ᐅ Mounting LED strips between drywall and wooden beams

Hello everyone,

we have an exposed wooden beam ceiling and are planning to install indirect lighting above the central beam using LED strips (see marking in the picture). The LEDs are intended to shine sideways to the right, so they will be positioned “standing up.” What is the best way to attach the LED strip channel between the drywall and the wooden beam? The roof pitch is about 30° and I have roughly 2 cm (0.8 inches) of height available for the trim.

Should I fix the mounting bracket directly onto the central beam and press the trim flush into the generously applied plaster? Or should I bend a trim with a one-sided ridge and embed it in plaster with a shadow gap toward the central beam?

I would appreciate any advice.

Thanks in advance.

Regards, Chris

There are rails at all angles. Just stick them on – the LED strip should be self-adhesive. However, I would aim slightly upwards. Like this, for example.

For fastening, I would use angle rails as @nordanney suggested. I built something similar in our main bathroom.

But a thought: How is the ceiling finished? Gypsum with Q4 finish, non-woven wallpaper, plastered and painted white? Please keep in mind that with grazing light, every unevenness is visible, and the ceiling can end up looking like a bumpy ski slope after apres-ski.
