Patent attributes
A head protection device has a distance-measuring device with a spatial directional characteristic, a light beam generation device as well as at least one control unit. The distance-measuring device is configured to determine distance information relative to a focusing range of the spatial directional characteristic and to provide the determined distance information to the control unit. The light beam generation device is configured to generate a light beam in the direction of the focusing range. The control unit provides a control signal, which indicates a request for a brightness modulation frequency of the light beam as a function of the distance information, to the light beam generation device on the basis of the distance information in a first operating mode.
