Innovation Solution
A light-emitting device design featuring a support with high thermal conductivity, a power supply connector with integrally-formed metal members, and a bare chip light-emitting element connected via wires, all covered by a protective and light-diffusing cover member, which simplifies assembly and reduces part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lighting devices use multiple separate components (connector, wiring board, heat spreader), then reliability and ease of repair are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the connector body, heat dissipation structure, and electrical connection components into a single integrated power supply connector. This merging reduces the number of separate parts (eliminating the need for separate wiring boards and heat spreaders) while maintaining reliable electrical and thermal connections through the integrated design.
2Ease of manufacture
If the number of parts is reduced to lower manufacturing cost, then manufacturing cost and device complexity are reduced, but ease of repair and reliability may worsen
Solution Approach 1:
The integrated connector combines multiple functions (electrical connection, heat dissipation, structural support) into one component, reducing part count and manufacturing complexity while maintaining reliability through careful design of the integrated structure.
Solution Approach 2:
The integrated connector is designed with distinct functional zones: the first portion for electrical connection (with contact portions and wiring), the second portion for heat dissipation (with heat dissipation fins), and the third portion for structural support. This internal segmentation allows each function to be optimized independently within the unified structure.
3Adaptability or versatility
If AC power is converted to DC power using a power supply circuit, then compatibility with semiconductor light-emitting elements is improved, but device complexity and energy consumption increase
Solution Approach 1:
The power supply connector is designed to accept AC power input while integrating the necessary rectification and voltage regulation functions. The connector includes contact portions for phase and neutral lines, and the integrated structure provides both electrical connection and power conversion capabilities in a single component, reducing overall system complexity.
