Helideck LED Lighting with Dual Assemblies for Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting systems for helicopter landing areas lack a dual system that ensures continuous operation even if some LEDs fail, are difficult to install and maintain, and interfere with helicopter landing and taking off due to projective areas and structural restrictions.
Innovation Solution
An LED lighting apparatus with a dual lighting system that includes separate first and second lighting assemblies, a power supply, and a controller to manage LED operation modes, allowing for continuous operation even if some LEDs fail, easy installation and maintenance, and minimized projective areas to avoid interference with helicopter operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dual lighting system with separate first and second lighting assemblies is implemented, then reliability is improved because the system can keep operating even if some LEDs fail, but device complexity increases due to needing double the number of LEDs, drivers, and control systems
Solution Approach 1:
The lighting system is divided into separate first and second lighting assemblies, each with independent LEDs and drivers. This segmentation allows one assembly to continue operating if the other fails, achieving redundancy without requiring a completely separate backup system. The modular structure enables independent control and maintenance of each assembly.
Solution Approach 2:
The patent combines the dual lighting system into a single integrated apparatus with shared power supply and controller. The first and second lighting assemblies are merged into one cohesive structure that provides both redundancy and simplified overall system management, reducing the complexity that would arise from completely separate systems.
2Ease of manufacture
If separate first and second lighting assemblies are used to form circular and symbol markings, then ease of installation and maintenance is improved because components can be assembled separately, but device complexity increases due to multiple assembly components
Solution Approach 1:
The lighting apparatus is segmented into distinct first and second lighting assemblies that can be manufactured and tested separately before final installation. This allows for modular replacement during maintenance without requiring disassembly of the entire lighting system, significantly improving maintenance ease.
Solution Approach 2:
The lighting assemblies are designed with universal mounting structures and standardized connection interfaces that allow them to be installed on various helideck configurations. The same assembly design can serve multiple functions - forming circular markings, symbol markings, or combination patterns - reducing the need for custom components.
3Object-affected harmful factors
If the lighting apparatus is designed with minimized projective areas to avoid interference with helicopter operations, then safety is improved by preventing interference with landing and taking off, but illumination intensity may be reduced
Solution Approach 1:
The lighting system uses LEDs with specific color characteristics (yellow and green) that provide high visibility to helicopter pilots while emitting light in controlled directions. The lighting assemblies are positioned and oriented to illuminate the helideck surface without creating excessive glare or interference patterns that would affect helicopter operations during landing and takeoff.
Solution Approach 2:
The controller enables dynamic control of the lighting system, allowing adjustment of illumination patterns and intensity based on operational conditions. The system can switch between different operating modes to optimize visibility while minimizing interference with helicopter operations at different times and conditions.
