I always thought that glass prevented the transmission of UV light - you cannot get sunburn through a window for instance. Surely the glass in the lenses of the microscope would block the UV light. In any case I cannot see anyone acheiving a suntan from a white LED which suggests that it is less damaging than being outside on a sunny day.
I suspect that there are no risks at all as long as the lighting level does not hurt or dazzle your eyes.

hi Nick
please be careful Nick
glass does not prevent the transmission of UV light; I work in museums, where damage to objects by UV is a major problem; while glass cuts out some UV light it does not prevent it - we use special film on windows, on lights in cases, etc.
have you never noticed fabrics fading in sunlight? that's done by the UV in the spectrum
you may correct that the amount from a small torch going all the way through the multuple lenses of a compound 'scope might be minimal, but don't forget - you're looking at a focussed beam of light
I would contact a local specialist lighting company - let on that you would like some samples of anti-UV film as you're thinking of doing up your conservatory
and put that over your light source
sorted
cheers
