equal to 88 system watts) and based on typical commercial usage of 12 hours per day and $0.11 per kWh electric costs.
“It takes more than incremental improvements in performance to achieve widespread adoption of LED lighting. Cree innovation starts with a clean slate, designing a new troffer with an attractive appearance that provides superior light quality, high efficiency and also enables fast installation,” says Norbert Hiller, Cree executive vice president, lighting.
“The ZR Series LED troffer is a winning alternative, offering uncompromised performance and an industry- leading 10-year limited warranty at a remarkably low price,” continues Hiller.
The ZR Series LED troffer’s thin 3.9” height and lightweight design enables faster installation without costly ceiling alterations. Offering a quick and easy one- for-one replacement of inefficient fluorescent troffers in education, healthcare and commercial building applications, the ZR Series LED troffer simplifies installation and significantly reduces labour costs during its 75,000-hour lifetime in all 1’x4’, 2’x4’ and 2’x2’ configurations.
The Cree ZR series LED troffer is sold through Cree lighting sales channels throughout the U.S. and Canada.
Yole: How LED lighting will shape the outlook for 2014
The highly fragmented LED industry will have to undergo some major transformations. With more than a hundred chip makers and thousands of packaging companies, much consolidation is needed
“Growth of the LED industry came initially from small LCD displays and keypad backlighting for cell phones. Then, the industry was driven forward by medium and large LCD display applications, with LED TV expected as the LED industry driver for 2011,” explains Pars Mukish, Senior Analyst, LED, Lighting Technologies and Compound Semiconductors activities at Yole Développement.
He adds, “However, the reality was quite different due to lower sales of LCD TVs, a lower than expected penetration rate of LED technology and a lower number of LEDs per TV set.”
The situation, mixed with the entry of several new players at the chip and device levels (mostly from Asia), created a climate of overcapacity, price pressure, and
strong competition.
As a consequence, packaged LED volumes were sharply lower than expected and revenue shrank due to strong ASP pressure. In 2012, most companies started moving to the new “El Dorado” of the LED business: General Lighting, which represented the next killer application.
In 2013, LED technology has really started to spread beyond general lighting, with the LED penetration rate greater than 5 percent in some applications (such as residential lighting, commercial lighting and road and street lighting).
However, to enable massive adoption of the technology, LED products still require a cost decrease in order to be able to compete with incumbent technologies (halogen...).
What’s more, the switch from a display driven market to a Solid-State Lighting (SSL) driven market poses many challenges for the many LED manufacturers that are not vertically integrated all the way through to lamps/ luminaires.
Indeed, to address the LCD display market, LED manufacturers just needed to discuss with Samsung and LG (or, to be more specific, their backlighting unit suppliers, of which there are only a handful) and develop a few types of LEDs.
With General Lighting, there are thousands of possible customers. The market is highly fragmented (in terms of applications and products). The channels to market have become much more complicated as they require a lot of commercial effort, and deal making with regional and local distributors.
Also, engineering gets requests to develop many different types of LEDs for each customer (one-chip package, multi-chip package, COB....). The segment becomes a “low volume/high product mix” type of market without the benefit of commanding the usual high prices.
