Address Mapping for Random LED Light Strings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing point-controlled LED light strings face inefficiencies in production due to the need for precise ordering of LED lights and sequential address coding, which complicates assembly and maintenance, especially when dealing with hundreds or thousands of lights.
Innovation Solution
A manufacturing method that randomizes the address coding of LED lights, allowing them to be connected in series or parallel without considering their order, using a DC power supply controller with consecutively arranged address registers that correspond one-to-one with the lights, enabling automated assembly and simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED lights are assembled according to the order of unique address codes, then the control system can properly identify and control each LED, but the production efficiency is greatly reduced when there are hundreds or thousands of LED lights
Solution Approach 1:
Instead of having the controller follow the physical sequence of LEDs to assign addresses, the patent inverts the approach by allowing LEDs to be assigned addresses based on their physical connection order, regardless of their address code values. The controller reads address codes and dynamically maps them to the current LED position in the daisy-chain connection sequence, separating the physical assembly order from the logical address assignment.
2Productivity
If a two-level address lookup method is used to rewrite second-level address codes, then production efficiency is improved, but the secondary coding process still affects overall production efficiency
Solution Approach 1:
The patent extracts the address code rewriting process from the LED lights themselves and moves it to the controller. Instead of modifying address codes in the LEDs during assembly, the controller reads the original address codes and generates the appropriate control signals based on the actual connection sequence, eliminating the need for secondary coding operations on the LED modules.
3Adaptability or versatility
If the main controller reads and writes each LED device to update the address table, then the system can adapt to new controllers, but the production efficiency is reduced due to the time-consuming process
Solution Approach 1:
The patent performs the address mapping configuration in advance during the assembly process. When LEDs are connected in daisy-chain, the controller automatically detects the connection sequence and establishes the address mapping between physical positions and address codes. This preliminary configuration eliminates the need for time-consuming address table updates when controllers are replaced, as the new controller inherits the existing mapping relationships.

AI summary
A point-controlled LED light string and a manufacturing method thereof, the light string comprises a DC power supply controller integrated with a plurality of address registers; and LED lights each with a unique address code. The LED lights form a light string with an address code random method, according to a sequence in which the LED lights are connected and arranged in the light string, associating the LED lights one to one with the corresponding address registers, and each of the address registers stores a corresponding address code of a corresponding LED light. The method comprises the steps of selecting LED lights each with a unique address code by an address code random method randomly to form a light string, storing the address codes of the LED lights in address registers arranged in an orderly manner, and associating the address registers one to one with corresponding LED lights.
