I googled what radiance means and the result is

light or heat as emitted or reflected by something.

Could you explain the role of "as" here? I can see no reason to put it in, as sentence without the preposition also makes sense and has the same meaning.

    Did you look up 'as' in the same dictionary you found 'radiance' in? There are lots of different uses, admittedly, but one does fit.

as
pronoun

—used after same or such and chiefly dialect after a substantive not modified by same or such

So, your example means light or heat such as that emitted or reflected by something.
