At the same time, Zhonglong also participated in the construction of tunnel lighting projects in Shanghai, Fujian, Guangdong, Guangxi, Gansu, Shaanxi, Shanxi, Guizhou and other provinces and cities. Among them, the Shanghai Yangtze River Tunnel is 8.9 kilometers in length and is the largest tunnel project in the world for LED lighting. At present, the company's main products are: LED tunnel lights, LED ceiling lights, LED street lights and so on. Zhonglong LED Tunnel Light is a high-tech product developed by our company for many years. It is also the earliest LED tunnel lighting fixture successfully used in tunnel physical engineering. Zhonglong LED tunnel light uses high-power white LED as the light source. Compared with traditional lamps, it has high color rendering, energy saving and long life. It is an environmentally friendly and energy-saving green lighting fixture. It is the most widely used and reliable in its class and has always maintained its leading edge in technology. Zhonglong Company aims to build a first-class brand based on the needs of the industry, surpass itself and innovate constantly, and strive to contribute to the world's environmentally-friendly and energy-saving lighting.

November 2006: Zhonglong LED tunnel light was applied to Caijiaguan Tunnel of Guizhou Kaikai Highway, becoming the first tunnel lighting project in China to design lamp layout, power and optics according to the parameters of LED tunnel lights. December 2007: Zhonglong LED tunnel light is applied to the Linhezhong Road Tunnel in Guangzhou. It is the first application case of LED tunnel lights in urban tunnels. December 2007: Zhonglong LED tunnel light was applied to the Shanghai Yangtze River Tunnel Project. The LED tunnel light was first applied to the special long river tunnel. December 2007: Zhonglong LED tunnel light is applied to Wulongshan Tunnel of Zhensheng Expressway in Guizhou. The total length of single hole is 6.4 kilometers and 1639 sets of LED tunnel lights are installed. It is the first application case of LED tunnel light in expressway tunnel. May 2008: Zhonglong signed a contract with Guangdong Zhaoxin Enterprise Group Co., Ltd. The cooperation between the two parties is a win-win cooperation with complementary advantages and strong advantages, which will fully reflect the system resource advantages brought by industrial integration. October 2008: Zhonglong LED tunnel light was successfully applied to Caoyuan Tunnel of Fujian Quansan Expressway May 2009: Zhonglong LED street light and LED tunnel light successfully applied to Linjiang Avenue, Zhujiang New Town May 2009: Zhonglong LED tunnel light was approved by Shanghai Yangtze River Tunnel Bridge Project. Zhonglong LED Tunnel Light illuminates Shanghai Yangtze River Tunnel August 2009: Zhonglong successfully won the bid for LED lighting project of Shanghai Renmin Road Cross-river Tunnel August 2009: Zhonglong LED Tunnel Light Successfully Applied to Pingding Expressway Tunnel in Gansu September 2009: Zhonglong LED tunnel light was successfully applied to the Wufoshan Tunnel of Shanxi Jinyang Expressway October 2009: Zhonglong successfully won the bid for the LED lighting project of Guangzhou Metro Parking Lot November 2009: Zhonglong LED tunnel light was successfully applied to Guizhou Huanghuang Expressway Huangguoshu Tunnel December 2009: Zhonglong LED tunnel light was successfully applied to the Tanjiaba Tunnel of Hubei Hurongxi Expressway January 2010: Large-scale replacement of Guangshen Expressway toll station for Zhonglong LED ceiling light April 2010: Guangxi Guanghe Expressway's entire tunnel uses Zhonglong LED tunnel lights April 2010: Zhonglong LED Tunnel Light Successfully Applied to Guangyu Expressway Tunnel Micro inverter is a small inverter used in solar power generation systems, its main function is to convert the direct current generated by a single Solar Panel into alternating current. Unlike traditional centralized inverters, microinverters are usually equipped with one per solar panel, that is, each solar panel has an independent microinverter. grid tie micro inverter, off grid solar micro inverter, hoymiles microinverter price, micro inverter solar system, solar system with micro inverters Ningbo Autrends International Trade Co., Ltd. , https://www.aitsolarpanels.com
Main effect:
1. Individual control: The microinverter provides independent conversion control for each solar panel, which means that each solar panel can optimize its power output individually. This maximizes the power generation efficiency of the solar panels since shading or other influences only affect the power generation efficiency of individual panels, not the entire array.
2. Reliability: Since each solar panel is equipped with a micro-inverter, even if one of the inverters fails, the other panels can still work normally, thereby improving the reliability of the entire system.
3. Flexible installation: Micro-inverters are usually small and can be installed near solar panels without being concentrated in one location, so installation is more flexible and convenient.
Differences from other inverters:
1. Individual control: Compared with traditional centralized inverters, microinverters provide independent conversion control for each solar panel, enabling each panel to reach its maximum power output.
2. Fault isolation: The micro-inverter has the function of fault isolation. Even if one of the inverters fails, other panels can continue to work without affecting the operation of the entire system.
3. Installation method: The micro-inverter can be flexibly installed near the solar panel, and does not need to be concentrated in one location, so the installation is more flexible and convenient.
4. Applicable scale: micro-inverters are usually used in small-scale solar power generation systems, while traditional centralized inverters are suitable for larger-scale photovoltaic power plants.
Overall, the main role of microinverters is to individually control and optimize the power generation efficiency of solar panels and improve the reliability of the system. Compared with traditional centralized inverters, it has some advantages in terms of flexibility, fault isolation and applicable scale.
