How to get lighting text effect

I recently follow this account and really love how the text is projected on the model.

I tried doing it with a projector however the projector also projects black light and it does not give the same effect at all.

How could I achieve that kind of effect?

PS: If someone also knows how to get this kind of red backlighting that would be awesome.
