LUMA LINK Fiber Optic Lamp · fiber optics

Hello everyone,
I am pleased to introduce the new LUMA-LINK lamp. 🥳 It bears this name because light connects one side to the other via fiber optics. This allows for truly extraordinary light displays.
When assembled, the total height is approx. 28 cm / 11 inches.

A Wemos D1 Mini ESP8266 controller with WLED software controls the lighting effects. This controls two 10-pixel segments of a very high-resolution LED strip with 144 LEDs per meter. Another 10-pixel LED strip is mounted in the center. The light then shines out between the two sides of the lamp, creating an atmospheric glow.

A special holder for the LED strip and fiber optic cables is included. To make the assembly of the LEDs to the light guides and the wiring a bit easier, the base is printed separately and attached at the very end.

Parts List:

1x 1 m addressable LED strip, 144 LEDs/meter
2x 5 m PMMA Fiber Optic Cable 5 mm side glow
1x ESP8266 Wemos D1 mini Controller with USB-C
1x Power Supply 5 Volt with 2 Amps
1x DC Power Jack 5.5 mm x 2.1 mm
1x Resistor 470 Ohm
1x Capacitor 470uF
1x Cable 22AWG 3-Pin
1x SM JST 3-Pin LED Connector
Miscellaneous: Soldering iron, hot glue gun, PTFE tube cutter, PMMA adhesive

WLED Wiring Guide: https://kno.wled.ge/basics/wiring-guides/

You need 3x 10 LED pixels each from the 144-px LED strip. I recommend connecting two of them in parallel so that the beginning and end of the fiber optic cable are automatically illuminated with the same color. This creates a more intense color effect.
The third strip can be connected in series or to its own GPIO. GPIO 1, 2, and 3 can be used as data outputs.

PMMA Fiber Optic Light Guide Instructions:

Cut ten pieces of PMMA fiber optic cable, each approximately 65 cm long. First, feed it through the top sections where it floats in the air, so that the ends are approximately the same length on both sides. Only then press it into the side recesses and place it into the lamp's base. The fiber optic cable is only pressed into the designated recesses. No adhesive is needed here.

Once you have laid all ten light guides, you can score them to the same length with a cutter, then cut them smoothly. (Permanent markers do not hold well here)

A smooth cut is best achieved with a PTFE tube cutter or a very sharp cutter, with which you cut the light guide using sawing motions. This ensures that the cut edge is as smooth as possible and allows plenty of light into the light guide (please do not use pliers)

Now glue the two LED strips into the LED holder. The cover with the ten holes can now be slid in and perfectly aligned with the LED chips. Then, the ten light guides are inserted into the holes. If possible, secure the printed LED holder to the housing so it cannot slip. You can also use special PMMA adhesive to secure them in the holder (hot glue will not hold on the fiber optic cable).
Repeat this step on the other side.

The third 10-pixel LED strip is attached in the middle. This is controlled via an extra GPIO, or connected in series to one of the other two strips, so you have more control over the light management. The strip is glued into the holder and then clamped.

In the final step, the lamp is placed on the base pedestal. Inside, you can hide the light guides as well as the electronics & cables. The base also contains the DC jack for the power connection.

My two lamps were printed with BambuLab PLA Matte charcoal and with Sunlu Ashen Concrete PLA

And now I wish you a lot of fun printing, crafting, and programming fascinating lighting effects 🤩
