Problem
Existing meteor shower lamps are bulky and costly due to the large number of packaged LED lamp beads required for a flowing light effect, making them unsuitable for compact sizes and high production costs.
Innovation Solution
A lamp bulb design featuring a lamp base, shell, and stem assembly with a PCB light source panel and metal supporting wires, allowing for integrated light-emitting chip groups with a conductive pattern and IC controllers to achieve a flowing light effect, reducing volume and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packaged LED lamp beads are used to achieve a flowing light effect, then the light effect is natural and smooth, but the lamp volume becomes large and production cost increases
Solution Approach 1:
The patent extracts the LED lamp beads from their packaged form and integrates the light-emitting chips directly onto a PCB board. This removes the unnecessary packaging volume while retaining the functional light-emitting capability, thereby reducing the overall lamp volume while maintaining the flowing light effect.
Solution Approach 2:
The patent merges the LED lamp beads with the PCB board by directly mounting the light-emitting chips onto the board. This integration combines multiple components (PCB, LED chips, mounting structure) into a single unified structure, eliminating the need for separate packaged beads and reducing volume.
2Reliability
If packaged LED lamp beads are used to achieve a flowing light effect, then the light effect is natural and smooth, but the production cost becomes high
Solution Approach 1:
The patent removes the packaged LED lamp beads and uses bare light-emitting chips directly on the PCB. This eliminates the packaging manufacturing step and reduces material costs, thereby lowering production cost while maintaining the flowing light effect through direct chip integration.
Solution Approach 2:
The patent uses inexpensive light-emitting chips that can be directly mounted on the PCB without requiring expensive packaged LED beads. These chips are cost-effective and can be easily replaced or adjusted during manufacturing, reducing overall production cost while achieving the desired light effect.
3Reliability
If a large number of LED lamp beads are integrated to achieve a flowing light effect, then the light effect is natural and smooth, but the carrier area becomes large
Solution Approach 1:
The patent transitions from a linear arrangement of packaged LED beads along a long strip to a two-dimensional distribution of light-emitting chips on a PCB board. This dimensional change allows for compact arrangement of multiple chips within a smaller area while maintaining the flowing light effect through controlled chip activation patterns.
Solution Approach 2:
The patent combines multiple light-emitting chips onto a single PCB board, merging what would otherwise require a long linear carrier strip. This integration consolidates the carrier function into a compact PCB structure, reducing the overall carrier area while supporting multiple light sources for the flowing effect.
