Is there any UV light in LED lighting?
In conclusion, does LED lighting contain Ultra Violet Light? It depends on how you look at it. White Light LEDs produce some UV light, but they emit less.
Is it bad to look at UV light?
Looking directly into a UV LED can be harmful to the eyes. It is best to limit exposure to UVA producing product. The UVC and much of the UVB spectrums of light are primarily used for germicidal and sterilization purposes.
How much power does a UV light source produce?
UV LED sources continue to increase in power. The output of UV LED’s has gone from milliWatts/cm2 of irradiance to Watts/cm2 of irradiance with some systems in the neighborhood of 10W/cm2. Output irradiance is usually one of the first numbers an LED manufacturer will share with you.
What kind of light does a led emit?
Many UV LED products emit in the UV-A range, and are commonly referred to as blacklights. Waveform Lighting’s realUV ™ LED products, for example, emit at 365 nm and 395 nm, and are used across a variety of applications such as fluorescence, curing and blacklight artwork.
Is there enough UV light to pose a health risk?
In reality, the final amount of emitted UV is so small as to statistically say that White Light LEDs do not emit any UV light. So, is there enough UV light emitted to pose a health risk? No, the amount of UV light emitted by White LEDs is well less than a single percentage point.
Why does white light come out on LEDs?
With White Light LEDs, the thickness of the phosphor coating and the amount of yellow in the phosphor itself, in part determines the amount of the brilliant blue light that is absorbed by the phosphor. This results in the different CRI and Kelvin Temperatures of the LED.
Is there a health concern from using LED lighting?
Most really seem to be worried about one of several things: Is there a health concern from using LED lighting, and/or is LED lighting better than other light sources for protecting UV film and preserving artwork, artifacts, and décor from ageing and discoloration? To answer these questions we must initially look at how White Light LEDs are made.
