Description

Technical Field

[0001] The present application relates to the technical field of decorative lamps, and in particular to a tree-shaped decorative lamp. Background Art

[0002] Tree-shaped decorative lights are decorative lights that imitate the shape of a tree. They can provide lighting and have strong ornamental value. Therefore, tree-shaped decorative lights can be widely used in various scenes such as squares, courtyards, hotel lobbies, living rooms or bedrooms.

[0003] The tree-shaped decorative lamp in the related art includes a lamp housing at the top and a base at the bottom. The lamp housing and the base at the bottom are constrained by the wire, and it is difficult to completely separate the lamp housing and the base at the bottom. When the base needs to be repaired separately, it is inconvenient. Summary of the invention

[0004] The present application provides a tree-shaped decorative lamp, which aims to improve the convenience of repairing the base separately.

[0005] The specific technical solutions are as follows:

[0006] An embodiment of the present application provides a tree-shaped decorative lamp, which includes a lamp housing, a light-emitting body and a base. The lamp housing is constructed to have a tree shape, a housing is provided with a receiving cavity inside the lamp housing, a mounting portion is formed at the lower end of the lamp housing, and a power contact is also provided at the lower end of the lamp housing; the light-emitting body is provided in the housing cavity, and the light-emitting body is electrically connected to the power contact; a power supply unit is provided inside the base, a mounting groove is formed on the top surface of the base, a conductive structure is provided in the mounting groove, and the conductive structure is electrically connected to the power supply unit; wherein the mounting portion is detachably mounted in the mounting groove, and when the mounting portion is mounted in the mounting groove, the power contact is in contact with the conductive structure.

[0007] In the tree-shaped decorative lamp in the embodiment of the present application, a mounting portion is formed at the lower end of the lamp housing, a mounting groove is formed on the top surface of the base, and the mounting portion is detachably mounted in the mounting groove, so that the lamp housing can be separated from the base. In addition, a conductive structure is arranged in the mounting groove, and the conductive structure is electrically connected to the power supply unit. An electrical contact is arranged at the lower end of the lamp housing, and the electrical contact is electrically connected to the light-emitting body located inside the lamp housing. When the mounting portion is installed in the mounting groove, the electrical contact contacts the conductive structure, so that when the lamp housing is connected to the base, electrical conduction is achieved between the light-emitting body and the power supply unit through the electrical contact, the conductive structure, etc., and the power supply unit can provide electrical energy to the light-emitting body. When the lamp housing is separated from the base, the electrical contact is also separated from the conductive structure, so that the lamp housing and the base can be completely separated without being constrained, thereby improving the convenience of repairing the base alone.

[0008] In some embodiments, the mounting portion is a columnar structure, the mounting groove is a circular groove, and the mounting portion can be connected to the base by rotating relative to the mounting groove.

[0009] By rotating the mounting portion relative to the base, the lamp housing and the base can be connected and separated, and the installation and removal process is easy to operate, saving time and effort.

[0010] In some embodiments, the side wall of the mounting portion is formed with an external thread; the inner wall of the mounting groove is formed with an internal thread, and the internal thread is adapted to the external thread so that the mounting portion can be connected to the base by threaded matching.

[0011] The process of connecting the lamp housing and the base is to make the mounting part contact with the mounting groove, rotate the lamp housing, and the lamp housing drives the mounting part to rotate. Under the cooperation of the external thread and the internal thread, the mounting part and the mounting groove are tightly connected together. When the lamp housing needs to be separated from the base, it only needs to rotate the lamp housing in the opposite direction, and the mounting part will be loosened relative to the mounting groove.

[0012] In some embodiments, the power contact is arranged at the bottom of the mounting portion, the number of the power contacts is two, and the distances between the two power contacts and the center of the columnar structure are not equal; the conductive structure includes a first conductive sheet and a second conductive sheet, the first conductive sheet and the second conductive sheet are located on the bottom wall of the mounting groove, and the first conductive sheet and the second conductive sheet are used to contact different power contacts; the first conductive sheet is a circular conductive sheet, the second conductive sheet is an annular conductive sheet and surrounds the first conductive sheet, and there is a gap between the first conductive sheet and the second conductive sheet.

