case of classified areas, an optical source can
represent a trigger when it exceeds certain values of

protection is applied when the radiation is not
confined in a closed space, but exits the device (as
in the case of the light beam coming out of the
lighting equipment) and has the purpose of ensuring
that, even in fault conditions, the optical power
emission or the optical irradiation emission does not
exceed the expected levels.
“This result has been achieved - explains Cortem

the use of specific multiled board plates and the
