Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring methods for lighting systems, such as Daisy Chain, Loop, and 'T' methods, result in excessive voltage drop and inconsistent light output due to varying voltage across fixtures, requiring additional parts, labor, and time to minimize these issues.
Innovation Solution
The Equalizer Hub, a wiring manifold that distributes voltage evenly to each lamp by connecting the homerun wire from the power source directly to the fixtures without intermediate connections, reducing voltage drop and allowing for easy addition and troubleshooting of fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If Daisy Chain wiring method is used, then installation is simple, but voltage drop becomes excessive
Solution Approach 1:
The wiring system is segmented into multiple parallel paths instead of a single series path. Each light fixture is connected to both the homerun wire and the run wire, creating separate current paths that reduce cumulative voltage drop while maintaining ease of installation.
2Loss of energy
If Loop Method is used, then voltage drop decreases at mid-point, but extra parts and labor are required
Solution Approach 1:
The invention extracts the voltage compensation function from the complex Loop Method and implements it through a simpler parallel wiring configuration. The homerun wire provides a direct return path for each fixture, eliminating the need for additional looping wires while achieving voltage equalization.
3Loss of energy
If T Method is used, then voltage drop lessens with shorter runs, but more labor and time are spent
Solution Approach 1:
The invention merges the advantages of the T Method (shorter wire runs) with the ease of installation of the Daisy Chain Method. By combining parallel wiring with a centralized homerun connection point, the system achieves short effective runs while maintaining simple installation procedures.
4Ease of operation
If traditional wiring methods are used, then lights receive different voltage, but inconsistent light output results
Solution Approach 1:
The parallel wiring configuration with homerun connections creates equipotential points at each fixture. All fixtures are connected to the same voltage reference through the homerun wire, ensuring uniform voltage distribution and consistent light output while maintaining ease of wiring.

AI summary
This invention is directed toward a method for wiring lighting systems, primarily low voltage, landscape lighting systems. The inventive method operates to equalize voltage drop across such lighting systems. The inventive method involves running a home run wire from a power source or transformer to a wiring hub. Two or more light fixtures having equal length wire leads are connected to the home run wire in the wiring hub. Each of the light fixtures are then arranged in the landscape lighting system around the wiring hub. Uniform voltage drop is achieved through the creation of equal distances between multiple light fixtures and a common power source. The common home run wire and equal length wire leads results is an equal distance from a common power source to each light fixture in the configuration.
