Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive lighting manufacturing technology, specifically to a novel integrated light source suitable for headlights. Background Technology
[0002] Modern car headlights have evolved to a new stage, transforming from simple illumination functions into intelligent headlights that integrate intelligent driving assistance systems. For example, they use adaptive driving beam technology to automatically adjust the light beam area based on the position and distance of oncoming vehicles, avoiding glare for oncoming vehicles while meeting the driver's visibility needs.
[0003] With continuous technological advancements, the automotive headlight industry is undergoing a transformation from traditional light sources to LED light sources. LEDs, due to their advantages such as high brightness, low energy consumption, and long lifespan, are gradually becoming the market mainstream. Simultaneously, automotive headlights have evolved from a simple illumination function to a new stage of intelligence and technological sophistication. Intelligent technologies such as adaptive headlight systems and adaptive driving beams not only enhance nighttime driving safety but also increase their ability to interact with the surrounding environment. The development of high-resolution digital headlight technology, especially DLP and Micro LED technologies, enables headlights to achieve more precise lighting control and more complex projection functions. The application of these technologies not only improves the accuracy of lighting but also brings greater personalization and innovation to automotive design. With decreasing costs and optimized performance, the application scope of LED headlights is constantly expanding, indicating that future automotive headlights will be more intelligent, energy-efficient, and safer, meeting ever-increasing driving demands and market trends.
[0004] Currently, intelligent headlights mainly consist of a combination of adaptive low beam headlights, adaptive matrix headlights, and high-resolution intelligent projection headlights, such as... Figure 1 The diagram shows a schematic of a conventional automotive headlight structure. The headlight 1 includes an outer frame 11, within which a low beam module 12, an ADB module 13, and a high-resolution projection module 14 are arranged. These three modules are separately configured, resulting in a larger overall headlight size and occupying more space. A large portion of the headlight space is occupied by the projection headlight and its water-cooling system. The structure is more complex, requiring the coordinated operation of multiple modules, increasing the difficulty of design and manufacturing. Due to the size effect, the smaller the existing micro LED pixel size, the more severe the impact of sidewall defects, leading to a decrease in external quantum efficiency and luminous efficacy at low current densities.
