Sanitary Lighting Control via Luminous Flux and Color Curves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems for sanitary rooms, such as bathrooms, fail to provide optimal lighting adjustments that cater to various activities and user preferences, particularly in smaller spaces, as they primarily control brightness without considering color temperature changes, leading to inadequate lighting for orientation, mood, standard, and work tasks.
Innovation Solution
A method for controlling sanitary room lighting that uses a user-adjustable actuator to modify both luminous flux and light color based on predefined functional curves, allowing continuous transitions between different lighting situations, ensuring optimized lighting for various activities by adjusting luminous flux and color temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only luminous flux (brightness) is controlled without color temperature changes, then the control system remains simple, but the lighting quality is insufficient for various activities and user preferences
Solution Approach 1:
The patent applies parameter changes by simultaneously controlling two light parameters: luminous flux (brightness) and color temperature. The control system uses function curves to define the relationship between a single control value and these two parameters, enabling dynamic adjustment of lighting quality for different activities (orientation, mood, standard, work lighting) without requiring multiple independent controls.
2Adaptability or versatility
If multiple discrete lighting situations are provided, then specific lighting needs are met, but the user interface becomes complex and requires multiple selections
Solution Approach 1:
The patent implements universality by using a single control element (actuator) that provides multi-functionality. This single control simultaneously adjusts both luminous flux and color temperature according to predetermined function curves, enabling the user to access multiple lighting situations (orientation, mood, standard, work lighting) through one unified interface rather than multiple discrete controls.
Solution Approach 2:
The patent applies dynamics by enabling continuous adjustment of lighting parameters through a single control value. Instead of discrete preset modes, the system dynamically transitions between different lighting situations as the control value changes, providing smooth transitions and flexible adaptation to user needs while maintaining a simple user interface.
3Adaptability or versatility
If lighting is optimized for specific activities, then lighting quality improves, but the system requires complex configuration for each setting
Solution Approach 1:
The patent applies preliminary action by pre-defining function curves that establish the relationship between control values and lighting parameters (luminous flux and color temperature). These function curves are stored in the control system and automatically applied when the user adjusts the actuator, eliminating the need for complex real-time configuration while still providing optimized lighting for various activities.
