Solution Overview

Problem

Existing lighting systems using colored lights can make users uncomfortable by illuminating them directly with colored light, which affects their experience and preference.

Innovation Solution

A method and system for controlling a plurality of color light sources that determine a user's position and adjust light settings dynamically, using desaturated light for light sources illuminating the user and saturated light for others, based on a reference light scene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If colored light sources are used to create vibrant ambient lighting and immersive entertainment scenes, then the lighting versatility and entertainment experience are improved, but user comfort deteriorates when users are directly illuminated by colored light

Engineering Contradiction:

Improvelighting versatilityVSAvoiduser comfort

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by differentiating light output based on spatial location relative to the user. Light sources are divided into two groups: those illuminating the user (desaturated/white light) and those providing ambient illumination (saturated/colorful light). This spatial differentiation allows the system to maintain both user comfort and entertainment atmosphere simultaneously.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the light sources into distinct functional groups based on their illumination target. By separating light sources that should illuminate the user from those that should create ambient atmosphere, the system can independently control each group's color temperature and saturation properties, resolving the contradiction between versatility and comfort.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the number of color light sources is increased to enhance entertainment experience, then the lighting scene versatility is improved, but the complexity of controlling and managing these light sources increases

Engineering Contradiction:

Improvelight scene versatilityVSAvoidcontrol complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universality by creating a single control mechanism that handles multiple light sources through a unified classification system. Rather than managing each light source individually, the system uses a general rule set (based on user position and light source orientation) that automatically assigns appropriate color temperature and saturation characteristics to any light source in the array.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method for controlling a plurality of color light sources is provided. The method comprises receiving (2010) a reference light scene comprising a color setting for at least one of the light sources. The method further comprises determining (2020) a position of a user in relation to the plurality of color light sources. The method further comprises determining (2030) a subset of the plurality of color light sources which are arranged to illuminate the position of the user. The method further comprises determining (2040) a desaturated light setting for at least one of the color light sources of the determined subset; and controlling (2050) the plurality of color light sources based on the reference light scene, wherein the at least one color light source of the determined subset is controlled according to the determined desaturated light setting.
