LED Candle Flame Element with Magnetic Swing and Segmented Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial LED candles lack a realistic simulation of a burning candle flame, particularly in terms of the swinging motion and color gradation of a real candle flame, as most use fixed light bulbs or lamp shades that do not accurately depict the dynamic and multi-tonal nature of a burning candle.
Innovation Solution
An artificial LED candle design featuring a flame element with a magnetic component and a coil system that allows the flame to swing, combined with multiple LED light sources to simulate the center and side parts of a real candle flame, providing a more realistic color representation by illuminating the flame element with distinct light shades to mimic the appearance of a real candle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed light bulbs or lamp shades are used to cover the LED light sources, then the structure is simple and easy to manufacture, but the flame cannot swing and the simulation effect is poor
Solution Approach 1:
The flame element is designed with a magnetic component that interacts with a coil system to enable dynamic swinging motion, transforming the static flame structure into a dynamic one that simulates the natural movement of a real candle flame
Solution Approach 2:
The flame element is divided into multiple sections with different light-transmitting properties (middle section with first light-transmitting property, side sections with second light-transmitting property), allowing independent control and illumination of different parts to achieve realistic color gradation
2Reliability
If monotonous light shades are used in artificial LED candles, then the manufacturing process is simple, but the simulation effect is poor because real candle flames have different shades in different parts
Solution Approach 1:
Different sections of the flame element are assigned different light-transmitting properties and are illuminated by separate LED light sources with different colors, creating local variations in color and brightness that match the natural gradation of a real candle flame
Solution Approach 2:
The patent employs multiple LED light sources emitting different colors (e.g., yellow for the middle section, orange/red for side sections) to illuminate corresponding parts of the flame element, achieving realistic color gradation that mimics the appearance of a real burning candle
3Reliability
If a single LED light source is used, then the device complexity is low, but the flame simulation lacks the color variation present in real candle flames
Solution Approach 1:
The illumination system is segmented into multiple independent LED light sources, each responsible for illuminating a specific section of the flame element, allowing independent control of color and intensity for each region to achieve realistic flame appearance
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
The solution achieves a more realistic simulation of a burning candle flame by allowing the flame to swing and accurately depicting the color gradation of a real candle, enhancing the aesthetic appeal and authenticity of the artificial LED candle.
Implementation Method 1
the circuit board controls a power supply to the coil, the magnetic element is pushed or pulled (suffered a Lorentz force when the magnetic element is a magnet, or a magnetic force when the magnetic element is an iron) accordingly so as to swing the flame element
Implementation Method 2
a first LED light source, a second LED light source... The LED light sources arranged in the housing illuminate the flame element to illuminate a real candle flame with different light shadow

AI summary
An artificial LED candle includes a flame element with an upper section with a flame silhouette outlook, at least one first LED light source used for illuminating a center part of the upper section of the flame element, and at least one second LED light source used for illuminating one or two side parts of the upper section of the flame element. The center part of the upper section is illuminated by both the first and the second LED light sources, while the two side parts of the upper section is illuminated only by the second LED light source. Therefore, a center part is brighter than the two side parts of the upper section of the flame element, just like a real burning candle flame. Color simulation and light shadow presented on the flame element is more realistic, a simulate effect is improved.
