Shu, your question is very confusing. It's filed under Laser Pointer, but titled Emergency light, then you're talking about a 6 volt battery being shorted to 220 VAC.
I can't make any sense out of any of that, so let's start at the beginning.
First of all, what exactly is it you're trying to fix? Manufacturer and model number is usually the best information to use. Including a picture is always helpful
Next, describe what the problem is in detail. Tell us what the device is or isn't doing, how it started and anything that may have happened to the device that could have cause the problem.
That's how to ask a good question and get an answer. Your question as it is is unanswerable and unlikely to get any useful responses.
