LED intelligent lighting has become a key node in urban development
A century ago, only 10% of the population on Earth lived in cities. In the early 21st century, this proportion increased to 50%. Scientists predict that by 2050, two-thirds of the population will live in cities.
Studies have shown that urban energy consumption accounts for 70% of global energy consumption, and this proportion will continue to increase. With the unpredictable urbanization process and the rapidly expanding middle class, humans need to face increasing problems: energy shortages, excessive greenhouse gas emissions, threats to biodiversity, and food and water stress. How to meet the ever-increasing energy needs of mankind without avoiding damage to the environment has become an important issue facing humanity.
At present, humans have made a lot of progress in the research and application of smart and clean energy. For example, in the field of lighting, which accounts for 19% of global energy consumption, LED lighting has become a key node for development.
The data shows that 60% of lighting energy consumption comes from urban commercial buildings and public housing, and 15% comes from street lighting. LED lighting makes it possible to achieve significant energy savings in the lighting sector – replacing LED lamps can reduce energy consumption by 40%, saving 128 billion euros worldwide, equivalent to a reduction of 670 million tons of carbon dioxide emissions. Researchers predict that LED lamps will account for 50% of the lighting market during 2010-2015.
LED lighting can significantly reduce energy consumption and post-maintenance costs, especially when LED lighting is combined with intelligent lighting control systems. The intelligent lighting control system creatively combines LED luminaires, control switches and Internet programs to provide the right lighting illumination at the right time, further reducing energy usage and luminaire wear and providing safe, comfortable lighting for humans. Experience.
With the increasing number of urban populations, static and passive street lighting systems that are widely used today are increasingly unable to meet the needs of cities. Livable cities need street lighting to be adjusted at any time based on changes in traffic and urban activities.
As an innovative, holistic urban outdoor lighting solution, a smart outdoor lighting management system called “Touch City†came into being. The “Touch City†system provides cities with innovative, intelligent and flexible lighting solutions. Combined with LED-based lighting materials, the system can save up to 70% on lighting and management costs.
The “Touch City†system allows users to control the outdoor lighting system throughout the city through an Internet interoperability program. The program provides usage of every street lamp in the city, including brightness and loss data, and provides easy-to-use control and maintenance solutions. For example, in the period when the traffic volume is low, the program can automatically reduce the brightness of the illumination; the program automatically detects the damage of the street lamp and generates a maintenance report.
At present, the Argentine capital of Buenos Aires is applying LED intelligent lighting control technology to update the urban street lighting system. In the past three years, the city's 125,000 street lights will be replaced with smart LED lamps. LED intelligent lighting control system can provide 5 times the service life of traditional lighting fixtures for the city street lighting system, saving 50% energy consumption and significantly reducing urban carbon dioxide emissions.
