Lamp Bracket With Inductive Sensor For UV Lamp Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UV fluorescent lamps pose a risk to human health due to ultraviolet radiation, as they can be accidentally left on in occupied spaces, causing eye and skin damage, and existing solutions do not adequately address the safety concern of ensuring the lamps are turned off when people are present.
Innovation Solution
A lamp bracket system that includes inductive components, such as IR and microwave sensors, to detect the presence of humans and automatically turn off the UV fluorescent tube, integrated with a backboard and lamp base components to form a containing groove for the tube, ensuring safe operation by controlling power supply based on occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UV fluorescent lamp is installed for sterilization and disinfection, then sterilization effect is improved, but safety risk increases due to potential accidental exposure to ultraviolet radiation
Solution Approach 1:
The patent applies feedback control by using inductive components (sensors) to detect human presence and automatically controlling the UV lamp state. When the sensor detects a human body, it sends a signal to turn off the UV lamp, creating a closed-loop safety mechanism that prevents accidental exposure while maintaining sterilization effectiveness when the space is unoccupied
Solution Approach 2:
The patent introduces an intermediary control system between the power supply and the UV lamp. This intermediary includes inductive components that detect human presence and a control circuit that mediates the power delivery, automatically interrupting power supply when humans are detected and thus preventing direct harmful exposure while preserving the sterilization function
2Device complexity
If manual control of UV fluorescent lamp is used, then device complexity is reduced, but safety control capability deteriorates due to reliance on user awareness
Solution Approach 1:
The patent implements self-service safety control by enabling the system to automatically monitor and control itself. The inductive components continuously detect human presence and the control circuit automatically adjusts the lamp state without requiring user intervention, making the safety function autonomous and eliminating reliance on user awareness while adding only moderate complexity
Solution Approach 2:
The patent replaces manual mechanical control with automated sensing and control systems. Instead of relying on manual switches and user awareness, the system uses inductive components (sensors) to detect human presence and electronically controls the power supply, substituting mechanical/user-based control with automated sensing-based control to improve safety
