Abstract (en)
[origin: EP2584874A1] The lamp (100) has several sensors (20) for detecting a sensor signal representing a luminance of an illumination or a light output of the LED light source (10). The deviation of an operational function of the LED light sources is detected based on comparison of the sensor signals. The sensors are arranged in an edge area of a light radiation region. The sensors are provided with photo-diodes and photo-resistor. Independent claims are included for the following: (1) a light management system; and (2) a method for detecting deviation of operational function of LED.
