Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle window light emitting structures lack efficient light reflection and distribution mechanisms, resulting in suboptimal lighting performance and increased power consumption.
Innovation Solution
A light emitting assembly is integrated into a vehicle window, comprising a light emitting element package and a reflector with a specifically angled reflection surface. The reflector is positioned on an electrode and structured such that the angle between the reflection surface and the base board satisfies the equation α=90°−θ/2, where θ is the angle formed with the vehicle's longitudinal axis, optimizing light reflection and distribution.

Engineering Contradiction Analysis
1Use of energy by moving object
If a light emitting assembly is integrated into the vehicle window with a reflector, then lighting efficiency is improved and power consumption is reduced, but device complexity increases
Solution Approach 1:
The patent combines the light emitting element package, reflector, and electrode into a single integrated light emitting assembly that is directly mounted on the vehicle window. This merging of components eliminates the need for separate lighting systems within the vehicle body, reducing overall system complexity while improving lighting efficiency and reducing power consumption through optimized light direction control.
2Illumination intensity
If the reflector is positioned at a specific angle to optimize light reflection, then lighting efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a particular angular parameter for the reflector (α=90°−θ/2) to optimize light reflection efficiency. By defining this precise angular relationship between the reflector surface and the light emitting element orientation, the patent achieves improved lighting efficiency while providing a clear manufacturing guideline that balances precision requirements with practical manufacturability.
3Device complexity
If additional lighting systems are eliminated by using the window-integrated assembly, then device complexity is reduced, but lighting performance may worsen
Solution Approach 1:
The integrated light emitting assembly mounted on the vehicle window serves multiple functions: it provides lighting, controls light direction through the reflector, and eliminates the need for separate lighting systems. This multi-functional design reduces overall device complexity while maintaining adequate lighting performance for the vehicle's operational needs.
