PROJECTION DEVICE FOR PROJECTING AT LEAST ONE IMAGE ONTO A PROJECTION SURFACE AND CORRESPONDING METHOD FOR OPERATING A PROJECTION DEVICE

摘要

The invention relates to a projection device (10) for projecting at least one image onto a projection surface (30), comprising: at least one laser device (12) for emitting radiation (14) for the image projection; at least one sensor device (18), wherein the sensor device (18) is designed to ascertain a hazardous situation for a person (24) due to the radiation (14) of the at least one laser device (12); and a control device (22), which is coupled to the at least one laser device (12) and the at least one sensor device (18), wherein the control device (22) is designed to modify at least one operating parameter of the at least one laser device (12) when a hazardous situation for a person (24) is ascertained, wherein the sensor device (18) is designed and arranged to detect radiation (20) of the at least one laser device, (12), said radiation being reflected by the projection surface (30). The invention further relates to a corresponding method for operating a projection device (10).
