Interlaced Data Architecture for Software Configurable Luminaire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices struggle to efficiently manage and interleave image data and lighting control information, leading to high file and memory management overhead, and inefficiencies in delivering both display and general lighting capabilities.
Innovation Solution
A software configurable luminaire with a multi-processor system that separates data into portions containing lighting control information, allowing each portion to control corresponding light pixels for general illumination, and interlaces image and control data for efficient management and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display devices are used to provide both lighting and image output, then image display capability is improved, but lighting efficiency deteriorates
Solution Approach 1:
The patent segments the light source into multiple independently controllable LED types (warm white, cool white, red, green, blue) within each tile. This allows selective activation of specific LED types based on whether general lighting or image display is required, optimizing energy efficiency for each function while maintaining dual functionality.
2Loss of information
If image data and lighting control information are delivered separately, then data accuracy is improved, but data delivery overhead increases
Solution Approach 1:
The patent merges image data and lighting control information into a single interlaced data structure where each pixel contains both display color information and lighting control data. This unified approach eliminates the need for separate data delivery channels, reducing overhead while maintaining complete information integrity through the interlaced format.
3Productivity
If image data and lighting control information are interlaced, then data delivery efficiency is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the interlaced data into distinct fields (image data field and lighting control field) that can be independently processed. The system can selectively extract and process only the relevant portion based on current operational mode, reducing processing complexity while maintaining the efficiency benefits of interlaced data delivery.
4Manufacturing precision
If displays are optimized for image output, then image quality is improved, but general lighting performance deteriorates
Solution Approach 1:
The patent implements universal light-emitting elements (LEDs) that can function in both image display and general lighting modes. By using multiple LED types per tile that can be independently controlled, the system achieves multi-functionality where the same physical structure delivers high-quality images when needed and provides uniform general lighting when required, without sacrificing performance in either mode.
Data Source
AI summary
The examples relate to various representations of data utilized for control of a software configurable lighting device. The software configurable lighting device includes an image display device and a general illumination device. Each data representation includes a pre-defined data structure such that lighting control information and image data may be interlaced within the respective representation.
