[0034] The present invention provides an LED chandelier. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] See also Figure 1 , Figure 2 The present invention provides an LED chandelier, which includes a hanging part 3, a shell 2 arranged at the bottom of the hanging part 3 in a horizontal state, two end plates 5 respectively arranged at both ends of the shell 2, a lamp body 6 connected to the bottom of the end plates 5 at both ends, an inner shell 9 with an LED driver (not shown in the figure) arranged therein, and a buckle device 8 arranged on the inner side or outer side of the end plate 5 and located inside the inner shell 9 and above the lamp body 6. In this embodiment, a hanging wire is used.

[0036] like Figure 3 , Figure 5 , Figure 7 As shown, the end plates 5 are fixed to the two ends of the inner shell 9 by screws; the outer shell 2 is provided with a receiving groove (not marked in the figure) in which the inner shell 9 can be placed and the opening faces downward, so that the inner shell 9 can be placed into the receiving groove from bottom to top; the outer shell 2 is provided with a power-carrying copper sheet 94, and the top of the inner shell 9 is provided with a conductive column 91 which is electrically connected to the LED driver and the lamp body 6 in sequence and can contact the power-carrying copper sheet 94 accordingly. When the inner shell 9 is placed in the receiving groove of the outer shell 2 and moved up to the right position, the conductive column 91 contacts the power-carrying copper sheet 94 to achieve electrical connection, thereby enabling the LED driver to provide power to the lamp body 6.

[0037] Specifically, Figure 1 , Figure 3 , Figure 7 As shown, the buckle device 8 includes two movable clamping plates 81 and a driving mechanism for driving the movable clamping plates 81 to move outward, and the receiving slot of the housing 2 is provided with a clamping block 21 located below the movable clamping plates 81 and clamped to the movable clamping plates 81. The movable clamping plates 81 are symmetrically arranged about the vertical plane.

[0038] The snap-fit ​​device 8 can be fixed on the end plate 5 by screws, and the end plate 5 is fixed on both ends of the inner shell 9. When the inner shell 9 is placed in the receiving groove of the outer shell 2 and moved up to the position, the movable snap-fit ​​plate 81 is located above the block 21 at this moment, and then the movable snap-fit ​​plate 81 is urged to move horizontally outward (or on both sides) by the driving mechanism, so that the movable snap-fit ​​plate 81 contacts the block 21, and the snap-fit ​​device 8 is supported by the block 21, thereby ensuring that the inner shell 9 is fixed to the outer shell 2, and the inner shell will not be separated from the receiving groove and fall off. Moreover, during installation and maintenance, the movable snap-fit ​​plate 81 is moved horizontally by operating the driving mechanism, thereby urging the movable snap-fit ​​plate 81 to engage or disengage with the block 21, so that the inner shell can be directly installed on the outer shell or removed from the outer shell.

[0039] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the driving mechanism includes a spring 83, a cover plate 84, and a vertically movable positioning slider 82; the movable positioning plate 81 is provided with a positioning column 812 and a horizontally arranged second slide groove 811, and the end plate 5 is correspondingly provided with a first limit block 56 slidably connected to the second slide groove 811.

[0040] The two ends of the spring 83 are respectively fixed to the top of the positioning slider 82 and the end plate 5; specifically, the top of the positioning slider 82 is provided with a limiting column 823 suitable for one end of the spring 83 to be inserted into, and the end plate 5 is provided with a limiting groove 53 suitable for the other end of the spring 83 to be inserted into, and the cover plate 84 is fixedly connected to the end plate 5 by bolts and covers the limiting groove 53, covering the limiting groove and the positioning slider 82, thereby ensuring that the positioning slider 82 can only move vertically.

[0041] The positioning slider 82 is provided with a third slide groove 822 which is slidably connected to the positioning column 812; the two third slide grooves 822 are symmetrically arranged and are V-shaped (or inverted eight-shaped); the cover plate 84 is arranged on the outer side of the positioning slider 82 and fixed to the end plate 5; the positioning slider 82 is provided with a toggle block 821 which is integrally formed therewith.

[0042] The positioning slider 82 is driven to move in the height direction by manually moving the toggle block 821 up and down. When the positioning slider 82 moves up, it compresses the spring 83, and at the same time, the two movable clamping plates 81 move inwards through the sliding of the positioning column 812 relative to the third slide groove 822 (that is, the two movable clamping plates move closer to each other), so that the buckle connection between the movable clamping plate 81 and the clamping block 21 is released, so that the inner shell can be easily separated from the receiving groove of the outer shell.

