Plastic LED Housing for Corrosive Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems with light-emitting diodes (LEDs) are prone to corrosion when exposed to corrosive media, such as ammoniacal gases, leading to premature failure in environments like fattening farms.
Innovation Solution
A lighting system with elongated housings made of plastic material and closed or media-tight connecting parts, which significantly reduces the contact of LEDs with corrosive media, allowing the system to be used permanently in corrosive environments without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lighting systems are used in corrosive environments, then initial installation is simple, but corrosion damage occurs leading to premature failure
Solution Approach 1:
A plastic housing acts as an intermediary barrier between the LED light unit and the corrosive environment (ammoniacal gases). The housing completely encloses the LED components, preventing direct contact with corrosive media while still allowing light transmission through translucent or transparent material.
Solution Approach 2:
The patent employs a plastic housing shell that completely encloses the LED light unit. This flexible yet protective shell forms a sealed barrier against corrosive gases and liquids, protecting the internal components while maintaining the lighting function.
2Object-affected harmful factors
If housing is made completely closed to protect against corrosion, then protection against corrosive media is improved, but light emission capability may be reduced
Solution Approach 1:
The housing is made with different local properties: certain areas are translucent or transparent to allow light transmission, while other areas are opaque for structural integrity and maximum protection. This local differentiation maintains both protection and lighting functionality.
Solution Approach 2:
The housing uses composite construction combining opaque structural elements with translucent or transparent sections. This allows the housing to provide complete corrosion protection while maintaining adequate light emission through the translucent portions.
