This project s design takes advantage of simple circuit techniques and cheap.
Circuit diagram 6v emergency light circuit board.
The diode d2 prevents the battery charge from flowing back it acts as a free wheeling diode too.
Lithium battery 18650.
We carry emergency light circuit boards and exit sign circuit boards for a variety of brands.
This led emergency light circuit can be divided into two parts.
First part is used to drop down the 220v ac voltage into 8v regulated dc with the help of transformer and bridge rectifier.
Referring to the circuit diagram we see that the circuit is actually very easy to understand let s evaluate it with the following points.
Even it shuts down when mains is on.
It has charging line 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 either you buy or make yourself.
And second part consists of relay and rechargeable battery which is used to lighten the leds during power failure.
Call us if you can t find the replacement you are looking for.

I have tried this circuit but when i connect 6v smd led strip to the bd 140 collector terminal and ground the led was dimming very low as low as not glowing and i was measure the voltage respect to battery negative pole on emitter of bd 140 is shown 6 8 v but on collector is 4 3v.
Here is a circuit diagram of an emergency lighting made with les.
