摘要(Abstract)：

以分段线性驱动HV-LED灯具的照度输出波形为研究对象,从幅度、梯度、边界和时间四个方面提出9种指标参数,用于表征灯具的照度变化特征。以四段式线性驱动光源模组为实验研究对象,使用LFA-2000型光源频闪测试仪采集光源的照度变化数据,分析变化特征。研究结果可以作为分段线性恒流驱动HV-LED灯具质量检测、故障诊断的指标依据。
The illumination output waveform of HV-LED lamps with segmented linear driver was studied.The nine parameters were proposed from four perspectives including amplitude,gradient,boundary and time,which can be used to characterize the illumination of HV-LED lamps. Taking one light source module driven by the four-segment linear driver as the experimental object,the illumination data of the light source were collected by the LFA-2000 light source stroboscopic tester,and the change characteristics were analyzed. The research results can be used to quality testing and fault diagnosis of HV-LED lamps.
