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.

Knowing how light plays and today’s LED capabilities helped designers and contractors achieve a stand-alone space, the Blossom Cocktail lounge at the MGM National Harbor casino.

From high-definition panels to vibrant pinpoint light, from deep, true color to interactivity and animation, LED lighting is becoming the go-to option to create theatrics, mood and spectacle.

Sorry to BUG You

Lighting ordinances enacted across the United States in recent years have sought to reduce light pollution, such as skyglow, which is light emitted into the sky that obscures a view of the stars, and light trespass, which is light emitted onto neighboring properties.

Survey Reveals Awareness of Incandescent Lamp Phase-Out Growing

Public awareness of the federal phase-out of incandescent lamps is growing, according to the third annual Sylvania Socket Survey. Thirty-six percent of Americans reported that they are aware of the phase-out—up 10 percent from 2009.

Walls That Save Energy

Because surfaces and objects in typical spaces reflect light, they can play a part in lighting efficiency as extensions of the lighting system. By controlling room surface reflectances, light levels can be improved, creating opportunities to save energy.

Lighting on Display

Since the Frank Gehry-designed Guggenheim Museum Bilbao opened in the Spanish city in 1997, crowds of tourists have flocked there. Most say they come to see the museum, hailed as the most important structure of its time. And many stay to shop and eat, generating millions in revenue for the town.
