The requirements for visible LED's which are not lasers are contained
herein:
IEC 60825-6: Safety of laser products - Part 6: Safety of products with
optical sources, exclusively used for visible information transmission to
the human eye
The objectives of this technical specification are: - to protect
persons
from optical radiation arising from products incorporating visible diode
emitter sources, such as displays, indicators, electronic signs and
ignals; - to lay down requirements for manufacturers and installers, in
order that procedures can be established and information supplied to enable
correct precautions to be taken; - to ensure adequate warning of hazards
associated with accessible optical radiation from visible sources; - to
reduce the potential for injury by minimizing unnecessary optical radiation,
to give improved control of optical radiation through protective features,
and to provide safe usage of products by specifying user control measures.
Quick rules-of-thumb, which you seek are the result of experience
wherein
the investigator makes the measurement again and again under many
conditions. As far as I can tell, there isn't much data yet available for
these products.
Why not push the responsibility back where it belongs - on the
manufacturer - and get them to provide performance curves? These components
should be rated according to this...
The measurements are technically detailed (see the Agilent App notes on
their website). Why would you want to set-up to do this, when the
manufacturer should have the info already...
So, keep pushing back on the supply chain... Let's get these folks in
the
safety loop...
