Waterproof Light Head Modular Cavity Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof light head structures for stage lights are inconvenient to mount and maintain, and they cannot easily switch between waterproof and non-waterproof modes, limiting their versatility in various applications.
Innovation Solution
A waterproof light head structure featuring a main bracket with a front cover and rear cover that form a cavity, connected to upper and bottom plates for sealed connections, allowing for easy assembly and disassembly, and enabling conversion between waterproof and non-waterproof modes by removing the front and rear covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light head is designed as a complete sealed waterproof structure, then waterproof performance is improved, but mounting and maintenance convenience deteriorates
Solution Approach 1:
The light head is divided into separate modular components: a main body containing optical components, a separate waterproof housing, and interchangeable front/rear covers. This segmentation allows the waterproof housing to be assembled and disassembled independently for maintenance while maintaining waterproof integrity when assembled, resolving the contradiction between sealed structure and maintenance convenience.
2Reliability
If the side plates of the light head bracket are used as housing parts to achieve waterproofing, then waterproof performance is improved, but structural complexity and maintenance difficulty increase
Solution Approach 1:
The waterproof housing is extracted as a separate functional module from the bracket structure. Instead of integrating waterproofing into the bracket's side plates, a dedicated waterproof housing with sealed covers is used, simplifying the bracket's role to support and positioning while the housing handles all waterproof functions, reducing overall structural complexity.
3Reliability
If the light head is designed as a fixed waterproof structure, then waterproof performance is improved, but adaptability to different applications deteriorates
Solution Approach 1:
The light head design incorporates dynamic configurability through interchangeable front and rear covers that can be attached or removed based on application requirements. The modular architecture allows the same base unit to be adapted for waterproof outdoor use or non-waterproof indoor use, providing versatility while maintaining waterproof performance when needed.

AI summary
A waterproof light head structure includes a main bracket, a front cover and a rear cover respectively arranged on the front side and the rear side of the main bracket, an upper plate arranged above the main bracket, a bottom plate arranged below the main bracket, a lens assembly arranged on the main bracket via the upper plate, and a light source arranged in the main bracket. The main bracket is arranged in a cavity formed by joining the front cover and the rear cover. The front cover and the rear cover are respectively in sealed connection with the upper plate and the bottom plate, and the side edges where the front cover and the rear cover are joined are in sealed connection to form an all-around waterproof structure. The waterproof light head according to the present invention is simple in structure, while the waterproof performance is guaranteed.
