Modular design scheme of driving circuit for solar street light

Under normal circumstances, when designing the solar street light drive circuit, the voltage should be checked first. The general use range of direct current is between 9-30V, and if alternating current is used, it is between 84-264V. Both of these voltages are input voltages. Therefore, if you want to make the solar street light work stably, you must have a constant current source, so that the voltage has an accurate constant current input. In this way, each high-power LED light source works under a constant current during operation. This can also reduce the loss and aging of the line. The efficiency of electric conversion is more than 90%, so when designing the drive circuit, there must be a constant current input. Ensure the normal use of the LED light source. The modular design of the solar street light source has various requirements in the current street light project, and there are also different requirements for the solar street light source. In order to better adapt to various road requirements, the light source is modularized. Meet the ratio of road surface, brightness and power. The number of LED light sources can be increased or decreased. To meet the needs of various road widths and illuminances, to achieve the purpose of lighting engineering road surfaces and saving energy. LED modules can be individually designed as 15W 20W 30W 40W 60W etc.
