Lighting

 

 

Lighting and controls is a huge, constantly changing, dynamic market. The ELECTRICAL CONTRACTOR lighting editorial listed below keeps current on technological innovations from LEDs, controls, and design to innovations in efficiency by traditional lighting formats. 

In the Age of Wi-Fi, even lamps have become part of the growing internet of things (IoT). According to “Navigant Research Leaderboard Report: Residential Connected Lighting,” companies that make IoT-friendly lamps are getting smarter, too, and the market is growing.

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.

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.

Human perception of colors in their environment is dependent on light. As electric light sources have varying spectral emissions, the electrical industry relies on metrics to report, evaluate and predict how colors will appear under different light sources.

Meet The New Code

Last year, the International Code Council published the 2015 International Energy Conservation Code (IECC), a model energy code that states and other jurisdictions can use in whole or part as their energy code. Today, many states base their commercial building energy code on the IECC.

Cree LED lighting helps create an inviting environment in the parking structure of Presence Saint Francis hospital in Evanston, Ill. The hospital benefits from the energy efficiency of the multilevel sensor in the VG Series LED luminaires, which lowers output from 100 percent to 25 percent after seven minutes of no occupancy detection.
A Walk in the Park: LEDs in Parking Garages

With tens of thousands of parking garage structures containing hundreds of millions of spaces to accommodate the nation’s 135 million-plus registered passenger cars, the U.S. parking garage sector is a robust market that accounts for significant real estate in cities and towns nationwide.

Awaiting Take-Off: LED Lighting

A lighting revolution is just beginning, and light-emitting diodes (LEDs) are leading the way. By the Department of Energy’s (DOE) most recent count in May 2013, LEDs represented less than 4 percent of overall installed lighting in the United States.

In the Driver's Seat: LED Drivers

The LED driver acts as a power supply for LED modules, regulating output voltage or current for the light source. It transforms and conditions incoming power (typically AC, but it may be DC) and drives the current to the LEDs.

Safety Check: Lighting retrofits


According to the U.S. Department of Energy (DOE), in 2010, more than 75 percent of lighting systems installed in the commercial building sector were fluorescent, with the majority installed in recessed troffer luminaires.
