Heat Insulating Plates

[rob171171]

Hi

Really not sure where this post should live so Mod feel free to move if deemed non-applicable here.

I am looking for substance, relatively thin in thickness that will prevent / reduce heat conduction been emitted from 35Watt halogen bulbs.

I have 8 x 35 watt halogen bulbs mounted approx 12 mm away from 6mm pine wood. The purpose of which is to illuminate the wood - cut out to display countries of the world. The halogen bulbs are controlled by dimmable switches.
The problem is that even after a short period of time the boards tend to heat up quite a bit and I'd like to see if there is some material that could be screwed to wood in front of bulb that protects the wood by preventing / reducing the heat transfer.

Thanks in Advance for any suggestions

The heat has to go somewhere.

In principle it's possible to make that "somewhere" the rest of the room or something so it doesn't do any harm.

But a better solution would be to replace the halogen lamps with LED ones.

Putting a 20 dollar filter in front of each lamp is probably more expensive than replacing them

Plus some fans to remove the heat. I agree: LEDs are the way to go.

Double spaced Mica sheet should help here.

Thank you all for responses

 

As far as I know dimmable LED's are not available and one of the key features of this project is teh ability to dim the lights as it affects the entire mood of the room.

How will the Mica help dissipate the heat?

It won't.

I thought you asked for an insulator.

 

Mica is also fireproof.

'Dimmable LED' gets me over 4 million hits in Google, so online they are certainly available.

I own some dimmable LED bulbs (which are also wi-fi enabled so I can adjust them from my phone, and also do colors)

Dimmable LED's controllable remotely over WiFI - now that sounds like another project! I like it. Ok so LED's ar ethe way to go here obviously. Thank you all

As far as I'm aware, all LEDs are dimmable.

Hey Shaken - Have you any details on the WiFI enabled LED's. Cna you control via iPhone App?

Mine are from LIFX, and yes there's an iPhone app. (originally they were a kickstarter product but are now commercially available) The bulbs aren't cheap, because of all the bells and whistles. (the app is free) These particular bulbs run hotter than other LED bulbs, so they may not be a solution to this particular problem.

Thanks Shaken and everyone else for your inputs
