Removable LED Connector Assembly for Modular Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED assemblies require soldering LEDs to circuit boards, making it difficult and costly to replace individual LEDs, as the entire circuit board must be replaced if an LED becomes damaged.
Innovation Solution
An LED connector assembly with a housing that includes a cavity and a latch system to removably receive an LED package, allowing for easy replacement without soldering, using a connector interface to provide power to the LED die through contact fingers that engage a contact pad on the LED package.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LEDs are soldered to circuit board, then electrical connection is secure, but replacement of individual LEDs becomes difficult and costly
Solution Approach 1:
The invention divides the LED assembly into separate modular components: the LED package, the circuit board with circuitry, and the housing. This segmentation allows the LED package to be independently removed and replaced without affecting the circuit board or other components, resolving the contradiction between secure electrical connection and ease of repair.
Solution Approach 2:
The invention introduces a connector as an intermediary component between the LED package and the circuit board. This connector provides reliable electrical connection through contact fingers and contact pads while enabling easy insertion and removal of the LED package, thus maintaining both electrical reliability and repairability.
2Reliability
If entire circuit board is replaced, then damaged LED is replaced, but maintenance time and costs increase
Solution Approach 1:
By segmenting the LED assembly into replaceable LED packages and a permanent circuit board, the invention enables replacement of only the faulty LED package rather than the entire circuit board, significantly reducing maintenance time and costs while restoring LED functionality.
Solution Approach 2:
The invention extracts the LED package from the circuit board through a removable connector interface, allowing the damaged LED package to be taken out and replaced independently. This extraction eliminates the need to replace the entire circuit board, reducing maintenance time and resource waste.
3Ease of repair
If LED package is removably received, then individual replacement is enabled, but electrical connection complexity increases
Solution Approach 1:
The connector serves as an intermediary that simplifies the interface between the removable LED package and the circuit board.通过使用接触指和接触垫的弹簧指结构，它在提供可靠电气连接的同时，保持了简单的插拔操作，平衡了易用性和结构复杂性.
Solution Approach 2:
The connector incorporates a spring finger that automatically makes and maintains electrical contact when the LED package is inserted. This self-service mechanism ensures reliable electrical connection without requiring additional fastening steps or complex alignment procedures, keeping the connector structure simple while enabling easy replacement.

AI summary
An LED connector assembly includes a housing having a cavity formed therein. A connector interface is positioned on the housing to receive electrical wiring from a power source. An LED package is provided having at least one LED die coupled thereto. The LED package is removably received in the cavity of the housing and retained using features in the LED package and housing. The LED package is electrically coupled to the connector interface to provide power to the at least one LED die.
