Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems face bandwidth limitations when deploying highly dynamic lighting content, requiring large amounts of configuration data to be transmitted between the system controller and lighting devices, which is insufficient for rendering complex effects.
Innovation Solution
A lighting system utilizing a mesh network where each lighting device communicates illumination state information with neighbors, allowing local configuration and synchronization to deploy dynamic lighting effects without initial configuration data from the system controller, using seed devices or random configuration information to propagate effects across the network.

1Manufacturing precision
If large amounts of configuration data are transmitted from the system controller to lighting devices to render highly dynamic lighting content, then the lighting effects can be deployed accurately, but the bandwidth between the system controller and lighting devices becomes insufficient
Solution Approach 1:
The system divides the configuration data into two segments: global effect parameters transmitted from the system controller, and local illumination state information exchanged between neighboring lighting devices. This segmentation reduces the amount of data that must traverse the limited bandwidth links between the controller and devices.
Solution Approach 2:
Lighting devices autonomously determine their own configuration by receiving illumination state information from neighboring devices and locally calculating their required settings. This self-configuration mechanism eliminates the need for the system controller to transmit complete configuration data to each device, thereby reducing bandwidth requirements.
2Adaptability or versatility
If the system controller transmits complete configuration data to each lighting device, then all lighting effects can be deployed, but the communication bandwidth becomes a bottleneck
Solution Approach 1:
The configuration data is segmented into global effect parameters (transmitted once from controller to network) and local illumination state information (exchanged locally between devices). This allows diverse lighting effects to be supported without proportionally increasing the data volume transmitted through bandwidth-constrained links.
Solution Approach 2:
The system transitions from a centralized configuration model (controller transmits to all devices) to a distributed configuration model (devices exchange information locally). This dimensional shift in the communication architecture reduces the data volume traversing the bottleneck links while maintaining effect variety.
3Adaptability or versatility
If lighting devices operate independently without location knowledge, then deployment flexibility is improved, but the ability to create coordinated dynamic lighting effects is limited
Solution Approach 1:
Lighting devices receive illumination state information as feedback from neighboring devices and use this feedback to locally determine their own configuration. This feedback mechanism enables coordinated lighting effects to emerge organically from local interactions, maintaining flexibility while achieving synchronization.
Solution Approach 2:
Each lighting device autonomously determines its configuration based on received illumination state information from neighbors. This self-service approach allows devices to operate independently without centralized control while still achieving coordinated effects through local interaction and inference.
