Abstract
The invention relates to an astronomical globe, which consists of a geographical pattern ball, a built-in light-isolating disc fixing shaft and a base. The geographic pattern ball is formed by combining two hemispherical shells, and consists of a light ball shell, a globe map track film and a transparent black track film from inside to outside in sequence, the whole geographic pattern ball is almost in a black state due to the shielding of the outer transparent black film layer, and the pattern can be displayed only when a lamp in the built-in light-isolating disc is on. When the single-sided light on the built-in light-isolating disc is electrified and shines, half of the geographic pattern ball is illuminated and displayed, and the geographic pattern of the other hemisphere is in a black state due to the fact that the built-in light-isolating disc shields the interior from illumination, and day and night scenes of the earth can be displayed on the globe. Because the fixed shaft of the built-in light-insulating disc and the geographic pattern ball form an angle of 23.5 degrees which is consistent with the included angle between the revolution axis of the sun of the earth and the rotation axis of the earth, various astronomical scenes of the earth under the sun illumination can be displayed in real time.
