Hella designs OTA-enabled taillights for Polestar 2
The automotive supplier Hella has implemented an integrated rear light bar made up of lighting and electronic components for the new Polestar 2. It gives the electric performance hatchback from Polestar its characteristic appearance. Software updates should also make new light animations possible in the future.

The C-shaped combination rearlight developed by Hella extends over the entire width of the vehicle with a light band of almost 300 LEDs, consisting of five electronically coordinated modules. All light functions and animations, such as coming-home and leaving-home scenarios, are controlled by software. This also opens up the possibility for the vehicle manufacturer to implement updated light animations on request by means of software updates without interfering with the hardware architecture.

"Combination rear lamps have long since ceased to be limited to safety-relevant functions," says Frank Huber, Hella's Managing Director responsible for the Lighting Division. "Rather, they also represent an important design element which car manufacturers can use to differentiate their vehicle models. This means that the demands on lighting technology and design language are increasing at the same time."

In order to implement the customer-specific requirements with regard to light animations flexibly and efficiently, the GAIN (Graphical Animation Interpreter) tool designed by Hella was used in the development process. The software basically enables car manufacturers to design light animations easily - starting with functions such as the "wiping" indicator, through individual choreographies for headlights, grille lighting, combination rearlights and the interior, to more complex animations for autonomous driving functions.

The combination rear lamps for the Polestar 2 are produced in the Chinese Hella lighting plant in Jiaxing. Hella had already produced headlamps and combination rear lamps for the first Polestar model, the plug-in hybrid Polestar 1.

Polestar is a joint venture between Volvo and its Chinese parent company Geely. The Polestar 2 has been delivered to customers since summer last year.
