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. 

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.

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.

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.

There's an App for That

Amalgam technology, fairly common among plug-in compact fluorescent lamps (CFLs), is now available in linear T5HO, T5VHO and T8VHO fluorescent lamps, making fluorescent lighting competitive in many high-intensity discharge (HID) applications.

Dim and Dimmer

Satisfying peak demand can be very expensive for utilities, which pass this cost onto their customers in the form of time-variable pricing or demand charges. Utilities, therefore, share a common interest with their customers to reduce peak demand.

Lighting Design Techniques

The presence of light is rarely noted unless there is a perceived lack of it (dim atmosphere or shadows) or a perceived excess (glare). Like air, light is invisible and yet is everywhere in the visual environment, as we cannot see without it.
