LAMP AND SYSTEM WITH WALL-TYPE RADIATION FIELDS FOR PREVENTING OR MINIMISING THE SPREAD OF PATHOGENS IN INDOOR AIR

The invention is directed to a system for preventing or minimizing the spread of viruses, and to the prevention or minimization of the spread of viruses in indoor air, including one or more radiation sources (10) in a room which divide the room into smaller segments using UV-C light walls, a sensor system for detecting a movement or a presence of one or more persons (P) in the room, and a controller (16) that is designed to at least partially switch the one or more radiation sources (10) on or off as a function of at least the presence of the person (P).According to the invention, the one or more radiation sources (10) are designed to generate a wall-type radiation field (10b) that acts as a UV-C wall, so that the room or rooms is/are divided into smaller room segments, which prevents or minimizes the spread of viruses due to the fact that the viruses are deactivated by the UV-C light, and the controller (16) is designed to at least partially switch off the radiation source (10) in question if the movement data detected by the sensor system indicate a likelihood that one of the persons (P) would like to pass through the radiation field (10b) in question.
