To my question to answer, Led advertising lights to what extent can you not look directly at?Who is the Henan University Jinming campus dormitory Huayuan residential district, there is a door to the stationery LED lights at night can make people do not know is not open, I often use the computer, with eye fatigue or other what reason, every time I see that the lights are people eyes ache, head with a needle under the same feeling at that time, instantaneous memory disappears, so I want to put this issue into a physical question to answer. Design LED light intensity and other data, as well as the degree of tolerance of the human eye, you can find your own information, set your own.
Glare interpretation:Glare (glare) refers to the visual conditions in visual field due to inappropriate luminance distribution, or extreme brightness contrast in space or time, resulting in visual discomfort and reducing object visibility.
LED advertising lights too bright, uncomfortable, that is, light pollution, glare. Glare should be avoided as much as possible in lighting design.
Visual light produced by the human eye can not adapt to the light feeling, may cause disgust, discomfort, or even loss of vision. Excessive brightness or excessive brightness changes occur in a certain part of the field of view. Glare is one of the important causes of visual fatigue.
