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.
