Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meteor lights predominantly feature single-sided illumination due to the use of PCBs, hindering the achievement of 360-degree illumination, and the occupied area by PCBs further complicates this goal even in double-sided LED attachments.
Innovation Solution
An LED meteor light design that eliminates PCBs, utilizing a transparent or semi-transparent tubular hood body with parallel bare conducting wires and LED luminous bodies arranged along these wires, enabling 360-degree illumination without the structural limitations of PCBs, and incorporating all necessary circuit elements within the LED luminous bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If PCBs are used to mount LED light sources, then the structure is simple and easy to manufacture, but 360-degree illumination cannot be achieved due to single-sided or double-sided LED attachment limitations
Solution Approach 1:
The patent extracts and removes the PCB from the system entirely. Instead of mounting LEDs on a PCB, the LEDs are directly attached to flexible supporting structures (wires or ribbons), eliminating the rigid PCB substrate that limits illumination to one or two sides. This extraction enables 360-degree illumination while maintaining manufacturing simplicity.
Solution Approach 2:
The patent transitions from the two-dimensional平面 mounting of LEDs on PCB surfaces to three-dimensional spatial arrangement of LEDs along flexible supporting structures. This dimensional change allows LEDs to be positioned in multiple orientations and directions, achieving 360-degree illumination coverage.
2Illumination intensity
If PCBs are used for mounting LEDs, then the structural design is straightforward, but the occupied area by PCBs hinders achieving 360-degree illumination
Solution Approach 1:
The patent removes the PCB substrate entirely from the system, replacing it with thin flexible supporting structures (wires or ribbons). This extraction eliminates the large occupied area of rigid PCBs while enabling 360-degree illumination through flexible LED arrangement in three-dimensional space.
3Ease of manufacture
If traditional PCB-based meteor lights are used, then manufacturing is simple, but soldering failures occur due to soldering shorts and false soldering
Solution Approach 1:
The patent replaces the traditional PCB soldering mechanical system with a flexible supporting structure system where LEDs are attached through alternative methods (such as adhesive mounting or wire bonding). This substitution eliminates the soldering process entirely, removing the source of soldering shorts and false soldering while maintaining ease of manufacture.
4Illumination intensity
If rigid PCBs are used to support LEDs, then the structure is stable, but the rigidity prevents flexible arrangement for 360-degree illumination
Solution Approach 1:
The patent replaces rigid PCB structures with dynamic flexible supporting structures (wires or ribbons) that can bend and adapt to various spatial configurations. This dynamic structure allows LEDs to be arranged in three-dimensional space for 360-degree illumination while maintaining structural stability through the flexibility and tensile strength of the supporting materials.

AI summary
An LED meteor light for 360-degree illumination and a method therefor. The LED meteor light includes a plurality of LED meteor light units. Each LED meteor light unit is free of a PCB but includes a hood body. A first bare conducting wire with rigidity and a second bare conducting wire with rigidity, parallel to each other, are at least arranged inside the hood body. A plurality of LED luminous bodies are arranged in sequence inside the hood body along a direction of the first bare conducting wire with rigidity and the second bare conducting wire with rigidity. Each LED luminous body is connected to the two bare conducting wires through a first connecting wire and a second connecting wire. The present disclosure facilitates 360-degree illumination without a PCB, and all necessary circuit elements are sealed inside the LED luminous bodies or beads, which prevents failures caused by the PCB, such as soldering shorts or false soldering, thus realizing a better structural design of the LED meteor light.
