摘要：System has an optical sensor (1), an aperture with the optical element (2) withthe changeable permeability and an activation light (3) emitting radiation, which isdetected by the optical sensor (1). The activation light is connected with the switch (4)and it is placed within the reach of the optical sensor (1). Within a device which realizesthe technological process with the luminous manifestation the instruction for the

beginning of a given technological process is detected and on the basis of this instructionthe activation light (3) lights up. This activates the optical sensor (1) by means of theactivation light (3) before the optical sensor (1) detects the luminous manifestation of thetechnological process itself. The activation light (3) can be a simple infrared LED diode.The advantage lies in the fact that the protective device itself does not have to bemodified in any way and its reaction time can be shortened to zero, or negative reactiontime can be achieved since we use time passing during the initiation of the technologicalprocess before the appearance of the luminous manifestation for the darkening.
