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. 

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.


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.

In 2014, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics to a group of scientists for their 1990s invention of efficient blue light-emitting diodes (LEDs), which enabled LEDs to generate white light.
