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. 

Crops, of course, have always relied on three things from nature: soil, water, and sunlight. If executives at AeroFarms have their way, though, the future of crop growing will be mesh cloth, small amounts of water, and LED lights.

Replacing the driver


The majority of LED lighting products use an electronic driver that functions similarly to a fluorescent ballast. The driver converts incoming alternating current (AC) to direct current (DC) and drives this current to the LEDs.

For a long time, the lighting industry relied on conventional, legacy light sources and traditional designs. Recent advancements in LED technology, however, have changed the face of the industry in terms of the form and function of luminaires.

Flicker in light sources is an old problem made new again in the LED age. Its effects range from annoying to debilitating, and solving it can be challenging. Even defining flicker is difficult.

Know Your Options

Energy standards implemented by the Department of Energy (DOE) and the Energy Policy Act of 2005 largely eliminated the manufacture and importation of fluorescent T12 magnetic ballasts in 2010, and new DOE standards will eliminate many popular 4- and 8-foot T12 lamps in 2012.

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.
