Networked Lighting Controller Adapting Light Sequences to Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting control network systems face limitations in transferring all lighting control commands due to network bandwidth constraints, leading to delayed or incomplete application of dynamic light effects, which can result in suboptimal user experience.
Innovation Solution
A controller that receives a first sequence of light settings defining a dynamic light effect and adjusts it based on network capacity indications to create a second sequence, optimizing transmission and ensuring timely and effective application without exceeding network capacity, using a processor to convert and transmit light settings via various communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all light settings of a dynamic light effect are transmitted over the network, then the complete light effect can be applied, but network bandwidth limitations cause delays and incomplete transmission
Solution Approach 1:
The controller transmits only a subset of light settings from the original sequence rather than all settings. The processor determines which light settings to transmit based on network capacity, sending enough settings to achieve the desired light effect without overwhelming the network bandwidth, thus balancing completeness with transmission speed
Solution Approach 2:
The sequence of light settings is divided into multiple groups or segments. The controller transmits these segments in batches over time rather than all at once, allowing the network to handle the data flow more efficiently and reducing the overall transmission delay while still achieving the complete light effect
2Loss of time
If the number of light settings is reduced to fit network capacity, then transmission delay is reduced, but the quality and fidelity of the dynamic light effect may deteriorate
Solution Approach 1:
The processor dynamically adjusts parameters of the light settings sequence based on network capacity indicators. When network capacity is limited, it modifies the sequence by removing or consolidating certain light settings while preserving the essential characteristics of the dynamic light effect, thus maintaining fidelity despite reduced data volume
Solution Approach 2:
The system uses network capacity indicators as feedback to dynamically adjust the light settings sequence. The processor continuously monitors network conditions and adapts the transmission strategy accordingly, ensuring optimal balance between transmission speed and light effect quality based on real-time network status
3Productivity
If a constant data stream is used to control lighting devices, then dynamic light effects can be achieved, but network bandwidth is overwhelmed
Solution Approach 1:
Instead of transmitting a constant continuous data stream, the controller uses periodic transmission of light settings batches. The processor sends groups of light settings at regular intervals or based on network conditions, reducing the overall network traffic volume while still achieving dynamic light effects through the sequential application of these periodic updates
