LED lamps emit no Infrared or Ultraviolet radiation. CFLs (and tubular fluorescent lamps) generate light by exciting the Mercury vapor inside the lamp with electricity, generating Ultraviolet radiation, which stimulates the phosphor coating on the inner surface of the glass bulb, causing it to re-radiate most of the Ultraviolet radiation as visible light. LED lamps generally create “white” light by using blue LEDs and a phosphor coating which re-radiates some of the blue light as longer wavelength light (yellow range of the spectrum), together appearing as white.
