Optical Void Pattern Substrate for Multi-Beam Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting arrangements, such as those used in vehicles, require multiple substrates or lenses, leading to higher costs and complex designs, and are unable to achieve diverse beam or light ray emission patterns efficiently.
Innovation Solution
A subsurface laser engraving method is used to create strategic voids or fractures in an optical substrate, allowing light rays to be refracted and altered to produce desired beam or light ray emission patterns using a single optical substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple substrates or lenses are used in lighting arrangements, then diverse beam emission patterns can be achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple optical functions into a single substrate by creating different void patterns within the same optical element. Multiple beam emission patterns are achieved by forming different arrangements of voids (first void pattern, second void pattern, etc.) within one substrate, eliminating the need for multiple separate lenses or substrates.
Solution Approach 2:
The single optical substrate is designed to perform multiple functions simultaneously - it can generate different beam emission patterns (low beam, high beam, fog light patterns, etc.) depending on which void pattern the light passes through. This multi-functional design replaces what previously required multiple specialized optical elements.
2Adaptability or versatility
If multiple substrates or lenses are used in lighting arrangements, then diverse beam emission patterns can be achieved, but manufacturing cost increases
Solution Approach 1:
By merging multiple optical elements into one substrate with multiple void patterns, the patent reduces the total number of parts that need to be manufactured, assembled, and inventoried. This consolidation directly reduces manufacturing complexity and cost while maintaining the ability to produce diverse beam patterns.
Solution Approach 2:
The patent creates different beam patterns by varying the parameters of the void patterns (size, shape, arrangement, depth) within the same substrate material. This allows diverse optical functions to be achieved through parameter variation rather than through multiple different physical components, simplifying manufacturing.
3Device complexity
If a single optical substrate is used, then device complexity and cost are reduced, but achieving diverse beam emission patterns becomes difficult
Solution Approach 1:
The patent applies local quality by creating different void patterns in different regions or layers of the same substrate. Each void pattern (first void pattern, second void pattern, etc.) has specific local characteristics that control light refraction in particular ways, enabling diverse beam patterns to be generated within a single substrate through spatially varying structures.
Solution Approach 2:
The patent utilizes the third dimension (depth) within the substrate by creating void patterns at different depths and orientations. This dimensional approach allows multiple beam emission patterns to be encoded within the volume of a single substrate, with light interacting with different void patterns depending on its path through the substrate.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method reduces complexity and cost by utilizing a single optical substrate to generate diverse and customizable light patterns, enhancing lighting arrangements without the need for multiple lenses.
Implementation Method 1
directing a laser beam of a laser to a first surface of an optical substrate; creating an optical void pattern via the laser such that at least one void is formed in the optical substrate
Implementation Method 2
directing light rays from a light source towards the optical substrate such that a light path of the light rays is altered via the at least one void thereby generating a light ray pattern emitted onto an object positioned away from the optical substrate
Data Source
AI summary
A lighting arrangement system including a light source and an optical void pattern formed into a substrate. The optical void pattern is formed using a laser and includes voids configured to alter light paths of light rays emitted from the light source directed towards the void pattern. The light paths are altered to form a light ray emission arrangement emitted from the substrate.
