Problems solved by technology

[0002] Solar lamps are widely used in garden decoration, road lighting, etc. because they do not need to erect wires or pre-embedded cables, are easy to install, and do not require electricity charges after installation. However, current energy storage solar lamps generally use constant current control In this way, the controller cannot automatically detect the capacity of the battery and automatically adjust the light intensity according to the capacity. When the capacity of the battery is sufficient, it can work normally. No matter how much the battery capacity of the LED lamp is, it works at the rated power, and the power consumed by the LED lamp cannot automatically change with the battery capacity.
In the case of a certain capacity, it is difficult to meet the long-term lighting, and the range of use is affected
The conventional solar LED street light controller adopts constant current source control, its efficiency is about 80%, and its luminous efficiency is low, and because the LED lamp beads work in a constant current state for a long time, the brightness of the LED lamp beads has a large attenuation, which affects the LED lamp bead. The service life of the lamp causes an increase in the cost of use, and lacks market competitiveness in terms of cost performance
