Solution Overview
Problem
Existing LED lamp packages lack data input and output pins, complicating the control of luminosity and flashing patterns, especially in larger lamp strings, and do not facilitate easy mounting or wiring layout.
Innovation Solution
Incorporating a control IC with data input and output pins, along with a circuit board and four electric conductivity supports (Vdd, Din, Dout, Vss) exposed outside the package, allowing for external control and flexible wiring, and a socket assembly for easy installation and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If LED lamps use external voltage signals through electric conductivity supports for control, then the control of luminosity and flashing is achieved, but the controller becomes more complicated as the number of LED lamps increases
Solution Approach 1:
The patent divides the control function from the power supply function by adding separate data input and output pins. This segmentation allows each LED lamp to be an independent control unit in a daisy-chain configuration, where control signals are passed sequentially through data pins while power is supplied through separate voltage pins, thereby simplifying the overall controller design.
Solution Approach 2:
The patent introduces data input and output pins as intermediary elements that facilitate communication between LED lamps. These data pins act as mediators that transmit control signals sequentially through the lamp string, enabling decentralized control where each lamp can receive and pass along control instructions without requiring a complex centralized controller.
2Device complexity
If LED lamps lack data input and output pins, then the structure is simpler, but the wiring layout and installation are confined by the number of LED lamps in the string
Solution Approach 1:
The patent makes the LED lamp package universally adaptable by providing both power supply pins (Vdd, Vss) and data pins (Din, Dout) with standardized configurations. This multi-functionality allows the same package design to be used in various wiring scenarios and lamp string configurations, enabling flexible installation layouts without being constrained by the number of lamps.
Solution Approach 2:
The patent enables dynamic reconfigurability of the LED lamp string by implementing data input and output pins that allow sequential signal transmission. This dynamic capability permits the wiring layout to be flexibly arranged in different configurations (series, parallel, or mixed) and allows the system to adapt to varying numbers of LED lamps without requiring redesign of the package structure.
3Device complexity
If LED lamps do not include a control circuit, then the encapsulated electric conductivity supports lack data input and output pins, but diverse control over luminosity and flashing cannot be achieved
Solution Approach 1:
The patent incorporates a control circuit and data pins into each LED lamp package in advance, during the manufacturing stage. This preliminary action embeds the control capability within each individual lamp, enabling diverse control functions (luminosity adjustment, flashing patterns, color changes) to be achieved without requiring external control electronics, thereby providing versatility while maintaining simple overall system architecture.
