LED Light Fixture With Ground Mount Pins For Par 36 Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED replacement lamps for Par 36 halogen and incandescent well lights lack efficient installation methods and are prone to damage, requiring a plastic housing and snap-fit installation, which is not suitable for all applications and can be damaged easily.
Innovation Solution
The DYNAMIC DUO LED light fixture provides a waterproof crimp or wire nut connection for electrical installation and can be used as a stand-alone fixture with ground mount pins, allowing for easy installation, repositioning, and angling, with a design that includes heat dissipating vent holes and a moisture-resistant body to prevent corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED replacement lamps use the same legacy Par 36 halogen dimensional lamp size and plastic housing with snap-fit installation, then they are compatible with existing fixtures, but they are prone to damage and require complex housing structures
Solution Approach 1:
The patent merges the LED lamp module with a metal well housing into a single integrated fixture. The LED module is permanently mounted within the metal housing, eliminating the need for separate plastic housings and snap-fit mechanisms. This integration provides structural strength while maintaining compatibility with existing Par 36 fixtures through the standardized metal housing interface.
Solution Approach 2:
The patent replaces the plastic housing with snap-fit installation mechanism with a metal housing and screw-terminal electrical connection system. The metal housing provides superior mechanical strength and durability, while the screw-terminal connections offer more reliable electrical connections compared to fork connectors.
2Illumination intensity
If halogen and incandescent lamps are used in Par 36 fixtures, then they provide adequate illumination, but they consume high wattage and have short lamp life
Solution Approach 1:
The patent changes the fundamental operating parameters by replacing incandescent/halogen filament technology with LED technology. LEDs operate at significantly lower voltages and currents to produce the same or better illumination output, achieving 80-90% energy savings while extending lamp life from 2,000-5,000 hours to 50,000+ hours.
Solution Approach 2:
The patent transitions from thermal radiation (incandescent) and halogen cycle (halogen) light generation mechanisms to electroluminescence (LED) light generation. This phase transition in the underlying physics enables dramatically improved energy efficiency and longevity while maintaining illumination quality.
3Ease of operation
If LED replacement lamps use fork connector and terminal screw connections, then electrical connection is established, but the connection is not waterproof and requires additional housing protection
Solution Approach 1:
The patent merges the electrical connection terminals with the waterproof metal housing structure. The screw terminals are mounted within the sealed housing environment, and the housing itself provides the waterproof barrier. This integration eliminates the need for separate waterproofing measures while maintaining ease of electrical connection.
4Ease of manufacture
If LED lamps are laid on the ground without proper mounting, then installation is simple, but they are subject to damage and not UL approved
Solution Approach 1:
The patent segments the lighting system into a self-contained modular fixture unit that includes the LED module, metal housing, mounting pins, and electrical connections as an integrated assembly. This segmentation allows the fixture to be installed as a complete unit directly into the ground or existing well housing, providing both simplicity and durability without requiring complex separate components.

AI summary
An LED light fixture that replaces a par 36 lamp includes a body casting having an LED mounting area with an outer perimeter surrounded by an outer ring, and a shroud covering a portion of the outer perimeter of the LED mounting area. The body casting has elongated slots that extend between the LED mounting area and the outer ring. The outer ring has internally threaded openings that extend through the outer ring and that are spaced from one another around the outer ring. The light fixture includes ground mounting pins having first ends with external threads that are adapted to mesh with the internally threaded openings in the outer ring. The pins may be affixed for ground mounting and removed for disposing the light fixture in a well housing disposed in the ground. An LED circuit board containing one or more LEDs overlies the LED mounting area.
