Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp designs with LEDs and light guide plates face limitations in design options due to the need for a minimum frame width to avoid bright surroundings and complex installation processes.
Innovation Solution
A lamp design featuring LEDs arranged along the side surface of a light guide plate, with a cover element that covers the LEDs and frame, allowing for a narrower frame and simplified assembly through a mechanical connection, using an elastic cover element and latching mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame width is reduced to improve design options, then the design flexibility improves, but the LEDs become visible and the light homogeneity deteriorates
Solution Approach 1:
The invention extracts the LED covering function from the frame element and assigns it to a separate cover element. This allows the frame to be narrowed for better design flexibility while the cover element independently performs the LED covering and light homogenization function, resolving the contradiction between frame width reduction and light homogeneity maintenance.
Solution Approach 2:
The invention segments the previously combined frame functions into separate components: the frame element for structural support and the cover element for LED covering and light homogenization. This segmentation allows independent optimization of each component, enabling narrow frame design while maintaining light homogeneity through the dedicated cover element.
2Adaptability or versatility
If the frame width is reduced, then the design flexibility improves, but the mechanical protection of LEDs deteriorates
Solution Approach 1:
The invention extracts the LED protection function from the frame element and assigns it to the cover element. This allows the frame to be narrowed for design flexibility while the cover element provides the necessary mechanical protection for the LEDs, resolving the contradiction between frame width and protection capability.
3Stability of the object's composition
If the LEDs are attached inside the frame to the light guide plate, then the structural stability improves, but the installation complexity increases
Solution Approach 1:
The invention merges the LED attachment to the light guide plate with the cover element integration. The LEDs are attached to the light guide plate's rear surface, and the cover element simultaneously covers both the LEDs and the light guide plate connection area, creating a unified assembly that simplifies installation while maintaining structural stability.
4Illumination intensity
If a cover element is added to cover the LEDs, then the light homogeneity and design flexibility improve, but the device complexity increases
Solution Approach 1:
The cover element is designed to perform multiple functions simultaneously: covering the LEDs to ensure light homogeneity, providing mechanical protection, and serving as a mounting structure for the light guide plate. This multi-functionality justifies the additional component by consolidating several protective and optical functions into a single element.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances design flexibility by allowing a narrower frame while improving installation ease and homogeneity of light emission, enabling a more efficient and aesthetically pleasing lighting solution.
Implementation Method 1
a light guide plate (4) with a front surface (5) that is planar in a first approximation, a rear surface (6) and a peripheral side surface (7) which connects the front surface with the rear surface, wherein the LEDs are arranged along the side surface (7) in such a way that the light is coupled into the light guide plate (4). The lamp is designed in such a way that the light is then emitted at least partially via the front surface (5).
Implementation Method 2
The cover element is preferably made of an elastic material. This makes assembly easier. In particular, the cover element can consist of an elastomer, preferably a thermoplastic elastomer.

AI summary
The LED-lamp has LEDs producing a light. A light guide plate (4) includes an edge-side side surface, which connects a front surface (5) with a back surface (6). The LEDs are arranged along the side surface such that light is coupled into the guide plate. The LED-lamp is designed such that light is partially delivered over the front surface. A frame element (8) is arranged around the guide plate and the LEDs. The lamp is designed such that a cover strip (10) of a cover element (9) covers the LEDs, and the frame element does not cover the LEDs in a projection normal to the front surface. The cover element is made of thermoplastic elastomer.
