With the continuous renewal of light source products, people are paying more and more attention to healthy lighting. The detection of lighting quality is an important guarantee of healthy lighting, especially the detection of lighting quality parameters such as intensity, flicker frequency and flicker proportion. Aiming at health lighting, design a kind of lighting lamps and lanterns lighting quality detector based on STM32, silicon photocell chosen as the photoelectric sensor, through the current voltage conversion and low pass filtering to extract the signal intensity of the light, through band-pass filter to extract the stroboscopic signal, using the stroboscopic signal envelope detection circuit as a picture, using the stroboscopic signal frequency discriminator circuit. STM32F103RCT6 microcontroller is used as the core processor to analyze and process the information, and obtain the quality parameters such as light intensity, flicker frequency and flicker proportion. The main advantages of the system are that it can detect the multi-parameter quality of lighting lamps online, with simple structure, small size, low cost and good stability. It can be used to detect the lighting quality of household lighting lamps, and help people screen out better lamps and achieve healthy lighting. After the experiment, the system can accurately detect whether the household lighting on the market is qualified, the detection accuracy can reach more than 99%. It can detect whether the light source is healthy and provide a reference method for detecting whether the light source is safe.
