LEDs ♦ news digest
MOCVD makers all have technology roadmaps to enable COO reduction by three or four times within the next 5 years through a combination of improved yields, throughputs and precursor utilisation efficiency.
For MBE, Yole says Riber and Veeco are the only two players offering large capacity / large throughput MBE production tools for volume manufacturing. The market research firm expects both firms will maintain their dominant positions. However, there are about ten other MBE manufacturers offering R&D or pilot production systems that also have a strong presence on the general MBE market, such as DCA, SVT and Eiko.
The Metal Organic precursor market will also be driven by LED applications. But MOCVD reactor technology improvements, including yield, consumption and wafer size, will lower the amount of TMGa and TMIn needed per cm² of epiwafer.
The 2010 metal organic shortage ended in mid 2011 thanks to aggressive capacity expansion by leading suppliers. Further capacity expansion plans from established and emerging suppliers could come online within the next 3 years.
If executed as announced, Yole expects significant oversupply starting from 2012 that could continue through 2016 and beyond. This situation could put pressure on prices. Further MO synthesis technology improvements could provide opportunity for cost reductions. However, the usually volatile prices of raw indium and gallium also have a significant impact on cost.
Yole’s report provides Metal Organic precursor price, volume & revenue trends and data on over 150 companies.
small footprint and uniform emitting surface, the MT-G2 is an especially attractive device to further grow our leading position in professional-quality LED retrofit lamps.”
Featuring Cree EasyWhite Technology, the MT-G2 LED delivers up to 2100 lumens in warm white (3000K) at 25 W, 85°C and provides one of the industry’s best colour consistencies, with excellent optical control.
he new, brighter MT-G2 LED shares the same footprint as the original MT-G LED, providing customers a seamless upgrade path to shorten the LED luminaire and retrofit lamp design cycle and improve customer time-to-market. The MT-G2 LED is designed to be used as a single component in an LED design to better emulate the filament appearance of incumbent lighting products and simplify design and manufacturing.
“Innovation in performance and optimization of LEDs to a variety of applications are critical to driving LED adoption,” says Mike Watson, Cree senior marketing director, LED components. “The new MT-G2 LEDs enable true halogen performance across a wide range of single source lighting applications and provide the industry’s best colour consistency. Cree’s continued breakthrough in high lumen output demonstrates the advantages delivered by leveraging the SC³ Technology Platform.”
The MT-G2 LED is the latest product built on Cree’s SC³ Technology Platform, joining XB-D, XT-E, XT-E High-Voltage and XM-L High-Voltage LEDs. The SC³Technology Platform leverages Cree’s SiC technology, features advancements in LED chip architecture and phosphor, and showcases a new package design to deliver the most advanced LED components in the industry.
Cree pushes performance with 25 percent brighter LEDs
The new XLampMT-G2 LEDs showcase the advantage of Cree’s SC³ Technology Platform
Lighting innovator Cree, has unveiled the MT-G2 LED, its first EasyWhite LED array built on the SC³ Technology Platform.
The new XLamp MT-G2 LED delivers LED lighting manufacturers 25 percent brighter LEDs compared to the previous MT-G, enabling a wider spectrum of high lumen applications.
MT-G2 LEDs are designed for high-output, directional lighting applications and are the ideal replacement for lighting applications that currently use halogen lamps. The MT-G2 LEDs are optimised for use in track, accent, lamp retrofit, down lighting and other applications where colour quality, consistency and optical control are required.
“The MT-G2 LED truly pushes the envelope of what’s possible, redefining lumen levels and efficacy while delivering colour consistency and superior optical control,” notes Richard Turner, R & D director at Havells Sylvania. “Combined with the
Lumileds’ LUXEON M is a game changer
The new LUXEON M LED, designed for industrial outdoor applications, like streetlights, improves the design and reduces the cost of new products in much the same way the LUXEON Rebel did in 2007
Philips Lumileds has fully launched its LUXEON M LED, which is now in volume production.
The new emitter has already been approved for street lighting in major US cities with designs to be showcased at the Light + Building conference .

With an 8.9mm x 8.9mm footprint, the MT-G2 LED is available in 2- and 4-step EasyWhite colour temperatures ranging from 2700K to 5000K. The new LEDs are available in minimum 80 and 90 CRI options and feature multiple voltage selections, including higher voltages that enable the use of smaller, more efficient drivers to lower system cost.
XLamp MT-G2 samples are available now and production quantities are available with standard lead times.
