Osram launches Ostune white LEDs for automotive ambient lighting
With car interiors becoming increasingly important in the latest generation of vehicles and undergoing a fundamental image change (leading to corresponding effects on design and integrated applications), Osram Opto Semiconductors GmbH of Regensburg, Germany says that its Ostune LED family now brings technical advances and insights from the general lighting industry to the car.
The first two products cover a wide color temperature range and enable OEMs to offer distinctive light variants for their ambient lighting: from bluish cool white to reddish warm white. The LEDs offer a coloring rending index (CRI) of more than 90, the highest CRI currently available for automotive applications, it is reckoned.
From high-performance LEDs for headlights to infrared versions for driver monitoring and RGB solutions for interior lighting, LEDs are increasingly penetrating the automotive market. However, in the field of ambient lighting, halogen lamps are still often used today - which not only require significantly more energy but also considerably more installation space.

The Ostune E1608 and E3030 extend Osram’s broad portfolio for automotive interior lighting by offering a wide color temperature range of 2700-6500K. In addition, they provide an energy-efficient and space-saving alternative to conventional technologies for many applications: from interior lighting and reading lights to mirror and footwell lighting. Due to the broad color range and ability to choose from many small bins, users can easily and precisely define their desired white tone and make it a fixed design element across vehicles, says Osram. In addition to the compact dimensions of 1.6mm x 0.8mm x 0.6mm (E1608) and 3.0mm x 3.0mm x 0.65mm (E3030), the products offer what is claimed to be outstanding color rendering in the car interior. The E1608 covers the lower brightness range up to over 7 lumens, and the E3030 the upper range up to over 70 lumens.
“Ambient lighting is becoming increasingly important with each new generation of vehicles,” says Hermann Senninger, marketing manager for Automotive Interior at Osram Opto. “With our Ostune product family, completely new designs are now possible, transforming the atmosphere in the interior from a functional workplace to a cozy living room simply by adjusting the color temperature.”
