Actually, the concern is worldwide. It starts with IEC 60825-1 which covers
emissions from lasers and LEDs. IEC 950 has a normative reference to IEC 825
(an earlier revision of IEC 60825-1). IEC950 says that the national members
are encouraged to apply the latest revisions of the normative references. UL
1950 references IEC 825-1:1993 which has the same LED requirements as IEC
60825-1.

Subject: RE: Products with high power LEDs
Can somebody tell me what Europe's concern is with the LED's. I
understand
the hazards of laser's, wavelength, power, durations et al but I
don't know
what Europe is trying to protect.
If this was just recently discussed please forgive the
transgression. I have
been sitting in those flying horizontal aluminum tubes for the last
week and
have been unable to actually read any of these e-mails. Certainly,
you can
respond to me directly rather than the list.
Thanks
Gary

The Low Voltage Directive is definitely applicable
for the
230V configuration.
A 24V device is SELV, and has no potential for
electric
shock. If its input
power is limited to under 100VA, it does not require
a fire
enclosure per
EN 60950. So, the only major safety issue remaining
is
possible exposure to
the laser under fault conditions.
EN 60825-1 (as I recall) has nothing to do with the
voltage
required to power
the host equipment. So it applies in either case.
