I'm looking for an LED that generates a beam of focused heat. Ideally this beam would be no wider than 1 - 2 inches when the LED is 2" above the surface. I want to put about 8 of these LEDs in a circle to shine down on a plastic object to keep it warm.
Currently I am using the heat lamp to accomplish this same task from rougly 10 inches away from the object. The melting point of the ABS plasic I am heating up is 105c (221f). I don't need to melt the plastic but I need to keep it fairly warm after melting it so that it does not warp. The goal here is to slow the solidfying speed of the ABS plastic so it remains flat.
As I said... This works with a heat lamp but the heat. The heat lamp is big and bulky so I would like to find a bunch of smaller lamps that I could use at a closer distance to generate the heat.
Do LEDs exist that can emit focused heat? What specs should I be looking for? I assume UV or IR LEDs could do this. What wavelength? What spec do I need to look at to determine how much heat it will generate?
