A method of manufacturing light emitting modules that includes a plurality of light emitting devices with different numbers of elements, where first and second light emitting devices are mounted on a common mounting substrate with identical connection patterns, allowing for the selection of devices to achieve any number of elements from at least three continuous numbers, thereby accommodating various product specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of light emitting elements is adjusted to meet various product specifications, then adaptability to different applications is improved, but manufacturing efficiency and flexibility deteriorate due to inflexible current methods
Solution Approach 1:
The light emitting device is segmented into multiple individual light emitting elements (e.g., 4 elements per device) that can be selectively activated. By controlling which elements are driven, the effective number of light emitting elements can be adjusted (e.g., 4, 3, 2, or 1 element mode), enabling adaptability to different product specifications while maintaining the same physical device structure and manufacturing process.
Solution Approach 2:
The system dynamically adjusts the number of active light emitting elements through control circuitry that can selectively drive different combinations of elements within each light emitting device. This dynamic control allows the same hardware configuration to adapt to varying light output requirements without requiring physical reconfiguration or different device assemblies.
2Adaptability or versatility
If different numbers of light emitting elements are mounted to meet various product specifications, then adaptability is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
A single light emitting device structure with multiple elements serves multiple functions by being capable of operating in different modes (1 element, 2 elements, 3 elements, or 4 elements active). This universal design eliminates the need for different device variants, simplifying manufacturing while maintaining flexibility to meet various light output specifications through selective element activation.
Solution Approach 2:
The system changes operational parameters (which elements are activated) rather than physical parameters (number of mounted elements) to achieve different light output levels. This approach maintains a fixed physical configuration simplifying manufacturing, while achieving adaptability through parameter control - specifically, controlling which of the multiple elements within each device are driven.
3Ease of manufacture
If standard light emitting devices with fixed number of elements are used, then manufacturing simplicity is maintained, but adaptability to various product specifications deteriorates
Solution Approach 1:
Each light emitting device is divided into multiple independent light emitting elements (e.g., 4 elements) that can be individually controlled. This segmentation allows standard manufacturing of devices with a fixed number of elements while enabling flexible adaptation through selective activation of elements, thus maintaining manufacturing simplicity while improving adaptability to various product specifications.
Solution Approach 2:
The system introduces dynamic control capability to standard light emitting devices, allowing the effective number of active elements to be adjusted during operation. This dynamic control layer is added to the manufacturing process without changing the physical device structure, maintaining ease of manufacture while enabling flexible response to different product specifications through software or control circuitry.
