Irregular LED Mounting for Space-Constrained Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lighting devices face challenges in efficiently utilizing limited mounting area due to their regular and symmetric designs, which restricts light output in dimensionally restricted applications.
Innovation Solution
The use of irregularly shaped LED mounting areas that can be asymmetrical and curved, allowing for more flexible placement and expansion to maximize the available space for light emission, potentially eliminating the need for multiple attachment areas and optimizing light output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If regular and symmetrically shaped LED arrays are used, then manufacturing simplicity is maintained, but area utilization efficiency deteriorates
Solution Approach 1:
The patent applies asymmetry by transitioning from regular, symmetrically shaped LED arrays to irregularly shaped mounting areas that conform to the available space on the lighting device. This allows the LED array to utilize non-traditional geometries (such as triangular, rectangular, or custom shapes) that better fit the device form factor, thereby maximizing area utilization while maintaining manufacturing feasibility through standardized LED components and flexible mounting techniques
2Ease of manufacture
If LEDs are arranged in regular arrays positioned in the middle of the device, then manufacturing simplicity is maintained, but light output efficiency deteriorates
Solution Approach 1:
The patent applies local quality by allowing different regions of the lighting device to have different LED mounting characteristics. Instead of a uniform regular array, the design permits irregularly shaped mounting areas that can be strategically positioned and shaped to optimize light distribution and output efficiency in specific zones, while still using standardized LED components for manufacturing simplicity
3Volume of moving object
If dimensionally restricted device sizes are used, then portability and space efficiency are improved, but available LED mounting area deteriorates
Solution Approach 1:
The patent applies curvature and irregular shapes to the LED mounting area design, allowing the array to conform to the limited space available on compact devices. By using non-linear, curved, or irregular geometric patterns instead of rigid regular arrays, the design maximizes the utilization of available mounting surface area within dimensionally restricted device envelopes, thereby maintaining portability while optimizing light output
