Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting technologies require a separate decorating film and illuminating panel, leading to increased thickness, manufacturing costs, energy consumption, and reduced integration in flat lighting devices due to the need for additional assembly processes to achieve decorative patterns.
Innovation Solution
An illuminating panel with a supplemental layer containing a light-shielding portion and a transparent portion integrated between the substrate and the light source layer, allowing for in-built light shaping and eliminating the need for a separate decorating film, thereby enhancing integration and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a separate decorating film is used to achieve decorative patterns, then the aesthetic appeal is improved, but the device thickness and manufacturing complexity increase
Solution Approach 1:
The patent merges the light-shielding function with the decorative pattern function into a single integrated layer. The conductive layer contains both signal lines for electrical connectivity and light-shielding portions that form decorative patterns, eliminating the need for a separate decorating film and reducing manufacturing complexity while maintaining aesthetic appeal
Solution Approach 2:
The conductive layer serves multiple functions simultaneously: it provides electrical signals to light-emitting components, blocks light in specific areas to create decorative patterns, and integrates both functionality into one layer, thereby reducing the overall device complexity and assembly requirements
2Shape
If a separate decorating film is used, then light shaping is achieved, but the number of assembly processes increases
Solution Approach 1:
The light-shielding portions are integrated directly into the conductive layer, combining light shaping functionality with the electrical signal transmission function. This integration eliminates the need for separate assembly of a decorating film, thereby reducing the number of assembly processes and improving productivity
3Reliability
If multiple separate components are used, then functional requirements are met, but integration is reduced
Solution Approach 1:
The patent integrates light-shielding portions and signal lines into a single conductive layer, reducing the number of separate components while maintaining all necessary functional requirements. This improves integration and reduces device complexity
Solution Approach 2:
The conductive layer is designed to perform multiple functions simultaneously - electrical signal transmission and light blocking for decorative patterns - thereby reducing the number of components needed and improving overall integration while meeting all functional requirements

AI summary
An illuminating panel includes a light source layer comprising a plurality of light- emitting components, a conductive layer disposed over a light-emitting side of the light source layer, and an insulating layer sandwiched between the light source layer and the conductive layer. The conductive layer comprises signal lines, each configured to drive emission of lights from the light-emitting components, and further comprises a light-shielding portion, configured to block one portion of the lights from the light source layer from passing therethrough. The light-emitting components are configured such that those unshielded or partially shielded by the light-shielding portion is electrically coupled to one signal line to emit lights, and those completely shielded by light-shielding portion is not electrically coupled to the signal lines and thus not able to emit lights. A lighting device containing an illuminating panel is further disclosed herein.
