Innovative Lighting Systems – Rear Combination Lamp
These days, LEDs are key: Not only are they taking the automotive industry by storm due to
their energy-saving potential, they also offer a level of design versatility that is crucial to
developing a vehicle’s typical appearance. For combination rear lamps especially, manufacturersare exploring the many options available when LEDs are combined with optical systems,
creating attractive and distinctive vehicle designs.1.) Glowing Elements
A diffusely illuminated solid element creates a three-dimensional impression and can be used as
a versatile design feature. A volume spot designed as a glowing element ensures highly
Prism light guides are long rod-like light guides made of PMMA or PC with a typical diameter
of between 7 and 10 mm. The light guides generate homogeneous linear illumination. Each one
is equipped with LEDs at one or both ends. The light from the LEDs is coupled into the light
guide via a coupling-in lens, which sends the light onward via total reflection. Part of the light
meets the whole length of the back of the light guide, where the prisms are positioned; the prismsthen uncouple part of the light from the rod at 90° to its longitudinal axis. This method achieves
extremely consistent illumination along the entire rod.
Highly efficient direct reflector systems are the most common type of optical system. In a direct
reflector system, the light sources are positioned in a directly visible location in the vertex of the
reflector. The system can be placed at any angle (horizontal, vertical or inclined). The structure
of a direct reflector is determined by the distribution and positioning of the LEDs. A specific
section of the reflector is assigned to each LED. If the PCB is inclined, the positions of the LEDsare staggered, the distances between the LEDs vary or varying reflector geometries are used, the
individual sections of the reflector are staggered. The LEDs shine on the rear of the reflector,
An indirect reflector system is an efficient optical system with “invisible” light sources. It can be
placed at any angle (horizontal, vertical or inclined) and equipped with a conventional rigid PCB.
The structure of an indirect reflector is determined by the distribution and positioning of the
LEDs. A specific section of the reflector is assigned to each LED, and individual sections of the
reflector are staggered. The LEDs shine onto the reflector from the side, and the reflectordeflects their light toward the light exit at an angle of about 90°.
