Solution Overview

Problem

Existing user interfaces for controlling solid-state lighting devices are often complex and difficult for users to navigate, leading to overwhelming color selection charts that result in precise color selection challenges and excessive wireless data traffic, causing system crashes and visual disturbances.

Innovation Solution

A control device with a user-friendly graphical user interface that allows for precise control over light output characteristics such as intensity, correlated color temperature, and color, using adjustment modes like Planck and true color adjustment, with features like scrollable wheels and sliders that reduce data traffic and sporadic changes in lighting output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional color selection charts are used to control solid-state lighting devices, then users can access a wide range of color options, but the interface becomes overwhelming and difficult to navigate

Engineering Contradiction:
Improvecolor selection rangeVSAvoidinterface navigation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent divides the color selection interface into multiple adjustment modes (Planck color mode and true color mode) with separate control features for different parameters (intensity, CCT, color). This segmentation allows users to access comprehensive color control capabilities while navigating through organized, manageable sections rather than an overwhelming single interface.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If precise color control is implemented through detailed adjustment options, then lighting output can be accurately controlled, but wireless data traffic increases causing system crashes

Engineering Contradiction:
Improvecolor control precisionVSAvoidsystem stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent implements dynamic adjustment where control features are enabled or disabled based on the selected adjustment mode. In Planck color mode, only intensity and CCT adjustments are available, while true color mode enables additional color control. This dynamic approach provides precise control when needed while reducing data traffic in simpler modes, preventing system crashes.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple adjustment modes are provided for comprehensive lighting control, then lighting versatility is improved, but device complexity increases

Engineering Contradiction:
Improvelighting control versatilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The user interface dynamically changes based on the selected adjustment mode. When Planck color mode is selected, the interface displays only intensity and CCT control features. When true color mode is selected, additional color control features appear. This dynamic adaptation provides comprehensive lighting control versatility while keeping the interface simple and manageable at any given moment.

Inventive Principle:
Principle #15Dynamics

AI summary

A control device and related user interfaces (UIs) and techniques for controlling the light output of a solid-state lighting device are disclosed. In accordance with some embodiments, the control device may be configured to present a UI having one or more adjustment features operatively associated with one or more adjustment modes by which the control device may control the light output of a downstream lighting device communicatively coupled with the control device. Via a given adjustment feature, a user (or other controller) may adjust one or more characteristics, such as intensity, correlated color temperature (CCT), and color of the emissions of the lighting device. In some embodiments, the control device may be a computing device, mobile or otherwise, and the UI may be presented by a display element as a graphical UI (GUI).
