Pixel-Controlled LED Light String Ordinal Addressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED light string sequencing methods are complex and require pre-programmed address sequence data for each LED, making it difficult to achieve correct illumination effects if the LEDs are not assembled in the correct order.
Innovation Solution
A pixel-controlled LED light string system that includes multiple LED modules with a controller, where each module has an LED drive apparatus that burns an ordinal number based on its connection sequence, allowing light data to be transmitted and identified without pre-programmed address data, enabling correct control of LEDs through a controller that defines target numbers and transmits light data accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-programmed address sequence data is burned for each LED before assembly, then the LEDs can be controlled to light according to light signals, but the assembly process becomes complex and time-consuming requiring precise sequencing
Solution Approach 1:
The patent applies preliminary action by burning the ordinal number into the LED drive apparatus during the manufacturing process before assembly. This pre-programming of a simple ordinal identifier (rather than complex address sequence data) allows the LEDs to be automatically identified and controlled in the correct sequence during operation, eliminating the need for complex pre-assembly sequencing while maintaining control accuracy.
2Adaptability or versatility
If different address sequence data is burned for each LED to enable diverse illumination, then correct lighting control is achieved, but the data transmission time and processing complexity increase
Solution Approach 1:
The patent segments the addressing system into two parts: a simple ordinal number burned into each LED drive apparatus during manufacturing, and sequential light data transmitted during operation. This segmentation allows diverse lighting effects to be achieved through the controller's ability to send different light data sequences to LEDs based on their ordinal positions, while the actual data transmission remains efficient since only lightweight light control data (not complex address data) needs to be transmitted.
3Ease of manufacture
If LEDs are assembled without pre-programmed address data, then assembly becomes simpler, but the LEDs cannot be correctly controlled to achieve diverse illumination effects
Solution Approach 1:
The patent applies self-service by having each LED drive apparatus automatically identify its own position in the sequence through the ordinal number that was burned into it during manufacturing. When light data is transmitted sequentially from the controller, each LED drive apparatus uses its ordinal number to determine when to accept and execute the light control signal, enabling self-identification and self-control without requiring complex external addressing or precise manual assembly sequencing.

AI summary
A pixel-controlled LED light includes a plurality of LED modules and a controller. Each LED module includes at least one LED and a LED drive apparatus. The LED drive apparatus burns an ordinal number according to connection sequence thereof. The controller defines the ordinal number of the LED module as a target number, and sequentially transmits a plurality of light data whose number is greater than or equal to the target number to each of the LED modules. Each of the LED drive apparatuses sequentially receives each of the light data and counts sequence of the light data. If the sequence of the light data is equal to the ordinal number of the LED drive apparatus, the LED drive apparatuses identify the light data, and after identifying the light data, the LED drive apparatuses control the corresponding at least one LED.
