Solution Overview
Problem
Untrained users find it difficult to create an attractive atmosphere by setting harmonious colors in illumination systems, as adjusting light colors to match backgrounds or objects requires trial and error.
Innovation Solution
An illumination system comprising a color-variable luminaire, a color sensor to measure background or object colors, and a controller with memory rules for determining harmonious color settings, allowing automatic adjustment of light colors based on sensed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of light sources with different colors are used to create variable color illumination, then the ability to change light color is improved, but the difficulty for untrained users to set harmonious colors increases
Solution Approach 1:
The system automatically detects background colors using color sensors and applies harmony rules through the controller without requiring user intervention. The illumination device serves itself by autonomously selecting harmonious color combinations based on the detected environment, eliminating the need for untrained users to manually adjust multiple light sources to achieve harmonious colors.
Solution Approach 2:
The system uses color sensors to detect the background color and feeds this information back to the controller. The controller then processes this feedback by applying harmony rules from its memory to determine the optimal color settings for the light sources, creating a closed-loop system that automatically achieves harmonious color matching based on environmental conditions.
2Manufacturing precision
If manual adjustment of light source intensities is required to match background colors, then color matching capability is improved, but the time and effort required for trial and error increases
Solution Approach 1:
The system pre-stores multiple color harmony rules in the controller's memory before operation. When the color sensor detects a background color, the controller quickly retrieves and applies the appropriate pre-defined harmony rule, eliminating the need for time-consuming trial and error adjustments. The harmonious color combinations are prepared in advance and ready for immediate application.
Solution Approach 2:
The controller acts as an intermediary between the color sensor detection and the light source adjustment. It processes the detected background color information, applies harmony rules from memory, and automatically calculates the optimal intensity settings for each light source, replacing manual trial and error with automated intelligent control.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables users to easily match light colors with surroundings or objects, creating a harmonious atmosphere without the need for trial and error, by using a color sensor and controller to apply predefined harmony rules for optimal color selection.
Implementation Method 1

Data Source
AI summary
An illumination system and method is disclosed. In one example, the illumination system comprises a lamp assembly for generating color-variable light, a controller for generating control signals for the lamp assembly, source color input means, preferably a color sensor, for inputting to the controller information defining a source color; a memory associated with the controller, containing information defining at least one color harmony rule. On the basis of the input source color, and using the harmony rule from the memory, the controller calculates a target color and generates its output control signals accordingly. Thus, the light output from the lamp assembly harmoniously matches the measured color of surroundings or objects.
