OSRAM Opto Semiconductors Announces Optimized, High-Performance OSTAR LED for General Lighting Applications; New OSTAR LED Offers 30% More Output and ''Shapes Up'' With New Hexagonal Configuration.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- OSRAM Opto Semiconductors today announced the newest member of its revolutionary, versatile, OSTAR OSTAR Ontario Small Town and Rural Program OSTAR Observer Singlehanded Trans-Atlantic Race (sponsored by UK newspaper Observer) OSTAR Order and Shipping Time Analysis Report (TM) light-emitting diode (LED) family. OSRAM's OSTAR LED, originally announced in October 2004, is a compact, high-power LED that now offers 30% more luminous efficacy Luminous efficacy There are three ways this term can be used: (1) The luminous efficacy of a source of light is the quotient of the total luminous flux emitted divided by the total lamp power input. Light is visually evaluated radiant energy. than previous versions. At 420 lumens and an operating current of 700 milliamps (mA), the six-chip design with lens is brighter than a 20-watt (W), low-voltage halogen lamp halogen lamp or tungsten-halogen lamp Incandescent lamp with a quartz bulb and a gas filling that includes a halogen. It gives brilliant light from a compact unit. . Setting new brightness records, the latest OSTAR LED is ideal for a wide variety of general lighting applications, including individual workplace lighting, reading lights, residential and commercial lighting and even specialty flashlights. "The new OSTAR's high luminous intensity Luminous intensity The solid angular luminous flux density in a given direction from a light source. It may be considered as the luminous flux on a small surface normal to the given direction, divided by the solid angle (in steradians) which the surface has earned it a place in applications that up to now have been open only to conventional light sources," said Ellen Sizemore, North American North American named after North America.

"This is significant to our customers because it offers them an efficient, long-life and compact alternative to traditional, cumbersome solutions. This type of innovation has the potential to change consumer lighting as it now exists." OSRAM's OSTAR for lighting applications is equipped with four or six series-connected chips and now has a hexagonal hex·ag·o·nal adj. 1. Having six sides. 2. Containing a hexagon or shaped like one. 3. Mineralogy shape that enables more LEDs to be linked together into space-saving, high-intensity packages. This arrangement provides designers flexibility in their solutions, from a single component lamp to a multi-component spotlight. A specially developed hemispherical lens, part of the standard equipment, improves the efficiency with which the light is emitted without affecting the beam characteristics. The six-chip versions of these high-output LEDs produce 420 lumens with a lens and 300 lumens without a lens, in each case at an operating current of 700 mA and an output of 15W. The four-chip versions produce 280 lumens with a lens and 200 lumens without a lens, in each case at an operating current of 700 mA and an output of 10W. The new OSTAR's high luminous intensity makes the device an ideal choice as a rapid flashing light Flashing Light is a rhythmic light in which the total duration of the light in each period is clearly shorter than the total duration of the darkness and in which the flashes of light are all of equal duration. for effect lighting or stroboscopes, as this mode of operation does not shorten the product's life. OSRAM credits its OSTAR LED lighting breakthrough to its proprietary thin-film technology that ensures all the internally produced light is emitted at the top of the device. The white color is constant from every viewing angle and comes from a color conversion based on the chip-coating method. The yellow converter, which enables conversion to white light, is located directly on the blue chip. About OSTAR for General Lighting Each OSTAR LED contains four or six high-power, thin-film indium gallium nitrite nitrite Any salt or ester of nitrous acid (HNO2). The salts are inorganic compounds with ionic bonds, containing the nitrite ion (NO2−) and any cation. (InGaN) chips. Because OSRAM's thin-film chip emits light only from its top surface, the resultant high chip luminance The amount of brightness, measured in lumens, that is given off by a pixel or area on a screen. For example, dark red and bright red would have the same chrominance, but a different luminance. can increase the optical system efficiency and reduce the size of optics for lighting applications. The OSTAR LED can be mounted to lighting fixtures without any soldering, utilizing precision positioning of screw holes, and then mounted to a heat sink with a thermal paste for optimum heat dissipation. Pricing and Availability The OSTAR is currently available for sampling, and production delivery is scheduled to begin in the second calendar quarter of 2006. Basic versions of OSRAM's OSTAR lighting LED are available without lenses for customer-specific options.
