摘要
The operation of light-emitting diode (LED) devices has identified a number of peculiar features of the angular distribution of light intensity. The use of several light-emitting diodes results in an unevenly bright light-emitting surface of a lighting device. When lighting devices operate under vibration conditions, certain circumstances may occur when highlight or lowlight areas appear and are continuously observed on screen. The authors have simulated model conditions of dark screen areas occurred as applied to the light flux being formed by light-emitting railway headlights. (C) 2017 The Authors.
