Topic: Help me chose the right LED? 4 x 4 square grid with acrylic top (Read 759 times) previous topic - next topic

Guys, please, I'm building a 4 x 4 LED square grid. So, I will build a 25 cm x 25 cm box with 3 separations horz. e 3 vertically. So, in total, we will have a 4 x 4 square grid. (16 squares)

Each square will have a red led. On top, a white-frost acrylic, so now I need to figure out which led will be best. So I get good illumination and also a good view angle, so it just don't show a red dot, but an uniform red square.

Here are some leds from eBay, if you find better ones (only eBay) please let me know, ok?




This leds I already have here, but the V.angle are terrible.

Thank you for any advice.

Best Regards, WilliamK

Here's a 8000mcd one (100lm) which is nice, BUT, its too pricy, and I don't get how I can solder it, will I require some special PCB? Why so much current compared to the other ones?

Hummm, I'm also wondering on using white-leds, as they have better mcd, and just check if the acrylic supplier have other frosted colors. ;-)

Here's some white leds, they are 20kmcd (20000mcd) which is much nicer. I could just use the frosted-white acrylic or maybe try some blue, red, green, yellow, and see what looks nicer. ;-)
