LED Lighting Module with Volumetric Contacts for Uniform Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The extension of LED lighting strips by concatenating modules results in an uneven illumination due to increased pitch interval between LEDs and exposes electrical contacts at separation points, making it difficult to maintain even illumination and handle the contacts effectively.
Innovation Solution
A strip-shaped carrier with material volume elements as electrical contact elements, allowing for robust and flexible contact options from multiple sides, which can be easily assembled and handled, and maintains uniform illumination by adjusting the pitch interval between light sources.

Engineering Contradiction Analysis
1Length of moving object
If LED lighting strips are extended by concatenating modules, then the lighting strip length is increased, but the pitch interval between LEDs increases resulting in uneven illumination
Solution Approach 1:
The lighting strip is divided into modular segments with standardized connection interfaces. Each module maintains its own LED pitch, and the modular design allows seamless concatenation without disrupting the overall illumination uniformity across extended lengths.
Solution Approach 2:
The patent modifies the connection interface design to maintain consistent LED pitch across module boundaries. By carefully designing the transition zones and adjusting parameters such as contact element positioning and module alignment, the illumination uniformity is preserved even when multiple modules are concatenated.
2Adaptability or versatility
If lighting modules are separated for extension, then the lighting strip can be reconfigured, but electrical contacts are exposed making handling troublesome
Solution Approach 1:
The electrical contact elements are extracted as separate, distinct components from the module body. These contact elements can be independently manipulated and connected, simplifying the handling process during module concatenation while maintaining electrical connectivity.
Solution Approach 2:
The contact elements serve as intermediary components between modules. They are designed to be easily engaged and disengaged, acting as mediators that simplify the connection process while ensuring reliable electrical contact between concatenated modules.
3Device complexity
If conventional contact elements are used, then the structure is simple, but the contact robustness is insufficient
Solution Approach 1:
The contact elements are constructed using composite material structures that combine different materials with complementary properties. This creates contact elements that are both mechanically robust and electrically conductive, achieving high reliability without excessive structural complexity.
Solution Approach 2:
The contact elements are designed with three-dimensional volume rather than being flat two-dimensional contacts. This volumetric design provides greater mechanical strength and multiple contact surfaces, enhancing robustness while maintaining reasonable structural simplicity.
