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.
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.
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.
The U.S. Environmental Protection Agency’s (EPA) Energy Star program recognizes and promotes products that satisfy a high performance standard while saving energy. Created in 1992, the voluntary labeling program now covers a broad range of products, including lamps and residential luminaires.
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.
The City of Birmingham, Ala., announced a new project designed to upgrade its current public parking garage lighting to energy-efficient, connected light-emitting diode (LED) lighting. The retrofits are expected to save about $375,000 per year.
As performance increases and costs decline, light-emitting diode (LED) lighting is poised to become the predominant light source in the United States. Meanwhile, adoption of integrated advanced lighting controls continues to grow.
When people think of the low-carbon economy and the multiple technologies in place that are fueling the growth of green, it is likely that most of them would point to wind and solar as the two most significant and influential drivers of the trend.
In March, I attended a Central Arizona Chapter International Association of Electrical Inspectors (IAEI) meeting. A discussion ensued about the growing number of improperly installed and uncertified light-emitting diode (LED) retrofit lighting kits.
The World Wide Web connects 10 billion devices and counting into a global network. Any network-enabled device can establish a link to the internet, raising the potential to join building systems appliances and more.
A marriage is happening. Light-emitting diode (LED) lighting and controls may soon be inseparable. While popular in offices, the combined benefits of efficiency, lower cost and building-operation analysis are extending to other workspaces.
Demand for wiring and cabling is expected to grow in the months and years ahead. Low-voltage applications for light-emitting diode (LED) technology and fiber optic cabling within the power-generation and telecommunications industries will help drive this market.
