Solution Overview
Problem
Existing LED flush-mounted light fittings for suspended ceilings are complex and costly to install due to the need for additional mounting rails, increasing installation time and complexity.
Innovation Solution
A planar strip light design with the LED panel's light-emitting side arranged perpendicular to the reflector, reducing installation depth, and featuring fasteners for direct mounting to plasterboard constructions, eliminating the need for modifying sub-constructions and allowing for a cost-effective, time-saving installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional mounting rails are used to support LED tubes in suspended ceilings, then the structural stability is improved, but the device complexity and installation time increase considerably
Solution Approach 1:
The patent combines the mounting rail function and support function into a single integrated plasterboard construction system. The strip light is directly mounted to the plasterboard construction using fasteners, eliminating the need for separate additional mounting rails. This merging of functions reduces the number of components and simplifies the overall mounting structure while maintaining structural stability.
Solution Approach 2:
The plasterboard construction is designed to serve multiple functions: it provides structural support, acts as the mounting surface, and eliminates the need for separate mounting rails. The fasteners directly attach the strip light to the plasterboard construction, which universally handles both support and mounting tasks, reducing system complexity.
2Strength
If additional mounting rails are attached first to support LED tubes, then the structural support is improved, but the installation time is lengthened
Solution Approach 1:
The plasterboard construction is pre-prepared with appropriate mounting surfaces and structures during its fabrication process. This preliminary preparation eliminates the need for on-site assembly of separate mounting rails, allowing the strip light to be directly fastened to the pre-prepared plasterboard construction, significantly reducing installation time.
Solution Approach 2:
The support function and mounting function are merged into a single integrated system. The plasterboard construction itself provides the structural support that would otherwise require separate mounting rails, allowing direct fastening of the strip light and eliminating the two-step process of installing rails first and then mounting the lights.
3Shape
If the power supply unit is arranged inside the strip light, then the integration is improved, but the installation depth increases preventing flush mounting
Solution Approach 1:
The power supply unit is extracted from the strip light assembly and positioned separately in the available space within the plasterboard construction. This separation allows the strip light itself to maintain a compact, shallow profile that enables flush mounting with the plasterboard surface, while the power supply unit occupies separate volume that does not interfere with the aesthetic finish.
4Illumination intensity
If the LED panel's light-emitting side is arranged parallel to the reflector, then the light output is maximized, but the installation depth increases
Solution Approach 1:
The LED panel is oriented with its light-emitting side perpendicular to the reflector instead of parallel, changing the dimensional arrangement. This perpendicular orientation allows the light to be coupled laterally from the reflector, maximizing light output while minimizing the installation depth in the direction perpendicular to the plasterboard surface, enabling flush mounting.
