22.2NO.137 North American hazardous area lighting certification. CLP South became the first LED enterprise in China to receive this honor. At the same time, it also means that China's LED explosion-proof lamps have passed the most stringent testing in the world, ranking first in the international market.
It is understood that in the global use of electricity, lighting electricity accounts for about 19% of total electricity consumption. In recent years, in the initiative to take measures to reduce CO2 emissions to prevent the greenhouse effect, calls for reducing the power consumption of lighting fixtures are also increasing. In the global energy-saving and carbon-reduction trend, LED lighting is known as the light of the 21st century and is driving the fourth wave of lighting revolution.
At present, under the dual promotion of the Chinese government and the market, LED lighting with the goal of environmental protection, energy conservation and emission reduction has rapidly spread in the field of public lighting, and has rapidly penetrated into the commercial lighting, office lighting, and home lighting markets, which has also prompted LEDs to The share of the global lighting industry continues to climb and quickly enters the era of LED lighting.
"Development and promotion of high-efficiency, energy-saving and high-security explosion-proof LED lamps, in addition to focusing on the property and life safety of Chinese people in the field of explosion-proof, can meet the requirements of energy conservation, safety and environmental protection," said Tang Deming, chairman of China Southern Power.
Since the beginning of the 21st century, with the rapid development of China's petroleum, chemical, mining and other industries, the use of lighting fixtures in production, warehousing, and rescue has become more widespread, with more and more varieties. How to prevent accidental explosions of lighting fixtures is particularly important in explosive gas hazards.
According to reports, the LED explosion-proof lamps produced by CEC South can reduce electricity consumption by at least 80% compared with traditional explosion-proof lighting, saving more than 80% of electricity expenses.
“Because most of the original devices and materials of this project can be recycled and reused, and contain no harmful or toxic substances, the ecological environment has a good protection effect, and the comprehensive recycling and reuse of resources has been greatly improved.†Long Tang Deming said.
According to reports, over the years, CLP began to develop a green economy, achieve energy-saving emission reduction targets, and create a world-renowned explosion-proof lighting brand. It has gradually established a strong technical team and achieved many scientific research results.
Tang Deming, Chairman of CEC South, said, “Our company has high- and mid-level professor-level technical research talents. The company's series of products represent the leading level of similar products at home and abroad. All products have their own intellectual property rights and have achieved China and the world. The patent certificate has been marketed in more than 100 countries around the world and has obtained the CEC Southern CESP trademark."
At present, CLP South's products have passed ISO9001 quality system certification and ISO14001 environmental system certification. The products have obtained the certification of China's national lighting testing center, China's explosion-proof certification CNEX, European explosion-proof certification, and international explosion-proof certification. Products are widely used in petroleum, chemical, natural gas, aerospace, coal, electric railway, metallurgy, shipbuilding, public security, fire conservancy, municipal, telecommunications, diving, rescue and other more than 10 industries. It has been marketed in more than 100 countries and regions around the world. Many famous enterprises at home and abroad such as Sinopec and China Petroleum have become suppliers and partners of CLP South.
Not only has a good reputation in China, but also the explosion-proof products exported by China Southern Power has been recognized by developed countries. The key technical indicators such as explosion-proof performance, waterproof performance, anti-corrosion performance, anti-dust performance and life test of the products are ranked first in the world by the US government-designated UL and DLC testing centers.
According to public information, the US UL certification body is an independent professional organization for testing public safety. It was founded in 1894. In the initial stage, UL mainly relied on the fire insurance department to provide funds for operation. Until 1916, UL was completely independent. After nearly a hundred years of development, UL has become a world-renowned certification body with a complete set of strict organizational management system, standard development and product certification procedures. Therefore, industry insiders often refer to UL certification as the most stringent certification. In addition to the US UL, CUL, DLC, ETL, CETL and other authoritative certifications, the LED explosion-proof lamps have also obtained CE, ROHS, ATEX certifications in Europe, SAA and C-Tick certifications in Australia.
