Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stage light fixtures often suffer from inadequate cooling, leading to overheating and potential damage due to insufficient or excessive cooling, which reduces the lifespan of the light source and can result in breakage.
Innovation Solution
A stage light fixture with a regulated cooling assembly monitored by a monitoring assembly that adjusts the cooling based on operative conditions, ensuring optimal internal casing cooling through controlled fan speed and voltage adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling device is added to remove heat from the casing, then the temperature inside the casing is reduced, but the cooling may be insufficient or excessive leading to overheating or light source breakage
Solution Approach 1:
The patent applies dynamics by making the cooling system adjustable through multiple fan speed levels (low, medium, high) controlled by a control unit. This allows the cooling intensity to be dynamically adapted to different operating conditions, preventing both overheating and excessive cooling that could damage the light source.
Solution Approach 2:
The patent implements feedback through temperature sensors that continuously monitor the internal temperature of the casing and provide information to the control unit. The control unit adjusts fan speeds based on this temperature feedback, creating a closed-loop control system that maintains optimal temperature and prevents light source damage.
2Temperature
If a cooling device is installed in the casing, then heat removal capability is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the cooling system into modular components: multiple independent fans (first fan, second fan), separate temperature sensors for different locations, and a control unit that manages each component independently. This modular approach allows for targeted cooling zones and simplifies maintenance while improving heat removal capability.
