Vehicle Lamp Optical Member Spacing for Uniform Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps, particularly those used in vehicles, face challenges in achieving uniform brightness and displaying emblems effectively due to hot and dark spots caused by inadequate distance between light sources and optical members, leading to suboptimal visibility and advertisement/public information effects.
Innovation Solution
A lamp design incorporating a light source module with a flexible substrate and a structured optical member featuring specific patterns and distances to optimize light distribution, including a heat dissipation member and cover member, ensures uniform brightness and enhances emblem visibility by spacing the optical member at least 10 mm from the light source module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the optical member is placed close to the light source module, then the lamp structure is compact, but hot and dark spots occur causing non-uniform brightness
Solution Approach 1:
The patent introduces a new spatial dimension by positioning the optical member at a specific distance (at least 10mm) from the light source module along the optical axis, rather than simply expanding the lateral structure. This dimensional adjustment in the depth direction resolves the contradiction by eliminating hot and dark spots while maintaining overall compactness through optimized spatial arrangement.
2Length of stationary object
If the optical member is placed close to the light source module, then the overall size is reduced, but emblem visibility deteriorates due to hot and dark spots
Solution Approach 1:
The patent resolves this contradiction by adjusting the position of the optical member along the optical axis (depth dimension) rather than increasing lateral dimensions. By maintaining a distance of at least 10mm from the light source module, the design eliminates hot and dark spots that interfere with emblem visibility, while keeping the overall lamp size compact through optimized spatial configuration.
3Illumination intensity
If the optical member is spaced at least 10mm from the light source module, then uniform brightness and emblem visibility are achieved, but the lamp structure becomes larger
Solution Approach 1:
The patent applies parameter changes by precisely controlling the distance parameter between the optical member and light source module (at least 10mm). This parameter optimization achieves uniform brightness distribution and clear emblem visibility while minimizing the volume increase, as the distance requirement is met with minimal additional space through careful structural design.
4Illumination intensity
If the optical member is spaced at least 10mm from the light source module, then hot and dark spots are prevented, but the device complexity increases
Solution Approach 1:
The patent resolves this contradiction through parameter optimization rather than structural complexity increases. By simply adjusting the distance parameter to at least 10mm between the optical member and light source module, hot and dark spots are prevented effectively. The design maintains simplicity by avoiding additional components or complex mechanisms, relying solely on this critical dimension parameter.
