Strong results for Veeco, more MOCVD sales for Aixtron

Veeco continues to see strong orders from China and other regions, while Aixtron has reported more reactor sales in Taiwan.

Veeco has reported revenue of $255 million for the quarter ended March 31, 2011, of which Led & Solar revenue was $215 million and Data Storage revenue was $40 million. Revenue was down 15% sequentially, but increased 89% from the same quarter last year. The company's gross margin was 51% and non-GAAP net income was $57 million.

Veeco's bookings for the quarter totaled $231 million, of which $198 million was in LED & Solar. John Peeler, Veeco's CEO, said: "We continued to experience strong demand for MOCVD systems and, while China remained the majority of our bookings, we also received orders from key customers in Taiwan, Korea and the US."
In February 2011, Veeco announced its newest-generation MOCVD system, the TurboDisc MaxBright. Peeler said that Veeco shipped three MaxBright four-chamber systems during the first quarter of 2011.

"Orders have been received from three of the top-tier Taiwanese LED makers, as well as from key customers in Korea and China," said Peeler. "Customers are clearly recognizing that we are helping to enable the industry's transition to Led lighting with a unique value position and the most productive MOCVD systems on the market."

Looking forward, Peeler said that Veeco expects MOCVD order patterns to "remain lumpy from quarter to quarter depending upon the timing of customer deposits. We see order strength continuing in China as it builds its LED infrastructure for solid-state Lighting, and quoting activity in Korea and Taiwan is also picking up with improved utilization rates being reported at key customers."
Further Aixtron systems

In related news, Aixtron SE announced that its latest Close Coupled Showerhead MOCVD platform system, the CRIUS II, has been successfully qualified for mass production by Chi Mei Group.

The 55x2-inch wafer configuration CCS CRIUS II was installed and commissioned by the local Aixtron service team at facilities near the Southern Taiwan Science Park.

Also, Aixtron has received repeat orders from Taiwan-based led chip maker Epistar for multiple AIX G5 HT reactors in a 14x4-inch configuration. The systems are delivered in the first and second quarter of 2011.

Aixtron described the repeat order as "a further endorsement of G5's very rapid time-to-production and excellent system-to-system reproducibility, both of which are key factors in a highly competitive market and a considerable driver of cost reduction."

Ming-Jiunn Jou, president of Epistar, said: "The new reactors will form the backbone of our planned capacity expansion for our high-brightness LED production program. In particular, we have been impressed by the run-to-run and system-to-system reproducibility the G5 has shown. This makes the G5 the leading MOCVD system in terms of throughput and yield, allowing us to quickly ramp up our capacities and expand our product portfolio even further in the direction of solid-state lighting products."

Rensselaer Polytechnic Institute Makes a Breakthrough on Green LED

Rensselaer Polytechnic Institute Makes a Breakthrough on Green LED

It's reported that Researchers from Rensselaer Polytechnic Institute have created a new method for manufacturing green-colored Leds with greatly enhanced light output.

Led by led by Christian Wetzel, professor of physics and the Wellfleet Constellation Professor of Future Chips at Rensselaer, the research team etched a nanoscale pattern at the interface between the LED's sapphire base and the layer of GaN that gives the LED its green color.

It has received a good result. The new technique results in green LEDs with significant enhancements in light extraction, internal efficiency, and light output.

According to Wetzel, currently, every computer monitor and television produces its picture by using red, blue, and green. And we already have powerful, inexpensive red and blue LEDs. A similar green LED should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction."

Rensselaer researchers boost green LED efficiency

Rensselaer researchers boost green LED efficiency

Research at Rensselaer Polytechnic Institute leverages a nanoscale pattern to boost the optical efficiency of green Leds in the lab.

Green LED efficiency has long lagged behind the capabilities of red and blue devices, but researchers at the Rensselaer Polytechnic Institute (RPI) have reported significant improvements in the lab. The team is forming nanoscale patterns on a sapphire substrate that boosts light extraction, internal efficiency, and light output.

