Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If LED illumination devices use traditional lighting control protocols (like DALI), then communication reliability is maintained, but data transmission rate is limited and network scalability is constrained
Solution Approach 1:
The patent combines two communication protocols (traditional lighting control protocol and high-speed communication protocol) into a single LED illumination device, allowing the device to operate on both DALI and DALI-2 networks simultaneously. This merging enables the device to maintain reliable control communication while also supporting high-speed data transmission and improved network scalability.
Solution Approach 2:
The LED illumination device is designed with multi-functionality by incorporating dual protocol support. The device can function as both a traditional DALI endpoint and a DALI-2 bridge, enabling it to communicate on both network types and facilitating seamless integration into evolving lighting control systems with enhanced scalability and data transmission capabilities.
2Ease of operation
If LED illumination devices are connected in standalone configuration, then device simplicity is maintained, but communication efficiency and network integration capability are limited
Solution Approach 1:
The patent merges communication functionality by integrating both traditional lighting control protocol interface and high-speed communication protocol interface into a single LED illumination device. This combination enables the device to operate efficiently in networked configurations while maintaining relatively simple implementation through shared hardware resources and unified control logic.
3Quantity of substance
If multiple devices are added to lighting control network using traditional protocols, then network coverage is expanded, but data traffic increases and communication bandwidth becomes insufficient
Solution Approach 1:
The patent segments communication traffic by separating control data transmission (using traditional lighting control protocol) from high-speed data transmission (using high-speed communication protocol). This segmentation allows multiple devices to be added to the network while routing different types of data through appropriate protocols, reducing overall data traffic burden on the control network and improving communication efficiency.

AI summary
An LED based illumination device includes a receiver and a transmitter for communications adhering to a lighting control communications protocol and a high speed communications protocol. The LED based illumination device may be part of a lighting control network, wherein the data transmission rate of the high speed communications protocol is more than twice that of the lighting control communications protocol. The lighting control network may be coupled to a digital communications gateway, including a digital communications interface configured to be coupled to a network operating in accordance with an internet protocol and a lighting control network interface coupled to the lighting control network. A processor determines a summary status value of the LED based illumination device based on information stored in memory of the digital communications gateway. The digital communications gateway may periodically transmit the time of day to the LED based illumination device over the lighting control network.
