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 even double-sided LED attachments on PCBs are obstructive.
Innovation Solution
An LED meteor light design that eliminates PCBs, utilizing transparent or semi-transparent tubular hood bodies with parallel bare conducting wires and LED luminous bodies arranged along these wires, allowing 360-degree illumination without circuit failures from soldering shorts or false soldering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If PCBs are used to mount LED light sources, then the structure is stable and easy to manufacture, but 360-degree illumination cannot be achieved due to single-sided or limited double-sided attachment
Solution Approach 1:
The patent divides the traditional PCB-mounted LED structure into segmented LED luminous bodies, each containing its own circuit elements. This segmentation allows LEDs to be distributed in three-dimensional space around the transparent bead, enabling 360-degree illumination without requiring a planar PCB substrate.
Solution Approach 2:
The patent transitions from two-dimensional PCB mounting to three-dimensional spatial arrangement of LED luminous bodies around a transparent bead. This dimensional change enables light emission in all directions (360-degree illumination) rather than limited to one or two sides as constrained by flat PCB surfaces.
2Reliability
If PCBs with soldering are used, then circuit connections are established, but circuit failures occur due to soldering shorts or false soldering
Solution Approach 1:
The patent extracts the circuit elements (resistors, capacitors, IC chips) from the PCB substrate and integrates them directly into the LED luminous bodies. This extraction eliminates the soldering process between PCB and components, removing the source of soldering-related failures while simplifying the manufacturing process.
Solution Approach 2:
The patent merges the LED, resistor, capacitor, and IC chip into a single integrated LED luminous body. This consolidation eliminates multiple soldering joints and connections, reducing the risk of circuit failures while simplifying the overall manufacturing process through fewer assembly steps.
3Illumination intensity
If double-sided LED attachment on PCBs is used, then illumination coverage is improved, but the PCB area still hinders achieving true 360-degree illumination
Solution Approach 1:
The patent moves from two-dimensional PCB surfaces to three-dimensional spatial distribution of LED luminous bodies around a transparent bead. This dimensional transition allows illumination from all directions including top, bottom, front, back, and sides, achieving true 360-degree coverage without being constrained by planar surface area.
Solution Approach 2:
The patent uses a transparent bead as a flexible, non-rigid structure that allows LED luminous bodies to be positioned in three-dimensional space around it. This replaces the rigid, area-constrained PCB with a flexible volumetric structure that enables omnidirectional illumination.
