The rotating electrical machine, the first laser tube 106, the second laser tube 107, and the LED lamp bead 123 are all electrically connected to the main control circuit board 105. The main control circuit board 105 is provided with a signal receiving antenna, and the signal receiving antenna is used for receiving a control signal sent by an external control terminal (such as a remote controller, a mobile phone, etc.). Based on the corresponding control signal, the main control circuit board 105 controls the rotation speed of the movable projection sheet 111 and the illumination states of the first laser tube 106, the second laser tube 107, and the LED lamp bead 123.

The projection principle of the electronic candle in the present invention is roughly as follows:

The laser light emitted by the first laser tube 106 sequentially passes through the movable projection sheet 111 and the first stationary projection sheet 117, thereby the current sub-pattern of the third pattern on the movable projection sheet 111 (pattern 1 to pattern 6) One of the ones) and the first pattern on the first stationary slide 117 are overlaid onto an external projection receptor (wall, screen, etc.). For example, in one embodiment, the patterns 1 to 6 are respectively six different flower shapes, and the first pattern is a starry sky pattern, and when the first laser tube 106 is illuminated, the projection receptor The picture shows a beautiful picture of flowers floating in the sky. As the active slide 111 rotates, the shape of the flowers keeps switching. What's even more amazing is that if Patterns 1 through 6 are sequentially set to the shape of the flowers from six different time points, from the time they are to be fully bloomed, we can enjoy the light and shadow process of blooming flowers in the sky.

Similarly, the laser light emitted by the second laser tube 107 sequentially passes through the third stationary projection sheet 110 and the second stationary projection sheet 118, thereby the fourth pattern and the second pattern on the third stationary projection sheet 110. The second pattern on the stationary slide 118 is overlaid onto an external projection receptor (wall, screen, etc.). For example, in a specific embodiment, the fourth pattern is a cloud pattern, and the second pattern is a moon pattern. When the second laser tube 107 is opened, a projection cloud appears on the projection receptor. Beauty of the month Wonderful picture.

It is conceivable that when the first laser tube 106 and the second laser tube 107 are simultaneously illuminated, the projection receptor will exhibit a more beautiful and more dreamy light and shadow picture.

In this embodiment, the first laser tube 106 and the second laser tube 107 are multi-color laser tubes, and the main control circuit board 105 can control their illuminating colors, thereby making the projection picture more dynamic and beautiful.
