초록

The device for a life test of a railway vehicle headlight LED was produced and design. The manufactured life test apparatus has a structure in which the illuminance of a plurality of samples is measured by a single illuminance measuring apparatus. In order to measure the illuminance of the life test apparatus, all the samples were turned off, and then the individual power was supplied sequentially to select the measurement method. However, this illumination measurement method has a phenomenon in which the measured illuminance differs from the normal illuminance when the sample is turned off and then supplied again. In this paper, we investigate the cause of the difference in illuminance and studied the illuminance measurement method to solve it.
