Huawei has debuted its Connected City Lighting Solution, an Internet of Things (IoT) lighting solution with multi-level intelligent control. Huawei Connected City Lighting Solution connects street lamps to the IoT and adopts a GIS-based management system, enabling cities to enhance the control and performance of every street lamp. The solution provides municipal managers with status information on each lamp, in every street and enables precise control of on-off switches and brightness of individual street lamps, allowing on-demand lighting and a reduction in energy consumption by up to 80%.

According to The Climate Group, there are approximately 304 million street lamps around the world, and the number is expected to reach 352 million by 2025. Street lamps are almost ubiquitous in cities. While these lamps bring convenience to people's lives, they also consume a vast amount of energy and increase management costs for municipalities. For example, London has approximately 35,000 street lamps, resulting in an estimated total power consumption of 56,000,000kWh per annual, together with inspection costs and maintenance fees, the street lamps significantly impact municipal expenses. Huawei Connected City Lighting Solution is designed to address these issues.

With Huawei’s Connected City Lighting Solution, each street lamp is equipped with a power and brightness controller. Unlike industry-standard access methods such as through Wi-Fi, Huawei adopts 6LoWPAN technology, which has lower power consumption, and can automatically diagnose, network, and trouble-shoot problems, as well as enable better interaction between street lamps and other smart devices such as sensors. To enhance the control and performance of street lamps, the solution integrates a series of preset smart lighting policies to:

  • Automatically calculate lighting duration based on local longitude and latitude, and dynamically adjust lighting duration according to the specific season, month, and day.
  • Smartly adjust brightness by connecting built-in brightness sensors with third-party traffic and people flow sensors, or based on weather and other environment conditions. For instance, automatically reduce street lamp brightness or only switch on every other lamp at midnight when traffic volume is low; or turn lamps on when there is poor visibility such as on rainy days.

Huawei Connected City Lighting Solution pares LED lamps with smart lighting polices. When compared with conventional street lamps, such as high pressure sodium lamps, they help reduce energy consumption by up to 80%.
