Embodiment Construction

[0007] Such as figure 1 Shown is the appearance of a moon phase instrument viewed from the front. The figure includes a sphere part 1, a bracket part 2 and a background part 3, and the sphere part 1 includes a shadow ball and the moon.

[0008] Here, the shadow ball is a transparent glass ball whose exterior is decorated with a gradient of black, depicting the shadow of the white sphere under the sun, which makes a part of the transparent glass ball into opaque black; the so-called under the sun means only the sun Under the background, that is, without the effect of background light, the gradual black gradient process is mainly manifested near a large circle, and it quickly becomes completely black when it crosses the large circle, and there is no anti-white in the completely black shadow.

[0009] Here, the moon is a sphere slightly smaller than the shadow sphere, and its appearance depicts the light and dark changes on the surface of the real moon under the sunlight. This ki...

Abstract

The invention provides a teaching demonstration instrument for indicating lunar phase changes. The instrument comprises a ball portion 1, a support portion 2 and a background portion 3. When a crank is rotated, we can see changes of simulated lunar phases from the front.

Description

technical field [0001] Specifically, the invention is an instrument for demonstrating moon phase changes. Background technique [0002] In reality, the moon phase instrument relies on the light source, but it is not clear to demonstrate the moon phase in the daytime environment. Contents of the invention [0003] The invention overcomes the shortcomings and deficiencies in the prior art, and provides a device capable of demonstrating moon phase changes under bright light. [0004] The technical solution of the present invention is: comprising a sphere part, a bracket part and a background part, the sphere part includes a shadow ball and the moon, the shadow ball is a transparent glass ball, its exterior is decorated with a gradient black, depicting white under the sun The shadow of the sphere; the surface of the moon depicts the light and shade changes of the surface of the real moon under the sunlight; the shadow ball is sleeved outside the moon with a gap between them; ...
