Cooking smarter: SCHOTT CERAN® makes lighting features on cooktops accessible for everyone
October 26, 2021, Mainz, Germany
- The new SCHOTT CERAN Luminoir™ glass-ceramic brings bright, clear and true-color lighting solutions to cooktops
- Developed in Germany, the glass-ceramic facilitates the production of cooktops with exceptional lighting design
Light connects people with technology. Light is an essential tool for transporting and exchanging information, be it in a data packet for global fiber optic networks, in an indicator behind the steering wheel of a car, or in a photo on a smartphone screen. The same is also true in the kitchen. Today's cooktops are both high-tech and a design element. Lighting solutions ensure that controls, cooking zones, or even digital features are visible when switched on. To make this happen, light – emitted by LEDs below the cooktop panel – has to penetrate the glass-ceramic as much as possible. With the CERAN EXCITE® lighting portfolio, SCHOTT has already developed a variety of coatings and filters that make the cooktops, from customers like Siemens (in the iQ700 activeLight model), more interactive and exciting. CERAN Luminoir™ takes this one step further: its newly developed composition makes the glass-ceramic more translucent allowing white and blue light, in particular to shine through brighter and clearer – all while maintaining its deep black appearance. That’s why CERAN Luminoir™ opens up new design possibilities for household appliance designers, at the same time reducing the production complexity of smart cooktops, ultimately saving consumers money.
New formula, new look
"Unlike previous glass-ceramics, which have a high light transmission especially in the high, red range of visible light, CERAN Luminoir™ has a uniform high transmission over the entire range of visible light. That means the material acts like an optical gray filter," explains Dr. Jörn Besinger, Head of Product Management & New Business Development at SCHOTT CERAN®. White and blue light in particular, but also color combinations, can penetrate better through the glass-ceramic. Colors appear more brilliant and contours even sharper – even with diffused light or color gradients. Whereas red has predominately been used in cooking zones and in the digital screen on cooktops to date, white light will play a greater role in the future. And, instead of a slightly reddish shimmer on the cooktop panel, the new glass-ceramic cooktop surface will look deep black at any time of day and make a real design statement in the kitchen.
A new cooking experience for everyone
"The new material formula enables our customers to save on production outlays and costs. This is possible because luminous and multicolored light features can now be produced without additional filter layers. This not only saves on material and production steps, but also makes innovative lighting solutions in cooktops interesting for broader assortment of customers," explains Dr. Matthias Bockmeyer, Head of Development in the Cooking division at SCHOTT. These advantages make CERAN Luminoir™ more attractive for mass production. Through this material, impressive lighting effects and digital features could be coming soon to standard cooking surfaces outside of the premium segment.
CERAN Luminoir™ was introduced at a customer event in early September and has already generated a positive market response. The new glass-ceramic can be viewed digitally at the SCHOTT World of Innovation.
