摘要
为了便于广大基层质检人员工作,提出了一种仅利用光谱仪即可定量研究光电源频闪的方法。该方法无需使用光源频闪测试仪、数字示波器等设备,仅需利用普通光谱仪采集一段时间内被测电光源的瞬态光谱数据,通过光谱分析即可定量研究电光源频闪。通过对明视觉光谱光效率函数的高质量拟合和对被测电光源的相对光通量计算及其8阶傅里叶拟合,分别计算并分析了白炽灯、LED灯丝灯、碘钨灯三种电光源的闪烁百分比、频闪深度和频率,并与LFA-2000型光源频闪测试仪的测量结果进行比较。结果表明:该方法计算得到的三种电光源的闪烁百分比、频闪深度和频率平均相对误差分别为4.93%、4.89%和10.17%,对应的最大相对误差分别为8.31%、7.95%和14.22%。在被测光源频闪频率不大于200 Hz时,该方法准确、可行,可为相关仪器设备的开发及人工照明设备研究和质检等提供参考。
Abstract
This study develops a spectral analysis method to provide a convenient method for quantitatively analyzing flicker of electric light sources for mass basic quality inspectors. This method only requires the use of transient spectral data of electric light sources measured by a common spectrometer within a certain period of time, instead of using light source stroboscope and digital oscilloscope. By the means of high-quality fitting of the spectral luminous efficiency function of photopic vision, calculation of relative light flux, and eight-step Fourier fitting, the scintillation percentage, stroboscopic depth, and stroboscopic frequency of incandescent, LED filament, and iodine tungsten lamps are calculated and analyzed, and the test results are compared with data measured by an LFA-2000 light source stroboscope. The results show that the average relative errors of scintillation percentage, stroboscopic depth, and stroboscopic frequency for these three types of electric light sources calculated by this method are 4.93%, 4.89%, and 10.17%, respectively, and the corresponding maximum relative errors are 8.31%, 7.95%, and 14.22%, respectively. The method is proven to be correct, feasible and accurate when the stroboscopic frequency of the measured light source is less than 200 Hz. This method can provide references for the development of related instruments and equipment, as well as the research and quality inspection of artificial lighting equipment.
