Track Lighting Power Distributor with Insulated Series Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current track lighting systems lack the ability to control individual light fixtures independently, as they are typically connected in parallel, leading to excessive heating and limited power supply, which restricts independent control and efficient thermal management.
Innovation Solution
The system allows light fixtures to be connected in series through a power distributor and electrical interface with insulated supply channels, enabling independent control of each fixture by using jumpers to complete series circuits, reducing heat-related issues and increasing power management efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light fixtures are connected in parallel on a single channel, then all light fixtures can be powered simultaneously, but independent control of individual light fixtures is not possible
Solution Approach 1:
The patent divides the track lighting system into multiple independent channels (first channel, second channel, etc.), each capable of carrying series or parallel connections. This segmentation allows different groups of light fixtures to be controlled independently through different channels, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent employs jumper wires that can be selectively installed or removed to dynamically reconfigure the electrical connections between light fixtures. This dynamic configuration capability allows the system to switch between series and parallel connections on different channels, enabling flexible independent control while maintaining a relatively simple base structure.
2Temperature
If multiple light fixtures are connected in parallel, then power distribution is simplified, but excessive heating occurs before circuit breaker activation
Solution Approach 1:
By dividing the system into multiple channels, the patent distributes the power load across separate pathways. Each channel can be configured with series connections that reduce current draw and heat generation, while the multi-channel architecture maintains overall power distribution capability, thus managing temperature without sacrificing power supply capacity.
Solution Approach 2:
The patent changes the electrical connection parameters by allowing selective configuration of series versus parallel connections on different channels. Series connections increase voltage drop and reduce current, thereby reducing I²R heating losses, while still delivering the required power to multiple fixtures through the multi-channel architecture.
3Reliability
If light fixtures are connected in series on multiple channels, then independent control and thermal management improve, but the electrical connection structure becomes more complex
Solution Approach 1:
The patent segments the electrical interface into multiple standardized channels with consistent connection points. This segmentation enables independent control of each channel while maintaining a relatively uniform and manageable structural pattern, reducing the overall complexity compared to a fully custom multi-channel design.
Solution Approach 2:
The patent introduces jumper wires as intermediary components that simplify the electrical interface. These jumpers act as mediators that can be easily installed or removed to configure series or parallel connections, reducing the complexity of the electrical interface structure while enabling flexible independent control of light fixtures on different channels.
4Power
If AC voltage track lighting systems use parallel connections, then power delivery is sufficient, but the current is limited by circuit breakers causing excessive heating
Solution Approach 1:
The patent changes the electrical connection configuration from purely parallel to a hybrid of series and parallel connections across multiple channels. This parameter change allows the system to operate at lower currents with series connections, reducing I²R heating losses, while maintaining adequate power delivery capacity through the multi-channel architecture that can be configured based on power requirements.

AI summary
A track lighting apparatus includes a frame, a power distributor, and an electrical interface. The frame includes a track configured to support a plurality of light fixtures. The power distributor electrically connects two or more inputs to two or more supply channels. Each supply channel is electrically insulated from other supply channels. The electrical interface includes electrical components that form two or more supply channels such that the supply channels form an incomplete series circuit that includes two or more breaks. A light fixture or a jumper is electrically connected across each break to complete the series circuits.
