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.

An interesting phrase comes up frequently in the rapidly evolving streetlight market: “real estate.” Most of us see a streetlight as a utilitarian lighting fixture, but manufacturers, utilities and city managers see a business opportunity enabled by a vast network of powered, connected devices.
