Solution Overview

Problem

Existing light emitting diode (LED) lamp string systems require numerous power and signal transmission lines for control, leading to increased complexity and cost, especially as the number of modules increases, and current address data is fixed during manufacturing, making it inconvenient for management and assembly.

Innovation Solution

An LED lamp and string with a burnable function, where the LED driving apparatus can receive a burn start signal and address data to write local address data into its memory, reducing the need for multiple control lines and allowing address data to be changed post-manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If parallel-type connection is used to control multiple LED lamp string modules, then each module can be controlled independently, but the amount of control lines and address lines increases proportionally, leading to increased complexity and cost

Engineering Contradiction:
ImproveIndependent control capabilityVSAvoidNumber of control lines
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines address data and control signals into a single data transmission line. The LED driver circuit integrates the address register and control logic, allowing multiple modules to be addressed independently through a single shared data line rather than requiring separate address lines for each module.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The data transmission line serves multiple functions: it transmits both address data and control signals to multiple LED lamp string modules. The LED driver circuit is designed to handle both addressing and control operations through the same communication interface, reducing the overall number of required lines.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If address data is burned into the LED driver apparatus during manufacturing, then the address is fixed, but this makes warehouse management and assembly inconvenient due to inability to change addresses

Engineering Contradiction:
ImproveAddress data stabilityVSAvoidAddress reconfigurability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent implements a dynamic address configuration system where the LED driver circuit can load and switch between different address data sets. The address register is designed to accept external address input during operation rather than being permanently fixed, allowing addresses to be changed based on installation requirements while maintaining stable operation once configured.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows address data to be prepared and loaded in advance during the assembly process or initial setup phase, before the LED lamp string is installed. This preliminary configuration action enables flexible address assignment without requiring permanent burning during manufacturing, facilitating easier warehouse management and assembly operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

A light emitting diode lamp with a burnable function includes at least a light emitting diode and a light emitting diode driving apparatus with the burnable function. The light emitting diode driving apparatus is electrically connected to the light emitting diode. The light emitting diode driving apparatus includes a positive contact and a negative contact. The light emitting diode driving apparatus receives a burn start signal sent through the positive contact and a burn address data sent through the positive contact. The light emitting diode driving apparatus is configured to burn the burn address data into the light emitting diode driving apparatus after the light emitting diode driving apparatus receives the burn start signal.
