OSRAM's Eviyos LED Prototype Revolutionizes Smart Headlights
The hybrid LED provides smart headlights with more than 1,000 individually controllable pixels
The Eviyos prototype, developed by Osram Opto Semiconductors, is the world’s first hybrid LED. It represents major progress in the company’s quest to deliver the first market-ready, connected, high-resolution LED. When in use, the appropriate pixels are automatically switched off as soon as oncoming traffic is detected to prevent drivers of oncoming vehicles from being blinded. The prototype is part of a demonstration by Osram Specialty Lighting and will be on display for the first time at ISAL September 25-27, 2017, in Darmstadt, Germany.
Eviyos was developed in a µAFS research project, which was coordinated by Osram Opto Semiconductors and included partners in the industrial sector. The prototype combines two technologies in one component: a light-emitting chip and individual pixel control electronics. This combination allows the 1,024 pixels of Eviyos, as well as the driver, to be accommodated in a small footprint of approximately 4 mm x 4 mm. The light source has a minimum luminous flux per pixel of 3 lm at 11 mA. Initial prototypes have already exhibited more than 4.6 lm per pixel. Customers can vary the number of hybrid LEDs in their applications and supplement them with conventional LEDs, depending on the requirements.
“Eviyos is a prime example of our mission to improve the quality and performance of lighting applications with the integration of silicon semiconductor advanced technologies,” said Mike Godwin, Director of Automotive LED Marketing. “More than half of all accidents occur at night. Eviyos will help make our roads safer, while improving comfort and convenience for drivers.”
Eviyos is not only compact and powerful, but also energy-efficient thanks to the precise control and dimmable feature of the individual pixels. The only pixels on are the ones actually needed at the time.
Osram Opto Semiconductors plans to launch Eviyos at the start of 2020 as part of a separate product family, offering a wide range of possible applications. Smart headlights are just one of the potential areas in which intelligent selective pixel control can be used.
