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.

LEDs: Promise and Progress

Lighting evolves based on need. Incandescent made way for brighter fluorescent. Fluorescent made room for solid-state lighting (SSL). The next big idea may be light-emitting diodes (LEDs). While they are an SSL source, LEDs are new to general lighting applications.
