Dynamic flame forming method, flame simulation structure and electronic candle

Abstract

The invention provides a dynamic flame forming method. The dynamic flame forming method is characterized by comprising the following steps: projecting light emitted by a plurality of groups of light sources onto a flame sheet, wherein at least one group of light sources is used as an inner flame light source, and dynamic inner flame is formed through a position change and / or a light and shade alternating change of inner flame projection light and shadows formed by the inner flame light source on the flame sheet; taking at least one group of light sources of which the light emitting colors aredifferent from those of the inner flame light sources as outer flame light sources, wherein outer flame projection shadows formed by the outer flame light sources on the flame sheet are located at theedges and / or above the inner flame light sources; and forming the dynamic outer flame through the position change and / or the light and shade alternating change of the outer flame projection light andshadows. According to the method, the flame simulation fidelity can be improved, the structure can be simplified, and energy consumption can be reduced. The invention also provides a flame simulationstructure for realizing the method, and an electronic candle comprising the flame simulation structure.

Description

technical field [0001] The invention relates to the technical field of flame simulation, in particular to a dynamic flame forming method, a flame simulation structure and an electronic candle. Background technique [0002] In order to create a special atmosphere such as romance and warmth, people use candles as decorations; traditional candles achieve lighting through the flame formed by burning, but the candles wear out quickly, which is not conducive to energy saving and environmental protection, and the heat and odor generated during the burning process will also reduce the user's safety. comfort, and the candle flame may ignite surrounding items and pose a safety hazard. In order to avoid these problems, in recent years, people have used electronic candles instead of traditional candles for scene layout; the existing electronic candles project the light from the light source onto the flame sheet, and the swaying of the flame sheet causes the light and shadow to shake, th...

AI Technical Summary

Problems solved by technology

[0003] Existing electronic candles only project a single light and shadow to simulate flames, but flames usually have outer flames and inner flames, and existing electronic candles do not have the function of simulating outer flames and inner flames at the same time, so the fidelity of electronic candle flame simulation has a lot of room to grow

[0004] In addition, existing electronic candles still have disadvantages such as high energy consumption and limited placement angles.

For example, when the electronic candle is placed obliquely, there may be technical problems such as the failure of the swing mechanism and the failure of the flame sheet to swing normally, resulting in the inability to form a swaying flame
