which are designed for installation in vehicles to increase

In 2008, the gallium-nitride device (mainly high-brightness LED) market has rapidly grown to $4.6 billion with the availability of high-quality sapphire and silicon-carbide substrates. And increasing demand for blue-violet laser diodes, UV LEDs, and other devices will provide significant growth of advanced substrates such as gallium nitride and aluminum nitride, according to the report.The report says that these advanced substrates will be needed to provide the lattice matching and thermal characteristics necessary to produce high-performance devices at high yields.At the same time, demand for higher device manufacturing throughput and lower costs will push sapphire and silicon-carbide (SiC) diameters from two inches to three and four inches, and ultimately to six inches.

A number of companies are in a position to provide such substrates as the market expands. These include larger established companies such as Sumitomo Electric, Cree, and Samsung Corning, as well as smaller technology-focused startups such as Crystal IS, Kyma, and TopGaN. The effort to develop advanced substrates, as well as to improve conventional substrate properties, is worldwide in scope and includes 80 companies and 65 universities and research centers.Based on the forecast demand for high-brightness LEDs, blue-violet laser diodes, and high-power, high-frequency electronic devices, the worldwide merchant market (excluding captive producers such as Cree) for substrates for gallium nitride devices is forecast to grow from $280 million in 2008 to $470 million in 2013, says the report. Advanced substrates such as gallium nitride and aluminum nitride are predicted to comprise more than 40% of the market in 2013.

The IR products cover a wide range of applications in a variety of output power classes. With a range of up to 200 m – depending on the external optics used – the infrared OSTAR Lighting (SFH 4750) will be showcased at the fair. The beam angle and radiant intensity can be adjusted to the application with standard secondary optics. The hexagonal honeycomb shape enables multiple IR LEDs to be combined into a large space-saving matrix so that the output power can be increased many times and therefore the illumination range can also be enhanced. Its major applications include industrial lighting for camera-based surveillance systems such as CCTV and intelligent transport systems (ITS).The OSTAR Observation also offers impressive performance. It has a range of up to 300 m – again depending on the external optics used – and is therefore ideal for night vision systems which are designed for installation in vehicles to increase the visibility range and safety at night. These IR LEDs can also be used for prefield recognition, for example in precrash sensors or in pedestrian protection systems.
