Osram’s hybrid LED combines light-emitting chip and individual pixel control
The Eviyos prototype, developed by Osram Opto Semiconductors, is claimed to be the world’s first hybrid 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 company says.
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 1024 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 reportedly energy-efficient due 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 range of possible applications. Smart headlights are just one of the potential areas in which intelligent selective pixel control can be used.
