Lighting Network Display Nodes for Dynamic Information Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting networks lack sufficient bandwidth to support the transmission of real-time image data, limiting their ability to display dynamic information in a meaningful way at remote locations within or outside premises.
Innovation Solution
A lighting network system that uses information display nodes connected to the existing lighting infrastructure, equipped with processors and projectors, to generate and project dynamic information by combining received data with locally stored image data, without requiring additional network infrastructure or bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time image data is transmitted over the lighting network, then the information display capability is improved, but the network bandwidth is insufficient
Solution Approach 1:
The patent segments the information display system into multiple distributed information display nodes positioned throughout the premises, each capable of independently receiving and processing data. This segmentation allows the limited network bandwidth to be shared across multiple display locations simultaneously, resolving the contradiction between information display capability and network bandwidth constraints.
Solution Approach 2:
The patent applies preliminary action by pre-loading static image data into the memory of information display nodes before runtime. This preparation eliminates the need to transmit large image files in real-time, allowing the network to only carry small dynamic data updates. This resolves the bandwidth limitation while maintaining full information display capability.
2Quantity of substance
If additional network infrastructure is installed to support image data transmission, then the bandwidth is increased, but the system complexity and cost increase
Solution Approach 1:
The patent makes the existing lighting network universal by enabling it to serve dual purposes: its original lighting control function and new information display function. The information display nodes utilize the same network infrastructure for both purposes, eliminating the need for separate dedicated display networks and reducing overall system complexity.
Solution Approach 2:
The patent applies self-service by having information display nodes autonomously generate complete display images by combining pre-loaded static image data with received dynamic data locally. Each node independently processes and renders displays without requiring centralized image processing or additional network bandwidth, allowing the system to scale without proportional infrastructure increases.
3Loss of information
If static image data is transmitted in real-time, then the information completeness is improved, but the bandwidth consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-loading complete static image data into the local memory of each information display node during installation or off-peak times. This preparation ensures that when dynamic information arrives, the node can immediately combine it with the pre-loaded static data to generate complete, information-rich displays without requiring real-time transmission of large image files, thus maintaining information completeness while minimizing bandwidth consumption.
Data Source
AI summary
Disclosed is a system for displaying dynamic information from a remote information source at one or more locations within or outside a premises. The system includes a lighting network configured to enable communication of data to and from a plurality of lighting devices and at least one information display node positioned within or outside the premises and connected to the lighting network. The information display node includes a processor configured to receive dynamic information transmitted over the lighting network from a remote source, memory for locally storing image data, and a projector. The processor is configured to generate display data using a combination of the received dynamic information and the stored image data and the projector is configured to project the display data in a visually perceptible form in proximity to the information display node.
