Hello All,
I'm building a FPV plane* that I want to rig for night flying. So I built a head light out of 12 Cree XP-G and carclo lens (16deg.) see:
All leds are on 10mm PCB from cutter, I glued them with thermal epoxy to a 1mm aluminium plate and added ribs between the four leds strings. As you see it's is no major heatsink, but the that light is mounted on the front of the plane flying around 25mph. With that amount of forced cooling, what current do you think it will it be possible to drive the leds at?
*FPV plane is a radio controlled planes flew via a camera mounted on board.
