Solution Overview
Problem
The convection in the gas within a light-emitting sealed body is suppressed, leading to a decrease in the quality of output light, which hinders the performance of devices using the light source.
Innovation Solution
A light-emitting sealed body with a housing that includes a first and second window, and an enclosure defining an enclosed space with narrowed openings, positioned on opposite sides of the enclosed space, to minimize convection and environmental influence on the gas, using insulating materials to stabilize plasma generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an enclosure is disposed in the housing to narrow the convection space, then convection in the gas is suppressed and noise is reduced, but the quality of output light cannot be further improved
Solution Approach 1:
The patent divides the housing into multiple enclosed spaces using partitions. Each enclosed space contains a specific functional component (plasma generation region, light emission region, control circuitry), isolating them from each other to prevent convective interference while maintaining各自的功能性能。This segmentation allows suppression of gas convection without compromising output light quality.
Solution Approach 2:
The patent introduces an enclosure as an intermediary structure between the gas-filled plasma region and the external environment. This enclosure acts as a mediator that suppresses convective flows while allowing controlled light transmission through windows, thereby improving output light quality without directly modifying the plasma generation process.
2Reliability
If both the first opening and the second opening are not narrowed, then the gas is more influenced by the environment outside the housing, but convection occurs more readily
Solution Approach 1:
The patent applies different opening configurations to different regions of the enclosure. The first opening (for plasma region) and second opening (for light emission) have different narrowing degrees optimized for their specific functions. This local differentiation allows the plasma region to be protected from environmental influence while maintaining stable plasma conditions through controlled gas flow.
Solution Approach 2:
The patent transitions from a single-chamber design to a multi-dimensional enclosed structure with multiple openings at different positions and orientations. By narrowing openings in specific dimensions while maintaining others, the patent achieves both environmental isolation and convection control, stabilizing plasma without excessive environmental influence.
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 quality of output light is improved by suppressing convection and environmental influence, ensuring stable plasma maintenance and reducing contamination, while maintaining high accuracy and efficiency of light emission.
Implementation Method 1
a housing that houses a gas for generating plasma, the housing including a first window configured to cause first light for maintaining the plasma in a plasma region where the plasma is generated
Implementation Method 2
a gas for generating plasma
Implementation Method 3
a first window configured to cause first light for maintaining the plasma in a plasma region
Implementation Method 4
a second window configured to emit second light emitted from the plasma from the plasma region
Implementation Method 5
the enclosure is made of an insulating material
Implementation Method 6
since the space where the gas convects is narrowed as compared with a case where the enclosure is not disposed in the housing, it is possible to suppress the occurrence of the convection in the gas

AI summary
A light-emitting sealed body includes a housing including a first window configured to cause first light to be incident on the plasma region, and a second window configured to cause second light to be emitted from the plasma region, and an enclosure defining an enclosed space including the plasma region and having a first opening corresponding to the first window and a second opening corresponding to the second window. The first window is positioned on an opposite side to the enclosed space with respect to an open end of the first opening on the enclosed space side, and the second window is positioned on an opposite side to the enclosed space with respect to an open end of the second opening on the enclosed space side. At least one of the first opening and the second opening is narrowed with respect to the enclosed space.
