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. 

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.

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.

Juno Lighting Group’s Aculux LED precision recessed luminaire maintains color temperature through a range of dimming levels.

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.

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.

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.

A new national energy standard took effect on Dec. 30, 2010. On that day, all states had to certify to the U.S. Department of Energy (DOE) that they had a commercial building energy code in place at least as stringent as ASHRAE/IES 90.1 2004 or justify why they could not comply.
