They say that it will set a completely new standard in ‘glare-free’ high beam lighting technology and it will be offered as an option for new 2023 Porsche models.
Compared to the technology that is being used on the current Porsche models, this new technology sets itself apart as the matrix function for the low and high beams will be done by two separate light sources in each assembly. The single high beam matrix unit will be replaced by the two separate HD matrix units positioned in the lower points of each headlight. Overall, there will be four light units between the two headlight assemblies.
Developed in partnership with Hella/Forvia, Infineon, and Nichia, the new HD LED technology has placed 16,384 LEDs or pixels in each of the four units. In total, there are 65,536 pixels used for the high beam matrix function. It perates at an intensity of up to 160lx and together with the additional high beam, it amounts to 300lx per headlight.
To compare, the current single-unit LED matrix system in Porsche have 84 pixels per headlight, with a total of 168 pixels for the two light sources.
Manager Light Modules and Regulation head of lighting modules at Porsche Benjamin Hummel shared, “At 300lx, it is possible to project the high beam up to 600m. But it is not only about a certain range. You need good light distribution within the whole field, too. We achieved this with four light sources. The brightness of the centre and side areas can be continuously adjusted for added roadside illumination. Greater illumination leads to better lighting performance.”
New micro-LED technology is the breakthrough that enabled Porsche to put together the high and low beam function of their new HD matrix LED headlight into two separate units. Each LED is said to only be as thick as a human hair so they were able to put 16,834 LEDs or pixels in each of the headlight.
There is also the new HD ECU technology which gives automatic 3D graphic calculation of the light provided by each LED. Along with the camera mounted in the windscreen, the new innovative headlight from Porsche gives matrix properties with fellow road users, oncoming cars, and other areas to be removed from the light projection.
Manager Light Electronics and Functions Dominik Walter shared that the calculation included even the navigation, traffic, chassis, and steering parameters. Some of the functions that the new HD matrix LED headlight offers include regular low and high beam, glare-free high beam (also called Performance setting), dynamic safety zone, adaptive highway high beam, and sign glare reduction.
Despite the additional features of the new headlights, Porsche claims that there’s no difference in weight compared to the unit that it will replace.
