Adjustable LED Panel Lamp with Alternating Beads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Direct-type panel lamps with adjustable light emitting functions face space occupancy issues due to the increased number of light bars required for different color or brightness settings, leading to a larger internal space occupation.
Innovation Solution
The implementation of light bars with alternately arranged first and second LED beads, connected to separate circuits and driven by a module, allows for adjustable brightness and color temperature while maintaining a compact design by optimizing the arrangement and spacing of LED beads within the lamp's chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of light bars is increased to enable adjustable light emitting function, then the lighting adjustability is improved, but the internal space occupied by light bars increases
Solution Approach 1:
The patent combines multiple LED beads (first LED beads and second LED beads with different colors or brightness) into a single light bar structure. This merging approach allows the light bar to provide multiple lighting functions simultaneously, eliminating the need for separate light bars for each lighting mode, thus reducing the overall space occupied while maintaining lighting adjustability.
Solution Approach 2:
The light bar is designed with multi-functionality by incorporating both first LED beads and second LED beads that can emit different colors or brightness levels. This universal design enables a single light bar to perform multiple lighting functions (different colors, different brightness levels) that would traditionally require separate dedicated light bars, thereby reducing space consumption.
2Adaptability or versatility
If multiple separate light bars are used for different colors and brightness, then the lighting functionality is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple lighting functions into a single light bar by integrating both first LED beads and second LED beads within the same light bar structure. This reduces the total number of light bars from multiple separate units to a single unified component, thereby simplifying the device while maintaining diverse lighting functionality.
Solution Approach 2:
The light bar achieves universality by incorporating LED beads of different types (first and second LED beads) that can produce different colors and brightness levels. This multi-functional design allows one light bar to replace what would traditionally require several specialized light bars, reducing device complexity.
