Illumination Device Adaptive Color Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illuminating devices face challenges in precisely adjusting the color of emitted light to match the color of objects due to the vast range of possible colors, leading to poor preciseness in self-adaptive color adjustment.
Innovation Solution
The control method and system for the illuminating device project initial and target detection lights, acquire chromaticity coordinate values, and adjust the light using a preset weighting coefficient to determine the target color, ensuring the color difference is within a preset range, allowing continuous coordination with the object's color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single irradiating light is used for each color zone in the irradiating light list, then the device complexity is reduced, but the manufacturing precision of color coordination deteriorates
Solution Approach 1:
The patent segments the color adjustment process into multiple iterative detection cycles. Instead of using a single irradiating light for each color zone, the system divides the adjustment into multiple steps where detection light is projected, reflected light color is acquired, target color is calculated, and color difference is evaluated. This segmentation allows for progressive refinement of color coordination precision while maintaining manageable device complexity.
Solution Approach 2:
The patent implements a dynamic iterative adjustment mechanism where the illuminating device continuously adapts its irradiating light color based on real-time feedback from reflected light detection. The system dynamically updates the target color through multiple cycles of detection and adjustment, allowing the color coordination to evolve and improve progressively rather than relying on a static single-light approach.
2Manufacturing precision
If multiple detection cycles with iterative color adjustment are implemented, then the color coordination precision is improved, but the loss of time increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing the irradiating light list with multiple color zones and pre-defining the detection protocol before actual color adjustment begins. The system prepares the framework for iterative adjustment in advance, including the chromaticity coordinate calculation method and color difference evaluation criteria, so that the actual detection and adjustment process can proceed efficiently without ad-hoc decision-making delays.
Solution Approach 2:
The patent implements a feedback mechanism where the color difference between initial and target reflected light is continuously evaluated against a preset range. This feedback loop allows the system to determine when color coordination has been achieved and stop the iterative process, preventing unnecessary time consumption while ensuring sufficient precision. The feedback criterion (color difference within preset range) provides an objective stopping condition for the detection cycles.

AI summary
Embodiments of the present invention disclose an illuminating device, a control method thereof and a control system thereof, which can precisely adjust the color of irradiating light according to the color of an object. In the embodiment of the present invention, a next detection light is obtained according to reflected light of a previous detection light. When the color difference of reflected light of the previous detection light and the next detection light is less than a preset color difference range, the illuminating device is controlled to project the next detection light to an illuminated object. No matter how the color of the illuminated object changes, or even the color change is very subtle, a detection light of which the color is mostly coordinated with the illuminated object can also be automatically obtained to illuminate the object continuously.
