Osram subsequently announced a new addition to its Golden Dragon family of high-power packages, aimed specifically at automotive applications such as daytime running lights. The devices produce a typical luminous flux of 64 lm from an operating current of 500 mA, compared with 40 lm for the previous version, and have a forward voltage which has been reduced from 3.8 V to 3.2 V. The company says that an optimized package, combined with a special carrier material, ensures excellent heat dissipation.
The new products are based around Osram's thin-film chip technology, which has been in production since 2002. The company continues to make iterative improvements to the technology, which is applicable to both InGaN-based devices (which are known as Power ThinGaN) and AlGaInP-based devices.
