Hey Guys,
Need your help and advice!
I am trying to make an led emergency lighting system. This is completely disconnected from the regular wiring circuit at my house.
I live in India and have been having a few issues with the electricity supply! More demand less supply not enough rains...blah blah blah...!
Either ways..
I wanted to build this..View attachment 67525 (sorry about my paint skills)
I want to be able to control the intensity, know how much juice is left, and turn on/off the panels individually.
I plan to use 5 BL-5C (http://www.cpkb.org/wiki/Nokia_BL-5C_battery ...we get them for cheap here like $4 or 5) in series so that the Voltage is around 18V (3.7V*5) and 5100mAh (1020mAh*5) (hope my math is right!)
I plan to use 36 piranha 4 pin leds (Datasheet: https://www.electro-tech-online.com/custompdfs/2012/09/9263.pdf)
on each panel in a 6x6 configuration. And there are a total of 6 panels (I plan to put each panel in a separate location like at 4 corners and 2 in the middle of my gallery and hall)
now.. here is where i need help and advice from you guys !
Question 1) I need to chose an led driver.. which can work 18V and has PWM..
Question 2) Do you think that these batteries will suffice? i was thinking 3 would be enough! i was hoping to get about 8 odd hours of lighting
Question 3) I need help in putting together a charging circuit since this will be fixed.. i prefer using the Nokia male and female connectors here.. have a few lying around the house.
Question 4) Also an LCD or LED panel (easier the better) where i can read how much battery charge is left.. so that i can turn off the panels which i don't need and get more battery life
Question 5) Will a 10k Pot do for input for intensity control?
Question 6) What value resistors will I be needing on the panels?
I would really appreciate your help in helping me figure this out!
Thank you!
