Light Emitting Module Layout for Thermistor Light Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting modules do not effectively protect components such as thermistors from external light and other environmental influences, necessitating a design that can easily provide protection for components within the module.
Innovation Solution
A substrate module with a specific configuration that includes a substrate, power receiving devices, a protected component, and connection components, where the protected component is positioned between the power receiving devices and the connection components, and a protection portion is provided to shield the protected component from external influences like light and heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the thermistor is disposed outside the light emitting device, then it is easier to access and measure temperature, but it becomes vulnerable to external light interference
Solution Approach 1:
The patent introduces a light-shielding member as an intermediary element between the external light source and the thermistor. This mediator blocks harmful light from reaching the thermistor while allowing the thermistor to remain positioned outside the light emitting device for easy temperature measurement and monitoring.
2Reliability
If a protection structure is added to shield components from external factors, then component reliability improves, but module complexity increases
Solution Approach 1:
The light-shielding member is strategically positioned only where needed - specifically to protect the thermistor from external light - rather than providing comprehensive shielding for the entire module. This localized approach protects vulnerable components while minimizing the addition of structural complexity to the overall module design.
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 module effectively protects the target components from external factors, ensuring their operational integrity by positioning the protection portion strategically to cover the protected component without interfering with the power receiving devices, thus maintaining module functionality.
Implementation Method 1
