As demand for LED lighting and controls increases, the lighting world is becoming more complex, which raises demand for expertise to produce good lighting solutions. Unlike other professions, lighting designers do not require state licensure.
In the name of efficiency, LED technology has rapidly displaced traditional lamps in many different lighting applications. One of the most cost-effective retrofits has taken place in the realm of street lighting.
In October, New York Gov. Andrew Cuomo announced plans to “transform” New York City’s bridges and tunnels “for the 21st Century.” The plan has four goals: reduce congestion, combat emerging security threats, increase flood resiliency and promote energy conservation.
The proliferation of alternative forms of lighting—for example, LED lamps—has been accelerated by the significantly limited sale of incandescent light lamps. In case you forgot, incandescents failed to meet the efficiency rules of the Energy Independence and Securities Act of 2007.
Major lighting trends—including LED, intelligent lighting controls, the industrial Internet of Things (IIoT), power over ethernet (PoE), energy codes, and light and health—are creating new opportunities and challenges for electrical contractors.
It’s hard to predict precisely what electrical contractors will face in 2017, because many things will influence the landscape where they work. However, there’s every reason to believe that new and emerging technology in a changing digital world should bring opportunity and optimism.
Crops, of course, have always relied on three things from nature: soil, water, and sunlight. If executives at AeroFarms have their way, though, the future of crop growing will be mesh cloth, small amounts of water, and LED lights.
Color tuning opens a world of opportunities in lighting design, proving itself useful in a seemingly endless supply of applications—designing lighting “scenes” for special occasions, creating different atmospheres for a hotel versus a hospital or shifting the color temperature of the light in the ro
For a long time, the lighting industry relied on conventional, legacy light sources and traditional designs. Recent advancements in LED technology, however, have changed the face of the industry in terms of the form and function of luminaires.
Recently, LED lights have been touted as the technology that would catapult the nation's lighting program into the future, but there is now growing concern over the potential negative impact of LED lights on human sleep patterns and nocturnal animal health and behavior.
The majority of LED lighting products use an electronic driver that functions similarly to a fluorescent ballast. The driver converts incoming alternating current (AC) to direct current (DC) and drives this current to the LEDs.
As local government and business owners look for ways to improve efficiency and reduce greenhouse-gas emissions, outdoor lighting has become one of the most practical ways for them to reach their goals.
LED streetlights have the potential to reduce energy consumption by about 50 percent compared to traditional high-pressure sodium lights. According to a U.S. Department of Energy (DOE) survey of governments and utilities, 62 percent of respondents reported using LED sources in their streetlighting.
Most parking garages are drab cubes of gray concrete; people don’t usually expect them to add much to a cityscape. However, the City of Fort Wayne, Ind., had different ideas when building the Skyline Garage.
