Track Lighting Wireless Controller for Multi-Fixture Addressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless lighting control systems are costly due to the need for individual wireless receivers for each controllable device, which can cost around $200 each.
Innovation Solution
A track lighting system with integrated wireless receivers that can be positioned anywhere along the track, using a single receiver to control multiple fixtures, reducing the need for individual receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual wireless receivers are provided for each controllable device, then each device can be independently controlled, but the system cost increases significantly
Solution Approach 1:
The patent introduces a central controller as an intermediary device that manages multiple controllable devices. The central controller receives control signals and distributes them to individual devices through the track system, eliminating the need for each device to have its own wireless receiver. This mediator approach maintains independent control capability while significantly reducing system cost.
Solution Approach 2:
The track system is designed with multi-functionality, serving both as a power distribution network and a data communication network. The same track infrastructure that delivers electrical power to devices also carries control signals from the central controller, consolidating multiple functions into a single system and reducing overall complexity and cost.
2Measurement precision
If each device has its own wireless receiver, then control precision is maintained, but installation and maintenance complexity increases
Solution Approach 1:
The system segments control functionality between the central controller and the controllable devices. The central controller handles complex control logic and signal processing, while individual devices only need simple receivers or even just power connections. This segmentation maintains control precision at the central level while simplifying individual device complexity and easing installation and maintenance.

AI summary
A track lighting system having power conductors and data conductors is provided with a wirelessly operated controller unit which is supplied with power from the power conductors and controlled by a remote transmitter. The controller unit supplies addressable controllable signals to the data conductors of the system for effecting individual control of a plurality of output devices. The new system eliminates the need in conventional systems for providing each of the plurality output devices with individual wireless receivers.
