Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single LED lamp uses a fixed structural design with light-emitting chips mounted on substrates and lenses covering the chips, then the structure is simple and easy to manufacture, but the light emission angle is fixed and cannot be adjusted to meet diverse lighting requirements
Solution Approach 1:
The invention divides a single LED lamp into multiple independent light-emitting chips (first light-emitting chip and second light-emitting chip) with different emission characteristics. The first chip is positioned at the center and the second chip at the periphery, allowing each chip to contribute differently to the overall light distribution. This segmentation enables the lamp to achieve multiple light emission angles and lighting patterns without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The invention applies local quality by positioning light-emitting chips at different locations (center and periphery) with different emission characteristics. The first light-emitting chip at the center provides symmetrical light distribution, while the second light-emitting chip at the periphery provides asymmetrical distribution. This spatial differentiation of emission characteristics allows the single lamp to achieve diverse lighting effects suitable for different scenarios.
2Adaptability or versatility
If multiple LED lamps are used to achieve diverse lighting angles, then lighting requirements can be met, but the device complexity and cost increase
Solution Approach 1:
The invention merges multiple light-emitting chips with different emission characteristics into a single integrated LED lamp structure. By combining the first light-emitting chip (central position) and the second light-emitting chip (peripheral position) within one lamp housing and sharing common optical components (lenses, reflectors), the system achieves the lighting versatility of multiple lamps while reducing the total quantity of devices needed.
Solution Approach 2:
The single LED lamp is designed to perform multiple lighting functions by activating different combinations of light-emitting chips. The lamp can operate in symmetrical mode (first chip only), asymmetrical mode (second chip only), or combined mode (both chips), making it universally applicable to various lighting scenarios such as spotlights, ambient lighting, and directional illumination without requiring multiple specialized lamps.
