Dear Teachers, could you please check the following sentence for grammar and vocabualry?

Your infinite cheerfulness and kindness, like the luminous rays of a never-setting sun, inspire only the best in all of us.

Thank you very much for your help!

Yes, it sounds fine to me too. Some people might say that 'luminous' is already included in 'rays', and so 'luminous rays' is a tautology.

But x-rays are not luminous.
