Embedding LED Lights in Epoxy Resin

Introduction: Embedding LED Lights in Epoxy Resin

About: Hi Everyone, I'm Jeremy Hoffpauir. I write instructables about unique DIY woodworking and home improvement projects. I use unique design elements with a rustic coastal style in my creations such as epoxy...

I received many questions/comments regarding a technique I used to embed LED light strips in resin in my previous LED wall art project.

Consequently, I decided to write an instructable which further elaborates on this technique.

Keep in mind, I use the term 'embed' in this instructable as a synonym for submerge, cover, and encase.

Things I Used in this Project

Epoxy Resin

Hot Glue Gun

1/4″ clear tubing

LED UV Light Strip

Step 1: Determine What Is Best for You

There are many ways to embed LED strip lights in resin. If you are interested in the different techniques, continue reading this step. If not, simply go to the next step.

Essentially, I've either used or considered using the 3 techniques outlined below.

Create Tunnel in Resin

Hands down, this is the best technique for embedding led strip lights in resin and the technique used in this instructable.

  • Pros
    • This technique makes it easy to replace broken LED light strips or upgrade LED strip lights to different colors.
    • Furthermore, this technique helps UV LED strip lights to efficiently charge the glow powder. If you are interested in resin glow powder, be sure to visit my live edge beach glow table.
    • Also, the tunnel hides the LED lights from view.
  • Cons
    • Ultimately, creating a hollow tunnel is more difficult than the other techniques.
    • Luckily, this DIY tutorial provides detailed instruction on how to embed LED strip lights in resin using this technique.

Glue LED Light Strips

This technique is widely used because it is simple. Additionally, most LED light strips have an peel-off adhesive on the back.

  • Pros
    • Ultimately, this technique is simple and convenient.
    • Additionally, this technique can be improved by routing a groove for the LED lights to rest flush with the wall art or table.
  • Cons
    • This technique makes attaching LED strip lights to epoxy resin easy; however, it has 2 issues.
      • First, the peel-off adhesive lacks proper strength to hold the LED lights in place.
      • As a result, they eventually come off with time.
    • Super glue can be used to solve problem 1. However, it makes a mess and it is difficult to remove.
    • Essentially, problem 2 solves problem 1; however, it creates an additional problem.

Fully Encapsulate LED Strip Lights in Epoxy Resin

Since I don't recommend this technique, I will only review the cons.

  • Cons
    • First, epoxy produces heat during the curing process and may damage the LED light strips.
    • And, it is impossible to replace the LED light strip.

Step 2: Prepare Tubing and Rod

First, 1/4" clear flexible tubing works best. The tubing does not stay straight and prefers to curl. In turn, I recommend to use something rigid to keep it straight. Also, be sure whatever you use is plastic because it will need to be cut in later step. I happen to have an old plastic wire fish rod which fit perfectly..

Then, use hot glue or silicone to seal each end.

Next, place the tube in the middle of the wall art.

Keep in mind, you will need to trim each end if you install the tube and rod as mentioned above.

Often times, folks trim each end anyway to square up the wall art. Therefore, it isn't an issue..

Alternate Option

There is an option if you don't plan to trim each side of your resin project.
First, drill a hole in the resin mold the slightly larger than tube (3/8" should work) into each end of the resin mold. The tubing and rod should be roughly 3 to 5 inches longer than the table.

Next, slide the tubing through the holes. Essentially, this option eliminates the need to seal each end with hot glue and it eliminates the need to trim each end. Simply use a razor blade to cut the tubing after the rod is removed in a later step.

Step 3: Thin Bottom Resin Layer

First, I recommend pouring a thin layer of resin, allow this to cure, and then add the tubing.

Obviously, you should only do this if you are using transparent resin or to charge glow powder via UV LED Lights.

Ultimately, this is a cleaner way to ensure the LED lights are embedded & suspended in the middle of the resin. As you can see from the pictures, I didn't do this which caused me to have to paint the back of the LED light strip.

Step 4: Pour Resin

This is an easy step. Ultimately, just pour resin as you planned to do.

Step 5: Trim Ends and Remove Rod

First, trim off each end with a circular saw or table saw.

Additionally, make sure to cut the end of the rod on each side. This exposes the rod which makes it easy to remove.

Next, expose the rod from the other side by pushing it a little.

Then, completely remove it. If you look closely, you can see how I didn't completely cover the tubing with purple resin.

Step 6: Inspect Tunnel

First, inspect the tunnel once you remove the rod.

It should look like the picture in this step.

Step 7: Install LED Lights in Resin Tunnel

First, tie or tape the led light strip to the rod or device used to keep the tube straight.

Additionally, I prefer the LED lights to face down towards the rear of the table.

Next, pull the LED strip through the tunnel.

Then, cut the LED strips between the contacts. Or, bend it around the end towards the back if it will be powered via a wall outlet.

Also, be sure to leave about 5" in excess to power the LED lights.

    Question 2 months ago on Step 2

    Any other ideas on how to ensure the tube doesn't collapse. Very new to the river tables and all things epoxy, and unfortunately allowed someone to talk me into doing a 7 ft by 4 ft dinning table. Anyway Having the tubes at the end at the caps of the table might not be workable, so will have to stop it some where in the ends of the table underneath. I am looking at inserting a box under the table the then run the tubes to the box. Another solution is to angle the tubes from the bottom and use air or gas sealed into the tube to keep it round and straight. Any comments on this. The client wants 4 led lines on the table. the epoxy river goes from 2 to 8 to 12 inches based on the curve of the slabs. He is an AV tech so wants the ability to land aircraft with the lights. Just kidding but he wants it bright.
