Embodiment one:

The first embodiment provides a flame simulation component of an electronic candle. The flame simulation component simulates the effect of real flame flickering through the control of the light emitting element.

Please refer to FIG. 1, the flame simulation assembly includes a flame sheet 100 for simulating the shape of a flame, at least one light emitting element 200 for simulating a flame effect and a circuit board 300 for controlling the light emitting element 200, the light emitting element 200 and the circuit board 300 Connection, one light emitting element 200 has at least two light emitting chips, the light emitting side of the light emitting element 200 is set towards the flame sheet 100, and the chips of the same light emitting element 200 illuminate different areas on the same side of the flame sheet 100.

The circuit board 300 controls different chips of the same light-emitting element 200 to turn on and off, so that the area where the chip irradiates on the flame sheet 100 is turned on and off, thereby creating the effect of flickering candlelight.

The on and off of the chip can be regular or irregular, depending on the desired visual effect. Usually, the chips can be turned on and off alternately, so that the flame sheet 100 looks more like a flickering candle.

Please refer to FIGS. 2 and 3 , when the flame sheet 100 is in normal use, the outer wall on the same side of the flame sheet 100 is divided into four areas: upper, lower, left, and right.

In this embodiment, the two chips of at least one light emitting element 200 respectively illuminate the left and right areas on the same side of the flame sheet 100 . As shown in FIG. 2 , there are two chips A and B inside the light emitting element 200 , and the two chips A and B are substantially horizontally arranged side by side. When the two chips A and B emit light, the areas on the flame sheet 100 illuminated by them are as shown in A and B (the left and right areas shown by the dotted lines) in Figure 3. When the chip is on and the A chip is off, it can form a visual effect of the candle shaking left and right.

Similarly, in this embodiment, two chips of at least one light-emitting element 200 can respectively illuminate the upper and lower areas of the same side of the flame sheet 100 to create a visual effect of the flame swinging up and down.

As shown in FIG. 2 , there are two chips C and D inside the light emitting element 200 , and the two chips C and D are substantially horizontally arranged side by side. When the two chips C and D emit light, the areas that they irradiate on the flame sheet 100 are shown in Figure 3 as shown in C and D (the upper and lower areas shown by the dotted lines). When the chip is on and the C chip is off, a visual effect of candlelight shaking up and down can be formed.

In addition to the four directions of up, down, left, and right, the placement direction of the chip can also be arranged arbitrarily according to the desired visual effect, thereby changing the area irradiated on the flame sheet 100 to form different visual effects.

The dotted areas A, B, C, and D in Fig. 3 only roughly demonstrate where the light of the chip is. In fact, there is no specific boundary for the diffusion of light, and the specific irradiation range cannot be shown here.

The flame simulation component adopts a light-emitting unit with at least two chips. The two chips illuminate different areas on the same side of the flame sheet. By controlling the chips to turn on and off, a visual effect of the flame swinging in various directions is formed.
