The working principle of the solar LED lighting circuit is as follows:
the solar cell panel input module 1 adopts a solar cell panel with the voltage of 5V, and can directly charge the battery 2. In the morning, the voltage of the solar cell panel is gradually reduced from zero to 5V, in the evening, the voltage of the solar cell panel is gradually reduced from 5V to zero, and the stronger the sunlight is, the larger the output current of the solar cell panel is.
When the solar panel is bright in the morning, the solar panel starts to output voltage, when the output voltage is higher than the voltage of the battery 2 and the forward voltage of the diode D1, the battery 2 starts to be charged, and the charging current is increased along with the increase of illumination. In the evening, the charging current is reduced along with the reduction of the illumination, and when the output voltage of the solar panel is lower than the voltage of the battery 2 plus the forward voltage of the diode D1, the solar panel stops charging the battery 2.
When the intensity and time of day illumination are enough, the battery 2 is charged fully and then disconnected, and charging is stopped.
When the solar panel is illuminated in the daytime, the output current of the solar panel flows through the resistor R1 to the base electrode of the triode V1, and flows through the diode D1 and the resistor R2 to the collector electrode of the triode V1, at the moment, the triode V1 is conducted, the triode V2 is not conducted, the field effect transistor Q1 is not conducted, and the battery 2 cannot discharge through the field effect transistor Q1.
When no illumination is available at night, the solar panel does not output voltage, the base of the triode V1 does not have voltage current, the triode V1 is not conducted, the solar panel does not output voltage, the output current of the battery 2 passes through the base of the triode V2 through the resistor R2, the output current of the battery 2 passes through the collector of the triode V3 to the collector of the triode V2, the triode V2 is conducted, the grid voltage ratio of the field-effect tube Q1 is extremely high, the field-effect tube Q1 is a P-type MOS tube, the field-effect tube Q1 is conducted, the positive current of the battery 2 passes through the field-effect tube Q1, the LED lamp bead, the resistor R10 (or the resistor R11), the resistor R12 (or the field-effect tube Q2) to the negative electrode of the battery 2, the LED lamp bead has current flowing through, and the LED lamp bead is lightened. When there is illumination next day, 2 boards of solar cell when having output voltage, battery 2 stops discharging, perhaps 2 electric quantities of battery exhaust, and LED lamp pearl just can go out.
When someone enters the sensing region, the Vout pin (i.e., the fourth pin) of the chip IC outputs a voltage, which is transmitted to the gate of the fet Q2 through the resistor R5, and the fet Q2 is turned on, thereby shorting the resistor R12. When the battery 2 is in a discharging state at night, if no person enters the induction area, the discharging current-limiting resistor Rs1 of the battery 2 is formed by connecting resistors R10 and R11 in parallel and then connecting the resistors with R12 in series, if a person enters the induction area, the discharging current-limiting resistor of the battery 2 is formed by connecting resistors R10 and R11 in parallel and then connecting the resistors with the on-resistance of the field-effect tube Q2 in series, two different discharging current-limiting resistors exist, two different LED currents exist, and the LED lamp bead can have two different brightnesses. Generally, the resistance of the resistor R12 is far greater than the on-resistance of the resistor R10, the resistor R11 or the field effect transistor Q2, so that when someone enters the induction zone, the brightness of the LED lamp bead is brighter, and when nobody enters the induction zone, the brightness of the LED lamp bead is darker, so that the electric quantity of the battery 2 can be saved, the discharge time of the battery 2 is prolonged, and the whole night LED lamp bead can work.
The LED output module 5 is formed by connecting a plurality of LED lamp beads in parallel, and the number of the LED lamp beads can be determined according to actual brightness requirements.
The capacitor C1 is used for supplying power to the chip IC, the resistor R6 and the resistor R7 are used for setting the delay response time of the chip IC, the resistor R8 and the resistor R9 are used for setting the infrared induction sensitivity of the chip IC, and the capacitors C2 and C3 play a role in filtering.
This circuit mainly utilizes daytime when having illumination, and solar cell panel charges for battery 2, and when no illumination evening, battery 2 discharges and gives LED lamp pearl. The reasonable resistance that sets up resistance R10 (the resistance value is 2 omega), resistance R11 (the resistance value is 2 omega) and resistance R12 (the resistance value is 150 omega), realize that LED lamp pearl is brighter when someone passes through and unmanned LED lamp pearl these two kinds of different luminance darker when passing through, the discharge time of extension battery 2 ensures that whole night LED lamp pearl can both work.
