[0032] like Figures 1 to 10As shown, a chandelier structure comprises a lamp holder 1, a light source board 2 and a lens 3 arranged in sequence; a pressure position 21 is provided on the light source board 2, and a pressure plate structure 31 corresponding to the pressure position 21 is provided on the side of the lens 3 close to the light source board 2; the lens 3 is mounted on the lamp holder 1, and the pressure plate structure 31 is pressed on the pressure position 21 to press the light source board 2 onto the lamp holder 1.

[0033] During installation, the light source board 2 is placed on the lamp holder 1, and then the lens 3 is installed on the lamp holder 1. The pressure plate structure 31 on the lens 3 will press on the pressure position 21 of the light source board 2, thereby pressing the light source board 2 on the lamp holder 1. In the chandelier structure of this embodiment, when installing the light source board 2, it is not necessary to tighten the screws 37. Instead, the light source board 2 is pressed and fixed on the lamp holder 1 when the lens 3 is installed, so that the installation efficiency of the light source board 2 is improved, thereby improving the efficiency of assembling the chandelier structure, reducing the time consumed, and being conducive to improving economic benefits.

[0034] In some specific embodiments, reference Figures 2 to 4 The pressure plate structure 31 includes a pressure column 311, and the pressure column 311 includes a pressure plate portion 3111 and a positioning portion 3112 arranged along its extension direction. The pressure plate portion 3111 is arranged on the lens 3, and a pressure plate step 3113 is formed between the pressure plate portion 3111 and the positioning portion 3112; a first positioning hole 211 is provided on the pressure receiving position 21, and the positioning portion 3112 is inserted into the first positioning hole 211, and the pressure plate step 3113 is pressed on the light source board 2. The positioning portion 3112 cooperates with the first positioning hole 211 to facilitate rapid positioning of the lens 3 and the light source board 2, which is conducive to further improving the installation efficiency of the light source board 2 and the assembly efficiency of the chandelier structure.

[0035] Specifically, the pressing plate portion 3111 and the positioning portion 3112 are both cylindrical, and the pressing plate portion 3111 and the positioning portion 3112 are coaxially arranged, and the positioning portion 3112 is located at one end of the pressing plate portion 3111 away from the lens 3. The diameter of the positioning portion 3112 is smaller than the diameter of the pressing plate portion 3111, so a pressing plate step 3113 is formed between the positioning portion 3112 and the pressing plate portion 3111. When assembling the chandelier structure, the positioning portion 3112 is inserted into the first positioning hole 211, and the relative position of the light source board 2 and the lens 3 can be easily fixed, and then the lens 3 is installed, so that the pressing plate step 3113 presses the light source board 2 on the lamp holder 1, which can not only improve the installation efficiency of the light source board 2 and the assembly efficiency of the chandelier structure, but also improve the position stability between the light source board 2 and the lens 3, so that the two are not easy to move relative to each other, which is conducive to maintaining the normal use of the chandelier structure.

[0036] In some other embodiments, the shapes of the pressing plate portion 3111 and the positioning portion 3112 are not necessarily cylindrical, and may be square columns or other shapes, as long as a pressing plate step 3113 is formed between the pressing plate portion 3111 and the positioning portion 3112 .

[0037] In some other embodiments, the pressing plate structure 31 includes a pressing block, a pressing plate or a structure in other shapes that can press the light source board 2 onto the lamp holder 1 .

[0038] In some specific embodiments, reference Figure 5 and Figure 6 A second positioning hole 12 is provided on one side of the lamp holder 1 close to the light source board 2, and the second positioning hole 12 corresponds to the first positioning hole 211 one by one. The positioning portion 3112 is inserted into the first positioning hole 211 and the second positioning hole 12, which is beneficial to quickly fix the lens 3, the light source board 2 and the lamp holder 1, and further improves the installation efficiency of the light source board 2 and the assembly efficiency of the chandelier structure.

[0039] The positioning portion 3112 is inserted into the first positioning hole 211 and the second positioning hole 12 to relatively position the lens 3, the light source board 2 and the lamp holder 1, and can limit the rotation or movement of the light source board 2 relative to the lamp holder 1 to ensure the normal use of the chandelier structure.

