Solution Overview
Problem
Existing lighting systems face challenges in transmitting control signals and data wirelessly within buildings due to spatial conditions that impede wireless transmission, and laying additional cables or using repeaters is complex and expensive.
Innovation Solution
A linear lighting system with a mounting rail and integrated electrical conductors for power and data transmission, utilizing adapters to modulate and demodulate data signals over the electrical conductors, allowing flexible device positioning and local network communication without affecting the building's power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless transmission is used for control signals within buildings, then installation complexity is reduced, but transmission quality and range are impeded by walls and furnishings
Solution Approach 1:
The patent introduces power lines as an intermediary medium for data transmission. Instead of direct wireless communication between control devices and luminaires, data is transmitted by modulating the power supply lines, which penetrate walls and obstacles without obstruction. This mediator approach resolves the contradiction by providing reliable transmission through existing infrastructure that is not blocked by building structures.
2Reliability
If repeaters are used to extend wireless transmission range, then coverage is improved, but system complexity and cost increase
Solution Approach 1:
The patent enables luminaires to serve dual functions: they receive power through the power lines and simultaneously act as data transmission nodes. Each luminaire equipped with a power line communication interface can receive and forward control data, eliminating the need for separate repeater devices. The existing luminaire infrastructure performs the extension function, reducing system complexity while maintaining extended coverage.
3Reliability
If separate cables are laid for data transmission, then transmission reliability is improved, but installation cost and complexity increase
Solution Approach 1:
The patent makes the power supply lines perform multiple functions: delivering electrical power to luminaires and simultaneously serving as data communication channels. By integrating power line communication capabilities into the existing electrical infrastructure, the system eliminates the need for separate data cables, reducing installation costs and complexity while maintaining reliable transmission through the dedicated power line network.
