I would like to learn more about electronics and circuitry by making a LED light panel. I have questions about how to calculate the number of LEDs I need, soldering, and how to diffuse the light.
I would like to make LED light panels to mount to a basement ceiling, like the following examples (1
). I know mine won't be as pretty. It's a learning experience!
My plan, inspired by this video
and this previous question
is to make a LED panel that will fit into a 10 inch picture frame and then get mounted to the ceiling. There won't be a battery, I plan on wiring it to a 12v power supply. Dimming is intriguing, but seems like a v2 feature.
Based on the previous question, I am probably going to go with this roll of LEDs
in Warm White (3000-3500K), unless anyone has a better suggestion.
1) The video would have the LEDs laid out on the bottom of the box. Should I be arranging the lights like in this instructable
? I worry that won't be bright enough.
2) How do I calculate how many LEDs I need per panel? Assuming I am trying to replicate the light output of a 60 w light bulb (800 lumens.) Will the resulting output from the panel be equal to the number of LEDs multiplied by the amount of lumens per LED? The website says each LED is 4-5 watts. Solving for x, that is 160 LEDs. That seems like a lot.
3) I am going to ask a friend to show me how to solder them together. Can I use speaker wire? I don't know if Radio Shack is the best place to buy it, but they do have white wire
which will blend into my ceiling and walls.
4) The light panel in the video has super frosted glass. Can this be simulated? I don't know if the self-adhesive vinyl frosting for windows would be thick enough. Perhaps two layers?
Thanks for your help. I am excited on learning several new skills, and fixing the terrible lighting situation that is my basement.
