Aixtron SE has a new order of one MOCVD system to power chip expert and existing customer AquaLite in China.
The contract is for one 55x2-inch CRIUS II reactor which will be dedicated to the growth of materials for high brightness LEDs and high Voltage (HV) LED production.
The system was ordered in the first quarter of 2011 and the local Aixtron support team will install and commission the new reactor in the second quarter of 2011 at the dedicated AquaLite power chip LED facility within its mainland China production plant.
James Dong, CEO of AquaLite, comments, “As the main supplier of power chip devices in China we have an unequalled understanding of the challenges of volume production of HB LED structures and HV LEDs. We therefore require the reactor with the best process economics, user control and uptime which are all strong features of the CRIUS II reactor.”
“Our thorough familiarity with the CRIUS systems and the easy process transfer to the CRIUS II mean there will be few if any problems ahead so the new system will quickly become a major asset. Aixtron has always supplied epitaxy equipment with excellent specifications and back that up with their highly rated support service. AquaLite is seeing a stronger demand for power chip LEDs so we look to the CRIUS II with its higher throughput to boost our capacity,” he continued.
“Last November, we acquired six CRIUS 31x2- inch configuration systems for high-power LED production, so I am confident that the new reactor will also be a very worthwhile new addition when it comes onstream.”
With state of the art epitaxial crystal growth and chip process technology, AquaLite’s LED chips have reached over the 100 lm/W efficiency, and thus are widely used in street lighting, lighting bars, light bulbs, and LED back lighting units.
Luminus launches RGB chipsets for ultra-mobile LED projectors
The new surface-mount products are individually assembled in a small footprint composed of red, green and blue LEDs.
LED innovator Luminus Devices is marketing the Compact SBT-16 and SBT-39 chipsets. These are the company’s newest Red-Green-Blue (RGB) LED chipsets targeted primarily to consumer projectors.
Both chipsets come in a surface mount package (SMT) and were designed to address the market demand for increasingly compact form factors while retaining very high brightness output.
Personal and ultra-mobile LED projectors are an emerging class of miniature projection devices with sizes typically ranging from 150 to 400 cm3. These projectors may include built-in digital media players and can connect to portable devices such as PDAs and notebook computers to provide a large display experience.
The new chipsets consist of red, green and blue LEDs that are individually assembled in a small footprint, performance surface mount package.
Each Compact SBT-16 device comes with a 1.6mm2 LED emitter and has a 18.5 mm2 footprint, a 70 % reduction over the previous generation device. They are engineered for the most compact palm-size or embedded projectors with performance ranging from 30 to 150 lumens depending on the available power budget.
The SBT-39 devices include a 3.9 mm2 LED emitter with a package footprint of only 33 mm2 and are designed for mid-range projectors whose performance ranges from 150 to 300 lumens.
“The Compact SBT-16 and SBT-39 chipsets integrate the latest advances in LED technology and allow our customers to create thinner, more compact projectors while retaining the high brightness that consumers expect from LED projectors,” said Stephane Bellosguardo, director of global product marketing, Display Business Group, Luminus. “Continued innovation in light source
