Osram Opto Semiconductors GmbH of Regensburg, Germany says that previously static light, which could only be switched on and off, has now been given a dynamic dimension with the prototype of its Osire E4633i LED – offering countless design options for car manufacturers. The more autonomous a car becomes, the more the ways in which it is used will change, says the firm. As developments progress towards autonomous driving, more attention is being focused on the passenger cell, in which light will become an integral part, taking on functional and design-specific tasks.
“In the future, the interior of vehicles will be more than simply a cabin for the driver and passengers. It will be an extension of our living space in which we will be able to work and relax,” believes Stephan Pawlik, marketing manager Automotive Interior at Osram Opto: “Light sources in car interiors will provide ambient lighting and perform a number of additional functions. For example, they could use dynamic and color effects to draw the driver’s attention back to the traffic in good time.”
To make it easier to provide such new functions in vehicles, Osram has installed a serial control driver from Inova Semiconductors in the new E4633i product from the Osire family in addition to the three color chips (red, blue and green). It is now possible for a large number of separate LEDs to be controlled via a serial bus system either individually or in groups, providing simple implementation of uniform color rendering across the entire color space as well as dynamic light cases. Control of the desired color and brightness has been simplified because the E4633i is precalibrated and can automatically correct color shifts in the red range caused by fluctuations in temperature. The LED has a pre-mold SMT package with a footprint of just 4.6mm x 3.3mm x 0.7mm. The compact package and the link to the serial bus now allow implementations with more LEDs in a much smaller space.
Since September, Osram Opto has been a member of the ISELED Alliance (Integrated Serial/Smart Embedded Light Emitting Diode) and aims to drive forward development in this field. The prototype of the Osire E4633i is being presented for the first time in booth 155 (Hall B4) at the electronica 2018 trade fair in Munich, Germany (13-16 November).
