Vehicle Lamp Modules Spatial Offset Homogeneous Light Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps with multiple light modules require a large number of components and complex adjustments to achieve a predefined light distribution, making them costly and inefficient.
Innovation Solution
The lamp design involves spatially offsetting numerous light modules with parallel primary directions, allowing them to be tilted so that rows of light pixels from different modules overlap, creating a homogeneous light distribution with fewer components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If numerous light modules are used to generate a predefined light distribution, then the light distribution quality is improved, but the number of components and device complexity increases
Solution Approach 1:
Multiple light modules are merged into a single integrated unit where their light distributions overlap. The patent combines several light modules with parallel primary directions into one lamp assembly, allowing them to work together to create a unified light distribution pattern rather than operating as separate independent units.
Solution Approach 2:
The light modules are arranged with spatial offsets in directions perpendicular to the main beam direction. By offsetting modules in lateral directions and tilting them appropriately, the patent utilizes additional spatial dimensions to achieve homogeneous light distribution without requiring each module to independently control every aspect of the light pattern.
2Manufacturing precision
If each light source has a dedicated collimator and screen opening, then the precision of light control is improved, but the number of components increases
Solution Approach 1:
The optical system is segmented into modular light modules, where each module contains a light source unit with integrated screen and collimator elements. This segmentation allows for standardized manufacturing of individual modules while maintaining precise light control through the dedicated screen-opening-collimator alignment within each module.
Solution Approach 2:
The light modules are designed as universal, interchangeable units that can be arranged in various configurations. Each module serves multiple functions: generating light, defining light pixels through screen openings, and collimating the light. This multi-functionality reduces the need for additional specialized components.
3Stability of the object's composition
If light modules are spatially offset and tilted to overlap light distributions, then the homogeneity of light distribution is improved, but the adjustment complexity increases
Solution Approach 1:
The light modules are designed with adjustable tilting capabilities, allowing dynamic optimization of the light distribution pattern. The modules can be tilted relative to each other to achieve the desired overlap and homogeneity, providing flexibility in adapting to different mounting conditions and achieving optimal performance.
Solution Approach 2:
The light modules are arranged with asymmetric spatial offsets and tilting angles rather than symmetric configurations. This asymmetric arrangement allows for optimized overlap patterns that achieve homogeneous light distribution while accommodating the natural divergence and beam patterns of individual light sources.

Function Achieved in This Case
This approach allows for the generation of a bright, homogeneous light distribution inexpensively and in a space-saving manner, with the ability to control individual light sources to avoid blinding oncoming traffic.
Implementation Method 1
a diffusion lens placed in front of the collimator in the main beam direction that spreads out the light pixels passing through the openings in the screen horizontally and vertically to obtain light spots forming a light distribution
Implementation Method 2
the diffusion lens has a first optical structure on the light-entry side, facing the collimator, which has a number of micro-optical elements, and/or a second optical structure on the light-emitting side, facing away from the collimator, which has a number of micro-optical elements, to deflect the light vertically and/or horizontally
Implementation Method 3
a collimator in front of the screen in the main beam direction that aligns the light emitted from the light source unit
