Surface Mount Lamp Transparent Cover Adhesive Sealing
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 disruptions, and they often lack side lighting due to opaque flanges that prevent lateral illumination.
Innovation Solution
A slim and robust surface mounting lamp design featuring a transparent PMMA covering element with integrated lighting units and sockets, sealed with adhesive material, allowing for side lighting without mechanical stress on the covering element, and using a junction piece with connecting portions for secure attachment without mechanical fastening to the mounting surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal or plastic flange is used to hold the transparent cover, then the cover can be securely fixed, but the cover must be particularly thick to resist high stress and the flange prevents side lighting
Solution Approach 1:
The patent removes the traditional metal or plastic flange from the lamp structure. Instead, the transparent cover is directly fixed to the lamp body using adhesive or chemical bonding, eliminating the opaque flange that blocked side lighting. This extraction of the flange component resolves the contradiction by allowing light to pass through the entire perimeter of the cover while maintaining structural integrity through alternative fixation methods.
Solution Approach 2:
The patent replaces the mechanical flange-based fixation system with a chemical bonding system (adhesive or epoxy). This substitution eliminates the need for a thick cover to resist mechanical stress from a flange, as the adhesive provides secure bonding without requiring the cover to be overly thick.同时，this replacement removes the opaque flange that prevented side lighting, allowing light to pass through the cover's entire perimeter.
2Ease 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 into modular components: a lamp body, a transparent cover, and a junction piece for electrical connections. This segmentation allows the lamp to be assembled from separate parts and installed through a smaller opening in the mounting surface, rather than requiring a large opening to accommodate the entire lamp structure. The modular design facilitates easier installation with minimal structural disruption.
Solution Approach 2:
The patent transitions from a traditional lamp design that requires recessed installation (three-dimensional embedding) to a surface-mounted design where the lamp sits atop the mounting surface. The junction piece extends through the mounting surface for electrical connections, while the main lamp body remains above the surface. This dimensional change allows installation through a smaller opening and preserves the structural continuity of the mounting surface.
3Illumination intensity
If the lamp is raised relative to the flange to enable side lighting, then lateral illumination is achieved, but the lamp becomes even more protrusive
Solution Approach 1:
By removing the flange entirely, the patent eliminates the obstacle that previously required the lamp to be raised for side lighting. The transparent cover can now extend to the very edge of the lamp body, allowing light to pass through the entire perimeter at the lowest possible profile. This extraction enables side lighting without increasing lamp protrusion.

Function Achieved in This Case
The design achieves a slim, robust, and easy-to-install lamp that provides side lighting while minimizing structural impact and installation costs, with a sealed and watertight structure that can withstand high compression loads.
Implementation Method 1
the retaining means are of a chemical type, that is, defined by a layer of adhesive material (for example, epoxy glue) or sealing material

AI summary
A surface mounting lamp includes a covering element of a transparent material and having a first face, which in use is directed outwards away from a mounting surface of the lamp, and a second face opposite the first face and provided with at least one socket for housing lighting elements. A lighting unit is sealably connected to the covering element, facing the inside of the socket and includes a plurality of lighting elements, each housed in the socket. The lamp also includes a junction piece connected to the covering element and having a connecting portion engageable with the mounting surface of the lamp to fix the position thereof, and a retaining mechanism interposed between the junction piece and the second face of the covering element and connecting the covering element to the junction piece.
