Stand for definition of stability optically transparent surfaces on the impact of natural and anthropogenic factors

Significant differences of the operating conditions of the lighting devices for different purposes lead to the necessity to improve not only their design, but also to the optimization of the technological process of their manufacture. To identify as a result of field tests of the most critical natural and man-made factors affecting the reliability of lighting devices required lengthy and costly trials, for example, on the track. Such tests it is advisable to spend on the stand. We propose a special design of the stand allows to change the mode of exposure of the required factors, and their combinations, as well as time sequence and duration of their impact.
