ABSTRACT:
The present invention relates to a terrestrial globe comprising a world map carrying spherical body rotatably supported around the Antarctic and Arctic points on a stand, and luminous bodies such as light emitting diodes mounted on selected points corresponding to major cities or like in the world map so that a group of the luminous bodies mounted on the points of same standard time are lit when these luminous bodies come into a plane defined by the front side of the stand, and particularly to a terrestrial globe in which the standard time of the zone defined by a group of the luminous bodies is displayed by a digital clock mounted on the stand. The present invention further relates to a terrestrial globe in which the luminous bodies mounted on the spherical body are electrically connected via a circular arc-shaped support arm for said spherical body to a source circuit arranged within the stand.
