In 2014, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics to a group of scientists for their 1990s invention of efficient blue light-emitting diodes (LEDs), which enabled LEDs to generate white light.
Light-emitting diodes (LEDs) are increasingly common in lamps and lighting fixtures in a range of settings. They are even beginning to dominate in some applications, including high-wattage area and streetlights.
With tens of thousands of parking garage structures containing hundreds of millions of spaces to accommodate the nation’s 135 million-plus registered passenger cars, the U.S. parking garage sector is a robust market that accounts for significant real estate in cities and towns nationwide.
A lighting revolution is just beginning, and light-emitting diodes (LEDs) are leading the way. By the Department of Energy’s (DOE) most recent count in May 2013, LEDs represented less than 4 percent of overall installed lighting in the United States.
The LED driver acts as a power supply for LED modules, regulating output voltage or current for the light source. It transforms and conditions incoming power (typically AC, but it may be DC) and drives the current to the LEDs.
Light-emitting diode (LED) technology seems to be all the rage in the lighting industry, and those in the know are more than aware of its many benefits. However, for the average consumer, the world of LEDs is still an unknown.
The light-emitting diode (LED) offers energy savings, lower maintenance requirements and other advantages compared to incandescent sources. However, many LED products perform poorly with existing dimmer controls.
In the healthcare-lighting arena, the improvements and increasing affordability of light-emitting diode (LED) products, along with advancements in lighting control technology, enable creative lighting designs that benefit patients and staff members.
Roughly 70 million U.S. street and roadway lighting fixtures—estimated to be a $200–300 million market—represent big business for electrical contractors, especially as this application increasingly converts to light-emitting diode (LED) technology.
By all accounts, light-emitting diodes (LEDs) have emerged as the new, efficient source of lighting, making most consumers forget the short-lived reign of compact fluorescents, which replaced incandescents only a few years ago.
A new report by Allied Market Research, “Global Light Emitting Diode (LED) Market,” estimates this market will reach $42.7 billion by 2020, registering a robust compound annual growth rate of 13.5 percent from 2014–2020. The Asia-Pacific region dominates the LED technology market because it houses a
In October, the Royal Swedish Academy of Sciences awarded the 2014 Nobel Prize in Physics to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, for the invention of efficient blue light-emitting diodes (LEDs), which enabled LEDs to generate white light and has led to their use in general service lamps
It’s an exciting time to be in the lighting industry. Today, lighting systems can alter spaces without physically changing them, revitalize urban areas, facilitate interaction and community, communicate information, make spaces more interactive, and affect well being.
The U.S. Department of Energy (DOE) recently issued three reports that provide a snapshot of several light-emitting diode (LED) lighting markets and estimate potential energy savings for full adoption.
Lighting upgrades have long been recognized as one of the easiest, most cost-effective ways to cut a building’s energy use. Efficiency requirements are making some of these projects a necessity, as, for example, replacement T12 fluorescent lamps disappear from the market.
Department of Energy statistics reveal that approximately 22 percent of all electricity generated in the United States is used for lighting, and about 10 percent of that is used to power outdoor lighting applications.
