Hi all, this is my first time posting so please be gentle. I’m designing an item that has LED lights incorporated into it. These need to be as bright as possible while being as small as possible. I am thinking of using 3-4 Cree XM-L2’s. However my question is in the design. I want the dome of the led to fit in a hole (Diameter of the LED) cut in a plastic sheet approx 3mm thick which will then be flush (or as close to as possible). This will then have a backing plate (foam or metal) to seal in the pcm and wiring.
As I’m new to all this can this even happen?
Do these LED’s need space for heat to transfer/circulate?
Will these LED’s be too hot to use next to plastic?
Do they need to be surrounded by metal to transfer the heat?
If this is not possible are there bright LED’s out there that can be close to plastic?
Any help would be great thanks
