Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standardized luminaires are used for all locations, then procurement and inventory management are simplified, but the illumination uniformity across diverse spatial geometries deteriorates
Solution Approach 1:
The patent implements dynamic control of light distribution by enabling electronic adjustment of the light distribution curve through parameterization. The luminaire can adapt its illumination pattern in real-time to match different spatial geometries and lighting requirements, transforming a static device into a dynamic one that responds to environmental conditions.
Solution Approach 2:
The invention changes the parameters of light distribution by allowing electronic modification of the luminous flux distribution curve. Through parameterization, the luminaire can adjust intensity and direction of light in different solid angle regions, enabling the same physical device to serve multiple lighting scenarios without physical modification.
2Adaptability or versatility
If multiple luminaire types are used for different spatial conditions, then illumination uniformity improves, but procurement and storage complexity increases
Solution Approach 1:
The patent creates a universal luminaire design that can perform multiple lighting functions through electronic parameterization. A single luminaire type can be electronically configured to serve different spatial geometries and illumination requirements, replacing the need for multiple specialized luminaire models in the inventory.
Solution Approach 2:
By enabling electronic modification of light distribution parameters, the invention allows one luminaire design to adapt to various spatial conditions. The parameterizable light distribution curve enables the same physical device to be optimized for different environments, reducing the variety of hardware needed.
3Adaptability or versatility
If light distribution is adjusted mechanically by moving lenses, then light intensity in specific directions changes, but the system complexity and adjustment precision deteriorate for non-symmetrical distributions
Solution Approach 1:
The patent replaces mechanical lens adjustment mechanisms with electronic control of the light distribution curve. Instead of physically moving components to change light direction, the system uses electronic parameterization to modify the luminous flux distribution, eliminating complex mechanical systems while achieving superior control precision.
Solution Approach 2:
The invention substitutes mechanical adjustment systems with electronic control methods. By parameterizing the light distribution curve electronically, the system achieves precise control over light intensity in different solid angle regions without the complexity, wear, and limited precision of mechanical lens movement mechanisms.

AI summary
Luminaire for stationary installation in an indoor or outdoor space with a light-emitting surface which emits light from several LEDs (10), at least one optic (2) associated with the light-emitting surface which deflects the luminous fluxes of the LEDs (10) differently in different sub-areas of the optic (2), and an electronic interface for controlling the luminaire, wherein the control is configured to change the luminous fluxes of the LEDs (10) in the different sub-areas of the optic (2) so that a ratio of luminous intensities of the light emitted by the optic (2) changes relative to each other in at least two different solid angle regions which are not rotationally symmetric to each other.
