Vehicle Lighting Housing With Light Guide Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle lighting systems require separate lighting devices for different functions, each with its own control system and housing, leading to complexity and additional protection needs.
Innovation Solution
A lighting device with a housing that integrates a first illuminant for vehicle lighting functions and a second illuminant for component illumination, using a light-guiding element fastened to the housing, allowing both illuminants to be controlled independently and housed together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate lighting devices are used for different lighting functions, then each lighting function can be independently controlled and optimized, but the device complexity and number of components increases
Solution Approach 1:
The patent combines multiple lighting functions (headlight low beam, headlight high beam, and component illumination) into a single lighting device housing. The first illuminant provides headlight functions while the second illuminant provides component illumination, all controlled from one housing rather than separate devices.
Solution Approach 2:
The single housing structure serves multiple functions: it houses the first illuminant for vehicle lighting functions and the second illuminant for component illumination. The housing also provides mechanical support, environmental protection, and mounting interfaces for both illuminants, making it a multi-functional universal structure.
2Adaptability or versatility
If additional lighting devices are installed for component illumination, then component lighting functions are achieved, but the number of housings and control systems increases
Solution Approach 1:
The patent merges the component illumination function into the existing headlight housing structure. The second illuminant is installed within the same housing as the first illuminant, sharing the housing structure, mounting hardware, and environmental protection, thereby avoiding the need for a separate lighting device.
Solution Approach 2:
The single lighting device housing is designed to provide both vehicle lighting functions (low beam, high beam) and component illumination functions. This universal housing eliminates the need for separate control systems and housing structures for different lighting applications.
3Reliability
If separate housing structures are used for different illuminants, then each illuminant is protected from environmental influences, but the manufacturing and assembly complexity increases
Solution Approach 1:
The patent combines multiple illuminants (first illuminant and second illuminant) into a single housing structure. This unified housing provides environmental protection for all illuminants simultaneously, reducing the total number of housings needed and simplifying manufacturing and assembly processes.
Solution Approach 2:
The housing structure is designed as a universal protective enclosure that accommodates both the first illuminant for vehicle lighting and the second illuminant for component illumination. This multi-functional housing maintains environmental protection while reducing manufacturing complexity compared to multiple separate housings.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the lighting system by eliminating the need for separate housings and control systems for additional lighting functions, reducing complexity and environmental protection requirements.
Implementation Method 1
light generated by the second illuminant and emitted along the second light emission direction strikes a light coupling section (5b) of the light-guiding element (5), wherein incident light couples into the light-guiding element (5) via the light coupling section (5b)
