Description

Wing formula lens panel lamp

Technical Field

The utility model relates to a wing type anti-dazzle panel lamp, and belongs to the technical field of lamps.

Background

The research finds that: people who work and live in a light polluted environment for a long time can have retina and iris damaged to different degrees, the vision is rapidly reduced, and the incidence rate of cataract reaches 45%. The myopia rate of high school students in China reaches more than 60%, and part of reasons are eye habits, and the pollution to the visual environment is also one of the main reasons.

The commission internationale de l' eclairage (CIE) is used to measure the psychological parameters of the subjective reaction of light emitted by a lighting device in an indoor visual environment to discomfort to the human eye. Glare is defined as a visual phenomenon due to an unfavorable luminance distribution or range of luminance in the field of view, or the presence of extreme contrast, so as to cause an uncomfortable feeling or reduce the ability to view details or objects. Conventionally, glare is what is commonly referred to as "dazzling" which causes a person to feel dazzling, causing pain and tearing or reduced vision, and even loss of visibility due to inadequate vision.

General causes of glare can be summarized as follows: 1. the brightness of the light source (the higher the brightness, the more noticeable the glare); 2. the position of the light source (the closer to the line of sight, the more noticeable the glare).

Discomfort glare in rooms or places commonly used in industrial and public buildings should be evaluated using Unified Glare Rating (UGR).

UGR values 28, 25, 22, 19, 16, 13, 10, and the like. 28 is just unbearable, 25 is uncomfortable, 22 is just uncomfortable, 19 is a comfortable and uncomfortable threshold, 16 is just acceptable, 13 is just dazzled, and 10 is no glare.

The illuminance standard of GB50043-2004 mostly adopts UGR values of 25, 22 and 19.

Incapacitating glare is glare that reduces visual efficacy and visibility, while it is also often accompanied by discomfort. The stray light of a high-brightness light source in the visual field enters eyes and is scattered in eyeballs, so that the definition and the contrast of an object on a retina are reduced.

Incapacitation glare is measured as the ratio of the visibility of a job at a given lighting installation to its visibility under reference lighting conditions, called the incapacitation glare factor (DGF).

Discomfort glare (discomfort glare), also known as "psychological glare", is directed to causing visual discomfort without causing glare that reduces visibility.

The two kinds of Glare are so-called ugr (unified Glare rating), i.e. the unified Glare value, and are one of the main contents of the illumination quality evaluation in the illumination design. The two kinds of glare can appear simultaneously or singly, and the same UGR is not only a visual puzzle, but also a puzzle in design and application.
