A light distribution unit and a light distribution component

Abstract

The invention provides a light distribution unit and a light distribution assembly. The light distribution unit is characterized by comprising light sources, a light source base plate and a lens main body; the light sources are fixed to the light source base plate; the lens main body is arranged on the light sources in a covering mode, fixed to the light source base plate and in a rotational symmetric shape along a rotating shaft of the lens main body and comprises a center emitting part and a glare limiting part which are continuously connected; and the glare limiting part surrounds the center emitting part and is used for deflecting light rays emitted by the light sources to the positions outside the second beam angle threshold value, the beam angle of the light rays is larger than the first beam angle threshold value, and the second beam angle threshold value is larger than the first beam angle threshold value. According to the light distribution unit and the light distribution assembly which are provided by the invention, the stray light rays which do not meet the anti-glare requirements can be deflected to the invisible areas through the glare limiting part, so that the glare influence caused by the stray light rays is avoided, and the influence of the stray light rays on the predetermined round light spot shape also can be avoided.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a light distribution unit and a light distribution assembly. Background technique [0002] With the continuous improvement of living and working standards, people have higher and higher requirements for the comfort of the space light environment. The quality of the light environment directly affects people's visual organs and psychological comfort. Among them, glare has a greater impact on people's visual comfort and easily causes people's visual fatigue. [0003] Glare is an undesirable visual environment that produces discomfort, or reduces the ability to see primary objects, or both. Caused by inappropriate luminance distribution in the field of view, disparity in luminance, or extreme contrast in space or time. UGR is by far the best model for simulating human perception with mathematical methods, so the lens can effectively reduce the value of UGR, which is the most effectiv...

Problems solved by technology

UGR is by far the best model for simulating human perception with mathematical methods, so the lens can effectively reduce the value of UGR, which is the most effective control of glare. However, a single lens often produces a lot of glare when it is used with multiple light sources This part of the light is mainly reflected in the stronger light intensity on one side of the beam angle of 60° to 90° compared with the single lens and single light source, and the resulting space simulation glare will be stronger
