Abstract

The invention relates to a light energy street lamp system in rainy days. The light energy street lamp system comprises a photovoltaic power generation unit, a lighting unit, a detection unit and a control unit, the photovoltaic power generation unit generates electric energy by using sunlight and stores the electric energy; a detection unit is used for detecting a target object on a target road surface in the illumination range and the moving trend and the position of the target object; and current rainfall and visibility are detected. The control unit determines the luminance and color temperature of the lighting unit by calculating the electric energy stored by the light energy street lamp and combining the current rain vigor and visibility, and determines the lighting angle of the lighting unit. Furthermore, the multiple street lamps are controlled to work cooperatively through the energy-saving control method, and the system has the effects of balancing the lighting effect in rainy days and saving energy.

Description

technical field [0001] The invention relates to the field of lighting equipment. Specifically, it relates to a light energy street lamp system in rainy days. Background technique [0002] With the improvement of national environmental protection requirements and public awareness of environmental protection, most social infrastructure projects use energy-saving electrical equipment as much as possible. Among them, as street lighting equipment widely used in urban construction, due to the large amount of use, and it is related to the safety of the road surface and the overall image performance of the road surface, a large number of solutions have been proposed in related fields in terms of balancing lighting effects and energy-saving effects. Especially for areas and road sections where the grid laying is not perfect, in rainy or bad weather conditions, a related solution is needed to provide intelligent and efficient lighting services for local residents. [0003] Refer to ...
