Solution Overview
Problem
General users find it difficult to adjust the quantity and color temperature of light from a light source while maintaining a balance, especially in varying illumination environments, as existing systems require manual expertise and lack user-friendly interfaces.
Innovation Solution
An illumination controller with a rotatable dial and memory-based control curves that allow users to adjust color temperature and light quantity in conjunction, featuring multiple control curves for different environments and a timer for automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of light quantity and color temperature is implemented, then users can control illumination parameters, but general users without expertise cannot maintain a good balance between quantity and color temperature
Solution Approach 1:
The control curves are pre-calculated and stored in the memory unit, defining the optimal relationship between light quantity and color temperature in advance. When a user selects a curve, the system automatically applies the pre-defined balanced relationship, eliminating the need for users to manually balance these parameters while maintaining expertise-level precision.
2Adaptability or versatility
If manual adjustment interface is provided, then users can set illumination parameters, but general users cannot set parameters according to illumination environment such as location or time zone
Solution Approach 1:
The control method is segmented into distinct operational modes (morning, noon, evening, night) with dedicated control curves for each. This segmentation allows the system to automatically adapt to different illumination environments without requiring users to understand complex parameter relationships, as each mode provides environment-optimized settings.
Solution Approach 2:
The system dynamically selects appropriate control curves based on the current time or selected mode, automatically adjusting the relationship between light quantity and color temperature to match the illumination environment. This dynamic adaptation enables general users to benefit from environment-specific optimization without manual intervention.
3Adaptability or versatility
If multiple control curves are provided for different environments, then users can select appropriate settings, but the device complexity increases
Solution Approach 1:
Multiple control curves are stored as data sets in the memory unit rather than implementing separate physical control circuits for each mode. This copying approach allows multiple control modes to be implemented through software/data storage, significantly reducing hardware complexity while maintaining the ability to provide environment-specific optimization.

AI summary
An illumination controller, which is configured to control a light source unit, includes: a dial, which is rotatable, used to adjust a color temperature and a quantity of light irradiated from the light source unit, a memory which stores one or more control curves in which the color temperature and the quantity of light irradiated from the light source unit change in conjunction with each other; and a curve selection unit used to select one curve among the control curves stored in the memory. When the dial is rotated, the color temperature and the quantity of light irradiated from the light source unit change according to values defined on the control curve selected by the curve selection unit.
