Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid-cooled LED tower lamps are cumbersome to maintain or replace, as they often require drainage of coolant and are specific to particular types, leading to time-consuming and costly replacements, and their design limits power output due to inefficient use of LEDs at certain Correlated Color Temperature (CCT) settings.
Innovation Solution
A modular lighting assembly with a chassis and interface that allows fluid to pass through the LED assembly during installation and prevents leakage when removed, along with a controller that determines the type of LED assembly and optimizes light emission, enabling efficient coolant management and enhanced power output by utilizing additive lighting techniques across multiple CCT channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid-cooled LED tower lamps are integrated with housing components, then cooling efficiency is improved, but maintenance and replacement become cumbersome and time-consuming
Solution Approach 1:
The lighting system is divided into separate modular components: the LED tower lamp and the housing components. The LED tower lamp includes an integrated cooling system that can be removed as a single unit from the housing, allowing maintenance and replacement without draining coolant or replacing the entire assembly. This segmentation resolves the contradiction by maintaining integrated cooling efficiency while enabling easy maintenance through component separation.
2Temperature
If housing components are specific to particular types of LED tower lamps, then cooling performance is optimized, but adaptability and versatility are reduced
Solution Approach 1:
The housing components are designed with universal mounting interfaces and fluid pathways that can accommodate different types of LED tower lamps. The housing includes a mounting interface that receives various LED tower lamp configurations, and fluid pathways that can be configured to match different cooling requirements. This universality allows a single housing design to support multiple LED tower lamp types while maintaining optimized cooling performance through adaptable fluid pathway configuration.
3Illumination intensity
If LEDs are used at extreme CCT settings, then color temperature control is achieved, but power output is limited due to inefficient LED utilization
Solution Approach 1:
The LED driver circuitry dynamically adjusts the operation of LED channels based on the desired CCT setting. At extreme CCT settings (e.g., 2700K or 6504K), the driver activates only the necessary LED channels to achieve the target color temperature, optimizing power efficiency. The system transitions between different LED channel configurations dynamically, ensuring maximum power output at each CCT setting by activating the most efficient LED combinations rather than operating all LEDs at full power regardless of CCT requirements.

AI summary
A lighting assembly includes a chassis and an interface. The interface is configured to allow fluid to pass through the chassis to a light emitting diode (LED) assembly when the LED assembly is installed at the interface. Additionally, the interface is configured to prevent the fluid from exiting the chassis when the LED assembly is not installed at the interface.
