[0016] See also Figure 1-5The present invention discloses an LED floor lamp, comprising a lampshade 1, a lamp post 3 and a chassis 4, wherein the lampshade 1, the lamp post 3 and the chassis 4 respectively constitute the main body of the floor lamp in the upper, middle and lower structural positions, an upper connector 2 and a lower connector 6 which can be installed by upper and lower docking are respectively provided between the lampshade 1 and the lamp post 3; a mounting ring 5 with a hollow screw wall structure is provided between the lamp post 3 and the chassis 4, a thread which docks with the screw wall of the mounting ring 5 is etched at the lower end of the lamp post 3, a middle hole 7 which is rotatably connected with the mounting ring 5 is provided at the middle opening of the chassis 4, a seat groove 8 is grooved on the inner side of the chassis 4, a counterweight block 11 which can be plugged into the notch of the seat groove 8 is provided at the lower end of the seat groove 8, four screw holes corresponding to the positions are provided on the surfaces of the counterweight block 11 and the seat groove 8, and bolts 12 for connecting and fixing the counterweight block 11 and the seat groove 8 are rotatably connected at the screw holes of the counterweight block 11, such a decomposed mounting structure can facilitate the management of components such as the counterweight block 11 and the chassis 4, and is easy to install and transport.

[0017] Preferably, the upper connector 2 and the lower connector 6 are respectively sleeved with an upper ring 16 and a lower ring 14 in the middle, and the inner walls of the upper ring 16 and the lower ring 14 are longitudinally distributed with threads that can rotate and connect with each other. The upper connector 2 and the lower connector 6 are both hollow structures and are respectively provided with a lamp holder groove 17 and a bobbin 15.

[0018] To make the structure of the present invention more reasonable, as a preferred embodiment, the upper ring 16 and the lower ring 14 are sleeved with a middle ring 19 in the middle, and the upper end of the middle ring 19 has six ring walls 21 and a connecting ring 20 welded to the ring walls 21 extending obliquely.

[0019] The upper end of the lamp holder groove 17 is plugged with a lamp holder 18 , and the upper and lower ends of the lamp holder 18 are respectively slotted with a screw wall slot 28 for plugging and installing a light bulb and a wire plug hole 22 for docking with a cable port.

[0020] The upper end of the wire jack 22 is provided with an end block 23 made of conductive material, and an outer spring ring 27 is sleeved on the outer side of the screw wall slot 28, and a conductive ring shaft 26 with conductive spiral rings distributed on the surface is penetrated at the lower end. There is a gap in the middle of the end block 23 and the conductive ring shaft 26, and a contact piece 25 made of conductive material is horizontally arranged at the gap between the end block 23 and the conductive ring shaft 26, and a base shaft 24 for fixing the contact piece 25 in the position of the lamp holder 18 is provided at the left and right ends of the contact piece 25. After the bulb and the screw wall slot 28 are docked and installed, the conductive ring shaft 26 is elastically pressed together. After the conductive ring shaft 26 is stretched, it is electrically connected to the end block 23 by connecting with the contact piece 25. The telescopic compensation of the conductive ring shaft 26 and the outer spring ring 27 ensures that the connection structure of the bulb and the lamp holder 18 is stable. At the same time, the tight connection between the bulb and the lamp holder 18 can prevent moisture from eroding the internal electrical connection structure of the lamp holder 18.

[0021] The lampshade 1 has an inner cavity 29 slotted therein, and a T-shaped block 30 for docking and fixing with the connecting ring 20 is fixedly connected to the lower side wall of the inner cavity 29 , and a lamp groove 31 docking and installing with the lamp holder 18 is suspended in the middle after the inner cavity 29 docks with the connecting ring 20 .

[0022] A closed hot chamber 31 is provided at the upper end of the lamp trough 31, and the outer wall of the hot chamber 31 is made of glass and filled with nitrogen. A closed cold chamber 35 is provided at the top of the lamp trough 31, and a spiral rod 33 with a hollow cavity inside is provided in the middle of the hot chamber 31 and the cold chamber 35, and a hot chamber 32 is installed at the lower end of the spiral rod 33. During the light emission and heating process of the bulb in the lamp trough 31, the heat emitted by the light source is introduced into the interior through the hot chamber 32 and the outer wall glass of the hot chamber 31. The nitrogen in the hot chamber 31 expands due to the heat and generates a pressure higher than that of the cold chamber 35. Then, the gas in the hot chamber 31 is affected by the air pressure and moves upward to the cold chamber 35 through the cavity of the spiral rod 33. The gas in the cold chamber 35 is not affected by the heating of the light source, and the gas temperature cools down over time. After cooling, the gas contracts to generate a pressure lower than that of the hot chamber 31 and moves downward to the cold chamber 31 to complete the periodic cycle.

[0023] The surface of the screw rod 33 is provided with a thread groove inclined at an angle of 30 degrees, and a metal ring 34 is sleeved in the middle of the screw rod 33 and is connected to the thread groove of the screw rod 33 and rotates. A magnetic piston 36 is provided in the hollow cavity of the screw rod 33 and is suspended and adsorbed with the metal ring 34. The magnetic piston 36 is made of neodymium iron boron. The strong magnetic properties of the neodymium iron boron material of the magnetic piston 36 ensure that the adsorption structure of the metal ring 34 and the magnetic piston 36 is stable.

[0024] The side wall of the metal ring 34 is fixedly connected to a swing arm 37, and the right end of the swing arm 37 is movably connected to a brush head 38 that fits tightly against the inner wall of the inner cavity 29, and soft bristles are evenly distributed on the surface of the brush head 38. When the hot chamber 31 and the cold chamber 35 move up and down, the internal magnetic piston 36 is longitudinally changed in position by the movement of the gas. When the magnetic piston 36 moves, it drives the external metal ring 34 to rotate along the spiral rod 33, and the swing arm 37 and the brush head 38 are linked by the rotation of the metal ring 34. The brush head 38 moves to brush the inner wall of the inner cavity 29 with soft bristles.

[0025] A battery seat 13 for docking and installing with a battery is provided in the middle part of the seat groove 8 and the counterweight block 11, and a power cable 10 for plugging with a plug is electrically connected to the outside of the battery 13, and an outlet groove 9 for placing the power cable 10 is provided on the outside of the seat groove 8. After the battery seat 13 is docked with the battery, the upper port can pass through the middle part of the lamp post 3 and be electrically connected to the spool 15 through the cable, and the spool 15 can be electrically connected to the terminal block 23 at the wire jack 22 through the docking of the cable.

[0026] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above invention, which fall within the scope of protection of the present invention.
