I bought these nice Philips Led lamps couple of years ago and they were supposed to fit into my ceiling where I measured free height of around 8cm which was enough for them to fit. Unfortunately, not every hole did have the same free height so several of them didn't fit. As a result, for a long time those lamps were simply hanging there as I didn't want to buy any new ones (see photo). Having a 3D printer now, I thought of making my own design where the lamps would fit and still look good on the ceiling. Since I like the look of the lamps (and somehow want to be careful about the heat they do produce), I've chosen for an open design. The design consists of 2 parts having a lamp holder and the cover part which you simply push into the ceiling.

I already noticed 2 things with it which I'm sure can still be improved being:
- The cover might get little loose since it's just being pushed into the ceiling without any clips or so
- The holder / cover does not push the lamp into a straight position necessarily so you need to ensure it's straight manually (combining the holder / cover in a better way could probably solve that)

But overall, it does the trick and looks ok to me.

Any suggestions / ideas welcome.

@Groaker, thanks for your comments and indeed those LED light bulbs do generate quite a lot of heat. I originally bought them to be fully enclosed in the ceiling but while taking the necessary measures for my new design, I noticed how hot they could become. As such I went for a more open design where the lamp is enclosed for less than 20% or so. As such, I do think (hope) it gets enough airflow.

LED light bulbs seem to have a tremendous issue with heat. I have had some name brands die in as little as four hours. Current flow increases with heat, and heat increases with current flow. This sets up a positive feedback cycle in ceiling enclosures. At the cost of these bulbs one would think that a constant current circuit would be part of the design.

This does not happen when the lamps can be cooled by an adequate airflow. Be sure to leave holes in the shroud for ventilation.
