LEDs don't really emit in the UV, unless specifically designed to do it. This is a bandgap property, a fundamental part of the material the LED is made of, so it's not changing any time soon. The phosphors in white LEDs shift the line spectrum of the (usually) royal blue primary dice down, not up, so they're not going to cause trouble either. LEDs are not blackbody sources, which is actually useful here instead of annoying.
