Urbanization has increased the number of street lights in urban road lighting year by year. However, the constantly optimized night lighting system greatly enhances the night driving vision and beautifies the city night scene, but it hides huge energy consumption and extremely high street lamp maintenance. cost. On the one hand, traditional high-pressure sodium lamp street lamps occupy and consume 40% of the city’s public electricity consumption. The huge pressure on electricity costs and the social environment of energy-saving and emission reduction make outdoor road lighting urgently in need of upgrading; on the other hand, street lamps in cities The deployment of smart cities is everywhere. The construction of smart cities requires the intensive use of street lights to increase the efficiency of use while reducing maintenance costs to improve the efficiency of city management. This has become a topic of common concern for the government and enterprises in recent years.

In order to meet the contemporary demand for smart street lights in smart cities, Osram has developed and launched a DEXAL series drive power supply that complies with the latest D4i certification standard of the DiiA-ZHAGA Alliance. It aims to replace traditional high-pressure sodium lamps with LED street lamps. Add "digital" controllable solutions to create the best energy-saving upgrade solutions for outdoor street lights for cities.

Transform smart street lights to increase efficiency and energy saving for the city

In the construction of smart cities, smart street lights no longer exist solely as public infrastructures. With their geographical advantages widely distributed in the city, they become the natural carrier of sensors and the source of networked information collection in the construction of smart cities in the future. Form a sensor network covering and serving the entire smart city.

A smart city is a new generation of information technology that integrates information such as the Internet of Things, cloud computing, big data, and spatial geography. It is a new concept of intelligence and digitization that promotes the integration of urban planning, construction, management, and services. Under the influence of the widespread application of emerging technologies, traditional street lighting systems are gradually developing in the direction of intelligence and networking. Smart cities use smart street lights as the basis for the distribution of city nodes, and smart street lights provide a data collection basis for the smart city platform. The storage, exchange, and management of data is an important part of the development of smart cities. City managers can add sensors to street lights to collect and collect different types of information to enhance the management of city safety, or build street lights into “smart light poles” to rent to network providers and install 4G/5G base stations to reduce Street lamp maintenance cost.

A key step in building a smart street light system is to transform traditional high-pressure sodium lamps into smart LED street lights. Osram developed and launched the DEXAL? series drive power supply that meets the latest D4i certification standard of the DiiA-ZHAGA Alliance, which provides street light manufacturers with drive power that meets the D4i standard, so that they can complete intelligent upgrades without replacing the entire street light, thereby helping cities accelerate Promote the process of smart city construction.

It is worth mentioning that, with its outstanding performance in the fields of digital lighting, driving, and power supply, Osram's DEXAL? series driving power supply not only won the German Innovation Award 2019 but also a well-known industry media held in China on December 6, 2019. Activity-won the "Annual Driver and Power Brand Award" at the Gaogong LED Annual Conference.
