LED edge lighting

Pages: (1/3) > >>

Generic Eric:

Just brainstorming here, if I wanted to edge light a larger piece of plexi, say 70% of a 6'x3' sheet what type of LED and how many do I use?

Is it this kind?

lilshawn:

i can't tell from the pictures since they are quite blurry where it counts. but they look like 3528's

SMD LED's are described as their size in MILLIMETERS DECIMAL'D. IE a 5mm x 5mm LED would be described as a "5050" or "5.0 x 5.0" wherein a 3.2mm x 1.6mm would be "3216" etc.

RGB led stips are often 5050's and are very good at edge lighting because they are much brighter than 3528's are when set up in an RGB situation.

Shoot I should have just linked to the auction.  Have you done many edge lit projects?  I'd've keen to see some examples.  I'll check the auction tomorrow & make sure they are 5050s

I just got a roll of 5050's from DX.com for $18 + a few bucks shipping.
I want to see if I can use them to replace a back-light in a 21" 4:3 LCD monitor.
It's an old monitor with a low resolution and parts are non-existent for it.

so if my backlight experiment fails I still have a strip of led lights to play with. :)
