[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0027] In daily life, the floor lamp is often used as local lighting, without overall lighting, but with the convenience of movement. It is very practical for creating various local atmospheres. If the lighting mode of the floor lamp is directly downward projection, it is suitable for activities such as reading which need concentration. If it is indirect lighting, the overall light change can be adjusted.

[0028] However, some floor lamps do not have height adjustment function, and some have height adjustment devices, but these height adjustment devices are not safe and reliable. The common height adjustment device is a telescopic rod matched with a lock catch. The disadvantage of this structure is that when the lock catch is unlocked, the rods can smoothly and freely slide. At this time, under the external force of the user or the gravity of the lamp, the sliding speed between the two rods will be relatively fast, which is easy to cause danger and cannot be more closely applied to people's daily life.

The lamp rod assembly 10 comprises at least two lamp rod bodies 11 and 12 which are mutually sleeved and can slide relative to each other. The lifting assembly 40 is installed inside the lamp rod body 11 located at the outer side.

[0030] The lifting assembly 40 comprises a fixed connecting rod 41, a linkage screw rod 42 and a screw rod driving part 43. One end of the fixed connecting rod 41 is fixed to the bottom of the inner lamp rod body 12. One end of the linkage screw rod 42 is threadedly connected with the fixed connecting rod 41. The other end of the linkage screw rod 42 is drivingly connected with the screw rod driving part 43. The screw rod driving part 43 drives the linkage screw rod 42 to rotate, thereby driving the fixed connecting rod 41 to move up and down. In turn, the fixed connecting rod 41 drives the inner lamp rod body 12 to slide up and down relative to the outer lamp rod body 11. Thus, the lamp head 20 is lifted relative to the base 30 through the mutual up-and-down sliding of the two mutually sleeved and slidable lamp rod bodies 11 and 12.

[0031] The above scheme overcomes the problem that the conventional LED floor lamp without height adjustment function cannot adjust the height of the LED floor lamp. Moreover, the above scheme overcomes the problem that the conventional height adjustment device is not safe and reliable enough.
