Innovation Solution
An LED lighting system utilizing an insulation displacement connector (IDC) to connect LED downlights in parallel across a low voltage pair of wires, allowing for easy addition or removal of downlights without affecting the light output, and incorporating a driver that provides a constant voltage and frequency, eliminating the need for complex wiring and professional installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LED downlights are hard-wired into high voltage mains using DC or low voltage drivers, then the lighting system provides stable operation, but the installation process becomes complex and requires professional electricians
Solution Approach 1:
The system divides the lighting installation into modular components: a centralized driver unit and multiple independent LED downlight modules. Each downlight is a self-contained unit that can be independently installed and connected, simplifying the overall installation process while maintaining system stability.
Solution Approach 2:
The patent introduces a specialized connector as an intermediary component between the driver and LED downlights. This connector simplifies the electrical connection process, eliminating the need for complex hard-wiring into high voltage mains and reducing installation complexity while maintaining reliable electrical connection.
2Adaptability or versatility
If multiple LED downlights are installed with complex hard-wiring, then the system can provide multiple light sources, but the installation cost increases due to requirement of professional electricians
Solution Approach 1:
The lighting system is segmented into independent, modular downlight units that can be easily added or removed. Each module connects through simple interfaces, allowing users to expand the number of light sources without incurring additional professional installation costs.
Solution Approach 2:
The connector design provides universal compatibility across multiple downlight units and driver configurations. A single connector type works for all installations, eliminating the need for custom wiring for each additional light source and reducing overall installation costs.
3Ease of operation
If LED downlights are connected in parallel across low voltage wires using insulation displacement connectors, then the installation process is simplified, but ensuring stable voltage and frequency requires a constant voltage driver
Solution Approach 1:
The insulation displacement connector serves as an intermediary that simplifies the physical and electrical connection between driver and LED modules. This connector enables parallel wiring configuration that naturally provides stable voltage distribution, reducing the complexity burden on the driver while maintaining ease of installation.

AI summary
A lighting system includes an LED downlight mountable to a ceiling and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The IDC connects the downlight to a wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding IDC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.
