The lamp has an extremely low-profile design, and the LEDs operate for the whole lifetime of the vehicle. According to Hella, this new technology will be ready for series production in one to two years.
Combining light guides with light curtains
Hella has also combined two new technologies in a combination rear lamp prototype for an imaginary sports car. Three plastic three-dimensional prism rods which are arranged in parallel take over the functions of direction indicator (outside) and stop light (inside). Two high-performance LEDs are all that each light guide needs as a light source.
The tail light is realized as a light curtain in the background and ensures a large-area homogenous appearance for the combination rear lamp.
LED combination rear lamp with three-dimensional function carrier
In another RCL prototype, the exterior design is related to the unique sail-shaped Hotel Burj Al Arab in Dubai. The free-standing three-dimensional technological heart of the lamp is visible behind a 500-mm-high transparent, sail-shaped plastic cover lens.
These modules can replace current standard filament bulbs as light sources. In these prototypes, Hella uses specially shaped plastic light-guide bodies for the rear fog lamp and reversing light, which radiate the light from two LEDs each.
