LED Retrofit System for HID Fixture Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing High Intensity Discharge (HID) lighting systems are inefficient and have a short lifespan, making them costly to maintain and requiring significant downtime for retrofitting, while also generating excessive heat and energy consumption.
Innovation Solution
A method and system for retrofitting HID lighting fixtures with Light Emitting Diode (LED) modules, involving measuring and designing LED arrays to fit within the existing fixture's lens opening, using a power converter to adapt power sources, and reusing existing fixtures to minimize downtime and costs, allowing for customization of light dispersion and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If HID lighting systems are used, then high illumination intensity is achieved, but energy consumption is excessive and heat generation is high
Solution Approach 1:
The patent changes the fundamental operating parameters of the lighting system by replacing HID bulbs with LED modules that operate at different electrical and thermal parameters, achieving the same illumination intensity with lower energy consumption and heat generation
Solution Approach 2:
The patent substitutes the HID lighting mechanism (gas discharge, arc lamp) with a solid-state LED lighting mechanism, eliminating the need for ballasts and high-voltage electrical systems while maintaining illumination performance
2Loss of energy
If HID fixtures are retrofitted with LED modules, then energy efficiency is improved, but significant downtime is required for the retrofitting process
Solution Approach 1:
The patent segments the retrofit process into modular components (LED modules with integrated mounts and wiring) that can be independently installed and replaced, enabling quick swapping without complex disassembly of the entire fixture
Solution Approach 2:
The patent incorporates preliminary design features including pre-assembled LED modules with integrated mounting hardware and wiring configurations that match existing HID fixtures, allowing for rapid installation without on-site customization
3Adaptability or versatility
If custom LED arrays are designed to fit existing fixtures, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates universal LED modules with standardized mounting interfaces and wiring configurations that can be adapted to multiple different HID fixture types, eliminating the need for custom designs for each fixture while maintaining adaptability through the use of existing fixture components such as brackets and lenses
