"Glare" Is to Light as "Noise" Is to Sound - CIE Research Roadmap on Glare

"Glare" Is to Light as "Noise" Is to Sound - CIE Research Roadmap on Glare Glare has always been a relevant topic, especially since electric light levels began to increase. With high intensity light sources like LEDs, the problem culminated in the last few years. CIE addresses this topic in its recent publication CIE 205:2013: "Review of Lighting Quality Measures for Interior Lighting with LED Lighting Systems". Furthermore the Joint Technical Committee JTC 7 is still working on this topic. A short overview on the topic and CIE's activities is presented. Read more »

Visual Appearance: Perception, Measurement and Metrics

Visual Appearance: Perception, Measurement and Metrics Visual appearance is one of the most critical parameters affecting customer choice and needs in products. We use the response from our visual sense to process the complex patterns of light around us into objects, space, location and movement, and from that information, we make judgments leading to a particular course of action. For example, how we perceive the visual appearance of a product may cause us to buy it, reject it or even write to complain about it. We may choose to buy a particular food because its appearance suggests freshness. Our choice of car may have been influenced because its glossy appearance made us think of quality and prestige. Alternatively, we may reject a particular surface finish because its appearance suggested poor quality and the presence of defects. All of these examples represent judgments made on appearance.

Adaptive, Dynamic and Intelligent Lighting

Adaptive, Dynamic and Intelligent Lighting Previously, most lighting applications were designed to ensure suitable visual conditions, to support the most demanding visual task anticipated, whilst also taking into account requirements to provide adequate levels of visual comfort and aesthetics. In most cases this was a static lighting solution because the options to change light levels, luminance distribution, or light source spectrum were limited. Tasks, occupants, and needs change from time to time, making control over the lighting desirable, if unattainable. Advanced LED and controls technology make the unattainable possible; now, the key questions are also for CIE how to define the user needs for various applications and how best to set up lighting systems to be adaptive and intelligent in response.

CIE Considers the "Good and Bad" of Light

CIE Considers the "Good and Bad" of Light Light, and the wider optical radiation spectrum (ultraviolet and infrared radiation), provides us with many benefits. However, too much may be harmful and too little may mean we cannot carry out our daily activities, or may indeed compromise our well-being. Division 6 of CIE, Photobiology and Photochemistry, is responsible for developing action spectra for the effects of optical radiation on people, as well as flora and fauna. John O'Hagan, Luke Price and Luc Schlangen, respectively, Division 6 director, Division 6 secretary and chair of the Joint Technical Committee (JTC) 9, explain the work done to determine the balance between risk and benefit from exposure to optical radiation.
