Lippstadt, 04. June 2013. At the 2013 Geneva International Motor Show, vehicle manufacturer PSA Peugeot Citroën presented Technospace, a concept that heralds the new Citroën C4 Picasso. For the tail lights of the compact five-door MPV, the French manufacturer has chosen to use innovative HELLA lighting technology. The design of the hybrid technology tail lights (LED/conventional bulb) clearly stands out on the market: this unprecedented light profile innovates with its double 3D-effect modules.
The tail lights' brake light/lamp functions, available as an optional feature, take the form of two 3D modules, each with 15 light-emitting diodes (LEDs). A thick-walled optic, teamed with one semi-transparent mirror that is set back slightly and another that is located at the front, create a 3D tunnel effect: when the light from the LEDs reaches the semi-transparent mirror at the front, it partially crosses it, whilst the residual light reaches the mirror that is set back a little and is immediately reflected. In this way, a 3D tunnel effect is created, despite the low geometrical depth of the tail lights. Other signaling functions are realized using conventional lighting technology. A basic version is also available with filament bulbs only.
