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.

Dimming Demand: Lighting Control in Demand Response

The average commercial building electric bill often features a consumption and demand component. The consumption component reflects the amount of electric energy (kilowatt-hours) used, and the demand component shows the maximum demand (kilowatts) during the billing period.

Hard Numbers: Responsive Lighting

Estimating lighting control energy savings is challenging, as actual savings depend on application characteristics, such as occupant behavior, building design, site orientation, daylight apertures, interior reflectances, device settings and level of commissioning.

The Right Light: Color Tuning

While light makes sight, lighting shapes perception, particularly in regard to color in the things we see. This is because visible white light is made of colors. For us to see an object as a certain color, that color must be present in both the light and the object.
