ELECTRONICS 2 TECH FULLY AUTOMATIC EMERGENCY LIGHT Circuit Diagram In this circuit (12-0-12V) step down transformer is utilized as the fluorescent driver transformer that is the primary winding terminal is connected to the 20 watts fluorescent light and secondary (12-0-12V) center tapped terminals are connected with switching pulse circuit. Here VR1 variable resistor and C1 capacitor is responsible for switching pulse that is applied to the switching power

Besides, you also get an opportunity to customize the circuit as per your own requirements. The idea of the present emergency light circuit is that it should be compact and may be kept plugged into the mains socket for a permanent automatic operation. The light can also be charged through a solar panel when the mains is not available for a long 4.The circuit should have low voltage cutoff while discharging and high voltage cutoff while charging(I think tp4056 has high voltage cutoff feature) Good backup 5.circuit should be powered with 5v mobile charger. If there is cheaper and efficient circuit than tp4056 for charging above cells in the ckt plz tell .

DIY Emergency Lights: 10 Circuit Ideas Circuit Diagram
We have described the design of an Automatic emergency LED light circuit in the above discussion. We have also defined the use and working of LDR (Light-emitting resistor) in detail. We hope you have got a good knowledge of LDR working principle that will help you to understand the working of LDR in our Automatic LED emergency light circuit. 3) Automatic Emergency Lamp Circuit with Low Battery Cut-off. The following circuit shows how a low voltage cut off circuit can be included in the above design for preventing the battery from getting over discharged. 4) Power Supply Circuit with Emergency Light Application As a result, we've opted to create an "Automatic Rechargeable LED emergency light circuit" in this tutorial. Automatic Emergency lighting is a simple setup circuit that may be completed quickly. The Emergency Light circuit's components are readily available and affordable. When it comes to energy saving, it's good to use that.

Application of Automatic Emergency Light Circuit. An automatic Emergency Light Circuit could be used in places where the light gets on automatically as the power goes off. It could be used as an emergency lamp in homes and other places. It could be used in study rooms and workplaces in order to avoid sudden power failures. An automatic Working of Automatic Emergency Light Circuit. Initially, when the mains power is active, the battery charging circuit will charge the battery. In case the mains power is shut down, the battery charger circuit indicates the Emergency Light circuit about mains power and activates the emergency lights circuits through the battery.
