Hella reports further success for chip-based headlamp system
Automotive lighting and electronics expert Hella has further developed its innovative chip-based headlamp matrix system "Solid State Lighting | High Definition" (SSL | HD). The company has already received orders for this from well-known OEMs for series production.

As Hella reports, the headlamp technology will soon be used in a fully electric sports utility vehicle (SUV) from an international car manufacturer and in a premium vehicle from a German car manufacturer. Series production of the vehicles is expected to start in mid-2024. The total order volume amounts to up to 200 million euros over the term of the contract. Development and production of the headlamps will take place in the global Hella network, including in Germany, the Czech Republic and China.

Hella has implemented the chip-based, high-resolution SUV headlamp for the first time with an asymmetrical arrangement in which the SSL | HD module is only integrated on one side of the headlamp. The module also enables simple changeover from left-hand to right-hand traffic and vice versa. The digital pixel switching also provides further individualisation options such as coming-home and leaving-home animations and other communication functionalities. For example, symbols for interaction with the driver can be projected onto the road. To ensure optimal illumination of the road, the SSL | HD functionalities are complemented by other components such as BiLED and matrix modules.

Hella's SSL | HD technology represents an evolutionary further development of LED matrix systems. Linked to this is the claim to achieve both a very high light output and a very high range of functions with minimised size of the light modules. The SSL Micro-LED Clusters are electronic components in which currently between 100 and 25,000 LED pixels are arranged in a very small space. These LED clusters are combined as a light source in the headlamp and offer new application possibilities due to the higher number of pixels. For example, they enable partial masking of oncoming vehicles and the illumination of traffic signs. From a perspective, projections of the safety distance can also be realised or pedestrians or cyclists can be highlighted by means of light.
