(December 27, 2022) The new high-resolution Porsche LED main headlights with HD matrix beam offer a high-resolution light distribution up to twice as bright than previous systems. Porsche has developed the light technology of the next generation with its new high-resolution HD matrix technology. The core element of the innovation created in collaboration with partners is a chip that combines over 16,000 individually controllable micro-LEDs onto the surface area the size of a thumbnail.

Of these LED chips, two are utilized for each headlight — four per vehicle. The headlights with HD matrix technology therefore offer a high-resolution light distribution up to twice as bright on a surface four times larger than previous top-notch systems.

The driver benefits from the highly flexible light that the new development makes possible thanks to extremely homogeneous illumination. In addition, there are innovative functions such as lane illumination, construction and narrow-lane light and adaptive motorway high-beam lights. The high-performance high beam turns night into day at a distance of up to 600 meters (372 feet). A new non-dazzling high beam function is used for oncoming vehicles: large areas to the right and left of the anti-dazzling gap become significantly brighter.

The new HD matrix technology adds yet another highly efficient component. Because the HD matrix headlights only activate the pixels that are actually needed at any given moment, they consume considerably less energy that other high-resolution systems, while the amount of light remains the same.

Four-point headlight graphics can also be displayed at night

In addition to four-point daytime driving lights and static cornering lights, the new Porsche headlight includes two of the new HD matrix modules and two bi-functional modules for courtesy lighting and the auxiliary high beam. These four main light sources are arranged in a four-point design characteristic of the brand. The previous top headlight from Porsche, by contrast, features four courtesy modules and a central Matrix module in 84-pixel technology.

World’s first high-resolution LED matrix light

The new technology must unite different, and sometimes contradictory, requirements in a single system. The aim is to distribute all light functions among four units per headlight for design reasons. Nonetheless, the individual sources of light should still combine in a way that provides homogeneous and powerful illumination at the same time. Pre-design simulations were used to analyze which overall system design would best meet all requirements — including those of customers. As a result, Porsche opted for the new and efficient HD matrix LED technology with 16,384 pixels per module rather than the maximum resolution that is technically feasible.

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 millimeters by 3.2 millimeters. 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.

The lenses produce different illumination angles. The wide-angle lens of the outer HD matrix module’s ‘illumination’ covers an angle of 40 degrees of width by ten degree of height. The inner ‘Performance’ HD matrix module with telephoto lens radiates the light at 20 degrees by five degrees. Its illumination is therefore only half as high and half as wide, but significantly brighter. The light distributed by the two HD modules overlap in the centre. The new headlight thereby combines wide illumination with high intensity in the central area.

Best possible visibility in any situation

The performance leap in light technology can be attributed to this efficient generation of light and the combination of the two HD matrix modules with the two bi-functional modules. With a total of 32,768 individually controllable pixels per headlight, the HD matrix modules generate direct high-resolution light. Only the light that is actually required is generated. This is why it is known as active matrix light generation.

The HD matrix light illuminates the entire 40-degree horizontal and ten-degree vertical range with a luminous flux of over 1,400 lumens, thereby generating one of the largest and brightest high-resolution illumination areas. It covers the entire high beam range and begins just in front of the vehicle. The light can be distributed in any way within this area and this flexibility makes it possible to improve existing functions and introduce new ones — always with the aim of offering the driver the best possible visibility in any situation.
