Helmet light, protective helmet with a helmet light and method for operating a helmet light

A helmet light for fastening to a protective helmet, wherein the helmet light comprises a control controller and a sensor unit with a head recognition sensor, and wherein the helmet light can be switched into several operating modes and states,

• wherein the sensor unit is adapted to detect sensor data from the at least one head recognition sensor, to process them and to send them to the control controller as processed head recognition sensor data,
• wherein the control controller is adapted to receive the processed head recognition sensor data and to switch the helmet light between the several operating modes and states based on the processed head recognition sensor data.

A method for operating a helmet light which can be fastened to a protective helmet, wherein the helmet light comprises a control controller and a sensor unit with a head recognition sensor unit,

• wherein, through the sensor unit, sensor data from the at least one body temperature sensor are detected and processes and sent to the control controller as processed head recognition sensor data,
• wherein, through the control controller, the processed head recognition sensor data are received and the helmet light is switched between the several operating modes and states based on the processed head recognition sensor data.
