CIE Position Statement on Non-Visual Effects of Light - 2nd Edition

CIE Position Statement on Non-Visual Effects of Light - 2nd Edition On October 3rd, CIE released their new position statement on non-visual effects of light, entitled "Recommending Proper Light at the Proper Time" 2nd edition. As non-visual effects are becoming more attention nowadays, confusion and uncertainties on this topic are still high in the lighting community. Much research has been done but even more research is necessary. CIE has recognized this relevant topic and already initiated an independent workshop of leading scientists in the field of quantifying light for non-visual effects in Manchester in 2013 (CIE TN 003:2015 (CIE 2015)). The CIE issued an international standard, CIE S 026:2018 (2018), that defines a system for metrology of optical radiation for light-induced responses that can be elicited by ipRGCs (ipRGC-influenced light (IIL) responses).

Market Entry in Saudi Arabia – with Obstacles

Market Entry in Saudi Arabia – with Obstacles The international market for lighting products is getting more complicated for manufacturers. After the use of product tests by China and Russia as a hurdle, Saudi Arabia is now demanding CB Certificates and an energy label with a two-year validity period for lighting products. Hans Laschefski, Industrie Marketing Manager Lighting EMEA at UL, shows why and how external testing laboratories can help overcome these hurdles through forward planning. Read more »

Horticultural Lighting - The Root to International Standards

Horticultural Lighting - The Root to International Standards Plants have evolved to make the most of the conditions in which they naturally grow. For some plants, this environment will be fully supportive; it may be less so for others. In general, the plant with the fully supportive conditions will predominate in the absence of external intervention. Humans have changed plants over the centuries, selectively growing the plants that provide maximum perceived benefits in terms of color, smell, yield and, perhaps more recently, nutritional value. For most of our evolution, we have had to make use of the environmental conditions available. The desire for cheap food, all year around, and attempts to minimize "food miles" has increased the move towards providing totally constructed growing environments. Read more »

"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.

CIE Research Strategy in Metrology for Advanced Photometric and Radiometric Devices

CIE Research Strategy in Metrology for Advanced Photometric and Radiometric Devices Photometric devices are devices that measure optical radiation and which are designed with a very specific spectral response. Most commonly, illuminance meters and luminance meters are used to measure the illuminance and luminance distributions in the field. These are relatively simple devices, characterized by a specific input optics according to the required task and a filter to make the spectral response of the instrument match the spectral luminous efficiency function of the human eye (typically V(λ) for photopic vision). In testing laboratories, integrating spheres are used to measure the total luminous flux of a light source and goniophotometers are used to measure luminous intensity distributions, total luminous flux and partial luminous flux. These devices are all well understood, and several CIE technical reports are available that give guidance on their characterization and calibration [1][2][3][4]. Read more »
