SCHOTT has launched Seran Luminuir™, which realizes true color without additional processes, creating a bright and clear LED light display using only a glass ceramic top without any filters or coatings.

SCHOTT announced on the 26th that it will launch the next generation CERAN Luminoir™ product to celebrate the 50th anniversary of the SCHOTT CERAN.

Since the launch of Schott Ceran in 1971, black glass ceramic has become the standard material for electric range tops in modern kitchens.

Now a next-generation product, Seran Luminuir™ boasts a new composition and manufacturing formula that provides greater transparency while maintaining a deeper black color.

It enables true-color LED lighting displays to be implemented without additional processes such as filters or coatings, reducing costs and production steps for home appliance companies. It also provides consumers with more intuitive operation of electric ranges and a dynamically designed top surface by implementing white and blue light more clearly, which is suitable for smart displays.

For electric ranges, which continue to enjoy popularity, not only cutting-edge technology but also design elements are very important.

To clearly see the controls, burner, and even the digital functions, the LED light under the top panel must penetrate the glass ceramic top as much as possible.

To this end, Schott developed the Seran Excite® solution in 2019, consisting of materials, filters, and coatings optimized for light transmission, and world-renowned brands such as Siemens and LG Electronics have already released products using Seran Excite®.

Taking this a step further, Seran Luminuwa™ makes the glass ceramic top even more transparent, allowing white and blue light to pass through brightly and clearly, while maintaining the deep black color of the top.

Its elegant black exterior offers appliance designers virtually limitless possibilities in product and lighting design, while reducing the complexity of product production, ultimately reducing costs for consumers.

“Unlike conventional glass-ceramics, which only show high transmittance in the high red range of the visible spectrum, CERAN LUMINIU™ shows uniformly high transmittance across the entire visible spectrum. This means that the material acts like an optical gray filter,” explains Dr. Jorn Besinger, Head of Product Management and New Business Development at SCHOTT CERAN®.

While white and blue light transmit particularly well, Luminua glass-ceramic countertops can express a wider range of colors even better. Even with diffused light or color gradients, colors appear more vivid and outlines are more distinct. While red light has been primarily used in cooking surfaces and digital displays, white light is expected to replace it. Furthermore, by eliminating the faint red tint of conventional glass-ceramic countertops, it appears as a luxurious, deep black, creating a sophisticated atmosphere in the kitchen.

“The new material composition enables a variety of lighting applications without additional filter layers, allowing customers to reduce production processes and costs. “As a result, we can implement innovative lighting solutions across a wider range of product groups,” explains Dr. Matthias Bockmeyer, Head of Development in the Cooking Business Unit at SCHOTT.

With these advantages of Seran Luminuir™, which is highly suitable for mass production, we expect to see improved lighting effects and digital functions soon in both premium and general product lines.

Ceran Luminuar™ was introduced at a customer event in early September and has already received positive market response. Discussions are also underway with domestic home appliance manufacturers. More information about SCHOTT Ceran Luminuar™ can be found on the SCHOTT World of Innovation website.
