a) Field of the Invention
The present invention relates to a table lamp having a lamp shade that can displace transversally and rotate by 360 degrees, and more particularly to a table lamp wherein a lower side of a connecting rod is provided with a slide base and when the slide base is sliding on a bottom seat, the connecting rod or the lamp shade will tilt due to a natural gravity. In addition, the lamp shade can displace transversally on the connecting rod or rotate by 360 degrees on the connecting rod by a rotation mechanism, thereby changing a location of the lamp shade.
b) Description of the Prior Art
A conventional table lamp is usually formed by a bottom seat, a connecting rod and a lamp shade. The connecting rod is connected on the bottom seat, the lamp shade is connected on the connecting rod and an interior of the lamp shade is provided with a light emitting element. As the connecting rod and the lamp shade of the table lamp are all fixed structure and cannot be adjusted, only a fixed light source can be provided without changing a location and a direction of the lamp shade.
Accordingly, the primary object of the present invention is to provide a table lamp, wherein an upper side of a bottom seat is installed with a slide base which is connected with a connecting rod, a rotation mechanism is connected at a top end of the connecting rod and a lamp shade is installed at an upper end of the connecting rod. When the connecting rod tilts, the slide base will shift naturally on the bottom seat due to a center of gravity, enabling the lamp shade to displace toward a direction opposite to the direction at which the slide base shifts; whereas, the lamp shade can displace transversally on the connecting rod or rotate by 360 degrees on the connecting rod by the rotation mechanism, so that the location of the lamp shade can be changed.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

a rotation mechanism 40, referring to
a transversal lamp shade 50 which is installed at an upper end of the connecting rod 30 and an interior of which is provided with an opened slide rail 51, with that a bottom end of the slide rail 51 is installed with a light emitting element 52 such as an LED or a light tube, and referring to
Referring to
In conclusion, the present invention is to provide a table lamp having a lamp shade that can displace transversally and rotate by 360 degrees, when the connecting rod of the table lamp tilts, the slide base will naturally shift on the bottom seat using the center of gravity. Therefore, the lamp shade can easily displace opposite to the direction at which the slide base shifts. In addition, the lamp shade can displace transversally on the connecting rod or rotate by 360 degrees on the connecting rod by the rotation mechanism, thereby changing the location.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
