Integrated LED Lamp Socket with Heat Sink for Compact Retrofit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps with integrated ballast and Edison sockets are too large for retrofitting and are prone to theft, and high-quality compact fluorescent lamps are often replaced with incandescent lamps, necessitating a solution that addresses size constraints and theft risks for modern LED light sources.
Innovation Solution
A lamp design featuring a socket body with an integrated heat sink that dissipates operating heat from an LED light source, allowing for compact LED installations and reducing theft risk through non-standard base systems, with the socket body itself serving as a heat sink and potentially incorporating external cooling ribs or threaded sections for enhanced heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If compact fluorescent lamps with integrated ballast are used, then the lamp size is reduced and retrofitting becomes easier, but the lamps become more prone to theft and replacement with inferior lamps
Solution Approach 1:
The patent merges the socket body and LED light source into a single integrated unit that cannot be separated without destruction. This integration eliminates the separate replaceable lamp component, making theft and unauthorized replacement impractical while maintaining compact dimensions suitable for retrofitting existing fixtures.
2Volume of moving object
If LED light sources are used with integrated operating electronics, then the lamp size can be reduced to match incandescent lamp dimensions, but effective heat dissipation becomes more challenging
Solution Approach 1:
The socket body is merged with the LED light source and integrated operating electronics into a single compact unit. The socket body itself functions as a heat sink with thermal management capabilities, enabling effective heat dissipation from the LED and electronics while maintaining small overall dimensions comparable to traditional incandescent bulbs.
3Reliability
If non-standard base systems are used, then theft risk is reduced, but compatibility with existing lamp fixtures becomes more limited
Solution Approach 1:
The integrated LED light source with socket body is designed to be compatible with multiple existing fixture types including Edison sockets and compact fluorescent lamp fixtures. The universal design allows the same integrated unit to replace different lamp types in various fixtures while maintaining theft resistance through its non-separable construction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures long service life for LED light sources by effective heat dissipation, maintains compact size comparable to incandescent lamps, and reduces theft risk due to non-standard base systems, while ensuring professional assembly and heat transfer quality.
Implementation Method 1
the socket body carries an LED lamp and is provided with an integrated heat sink that dissipates the operating heat from a heat-conducting element of the LED light source
Implementation Method 2
the socket body is provided at least in sections with external cooling ribs running in the circumferential direction. This arrangement of cooling ribs promotes air circulation between the ribs
