3-Option switch or Pattern change

Option 1 = Full Light
Option 2 = OFF
Option 3 = Normal Light

Backup Time of the Emergency Light lamp.

Battery backup time of the emergency LED light Circuit

Option 1 ( Full light) = 4-6 Hrs.
Option 2 ( Normal Light) 10 Hrs.

Here is the full story that how did i make this post and share with you guys.

Actually, someone bring me a DP-716 Emergency LED Light lamp. So I took the lamp (for checking/repairing).

Here you can see the whole story in images.

Here, we have opened it for repairing. ( You can also try on such your home appliances, but keep in mind that safety is more important….)

Now it is clear that what is the real problem in pic ( two resistor were blown out) so now we want to fix it.

another view. check the circuit that what is the problem here.

Here you can see that what i did in this circuit. because the resistor on the back side ( which i have soldered) was blown out. so the root of problem was that specific resistor.

We have done the job. Now the pattern change switch is on Option 1 i.e. on Full light. the back up time will be 4-6 hours.

And in this case, the pattern change switch is on Option 3 i.e on Full light. the back up time will be 8-10 hours. also note that , option 2 is for turning off the Bulb light.