[0040] Specifically, the first positioning hole 211 is a through hole, penetrating the light source board 2 ; the second positioning hole 12 is a blind hole, not penetrating the lamp holder 1 , and opening toward the light source board 2 .

[0041] In some specific embodiments, reference Figures 2 to 5 There are multiple pressure points 21 distributed on the light source board 2, and multiple pressure plate structures 31 are provided on the side of the lens 3 close to the light source board 2. The multiple pressure plate structures 31 correspond to the multiple pressure points 21 one by one, which is more conducive to firmly pressing the light source board 2 on the lamp holder 1.

[0042] Correspondingly, each pressure position 21 is provided with a first positioning hole 211, the lamp holder 1 is provided with multiple second positioning holes 12, the multiple second positioning holes 12 correspond one-to-one to the multiple first positioning holes 211, and the lens 3 is provided with multiple pressure columns 311, the multiple pressure columns 311 correspond one-to-one to the multiple first positioning holes 211.

[0043] In some specific embodiments, a light source positioning structure 11 is provided on one side of the lamp holder 1 close to the light source board 2, and the light source positioning structure 11 defines a light source installation position 14 on the lamp holder 1, and the light source board 2 is arranged on the light source installation position 14. By providing the light source positioning structure 11, the light source board 2 can be quickly positioned on the lamp holder 1 first, and then pressed by the pressing plate structure 31, so as to further improve the efficiency and position accuracy of the installation of the light source board 2.

[0044] During installation, the light source positioning structure 11 defines a light source installation position 14 for the light source board 2. The light source board 2 can be directly placed on the light source installation position 14 during installation without having to be moved too much for adjustment, which is conducive to improving the installation efficiency of the light source board 2. The light source positioning structure 11 also serves as a limit for the light source board 2, preventing the light source board 2 from shifting during installation or use, which would cause inconvenience to the use of the lamp.

[0045] In some specific embodiments, reference Figure 6 and Figure 8 The light source positioning structure 11 includes a positioning ring 111, the positioning ring 111 matches the shape of the light source board 2, and the light source installation position 14 is located inside the positioning ring 111. The positioning ring 111 matches the shape of the light source board 2, which is conducive to improving the positioning speed of the light source board 2 on the lamp holder 1, thereby improving the installation efficiency of the light source board 2.

[0046] In some other embodiments, the light source positioning structure 11 includes a plurality of positioning blocks, and the plurality of positioning blocks are arranged in an orderly manner at intervals to enclose and form a light source installation position 14 .

[0047] In some specific embodiments, reference Figure 3 The lens 3 is provided with a plurality of first mounting holes 36, and the lamp holder 1 is provided with a plurality of second mounting holes 13, and the plurality of first mounting holes 36 and the plurality of second mounting holes 13 correspond to each other one by one. The chandelier structure further comprises a plurality of screws 37, and the screws 37 are passed through the corresponding first mounting holes 36 and second mounting holes 13 to mount the lens 3 on the lamp holder 1. The chandelier structure needs to be hung upside down when in use, and the lens 3 needs to bear the weight of the light source board 2. The lens 3 can be mounted on the lamp holder 1 more stably by the screws 37, so that the lens 3 and the light source board 2 are not easy to loosen, thereby improving the structural stability of the chandelier structure.

[0048] Specifically, a plurality of first mounting holes 36 are arranged along the edge of the lens 3, and a plurality of second mounting holes 13 are arranged along the edge of the lamp holder 1. The first mounting holes 36 include a first accommodating channel for accommodating the nut of the screw 37 and a second accommodating channel for accommodating the stud of the screw 37, so that after the screw 37 is screwed in, the nut of the screw 37 will not protrude from the lens 3, which is conducive to improving the aesthetics.

[0049] In some specific embodiments, reference Fig.10 An adhesive layer 6 is provided between the light source board 2 and the lamp holder 1 .

