One LED, two light colours

February 05

Lippstadt, Germany - A special technical and optical highlight on the new Volkswagen Golf Plus are the combination rear lamps using LED technology, which have been jointly developed by lighting specialists at Hella and Volkswagen. What's special about these lamps? LEDs that can emit both red and amber light are being used as light sources.

The combination rear lamps on the new VW Golf Plus have a two-part design. When switched off, four brilliant-white circles on a red base can be seen. The tail light, stop light and direction indicator are positioned at the respective outside edge of the vehicle. 36 LEDs per side serve as the light sources. For the tail light, all 72 LEDs emit red light. When the driver applies the brake, the two sets of 16 LEDs in the two inner circles light up with increased intensity and, together with the third stop lamp in the roof-edge spoiler (which also uses LED technology), form the now classic optical "warning triangle". When the driver switches on the direction indicator, the respective set of 20 LEDs in the outer lamp rings are activated and emit the prescribed amber light.

The LEDs have a two-colour design and the flashing amber colour outshines the red of the tail light

This even works with the tail light switched on, since the LEDs have a two-colour design and the flashing amber colour outshines the red of the tail light. LEDs have safety-related advantages, particularly with regard to the stop light and the direction indicator: LEDs react much more quickly than conventional filament bulbs. Traffic following the vehicle is therefore warned earlier. A further advantage is the homogeneity of the illuminated areas. Thanks to the use of diodes, the functional areas can be implemented completely with a brilliant look for the first time, without coloured intermediate lenses being necessary. The reversing light and rear fog light still use conventional filament bulbs as light sources, since this technology is most suitable for these functions.