The Third Plenary Session of the 18th CPC Central Committee proposed to deepen the reform of the science and technology system, explicitly encourage original innovation, establish a synergy and innovation mechanism for industry, university and research, strengthen the main position of enterprises in technological innovation, strengthen the use and protection of intellectual property, and integrate scientific and technological planning and resources. This points out the direction for the sustainable development of China's semiconductor lighting strategy emerging industry.†Tang Deming, chairman of China Southern Power, believes that national policy supports the industry very much.
According to industry experts, “At present, the LED explosion-proof lamp market is in a period of rapid development. We are researching and developing high-safety explosion-proof lamps in a timely manner. After achieving the domestic first and domestic leading advantages, we continue to increase R&D investment and try to grasp Living in the development trend and leading the development of the industry. This will play a role in demonstrating the technological development of China's new materials industry, while at the same time reducing the power consumption and energy conservation and carbon reduction."
In recent years, in large-scale shopping malls or activities, we always see the figure of "LED fan". Its appearance is similar to the fan, but it can display various patterns when rotating, and some can display dynamic 3D patterns, which is very cool. Every time we see it, we can always make people stop and watch it, which plays a very good role in publicity and promotion. So how do LED fans display patterns?
Strictly speaking, this so-called "fan" is just a vivid way to call it. In fact, it is a kind of "rotating LED light bar", and its professional name is holographic 3D smart glare screen. After power on, the "fan blade" starts to rotate, which can present a 3D image at the same time, cool and lifelike. At the same time, according to the size and color of the pattern, the LED fan can well hide its leaves, because there is no frame and no fixed screen, so the dynamic picture is like floating in the air, very realistic.
The 3D smart screen not only uses the hardware of rotating LED, but also uses the visual persistence of human eyes. For the hardware equipment of rotating LED, simply speaking, it is to calculate the change frequency of LED light according to the rotation speed of "fan blade". When different LED lights are lit at different times, different patterns will appear. The so-called visual persistence refers to that when the human eye is observing the scene, the light signal is transmitted to the brain nerve, which takes a short period of time. After the end of the role of light, the visual image does not disappear immediately, and the human eye can still maintain its image for about 0.1-0.4 seconds. This kind of residual vision is called "afterimage". The visual phenomenon is called "visual persistence", and the single product can be unique. Vertical display effect can also display the overall effect in combination.
3D holographic fan screen application: shopping malls, brand stores, stores, airports, etc. A good choice to reflect brand effect and brand grade
Principle of 3D holographic screen: Generally speaking, one or more strings of LED lights are arranged on the fan blades. Here, it is assumed that there are 20 LED lights, which are numbered 1-20 at a time from the axis to the edge of the fan blades. In order to explain the principle briefly, we assume that when the fan speed is 60 laps per minute (in reality, the speed is much higher), the human eye will have visual persistence. Let's assume that the LED light is 0 degrees above the fan in 0 seconds. If you want to display the effect of 6:00 on the fan, the minute hand needs to point to the top and the hour hand needs to point to the bottom. It is necessary to turn on the number 1-20 to display minute hand in 0 second, turn on the number 1-10 to display hour hand in 0.5 second, turn on the number 1-20 to display minute hand in 1 second, turn on the number 1-10 to display hour hand in 1.5 second, and so on, so that the human eye will receive a complete picture of the clock at 6:00. For complex patterns, LED fans will have more complex structure and programming equipment. Through the combination of LED light bar rotation and visual persistence, people will see a dynamic 3D picture of the rotating LED fan.
3D holographic fan screen structure: the screen body mainly has light bars and, according to different ones, some have two. Add rotary motor, built-in 3D holographic system and information receiving system.
At present, the main application of 3D smart screen is advertising. Because of its editability and realistic display effect, it is believed that in the near future, it will be applied in more fields.
