Hella worked with Audi to develop the concept of headlight and new lighting in cars.

According to foreign media reports, the German automobile lighting factory HELLA and AUDI work together to develop a unique lighting technology for the new AUDI A7 Sportback, which can be applied to different headlights, such as LED, matrix LED lamp and laser beam high brightness matrix LED. The system uses a new control unit, which can be applied to all lighting functions, and the two sides jointly develop new lighting concepts in the vehicle.

HELLA's lighting technology has been used on the new flagship A8 of AUDI, and will also be used in the A7 vehicle system to provide the best road vision, and its anti glare light function enables other road users to avoid the glare of the beam. For example, the glare function can automatically cover other traffic participants to prevent glare. Reliable communication between front camera, sensor and headlamp is a prerequisite for the operation of high precision matrix LED with laser beam. The Hella control unit is responsible for controlling all functions of the headlamp: including low light, high beam, continuously lit steering lights and dynamic lighting effects for guests and drivers. Therefore, only one control unit can control all functions.

AUDI A7 uses 8 control channels to regulate the lighting effect of LED headlamps. This means that the 32 light-emitting diodes of the high precision matrix LED module can be controlled separately. In addition, it also highlights the unique daytime running lights. The A7 headlight contains 12 light distribution zones. When the driver opens the door, the headlamp will show dynamic lighting effect. At the end of the drive, the reverse lighting effect is displayed when the door is locked. In addition, the control unit is also responsible for controlling the continuous turning of the steering indicator.

The control unit conforms to the latest functional safety standards. For example, it can automatically adjust the headlamp to adjust the headlamp level to the best position to avoid other traffic participants from getting dizzy. In addition, it is equipped with a "fail safe" mode. The vehicle is equipped with a fail safe system, so the vehicle can still provide enough road lighting for the driver when the fault occurs.

HELLA not only developed the different dynamic effects and intelligent control functions of headlights with AUDI, but also created a new concept of interior lighting. With the help of optional atmosphere lighting components, dashboard, door trim panel and light guide strip on car door lights create a pleasant interior atmosphere for Audi A7 Sportback. The multicolored air lamp assembly further expands the lighting concept. The front row passenger's dashboard is decorated with chrome emblem with "Quattro" emblem. Lighting at night will show a particularly elegant effect. Audi has adopted special production technology and laser treatment technology to ensure the coating of chrome plated strips. Other light guides on the door and central console further create distinctive lighting effects. The protective panel of car door trim panel and central console is made of chrome plated stripe to create a high-end interior decoration effect. For this reason, the HELLA engineer used a special injection molding process.

The second generation RGB LED module, developed jointly with AUDI, allows motorists to adjust the lighting color according to their preferences, which constitutes the core of vehicle forming atmosphere lighting.

Through the setting of the top control unit in the front car area, Hella further realized its lighting and electronic professional technology docking. The control unit includes a SOS button and optional skylight control, cockpit monitoring sensors and microphones according to the vehicle configuration version. The integrated reading lamp adopts touch type design. The reading lamp installed at the center of the rear ceiling of the car supports independent brightness adjustment.

In addition to lighting and electronic products for A7, HELLA also provides other rich product lines that can bring huge added value to customers, highlighting its vision for actively shaping future travel solutions.
