Novel Line Light Frame Design for Uniform Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line lights, including those with multiple LED light bars, suffer from poor lighting effects due to dark spots and inconvenient installation, making it difficult to weld rims and maintain uniform illumination.
Innovation Solution
A novel line light design featuring a frame formed by connecting four rims with embedded LED light bars, where each rim has a downward opening and flat plates connected to vertical plates, allowing for levelled LED light bar surfaces and electrical connections, and a diffuser plate to prevent dark spots and facilitate smooth installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED light bars are installed after rim welding is completed, then the lighting effect is improved, but the installation becomes inconvenient and dark spots are generated
Solution Approach 1:
The patent applies preliminary action by pre-forming installation grooves and positioning structures on the rims before welding. The grooves are prepared in advance to receive the LED light bars, and positioning protrusions are pre-formed to guide correct placement. This allows the LED light bars to be installed easily after welding without creating dark spots, as the pre-prepared structures ensure proper positioning and coverage.
2Strength
If rims are welded to form a frame, then structural strength is improved, but welding becomes difficult and affects subsequent LED light bar installation
Solution Approach 1:
The patent applies segmentation by dividing the rim structure into modular sections with standardized grooves and positioning features. Each rim segment is designed with identical groove patterns and positioning protrusions, allowing for simplified welding processes. The segmented design enables workers to weld smaller, more manageable sections rather than large continuous rims, reducing welding difficulty while maintaining structural integrity.
3Illumination intensity
If multiple LED light bars are used, then illumination coverage is improved, but dark spots still appear at corners and installation becomes more complex
Solution Approach 1:
The patent applies merging by integrating the grooves and positioning structures directly into the rim components themselves, rather than adding separate installation fixtures. The grooves are formed as part of the rim structure, and positioning protrusions are incorporated into the rim design. This merging of functions reduces the number of separate parts and simplifies the overall installation process, allowing multiple LED light bars to be installed systematically without increasing complexity.

AI summary
The present invention discloses a novel line light, comprising a frame which is formed by connecting four rims end by end in sequence, wherein each rim is internally equipped with an LED light bar (1); each one of the LED light bars can be a single LED light bar or formed by connecting a plurality of LED light bars; the bottom of each one of the rims is embedded into a diffuser plate; each one of the rims has a downward opening; each one of the rims has a first flat plate (2); the two edges of each one of the flat plates are respectively vertically connected with a first vertical plate (3) and a second vertical plate (4); the first flat plates of every two adjacent rims are in welded connection; the inner wall of each one of the second vertical plates extends out to form an inclined second flat plate (5); each one of the second flat plates is fixedly connected to a third flat plate (6); an LED light bar is fixed on the lower surface of each one of the third flat plates by screws; the lower surface of each one of the third flat plates is a little greater than the surface of each corresponding one of the LED light bars; a distance is kept between the outer side face (7) of each one of the LED light bars and each corresponding one of the second flat plates; and every two adjacent rims are fixed by mutually welding the second flat plates thereof.
