The Wikipedia article defines a Dyson sphere as a system of orbiting solar-power satellites meant to completely encompass a star and capture most or all of its energy output.

I think there is a misunderstanding here about what that means in practice. Thermodynamics still applies. Energy has to be harnessed across gradients. Even if they wanted to only collect visible light, they'd have to radiate the heat somewhere.
