Surface Mounting Lamp Adhesive Bonding for Side Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surface mounting lamps for aviation and maritime applications require large openings for installation, leading to high installation costs and structural disruption, and often lack side lighting due to opaque flanges and thick covers to withstand stress.
Innovation Solution
A slim and robust surface mounting lamp design featuring a transparent PMMA covering element with embedded lighting units and a junction piece, using adhesive material to distribute mechanical stress and eliminate the need for thick covers and opaque flanges, allowing for side lighting and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal or plastic flange is used to hold the transparent cover, then the lamp body can be securely mounted, but the cover must be made particularly thick to resist high stress, increasing the lamp profile and preventing side lighting
Solution Approach 1:
The patent replaces the mechanical flange-cover fastening system with a chemical bonding system using adhesive material. The adhesive layer interposed between the junction piece and the second face of the covering element eliminates the need for mechanical stress transmission through the cover, allowing the use of thinner covers while maintaining secure mounting. This substitution resolves the contradiction by decoupling the mounting security function from the cover thickness requirement.
2Strength
If a flange is used to mount the lamp, then the lamp can be securely fixed, but the flange constitutes an opaque element that prevents side lighting along the ground
Solution Approach 1:
The patent extracts and removes the flange element from the lamp structure, replacing it with a junction piece that connects to the mounting surface without requiring a peripheral flange. This extraction eliminates the opaque element that blocked side lighting, allowing light to pass laterally along the mounting surface while maintaining secure mounting through the adhesive-bonded junction piece.
3Ease of operation
If large openings are made in the mounting surface for lamp installation, then the lamp can be recessed and fixed, but installation costs increase and structural continuity is significantly impacted
Solution Approach 1:
The patent segments the lamp structure into a separate junction piece that interfaces with the mounting surface, allowing the lamp body to be mounted without requiring large recesses. The junction piece acts as an intermediary element that distributes mounting stresses and enables attachment to the surface with minimal disruption, thereby reducing both installation complexity and structural impact.
4Strength
If adhesive material is used to bond the covering element to the junction piece, then mechanical stress on the covering element is reduced, but the bonding strength must be sufficient to hold the lamp together
Solution Approach 1:
The patent employs adhesive material as a bonding medium that creates a composite structure between the covering element and junction piece. This adhesive layer distributes mechanical stresses uniformly across the bonding interface, reducing peak stresses on the covering element while maintaining reliable attachment. The composite bonding approach ensures both stress reduction and bonding reliability through proper material selection and application.
