The originator of this circuit idea is Mr. Uttam Sadhukha, Howrah. He is a circuit designer, and works for helping hobbyists.
This circuit is for 3in1 emergency light. For loadshadings, we need light as well as a fan in summer. Normal emergency lights comes with tube, torch and blinker, as space required for fan is much. But in circuit design it doesn’t matter.
The circuit describes it all. If you need clarification in some areas, please comment below your questions. All parts that are needed is listed in the schematics itself. The charging require 9-0-9 transformer for quicker charging, but keep in mind that it may overcharge the electrolyte so, switch off mains after full charge,
You can easily separate parts of this total circuit to build a 6V charger, or 6V emergency light, or blinker, etc.

hey thanks for the circuit
please can u the idea or circuit for showing the charging/charged status for the 6v 4.5 Ah battery
THANKS.
Arup says
You can measure the voltage and calculate whether it is charged or not.

hello dear, if i hendel that cirtuit from solar then how i will do that,becoz i want to do a single fan,single emergency light handel from solar sys,plz also tell me about batery,and solar panal for that circuits
Arup says
I'm not getting you. Please explain.

Hello sir,can u please send me the circuit of only emergency light to my email.
mahesh says
Sir,
what is the value of transformers that u have used in this circuit and how much powered motor i have to use for this circuit and how much volt tube i have to use.
