Drawings
Fig. 1 is a schematic structural diagram of the artificial rainbow device of the present invention.
Detailed Description
The following describes embodiments of the present invention in detail.
As shown in fig. 1, an artificial rainbow device includes a support 1, a light source 2, a refracting surface 3, and a reflecting surface 4. The height of the support 1 is adjustable, the light source 2 is rotatably arranged on the support 1, light emitted by the light source 2 is transmitted in the air and then enters the refraction surface 3 at an included angle smaller than 90 degrees with the refraction surface 3, preferably 45 degrees, and the refraction index of the refraction surface 3 is larger than that of the air. The refractive surface 3 and the reflective surface 4 are arranged in this order along the transmission direction of the outgoing light from the light source.
The artificial rainbow device provided by the embodiment can realize rainbow presentation indoors through the use of the bracket 1, the refraction surface 3 and the reflection surface 4, and the bracket 1 can be adjusted up and down to adjust the formation position of the rainbow. The holder 1 can be rotated in the horizontal direction to adjust the shape of the rainbow. The light source 2 is rotatably arranged on the bracket 1, and the formed rainbow shape can be adjusted. The refracting surface 3 may be a transparent glass plate. The reflecting surface 4 may be a flat mirror. The light source 2 is a light source that collimates to emit a beam of white light.
In one embodiment the artificial rainbow device further comprises a base 5, the holder 1, the light sources 2, the refractive surfaces 3 and the reflective surfaces 4 being detachably or fixedly arranged on the base 5.
When the rainbow making device is used, the light source 2 is turned on, emergent light from the light source 2 is transmitted in the air, enters the refraction surface 3 with the refractive index higher than that of the air at an angle of 45 degrees, is refracted for the first time to reach the reflection surface 4, is reflected for the first time on the reflection surface 4 to return to the refraction surface 3, and is refracted for the second time on the refraction surface 3 to form the artificial rainbow. The rainbow shape can be changed by adjusting the height of the support 1 or the light source 2 or rotating the support 1 or the light source 2.
Claims (6)
