LED Lamp Assembly via Integrated Reflecting Barriers

Solution Overview

Problem

The assembly of LED lamps is complicated due to the need for bonding or locking of the lamp holder, circuit board, and optical elements, leading to increased installation costs and difficulties in automated production.

Innovation Solution

A lighting lamp design featuring a strip lamp holder with a mounting cavity, a circuit board, a light source, an optical lens, and reflecting barriers, where the optical lens and strip lamp holder are connected via a buckle structure, and the reflecting barriers press against the circuit board to fix it, eliminating the need for locking parts and simplifying assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bonding or locking is used to fix the circuit board to the lamp holder, then the assembly is more secure, but the assembly steps become complicated and installation costs increase

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The circuit board is integrated directly into the lamp holder body, eliminating the need for separate bonding or locking operations. The mounting cavity in the lamp holder directly receives and secures the circuit board through the integrated structure, reducing assembly steps while maintaining security.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lamp holder structure itself provides the fixing function through its integrated mounting cavity, eliminating the need for additional fastening components or operations. The structure serves both as the holder and the fixing mechanism simultaneously.
