Multi-Color LED Light Fixture with Switchable Color Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light fixtures, particularly those with LED lights, often lack versatility in color options, making it difficult for contractors to meet varying lighting needs and for consumers to change the light color after installation.
Innovation Solution
A light fixture with multiple colored LED light sources and a switch that allows users to choose between powering individual colors or blending them to create a third color, providing options for different lighting modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light fixture uses a single colored LED light source, then the device complexity is reduced, but the adaptability or versatility is limited
Solution Approach 1:
The light fixture is segmented into multiple independent LED light sources, each emitting a different color (e.g., warm white 3000K and cool white 5000K). Each color channel can be independently controlled through separate circuit connections to a common power source, allowing selective activation of individual color groups without increasing overall structural complexity
Solution Approach 2:
The light fixture incorporates multiple LED light sources with different color temperatures within a single device, enabling it to perform multiple lighting functions (warm lighting, cool lighting, and blended neutral lighting) from one universal fixture installation
2Adaptability or versatility
If a light fixture provides multiple colored LED light sources, then the adaptability or versatility is improved, but the device complexity increases
Solution Approach 1:
The light fixture incorporates a switchable control mechanism that allows dynamic selection between different lighting modes (single color or blended color). The switch can be positioned to select between warm white only, cool white only, or a blended combination of both colors, providing adaptability without requiring complex electronic controls
Solution Approach 2:
The patent merges multiple LED light sources of different colors into a single integrated fixture with a unified power connection and simple switch control. The control mechanism combines selection of individual color channels and blended modes into one straightforward switching system, reducing operational complexity despite multiple light sources
3Ease of operation
If contractors install light fixtures with specific colors, then the lighting needs are met, but the ability to change light color after installation is limited
Solution Approach 1:
The light fixture is pre-configured during manufacturing with multiple LED light sources of different color temperatures and the associated control switching mechanism. This preliminary setup allows the fixture to be installed once and then easily reconfigured between different color modes (warm white, cool white, or blended) through simple switch positioning, eliminating the need for reinstallation to change colors
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily select and adjust the light color to meet specific lighting conditions, enhancing flexibility and user satisfaction by allowing operation in single color or blended modes.
Implementation Method 1
a plurality of two or more different colored LED (Light emitting Diode) light sources
Implementation Method 2
the user can operate the light fixture in three modes, with the first color only, the second color only, or both the first and the second color to obtain a blended color
