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 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.

Organic LED (OLED) is a solid-state lighting technology with strong potential for architectural lighting. The LED is a compact, directional point source. Shielding prevents glare, while heat sinking removes internal heat. In contrast, OLED is a flat (less than 1/8-inch thick), diffuse area source.

Human perception of colors in their environment is dependent on light. As electric light sources have varying spectral emissions, the electrical industry relies on metrics to report, evaluate and predict how colors will appear under different light sources.

Lighting controls save energy by turning off or reducing lighting when it's not needed. The smarter the control and the more flexible the light source, the greater precision in delivering maximum energy savings. Because LED lighting is instant-on and easily controllable, outdoor lighting control now offers higher energy cost savings through flexibility.
The Bright Outdoors: Outdoor Lighting Control

According to the U.S. Department of Energy (DOE), about 160 million lamps operated in the building exterior, parking area and roadway lighting markets in 2010. Building exterior made up 39 percent of these lamps, parking 33 percent and roadway 28 percent.

A suitable application for tunable white lighting is in classrooms. The system used in the room shown above offers four settings. In “calm” mode, the lights are set at a standard intensity level and warm shade of white light, oriented toward calming an excited class.
Tunable White Lighting

The color appearance of light sources can have a major impact on how people perceive spaces. In high-end retail, hospitality and similar applications, color temperature choice is a critical design decision.
