LED Tutorials - Light Box Diffusion Guide

When using LED Strip Lights or LED Modules for your light boxes and channel letters it is important to know the right techniques to be sure that your LEDs can not be seen through the acrylic or plastic cover. Visit this tutorial to learn proper spacing techniques to be sure that your light box and channel letters glow as one even light. Find the produt you would like to use below for a light box diffusion guide, or as always, you can give us a call at 775-636-6060 with any questions.

1.) Measure the Depth of your Light Box and Determine Proper Light Spacing
To first start your LED light box or channel letter project you must first measure the depth as well as the width of the box or letter. The depth of the box is important due to the beam angle of the LED Strip Lights and Modules. At 120° beam angle the deeper the light box or channel letter the less lighting products you will need since there is more space for the beam angle to grow and diffuse. See the light box diffusion guides below for further reference on lighting spacing.

2.) Use Masking Tape to Temporarily Mount LEDs before Final Installation
It should be common practice to always do a mock setup in a small space of your lightbox, using masking or scotch tape, to be sure you have proper diffusion before final installation of the LED Strip Lights or Modules. It is a very common mistake to install your LEDs and then find out that you see LED hot spots right through the acrylic cover because your LED spacing was not correct. This is why we can't stress enough how important this step is.

3.) Use Colored LEDs on Colored Acrylic for Vibrant Lighting
People don't always realize that if you are lighting a sign or light box with a colored acrylic cover that you will get much more vibrant and colorful results if you use the same colored LED lights. Using White or Warm White LEDs on colored acrylic will give the sign a washed out effect. As you can see from the example to the left using colored LEDs on Colored acrylic gives a much more appealing lighting effect.
