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.

LEDs: Their Future is (Really) Bright!

Debate continues about whether LEDs have the output in lumens, the color consistency and the price point to replace traditional incandescent, halogen and fluorescent lamps in high brightness and general illumination applications. Is it finally time to end the discussion?

The Value Proposition

It’s not often that an electrical contractor has the opportunity to sell a product line that saves a customer time, money and energy; promotes green sustainability; and reduces the load on the nation’s power grid. But that’s what industry observers say LED lighting sources can do.

Part of the Solution

Lighting fixtures are built around a given light source. In the case of LEDs, this task is more complex because LEDs are sensitive to heat and require special means to transfer it away.
