Kathy, et al,
The classification of LED's with lasers has brought heartburn to many a
product compliance engineer... how do you prove that there is no hazard
under both normal and fault conditions from the LED? Further, it is clear
that LED's are being used in high power applications which could be
hazardous... (Just look at the adverts for them)...
So, the IEC comes to the rescue... See IEC TS 60825-6: Safety of
products
with optical sources, exclusively used for visible information transmission
to the human eye. This standard classifies the devices into categories and
gives details for test and measurements for categorization and labeling of
devices.
I intend to ask manufacturers to issue a Manufacturers Declaration of
Conformity - which will probably be a letter - classifying their device and
declaring compliance to these requirements.
This is also a great opportunity for Test Houses to set up a component
program and provide independent certification of these devices.
Ah, thank you IEC, you have simplified my life - and placed the burden
on
the LED manufacturers...
