This becomes a major issue when dealing with high density applications or high ambient temperatures, usually requiring the use of heat sinks.
I'm currently working on a dual mode dome light replacement for this car that will have a pleasant accent light in a select-able color, and then a main flood light using Luxeon Rebel Whites. Due to the packaging and power draw (20W), thermal considerations were the number one priority during board design and packaging.
The only way to avoid killing your LEDs in this application is to use a high-temperature "light tunnel" if you will. It would need to be some sort of clear plastic/acrylic that would allow you to remotely mount the LED and then run the light to the position in the projector you really wanted.

I was looking into making like a fiber optic tunnel and maybe flaring out the end to give it a better light dispersal, idk if that would work as I've never used anything like that before. Attach the led on the bottom of the inside housing and rout it up that way.. I think it would be far enough from the heat of the light, and I would mount it to its own heat sink
They have some acrylic rod at the hobby shop, making a small recess in one end and polishing it up installing that to the led, wrapping the tube in heat shrink the heating it up and bending it to where I need it to go, but unless I flare it I'm thinking it will only shine a spot on the top of the housing.. Even flailing it idk if it will spread the light much more