[0050] Specifically, the bonding layer 6 includes thermal conductive silicone grease, and the light source board 2 is bonded to the lamp holder 1 through the thermal conductive silicone grease, which is beneficial to improve the structural stability of the light source board 2 and the lamp holder 1. The light source board 2 is specifically an aluminum substrate, which is beneficial to cooperate with the thermal conductive silicone grease to improve the heat dissipation efficiency and ensure the normal operation of the chandelier structure.

[0051] In some specific embodiments, reference Figure 3 and Figure 5 The lens 3 is provided with a plurality of annular grooves 33, and the light source board 2 is provided with a plurality of lamp bead groups 22, the lamp bead groups 22 include a plurality of lamp beads 221, and the plurality of lamp beads 221 of the same lamp bead group 22 are arranged around the axis of the light source board 2 and are all located in the same annular groove 33, and the plurality of annular grooves 33 correspond to the plurality of lamp bead groups 22 one by one. The annular grooves 33 are provided to prevent the lamp beads 221 from being crushed, and at the same time, the matching relationship between the annular grooves 33 and the lamp bead groups 22 can be utilized to assist in positioning the light source board 2 on the lens 3, which is conducive to improving the installation efficiency of the light source board 2.

[0052] Specifically, a recessed portion 35 is provided on the lens 3. After the lens 3 is mounted on the lamp holder 1, the recessed portion 35 is pressed against the light source board 2, further improving the stability of the installation of the light source board 2. The annular groove 33 is provided on the recessed portion 35, and its opening faces the light source board 2. The provision of the annular groove 33 can protect the lamp bead group 22, so that the lamp bead 221 will not be damaged by pressure, and at the same time, the distance between the lens 3 and the lamp bead 221 is relatively close, which is conducive to enhancing the light transmission effect.

[0053] In some specific embodiments, reference Figures 1 to 3 The lens 3 is convexly formed with a ventilation groove 32, which has an opening toward the light source board 2. The lens 3 is also provided with a ventilation membrane 321, which blocks the opening of the ventilation groove 32, and a ventilation hole 322 is opened on the side wall of the ventilation groove 32. The ventilation groove 32 and the ventilation membrane 321 can balance the air pressure inside and outside the chandelier structure, avoiding deformation of parts due to thermal expansion and contraction, which affects the normal use of the chandelier structure.

[0054] Generally, in order to balance the internal and external air pressure of the chandelier structure, a vent valve installation hole is opened on the lamp holder 1, and then a vent valve is installed on the vent valve installation hole. However, such a setting is more troublesome and is not conducive to improving the assembly efficiency of the chandelier structure.

[0055] In this embodiment, a ventilation groove 32 integrally formed with the lens 3 is provided on the lens 3, and a ventilation membrane 321 is provided at the opening of the ventilation groove 32, and ventilation holes 322 are provided on the side walls of the ventilation groove 32, which can achieve the same function as the above-mentioned ventilation valve, but the structure is relatively simple, which is conducive to improving the assembly efficiency of the chandelier structure.

[0056] During production, after the lens 3 is formed, the gas permeable membrane 321 is bonded to the opening of the gas permeable groove 32 by using bonding material.

[0057] Due to the heat dissipation requirements, the lamp holder 1 is generally made of metal material, generally aluminum alloy. The lens 3 is generally made of plastic. During production, it is easier and less costly to integrally form the venting groove 32 on the lens 3 than to integrally form the venting groove 32 on the lamp holder 1. Therefore, setting the venting groove 32 on the lens 3 is more conducive to improving economic benefits.

[0058] In some specific embodiments, reference Figure 3 and Figure 8 A rubber ring mounting annular groove 34 is provided on the side of the lens 3 facing the lamp holder 1, in which a waterproof rubber ring 5 is provided. The positioning ring 111 on the lamp holder 1 presses the waterproof rubber ring 5 into the rubber ring mounting annular groove 34 to prevent liquid from entering the interior of the chandelier structure.

[0059] In some specific embodiments, reference Figure 1 A hanging ring 4 is provided on the side of the lamp holder 1 away from the light source board 2 .

[0060] A chandelier is one of many lamp structures, and different types of lamps are more or less interoperable in structure. If the conditions of use are met, part or all of the above chandelier structure can also be used as a component of other lamps, not just in chandeliers.

[0061] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
