Abstract:
In a method and a device for detecting the light power emitted by an LED light source, the LED light source is driven with a drive signal corresponding to a binary code. The light emitted by the LED light source is detected by means of a sensor system. The output signal of the sensor system is evaluated in a control and regulating unit. The LED light source is driven with a binary code having an irregular bit sequence.
