Ceiling Airway Lamp Shield Structure for Dustproof Secure Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling-mounted ventilation fans with illumination suffer from issues where water or dust can enter and cause short circuits, and the lamp may fall due to poor electrical connections during installation.
Innovation Solution
A ceiling-mounted airway device with a cylindrical shield surrounding the electrically conductive contact terminal and lamp fixing part, featuring a flange and elastic tabs to prevent water and dust from reaching live parts and to securely hold the lamp in place, preventing it from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lamp is detachably mounted in the frame, then the lamp can be easily installed and removed, but water or dust can enter the gap between the contact terminal and lamp fixing part causing short circuits
Solution Approach 1:
A waterproof dustproof ring is introduced as an intermediary component between the lamp contact terminal and the lamp fixing part. This ring effectively blocks water and dust from entering the gap, while still allowing the lamp to be detachably mounted for easy installation and removal.
2Ease of operation
If the lamp is detachably mounted in the frame, then the lamp can be easily installed and removed, but the lamp may fall down due to poor connection
Solution Approach 1:
The mounting structure is segmented into distinct functional components: the lamp fixing part with positioning protrusions, the lamp contact terminal with corresponding positioning grooves, and the waterproof dustproof ring. This segmentation allows for easy assembly and disassembly while maintaining stable connection through precise positioning features.
3Illumination intensity
If the reflector length is set to be larger than the lamp length, then the light can be properly reflected into the room, but water or dust can pass through and reach the electrical components
Solution Approach 1:
The waterproof dustproof ring serves as a protective intermediary that blocks water and dust from passing through the reflector area and reaching the electrical components, while maintaining the reflector's optimal length for proper light reflection into the room.

AI summary
A ceiling mounted airway device with illumination, which includes a main housing, a lamp and a lamp fixing part to detachably fix the lamp to an inner wall of the main housing. The main housing includes: a first opening for exhausting air out of the main housing; and a second opening for sucking air into the main housing. The lamp includes: an electrically conductive contact terminal located at an upper end of the lamp and electrically powered via the lamp fixing part; and a flange protruding from a surface of the lamp and located below the electrically conductive contact terminal. The device further includes a shield for supporting the flange which is substantially in form of a cylinder and surrounds the electrically conductive contact terminal and the lamp fixing part.
