There are LED lamps rated for enclosed fixtures. If you buy and use them in enclosed fixtures, your lamps will last longer.

A recessed can or “upside down” ceiling fan globe with an open bottom is technically an enclosed fixture since heat rises.

Typically fans with built-in LED downlights are engineered to actually dissipate heat - and they have a much larger area to do it in. Edison-format bulbs are inherently space-constrained.
