Diffused LED Answered


I am working on a lighting project. Right now I have a typical yellow LED (like so http://www.sparkfun.com/products/532) mounted in a 5" tube. It is shining through a frosted acrylic sheet at the end of the tube, 2" away from the LED. it creates a circle of intense light on the acrylic that is about 3" in diameter and then some ambient light around it. Are there any LEDs that are designed to diffuse light more so that the circle of intense light would widen and be a bit less bright?





i think most people's methods for making diffuse light LEDs is to rough up the LED with sand paper (enough to make the LED plastic look cloudy). that should diffuse it enough to prevent the spot light type effect that you've got

There are several ways of diffusing the light from LEDs - have a try of the search box at the top-right of the page.
