Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lamp beads have limited functionality with only a single light-emitting point, restricted illumination levels, and angles, and are unable to produce adjustable colors, making them inadequate for applications requiring high illumination and multiple colors.
Innovation Solution
LED lamp beads with multiple light-emitting points are created by connecting luminous bodies, such as LED microchips or SMD diodes, in parallel and wrapping them in a package resin with anode and cathode pins, allowing for control of electric current direction through parallel and inverse parallel connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single LED lamp bead is used, then the device complexity is low, but the illumination intensity and color adjustability are limited
Solution Approach 1:
The LED lamp bead is divided into multiple independent light-emitting units, each containing its own LED chip and light guide structure. This segmentation allows each unit to contribute to the overall illumination, thereby increasing total illumination intensity while maintaining a manageable structural complexity through modular design
Solution Approach 2:
Multiple light-emitting units are integrated into a single lamp bead package, combining their light output to achieve higher illumination intensity. The units share common electrical connections and packaging structures, which prevents the device complexity from increasing proportionally with the number of light-emitting units
2Adaptability or versatility
If a single LED lamp bead is used, then the device complexity is low, but the color variety and adjustability are limited
Solution Approach 1:
The lamp bead is segmented into multiple light-emitting units with different LED chip types (e.g., different colors or wavelengths). Each unit can be independently controlled to produce different colors, providing versatile color adjustability while using simple modular segments rather than a complex monolithic structure
Solution Approach 2:
Each light-emitting unit is designed with universal electrical connections and packaging that can accommodate different LED chip types. This multi-functionality allows the same structural framework to support various color combinations, achieving color versatility without increasing structural complexity
3Adaptability or versatility
If multiple LED beads of different colors are used, then the color variety is improved, but the device complexity increases
Solution Approach 1:
Multiple light-emitting units with different colors are merged into a single integrated lamp bead package. This combination provides diverse color variety while using a unified packaging structure, electrical connection system, and control interface, thereby avoiding the increased device complexity that would result from using separate LED beads
Solution Approach 2:
The lamp bead is designed as a multi-functional unit that can produce multiple colors through its integrated light-emitting units. This universal design allows a single device to replace multiple separate colored LED beads, achieving color variety while reducing overall device complexity by consolidating functions into one package

AI summary
LED lamp beads with multiple light-emitting points comprising a certain number of luminous bodies and package resins; in which after at least two luminous bodies are connected in parallel, they are wrapped in a package resin and connected to an anode pin and a cathode pin inserted into the package resin. The present invention structure is simple and has a rational design. By using one-way conductive luminance on the LED luminous bodies, and using parallel and inverse parallel connections on multiple light-emitting points, control of the electric current direction is achieved, and thus the control of the operating modes of luminous bodies and the LED lamp beads with multiple light-emitting points is achieved.
