When the lamp body 6 lights a certain point on a specific dimension, the sphere 2 is shifted along the longitudinal direction, and various geographic information such as countries, cities, landforms and the like in the dimension can be explained.

In order to reduce scattering conditions in the light irradiation process as much as possible, so that the irradiation position is more accurate, the irradiation brightness is ensured, a light shield 61 is arranged on the periphery of the lamp body 6, and the light shield 61 is provided with a through hole facing the inner surface of the sphere 2.

When the swing center of the mounting seat 4 is not at the center of the sphere, the latitude driving of the mounting seat 4 is relatively complex, namely, the corresponding conversion relation between the swing angle and the latitude change is relatively complex based on the swing angle required by the swing center of the mounting seat 4 to be replaced to reach the target position. In order to simplify the calculation of the control module and to be able to control the angle of oscillation of the lamp body 6 relative to the sphere 2 in terms of latitude more precisely, the mounting 4 is rotatably connected to the mounting 3 in correspondence with the position of the sphere centre.
