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. 

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.

According to the U.S. Department of Energy (DOE), more than 360 million troffers (named for a cross between trough and coffer) provide general lighting in commercial building interiors.

Lighting technology has become smarter and easier to integrate wirelessly with other systems. The vanguard of lighting technology, LEDs are brighter, cooler, cost efficient and sustainable with a lower carbon footprint.

Cracking Down on Codes

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.
