Some questions from an LED newbie.
I am working on a couple of LED test projects. I haven’t done this before so might ask obvious questions.
One is a small 1×0,5m sign (with an MDF plate back) And a bigger, 3.2×1.4m sign.
The small sign is 15mm opal that is routed so that letter just has 3mm thick walls + 20 PVC foam face with a track routed for LEDs.
What kind of LEDs would you use in such a thin sign?
Most I find are supposed to be used with 40+mm channel letters. I have Lucoled BL10s in “L” and generic LED from a local shop cut and joined in “OS”.
Generic LEDs are not really viable, lots of work to bend them to follow the shape and they are still visible a bit.
I have covered the back of Opal with chrome vinyl to reflect more light.
The bigger sign has letters with 35mm from the back end opal face. I used 21 Lucoled BL16 LEDs in “L” and I am happy with the result.
I used Lucoled BL10s in “C” and they had to be placed with just a 1cm gap to get an acceptable result (top of the “C”) If I increase the gaps LED become visible (bottom of the “C”).
I also ordered SloanLED BendoLUX but it will take two weeks for those to be delivered.
Sloan LED has only 1 distributor in Norway. So another week l I will be able to test those. The LucoLED will come much much faster.
Anyway, I calculated that I need 445 of the BL16s for the big sign, and that sounds awfully a lot.
Or is it normal to use hundreds and hundreds of LEDs in such a sign?
Would something like LucoFlex fit this kind of project better?
I have attached some photographs.
Thanks and best wishes from Norway.
