Once the lampshade has descended to a suitable height, the servo motor is turned off, allowing the user to repair or replace the lamp tubes from the ground without climbing to a height, making repairs convenient and safer.

Description

Technical Field

[0001] This utility model belongs to the field of chandelier technology, specifically relating to an LED chandelier with multi-color display function. Background Technology

[0002] LED chandeliers are lighting fixtures suspended from indoor ceilings, combining practicality and decoration. Their core features include energy efficiency, long lifespan, and diverse designs.

[0003] Existing LED lights are generally suspended directly from the ceiling via lamp holders. When some LED lamp tubes malfunction and need repair or replacement, workers need to climb to a high place, which is not only inconvenient but also poses certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide an LED chandelier with a simple structure and reasonable design and a multi-color display function in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An LED chandelier with multi-color display function includes a lampshade. Multiple lamp tubes are installed at the bottom of the lampshade. A male plug that is electrically connected to the lamp tubes is fixedly connected to the center of the top of the lampshade. A female plug is provided above the male plug. A mounting base is fixedly connected to the female plug through a connecting structure. A receiving cavity is provided inside the mounting base. Two sets of winding structures are symmetrically installed in the receiving cavity. A traction cable is fixedly connected to the winding structure. The end of the traction cable away from the winding structure passes through the bottom wall of the mounting base and is fixed to the upper surface of the lampshade.

[0007] As a further optimization of this utility model, a control circuit board is fixedly installed inside the lampshade, and multiple lamp tubes are mounted on the control circuit board. The lamp tubes are electrically connected to the male plug through the control circuit board.

[0008] As a further optimization of this utility model, the connection structure is a connecting pipe disposed between the mounting base and the female plug, with both ends of the connecting pipe fixed to the female plug and the mounting base respectively, and a wire connected to an external power source passing through the connecting pipe, the bottom end of the wire being electrically connected to the female plug.

[0009] As a further optimization of this utility model, the top periphery of the mounting base is bent outward to form a mounting plate, and multiple fixing holes are provided on the mounting plate. External expansion bolts pass through the fixing holes, penetrate the mounting plate, and are anchored and fixed to the building ceiling.

[0010] As a further optimization of this utility model, the winding structure includes two sets of brackets fixedly installed on the bottom wall of the cavity. A winding shaft is rotatably connected between the two brackets in each set, and a servo motor for driving the winding shaft to rotate is installed on the bracket.

[0011] As a further optimization of this utility model, guide tubes are fixedly connected to both sides of the female plug, the top end of the traction cable is fixed to the winding shaft, and the bottom end of the traction cable passes through the guide tube and is fixed to the top wall of the lampshade.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The male connector winds up the traction cable via a take-up shaft, and, guided by a guide tube, connects to the female connector at the bottom of the mounting base to supply power to the control circuit board and the lamp. When some lamps malfunction due to prolonged use and require repair or replacement, the user can start the servo motor to drive the take-up shaft to rotate, unwinding the traction cable. At this time, the lamp cover moves downward under its own weight, causing the male connector to disengage from the female connector. Once the lamp cover has moved to a suitable height, the servo motor is turned off, allowing the user to repair or replace the lamp on the ground without climbing to a high place, making repairs more convenient and safer.

[0014] 2. During the maintenance of the lamp, since the male and female plugs are disconnected, the lamp and control circuit board are never energized. This can minimize the risk of electric shock to the staff due to a sudden power supply from an outsider during the maintenance process. Attached Figure Description

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 - Figure 4 As shown, an LED chandelier with multi-color display function includes a lampshade 1, a control circuit board 2 fixedly installed inside the lampshade 1, and multiple lamp tubes 3 installed on the control circuit board 2. The lamp tubes 3 are LED lights, and the multiple lamp tubes 3 are of different colors. This allows the user to control the lamp tubes 3 connected to the circuit through the control circuit board 2, adjust the overall color of the LED chandelier, and realize the multi-color display function of the LED chandelier.

[0023] A male plug 4 is fixedly connected to the center of the top of the lampshade 1. Multiple lamp tubes 3 are electrically connected to the male plug 4 through the control circuit board 2. A female plug 5 is provided above the male plug 4. A mounting base 7 is provided above the female plug 5. The top circumference of the mounting base 7 is bent outward to form a mounting plate. Multiple fixing holes 8 are provided on the mounting plate. External expansion bolts pass through the fixing holes 8 and are anchored to the building ceiling.

[0024] A connecting tube 6 is provided between the female plug 5 and the mounting base 7. The two ends of the connecting tube 6 are fixed to the female plug 5 and the mounting base 7 respectively. A wire connected to an external power source is passed through the connecting tube 6. The bottom end of the wire is electrically connected to the female plug 5. When the male plug 4 is plugged into the female plug 5, the control circuit board 2 and the lamp tube 3 can be powered by an external power source.

[0025] The mounting base 7 has a receiving cavity 9. Two sets of brackets 10 are fixedly installed on the bottom wall of the receiving cavity 9. A take-up shaft 11 is rotatably connected between the two brackets 10 in each set. A servo motor 12 for driving the take-up shaft 11 to rotate is installed on the bracket 10. A traction cable 13 with one end fixedly connected to the take-up shaft 11 is wound around the take-up shaft 11. When the servo motor 12 drives the take-up shaft 11 to rotate, the traction cable 13 can be wound or unwound.

[0026] Guide tubes 14 are fixedly connected to both sides of the female plug 5. After the end of the traction cable 13 away from the winding shaft 11 passes through the bottom wall of the receiving cavity 9, it slides through the corresponding guide tube 14 and is fixed to the upper surface of the lamp cover 1 on both sides of the male plug 4, so that when the winding shaft 11 winds or unwinds the traction cable 13, it can drive the lamp cover 1 to rise and fall.

[0027] It should be noted that, in use, this LED chandelier with multi-color display function first involves attaching the top ends of the two traction cables 13 to the two winding shafts 11, and then sliding the bottom ends of the two traction cables 13 through the bottom wall of the receiving cavity 9, and finally through the connecting tube 6 installed on the side wall of the female plug 5, fixing it to the top wall of the lampshade 1. At this point, the mounting base 7 can be fixed to the building ceiling by using external expansion bolts in conjunction with the fixing holes 8 opened on the mounting plate. Then, the servo motor 12 is started, which drives the winding shaft 11 to rotate, winding up the traction cables 13. During the winding process, the traction cables 13 will pull the lampshade 1 upward, and with the limiting and guiding effect of the guide tube 14, the male plug 4 is inserted into the female plug 5, so that the control circuit board 2 and the lampshade 1 are connected. 3. When connected to an external power source, the user can issue control commands to the control circuit board 2 via an external remote control device to adjust the number of lamps 3 connected to the external power source and adjust the overall color of the LED chandelier to achieve the multi-color display function of the LED chandelier. When some lamps 3 malfunction due to long-term use and need to be repaired or replaced, the user can start the servo motor 12 to drive the winding shaft 11 to rotate in the opposite direction. During the reversal of the winding shaft 11, the traction cable 13 is unwound. At this time, the lampshade 1 moves downward under its own gravity, causing the male plug 4 to disengage from the female plug 5. After the lampshade 1 moves down to a suitable height, the servo motor 12 is turned off, and the user can repair or replace the lamps 3 on the ground without climbing to a high place, which is not only convenient but also safer.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
