These mirrors are individually controlled by a sophisticated computer module, allowing for precise manipulation of the light beam. This level of control enables a multitude of intelligent functions that far surpass the capabilities of conventional headlights.
The Foundation: High-Definition Light Emission
The “digital” aspect of Digital Light stems from its ability to project high-resolution patterns onto the road surface. This is achieved through the micro-mirror array, which can dynamically adjust the angle and intensity of each individual light point. Think of it like a tiny, ultra-precise digital projector built into your headlights. This allows for a level of control over light distribution that was previously unimaginable.
How it Works: The Micro-Mirror Chip
The heart of the Digital Light system is a micro-mirror chip, similar in principle to those found in high-end projectors. This chip contains an array of thousands of individually controllable mirrors. An integrated camera system constantly monitors the road, traffic conditions, and road markings. This data is processed by a powerful control unit, which then instructs each micro-mirror to tilt in a specific direction and with a specific intensity. This rapid and precise adjustment of the light beam allows for a truly dynamic and intelligent illumination experience.
The Projection Function: More Than Just Light
While the core Digital Light technology offers unparalleled beam control, it’s the addition of the projection function that truly sets it apart.
