What is glare recovery time

Glare limitation

Glare limitationA complex of measures that serve to prevent, eliminate or reduce glare in order to counteract a reduction in visual performance, performance and well-being as well as premature fatigue.

The B. is a central task of lighting technology because glare can significantly impair visual comfort, which is characterized by high illuminance levels, spatial and temporal uniformity of illuminance levels, correct shading, a corresponding light color, etc.

The aim of B. is to avoid direct glare from lamps and luminaires, reflected glare and glare from the surroundings. Since the glare effect depends on the luminance contrast, the angular extent of the glare source and its position in the field of vision, the following measures can, for example, lead to: Limiting the contrast in the field of vision, e.g. by combining workplace and general room lighting; Appropriate placement of the lighting in relation to the workplace to avoid reflected glare and to reduce the effective size of the glare source, e.g. line-shaped glare sources must always be installed in the main line of sight; Reduction of the luminance of the lamps through the use of opaque and internally frosted glasses as lamp bulbs; Reduction of the luminance of luminaires by installing screens, diffuse diffusing covers and lampshades Increase in the average luminance of the field of view.

Measures for B. are also necessary in road traffic. It can take place through the design of the lanes (separate) and their surfaces, through appropriate street and tunnel lighting and, above all, through the correct design of the lighting equipment on motor vehicles (headlights, taillights, etc.).
