Solution Overview

Problem

Current light bulb technologies are limited by their single RGB color change capability, which cannot simulate the richness and realism of natural light in various scenes, and they lack dynamic adjustment to suit different environmental atmospheres.

Innovation Solution

A method and terminal for controlling intelligent layered multi-scene atmosphere lighting, which automatically acquires scene parameters, extracts characteristic color values from tested picture data, and calculates color values for each lamp bead layer to display dynamic, cyclic color changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If single RGB color change is used in light bulbs, then device complexity is reduced, but color richness and scene realism are insufficient

Engineering Contradiction:
Improvelighting system complexityVSAvoidcolor change capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The lighting system is divided into multiple layers with different lamp beads (warm white, cool white, red, green, blue, yellow) arranged in specific patterns. Each layer contributes different color components, and their combined effect creates rich color variations that simulate natural light spectra, resolving the contradiction between simple device structure and color richness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines multiple types of lamp beads (different colors and temperatures) in a composite lighting module. This composite structure allows the system to generate a wide spectrum of colors by controlling the intensity of each lamp bead type, achieving color versatility without requiring overly complex individual components.

Inventive Principle:
Principle #40Composite materials

2Device complexity

If fixed scene lighting is used, then device complexity is reduced, but dynamic atmosphere adjustment capability is lost

Engineering Contradiction:
Improvecontrol system complexityVSAvoidscene adaptation capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The lighting system transitions from fixed scene lighting to dynamic adjustable lighting. Multiple lamp beads of different colors can be independently controlled to create various lighting effects for different scenes (reading, sleeping, party, etc.). The controller adjusts the intensity and color combination dynamically based on selected scenes, providing adaptability without excessive complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes lighting parameters (color temperature, brightness, color hue) dynamically by adjusting the driving current to different lamp bead types. This allows the same physical hardware to adapt to multiple scenes by simply changing electrical parameters, maintaining device simplicity while achieving high versatility.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If single color lighting is used, then manufacturing precision requirements are reduced, but scene simulation faithfulness deteriorates

Engineering Contradiction:
Improvecolor control precisionVSAvoidscene simulation accuracy
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

Instead of requiring high precision control of a single color source, the patent segments the lighting into multiple color components (warm white, cool white, RGB, yellow). Each component has relaxed precision requirements individually, but their combined output achieves high scene simulation accuracy through additive color mixing and controlled intensity ratios.

Inventive Principle:
Principle #1Segmentation
