Description
Summary:INTRODUCTION: The contents of the CIE Technical Report draft - Photometry of Flashing Lights - from CIE TC2-49 will be presented with special focus on measurement of LED warning lights. METHODS: Modified Allard method is to be recommended by CIE for all types of flash waveform. The method will be explained in comparison with traditional Blondel-Rey equation and Form Factor method. RESULTS: Some results of vision experiments from an old literature, for train of pulses in different intervals, are shown to demonstrate that Modified Allard method works best. DISCUSSION: The limitation of this recommended methods and future needs for research will be discussed.
