At the 2017 Strategies in Light conference, Dan Ryan of Acuity Brands Lighting examined lighting disruption posed by LED technology and the internet of things (IoT). He said a good starting point to predicting what will happen next in the lighting industry is to look at changes in similar industries, such as electronics and computing. READ MORE

The lighting industry continues to explore the potential for lighting solutions to benefit and optimize human health. Studies indicate light has physiological effects that go beyond vision. In recent years, the industry has focused on the effect of light on the human circadian system and how electric lighting choices can affect circadian health. Light and circadian rhythms

At the 2017 Strategies in Light conference, Robert F. Karlicek, Jr., spoke about creative destruction in the lighting industry brought on by LED technology and the internet of things (IoT). Karlicek is a professor and director for the Center for Lighting Enabled Systems and Applications at the Rensselaer Polytechnic Institute, Troy, N.Y.

Networked lighting controls are intelligent and programmable systems in which devices communicate to enact control strategies. Despite the extraordinary potential of these systems, adoption has been inhibited by difficulty in reliably projecting energy savings, unfamiliarity among specifiers and, notably, contractors, interoperability and complexity issues and cost.

In commercial building applications, dimming either is used to support visual needs (usually in response to manual input) or to save energy (usually in response to automatic input). As the majority of LED products are dimmable, the proliferation of LED lighting has increased availability and use of dimming.

The ASHRAE/IES 90.1 energy standard provides legal jurisdictions with a model commercial building energy code. The 2013 version is the national energy reference standard recognized by the U.S. Department of Energy. The International Energy Conservation Code recognizes 90.1 as an alternative compliance standard.

Organic LED (OLED) is a solid-state lighting technology with strong potential for architectural lighting. The LED is a compact, directional point source. Shielding prevents glare, while heat sinking removes internal heat. In contrast, OLED is a flat (less than 1/8-inch thick), diffuse area source. Depending on the product, one can view it directly without glare. READ MORE
