LED Driver with Burnable Address Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting diode (LED) lamp systems require numerous power and signal transmission lines for control, leading to increased complexity and cost, especially as the number of LEDs increases, and current address data is fixed during manufacturing, making it inconvenient for management and assembly.
Innovation Solution
Incorporating a light emitting diode driving apparatus with a burnable function that allows for the burning of local address data after a burn start signal, enabling flexible address data programming and reducing the need for multiple control lines and address lines by using a first signal with pulse signals to drive LEDs based on matching address data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local address data is burned into the light emitting diode driving apparatus during manufacturing, then the address data is fixed and reliable, but it cannot be changed and makes warehouse management and assembly inconvenient
Solution Approach 1:
The patent makes the address data dynamic by allowing it to be changed after manufacturing. The light emitting diode driving apparatus includes a microcontroller that can receive and update address data through communication interfaces, transforming the static burned-in address into a dynamic, programmable parameter that can be adjusted during operation or maintenance.
Solution Approach 2:
The patent changes the parameter of address data from fixed to variable. By implementing software-based address storage in the microcontroller rather than hardware burning, the address data becomes a changeable parameter that can be modified through communication protocols, enabling flexible reconfiguration without physical changes to the apparatus.
2Manufacturing precision
If numerous power transmission lines and signal transmission lines are used to control LED colors and intensities, then control precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple control functions into a single integrated system. The microcontroller combines power management, address identification, and lighting control functions, allowing communication with multiple LEDs through a unified digital interface rather than separate analog control lines for each function.
Solution Approach 2:
The patent replaces the mechanical wiring system with a digital communication system. Instead of using separate physical transmission lines for power and control signals, the system uses digital communication protocols where data packets carry both power management commands and control information, reducing physical connections while maintaining control precision.

AI summary
A light emitting diode lamp with a burnable function includes a light emitting diode and a light emitting diode driving apparatus. The light emitting diode driving apparatus receives a burn start signal and a burn address data sent through a first contact. The light emitting diode driving apparatus burns the burn address data as a local address data into the light emitting diode driving apparatus after the light emitting diode driving apparatus receives the burn start signal. A first signal is a plurality of pulse signals, and comprises a lighting data and an address data. The light emitting diode driving apparatus compares the address data with the local address data, and drives the light emitting diode to light, glimmer or flash colorfully or sparklingly, or light fade-in and fade-out, based on the lighting data if the address data is the same with the local address data.
