How to use electric car storage battery and energy saving lamp to produce street lamp
The power supply voltage of the LED can be easily limited below 15V
It is the most energy saving scheme to make lighting lamp with LED LED. The working voltage of LED is low, and the battery power requirement is attached
The most important point of using LED is that the supply voltage is stable, and the slightly higher voltage can cause LED damage.
Battery car battery series voltage, battery voltage and battery charge used vary greatly, in order to make the power supply voltage regulator circuit lamp will not be too complicated, so to the battery lighting device power supply voltage should not be too high, with a 12V battery to supply it.
