Abstract

The invention discloses a method for analyzing the strobe of an electric light source based on spectral analysis, comprising: selecting a lamp to be detected, collecting spectral distribution data; calculating a spectrum-to-flicker ratio, comparing the spectrum-to-flicker ratio with a signal-to-noise ratio of a spectrometer, and initially judging whether there is strobe, if the conditions are notmet, continuing the analysis; calculating a relative luminous flux corresponding to no less than 50 sets of spectral distributions; fitting a function expression to the relative luminous flux R(t), calculating a flicker frequency f and the percentage of a visual flicker, determining the strobe of a luminaire according to the flicker frequency f and the percentage of the visual flicker, outputtingthe flicker frequency and the percentage of the visual flicker of the luminaire to complete the analysis. According to the method for analyzing the strobe of an electric light source based on spectralanalysis, a quantitative analysis on the strobe of the electric light source can be done only by using the most basic and most popular spectrometer for optical research and analysis, and the relevantcalculation parameters and the physical meaning of the process are clear.

Description

technical field [0001] The invention relates to the field of health lighting, in particular to a method for analyzing the frequency flicker of an electric light source based on spectral analysis. Background technique [0002] The strobe of the electric light source refers to the phenomenon that the light emitted by the electric light source changes rapidly and repeatedly over time, making the light source beating and unstable, and causing the luminous flux of the light source to fluctuate. The main reasons for the flickering of electric light sources are: low power supply frequency of the light source, large voltage fluctuations, and the principle of light emission of the light source. Current research shows that the main hazards of stroboscopic electric light sources are: illusions cause industrial accidents; induce epilepsy, migraine, nausea, etc. in photosensitive people; damage the glasses of young people and cause myopia. [0003] As people pay more attention to the he...
