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. 

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.

According to the U.S. Department of Energy (DOE), more than 360 million troffers (named for a cross between trough and coffer) provide general lighting in commercial building interiors.

Knowing how light plays and today’s LED capabilities helped designers and contractors achieve a stand-alone space, the Blossom Cocktail lounge at the MGM National Harbor casino.

From high-definition panels to vibrant pinpoint light, from deep, true color to interactivity and animation, LED lighting is becoming the go-to option to create theatrics, mood and spectacle.

Transforming the Lighting Landscape

Some industry observers have predicted that solid-state lighting technology (SSL) will satisfy most lighting applications by the end of the decade. One particular SSL technology on the cusp of commercialization has the potential to be transformational: the organic light-emitting diode (OLED).

Let There Be Lighting...

Decisions on the appropriate lighting source are more pervasive than most of us realize. One could trace lighting design even as far back as the Bible, where in Genesis, Chapter I, God declares, “Let there be light.”

Study Suggests LEDs May Not Be So Eco-Friendly

Christmas light enthusiasts have always known not to drop what they are hanging. A broken bulb can spoil everything. Now they have another reason to be careful. Despite its growing popularity as a green lighting alternative, light-emitting diodes (LEDs) may not be as eco-friendly as advertised.
