Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting technologies, such as incandescent and fluorescent lamps, face issues with energy efficiency and color rendering, while LED lighting methods using blue and yellow phosphors have limited luminous efficiency due to low efficiency in red and green wavelength bands.
Innovation Solution
An OLED lighting apparatus with a tiling structure is developed, utilizing two flexible OLED panels with bent bezel and light emitting areas, fastened by a fastening member, and equipped with a light guide plate and optical member to ensure seamless emission without a bezel area, enhancing light distribution and visual characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple OLED panels are tiled together to form a large area lighting apparatus, then the lighting area is increased, but the bezel area becomes visible and degrades visual characteristics
Solution Approach 1:
The lighting apparatus is divided into multiple separate OLED panels that are tiled together to form a large area structure, allowing the lighting area to be increased while maintaining modular flexibility in the patent
Solution Approach 2:
The bezel area is extracted and removed from the OLED panel structure, allowing the light emitting area to extend to the edges of the panel and eliminating the visual degradation caused by visible bezels when panels are tiled together in the patent
2Use of energy by moving object
If the light emitting area is extended to the edge of the panel, then the lighting efficiency is improved, but the structural integrity and ease of connection become compromised
Solution Approach 1:
A flexible buffer layer is introduced at the edge of the OLED panel to provide structural support and protection where the light emitting area extends to the panel edge, maintaining structural integrity while preserving lighting efficiency in the patent
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
The solution provides a seamless OLED lighting structure that maintains high visual quality by ensuring light emission at boundary portions, eliminating the bezel area and thus preventing visual characteristic degradation.
Implementation Method 1
a light guide plate which is arranged on the fastening member and guides a light emitted from a bent side of the first flexible OLED panel upwardly
Implementation Method 2
an optical member arranged on the fastening member, and configured to emit a light at a boundary portion where the first and second flexible OLED panels contact

AI summary
An OLED lighting apparatus of a tiling structure in a seamless structure without a bezel area is discussed. The OLED lighting apparatus includes a first flexible OLED panel and a second flexible OLED panel. The first flexible OLED panel which a bezel area and one side of a light emitting area are bent, and the second flexible OLED panel which a bezel area is bent, are fastened by a fastening member, and a light guide plate and an optical member are arranged on the fastening member. As a result, the OLED lighting apparatus tiles by using the fastening member at a boundary portion to which the first and second flexible OLED panels contact, and the light guide plate and the optical member are applied on the fastening member, so that a light can be emitted even at the boundary portion to which first and second flexible OLED panels contact.