More efficient green LEDs would benefit both solid-state Lighting (SSL) in general-illumination applications and TV and display technology. Equally efficient red, green, and blue (RGB) LEDs could yield white light for illumination and could improve the color gamut in display or TV applications.
Rensselaer researchers boost green LED efficiency

Some early led backlights for TVs utilized RGB LEDs, but the designs generally had to include two green LEDs for every red and blue one - adding significant expense and power consumption to the design. Likewise, RGB LEDs have been used in lighting but the need for extra green LEDs limits the applicability.

Green LED inefficiency stems from a semiconductor physics phenomenon called the charge separation effect. In green LEDs, electrons and electron holes are separated in the quantum-well region of the device. Light is generated when electrons combine with electron holes, but the separation results in fewer such combinations in green LEDs. Researchers have struggled for years with the problem.

Christian Wetzel, Professor of Physics and the Wellfleet Constellation Professor of Future Chips at RPI, is leading the green LED research team. The team etched a nanoscale pattern between the sapphire substrate and the gallium nitride (GaN) material in which the LED is grown.

The team reports a doubling in the internal quantum efficiency of the LED. Moreover, the design enhances light extraction by a factor of 58%. The result could be brighter green LEDs although its unclear how soon the research could be applied in LED production.

"Every computer monitor and television produces its picture by using red, blue, and green. We already have powerful, inexpensive red and blue LEDs. Once we develop a similar green LED, it should lead to a new generation of high-performance, energy-efficient display and illumination devices. This new research finding is an important step in the right direction," said Wetzel. "Green LEDs are proving much more challenging to create than academia and the industry ever imagined."

The research team published the results of its work in a paper entitled "Defect-reduced green GaInN/GaN light-emitting diode on nanopatterned sapphire" that was published in the Virtual Journal of Nanoscale Science & Technology.

Wetzel's team was supported by the US Department of Energy, National Energy Technology Laboratory (NETL) Solid-State Lighting Contract of Directed Research, and the National Science Foundation (NSF) Smart Lighting Engineering Research Center (ERC), which is led by Rensselaer.

Positive Aspects Of Applying LED Tubes Over Other Fluorescent Tubes

This content talks about the positive aspects of employing LED tubes which are energy efficient and environmental protecting.

In these days, in this community of increasing environmental interest, demand for energy-saving bulbs is growing continuously. A lot of people and properties are in the market for lighting options, which could be inexpensive, quite practical and will reduce power utilization. LED tube does seem to be a better solution for the public.

LED is the composition of light-emitting diodes. Actually, these diodes are miniature semiconductors chips, that change electricity into light. The old incandescent lamp provides light as secondary output from intensely heated filament, which necessitates a lot of energy. LEDs conversely convert most energy flowing through them to light that’s why it could be significantly more efficient than the traditional incandescent lights.

The newest technology advances in fluorescent lighting is considered to be compact fluorescent lamps (CFLs). LED Light is however more efficient since it has much longer lifespan (25 times) than that of incandescent bulbs and (8 times) than that of fluorescents.

LED light is presented in different colors which generate a variety of effects in an area. When LED light is going to be chosen, either for workplaces or for residential installation, the level of lighting in that place should be evaluated. This is as a result of a number of levels, which could generate a bright glow or soft feel repeatedly. The reason is that LED light source is originally directional light source. The light output by LEDs is very directional. In another word, its beam angle is usually fairly narrow. Such characteristics could be negative aspect in certain lighting systems, for example, the applications which call for smooth and even lighting distribution. Yet, this downside is not insuperable. Lighting developers usually implement a mist lamp cover rather than a clear cover for the LED tubes, therefore the light output could be very soft and evenly distributed. The price for this solution is some loss on light output – typically, roughly 10% of light output loss. Another use of a diffused lamp cover is to widen the beam angle of the tube, but still, LED tubes could not have a 360-degree beam angle just like the conventional fluorescent tubes do under present technology stage.

LED tubes are generally made of a silicon substrate that houses many LEDs. The substrate is enclosed in a PC pipe (cover) which makes it ready for installation. The LED tubes, unlike the fluorescent tubes, compact fluorescent lamps or energy-saving bulbs, do not contain any toxins or chemicals therefore could be released as common throw away.

One can find main health and environmental hazards, that can be linked with the incandescent and fluorescent lights because of the existence of mercury, that is highly risky and toxic. People who have worked under the enviroement (e . g ., warehouses and offices) where fluorescents are installed, may have a good comprehend of that the flickering lights can cause vision and eye problems, furthermore, some may even cause headaches and dizziness. While LED tubes do not engage such troubles.

