Smart Street Lighting Project In Lasi,Romania

This project is to intelligently transform street lights in the suburbs of LASI. Some of the street lights in LASI were traditional HID, with power mostly 250W and above; some of the street lights were LED street lights that had been installed for many years, with low light efficiency and difficult to monitor, requiring manual on-site inspection. It not only wastes energy, but also wastes a lot of manpower and material resources. In the early stage of the project, more than 8,000 sets of smart street lights have been installed, adopting smart energy-saving mode and setting automatic dimming to reduce power at night. Reduce street light power consumption by more than 50%.

CHZ cooperated with Zhejiang Fangda Intelligent Control Co., Ltd., a well-known intelligent lighting controller supplier in China, and launched CHZ LIGHTING intelligent lighting street lamps based on its own product characteristics. The street lamps use the latest 4G interconnection technology to turn individual street lamps into The interconnected street light groups then use a centralized controller to upload the signal to the cloud. The owner can know the status of each set of street lights through the server and mobile terminal and perform dimming control. According to different city requirements and different environments, GPRS/4G solutions and LORA solutions can be customized.

This project is to intelligently transform street lights in the suburbs of Iasi. Some of the street lights in Iasi were traditional HID, with power mostly 250W and above; some of the street lights were LED street lights that had been installed for many years, with low light efficiency and difficult to monitor, requiring manual on-site inspection. It not only wastes energy, but also wastes a lot of manpower and material resources.

The picture below is a street light scene modified with our ST29 smart street light. The street lights are all installed on cement pillars, with a height of about 8m, an arm length of about 1.2m, and power levels of 30W, 40W and 50W.

Our street lights all use the highest brightness SMD5050 light source and specially customized lenses, which make the light efficient and uniform. Judging from the test results, for an 8-meter-high light pole, using 30W power, the average ground illumination reaches 25LX; using 40W power, it reaches 31LX; and using 50W power, it reaches 38LX. The uniformity has reached 0.6, fully meeting or exceeding the standards required by the municipal department. The street lighting throughout the town greatly facilitates the travel of local people; although there is a lot of snow on the ground, passing vehicles are still flowing smoothly and everyone feels very safe, which means that the light color is very comfortable and bright.

Street light intelligent control demonstration:

The customer conducted a street light intelligent control demonstration through the Fangda intelligent system installed on the IPAD.

First of all, this system can clearly display the location, quantity and status of the installed smart street lights. It is very clear. Each set of street lights has a number and can be controlled centrally or individually. Then, we conducted a dimming test and adjusted the brightness of the street lights (50W) on this road from 100% to 80%, 70%, 60%... 20%, 10%. The brightness on the road immediately It got dark.

  When the power is reduced to 10%, the maximum illumination of the street light still reaches 6.5LX; when there are few vehicles late at night, there is still no problem with safe driving of the vehicle.

In the early stage of the project, more than 8,000 sets of smart street lights have been installed, reducing the power consumption of street lights by more than 50%. At the same time, intelligent energy-saving mode is adopted, and automatic dimming is set at night to reduce power. In this way, the total lighting power consumption is reduced by more than 80% compared with previous years. Both the general public and municipal management departments are very satisfied with the quality and lighting effects of our smart street lights. It can be seen how important intelligent control is for energy saving in road lighting.
