Under the circumstances of world warming and energy shortages, energy conservation and carbon reduction seem to have become the common goal of mankind. Who can fully utilize the cheap, reliable and inexhaustible renewable energy, who can survive the future energy crisis. In the lighting design, in response to the trend of energy saving and carbon reduction, energy saving, high luminous rate, environmental protection, emission reduction, and long life have become the most important demands outside the lighting effect. The lighting made the night of the city romantic and fascinating, but it also caused huge public financial waste. Today, when the low-carbon economy is sweeping across the globe and the country is vigorously developing strategic emerging industries, the city's lighting landscape, known as the “graceful and luxuriousâ€, should also be turned into a green business – green lighting, to make the city shine at night. Go on a path that continues to be benign, not just illusory. Green lighting and "secondary energy saving" compete for glory The most critical issue with green lighting is the light source. Speaking of new light sources, this can not but mention the emerging green high-tech products - LED street lights, LED street lights have brought an epoch-making revolution to the lighting market. The prosperity of China's public green lighting led by LED street lights has begun to poke. Green, energy-saving, environmentally friendly, low-carbon, emission reduction and other LED lamps with multiple identities have begun to bite the traditional lighting of the river with unparalleled momentum. It is appropriate that the secondary energy-saving based on LED street lamps has already broken out. As the further deepening of LED energy-saving effects, there will undoubtedly be another round of industrial storms. However, in the current roads where LED street lamps are being explored nationwide, it is necessary to explore the second energy-saving and intelligent LED control system in combination with the characteristics of LED street lamps themselves. It is understood that the current market application of LED drive power management, LED lighting intelligent energy-saving monitoring solutions can be described as rare. Shenzhen Maoshuo Power Company, which knows this truth, has launched the “Power Carrier Remote Stepless Dimming Solutionâ€. The power carrier technology can adjust the working brightness or on/off status of the LED according to the change of the external environment. This technology can save the trouble of laying a proprietary line and solve the problem of long-distance transmission. It is very suitable for remote control and management of LED street lights. New intelligent solutions promote industry development The “one-time energy-saving†effect of LED street lights is obvious to all. The “secondary energy saving†of intelligent driving of street lights is more important. At present, the reliability of high-power LED street lamps in China generally faces two major problems: one is the reliability and life of the drive power; the other is the rapid heat conduction problem of the heat dissipation system. The instability of the driving power quality has greatly restricted the development of China's LED lighting industry. The rapid rise of Moso Power in recent years has completely solved the troubles caused by the instability of LED drive power for street lamp manufacturers and engineering customers. The high energy-saving effect of Maoshuo intelligent drive power brand will promote the healthy development of LED lighting industry more effectively. According to reports, the new power carrier multi-channel LED power intelligent control system around the realization of energy-saving, environmental protection, multi-function, high reliability and intelligent management and other goals, increased the development of "power carrier intelligent control" function. Its innovative features are mainly: direct use of existing power lines in traditional power supplies, advanced digital signal processing (DSP) technology and BPSK carrier signal modulation with high anti-interference suppression and long communication distance; development and provision of IP Network or GPRS network remote control and intelligent feedback LED street light on/off, dimming, voltage/current feedback, status inquiry, timing control, fault alarm and other working status, operating data and realization of LED light partitioning, sub-line, group management and other functions To achieve further power saving and extend the life of the lamp. Power carrier LED power supply block diagram Speaking of the power carrier LED power supply features, the elements are reflected in: (1) Highly reliable LED street light power supply: It consists of constant voltage/constant current drive module. The constant voltage part of the circuit parameters are: output voltage 12 ~ 48V; constant current circuit design parameters are: output current accuracy ± 3 %; 0mA ~ 350mA adjustable. Design multiple protection functions such as output short circuit, overcurrent/overvoltage, overheating, etc. (2) Signal detection module: The voltage and current of the LED lamp are amplified and rectified, sent to the analog-digital collector, analyzed and compared by the central processor, converted into corresponding voltage/current values, sent to the power carrier module, and transmitted back to the monitoring center. To determine the voltage, current and fault status of the LED light. (3) Power carrier communication function: directly use the existing AC/DC power line as the communication medium, without laying a dedicated communication control line. LED lights can be partitioned, divided into lines, and group management. According to the needs, set the control time according to the working day, holidays, seasons, etc.; online real-time remote operation, dealing with unexpected situations such as sudden changes in weather and accidents. According to the need, automatically adjust the brightness of the LED light by time and place, save energy and extend the life of the LED light. The lamp is automatically alarmed for easy maintenance and guarantees the lighting rate. On-demand remote parameter settings for easy management and improved efficiency. Remote control via IP network or GPRS network. (4) Expanding function: use visible light as the on/off and brightness adjustment of LED street light; data acquisition: such as temperature, humidity, power factor, etc.; monitor power supply temperature: temperature is too high, automatically reduce current or turn off LED light; Required to use, can be reserved. Such an advantage is particularly hot in the process of the “Ten Cities and Ten Thousand Miles†project, which is currently in full swing, and the national semiconductor lighting industry demonstration project jointly promoted by relevant national ministries and commissions. It is understood that the market share of conventional products of Moso Power has exceeded 60%. This new type of product, due to its control for LED street lights, will undoubtedly promote the development of the industry, which is a great event in the industry. Conclusion: The vision of green lighting can't just stay on the advocacy of experts and government officials. Some big companies and big cities should stand up and take the lead in fulfilling their social responsibilities. If they can pay attention to the urbanization of green lighting, they can all notice the importance of intelligent energy-saving monitoring of LED lamps, then everyone's consensus will form a market demand for green lighting. With the demand of the market, green city lighting can be widely applied in the whole society. The rapid development of the industry has provided tremendous development opportunities for all aspects of the LED lighting industry chain, and the technology for driving power supplies is constantly improving. Yongli Tide is the pursuit of Maoshuo Power as always. Meeting the needs of the market and customers, providing the industry-leading high-reliability drive power will be the mission and responsibility of Moso Power. 6-42V Series Electric Compressor Three-phase Sealed Terminal 6-42V Series Electric Compressor Three-Phase Sealed Terminal,Co2 Three-Phase Seal Terminal,Ev Compressor And Hybrid Car Feedthrough,Electric Car Compressor Terminals Shenzhen Capitol Micro-Electronics Co.,LTD , https://www.capitolgtms.com
