Description

Energy-saving street lamp control system and street lamp system using the system

technical field

The utility model relates to the field of mechanical control, in particular to street lamp control.

Background technique

Not only the number of street lamps is huge, but also the power of a single street lamp is large and the lighting time is very long. Street lamps consume a huge amount of electricity in the grid, which brings a huge burden to the grid power supply. In order to reduce the energy consumption of street lamps and reduce the burden on the power grid, some road sections have begun to use LED street lamps, thus achieving a certain energy-saving effect.

In order to further reduce the burden of street lamps on the power grid, solar LED street lamps are used in some road sections. Use solar panels to power LED chips to achieve lighting effects. In the case of relatively sunny weather, the electric energy provided by the solar panel can even provide all the electric energy for the LED chips to illuminate at night. However, in the case of bad weather, such as continuous cloudy and rainy days, the electric energy generated by the solar cells cannot fully meet the electric energy required by the LED chips for nighttime lighting.

In other words, the existing solar LED street lights will still cause a certain load on the power grid. It is necessary to further reduce the load caused by street lamps on the grid.
