Which glue for the led?

[Chuber]

Sorry if this was already posted in the forum. I have an aluminium heatsink and the Luxeon Led Emitter, and i'm wondering which glue do i need to use for put these 2 parts together? Remember i live in Argentina and we don't have the same glues you have there. If any can show me any pictures of the glue... maybe i can get one similar here. I think i can use regular contact glue, but maybe i'm wrong... Thank you.

If their MHS pieces, you shouldn't need glue.

By your question I would say you are not using the mhs led holder, so the luxeon is mounted by drill two holes in the heatsink to secure the led with some plastic screws. You can use a thermal compound to help with heat transfer like is used on computer CPU's.

I mixed thermal compound and contact cement on one setup that I did, it worked ok but I really had no way of knowing if the LED was getting enough heat transfer so I switched to what Do-Clo said and just drill and mount with nylon screws ala TCSS.

Ok... but i do not have the Luxeon Star. i have the Luxeon emitter, it is the same but it doesn't have the metal star under the led... so there is no place to mount the plastic screws. I was thinking in thermal paste... do i also need a contact cement? Do you know if this mix works? The heatsink and blade holder i have are aluminium. I have them made from a frien of mine who works with aluminium. They are the same the ones you use...

You are going to need some thermal epoxy to insure that you get good heat transfer and it will hold the led emitter in place.

but if i mix thermal paste and contact cement? do you think it will work?

Very doubtful, I would be worried about heat transfer to the heat sink.
