Yesterday, this year’s typhoon “Tengjiao” made landfall in Guangdong and other areas, reaching a wind level of 10. Branches were broken and traffic was obstructed. In the face of unavoidable natural disasters, road safety has become a significant concern. How can LED solar street lights stand firm against strong winds and heavy rain? Besides reinforcing the base, a reasonable design of the lamp pole configuration is also necessary.
Withstand typhoons and maintain stability. Below, we will discuss the design planning of LED solar street light wind resistance:
1) Angle Planning
To maximize the solar radiation that solar panels receive throughout the year, it is essential to select an appropriate angle for the solar panels.
There has been much discussion in recent years regarding the angle of solar panels in various academic publications. The angle selected for the solar panel bracket is 45 degrees.
2) Wind Resistance Planning
In the solar street light system, a critical aspect to focus on is wind resistance planning. The wind resistance planning can be divided into two main parts: the wind resistance of the solar panel bracket and the lamp pole.
(1) Wind Resistance Planning for Solar Panel Bracket
Based on the technical parameters provided by the panel manufacturers, the maximum wind pressure that solar panels can withstand is 2700Pa. Assuming a wind resistance coefficient of 27m/s (equivalent to a typhoon level 10), according to non-viscous fluid mechanics, the wind pressure on the panels is only 365Pa. Therefore, the panels can easily withstand wind speeds of up to 27m/s without damage. The key consideration in the design is the connection between the panel bracket and the lamp pole.
(2) Wind Resistance Planning for Solar Street Light Lamp Pole
The chosen welding seam width must meet the requirements. As long as the welding quality is ensured, the lamp pole’s wind resistance is beyond doubt.
