Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser headlamp systems lack the ability to implement high beam and adaptive driving beam functions due to limitations in light efficiency, design freedom, and weight, particularly with halogen, HID, and LED diodes, and existing laser optical systems fail to effectively manage beam zones.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If halogen, HID, or LED diodes are used as light sources, then the headlamp can provide illumination, but the light efficiency is low and power consumption is high
Solution Approach 1:
The patent transitions from conventional light sources (halogen, LED) to laser diodes, fundamentally changing the operating parameters and mechanism of light generation. Laser diodes operate on different physical principles with higher energy conversion efficiency, directly addressing the contradiction between light efficiency and power consumption
2Adaptability or versatility
If conventional laser optical system is used, then high light efficiency is achieved, but high beam function and adaptive driving beam function cannot be implemented
Solution Approach 1:
The patent divides the optical system into multiple independent beam splitters (first, second, third beam splitters) with distinct functions. Each beam splitter can be independently controlled to direct light to different zones (high beam zone, ADB zone, low beam zone), enabling multiple beam functions while maintaining modular system architecture that manages complexity
3Adaptability or versatility
If beam splitters are added to implement zone control, then adaptive driving beam function is achieved, but system complexity increases
Solution Approach 1:
The patent designs beam splitters that serve multiple functions: the first beam splitter creates high beam and ADB zones, the second beam splitter further divides light to create low beam zones, and the third beam splitter adjusts ADB zone intensity. Each component performs multiple operational roles, reducing the total number of separate devices needed while achieving comprehensive zone control

Function Achieved in This Case
Enables the adjustment of highlight and shadow zones and implements adaptive driving beam functions by optimizing beam output, enhancing energy efficiency and design flexibility while minimizing light source intensity loss.
Implementation Method 1
each of the beam splitters provided with a split coating surface inclined at an angle set with respect to the direction in which the beam is emitted to split the beam incident thereon into a transmitted beam and a reflected beam
Implementation Method 2
a fluorescent plate installed in a path of the beam reflected from each of the plurality of beam splitters to diffuse the beam incident thereon, wherein a fluorescent layer is formed on one surface of the fluorescent plate to change a color of the incident beam
