lntegrated solar street lights rely on solar energy to be converted into electricity for lighting, but the charging efficiency of solar energy will affect the lighting effect of LED solar street lights. If the charging efficiency of solar energy is slow, it may not reach the lighting time of LED solar street lights at night. The charging efficiency of LED solar street light mainly includes two aspects, namely, the conversion efficiency of solar panel and the secondary conversion efficiency.
The conversion efficiency of solar panels refers to the efficiency of converting light energy into electricity. The secondary conversion efficiency refers to the efficiency with which light energy is stored in the battery after being converted into electricity. In order to improve the secondary charging efficiency of solar street lighting, the capacity of batteries in the current configuration process of solar LED street lamps is generally 1.2 times the power of the solar street light system to meet the demand for night lighting. Moreover, in order to ensure the service life of led solar street light controller, the whole control circuit should also play a protective role in the charging process of LED solar street light.
The solar panels are angled horizontally, so it is crucial to adjust the Angle of the panels for different latitudes and different roads. The solar panels are kept indoors for charging, so you can put the solar lights in the parking shed for nighttime parking, but you also put the solar panels in the shed. In the current solar street light configuration process, the capacity of the battery is generally 1.2 times the power of the solar street light system to meet the demand for night lighting. In the solar street lamp charging process should also play a protective role in the whole control circuit. In terms of the rapid development of current road lighting, only by improving the secondary conversion rate of solar street lights in the daytime charging process can the rapid development of solar street lightss in the future application process be realized.
At present, some solar street lights are constant current charging, which refers to the way of charging by adjusting the output of the charging device or changing the resistance in series with the battery to keep the charging current constant. Compared with constant voltage charging, the control method of constant current charging is much simpler, but because the capacity of the battery to accept current in the process of continuous charging will be less and less, resulting in the later current will be used for electrolytic water, and produce gas. Stage charging is a combination of constant voltage and cross-current charging mode, cross-current charging to the predetermined battery voltage, and then change to constant voltage to continue charging, and finally close to full when it is converted into floating charge to complete the battery final charging process.
In order to better achieve the led solar street light in what is now the rapid development of road lighting, for now the solar street light technology development, only to improve the led solar street light during the day, secondary conversion can be realized in the process of charging the led solar street light in the future application in the process of rapid development, in order to achieve good lighting effect.