[0043] The toggle block 821 is toggled upward, and the inner shell 9 is placed in the receiving groove of the outer shell 2. After it is moved up to the right position, the toggle block 821 is released, and the positioning slider 82 and the toggle block 821 are moved downward under the elastic force of the spring 83. At this moment, the two movable positioning plates 81 move outward (that is, the two movable positioning plates move away from each other) through the sliding of the positioning column 812 relative to the third sliding groove 822, so that the movable positioning plates 81 and the card block 21 are snap-fitted. Figure 3 , Figure 7 As shown, the inner shell and the outer shell are fixed to each other.

[0044] When the buckle device is arranged on the outer side surface of the end plate, the cover plate may be provided with an opening suitable for the up and down movement of the toggle block.

[0045] like Figure 1 , Figure 5 , Figure 6 As shown, when the buckle device 8 is arranged on the inner side of the end plate 5, the end plate 5 is provided with a limiting hole 55 suitable for the up and down movement of the toggle block 821. The end plate 5 is horizontally provided with a second limiting block 54 in an inverted L shape and slidably connected to the movable locking plate 81.

[0046] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, the lamp body 6 includes an arc-shaped reflector 1, a light-transmitting plate 63, an LED light strip 61 and a lamp housing 62; the two ends of the lamp housing 62 are respectively fixed to the end plate 5, and the top of the lamp housing 62 is provided with a first slide groove (not marked in the figure) slidably connected to the light-transmitting plate 63; the LED light strip 61 is arranged below the light-transmitting plate 63, and the two ends of the reflector 1 are respectively fixed to the end plate 5 and located above the light-transmitting plate 63, so that when the LED light strip is lit, the light can be emitted through the light-transmitting plate 63 and reflected by the reflector 1, thereby realizing the lighting effect of the LED chandelier and increasing the lighting range.

[0047] like Figure 3 , Figure 4 As shown, the end plate 5 is provided with a first slot 51 suitable for inserting the two ends of the reflector 1 and a second slot 52 suitable for inserting the two ends of the lamp housing 62 .

[0048] Specifically, Figure 1 , Figure 3 , Figure 7As shown, the hanging part 3 is threadedly connected with a screw 31; the top of the shell 2 is provided with a fourth slide groove 22 which is slidably connected with the screw 31. After the screw 31 is slid into the fourth slide groove 22 and moved to a suitable position along the length direction of the shell 2, the bottom end of the hanging part 3 is screwed into the top of the screw 31 until the bottom end of the hanging part 3 abuts against the top surface of the shell 2, and the shell is clamped by the bottom end of the hanging part and the screw, so as to achieve a fixed connection between the hanging part and the shell to prevent the shell from sliding relative to the hanging part and the screw. Such a sophisticated design makes it convenient for the staff to install the shell on the hanging part through the screws after installing the hanging part, and also makes it convenient for the staff to quickly and easily disassemble the shell for maintenance. In this embodiment, a hanging wire is used, and the bottom end of the hanging wire is provided with a connecting part which is threadedly connected with the screw and can rotate relative to the hanging wire. The connecting part is trumpet-shaped and provided with a threaded inner cavity, and the hanging wire is clamped in the inner cavity of the connecting part.

[0049] The outer shell 2 and the inner shell 9 are both made of aluminum profiles, which are light, strong and decorative, so that the hanging member 3 can hang the outer shell and the inner shell stably for a long time. The outer shell and the inner shell can be guide rails.

[0050] Specifically, Figure 1 As shown, the outer shell 2 is fixed with an end cover 4 located outside the end plate 5. The end cover 4 can be made of, but is not limited to, plastic. After the inner shell 9 is snap-fitted with the outer shell 2, the end plate 5 is located at both ends of the inner shell and the outer shell, and then the end cover 4 is used to completely cover the end plate 5, and is covered on the outer shell 2 and the end plate 5 by an interference fit connection, which is convenient for installation and disassembly, and ensures that the inner shell will not move horizontally (along the length direction) relative to the outer shell.

