Can UV LEDs cause injuries to health?

UV LEDs are common in computers nowadays, Can it be dangerous to who use the computer?

Bump, I would like to know too.

Well, without performing scientific experiments, I'd say "no, within reason". If they're in the case, and the case is on the floor, etc. you'd have nothing to worry about. If you have it on your desk in your field of vision, I'd move it. If you're staring at the LED's from a foot away or less, then yeah, issue.

If they aren't giving you a sunburn, I don't see any concern about anything else. Are you thinking cancer or what?

doesn't the window block some uv? uv leds in fans are used to light up the reactive plasitc right? isn't most absorbed? i dunno

I'd be most concerned about my eyes, not my skin. Two eyes per lifetime (maximum). Although I thought the eerie purple-ish color looked trick in photos, I passed on using UV LEDs for my LED panel for that reason (not being sure what their damage potential might be).

 

[0roo0roo]

aren't the uv leds they use just blue leds?

And what about the ElectroMagentic Radiation that the acrylic cases and windows don't block? See this article (search for EMR and start reading there) for a brief discussion. I would be interested in some scientific research on that topic.

Keep in mind that any attempt to educate people on safety here is brushed off with a

~ yeah right

kind of attitude (people are in love with Goo-Gone, for example).

*flees from angry mob of Goo-Gone fans :Q

I was interested by this so I checked it up. If they were unsafe, then so would be blacklights, and I've never heard problems ascociated with them.

Long wavelength UV-A is a normal component of sunlight, that, by virtue of its relatively longer wavelength, can penetrate the atmosphere. It is the least harmful and most commonly found type of UV light, because it has the least energy and is often called black light, and is used for its relative harmlessness and its ability to cause fluorescent materials to emit visible light - thus appearing to glow in the dark. Applications have included inspection of fluorescent surfaces, tanning beds, and treatment of skin diseases.

Depends on intensity and duration of exposure. It is known that UV light can modify cell structures - so it's best to be safe - exposure decreases drastically with distance. Glass blocks some UV but I don't know about plexiglass/lexan. Opticians can coat/treat plastic lenses to block UV - don't know if that means that the plastic lenses are totally UV transparent w/o the coating/treatment.
