This view of the current design of solar lighting systems in the existence of a range of issues to study and improve. There are two specific issues, one is the battery charge and issue a release,two is LED lighting's open and closed, and power control issues.
The design can solve the existing these problems, the design of the battery charge of the protection and under-voltage protection, when the battery voltage is too high, the system will automatically stop charging.When voltage value is back to a certain value, once again their charging that. When voltage is too low , the system will automatically cut off the load, so that there were battery-life impact of the phenomenon. When the voltage is back to a certain value, once again connected load. In addition, the LED lights on the control of a very human nature of the design, control mode can be divided into: pure light control, light control + delay the closure, light control + delay after a particular power LED.
This design of the system a better life can be improved and more use of power, to achieve the lowest cost the best lighting effects,further achieve use of green energy to environmental protection purposes.
