Color-Adjustable Lighting Control for Object Color Emphasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling color adjustable light sources, such as RGB LEDs, are complex and difficult for non-experts to use effectively, making it challenging to achieve optimal illumination that highlights a specific color of an object, especially in settings like stores or museums.
Innovation Solution
A method and system that set a color temperature of a reference white point adjacent to the black body curve, acquire information about the object's color, and adjust the light source's saturation level using the CIE 1931 x, y color space to illuminate the object with light between the reference point and the object's color point, ensuring the object's color is highlighted and made more visible.

1Ease of operation
If conventional control methods with multiple parameters (hue, saturation, brightness) are used, then the light source can be adjusted to highlight object colors, but the control becomes complicated and requires expert knowledge and multiple adjustment attempts
Solution Approach 1:
The invention extracts and isolates the saturation parameter from the complex multi-parameter control system. By focusing solely on saturation adjustment while maintaining fixed hue and brightness, the system simplifies user interaction to a single intuitive control dimension, eliminating the need for experts to coordinate multiple interdependent parameters
Solution Approach 2:
The invention changes the control parameter from the traditional three-dimensional HSV space (hue, saturation, brightness) to a simplified one-dimensional saturation adjustment along a fixed hue-brightness trajectory. This parameter reduction transforms a complex multi-parameter optimization problem into a simple single-parameter adjustment, making the system accessible to non-experts
2Manufacturing precision
If multiple parameters are adjusted to achieve optimal color highlighting, then the illumination can be optimized, but the process becomes time-consuming and requires several adjustment attempts
Solution Approach 1:
The system performs preliminary action by pre-establishing the optimal hue and brightness settings before the user interaction. The control method fixes the hue angle and brightness level in advance, so that when the user adjusts saturation, the system immediately produces optimal color highlighting without requiring iterative adjustments of multiple parameters
Solution Approach 2:
The invention segments the control process into independent stages: system initialization sets the fixed hue and brightness parameters, while user interaction only controls saturation. This segmentation separates the complex optimization tasks (performed automatically during initialization) from the simple user-controlled adjustment, reducing overall adjustment time

AI summary
A method for controlling a color adjustable light source (101) configured to illuminate an object (110) is disclosed. The method comprises the steps of setting (301) a color temperature of a reference white point (cpref) at the black body curve (202), acquiring (302) information as to a color of the object (cpobj), receiving (303) a desired saturation level, and controlling (304) the light source (101) to illuminate the object (110) with light corresponding to the color temperature of the reference white point and comprising a saturated component corresponding to the color of the object. A corresponding system (100) for performing the method is also disclosed.