Figure out the rewards of applying LED tube lighting for your office or home! You may find it an simple and easy way to enjoy a more comfortable life and at the same time to conserve your power bills.

The Benefit of LED Tubes Replacement

Back to 3 or 4 years ago, if someone talked about LED tubes, we may probably have no idea what it is about. But now, when we look around, we could probably see that LED light tubes have become a very hot topic and have been becoming more and more popular year by year or even day by day. The traditional fluorescent lights are widely and typically used in different lighting applications such as industrial lighting, warehouse lighting, commercial lighting, office lighting and residential lighting etc. But nowadays, it seems the moment to consider about replacing them with LED light tubes.


LED or referred to as Light Emitting Diode is environment friendly as they generate light by the movement of electrons in the diode. Comparing with LED, florescent lights waste most of energy to produce heat which are definitely no good to our environment. A typical LED light tube may include hundreds of LEDs. The actual number of LEDs depends on the size of the tube or the illumination requirements.


There area a great deal of positive aspects that drive people to try and make use of tube LEDs. For example:


- Can you imagine how much heat a fluorescent tube light can produce? Have you heard about the complaint made by those people who have to sit or work underneath or near fluorescent tube lights – haven’t mentioned that some of them claimed to suffer from frequent head aches. Not like the conventional fluorescent lights LEDs will not produce much of heat and they would not cause people any head aches. LED lights can be installed wherever you want them to be, living rooms, bedrooms, halls, buses, trains, boats, cabinets, etc. And of course, you may have probably notice there are some Christmas lights and curtain lights that are made of LED lights.


- LED tubes consume 60-70% less energy when in comparison with the fluorescent tubes. Typically, a 20W fluorescent tube can be replaced by a 8-10W LED tube; a 40W fluorescent tube can be replace by a 15-18W LED tube; a 60W fluorescent tube can be replaced by a 24-26W tube LED. And please keep in mind that if taking the ballast and starter into account, the tube LEDs can save even more energy as unlike fluorescent tubes, LED light tubes do not need any ballast and starter.


- LED tubes are available in different sizes and colors (in a more technical way of description, it means color temperature). Currently, LED tubes follow the traditional design of traditional fluorescent tubes (T5, T10, T10, T12 etc). The reason for that is to allow direct replacement of the existing fluorescents without extra retrofit cost by replacing the whole lighting fitting. As a result, the commonly obtainable sizes of LED tubes (take T8 and T10 for example) are 2 feet (600mm), 3 feet (600mm), 4 feet (1200mm) and 5 feet (1500mm) and 8 feet (2400mm). Another advantage it should be looked at is the diverse colors that LED lights can produce. Back in the fluorescent tube ages, the light color of a fluorescent tube can not be chosen. But now, with LED fluorescent tubes, the light color can be cold white, pure white, natural white, warm white, red, green, blue, yellow etc, extremely flexible and user-friendly.


- LEDs have much longer lifespan when compared with other lights. Theoretically LEDs’ lifespan can be as long as 50,000 to 100,000 hours. Of course, when it comes to a lighting fixture, the lifespan is not only about the LEDs, but also related to all other electronic components of the lighting fixture. However, this is the way how LED tubes can help to save your maintenance bills for failed lights replacement.


Despite the fact that there is variety of advantage of LED tube replacement, consumers tend to concern about the downsides. Below would be some of the most concerned drawbacks of LED light tubes:

- One of the major problems (and probably the biggest one) that bother the consumers is its price. LED tube lights are much more costly when in comparison with the fluorescent tubes and incandescent bulbs. The market prices normally vary from $50 to $100. However, considering the LED tubes can work for an prolonged time, the cost is acceptable, especially to those commercial applications that need long-time running.


- Retrofit work could be another issue which is concerned, as you may need to reset the electrical configuration in order to let the tubes work properly. The conventional fluorescent tubes require ballasts and starters which are not needed for the LED tubes. Therefore, ballasts and starters will be removed when installing LED tubes. This means a little extra rewiring work.


To summarize, the pros of utilizing LED tubes are considerably much more when compared with its cons. Its worth to have a try of tube LED replacement.
