The circuit is basically made up of a single pnp.
The diode d2 prevents the battery charge from flowing back it acts as a free wheeling diode too.
The emergency lighting fixture is composed of a light source a light source driver a rectifier an inverter a battery pack a logo lamp housing something like that.
The transformer bridge and the capacitor forms a standard power supply for the circuit.
If you have any doubts.
The automatic emergency led light circuit can be designed in two parts.
Automatic emergency led light circuit diagram.
The step down transformer and the diode bridge rectifier steps down and convert the high ac in the range of 110v or 230v voltage to low 12v dc voltage.
Here is a circuit diagram of an emergency lighting made with les.
First part is used to drop down the 220v ac voltage into 8v regulated dc with the help of transformer and bridge rectifier.
