Bitmap Lighting Control for Synchronized Performance Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting devices in performance halls, such as sports stadiums and concert venues, are difficult to control systematically, making it challenging to create cohesive lighting patterns or media facades due to their individual control and the presence of seating that obstructs uniform lighting.
Innovation Solution
A system where one light emitting device is designated as a pixel in a bitmap, allowing for the control of multiple devices as pixels, with a control console device generating and transmitting data packets in real-time to change lighting states, and incorporating a master device to correct color errors in the data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light emitting devices are individually controlled, then each device can operate independently, but it becomes difficult to produce systematic patterns or shapes
Solution Approach 1:
The patent merges multiple individually controlled light emitting devices into a unified bitmap-based control system. By organizing devices into a grid structure where each device corresponds to a pixel coordinate, the system achieves systematic pattern generation while maintaining individual device operability through coordinate-based addressing.
Solution Approach 2:
The control system implements universality by using a single bitmap data structure to control all light emitting devices regardless of their individual positions. The same control protocol and data format can address any device in the grid, enabling systematic control while accommodating individual device operations through the universal pixel coordinate system.
2Illumination intensity
If light emitting devices are used in performance halls with seats, then lighting can be provided, but it becomes difficult to produce media facade effects due to obstructed space
Solution Approach 1:
The patent transitions from traditional spatial arrangement constraints to a two-dimensional bitmap coordinate system. By mapping light emitting devices to pixel coordinates (x, y) in a grid, the system overcomes the physical obstruction issue and enables media facade effects through logical positioning rather than physical line-of-sight requirements.
Solution Approach 2:
The system creates virtual copies of the performance space through bitmap representation. Each light emitting device is represented as a pixel in the bitmap, allowing the control system to generate visual patterns and media facade effects in the digital domain that are then reproduced by the physical devices, bypassing physical space constraints.
3Manufacturing precision
If color palette information is transmitted for each production scene, then accurate color control is achieved, but data packet size increases
Solution Approach 1:
The patent applies preliminary action by pre-defining color palettes and storing them in the control system. Instead of transmitting complete color information for every pixel in each scene, the system references pre-established color palettes using index values, thereby reducing data transmission requirements while maintaining precise color control.
Solution Approach 2:
The patent introduces color palette index values as an intermediary between the control system and the actual color values. Rather than transmitting full color data (RGB values) for each pixel, the system transmits compact index references that point to predefined colors in a palette, significantly reducing data packet size while preserving color accuracy.
Data Source
AI summary
The inventive concept includes a control console device to generate and transmit a data packet for a light emitting operation for each production scene for a performance, and a plurality of light emitting devices to receive the data packet from the control console device and to perform the light emitting operation in the data packet. The light emitting device emits light in a first color corresponding to first group information for a first production scene, which is contained in the data packet, based on group information for each production scene which is previously stored.
