LED Light Strip Plug Input Line Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light strips experience bright-dark areas when spliced together due to the power input line being on the same straight line as the light strip, requiring bending and affecting appearance and installation ease.
Innovation Solution
The input line is positioned on the side of the plug, with a light transmitting layer configuration that ensures seamless connection and continuous light emission by aligning the light exiting surfaces of the first and second light transmitting layers, and adjusting transmittance to minimize light differences at connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the power input line and LED light strip are positioned on the same straight line to facilitate electrical connection, then the electrical connection is simplified, but the light strip produces bright-dark areas when spliced and the input line must be bent for extension
Solution Approach 1:
The patent changes the spatial arrangement from a one-dimensional straight-line configuration to a two-dimensional L-shaped configuration. The input line is positioned perpendicular to the light strip body, forming a right angle connection at the plug. This dimensional change allows the input line to connect electrically without requiring bending during splicing, while maintaining uniform light emission across the entire light strip including connection areas.
2Ease of operation
If the input line is positioned on the same straight line as the light strip, then electrical connection is easier, but the input line requires bending when splicing multiple light strips which affects appearance and installation
Solution Approach 1:
The input line is repositioned from a collinear arrangement to a perpendicular arrangement relative to the light strip body, forming an L-shaped configuration. This spatial reconfiguration allows multiple light strips to be spliced together in a straight line without requiring the input line to bend, thereby simplifying installation while maintaining a neat appearance.
3Length of moving object
If multiple LED light strips are spliced together for extension, then the coverage length is increased, but the plug position creates bright-dark areas affecting appearance
Solution Approach 1:
The patent applies different light transmitting properties to different regions: the first light transmitting layer at the plug position has higher light transmittance than the second light transmitting layer on the light strip body. This local differentiation compensates for the light blocking effect at the plug position, ensuring uniform light emission across the entire light strip including spliced sections, thereby eliminating bright-dark areas while maintaining extended length.
Solution Approach 2:
The patent changes the light transmittance parameter of the light transmitting layer at the plug position. The first light transmitting layer is designed with a light transmittance of 30-80%, while the second light transmitting layer has a light transmittance of 10-50%. This parameter adjustment ensures that the plug position does not create dark areas, maintaining uniform light emission across the entire light strip.
