Working principle of the solar street light controller is introduced

1, solar panels, solar panels is when the sun is used to convert solar energy into electrical energy, it according to the power of the power capacity of the lighting and lighting to common computing time. Such as lighting lamps and lanterns is 2 watts, and also requires that in the absence of Yang

1, solar panels solar panels is when the sun is used to convert solar energy into electrical energy, it according to the power of the power capacity of the lighting and lighting to common computing time. If the work is 2 watts lighting lamps and lanterns, and also requires without sunlight to 10 hours continuous lighting time, to consider the conversion loss of transform circuit, the power of solar panels must is about 3 watts.

2.

battery storage battery is the function of the electricity stored solar energy battery, for without the use of the sun, the capacity of the battery according to the power of the power of solar panels, LED lights and lighting time to decide. Such as cooperate with 2 watts of LED lights, 3 watts of solar panels, there is no sun, 10 hours continuous lighting time, can choose the 12 v / 2. 2 ah battery.

3, solar charge control circuit is the function of this part of the circuit in sunny, illumination time long time control degree of charging, the battery is to stop charging, don't make the battery overcharge and cause damage, to protect battery and prolong its service life.

4, LED drive

this is the core of the system control circuit, its function has three:

a, complete the LED constant current drive control, current through the light tube make no changes over battery voltage;

b, with optical function, at daybreak automatically turn off the lights, turn on light automatically when it gets dark;

c, low voltage protection. When the battery voltage drops to 10. 8 volts output shut down, in order to avoid battery over discharge damage.
