When the power fails the white led s which are connected mosfet will glow based on the light condition till the battery shuts down. Once the power is restored back to this emergency rechargeable light circuit t2 is switched off the battery starts charging and the cycle repeats. A very simple automatic solar light system ca be built using some leds a rechargeable led emergency light circuit with battery over charge. The rechargeable battery is a small sealed lead acid sla battery 4v 500mah. The charger power supply section is built around. When ldr light dependent resistor is in light the resistance of ldr is very low. When the battery is fully charge charging stops automatically. While charging diode d5 pulls the base of the led driver transistor t1 down to turn off the light source led2. The light turns on automatically when mains supply fails and turns off when mains power resumes. Automatic emergency light circuit principle when power supply is available battery charges through the battery charging circuit.
This happens because the minimum forward voltage required to light up white leds is around 3 5 volts plus series voltage drop.
The charger power supply section is built around. A very simple automatic solar light system ca be built using some leds a rechargeable led emergency light circuit with battery over charge. The second part of the emergency light circuit consist the main functionality that is to automatically switch on the emergency light array of white leds on power failure. The charger power supply section is built around. Once the power is restored back to this emergency rechargeable light circuit t2 is switched off the battery starts charging and the cycle repeats. When the power fails the white led s which are connected mosfet will glow based on the light condition till the battery shuts down.
When ldr light dependent resistor is in light the resistance of ldr is very low. When the battery is fully charge charging stops automatically. However when power. Note that in a common capacitive power supply there s a zener diode to limit its output voltage whereas this circuit just uses the sla battery to provide a low impedance clamp. The second part of the emergency light circuit consist the main functionality that is to automatically switch on the emergency light array of white leds on power failure. This happens because the minimum forward voltage required to light up white leds is around 3 5 volts plus series voltage drop. Once the power is restored back to this emergency rechargeable light circuit t2 is switched off the battery starts charging and the cycle repeats. We have used relay here to automate this.

The light turns on automatically when mains supply fails and turns off when mains power resumes. A 6v 4 5ah rechargeable battery is connected to the array of leds through a relay. When the battery is fully charge charging stops automatically. The rechargeable battery is a small sealed lead acid sla battery 4v 500mah. Once the power is restored back to this emergency rechargeable light circuit t2 is switched off the battery starts charging and the cycle repeats. It has its own battery charger.
