Sealed UV Lamp Assembly With Oblique Connector for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultraviolet radiation lamps used in water treatment systems experience vibration-induced disconnection issues due to turbulence, leading to incomplete disinfection and potential contamination during field replacement, as the existing solutions like slant-based lamp assemblies compromise watertight integrity and sanitization performance.
Innovation Solution
A sealed radiation source assembly with a UV transparent sleeve and a source base featuring an obliquely angled electrical connection interface, including a radial sealing element, compression ring, and retaining device, which ensures a secure and reliable electrical connection and watertight seal, even after field replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical connection pins are disposed parallel to the longitudinal axis of the radiation lamp, then the electrical connection structure is simple, but the lamp vibrates loose from its electrical connection base due to turbulence-induced vibration
Solution Approach 1:
The electrical connection pins are disposed at an oblique angle (e.g., 15-45 degrees) relative to the longitudinal axis of the radiation lamp, creating an asymmetric configuration. This oblique arrangement prevents the lamp from vibrating loose during operation while maintaining a relatively simple connection structure.
2Reliability
If a quartz sleeve is installed over the lamp and connector to prevent vibration disengagement, then the lamp connection stability is improved, but field replacement leads to contamination and loss of watertight integrity
Solution Approach 1:
The electrical connection interface is pre-configured with an oblique angle design that inherently prevents vibration disengagement, eliminating the need for additional protective quartz sleeves during field replacement operations. This preliminary design solution addresses the stability issue without introducing contamination risks.
3Productivity
If the radiation lamp is immersed in flowing water, then the water treatment function is effective, but turbulence creates vibratory motion that causes lamp disconnection
Solution Approach 1:
The oblique angle configuration of the electrical connection pins creates an asymmetric geometry that resists the vibratory forces generated by turbulent water flow, allowing the lamp to remain securely connected while maintaining effective water treatment functionality.

AI summary
A radiation source assembly comprises a source base, a UV transparent sleeve, and a UV lamp. The source base comprises a sealed electrical connection interface and an opposing sealed sleeve interface. The sealed electrical connection interface comprises a electrical contacts and the sealed sleeve interface comprise a radial sealing element, an outer collar, and a compression ring. The UV transparent sleeve is engaged with the sleeve interface such that the radial sealing element of the sealed sleeve interface is disposed between the UV transparent sleeve and the outer collar of the source base, and the compression ring is positioned over the UV transparent sleeve and engaged with the source base to compress the radial sealing element onto the UV transparent sleeve and the outer collar. The UV lamp is disposed within the UV transparent sleeve and electrically coupled to the electrical contacts of the electrical connection interface.
