Fast PVC rolling door can be designed according to the needs of customers. These doors can be used in firms, inside or outside. The fact that it is not used on a fixed area provides a flexible usage possibility. According to the needs of the firms, they can easily choose PVC rolling doors in the building areas. In addition, it can be used in exterior areas and provides a wide usage area. Fast PVC rolling door can be produced by coating fabric. The different colors of the fabric can be helpful in separating parts of the business. The function of the tarps is not only aesthetic, but also contributes to the protection of the door system against impacts. Since the impacts of the fabric do not come into direct contact with the door surface, it is inevitable that the door will be protected and long-lasting. The fabric can be a very important material so that the door receives as little damage as possible from impacts. Of course the fabric is resistant to a certain level of impact and there is also the possibility of damaging the fabric. You can contact our company for repair of PVC Fabric Roll Up Door.

Development status and prospects of solar LED lighting applications
Concerns about the security of energy supply and the response to climate change have gradually been gradually valued by countries around the world with the development of human society, and each has begun to adopt various means to achieve sustainable energy development. Indirectly promoted the rapid development of renewable energy technologies and industries worldwide, such as photovoltaic power generation, wind power generation and other annual growth rates are above 20. Although renewable energy has now diversified its energy sources, coal and crude oil remain hot spots in the international energy arena. As of the first half of 2014, China's hydropower installed capacity reached 290 million kilowatts, wind power installed capacity reached 83 million kilowatts, and solar power installed capacity reached 22 million kilowatts. Among them, renewable energy power generation installed more than 30 of all power generation installed capacity, renewable energy generation exceeds all power generation. 20. Renewable energy development as a major energy source has gradually become a hot spot in the international energy field, and has been widely used in many countries around the world. attention. A big step forward in green environmental protection As the earth's resources become increasingly scarce, the investment cost of basic energy is rising, and various safety and pollution risks are everywhere. Solar energy is an inexhaustible safety. Environmentally friendly new energy is getting more and more attention. At the same time, with the development and progress of solar photovoltaic technology, solar lighting products have double advantages in environmental protection and energy conservation, and the application of solar street lamps, garden lamps and lawn lamps has gradually formed scale. The development of solar power in the field of street lighting has been gradually improved. . As a green light source, LED light source has the characteristics of high luminous efficiency, low power consumption, long service life, and high safety and reliability. LED single tube power 0.03 ~ 0.06 watts, using DC drive, single tube drive voltage 1.5 ~ 3.5 volts, current 15 ~ 18 mA, fast response, high frequency operation. In the same lighting effect, the power consumption is one ten-thousandth of that of an incandescent light bulb. One-half of the fluorescent tube, Japan estimates that if the LED is twice as high as the fluorescent light, it replaces half of the Japanese incandescent lamp. Fluorescent light. It can save equivalent to 6 billion liters of crude oil per year. As for the bridge guardrail lamp, the same effect of a fluorescent lamp is more than 40 watts, and the power of each LED is only 8 watts, and can be changed in color. With the economic development, China's lighting power will be greatly improved, and the research and application of green energy-saving lighting will be paid more and more attention. On this basis, some people began to associate LED light sources with solar energy, hoping to make night lighting seamlessly connect with solar energy reserves during the day. This will be a big step for greening. At present, lighting consumption accounts for about 20% of the total power consumption. Reducing lighting power is an important way to save energy. In order to achieve this goal, the industry has researched and developed a variety of energy-saving lighting fixtures, and achieved certain results. However, the requirements for green lighting are still far away, and it is imperative to develop and apply new light sources that are more efficient, reliable, safe and durable. As a cold light source product, solar LED lighting fixture has the characteristics of high cost performance, environmental protection, safety and reliability, stable quality, long service life, easy installation and maintenance, etc. It can be widely used in green space lighting, highway lighting, advertising light box lighting, urban modeling landscape. Lighting and home lighting systems, but the high investment in solar LED lighting is a bottleneck. Development status of solar energy and LED light source technology Solar LED street light is mainly composed of solar battery module part (including bracket), LED lamp head, control box (with controller, battery) and lamp pole; solar panel light efficiency reaches 127Wp/ M2, high efficiency, very favorable for the wind-resistant design of the system; LED light source uses a single high-power LED (30W-100W) as the light source, using a unique multi-chip integrated single-module light source design, using imported high Brightness chip. The control box body is made of stainless steel, which is beautiful and durable. The maintenance-free lead-acid battery and charge and discharge controller are placed in the control box. This system uses valve-regulated sealed lead-acid battery. Because it has little maintenance, it is also called maintenance-free battery, which is beneficial to the system maintenance cost reduction. The charge and discharge controller is designed with all functions in mind (with light control, Time control, overcharge protection, over discharge protection and reverse connection protection, etc.) and cost control, achieving high cost performance. At this stage, common solar LED light sources are solar LED lawn lights, solar LED street lights and solar LED lights. In the wooden trestle of the south bank of Zhangjiang in the downtown area of ​​Zhangzhou, the solar street lights form a series of golden necklaces, which not only integrates functional lighting and landscape viewing, but also enhances the taste of green leisure facilities in the central city. In Ruijin, LED lights have also been widely used due to their outstanding energy-saving advantages. More than 100 kilometers away, at the entrance of the fourth middle school of Ruijin City, the original high-energy sodium lamps were all replaced with LED lights, which not only avoided the construction problems caused by the complicated road lighting reconstruction lines, but also greatly improved the night lighting environment in the road sections. .
