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.

As a digital replacement for their fluorescent counterparts, linear or tubular LEDs (TLEDs) are winning favor.

Recently, LED lights have been touted as the technology that would catapult the nation's lighting program into the future, but there is now growing concern over the potential negative impact of LED lights on human sleep patterns and nocturnal animal health and behavior.

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.

Lighting Design Techniques

The presence of light is rarely noted unless there is a perceived lack of it (dim atmosphere or shadows) or a perceived excess (glare). Like air, light is invisible and yet is everywhere in the visual environment, as we cannot see without it.