[0051] Specifically, Figure 7 , Figure 8 As shown, the outer shell 2 is provided with an iron block 95 located above the inner shell 9, and the top of the inner shell 9 is provided with a magnet 96 arranged corresponding to the iron block 95. The magnetic attraction effect is adopted to strengthen the relative fixation between the inner shell 9 and the outer shell 2, and combined with the snap-fit ​​fixing effect of the snap-fit ​​device 8, a double protection effect is provided to ensure that the inner shell and the outer shell are firmly fixed together.

[0052] A rubber seat 92 is provided at the top of the inner shell 9. The rubber seat 92 is made of PA46 (polybutylene adipamide) material, which has the advantages of flame retardancy, high temperature resistance, long service life and excellent mechanical properties. The conductive column 91 is an elastic conductive column and is fixed to the rubber seat 92; the magnet 96 is provided on the rubber seat 92 and connected to the inner shell 9 by bolts. A slot suitable for placing the magnet 96 is provided on the top of the rubber seat 92, and a through hole is provided corresponding to the magnet 96. The bolt passes through the through hole and is connected to the inner shell 9, and then the magnet 96 is used to fix the rubber seat 92 on the top of the inner shell 9, and the magnet 96 can be magnetically attracted to the iron block 95, providing an upward magnetic force, thereby reducing the pressure of the movable card plate 81 of the snap device on the card block 21. The conductive column 91 passes through the rubber seat 92 and the inner shell 9 and is electrically connected to the LED driver.

[0053] The housing 2 is provided with a fifth slide 23 and fixed bars 93 slidably connected to the fifth slide 23 on both sides. The fixed bars 93 are made of PC (polycarbonate) material and have the characteristics of heat resistance, impact resistance, good flame retardancy, high strength and excellent insulation performance. The fixed bars 93 are provided with fixed slides (not marked in the figure) slidably connected to the energized copper sheet 94 and the iron block 95. The fifth slide and the fixed slide are designed to facilitate the placement of the energized copper sheet 94, the iron block 95 and the fixed bars 93, and the installation is also very convenient.

[0054] One end of the current-carrying copper sheet 94 can be connected to a power supply line by welding, and the power supply line is connected to the mains through the outer end of the housing. Of course, the end cover 4 can be provided with an opening suitable for the power supply line to pass through.

[0055] like Figure 3 , Figure 4 As shown, the end plate 5 is provided with a wire groove 57 connected with the first slot 51 and the second slot 52 along the height direction. Since a gap is left between the end of the lamp housing 62 and the second slot 52 of the end plate 5, the inner housing 9 is also provided with a receiving groove with an opening facing downward. Therefore, the wires connected to the LED light strip 61 pass through the gap and are routed along the wire groove, and then pass through the reflector 1 to be connected to the LED driver of the inner housing 9.

[0056] like Figure 7 , Figure 8 As shown, openings 97 suitable for the movable locking plates of the locking device 8 to extend out are formed at both ends of the inner shell 9 .

[0057] like Figure 1 , Figure 3 , Figure 5 , Figure 7As shown, during maintenance work, first remove the end covers 4 at both ends of the LED chandelier, then operate the snap-fit ​​devices 8 at both ends, and at the same time push the toggle block 821 upward to push the movable snap-fit ​​plates 81 closer to each other, release the snap-fit ​​connection between the inner shell 9 and the outer shell 2, and without affecting the outer shell and the power supply line, not only take the inner shell out of the accommodating groove of the outer shell, but also disconnect the electrical connection between the conductive column 91 and the energized copper sheet 94; then loosen the screws on the end plate 5 to loosen the end plate 5 at both ends of the inner shell. At this moment, the lamp shell 62 and the inner shell 9 are separated from the end plates, which is convenient for the staff to replace the LED light strip 61 and the LED driver without completely disassembling the LED chandelier from the high hanging parts, thereby reducing the difficulty of maintenance.

[0058] In summary, the present invention provides an LED chandelier that can complete the snap connection between the inner shell and the outer shell and ensure electrical connection between the conductive column and the energized copper sheet, which is convenient and quick to install and disassemble and easy to replace the LED light strip and driver.

[0059] The present invention provides an inner shell to place electronic components such as an LED driver, and designs a special buckle device to fix the inner shell and the outer shell, so that the inner shell can be quickly and easily installed on the outer shell or removed from the outer shell, thereby realizing the replacement of LED light strips and LED drivers and improving maintenance efficiency.
