OSRAM Opto Semiconductors has created the Osram Ostar Stage LED for stage lighting. It has at least double the lumen output compared to other members of the product family. At the same time, the surface of the component has only increased by 30%.

The LED contains a number of high-current chips with a surface area of ​​two square millimeters, each corresponding to a different color, each chip can handle up to 4.5A current. This is expected to make the stage moving lights and exhibition lighting more compact and powerful.
The Osram Ostar Stage is equipped with high current chips based on thin film and UX:3 chip technology. The surface area of ​​each chip is 2mm2, which is twice that of the earlier version, but the package size is only slightly increased to 5.7mmx6.4mmx1.3mm. These include red film chips and green, blue and white UX:3 chips.
Each chip can withstand up to 4.5A, meaning more light can be emitted from a smaller surface area. At a sorting current of 1.4A, the typical luminous flux of the red chip is 140 lm, and the green chip reaches 280 lm. The "dark blue" chip has a light output of 1.8W. If operated at a maximum current of 4.5A, the brightness of each color will increase by a factor of 1.6.
Since the Osram Ostar Stage features a new ceramic converter, the white light chip will have a lifetime of 20,000 hours (L50/B50) and a brightness of over 1000 lm at full power output.
OSRAM Opto Semiconductors has launched a range of LED products for stage, exhibition and architectural lighting, and Osram Ostar Stage is a member of the high output family.
Mr. Wolfgang Schnabel, Head of Product Marketing at OSRAM Opto Semiconductors in Germany, said: "We are constantly developing chips and packages for the Ostar Stage product family, hoping to provide customers with high quality products at various output levels. The goal of this LED is to increase The standard for output class moving lights."
