Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp operating devices lack the ability to effectively influence and extend the service life of lighting systems, as they do not provide users with direct control over temperature regulation, leading to potential overheating and reduced lifespan.
Innovation Solution
An operating device with a control circuit that detects temperature and adjusts parameters such as power or switching frequency to prevent overheating, allowing users to set a critical temperature via manual or data-technical interfaces, and includes a temperature sensor for internal or external temperature measurement, enabling adaptive protection modes to extend or reduce service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operating device operates at high power continuously, then productivity and energy efficiency are improved, but the service life and reliability deteriorate due to overheating
Solution Approach 1:
The operating device incorporates a temperature sensor that continuously monitors the internal temperature and feeds this information back to the control unit. When the temperature reaches a predetermined critical value, the control unit automatically reduces the output power of the converter to prevent overheating and extend service life. This closed-loop feedback mechanism enables the device to adapt its operation based on thermal conditions.
Solution Approach 2:
The invention allows changing the critical temperature parameter through a manual interface (potentiometer) or data technical interface (communication bus). By adjusting this parameter, users can adapt the device's thermal protection threshold to different operating conditions and service life requirements, enabling flexible optimization between productivity and reliability.
2Reliability
If a fixed critical temperature is programmed in the control unit, then temperature protection is improved, but adaptability to different service life requirements deteriorates
Solution Approach 1:
The critical temperature is transformed from a fixed programmed value to a dynamically adjustable parameter. A manual interface with a potentiometer allows direct adjustment of the critical temperature on the device, while a data technical interface enables remote adjustment via communication protocols. This dynamic adjustment capability allows the same device to be adapted to different service life requirements and operating conditions.
Solution Approach 2:
The operating device is designed to serve multiple functions: it can operate with different critical temperature settings to meet various service life requirements, support both manual and remote configuration methods, and provide both temperature protection and adaptability features within a single integrated system.
3Ease of operation
If manual adjustment of critical temperature is provided, then ease of operation is improved, but device complexity increases due to additional interface components
Solution Approach 1:
The manual interface with a potentiometer enables the end user to directly adjust the critical temperature parameter without requiring external programming equipment or technical expertise. The user can simply rotate the potentiometer to set the desired temperature threshold, making the device self-configurable and easy to operate while avoiding the need for complex external programming interfaces.
