Replaceable LED Lamp Power Supply Module Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lamps require complete replacement when either the power supply or light module becomes defective, leading to unnecessary waste and increased operational costs, as these components have different lifespans and cannot be easily swapped out.
Innovation Solution
Designing an LED lamp with a replaceable power supply and light module, where the power supply is integrated with the light module and can be easily removed and replaced, allowing for the swapping of either component independently within the tubular body, using a configuration that includes a tubular body, a light module with a circuit board and LEDs, and power connectors that securely couple to the ends of the tubular body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power supply and light module are integrated as a single unit in the LED lamp, then the structural simplicity is improved, but the ease of repair deteriorates because the entire lamp must be replaced when either component fails
Solution Approach 1:
The LED lamp is divided into separate functional modules: a power supply unit and a light module unit, each with independent connectors. This segmentation allows the power supply to be replaced without removing the light module, and vice versa, resolving the contradiction by enabling selective replacement of failed components while maintaining overall structural simplicity through standardized modular interfaces.
2Reliability
If the power supply is soldered to the circuit board for electrical connection, then the electrical connection reliability is improved, but the ease of repair deteriorates because the power supply cannot be easily removed or replaced
Solution Approach 1:
The power supply is extracted from the permanent soldered connection and replaced with a removable connector system. The power supply connector is electrically connected to the circuit board through a socket or terminal block, allowing the power supply to be easily disconnected and replaced while maintaining reliable electrical connections during operation. This resolves the contradiction by separating the reliability requirement (achieved through secure connector engagement) from the repairability requirement (achieved through removable connection).

AI summary
An LED lamp with replaceable power supply includes a tubular body, a light module, a power supply, and two power connectors. The light module is disposed within the tubular body. The light module includes a circuit board and a plurality of LEDs. The LEDs are electrically coupled to the circuit board and are disposed on the bottom side of the circuit board. The power supply is replaceably disposed on the light module and is electrically coupled to the circuit board. The two power connectors are respectively coupled to the two ends of the tubular body and are electrically coupled to the power supply.
