Lamp socket with ventilation channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
G9 lamp sockets in cooking appliances face overheating issues, which can melt temperature-sensitive foil conductors and break electrical contact, leading to unreliable lighting.
Innovation Solution
Incorporating a ventilation channel within the socket insulator that extends through the material, allowing air exchange between the light source and the outside environment, and a retaining spring design that secures the lamp base while enabling effective heat dissipation through a ventilation gap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the socket insulator uses a solid structure without ventilation, then it provides good mechanical support and electrical insulation, but the lamp base overheats and melts the foil conductors
Solution Approach 1:
The socket insulator is segmented by introducing a ventilation channel that divides the solid structure into separate regions, allowing air flow through the insulator material to cool the lamp base while maintaining structural integrity and electrical insulation properties
Solution Approach 2:
Air is introduced as an intermediary cooling medium through the ventilation channel, acting as a heat transfer mediator between the hot lamp base and the external environment, enabling passive cooling without direct thermal contact with heat sinks
2Reliability
If a ventilation channel is added to cool the lamp base, then the temperature is reduced below critical levels, but the structural integrity and electrical insulation may be compromised
Solution Approach 1:
The ventilation channel is strategically positioned and dimensioned to provide localized cooling only in the critical lamp base region, while the rest of the socket insulator maintains its solid structure for mechanical support and electrical insulation, creating different functional zones within the same component
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
The ventilation channel effectively cools the lamp base, keeping it below critical temperatures for the foil conductors, ensuring reliable and durable lighting in cooking appliances.
Implementation Method 1
the ventilation channel extends through the material of the socket insulator into the base receptacle and allows air to be exchanged between the light source receptacle and the outside environment
Implementation Method 2
Such an air flow can sweep past a lamp base seated in the base receptacle and dissipate the heat generated there
Implementation Method 3
the socket stone in which the G9 lamp is held serves as a heat sink or as a heat sink. This absorbs excess heat from the lamp base and dissipates it
Implementation Method 4
the socket stone in which the G9 lamp is held serves as a heat sink or as a heat sink. This absorbs excess heat from the lamp base and dissipates it
