Famous Led Light Uv Emission Ideas. From the picture, we can see that the emission spectra of mercury lamps are continuous, ranging from ultraviolet to infrared. Web in a light emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or uv), a process called electroluminescence.
The blue emission (440 nm) is due to the transition of 3 p 1 → 1 s 0 from sb. Web there are sources that say that led lights do not emit uv rays at all. But some quarters say that this is not entirely an accurate statement.
