Dual-Surface OLED Luminaire for Compact Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luminaires require multiple light sources to achieve different lighting types, leading to bulkier designs and inefficiencies in space usage and lighting effects, while existing solutions fail to effectively utilize chronobiological effects for improved performance capabilities.
Innovation Solution
A luminaire with an organic light-emitting diode (OLED) featuring two opposing light emission surfaces with different color temperatures and directions, allowing for space-saving dual-light emission, where blue or cold-white light is used for indirect lighting and warm-white light for direct lighting, leveraging a fixing apparatus for adjustable mounting and reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources are used to achieve different lighting types, then lighting versatility is improved, but device size and complexity increase
Solution Approach 1:
The patent segments the light emission function by dividing the OLED into two opposing light emission surfaces (first and second light emission surfaces) that emit light in different directions and colors. This allows a single illuminant to provide both indirect lighting (through the ceiling) and direct lighting (downward) with different color temperatures, resolving the contradiction by achieving lighting versatility without increasing luminaire size through multiple separate light sources
Solution Approach 2:
The patent makes the single OLED illuminant universal by enabling it to perform multiple lighting functions simultaneously. The first light emission surface provides indirect lighting with first color temperature while the second light emission surface provides direct lighting with second color temperature. This multi-functionality allows one component to replace what would traditionally require multiple separate light sources, thereby reducing overall device size while maintaining lighting versatility
2Adaptability or versatility
If multiple light sources are used to achieve different lighting types, then lighting versatility is improved, but device complexity increases
Solution Approach 1:
The OLED is segmented into two functional surfaces with different emission characteristics. The first light emission surface is configured to emit light in a first direction with first color temperature for indirect lighting, while the second light emission surface emits light in a second direction with second color temperature for direct lighting. This segmentation within a single component achieves lighting versatility without the structural complexity of integrating multiple separate light sources, drivers, and control systems
Solution Approach 2:
The single OLED illuminant is designed to be universal by incorporating both indirect and direct lighting capabilities within one component. This eliminates the need for multiple separate illuminants and their associated mounting structures, electrical connections, and control systems, thereby reducing device complexity while maintaining the ability to provide different lighting types

Function Achieved in This Case
The luminaire generates distinct lighting types using a single OLED, enhancing performance capabilities by initiating chronobiological effects, while maintaining a compact design and adjustable lighting distribution.
Implementation Method 1
the illuminant comprises an organic, light-generating region. In particular, the illuminant can then be an organic light-emitting diode or light-emitting electromechanical cells (LEC)

AI summary
A luminaire for general lighting includes an illuminant having a first light emission surface and a second light emission surface. The illuminant includes an organic, light-generating region. The first light emission surface and the second light emission surface are arranged at two mutually opposite main surfaces of the illuminant. A first light emerges at the first light emission surface during the operation of the illuminant, and a second light emerges at the second light emission surface during the operation of the illuminant. The first light and the second light differ from one another with regard to color and/or color temperature. The first light and the second light leave the luminaire in mutually different emission directions.
