Project Connected Home over IP Connectivity Standard Developing Into Reality

When we set out in December 2019 to create a unifying standard for the smart home industry, there was naturally a lot of excitement — and of course, questions. Would this global consortium truly be able to bring this new standard to market? How long would it take? What products would actually emerge? Would we be able to pull off our promise to unify a fragmented industry under a single connectivity standard that would help companies focus on creating experiences over "plumbing"? Read more »

IES and IUVA Collaborate to Publish ANSI Standards for Measuring Ultraviolet C-Band (UV-C) Sources Used for Disinfection

The Illuminating Engineering Society (IES, est. 1906) and the International Ultraviolet Association (IUVA, est. 1999) have partnered to assemble experts in the measurement of ultraviolet C-band emissions (UV-C) to develop American National Standards for the measurement and characterization of UV-C device performance. UV-C devices for healthcare and personal care have proliferated in recent years, particularly during the COVID-19 pandemic, despite the absence of standards to enable accurate measurements and comparisons of the products. Through this partnership IES and IUVA aim to cooperatively promote awareness of and improve the application of ultraviolet "disinfection" technology in the healthcare system, initially through the development of standardized methods of measurement of ultraviolet "disinfection" products including UV lamps, luminaires and lighting/radiating systems, utilizing both discharge (e.g. low-pressure mercury and xenon) and solid-state (e.g. light-emitting diode) technologies.

New CIE Technical Report: Optical Measurement of LED Modules and Light Engines

LED modules and light engines represent a wide range of very different products with unique physical properties. Thus, they can neither be treated as single LED packages (where measurements refer to a specific junction temperature of a single LED or the average of a single die, multiple-junction LED) nor as complete lamps or luminaires (where measurements refer to the ambient temperature).

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).

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 »

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

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

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.
