June 13, 2005... A New Addition to the Family in the Non-Visible Range
Regensburg, Germany--Ostar Observation is the most powerful infrared (IR) light-emitting diode (LED) from Osram Opto Semiconductors and takes the Ostar family into the non-visible range. The Ostar Observation includes ten thin-film chips that provide an Impressive output of 5 W at 1 A forward current. The minimum life of the LED is 10,000 hours.
Like other members of the Ostar family, the Ostar Observation measures just 3 x 1 cm, yet it emits infrared light with a wavelength of 850 nm rather than visible light. This small area accommodates two rows of five 1 mm? thin-film chips. As a surface emitter, the IR LED emits almost all of its internally generated light from the top. This enables the LED to achieve excellent optical output, which is ideal for external optics. With a forward current of 1 A, it produces an output of 5 W, and its specially adapted package ensures that the resultant generated heat is reliability removed. Its thermal resistance is 4 K per W.
At 850 nm, the wavelength of the emitted infrared light is well suited for sensors in both CMOS and CCD cameras. The high optical output ensures that the surrounding area is well covered. In a vehicle?s night vision system, for example, the Ostar Achieves a range of up to 150 m.
In the past, the IR LED does not need a filter. It is also much smaller and can be easily installed. The equipment in which it is installed can therefore be made more Compact and flexible.
Ostar was launched in November 2004 and is Osram Opto Semiconductors? brightest light source. The Ostar Observation is the third member of this brilliant family. Other family members include Ostar Lighting and Ostar Projection.
Its impressive output combined with its small size and reliable heat removal, make the Ostar Observation ideal for use in night vision and surveillance cameras.

Solar power system is a new kind of energy-saving and environmentally friendly system. It is a system which uses PV modules to convert sunlight into electricity. It's made up of PV module, controller, battery and inverter. It is mainly used in some remote and power-unstable areas.
Solar PV systems are very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc.
Solar power system is mainly used to drive all kinds of household electrical appliances and office equipment, to solve the power shortage situation without electricity or people living or working electricity problem
