Description

Display hanging lamp

Technical Field

The utility model relates to a lamp decoration field, in particular to display hanging lamp.

Background

Glare refers to the condition of vision in the field of view due to unfavorable luminance distributions, or extreme luminance contrast in space or time, so as to cause visual discomfort and reduce the visibility of objects. The visual field produces a sense of brightness that the human eye cannot adapt to, and may cause aversion, discomfort or even loss of visibility. An excessively high luminance occurs in a local place in the visual field or an excessively large luminance change occurs in front and rear. When a computer office worker stares at a display for a long time, the display and the light below the front of the display are dim and are contrasted with the bright light of the display, so that the glare of the display is easily caused, and the visual fatigue is further accelerated. In addition, when the desk lamp or other lamps are used for lighting, the lamp light can be reflected by the display to cause glare, and the direct-view desk lamp or other lamps can also cause glare. In the past for a long time, the visual health of people is seriously influenced.

Therefore, how to solve the problem of glare of the display is a technical problem to be solved by those skilled in the art.
