Toyoda Gosei Develops Millimeter Wave Radar Compatible Car Logo and LED Shadow Lighting

Toyoda Gosei announced the development of the world’s first automotive logo with millimeter-wave radar penetration and light-emitting functions. The product will be used in Toyota’s new battery electric vehicle (BEV) Lexus RZ.

Previously, Toyoda Gosei had launched a millimeter-wave radar-compatible logo, which not only provided an attractive metallic appearance for advanced driver support systems but also penetrated millimeter-wave radar and light-emitting functions to highlight brand logos using LEDs and the like. Thanks to Toyoda Gosei’s metal coating technology and optical design technology, the newly developed logo has both transparency and luminosity. The product can also provide a light notification function (communication between the vehicle and the user) indicating the state of charge of the BEV or the approach of the driver, contributing to the realization of advanced functions and designs suitable for BEVs.

By continuously developing new products to integrate the sensing functions of millimeter-wave radar or LiDAR into front-end products, Toyoda Gosei will strive to contribute to the creation of safer and more attractive vehicles. On the same day, Toyoda Gosei also announced the development of a new LED light source unit that uses shadows to project patterns inside vehicles. The product will also be used in Toyota’s new battery electric vehicle (BEV) Lexus RZ.

By building a beautifully decorated pattern plate into the LED lights of the car’s interior lighting and projecting the light on the inside of the door, a new visual impression of the car’s interior space at night is created. Toyoda Gosei’s unique optical design technology emits LEDs diagonally from the front of the door to prevent shadows of passengers from being reflected, while also clearly projecting patterns in areas far from the light source.

Newly developed lighting products can provide different light colors and pattern changes. In addition, different interior materials can also show different appearances, which will contribute to the diversity of interior design according to vehicle grades in the future.
