Abstract

A table lamp including a base, a lamp handle, a lamp holder provided with a light source and an adjustment component. The base can be placed on a placement surface, and a bottom surface of the base is a curved surface. The adjustment component can adjust the center of gravity of the table lamp by varying the center of gravity thereof, to thereby change a contact position of the bottom surface of the base and the placement surface, and thus change the illumination angle of the lamp holder. Since this technical solution adjusts the illumination angle of the lamp holder by adjusting the center of gravity of the table lamp instead of rotating the lamp holder, it solves the problem of breakage of the connection part of the lamp handle and the lamp holder caused by rotation of the lamp holder.

First claim

The invention claimed is:

1. A table lamp, the table lamp comprising: a base, a lamp handle, a lamp holder provided with a light source and an adjustment component, wherein
the lamp handle is in fixed connection with the base, the lamp holder and the adjustment component, respectively;
the base can be placed on a placement surface, and a bottom surface of the base is a curved surface, and a center of gravity of the table lamp falls on the base;
the adjustment component is capable of adjusting the center of gravity of the table lamp by varying a center of gravity of the adjustment component, to thereby change a contact position of the bottom surface of the base and the placement surface, and thus make the illumination angle of the lamp holder change,
the adjustment component comprises: a lamp shank and poises,
one end of the lamp shank is in fixed connection with the lamp handle, and the poises can be attached to the lamp shank;
the center of gravity of the adjustment component can be varied by adjusting at least one of a number of the poises and positions of the poises on the lamp shank,
the poises are annular structures, and an opening is provided on a lateral surface of respective poises, a size of the opening being adjustable; and
the poises can be nested around the lamp shank by adjusting the size of the opening.

2. The table lamp according to claim 1 , wherein the base is provided with a cavity inside, and a fixed weight is arranged on a bottom of the cavity.

3. The table lamp according to claim 2 , wherein a position of the fixed weight on the bottom of the cavity can vary with a contact position of the bottom surface of the base and the placement surface.

4. The table lamp according to claim 1 , wherein the poises or the lamp shank has magnetism such that the poises can be attracted to the lamp shank.

5. The table lamp according to claim 1 , wherein the poises are annular structures, and the lamp shank is a cylindrical structure; a block is arranged on a lateral surface of the lamp shank, the block comprising: at least one of a fixed block and a moveable block, the fixed block is fixedly positioned on the lamp shank, and a variable position of the moveable block on the lamp shank; the poises are nested around the lamp shank and stuck on the lamp shank by means of the block.

6. The table lamp according to claim 5 , wherein
the moveable block is one of stuck on the lamp shank,
and attracted to the lamp shank.

7. The table lamp according to claim 1 , wherein the light source is a light emitting diode (LED) light source.

8. The table lamp according to claim 3 , wherein the fixed weight is made of sandstone.

9. The table lamp according to claim 3 , wherein the fixed weight is made of a fluid.

10. The table lamp according to claim 7 , wherein the table lamp further comprises: a power line,
both the base and the lamp handle are provided with a channel for the passage of the power line;
the power line sequentially passes through the channel in the base and the channel in the lamp handle, and is connected with the lamp holder.
