Porsche’s next generation high-resolution HD LED Matrix headlights are twice as bright as previous Porsche systems

The matrix combines over 16,000 individually controllable micro-LEDs onto a thumbnail-sized surface. There are 2 per headlight, 4 per car. The area lit is four times larger than previous premium systems.

As well as the usual masking of head and tail lights ahead,  other functions include lane illumination, construction and narrow-lane light and adaptive motorway high-beam lights. The high beam lights up to 600 metres ahead, large areas to the right and left of the anti-dazzling gap become significantly brighter.

ABOVE: Porsche HD Matrix Headlight

The HD matrix only activate the pixels needed so use less energy than other high-resolution systems.

The Four-point headlight graphics displayed at night are in addition to the four-point daytime driving lights and static cornering lights. The four-point daytime running lights can also be seen at night with both low and high beams in the new system. The HD matrix headlights will appear in successive model lines with identical module technology but adapted designs. During the R & D process, Porsche submitted over 25 patents.

Previous Porsche Matrix headlights had 84 cells, whereas the HD matrix LED system uses 16,384 pixels per module. The design of the headlight is clearly structured. Four almost squarely arranged light modules, each complemented by a narrow daytime running light strip above the module, trace the brand’s characteristic four-point design – by day and by night. The two upper bi-functional modules are identical and provide the courtesy lighting and auxiliary high beam with three LEDs each.

The heart of the new HD matrix technology is the two lower light units. Each features an identical LED array with integrated LED driver (ASIC) that generates an unprecedented high-resolution luminous flux in an area of just 12.8 millimetres by 3.2 millimetres. The system controller – comparable to a powerful graphics card – not only activates but also controls the brightness of each of the 16,384 individual light-emitting diodes per LED array in 1,024 steps. Different lenses, each with specifically ground  optical glass, complete the two HD modules.
