OSRAM GmbH: Unique light source employing visible laser diodes provides designers endless product integration opportunities

Osram Opto Semiconductors and Corning Incorporated announce a co-marketing agreement to promote Corning Fibrance Light-Diffusing Fiber, a first-of-its-kind technology that embeds lighting into products using Osram laser diodes.

Fibrance fiber uses Corning’s glass optical fiber designed for thin, colorful, aesthetic lighting and Osram’s blue and green laser diodes to create endless design possibilities. Fibrance fiber is optimized for a variety of applications such as automotive interior, architecture, consumer electronics, major appliances and many more.

The flexibility and tight-bend capability of the fiber allows it to curve, wrap, or contour around objects – while maintaining bright and uniform light. The fiber is so small and thin it is nearly invisible when the light source is off, thereby enhancing a product’s overall aesthetics and user experience. Fibrance fibers disperse light, rather than transferring it, allowing it to emit vibrant, clear colors up to 50 meters in product length.

“We expect the automotive and consumer markets to be early adopters of this technology,” said Osram marketing manager, Sevugan Nagappan. “While Fibrance fiber is ideal for vehicle interior applications, the design possibilities and product integration opportunities are truly endless.”

Osram Opto Semiconductors plays a leading role in the laser industry and has been a pioneer in the development of direct green laser diodes based on indium gallium nitride. Osram’s blue and green laser diodes stand out due to their high beam quality, well suited for optical imaging of light and excellent efficiency, which minimizes their temperature increase and improves their performance life. In order to emit light, Fibrance fiber must be coupled to such a laser light source.

“With this fiber, designers can enhance a product’s appeal and functionality by adding light how and where they want it,” said Curt Weinstein, vice president and general manager, Advanced Optics, Corning Specialty Materials. “Our long-term goal is to get Fibrance Light-Diffusing Fiber into the hands of designers and let the capabilities of the product create new lighting possibilities.”
