Abstract

Disclosed are a lighting source detection machine and a lighting source detection method. The lighting source detection machine includes a base, a wide-area dynamic optical detection device, a processing device, a driving conveyor and a sorting device, wherein the wide-area dynamic optical detection device includes a plurality of solar cells, and the driving conveyor includes a feeding arm and a conveying belt. The detection method includes that the feeding arm draws a lighting source of an illustrated LED (light-emitting diode) and transfers the lighting source on the conveying belt, the conveying belt conveys the plurality of lighting sources to be detected to detection positions on the base and supplies power to drive the lighting sources to shine, the solar cells receive optical signals, transfer the optical signal into electric signals, and transmit the electric signals to the processing device to perform Fourier transform, Fourier reverse transform after noise signals are removed, and stroboscopic and stroboscopic effect detections, and finally the processing device drives the sorting device to sort every LED.

Description

Technical field

[0001] The invention relates to a detection of stroboscopic and stroboscopic effects of an illumination light source, in particular a detection machine and detection method for an illumination light source.

Background technique

[0002] With the evolution of science and technology, the use of LEDs as lighting equipment continues to innovate, and product performance continues to be continuously improved. However, due to unstable power supply, the luminous intensity of the light source changes with time, the circuit design and the unreasonable design of the lighting device. The emitted light produces periodic and non-periodic flickering of luminous intensity; and this kind of flicker, once in the frequency range that can be perceived by human vision, will cause discomfort, fatigue, and even damage to rotating objects due to the flickering of the light source. Misjudgment of the speed of rotation can lead to accidents and injuries. Therefore, when the fluct...
