Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-power LED lamps generate significant heat, which reduces the service life of cooling fans and the entire lamp due to environmental factors like temperature and moisture, necessitating a more efficient cooling solution without altering the lamp's principal structure.
Innovation Solution
An LED lamp design incorporating a replaceable active cooling module that can be detached and replaced independently of the lamp, featuring a heat dissipation module and a cooling fluid generation system to extend the lamp's service life and reduce replacement costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling fan is used to cool the high-power LED lamp, then the cooling efficiency is improved, but the service life of the fan and the lamp is reduced due to high temperature and moisture in the closed environment
Solution Approach 1:
The lamp is divided into separate functional modules: a lamp body containing the LED and driver, and a detachable active cooling module. This segmentation allows the cooling module to be independently replaced when worn, extending the overall lamp life while maintaining effective cooling through the detachable fan and heat dissipation structure.
Solution Approach 2:
The cooling module is designed to be detachable and replaceable, transforming from a static integrated structure to a dynamic modular system. This allows the cooling components to be renewed independently without replacing the entire lamp, addressing the service life issue while preserving cooling functionality.
2Reliability
If the entire lamp is replaced when the cooling fan reaches end of life, then the lamp performance is maintained, but the replacement cost is high
Solution Approach 1:
By segmenting the lamp into replaceable cooling module and permanent lamp body, only the valuable cooling components need replacement. This reduces material loss and cost compared to replacing the entire lamp, while ensuring the lamp continues to operate at optimal performance with a fresh cooling module.
Solution Approach 2:
The design enables selective discarding of the worn cooling module while recovering and retaining the functional lamp body. This partial replacement strategy reduces waste and cost by preserving the LED, driver, and housing that remain functional, replacing only the consumable cooling components.
