Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple distributed LEDs and complex optical systems are used to achieve large homogeneous lighting surfaces, then lighting coverage is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines multiple LEDs into a single integrated LED module that functions as one unified light source. This module includes an LED array mounted on a circuit board with integrated optical elements, eliminating the need for separate complex optical systems while maintaining large homogeneous lighting coverage.
Solution Approach 2:
The LED module is designed to perform multiple functions simultaneously: it provides broad lighting coverage, integrates optical shaping elements, and serves as a modular replaceable unit. This multi-functionality reduces overall system complexity by consolidating what would otherwise require separate components.
2Area of stationary object
If OLEDs with large emissive surfaces are used for localized lighting, then lighting coverage is improved, but lighting power is insufficient for ambient lighting
Solution Approach 1:
The lighting system is segmented into two distinct functional parts: LED sources for high-power ambient lighting and OLED sources for localized lighting with specific directional control. This segmentation allows each technology to operate in its optimal performance range without compromising overall system capability.
Solution Approach 2:
The patent creates a composite lighting system that integrates two different light source technologies (LED and OLED) with complementary characteristics. The LED provides high power output while the OLED provides directional control and localized lighting, together achieving what neither could accomplish alone.
3Illumination intensity
If OLED emissive surfaces are used solely for light emission, then localized lighting is achieved, but light directionality and concentration capability are lost
Solution Approach 1:
The OLED element is designed to perform dual functions: it emits light for localized illumination and simultaneously acts as a reflective surface to direct and concentrate light from LED sources. This multi-functionality allows the same component to serve both lighting and optical control purposes.
Solution Approach 2:
The OLED surface serves itself by using its own emissive properties to also function as a reflective director for other light sources. The same organic electroluminescent material that emits light when energized also reflects and directs light when in a non-emitting state, eliminating the need for separate directional control elements.
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 hybrid lamp achieves efficient and aesthetically versatile lighting with reduced complexity and cost, utilizing OLEDs to enhance LED light distribution and create desired lighting effects, while being easy to manufacture and adaptable to various forms.
Implementation Method 1
An Organic Light Emission Diode, (OLED) is a light-emitting diode (LED) having a flat electroluminescent emissive layer, formed of an organic film that emits light in response to the transit of electricity.
Implementation Method 2
If the emissive surfaces of the OLED sources are also reflective surfaces, the OLED sources can also be used as reflectors of the light emitted by the associated LED source.
