1. A handrail disinfecting device, comprising:
at least one housing; and
a plurality of light-emitting diodes having a main light cone axis, which light-emitting diodes can emit germicidal electromagnetic radiation in the region of their light cone,
wherein the housing has an entry side and an exit side opposite the entry side for a continuous handrail of a passenger transport installation,
wherein a pass-through segment for the handrail, which segment is divided into at least two sectors, is present in the housing between the entry side and the exit side;
wherein the sectors are arranged one behind the other in the longitudinal extension of the pass-through segment;
wherein at least one light-emitting diode is arranged in the first sector, the main light cone axis of which diode is oriented substantially orthogonally to a first plane; and
wherein at least two light-emitting diodes are arranged in the second sector, wherein the main light cone axis of at least one light-emitting diode is oriented substantially orthogonally to a second plane and the main light cone axis of at least one light-emitting diode is oriented substantially orthogonally to a third plane, and
wherein the second plane and the third plane are arranged in parallel with the longitudinal extension of the pass-through segment and so as to be mutually inclined at an angle of 100° to 160°,
and wherein the handrail disinfecting device has at least one guide roller, by means of which guide roller a handrail of a passenger transport installation can be guided through the housing in the pass-through segment in a defined position in relation to the light-emitting diodes.
