Aurora effect projection device and control method thereof

Abstract

The invention discloses an aurora effect projection device and a control method thereof. At least one light transmitting element rotatably disposed relative to the light source assembly; A driving mechanism for driving rotation of each of the light transmitting elements; Centralized controller, the light source assembly and the drive mechanism are both signally connected to the centralized controller, wherein the light transmitting element is made of a transparent material of visible light, one side surface of the light transmitting element facing the light source assembly is a plane, and theother side surface is an uneven shape, and the light transmitting element is arranged on a propagation path of the light source assembly. When the light source is transmitted through the light transmitting element and projected onto the projection plane, it will produce banded, arc and radial artistic effects. When the light transmitting element rotates, the projection pattern is constantly changing, which is similar to the aurora effect. The aurora effect projection lamp of the invention has a simple structure, the aurora effect formed is more realistic, and the aurora effect can be projectedin a large area. The aurora effect projection lamp of the invention is simple in structure, and the aurora effect formed by the aurora effect projection lamp is more realistic.

Description

technical field [0001] The invention relates to an aurora effect projection device and a control method thereof. Background technique [0002] The aurora is a colorful luminous phenomenon, which occurs because the sun's charged particle flow (solar wind) enters the earth's magnetic field, and the brilliant and beautiful brilliance appears at night in the high altitudes near the earth's north and south poles. The aurora is regarded as one of the most beautiful wonders in nature. There are many kinds of aurora, including band, arc, curtain, radial, etc. These shapes are sometimes stable and sometimes change continuously. Moreover, the colors of the aurora are colorful and magnificent, and it is difficult for any colored pen to paint the playful and unpredictable dazzling light in the cold polar air. Sometimes the aurora appears for a very short time, just like a festival firework that flashes in the air and disappears without a trace; sometimes it can shine in the sky for s...

Problems solved by technology

[0003] At present, in order to simulate the visual effect of the aurora, one is to use a projector to project directly, but the projector has a limited viewing angle and low contrast, and the background brightness can be seen clearly in a dark environment, which affects the visual effect; the other is to follow the real The principle of aurora production in nature is to use accelerated electrons to generate aurora through a strong magnetic field, but it can only be realized in a very small area. It is usually simulated in principle in physical experiments and cannot be used for large-area aurora visual effect simulation.
