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.

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.
