Static ceramic converters enable superior luminance - A new product line from SCHOTT can accelerate the breakthrough of new compact laser light applications
The lighting solutions market seek laser technologies for their superior performance in a smaller package, and manufacturers demand sophisticated materials to optimize performance and reliability. For laser-pumped phosphor light sources, SCHOTT experts have developed special phosphor ceramic converter components, which power high irradiance and superior luminance. The international technology group SCHOTT will launch its new static ceramic converters product line at the CIOE 2019 in Shenzen, China (September 4 – 7, 2019). Integrated on a heat spreader, they enable innovative, compact light sources without moving parts.
“The brighter solution from SCHOTT offers the highest luminance as well as reliability and a high irradiance limit. The 100 percent inorganic ceramic converter material is soldered on the heat spreader to allow high power use. This requires a heat management to conduct the heat out of the ceramic sustainably,” explains Jens Vietor, Product Manager Ceramic Converters at SCHOTT. “With the now-unveiled static ceramic converter our customers can realize many different applications and designs enabling high brightness.”
SCHOTT´s ceramic converters have been widely adopted for use in powerful digital laser-phosphor projectors. They can also be used other applications, such as in searchlights, medical lighting like endoscopy, life science, or stage lighting.
“Our ceramic converters enable lighting innovations wherever superior luminance is key and create new opportunities for product designers in all areas of laser pumped phosphor-based lighting,” Vietor said. The standard heat spreader dimensions are 20 x 20 x 4 millimeters, customized formats are available on request.
SCHOTT´s ceramic-phosphor material offers outstanding performance with exceptional reliability, is extremely temperature stable, heat conductive and bright. It combines the properties of a ceramic with a highly efficient light conversion. The effect: The differently doped fluorescent ceramics convert blue laser light into high luminescent yellow, green and white light.
SCHOTT is a leading international technology group in the areas of specialty glass, glass-ceramics and related high-tech materials. With over 130 years of experience, the company is an innovative partner to many industries, including the home appliance, pharma, electronics, optics, life sciences, automotive and aviation industries. SCHOTT has a global presence with production sites and sales offices in 34 countries. In the 2017/2018 fiscal year, the group generated sales of EUR 2.08 billion with over 15,500 employees. SCHOTT AG has its headquarters in Mainz (Germany) and is solely owned by the Carl Zeiss Foundation. This is one of the oldest private and largest science-promoting foundations in Germany. As a foundation company, SCHOTT assumes special responsibility for its employees, society and the environment.

If the yellow or green light of the luminescent emission is needed, green or yellow converters fit best to an optical setup with a dichroic beam splitter. If white light is needed a "tilted lower beam" setup in combination with a white converter is recommended.
