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.

Over the last seven years, the LED Streetlight Replacement Program in Los Angeles has swapped more than 80 percent of the city’s 215,000 streetlight fixtures with LED units. To date, energy usage has lowered by 63 percent, saving the city approximately $9 million per year in energy costs.

Lighting Through the Ages

Starting around age 40, a person’s ability to see gradually diminishes. Statistics estimate one of the 78 million U.S. baby boomers turns 60 every seven seconds. These statistics verify the projection that half the U.S. population will be older than 65 by 2032.

Out of Sight, Out of Mind

When installing recessed fixtures, carefully consider the location of the units. The presence of combustible materials surrounding the luminaire is very important, and recessed lights can act as chimneys for heat loss and moisture transfer into attic spaces.

Companies Face the Lighting Race

According to Forbes, Boston-based Philips Color Kinetics and other firms are in a race to create technologies and appliances that do a better job of converting electricity to light, since the passage of the Energy Independence Act in December 2007 ensures the eventual obsolescence of traditional inc
