摘要：
A portable electronic device includes a light source, which includes at least one luminescence diode and emits light during operation. The portable electronic device also includes a device for detecting an object in the beam path of the light emitted by the light source during operation. The device is designed to reduce the luminous flux of the light emitted by the light source during operation if the object is identified for a minimum duration within a minimum distance from the light source in the beam path.
