forming the light pulse sequence with a disorientation sequence in which alternately, one after another, a plurality of dazzle pulse sequences with a plurality of dazzle pulses are emitted to bring about a disorienting effect on a target person and a plurality of dazzle pauses without the dazzle pulses are emitted, a period duration of one sequence having a dazzle pulse sequence and a subsequent dazzle pause being at most 250 ms; and/or forming the light pulse sequence with a disorientation sequence in which a plurality of dazzle pulses is emitted to bring about a disorienting effect on a target person, and the light pulse sequence furthermore contains a pre-sequence preceding the disorientation sequence in which stimulus light, which is perceptible by the target person, is emitted having a luminance of at most 1×103 cd/m2 to draw the target person's attention and thus shift the target person's line of sight towards the dazzling element. ### Claim 2 (depends on 1) The method according to claim 1, which further comprises forming the light pulse sequence with a disorientation sequence in which a plurality of dazzle pulses are emitted to bring about a disorienting effect on a target person, wherein the dazzle pulses each have a luminance of at most 1.6×106 cd/m2. ### Claim 3 (depends on 1) The method according to claim 1, which further comprises forming the light pulse sequence with a disorientation sequence in which a plurality of dazzle pulses are emitted to bring about a disorienting effect on a target person, wherein the dazzle pulses each have a pulse slope in a range from 0.5×105 cd/m2·ms to 2.0×105 cd/m2·ms. ### Claim 4 (depends on 1) The method according to claim 1, which further comprises forming the light pulse sequence with a disorientation sequence in which a plurality of dazzle pulses are emitted to bring about a disorienting effect on a target person, wherein the dazzle pulses each have a pulse width in a range from 20 ms to 50 ms. ### Claim 5 (depends on 1) The method according to claim 1, which further comprises emitting at least one stimulus pulse emitted in each of the dazzle pauses of the disorientation sequence without bringing about the disorienting effect on the target person. ### Claim 6 (depends on 1) The method according to claim 1, which further comprises forming the light pulse sequence with a disorientation sequence in which a plurality of dazzle pulses are emitted to bring about a disorienting effect on a target person, wherein the dazzle pulses have such pulse widths and light intensities that they generate, at a defined distance from the dazzling element, an irradiance below a maximum permissible exposure of the target person. ### Claim 7 (depends on 6) The method according to claim 6, which further comprises capturing distances between the dazzling element and the target person and the defined distance is determined in dependence on the distances captured. ### Claim 8 (depends on 7) The method according to claim 7, wherein in a case when a plurality of dazzling elements are used, the light pulse sequence emitted by the at least one electronic light-emitter is adapted to distances from target persons captured by other ones of the dazzling elements. ### Claim 9 (depends on 6) The method according to claim 6, wherein the defined distance is an expected minimum distance between the dazzling element and eyes of the target person. ### Claim 10 (depends on 1) The method according to claim 1, which further comprises emitting the light pulses of the at least one optical emitter as collimated light beams. ### Claim 11 (depends on 1) The method according to claim 1, which further comprises using a plurality of dazzling elements, the light pulse sequence emitted by the at least one electronic light-emitter is adapted to the light pulse sequences emitted by the at least one electronic light-emitters of other ones of the dazzling elements. ### Claim 12 (depends on 1) An electronic dazzling element, comprising: at least one optical emitter having at least one electronic light-emitter for emitting light pulses; and a controller for controlling said at least one electronic light-emitter of said at least one optical emitter, said controller is configured for performing the method for operating the electronic dazzling element according to claim 1. ### Claim 13 (depends on 1) The method according to claim 1, wherein each of the dazzle pauses is at least 50 ms.
