Abstract
The invention relates to the field of photoelectric detection in a lighting environment, and in particular to a LED light source flickering detector. An optical signal automatic capturing module, based on an optical signal detected, generates a corresponding electric signal, transmits the electric signal to a data processing module for time-domain and frequency-domain analysis so as to obtain the characteristics of the optical signal. A rotation apparatus enables a photoelectric detector to move in 2 planes which constitute an angle therebetween in a manner that the photoelectric detector conducts full-circle movement in a first plane and conducts quarter-circle movement in a second plane, such that the photoelectric detector can rotate 180 degrees in a 3D space so as to automatically capture a strongest optical signal in all direction from the LED light source. During detection, the detector automatically performs detection and conducts data processing, obviates the need for the presence of measurement workers in the field, and can prevent the light environment in the measurement field from being damaged, thus increasing detection efficiency and precision.
