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. 

Traditionally, commercial electrical systems are based on alternating current (AC). The utility grid delivers AC power, which the building distributes. Low-voltage devices include a rectifier that converts AC to direct current (DC), with associated electrical losses.


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 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).

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.

Taking Stock

In June, The U.S. Department of Energy (DOE) released the full public use files from the 2012 Commercial Buildings Energy Consumption Survey (CBECS). This survey provides a massive amount of data describing the national stock of commercial buildings. How many healthcare buildings are in the South?

A Shakeup For T8

The U.S. Department of Energy (DOE) recently issued new energy standards for general-service fluorescent lamps, and the standards go into effect Jan. 26, 2018. The new rules are likely to primarily affect availability of standard 4-foot, 32-watt (W) T8 lamps and some reduced-wattage T8 lamps.

LEDs Under Control

It wasn’t long ago that light-emitting diodes (LEDs) were used primarily in very specific applications, such as indicator lights and exit signs. The deployment of white LEDs for general illumination applications always seemed in sight but out of reach.

Meet The New Code

Last year, the International Code Council published the 2015 International Energy Conservation Code (IECC), a model energy code that states and other jurisdictions can use in whole or part as their energy code. Today, many states base their commercial building energy code on the IECC.

State-of-the-Art Snapshot: LEDs

In 2014, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics to a group of scientists for their 1990s invention of efficient blue light-emitting diodes (LEDs), which enabled LEDs to generate white light.

Acuity Brand’s Trilia ceiling fixture, chosen by designer Leslie North for her home-based office, is marketed under the Winona Lighting nameplate.
The Other White LED

Light-emitting diodes (LEDs) are increasingly common in lamps and lighting fixtures in a range of settings. They are even beginning to dominate in some applications, including high-wattage area and streetlights.
