Welded LED Lamp Body for Omnidirectional Light Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing string lights face challenges in achieving effective light diffusion due to parallel light emission and require transparent materials, leading to poor diffusion and increased manufacturing time.
Innovation Solution
The illuminating lamp features a lamp body welded on both sides of parallel wires within an insulation layer, allowing 360° light emission and using a reflow welding process for efficient assembly, which can be done with non-transparent insulation materials, simplifying the structure and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED lamps are clamped at 90° orientation between two strings with light direction parallel to strings, then the structure is simple, but light diffusion effect is poor
Solution Approach 1:
The patent changes the mounting orientation of LED lamps from parallel to perpendicular relative to the string direction. By welding LED lamps perpendicular to the string axis, light is emitted radially in all directions around the string, transforming the light diffusion from a one-dimensional linear pattern to a three-dimensional omnidirectional pattern, thereby significantly improving light diffusion effect.
2Illumination intensity
If transparent string material is used for light diffusion, then light can be diffused, but manufacturing time increases due to one-by-one clamping
Solution Approach 1:
The patent replaces the mechanical clamping process with automated welding technology. LED lamps are welded directly to the string using welding machines, enabling batch processing and automated assembly. This substitution of mechanical assembly with automated welding dramatically reduces manufacturing time while maintaining structural integrity and light diffusion performance.
3Illumination intensity
If multiple LED lamps are combined to increase luminance, then brightness increases, but connection operation difficulty increases on small-volume thin metal wire
Solution Approach 1:
The patent replaces difficult mechanical connection operations on thin metal wires with automated welding processes. The welding technology enables reliable electrical and mechanical connections between multiple LED lamps and the thin string material, overcoming the limitations of manual connection methods and enabling efficient assembly of multiple lamps to achieve high luminance.
