Aixtron slashes revenue expectations by 25 percent
Despite generally positive results and continuing development activities in the optoelectronics industry, the LED market slowed down towards the end of 2011
Marketing firm Strategy Analytics says that the LED segment has adversely affected the semiconductor market.
The firm’s report, “Compound Semiconductor Industry Review July-September 2011: Optoelectronics,” captures product, technology, contract and financial announcements for companies such as Aixtron, IQE, Kopin, Soitec, Oclaro, GigOptix, Cree, JDSU, Avago Technologies, Finisar and Osram.
“When a leading equipment manufacturer in the very front end of the supply chain revises revenue and backlog expectations substantially downward, the entire segment takes notice,” observed Eric Higham, Director of the Strategy Analytics GaAs and Compound Semiconductor Technologies Service. “Mid- to long-term prospects for the LED market remain positive, but continuing economic turmoil and rapidly dropping prices have manufacturers in the LED supply chain on edge.”
Asif Anwar, Director, Strategy Analytics Strategic Technologies Practice added, “The optoelectronics market appears poised for growth. Optical device and network manufacturers are targeting 40 and 100 Gbps systems, a number of new LED products have been introduced and the US Department of Energy continues to make large investments in solar energy.”
Holophane introduces outdoor LED luminaires
The new LED fixtures offer efficiency in new or installed applications
Architectural appearance combined with sustainability and a high level of performance characterise new GranVille II LED luminaires from Holophane.
The fixtures offer the same timeless housing choices that made Holophane’s GranVille HID line popular and are offered with Classic or Premier prismatic borosilicate glass optics to facilitate use of new or installed pieces.
GranVille II LED luminaires
The GranVille II LED luminaires feature a new optical design that provides HID light levels while creating a comfortable wholly luminous appearance with low glare, less uplight and less light trespass. Multiple lumen packages are available and fixtures may be ordered with asymmetric or symmetric distributions. The luminaires are optimised to meet existing light standards.
“GranVille II LED luminaires represent the latest generation in the Granville family, which has become the benchmark for decorative acorn- style lanterns,” said Ben Prichard, Holophane Senior Product Manager, Outdoor. “The period style fixtures are highly efficient and provide significantly greater lumens per watt. Depending on the application, they also use less energy than traditional lamp technologies.”
Like most LED sources, GranVille II LED luminaires offer long life with reduced maintenance. A dedicated thermal management system maximizes
