It gets reflected the other direction, into blackness inside the 
projector. The trick is, the tiny moving bits where it's focused aren't 
absorbing it, but rather the big heat-sink with the cooling system (for 
movie projectors) or fan (for little projectors).

It's the difference between using a rescue mirror or a smoke signal. :-)
