Garden lighting is all about ambience so its crucial to ensure that there is no glare created from lights particularly fittings that are close to the house or in areas where you will be walking past on a regular basis. Various methods have been developed in different countries for assessing the risk of direct glare from a lighting system, e.g. The IESNA full cutoff, cutoff, and semicutoff designations limit the intensity values in the glare zone. It is subjective, and sensitivity to glare can vary widely. The UGR (Unified Glare Rating) process is used to evaluate and limit the direct discomfort glare in indoor areas. Glare is caused by the reflection of light off of surfaces and is a primary cause of eyestrain. Glare has always been a relevant topic, especially since electric light levels began to increase. In the table, the source intensity applies to each source in the potentially obtrusive direction, outside of the area being lit. Glare can be dangerous and distracting and occurs during the day and night in a variety of ways. Measures to control glare include light shelves, louvers, blinds, fins, and shades… Glare control is required for each window.” SolarBlade has directly answered the requirements of Daylighting by the USGBC. Various kinds of Industrial Lights and their usage lighting is among the significant contributors to operating cost of any organization. Precision, Glare-Free Optics. Dome illumination is used most often to inspect shiny, curved, or bumpy surfaces. The control of light spillage has been largely accomplished in the past by the use of glare shields built into the light source or the luminaire which are intended to limit the light being cast to those areas intended. ; reduction in contrast by scattering light in particles in the air, as when the headlights of a car illuminate the fog close to the vehicle, impeding vision at larger distance. Control – Lighting systems with automatic control allows for quickly repeatable testing procedures. To get the most out of any LED, and to restore brightness, we created GLARE CONTROL. Glare is a visual sensation caused by excessive and uncontrolled brightness. In architecture, glare is desirable when a designer wants to cause extreme contrast that exhilarates the visual experience. Another way to fix the glare issue of the light bulbs is that we can tilt the object a little bit to avoid looking at the surface that is totally parallel to the ceiling.
