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. 

In commercial building applications, dimming either is used to support visual needs (usually in response to manual input) or to save energy (usually in response to automatic input).

When attending large conventions such as Lightfair International (LFI), attendees expect to see industry experts with decades of experience. It is less expected to meet a college junior, as 2017 LFI attendees did in Philadelphia in May.

In the Age of Wi-Fi, even lamps have become part of the growing internet of things (IoT). According to “Navigant Research Leaderboard Report: Residential Connected Lighting,” companies that make IoT-friendly lamps are getting smarter, too, and the market is growing.

The ASHRAE/IES 90.1 energy standard provides legal jurisdictions with a model commercial building energy code. The 2013 version is the national energy reference standard recognized by the U.S. Department of 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.

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.
