Shanghai, China, August 12, 2025 – ams Osram (SIX: AMS), a leading global supplier of intelligent sensing and emitter solutions, today announced that its next-generation OSTARTM Projection Power LEDs are setting the standard for LED technology innovation for compact projection systems and even future head-up displays (HUDs). ams Osram plans to test these products using the US automotive qualification standard AEC-Q102. Once completed, these LEDs will also be used in automotive projection systems. These LEDs not only offer a compact design but also precisely match the etendue of DMD (digital micromirror device) imagers, increasing projector brightness by 10-15%.

One LED, Two Applications: Projection and Automotive

Currently, projector manufacturers are challenged to develop brighter, smaller, and more efficient devices. The new OSTARTM Projection Power LED from ams OSRAM meets these demands with exceptional performance: it delivers up to 880 lumens of brightness in a compact 6.8mm x 7.6mm package, making it an ideal choice for mini and pico projectors. Optimized etendue matching for 0.3-inch, 0.4-inch, and 0.6-inch DMD systems maximizes light output. Automakers also benefit: the LED's exceptional brightness and color fidelity deliver crisp, high-contrast images for head-up displays, even in bright sunlight. Its compact design allows for seamless integration into space-constrained vehicle cabins.

Vicknes Ratha Krishnan, Product Manager at OSRAM ams, emphasized: "The new OSTARTM LEDs offer exceptional performance and a long lifetime, contributing to sustainable development, which is increasingly important for our customers. Maintenance and operating expenses over the product lifecycle are also significantly reduced."

Technical solutions for the highest demands

OSTARTM Projection Power LEDs stand out for their precise etendue matching, enabling optimal light coupling into DMD systems, ensuring maximum projection efficiency and brightness. Their compact design and high power density (up to 6.6A/mm² for blue and green versions) enable them to be used in even the most space-saving devices without compromising light output. With support for four-channel systems (amber, converted green, blue, and deep blue), these LEDs offer not only outstanding color rendering but also high design flexibility. Innovative chip technology with an isolation structure enables extremely high current density and ensures stable performance even under extreme conditions. Series chip connection and a low forward voltage design significantly simplify integration into existing systems. This reduces the complexity of the driver electronics and helps lower overall costs. Furthermore, the use of a copper metal circuit board effectively improves thermal management and is compatible with surface mount packaging, simplifying the assembly process. Compared to traditional light sources, these LEDs offer superior lifespan and reliability, making them particularly suitable for long-term operation in applications such as industrial projection and automotive applications.

With its new generation of OSTARTM Projection Power LEDs, ams OSRAM is setting the standard for LED technology innovation for compact projection systems and even future head-up displays (HUDs).
