Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting source modules face challenges in maintaining uniform color temperature across different areas, particularly at the outermost regions, due to the use of light emitting devices with varying color temperatures.
Innovation Solution
The solution involves a lighting source module design where columns of light emitting devices with the same color temperature are alternately arranged on multiple circuit boards, with specific columns at both ends having the same color temperature to mitigate color temperature differences, utilizing first and second light emitting devices with different phosphors to emit white light at distinct color temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light emitting devices with different color temperatures are used to create varied lighting effects, then lighting versatility is improved, but color uniformity across the module deteriorates
Solution Approach 1:
The patent applies local quality by assigning different color temperature characteristics to different regions of the lighting module. Specifically, first light emitting devices with first color temperature are placed in first regions, while second light emitting devices with second color temperature are placed in second regions. This allows each region to have optimized local lighting characteristics while maintaining overall module functionality.
Solution Approach 2:
The patent employs asymmetry in the arrangement of light emitting devices by creating non-uniform distribution of different color temperature devices across the module. The first and second light emitting devices are arranged in an asymmetric pattern where their positions, quantities, and spatial distributions are deliberately differentiated to achieve both color variation and uniformity balance.
2Adaptability or versatility
If light emitting devices are arranged in alternating columns with different color temperatures, then lighting control flexibility is improved, but color temperature difference at outermost areas increases
Solution Approach 1:
The patent addresses outermost area color uniformity by applying local quality adjustments specifically at the boundaries. The arrangement ensures that first and second light emitting devices are distributed such that even outermost regions maintain balanced color temperature characteristics, counteracting the natural tendency toward color temperature differences at edges.
Solution Approach 2:
The patent achieves equipotentiality in color temperature distribution by arranging light emitting devices so that all regions including outermost areas maintain equivalent color temperature characteristics. This is accomplished through careful positioning and quantity balancing of first and second light emitting devices across the entire module surface.
3Adaptability or versatility
If multiple circuit boards with different color temperature devices are used, then lighting source functionality is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the lighting module into multiple circuit boards, with each board carrying specific light emitting devices. This segmentation allows independent control and optimization of different color temperature regions while maintaining overall module integration and functionality.
Solution Approach 2:
The patent achieves multi-functionality by designing the module to simultaneously provide multiple color temperatures and lighting modes through the integrated arrangement of first and second light emitting devices. The same structural framework supports diverse lighting functions including varied color temperatures, brightness levels, and control modes.
