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. 

The IIoT
 extends the utility of advanced lighting and control systems with additional sensing that can produce data and transform business.

The World Wide Web connects 10 billion devices and counting into a global network. Any network-enabled device can establish a link to the internet, raising the potential to join building systems appliances and more.


A combination of skylights, daylighting controls and LED high-bay fixtures reduces energy costs and increases productivity as better light levels make stock labels and codes easier to read.

A marriage is happening. Light-emitting diode (LED) lighting and controls may soon be inseparable. While popular in offices, the combined benefits of efficiency, lower cost and building-operation analysis are extending to other workspaces.

Color-tunable light-emitting diode (LED) lighting has unlocked enormous potential in lighting design, creating new applications.

Occupancy sensors automatically save energy by reducing lighting after a space is vacated. After more than 10 years of tightening commercial building energy codes, they are a staple in new construction projects.

LED: The Hype and the Reality

Noted for their efficiency and flexibility, light-emitting diodes (LEDs) are often billed as the second coming in the evolution of lighting. An exciting work-in-progress may be a better descriptor.

Walk Toward the Light

The green design—good for the environment in that it makes buildings more sustainable—can be bad for lighting, as designers are incentivized to chase points that may require sacrifices to design. For lighting, it can be especially risky.

In part 1 of this two-part series on photosensors, I described the major characteristics of photosensors and ended with a problem: suppose we have a classroom in which we want to begin dimming the row of fluorescent lighting fixtures adjacent to a series of windows when daylight levels reach 150 pe

Daylight harvesting’s value proposition is fairly simple: as daylight levels increase in a space, electric lighting levels can be automatically reduced to maintain a target task lighting level and save energy.

Once a venerable workhorse in commercial lighting, the fluorescent magnetic T12 ballast is now considered a dinosaur. All but extinct in new construction, there are still millions of these ballasts installed in commercial buildings throughout the United States.
