How to repair old torch or emergency Light?

Repairing of emergency lights or torch is very clean in recent times. If you’ve got dome fundamental repairing components then repairing isn’t always a tough venture. In this newsletter, I will show you little by little checking technique from wherein you could easily locate which components/ issue is misbehaving.

What is the hassle of my emergency light?

In my emergency mild, there are few problems
1st: the switch of the light is jammed. Light on and off system takes too much effort.
Second: In spite of being charged the light the mild is going for walks very Short duration.

Steps need to be observed for checking the emergency light.

Step1: first open the torch or emergency light with screwdrivers.

Step2: There you’ll discover three predominant additives

Light Module itself.
Battery
Charging Board.

We will take a look at all the additives one at a time. For a greater clean concept, you have to watch the YouTube video.

Step3: first we ought to charge the emergency mild with given adaptor or energy cable for about 3 hours. Now if the battery is OK then it’ll deliver power to the mild but if it is not OK then the light will run for a brief time and then we are able to take into account that the battery is lifeless.

Step4: Now you have checked that the battery can’t capable of keep the rate then truly exchange the battery otherwise you have to follow the step5.

Step5: you’ve got checked the battery voltage is almost the mentioned voltage (i.E. For some cases 4v and some cases 6v) then the hassle need to be from the charging board or the light phase.
First, have a look at the components on PCP see that if there may be any burning mark then you definitely have to test it at the primary sight.
Your second paintings might be to smell the PCB and you have to find if there’s any burnt odor.
Ok, That became the clean element.
Now you have got to check all components component by way of part.

Step 6: First see the AC Capacitor is OK or now not if the AC Capacitor (PF) is looking just like the blasted mode or if there’s any mark of a reduce then you must understand that PF isn’t working.
Now we can take a look at the Bridge rectifiers.

(i.E. If you do not know how to test the diodes here’s a short demo for you. Set your millimeter to diode mode then use the two props of the muleteer multimeter to the diode. Community connect the two props to the diodes end and do the equal component through replacing the 2 quit of the diode. In case you see that value is displaying only one course then you definitely have to keep in mind that the diode is OK if you face any such situation where you are gating values for the two aspects. Then you definately ought to keep in mind that the diode is damaged.)

Generally, the resistor related with the parallel to the AC Capacitor damage. Other resistors which are auxiliary they have to not damage commonly.

Step7: Now until this step every element are OK. All are operating belongings. Now the following element you’ll look first is the switch itself. I’m my case the transfer was completely jammed. As a end result, the light changed into not working nicely.
So, what I did is that I used coconut oil for clean motion of the transfer. And It labored simply quality.

Step8: think such a scenario where you have checked all 7 steps noted before. And your light changed into no longer cured.
So right here the troubles have to be the spot lights itself.
It now and again happens… You have forgotten to turn off the light when the light is charging. If this occurs in your light then you need to get rid of the bad LED and replace it with a good one.
Conclusion:
So, those are the major troubles came about in Emergency LED light. If you locate this subject matter useful to you have then please proportion this text along with your family, Neighbors, circle of relatives, and everywhere the sector.
