Headlamps
 

Light Sources

Fifty percent of all drivers feel stressed in poor visibility conditions.[1] The strain eases if the road ahead is well lit; good lighting is the best night vision system. Ever since cars were invented, HELLA has been setting innovation milestones and pursuing a forward-looking approach to lighting products and systems. We focus on enhancing both driving comfort and safety, plus the attractive design of HELLA lighting products lets manufacturers achieve specific vehicle designs and positioning strategies.

Lighting Systems

One of the first light-based assistance systems was the dynamic bend lighting function, which was introduced in 2003. In this system, the light modules rotate according to the steering angle, nearly doubling the range of visibility in a curve.

One advanced development based on dynamic bend lighting is the Adaptive Frontlight System (AFS). This system uses both the steering angle and the vehicle speed as parameters for illuminating the road. Based on this internal information, a cylinder in the VarioX module is used to create various types of light distribution, including town light, country light, adverse weather and motorway light.

The development of the adaptive cut-off line (aCOL) goes one step further. This feature also utilizes data gathered from the vehicle’s surroundings to generate the light distribution. A camera detects oncoming traffic and cars ahead, and a stepper motor turns the cylinder of the VarioX module to the required position within milliseconds. This means that the light cone always ends directly in front of oncoming traffic, or just behind the car ahead of you.

The glare-free high beam function means that drivers can drive with the high beam on at all times. If the camera detects other traffic on the road, the distribution of light from the high beams is adjusted to mask the specific area.

Now used to illuminate broader areas than ever before, LEDs will also perform the opposite function in the future. Targeted spotlighting functions will allow specific illumination of certain types of objects, such as children playing at the edge of the road. This draws the driver’s attention to these potential risks ahead of time, enabling faster responses.

LED Matrix Beam

The heart of the Matrix LED headlights is the mechanic free glare-free high beam. This allows the driver to travel in his vehicle with a permanent high beam without risk of dazzling oncoming traffic or any preceding vehicles. By means of a camera, oncoming and preceding traffic are detected and then, by the shutting down or dimming of individual LEDs, these vehicles are blanked out of the field of high beam light distribution in real time. The implementation of Matrix technology allows, for the first time, several tunnels to open simultaneously. One example of this is the scenario where several oncoming vehicles are driving one behind the other. While these are “masked out”, the high beam continues to illuminate all the areas between the vehicles and to the right and left of them at full power. As soon as no vehicle is any longer in the driver’s field of vision, the system once again reverts to full high beam lighting. In addition to the specific masking out of other vehicles, the light cone of the Matrix high beam also adapts to the driving situation, for instance in the case of negotiating bends when the dynamic bending light function is required. In such a situation, the intensity of the light cone can be varied on the sides or it can be focused on the middle of the road. Consequently the driver’s visibility at night improves dramatically while, at the same time, the risk of dazzling oncoming traffic is eliminated.

 

Such a function is technically possible thanks to the splitting up of the high beam into five reflectors, each one having a chip containing 5 LEDs. For the first time ever, the lighting expert, HELLA, has now succeeded in operating every LED on the 5-segment chip separately, whereby a total of 25 LEDs per headlight can be operated on full power or lowered as and when required.
