Solution Overview

Problem

There is no LED driver available that operates in an AC input and constant output mode and complies with the KNX protocol specification, which is necessary for efficient control and management of LED illumination systems.

Innovation Solution

A device for driving light-emitting diodes (LEDs) that directly uses a KNX protocol signal, comprising an address transceiver, a processor, and a power supply, which generates a driving signal to directly control the LED module without converting the KNX protocol signal into another protocol like DALI, thereby reducing costs and complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If KNX protocol signal is converted to another protocol (e.g., DALI) to drive LED module, then compatibility with existing LED drivers is improved, but system complexity and cost increase due to protocol converters

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the KNX protocol processing capability directly into the LED driver device by integrating an address transceiver and control circuit that can interpret KNX protocol signals. This eliminates the need for separate protocol converters and directly enables KNX compatibility in the LED driver, resolving the contradiction by combining multiple functions into a single integrated device

Inventive Principle:

Solution Approach 2:

The LED driver is designed with multi-functionality to directly process multiple types of control signals including KNX protocol signals, DALI signals, and other standard control protocols. The control circuit can adaptively recognize and process different protocols, making the device universally compatible without requiring additional conversion components

AI summary

A device for driving light-emitting diodes (LEDs) includes an address transceiver, a processor, and at least one power supply. The address transceiver stores a communication address and receives a Konnex (KNX) protocol signal carrying a driving address. The address transceiver generates a driving signal when the driving address corresponds to the communication address. The processor, electrically connected to the address transceiver, receives the driving signal and generates a power starting signal according to the driving signal. The power supply, electrically connected to the processor and at least one light-emitting diode (LED) module, receives the power starting signal and uses the power starting signal to drive the LED module.
