Masking-Layer Lighting Control for Dynamic Crowd Display Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting devices struggle with individual control, making it difficult to create systematic lighting patterns and effective cheering effects in performance environments like sports stadiums or concert halls, and are limited by wireless bandwidth constraints during simultaneous data broadcasting.
Innovation Solution
A lighting effect directing method using a masking layer to control multiple light emitting devices, involving determining device coordinates, receiving predefined maps and control packets, and emitting light based on object and masking layer information to dynamically express direction shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual control of light emitting devices is used, then device autonomy is maintained, but systematic lighting patterns and cheering effects cannot be created
Solution Approach 1:
The patent introduces a control unit as an intermediary between the light emitting devices and the control system. This control unit receives control signals containing direction object information and mask information, processes them locally, and generates appropriate control signals for each light emitting device. This mediator enables systematic lighting patterns without requiring complex individual control of each device, resolving the contradiction between adaptability and device complexity.
2Productivity
If multiple light emitting devices are controlled simultaneously through broadcasting, then collective control is achieved, but wireless bandwidth is limited by data processing time
Solution Approach 1:
The patent segments the control approach by dividing the direction object into multiple partial objects and using multiple masking layers to cover different regions. Each light emitting device only needs to process information relevant to its specific position and assigned partial objects, rather than processing all direction object data. This segmentation reduces the data processing burden on each device while maintaining collective control, resolving the contradiction between productivity and data transmission volume.
3Illumination intensity
If comprehensive direction object information is transmitted to all devices, then complete lighting coverage is achieved, but wireless bandwidth consumption increases
Solution Approach 1:
The patent applies local quality by assigning different control responsibilities to different light emitting devices based on their positions. Each device receives and processes only the direction object information and mask information relevant to its specific location and assigned partial objects. This localized information processing ensures complete lighting coverage while minimizing wireless bandwidth consumption, as each device transmits and processes only necessary data for its local region.
