I am a newbie with these type of applications, but I am trying to see if this idea would work out.
Essentially what I am trying to do is build a large panel 2ft x 20ft that will act as one large light strip. I want to have light dissipating material to spread the light evenly over the entire thing. Behind that I want to use a number of LEDs to provide a low-power and low-heat solution.
Right now I am looking at LEDs in the range of 25-50 lumens. Would this work out to provide more even lighting, or would it be better to use LEDs with higher output?
Would I still need a heatsink? Say I use this 26.8lm LED, each individual LED would consume just 0.2 watts. I would be putting this in a grid with roughly 30 LEDs per 2ft x 2ft tile, but I'm not sure how much energy would be wasted as heat.
Is there an idea material for the panel so that the lighting is most evenly distributed?
