Following is some helpful information on UV rays and alternatives to the problem. Light Emitting Diodes. LEDs (Light Emitting Diodes) do not generate UV radiation because they are lit through a process which involves electrical current flowing to semiconductors. Unlike incandescent and CFL bulbs, LED bulbs do not require a filament or gasses which use heat as the source of light. While there is a slight amount of heat that is generated, it is not in the infrared or ultraviolet portions of the light spectrum.
