Solution Overview
Problem
Existing OLED lighting apparatuses have a significant non-emission region that reduces emission efficiency, and current coupling methods for OLED modules are either damaging or costly.
Innovation Solution
An OLED lighting apparatus with a magnetic affixing and supporting unit that allows easy replacement of the OLED lighting module, featuring a substrate with an emission and sealing region, a printed circuit board bonded by a sealant, and external input terminals, minimizing the non-emission area and using a metal PCB for improved heat radiation and moisture resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional coupling method is used to attach the OLED lighting module, then the module can be securely mounted, but the coupling process becomes damaging or costly
Solution Approach 1:
The patent replaces conventional mechanical coupling methods (such as clips, adhesives, or welding) with a magnetic coupling system. The socket board includes a magnetic unit that magnetically couples with a conductive member in the OLED lighting module, providing secure mounting without mechanical damage or high cost. This substitution of mechanical fastening with magnetic attraction resolves the contradiction between mounting security and manufacturing ease.
2Reliability
If the non-emission region area is large, then the sealing and electrode coupling functions are adequate, but the emission efficiency decreases
Solution Approach 1:
The patent applies local quality by differentiating the functions of different regions on the substrate body. The substrate includes an emission region optimized for light generation and a sealing region minimized for protective function only. The PCB is designed to bond specifically to the sealing region, concentrating the sealing function in a localized area rather than requiring a large non-emission region throughout. This allows the emission region to maximize light output while the sealed region provides adequate protection.
3Ease of manufacture
If the OLED lighting module has a simple structure, then the manufacturing cost is reduced, but the module replaceability becomes difficult
Solution Approach 1:
The patent segments the OLED lighting system into two independent replaceable components: the OLED lighting module and the socket board. The lighting module contains the substrate body with OLED, sealant, and conductive member, while the socket board contains the magnetic unit and power connection. This segmentation allows the lighting module to be easily replaced by simply detaching and reattaching it to the socket board, maintaining simplicity while enabling replaceability. The magnetic coupling mechanism facilitates this easy replacement without complex fastening systems.
