[General/Vampire] Would a vampire under an invisibility spell be immune to sunlight?

Invisibility makes light completely pass through the subject, so part of the spell must create an illusion of what the user would see (as no light would be absorbed by their eyes).  

As invisibility would cause sunlight to completely bypass a vampires body, would it be a way for them to walk about in the daytime?

In described circumstances, sure.

But as usual details would depend on exact circumstances - does the spell ACTUALLY makes someone transparent? Or maybe it just makes an illusionary image of  what's behind him. Or maybe it bends light around? And how exactly vampire is vulnerable to sunlight? Is it physiological burn at UV-light, like in Blade, or an ancient curse of some kind that affects just the light of day regardless? That one wouldn't care about being transparent for example, if sunlight would hit even if it goes through... And some vampires are not harmed by sunlight at all too...
