Lighting Design

LED area and roadway lighting promises energy and maintenance cost savings, but the longevity of the LED light source presents a hitch. Traditionally, luminaires are cleaned upon relamping. If relamping does not occur, dirt buildup becomes a more important maintenance factor. That being said, it is claimed LED luminaires are less prone to dirt accumulation. [...]

Below is my contribution to the April issue of tED Magazine. Reprinted with permission. Outdoor lighting has proven a key market for LED sources due to their durability, directionality, efficiency, longevity, color and optical control. While metal halide and high-pressure sodium remain predominant in the installed outdoor lighting base, LED has captured a majority of [...]

LightingEurope and the International Association of Lighting Designers (IALD) have issued a joint statement on humancentric lighting. The statement seeks to define humancentric lighting and its benefits and elements. Humancentric lighting is viewed within the context of delivering certain benefits of light to specific applications and users. The elements are broken down into technical and [...]

At the 2016 IES Street & Area Lighting Conference, Greg Ortt, southeast sales manager for Hubbell Control Solutions, presented on the topic of the concept of Crime Prevention Through Environmental Design. This concept crosses disciplines in design, operations and maintenance to minimize elements in an outdoor space’s design that may inherently pose security risks. Lighting [...]

At LEDucation 2016, Acuity Brands’ Peter Ngai discusses the concept of surround lighting as a notable strategy. This strategy introduces another layer to ambient-task in workspaces. Its purpose is to light the volume of the space by emphasizing vertical illumination. Using a simulation, Ngai demonstrates that adding surround lighting can increase dimensionality (better modeling) and [...]

Seniors represent the fastest-growing segment of the population with over 40 million Americans over 65 (U.S. Census Bureau, The Older Population. 2010), with over 10,000 Baby Boomers turning 65 every day. The over-40 population represents approximately 89 million people and of those, 63% have vision problems (National Eye Institute of the National Institutes of Health [...]

My lighting column for the February issue of tED Magazine. Reprinted with permission. According to the U.S. Department of Energy (DOE), more than 600,000 retail buildings are currently operating in the United States, representing more than 11.3 billion sq.ft. As one of the largest markets for lighting, retail applications have distinctive needs. “Lighting in retail [...]

I recently had the pleasure of interviewing Sally Lee, LC, LEED Green Assoc., Market Segment Manager – Retail, LEDVANCE (formerly OSRAM SYLVANIA). The topic: trends in retail lighting. I’m happy to share her responses with you here. The interview informed an article I wrote for the February 2017 issue of tED Magazine. DiLouie: How would [...]

An article recently published in LUX reflects on the role of lighting design in Building Information Modelling (BIM), which is evolving past a 3D construction modeling system to include all services, including lighting. This opens the possibility for BIM to become a new collaborative tool for design teams. From LUX: Typically, the lighting design for [...]
