Among the industries seeking ways to make technology smaller, lighting is no exception. Now, a team of scientists at the University of Strasbourg in France has developed the first single-molecule light-emitting diode (LED).
In October, the National Electrical Manufacturer’s Association (NEMA) continued its lighting product monitoring, revealing some interesting results that confirm change is occurring at the lamp level in the lighting industry.
Lighting and control technology advances and creative daylighting implementation are propelling green lighting practices. ECs are being called on to employ their technical and creative skills to install and program new products and technologies.
In March 2012, the International Code Council (ICC) announced the availability of the International Green Construction Code (IgCC), a new model code for constructing and remodeling buildings to a higher sustainability standard.
In the 2011 and previous editions of the National Electrical Code (NEC), installing low-voltage lighting in close proximity to the edge of a swimming pool was a Code violation, yet almost every backyard swimming pool with a landscaped yard has low-voltage lighting too close to the pool’s edge.
As part of the Obama Administration’s efforts to reduce energy waste in our nation’s buildings and help save Americans money by saving energy, the Department of Energy (DOE) announced the winners of the fifth annual Next Generation Luminaires Design competition for indoor lighting at the LEDucation
In any lighting system, lamps and auxiliary electrical devices fail and must be replaced. Dirt and dust accumulates on fixture surfaces and should be cleaned. System problems must be corrected, and lighting controls should be adjusted as space conditions change.
The Energy-Efficient Commercial Buildings Tax Deduction (CBTD) was created by the Energy Policy Act of 2005 to encourage investment in energy-efficient interior lighting, HVAC/hot water systems and the building envelope.
According to Department of Energy statistics, about 22 percent of all electricity generated in the United States is used for lighting, and about 10 percent of that is used for outdoor lighting and signs.
Following a major technological shift from mercury vapor to metal halide in the past decade or so, high-intensity discharge (HID) product innovation is focused on this source type, specifically pulse-start systems.
Joel Spira, who founded Lutron Electronics Co. in 1961, invented the first solid-state dimmer in 1959. For decades after, dimmers were largely used to control the aesthetic environment. Only in recent years has dimming become an important part of the energy costs saving debate.
“The new and emerging energy market is creating quite a buzz among ECs at conferences like Lightfair International with LED lighting at the center of the conversation,” said Steven Witz, vice president, Continental Electrical Construction Co., Oak Brook, Ill.
The next step is to develop the basis of design or design intent, which can be expressed using two best practice tools. The first tool is the lighting control narrative, a document that describes how the intended control system will satisfy the owner project requirements.
With the growing popularity of light-emitting diodes (LEDs) in different applications, manufacturers are offering more choices, leaving end-users with a dizzying selection of the latest and greatest technology, and they often pass off the specifying to electrical contractors (ECs) who are becoming m
These days, it seems every aspect of our energy consumption is transforming, and in that regard, the lighting industry is no exception. Within the lighting industry, light-emitting diodes (LEDs) have assumed a prominent role in the quest for greater efficiency and reduced costs.
