Replaceable LED Light Source Units for Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED lighting devices have integral light source modules, requiring the entire module to be replaced if any LED chip is damaged, making maintenance inconvenient, especially for devices like plant growth lamps that need multiple modules.
Innovation Solution
A lighting device design where each light source unit is an independent replaceable component, with a circuit switching component connected to an external power supply and a conductive member for easy power connection, allowing individual replacement of damaged units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If integral light source modules are used with multiple LED chips on the same substrate, then the device structure is simplified and manufacturing is easier, but the entire module must be replaced when any LED chip is damaged, increasing maintenance complexity and reducing ease of repair
Solution Approach 1:
The patent divides the light source module into independent replaceable units, each containing a substrate with one or more LED chips. This segmentation allows individual units to be replaced without replacing the entire module, resolving the contradiction by maintaining manufacturing simplicity while enabling selective replacement of only damaged components.
2Reliability
If the entire light source module is replaced when an LED chip is damaged, then reliability is restored, but time is lost during replacement and resources are wasted on replacing functional components
Solution Approach 1:
By segmenting the module into independent replaceable units, the patent enables rapid replacement of only the damaged unit rather than the entire module. This significantly reduces replacement time while restoring reliability, as only the affected segment needs to be exchanged.
Solution Approach 2:
The patent enables selective discarding of only the damaged LED chip or unit while recovering and retaining the functional portions of the module. This prevents waste of functional components and reduces the frequency of replacements needed.
3Illumination intensity
If multiple light source modules are used in devices like plant growth lamps, then the lighting requirements are met, but replacement becomes especially inconvenient and productivity is reduced
Solution Approach 1:
The patent applies segmentation to create standardized, independently replaceable light source units that can be quickly exchanged in multi-module devices. This maintains the required illumination intensity through multiple units while dramatically improving maintenance efficiency, as each unit can be replaced without affecting others.
