Is there an adverse affect if a sphere world is built around the only sun in a system with populated worlds?

I mean theoretically you are blocking all light from the Sun so do the planets become uninhabitable?

Edit: And what about ring worlds? same question.

Nah, the solid sphere still lets out practically all the sun's energy. It's just seriously red-shifted to the infared. Nothing a technologically advanced race can't handle.
