Automotive Lighting have developed a technologically sophisticated new “2 + 2” LED rear lamp for the new BMW 7-series. The most important signal functions are realized in LED technology.
All LEDs are powered by a thin multi-wire flexboard already incorporating all the necessary electronics and ECU. The flexboard holds all the emitters for all functions of the lamp, Including for the logistically-challenging sidewall-mounted LEDs for the light guides. Each LED is laminated onto an aluminum carrier plate.
The flexboard is securely attached and riveted to the rear of the inner optical “hives”, so called for their resemblance to chambered beehives.

The inner optical hives are the functional element of this rear lamp combination which incorporates 53 precisely-computed round optic elements. |

The result is a homogenous appearance which acts as eye-candy from any angle of view. This is realised by releasing light into the sweeping light guides from the interior side of the lamp through 3 pairs of red TopLEDs arranged on a single PCB. From the outside, 2 groups of 2 additional red TopLEDs illuminate the two lower guides supporting the homogenous curved appearance |
The rear lamp’s signaling appearance automatically adjusts to diverse weather conditions, i.e. during bad weather and with the rear foglamp active, just one of the two brake light zones functions. Adding the rear foglamp gives the characteristic multi-zone effect visible in adverse weather conditions. This helps the following driver to detect any possible threat.
