Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulated flame lamps with fixed lamp beads require a large number of beads, increasing cost and complicating control, while those without motors or electromagnetic coils lack structural simplicity and effective simulation.
Innovation Solution
A simulated flame lamp design using two illuminants, one always on and the other controlled intermittently, with an integrated structure and reduced bead count, achieving a dancing flame effect through differential flame projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of lamp beads are arranged on a fixed flame sheet to simulate flame dancing, then the simulation effect is improved, but the cost increases and control complexity increases
Solution Approach 1:
The invention divides the flame simulation into two distinct projection zones: a lower section illuminated by a first illuminant and an upper section illuminated by a second illuminant. This segmentation allows each illuminant to control a specific portion of the flame effect, reducing the total number of lamp beads needed while maintaining realistic simulation. The control IC manages these segmented zones independently, simplifying overall control complexity.
Solution Approach 2:
The invention transitions from a two-dimensional arrangement of multiple lamp beads on a flat flame sheet to a three-dimensional spatial distribution using two illuminants positioned at different heights. The first illuminant projects light to the lower section while the second illuminant projects to the upper section, creating a vertical dimension in light projection. This dimensional change reduces component count while achieving comprehensive flame coverage.
2Reliability
If multiple lamp beads are arranged to simulate flame dancing, then the simulation effect is improved, but the cost increases
Solution Approach 1:
The flame simulation is segmented into lower and upper sections, each served by a dedicated illuminant. This segmentation eliminates the need to populate the entire flame sheet with numerous lamp beads, as only two strategically positioned illuminants are required to create the dancing flame effect across both zones.
Solution Approach 2:
Each illuminant serves multiple functions: the first illuminant creates the lower flame projection while the second illuminant creates the upper flame projection. Together, they simulate the complete dancing flame effect that would otherwise require many individual lamp beads distributed across the entire flame sheet area.
3Reliability
If a driving mechanism such as motor or electromagnetic coil is used to swing the flame sheet, then the flame burning effect is achieved, but the structure becomes complex
Solution Approach 1:
The invention replaces the mechanical driving mechanism (motor or electromagnetic coil) with an optical control system. Instead of physically swinging the flame sheet using mechanical forces, the dancing flame effect is achieved by controlling the illumination patterns of two illuminants. The control IC modulates the light emission to create the appearance of flame movement without any mechanical motion, thereby eliminating complex mechanical components.
Solution Approach 2:
Rather than physically replicating flame motion through mechanical movement of the flame sheet, the invention creates an optical copy or illusion of flame dancing through controlled illumination. The two illuminants, when modulated by the control IC, produce light patterns that mimic the visual appearance of dancing flames, achieving the same effect without mechanical complexity.

AI summary
A simulated flame lamp includes a dispersion lamp shade, a support having a mounting platform, a first illuminant, a second illuminant and a control IC. The first illuminant is configured to emit light toward a side wall of the dispersion lamp shade, and the second illuminant is located above the first illuminant and configured to emit light toward the side wall of the dispersion lamp shade. The first illuminant is always on when energized, and the light of the first illuminant is projected to a lower section of the side wall of the dispersion lamp shade; the control IC is configured to control the second illuminant to emit light at intervals so that the light of the second illuminant is projected to an upper section of the side wall of the dispersion lamp shade. The simulated flame lamp has simple structure, low cost and good simulation effect.
