Accurate to minute time division full coverage
Establishing an organic unified design, construction, and management energy conservation supervision system, and conducting pre-assessment and review of energy conservation for road lighting construction projects is a very effective energy-saving method. Currently, relevant departments are reporting to the municipal government for approval. The relevant person in charge of the Urban Management Bureau said.
The main secondary roads in the central city are also good energy-saving means according to the lighting needs of different time periods. The person in charge said that Chengdu divides roads into five categories: express roads, main roads, secondary roads, feeder roads and residential roads. At present, the illumination of various roads has been distinguished. We will also adjust the illumination of the same road according to the amount of traffic and the time of the traffic. The person in charge said that this work requires a pilot promotion process.
At present, the coverage of Chengdu streetlight centralized monitoring system has reached more than 80%. If the centralized control is fully covered, the central city will turn on the lights for 1 minute, which will save about 319 degrees.
Multi-test new technology to adhere to energy-saving pilot
At the beginning of this year, the relevant departments began to clean the lampshade and reflector to ensure the light transmission effect. Mainly the lampshades and reflectors of the main and secondary roads, they will be cleaned regularly and strive for once a year. The person in charge said.
Actively explore the application prospects of new technologies and new products with high energy, low consumption and long life in road lighting, and insist on piloting energy conservation. The person in charge said that Chengdu has been actively testing new light sources and energy savers, but it is not very satisfactory at present.
According to reports, in order to actively explore and promote new technologies, new products and new ways in the field of urban road lighting, the Urban Lighting Management Office of Chengdu Urban Management Bureau will prepare for the selection of variable power ballasts and LEDs in accordance with the capital planning of the Municipal Urban Management Bureau in the second half of this year. Energy-saving products such as street lamps and induction lamps are piloted for small-scale installations, laying a solid foundation for further determining the application prospects of road lighting and promoting urban lighting energy conservation.
