The LED's are likely not emitting light at the correct frequency to activate the fluorescent dyes.
Sunlight and incandescent light are more or less full spectrum. LED's and fluorescent lights tend to emit one color, or UV, and have to be doped with phosphors to give a decent light output. As a side note, you'd think just red + green + blue would be sufficient, but that actually produces garish light. A more full spectrum emission results in a higher Color Rendering Index. So likely whatever phosphors the LED is using, don't emit any UV.
Ironically, there are UV LED's easily available, though I doubt you will find any in this form factor.
