Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamps face difficulties in mounting small-sized LED modules without damaging ceramic substrates, and existing methods often break the substrate when creating bolt holes, leading to assembly challenges and reduced service life.
Innovation Solution
The LED lamp design incorporates a base with a heat radiation member featuring a cavity and a fixing frame that presses the LED module onto the cavity's bottom wall, eliminating the need for bolts and preventing substrate breakage, while facilitating heat radiation and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bolt is used to mount the LED module on the heat radiation member, then the mounting strength is improved, but the ceramic substrate will be broken when forming a bolt hole
Solution Approach 1:
The patent removes the bolt and bolt hole from the ceramic substrate by extracting the fastening function to a separate aluminum alloy pressing plate. This eliminates the harmful drilling process that causes substrate breakage while maintaining secure mounting through the pressing plate's clamping action on the LED module's aluminum substrate.
Solution Approach 2:
The patent introduces an aluminum alloy pressing plate as an intermediary component between the heat radiation member and the LED module. This pressing plate serves as a mediator that provides the mounting function without requiring holes in the ceramic substrate, thus protecting substrate integrity while achieving secure fastening.
2Volume of moving object
If the LED module is made small-sized, then the compactness is improved, but it becomes difficult to form a bolt hole for mounting
Solution Approach 1:
The patent extracts the fastening function from the LED module itself by using a separate aluminum alloy pressing plate. This allows the LED module to maintain its small size without compromising mounting capability, as the pressing plate handles all fastening operations externally.
Solution Approach 2:
The patent uses an aluminum alloy pressing plate that can be easily formed and discarded if needed, replacing the need for complex bolt hole formation in the precious ceramic substrate. The pressing plate serves as a sacrificial or replaceable component that simplifies manufacturing.
3Ease of operation
If the LED module is loosely mounted, then the assembly ease is improved, but the heat radiation efficiency deteriorates
Solution Approach 1:
The patent merges the mounting function with the heat radiation function by integrating the aluminum alloy pressing plate to simultaneously secure the LED module and ensure thermal contact. The pressing plate's dual role achieves both easy assembly and efficient heat radiation without requiring separate mechanisms.
Solution Approach 2:
The pressing plate is pre-formed with the appropriate shape and mounting features before assembly. This preliminary preparation allows for easy assembly while ensuring that the pressing plate will properly contact both the LED module and heat radiation member to maintain efficient thermal conduction during operation.
