The energy-saving renovation of urban street lights is one of the important measures for urban energy conservation and emission reduction. Here are some energy-saving renovation plans for urban street lights:

1. Replacing traditional incandescent or high-pressure sodium lamps with high-efficiency energy-saving LED lamps can significantly reduce energy consumption. LED lighting fixtures have advantages such as high efficiency, low energy consumption, long lifespan, and environmental friendliness. At the same time, they can provide multiple color temperature options to meet different lighting needs.

2. Intelligent control: By installing an intelligent control system, the brightness and on/off time of street lamps can be automatically adjusted according to actual needs, avoiding excessive lighting and waste. At the same time, the intelligent control system can also monitor the operation status of street lamps in real time, detect faults in a timely manner, and carry out repairs to ensure the normal operation of street lamps.

3. Solar power supply: Using solar photovoltaic technology to provide electricity for street lamps can reduce dependence on traditional electricity, lower energy consumption and operating costs. Meanwhile, solar power supply can also reduce carbon dioxide emissions and be environmentally friendly.

4. Cable optimization: Optimizing the design of cables to reduce their length and specifications can lower energy loss and operating costs. At the same time, the use of advanced cable materials and manufacturing processes can improve the conductivity and service life of cables.

5. Regular maintenance: Regular maintenance and upkeep of streetlights can ensure their normal operation and service life. At the same time, timely replacement of damaged light bulbs and components can avoid energy waste caused by malfunctions.

6. Publicity and education: Strengthen publicity and education, raise citizens' awareness of energy conservation, and let them understand the importance and necessity of energy-saving renovation of urban street lights. At the same time, encourage citizens to actively participate in energy-saving actions and jointly create an energy-saving and environmentally friendly urban atmosphere.

The energy-saving renovation of urban street lights needs to start from multiple aspects, including replacing high-efficiency energy-saving lamps, intelligent control, solar power supply, cable optimization, regular maintenance, and publicity and education. Through the implementation of these measures, the energy consumption and operating costs of urban streetlights can be reduced, energy utilization efficiency can be improved, and contributions can be made to the sustainable development of cities.
