Question 1

What are the advantages of solar sensor street light?

Accepted Answer

Energy saving and on-demand lighting: Radar/infrared induction is used to realize "lights on when people/vehicles come and lights off when people/vehicles leave", and the brightness of lamps can be adjusted according to actual needs, with a typical energy saving range of 40%-60%.

Green and low-carbon: photovoltaic power generation during the day and energy storage power supply at nite, reducing dependence on fossil energy; reducing carbon dioxide emissions from the power grid mainly based on thermal power.

Installation and operation and maintenance are more economical: no need to lay cables or excavate roads, modular "pole-mounted and ready to use", greatly shortening the construction period and reducing the overall cost; the system has light control/time control/overcharge and overdischarge protection, etc., the daily maintenance workload is small, and the long-term operation and maintenance costs are lower.

Safety and reliability: 12–24V low-voltage DC power supply is adopted, with low risk of electric shock and fire; the whole machine can reach IP65 waterproof and dustproof level, and the working temperature range is about -30℃ to 50℃, which is more stable in extreme weather such as typhoon, rainstorm, sandstorm and high temperature.

Intelligent management and long life: It can be connected to the Internet of Things platform for remote monitoring and fault alarm; the life of the lamps is usually ≥100,000 hours, and the induction dimming is used to further slow down the light decay and extend the life of the system.

Question 2

What locations are suitable for solar street lights with motion sensors?

Accepted Answer

Solar sensor street light, due to their flexibility and energy-saving characteristics, are very suitable for the following scenarios:

Urban roads and side roads: Automatically adjust brightness according to traffic density, ensuring safety while achieving efficient energy saving.

Parks, residential areas, and rural roads: In these areas, pedestrian traffic is sparse late at night. The "lights on when people are present, lights off when people leave" mode meets basic lighting needs while greatly saving energy.

Remote and off-grid areas: Solar power combined with intelligent control completely solves the wiring problem, providing a safe and economical lighting solution for areas with weak power infrastructure.

In the future, with the development of the Internet of Things and artificial intelligence technology, the intelligent control of individual street lights will be further integrated into the management network of smart cities. Through big data analysis, the system can learn the patterns of pedestrian and vehicle flow in different areas and at different times, enabling more refined lighting strategy scheduling, further improving urban energy utilization efficiency and public service levels.
