Notes on materials:

A lot of this I had lying around. This may not be the most practical solution, but I made it practical for what I had. If you want to check out why I had so much PVC 

I used the foil insulation as a backer for the LED strips. I know this material could be rigid, but also collapsible. If you can think of another way to back this project with a different material that you have lying around, by all means, use that. I will say, the foil insulation is surprisingly tough, and stands up great to manipulation and rolling!

Given the length of the roll of LEDs, and the width of the roll of insulation, I decided to cut 9x 21" strips of UV LEDs. I did some math and figured out I would want to space them about 2.75" apart - I was concerned if they were any further and it may begin to affect the quality of the light being emitted.

From experience, I know that the LED strips WILL NOT stick well to the mylar sides of the foil insulation, but the adhesive backing on the strip does stick to masking tape.

I measured out the distance I could span with the 9 strips, and made some marks as to where I wanted the tape backer strips to be placed.

I ended up with a pattern for a 21"x21" square of LED strips made.

Cutting apart the LEDs is SUPER EASY. The roll has designated spots to cut every 3 LEDs. Where you slice the LEDs also becomes the soldering junction.

Next up was removing the strip for the LEDs adhesive backer and pressing the strips into the lamp's surface.

I really squished the strips down quite a few times to make sure that the tape and the LED strips were completely bonding and I wouldn't have to worry about strips slumping off while I was trying to use the lamp.

There was only one wire junction on the LED strip, at the beginning of the strip, and since I cut the LED strip into many segments, I needed to add more wire junctions to run power to the LEDs.

I began by cutting down the length of wires I would need - two lengths per strip, each pair longer than the last to meet at the PCB power junction after these were connected to the strip.

I set my soldering iron just hot enough to melt the solder, but not so hot that it would burn the plastic or mylar foil while I was making the connection. If you're soldering iron doesn't have variable heat, you may want to complete this step before attaching the strips.

Soldering to LED strips can be a fickle thing, so to save time and be able to work more nimbly, I tin the component contact and the wire separately, then make the connection by quickly melting the two together. ( See video for better demonstration)


Cable management is key for projects like this where18 long spindly wires are flying around, so I use zip ties to make sure my connections wouldn't be swinging all over the place.

Using trusty masking tape and clear packing tape, I was able to come up with a pretty clever solution. I just folded the wires back over the other side of the insulation, 'pinned' them with masking tape, and then secured them with 2" clear packing tape. It's hard to tell it's there in the photos, but I promise, it is.

Once the wires were more or less secured, I went down each side of the lamp and secured the wires...
