Philips has this week announced the launch of the first direct LED replacement range for compact fluorescent lamps (CFLni) based downlights with 60% energy savings. The new Philips CorePro LED PLC range is the first ever LED alternative to compact fluorescent lamps in down lighting applications that comes in a fully retrofit form factor. It offers both Electro Magnetic (EM) and High Frequency (HF) ballasts compatible versions.
Compact fluorescent lamps are one of the world’s most common lamps used in downlights in general lighting applications in offices, hallways, staircases, receptions and meeting rooms.
Royal Philips have just introduced a new instant fit LED replacement tube intended to greatly reduces the cost of replacing existing fluorescent tube lighting compared to other energy efficient LED technology alternatives.
The commercial sector has for a long time been better than the residential sector at both reducing cost, and energy use, by dropping incandescent for fluorescent lighting. However, lighting a commercial building like a factory or a large store still requires vast quantities of power, and changing from fluorescent lighting to a LED based solution has until now required a large investment that will take a long time to recoup.
For just this reason Philips has developed a new InstantFit LED lamp that fits in to existing lighting fixtures, and that requires no rewiring. LED tube lamps use up to 50 percent less energy compared with common linear fluorescent tube lighting and also require less maintenance due to their long lifetime.
New York City Department of Transportation (DOT) Commissioner Janette Sadik-Khan, recently announced the installation of light-emitting diode (LED) fixtures across New York City. Effected areas include Central Park, the East River Bridges, Eastern Parkway and the under-deck of Manhattan’s FDR Drive. The new LED based lighting installations is intended to provide substantial energy- and cost-savings, while also providing good, and in some cases improved illumination levels to these public spaces.
“Energy-efficient LEDs light up our parks, bridges and streets and also bring years of cost savings to our city”, said Commissioner Sadik-Khan. “From recycled asphalt to low-emission fuel on the Staten Island Ferry to energy-saving necklace lights on the Brooklyn Bridge, we are engineering a greener, greater city for generations to come.” The LED program is expected to save nearly $300,000 in annual energy and maintenance costs fiscal year 2013, and additional savings is expected to follow.
NGK Insulators, Ltd. has announced it has developed gallium nitride (GaN) wafers that can double the luminous efficiency of a LED light source compared to conventional materials.
With the assistance of a research institute outside the company, tests were performed to measure the luminous efficiency of an LED element using NGK’s new GaN wafer. With an injection current of 200mA, the GaN wafer during the tests showed an internal quantum efficiency of 90%. The GaN wafer achieved a luminous efficiency of 200lm/W, which is twice as efficient as those on the market today. This in affect means that with this new solution the power consumption can be reduced by up to 50%, while upholding the same brightness of a traditional LED.
