Wood frame

[Tombsy]

Can I use a wood frame for QB288 and heatsink? I have 6 of these boards, building a 2 x 3 array.

Was thinking 1 x 2 wrapped with foil tape.

I made a wooden frame for strips. Wood is a great material, of course its a little harder to find a balance in weight and strength.

don't see why not.... only 2 things I can think of...

the weight could be a issue with lower quality wood...( full of knots,warps etc) just got to be picky..
if you could get a hold of some cherry or hickory and stain it... that would be a purdy light!

boards/heatsinks won't be grounded... normally driver sitting on aluminium frame or if running remote driver.. a ground wire to the frame is used... you could ground to each one of the heatsinks instead of the frame..

My build had 4 75w drivers so the weight of the wood and the drivers started adding up. When I moved the drivers elsewhere things got more manageable.

Going full retard with wood is a very tempting idea, my first build was just quick and easy. Maybe make some homemade slabs of stabilized wood

I used a bit of 1x2 wood with my frame. I would say its stronger than the 1/16th thick 3/4 angle that I used also. And I dont think the foil would be needed unless you plan on running them real hot or plan on having a board sandwiched between 2 heatsinks. . Are you going to have a bracket between the heatsink and frame? If so that should be fine also.

Never heard of this before. Are you taking the black (ground) from the DC output and grounding it to your frame/heatsink?
I guess it would be the same as a car.

What wood did you use rdooski13?

What were you planning to do with the foil? reflection or heatsinking?

the green line on the a.c. side.. if your running a remote driver, you have to add a line if you want your light grounded... there's a great explanation here... I can't find it atm lol

ill edit this later when I have more time to dig

What wood did you use rdooski3?

It was some scrap I had so im not 100% sure. But it is a bit darker than the typical stuff at the hardware store.

Make sure you take your time and pick trough the pile and get the best/straightest ones also. Ive seen some pretty messed up ones.
