Default Why do LEDs generate heat?

Why do LEDs generate heat? I want a technical answer not "because
they're inefficient". And will we ever make them more efficient?

Besides the inefficiencies in the LED itself which other posters have
covered, LED lamps have some current regulation or power supply built-in
which will not be 100% efficient and thus generates heat.


I have a LED bulb (60W equivalent) in a lamp here. The bulb itself
doesn't get hot like an incandescent bulb does. What gets hot is an area
around the base.
