Scenographic Light Fixture Waterproof Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scenographic light fixtures cannot be used outdoors due to their inability to meet dust and water protection requirements of current safety regulations, limiting their application in the entertainment industry.
Innovation Solution
A scenographic light fixture with a waterproof chamber supported by a transparent, cup-shaped polymeric material (PMMA or PC) that houses a mobile optical element and electric motors, allowing beam deflection without rotating the main body, and an air cooling system with hermetically sealed inlets and outlets to prevent external agents from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional open structure is used for the light fixture, then the optical elements can be easily accessed and the device is simpler to manufacture, but the fixture cannot be used outdoors due to lack of dust and water protection
Solution Approach 1:
The patent employs a transparent support structure that forms a waterproof chamber, acting as a protective shell around the optical elements. This transparent enclosure provides dust and water protection while maintaining optical functionality, resolving the contradiction between protection and simplicity.
2Reliability
If the main body is rotated to change beam direction, then the structure remains simple without additional components, but the fixture cannot maintain stable positioning in outdoor conditions with wind and weather exposure
Solution Approach 1:
The patent segments the beam direction control function from the main body rotation. A separate control device with mobile optical elements handles beam deflection, while the main body remains stationary and stable. This segmentation allows independent optimization of both stability and orientation flexibility.
Solution Approach 2:
The patent introduces a transparent support as an intermediary structure that holds the mobile optical elements. This intermediary enables beam deflection without requiring rotation of the entire main body, providing stable positioning while maintaining operational flexibility.
3Reliability
If a transparent support is used to house the control device, then dust and water protection is achieved while maintaining optical efficiency, but the manufacturing process becomes more complex
Solution Approach 1:
The patent uses polymeric material for the transparent support structure, combining optical transparency with mechanical strength and waterproof properties. This composite material approach achieves protection against external agents while maintaining ease of manufacturing through molding processes.

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 solution provides a high level of protection against dust and water, enabling outdoor use while maintaining efficiency and offering a range of performance characteristics and interchangeable supports for various scenographic effects.
Implementation Method 1
a support, which is at least in part transparent to the light beam, and is fitted to the main body to support the control device
Implementation Method 2
a control device facing the main body and comprising a mobile optical element to intercept and selectively deflect the light beam in a plurality of directions
Implementation Method 3
The cooling system consists of drawing in air through inlets arranged in the walls, making the air circulate inside the main body, especially in correspondence with the light source, and discharging the hot air through outlets arranged in the walls
