Plasma Light Enclosure-Holder Structure for Stable Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of output light from a light-emitting sealed body is deteriorated due to reduced convection in the gas space and vibration-induced enclosure vibrations, which are exacerbated by the presence of an enclosure in the housing.
Innovation Solution
A light-emitting sealed body design that includes an insulating enclosure enclosing the plasma region and electrodes, with parts of the enclosure integrated into holders that fix the electrodes to the housing, thereby stabilizing the enclosure and suppressing gas convection and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the enclosure is made separate and movable, then it can be easily assembled, but it vibrates and deteriorates output light quality
Solution Approach 1:
The holder and enclosure are merged into a single integrated structure. The holder that supports the electrode also forms part of the enclosure walls, eliminating the need for a separate enclosure structure. This integration ensures that the enclosure is rigidly supported and cannot vibrate independently, while still maintaining the narrowed gas space for suppressing convection noise.
2Ease of manufacture
If the holder structure is simplified, then manufacturing is easier, but the enclosure becomes unstable and vibrates
Solution Approach 1:
The holder and enclosure are merged into a single integrated structure. The holder that supports the electrode also forms part of the enclosure walls, eliminating the need for a separate enclosure structure. This integration ensures that the enclosure is rigidly supported and cannot vibrate independently, while still maintaining the narrowed gas space for suppressing convection noise.
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 design improves the quality of output light by stabilizing the plasma generation and reducing convection and vibration effects, ensuring stable and high-quality light emission.
Implementation Method 1
a voltage is applied between the pair of electrodes, and thus, arc discharge occurs in the gas in the enclosed space. As a result, the plasma is generated in the enclosed space
Implementation Method 2
a housing that houses a gas for generating plasma, an enclosure that defines an enclosed space including a plasma region in the housing
Implementation Method 3
a laser beam incidence window for causing a laser beam for maintaining the plasma to be incident on the plasma region

AI summary
A light-emitting sealed body includes a housing including a first window configured to cause first light for maintaining the plasma to be incident on the plasma region and a second window configured to cause second light emitted from the plasma to be emitted from the plasma region, a first electrode having a first distal end facing the plasma region, a second electrode having a second distal end facing the plasma region, the second distal end facing the first distal end with the plasma region interposed therebetween, an insulating first holder holding the first electrode and fixed to the housing, and an insulating enclosure enclosing the plasma region, the first distal end, and the second distal end and having a first opening corresponding to the first window and a second opening corresponding to the second window. At least a part of the enclosure is provided to the first holder.
