Grins at rays (5)

Ross

I believe the answer is:

beams

I'm a little stuck... Click here to teach me more about this clue!

This could be a double definition.

'grins' is the first definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'rays' is the second definition.
('beam' can be a synonym of 'ray')

'at' acts as a link.

Can you help me to learn more?

(Other definitions for beams that I've seen before include "Smiles; joists" , "Rays of light" , "Smiles broadly or sunnily" , "Shines" .)
