Light Source Device Dual Power Supply Voltage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source devices for measurement apparatuses consume high power due to the same voltage being supplied to both light-emitting sections and setters, leading to inefficiencies and potential erroneous operations.
Innovation Solution
A light source device with separate power sources for light-emitting sections and setters, where a first power source supplies a higher voltage to the light-emitting sections and a second power source, with a lower voltage, is used to control the setters, optimizing power distribution and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same voltage is supplied to both light-emitting sections and setters, then the device structure is simple, but power consumption increases and operational stability decreases
Solution Approach 1:
The power source is segmented into a first power source for light-emitting sections and a second power source for setters. This segmentation allows each component to receive appropriate voltage levels, reducing overall power consumption while maintaining operational stability.
Solution Approach 2:
Different voltage levels are applied to different parts of the device: higher voltage to light-emitting sections and lower voltage to setters. This local quality approach optimizes power distribution according to the specific requirements of each component, reducing unnecessary power consumption.
2Device complexity
If the same voltage is supplied to both light-emitting sections and setters, then the device structure is simple, but operational stability decreases
Solution Approach 1:
The power source is segmented into separate first and second power sources, allowing independent voltage optimization for light-emitting sections and setters. This improves operational stability by preventing erroneous operations while maintaining clear structural organization.
Solution Approach 2:
Different voltage levels are applied locally to different components: higher voltage to light-emitting sections for proper operation, and lower voltage to setters for stable control. This local differentiation enhances overall system reliability.
3Illumination intensity
If higher voltage is supplied to light-emitting sections, then light emission performance is improved, but power consumption increases
Solution Approach 1:
Higher voltage is applied only to light-emitting sections where it is needed for optimal light emission, while setters receive lower voltage. This localized voltage distribution maintains light emission performance while reducing overall power consumption.
Solution Approach 2:
The power distribution is segmented into separate first and second power sources, allowing the first power source to provide higher voltage for light emission while the second power source provides lower voltage for control, optimizing the balance between performance and power consumption.
