Domain.
Background technique
Dazzle is mainly as caused by light source position and the angle of viewpoint.The high light source of brightness, produces by reflection
The high light of raw height or strong brightness contrast will allow spectators to generate dazzle.Dazzle in exhibition environment is once
The dazzle of secondary reflection generation is also passed through in transmitting dazzle.Dazzle not only will cause visual inadaptable sense, and strong
Dazzle can also damage vision or even induce blindness.For showing for luminous environment, control dazzle is critically important.Vision in dazzle city one
Condition, the formation of this condition are by Luminance Distribution is inappropriate or the amplitude of brightness change is too big or space, exists on the time
Extreme comparison so that causing abilities that are uncomfortable or reducing observation important objects, or generate both phenomenons simultaneously.Dazzle is
A kind of serious light pollution causes vision to interfere pedestrian such as the dazzle that the glass curtain wall of modern city high-lager building reflects,
The normal rest of surrounding resident is influenced, the dazzle that road curb lamp light decoration and nightscape lighting light source generate will cause the burst of people
Property Whiteout and eyesight illusion, the visual field of driver can be covered in moment, it is easy to cause traffic accident.
21 century is the information-based epoch, and the application of computer has penetrated into different social sectors, and becoming can not
