Umbrella offering light protection? (7)

I believe the answer is:

parasol

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

This could be a double definition.

'umbrella' is the first definition.
(I know that parasol is a umbrella)

'light protection?' is the second definition.
'parasol' can be an answer for 'protection?' (parasol is a kind of protection). I'm not certain of the 'light' bit.

'offering' is the link.

Can you help me to learn more?

(Other definitions for parasol that I've seen before include "Sunshade" , "Desert Shield?" , "cover" , "mushroom" , "Fair-weather umbrella" .)

I've seen this clue in The Sun.
