Integrated LED OLED Lighting System Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems often produce high-glare direct light, which can be undesirable, and require additional components like baffles or reflectors to achieve indirect lighting, while also lacking the ability to easily tune color and intensity ratios for different environments and purposes.
Innovation Solution
A lighting system that combines a non-OLED light source on the top face and an OLED light source on the bottom face, with the OLED source configured to block or filter some of the non-OLED light, allowing for tunable color and brightness, and a circuit board to control both sources, providing direct and indirect lighting without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems use direct light sources, then illumination intensity is improved, but glare increases and aesthetic quality deteriorates
Solution Approach 1:
The lighting system is segmented into two distinct light sources: a non-OLED light source for direct illumination and an OLED light source for indirect illumination. This segmentation allows each source to serve a specific function - the non-OLED source provides high-intensity direct light while the OLED source provides diffuse indirect light to reduce glare, resolving the contradiction between illumination intensity and glare reduction
Solution Approach 2:
The OLED light source acts as an intermediary element that converts direct light into diffuse indirect light. By placing the OLED source in proximity to the illumination target, it mediates the harsh direct light from the non-OLED source, transforming it into softer, more aesthetically pleasing indirect illumination that reduces glare while maintaining brightness
2Object-affected harmful factors
If additional components like baffles or reflectors are added to achieve indirect lighting, then glare is reduced, but device complexity increases
Solution Approach 1:
The patent extracts the indirect lighting function from the direct light source by introducing a separate OLED light source dedicated to providing diffuse illumination. This extraction eliminates the need for complex baffles or reflectors that would otherwise be required to modify the direct light, reducing device complexity while achieving glare reduction
Solution Approach 2:
The OLED light source serves multiple functions simultaneously: it provides indirect illumination to reduce glare, enables color and intensity tuning, and eliminates the need for additional optical components like baffles or reflectors. This multi-functionality reduces overall device complexity while achieving the desired glare reduction effect
3Manufacturing precision
If fixed color and intensity ratios are used, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The lighting system incorporates dynamic control capabilities that allow the color and intensity ratios of the two light sources to be adjusted in real-time. This dynamic adjustment enables the system to adapt to different environments and purposes (such as circadian rhythm regulation or aesthetic preferences) while maintaining manufacturing precision through standardized LED and OLED components

Data Source
AI summary
A light unit is provided that includes a frame having a top face and a bottom face, with the bottom face at least partially overlapping the top face in some configurations. A non-OLED light source is disposed on the top face and configured to emit light away from the top face. An OLED light source is disposed on the bottom face and configured to emit light away from the bottom face.
