Problem
Current light-emitting devices for vehicles, such as headlamps, face challenges in optimizing light emission regions to reduce manufacturing costs and operating energy while maintaining efficiency in fulfilling various light emission roles.
Innovation Solution
The implementation of a light-emitting device with a partition wall that isolates multiple emission regions, each with distinct emission factors, allowing for optimized light emission characteristics and reduced energy consumption by using fewer driving elements and larger emission regions for lower control burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light-emitting elements are used to fulfill various light emission roles, then light emission versatility is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The emission array is divided into multiple emission regions (first region, second region, third region) with different emission factors. Each region can be independently controlled to fulfill different light emission roles (e.g., high beam, low beam, cornering light), replacing the need for multiple separate light-emitting elements while maintaining versatility.
Solution Approach 2:
Different emission regions are assigned different emission factors (first emission factor, second emission factor, third emission factor) to optimize local light emission characteristics. This allows each region to be tailored for specific functions, achieving diverse light emission roles through spatial differentiation rather than using multiple element types.
2Adaptability or versatility
If multiple light-emitting elements are used to fulfill various light emission roles, then light emission versatility is improved, but manufacturing cost increases
Solution Approach 1:
The emission array is segmented into multiple emission regions within a single light-emitting element structure. This reduces the total number of discrete components needed, simplifying assembly and reducing manufacturing costs while still achieving multiple light emission functions through controlled emission from different regions.
Solution Approach 2:
A single light-emitting element with multiple emission regions performs multiple light emission functions (high beam, low beam, cornering light, etc.). This multi-functional approach replaces what would traditionally require multiple separate elements, reducing part count and manufacturing complexity.
3Adaptability or versatility
If multiple light-emitting elements are used to fulfill various light emission roles, then light emission versatility is improved, but operating energy increases
Solution Approach 1:
The emission array is divided into multiple emission regions that can be selectively activated. Instead of operating multiple separate light-emitting elements, only the required emission regions are activated based on driving conditions, reducing overall energy consumption while maintaining the ability to fulfill various light emission roles.
Solution Approach 2:
Only the necessary emission regions are activated to fulfill the current light emission requirement, rather than operating all light-emitting elements. For example, only high emission factor regions are activated for high beam, reducing total energy usage while maintaining functional versatility.

AI summary
A light-emitting device includes an emission array including a plurality of light-emitting elements and a partition wall. The emission array includes a first region and a second region adjacent to each other. The partition wall is configured to isolate the first region and the second region from each other, such that the partition wall at least partially defines the first region in the emission array. The first region is associated with a first emission factor and the second region is associated with a second emission factor, the second emission factor different from the first emission factor.
