Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current artificial candle and flame-effect products lack realism in simulating a 3D flame effect, as they primarily rely on diffusion methods or mechanical movements, failing to replicate the depth and movement of actual flames from different angles.
Innovation Solution
Incorporating a novel arrangement of multiple lenticular lenses with unique orientations in a non-flat configuration combined with an array of RGB LEDs and a sequential LED algorithm to simulate the movement and color changes of a flame, creating a realistic 3D flame effect across 360 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If diffusion methods or mechanical movements are used to simulate flame, then the device structure is simple, but the 3D flame effect and realism are insufficient
Solution Approach 1:
The device segments the light source into multiple individual LEDs arranged in a specific pattern, allowing independent control of each LED to create different flame states. The lenticular lens is also segmented into multiple lens elements, each contributing to different viewing angles and depth perception, thereby enhancing flame realism through divided functional elements.
Solution Approach 2:
The patent transitions from 2D flame simulation to 3D flame effect by introducing a lenticular lens array that creates parallax and depth perception. Multiple LEDs positioned at different spatial coordinates emit light that refracts through the lenticular lenses, producing a three-dimensional flame appearance that changes dynamically with viewing angle, adding a crucial dimensional aspect to the simulation.
2Device complexity
If multiple LEDs are arranged in a circular pattern with a single layer diffuser, then the device complexity is reduced, but the 3D appearance and depth effect are lost
Solution Approach 1:
The patent employs a nested lens structure where a first lenticular lens is positioned within or integrated with a second lenticular lens, creating multiple layers of light refraction. This nested arrangement of optical elements enhances the 3D effect by processing light through successive lens layers, each contributing to depth perception and angular variation, while maintaining a compact integrated design.
Solution Approach 2:
The multi-layer lenticular lens configuration adds optical depth and spatial dimension to the flame simulation. By stacking or nesting lens layers with different orientations or focal properties, the system creates complex light paths that produce genuine 3D visual effects, transforming a potentially flat 2D LED display into a volumetric flame appearance.
3Illumination intensity
If a lenticular lens is used to create depth illusion, then the 3D effect is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The lenticular lens array serves multiple functions simultaneously: it creates depth perception, controls light distribution across different viewing angles, and defines the spatial position of virtual flame elements. This multi-functionality consolidates several optical requirements into a single component system, reducing the need for separate optical elements and simplifying the overall manufacturing process despite the advanced optical effects achieved.

AI summary
Apparatus and method for creating a natural flame effect using an RGB LED light source and lenses.
