LED Lamp Conversion for Fluorescent Ring Lamps

A set of parts that can be used to convert and rewire fluorescent ring lamps to LED. These specific parts are sized for converting a ~1960's Gruber magnifying lamp—which uses a Philips TL-E fluorescent bulb—to an LED lamp, using Integral LED lighting strips and drivers.

The parts are parametric and built using build123d; you can customise them yourself using the code available on GitHub:

• Cord Clamp
• All other components

Note that those are permalinks to the repo to ensure they always work, but you may wish to look at the latest in the main branch to pull in any future updates.

How to actually convert the lamp is an exercise left to the reader, but the attached files—and those that can be built from the repository—contain the following:

• a ring to which LED strip lighting can be attached; it is printed in pieces to fit on a print bed, and can be glued together
• brackets for mounting the ring into the clamps which held the original fluorescent bulb; these are designed for M3x5.7mm threaded inserts
• a plate to mount the LED driver into the housing where the fluorescent bulb's ballast would mount
• a new cover for the upper electronics compartment; this is specific to the Gruber lamp and probably won't help you
• a threaded insert which can be used to replace any worn/broken cable pass-through on the lamp body
• a strain relief and cord covering which can mate with the threaded insert; this is nice if you have braided cable which cannot pass into the lamp body, as I did
• a cord clamp which can be used to ensure the cord cannot be pulled out of the lamp

I printed these in PETG; the LEDs don't get notably hot so I'm not expecting any deformation of the LED ring or any other parts.

Warning: Models are not correctly oriented for print; be sure to arrange them as necessary in your slicer.