[0013] There are two power contacts, which are used to contact the first conductive sheet and the second conductive sheet respectively. Compared with the method of setting only one power contact, such a setting is conducive to reducing impedance, thereby reducing the energy consumption of the tree-shaped decorative lamp. In addition, the distances between the two power contacts and the center of the columnar structure are not equal. The first conductive sheet and the second conductive sheet are respectively a circular conductive sheet and an annular conductive sheet. In this way, during the rotation of the mounting portion relative to the mounting groove, the power contacts and the corresponding conductive sheets can always be relative to each other up and down without misalignment. In this way, the contact relationship between the power contacts and the corresponding conductive sheets will not be affected by the rotation angle of the mounting portion.

[0014] In some embodiments, one of the two power contacts is located at the center of the columnar structure, and the other of the two power contacts is offset from the center of the columnar structure; or, both of the two power contacts are offset from the center of the columnar structure.

[0015] In some embodiments, the mounting portion is a sleeve structure; a plug-in column is provided in the mounting groove, and the sleeve structure can be inserted into the mounting groove and sleeved on the plug-in column.

[0016] The mounting portion is connected to the base by plugging. Compared with the rotational connection of the mounting portion, the plugging method is simpler in operation and is conducive to improving the assembly or disassembly efficiency between the lamp housing and the base.

[0017] In some embodiments, the power contact is arranged inside the sleeve structure; the plug-in column is a hollow structure, the conductive structure is located inside the plug-in column, and a through hole is provided on the upper surface of the plug-in column, and the power contact can be inserted into the through hole and contact the conductive structure.

[0018] When the mounting portion is mounted in the mounting groove, the electrical contact can be in contact with the conductive structure, thereby enabling electrical conduction between the power supply unit and the light-emitting body.

[0019] In some embodiments, the conductive structure is a cylindrical structure, the upper end of the cylindrical structure is connected to the top wall of the plug-in column, and the power contact can extend into the cylindrical structure and contact the cylindrical structure. When the power contact is inserted into the through hole, the part of the power contact extending into the interior of the plug-in column will enter the cylindrical structure and contact the inner wall of the cylindrical structure. This contact method can make the power contact and the conductive structure have a relatively large contact area, which is conducive to ensuring the stability of the electrical conductor between the two.

[0020] In some embodiments, the number of the power contacts is two, the number of the conductive structures is two, and the number of the through holes is two. The two power contacts can be respectively inserted into corresponding through holes and contact the corresponding conductive structures.

[0021] There are two power contacts, each of which is used to contact a corresponding conductive structure. Compared with a method of only providing one power contact, such a configuration is conducive to reducing impedance, thereby reducing the energy consumption of the tree-shaped decorative lamp.

[0022] In some embodiments, the inner wall surface of the sleeve structure includes at least one first planar portion, and the outer wall surface of the plug-in column includes at least one second planar portion, the number of the second planar portions is equal to the number of the first planar portions, and the second planar portions are used to contact the first planar portions to limit the rotation of the sleeve structure relative to the plug-in column.

[0023] Such arrangement, on the one hand, helps to quickly find the angle for aligning the electrical contact with the through hole when the sleeve structure is sleeved on the plug-in post, and on the other hand, after the sleeve structure is connected to the plug-in post, it can prevent the sleeve structure from rotating relative to the plug-in post and causing damage to the electrical contact.

[0024] In some embodiments, the outer wall surface of the sleeve structure includes at least one third planar portion, and the inner wall surface of the mounting groove includes at least one fourth planar portion, the number of the fourth planar portions is equal to the number of the third planar portions, and the fourth planar portions are used to contact the third planar portions to limit the rotation of the sleeve structure relative to the mounting groove.

[0025] Such arrangement, on the one hand, helps to quickly find the angle for aligning the power contact with the through hole when the sleeve structure is inserted into the installation slot, and on the other hand, after the sleeve structure is inserted into the installation slot, it can prevent the sleeve structure from rotating relative to the installation slot and causing damage to the power contact.

[0026] In some embodiments, the power supply unit includes a battery and a circuit board, and the conductive structure and the battery are both electrically connected to the circuit board.

[0027] In some embodiments, the tree-shaped decorative lamp further includes a control switch, the control switch is electrically connected to the circuit board, and the control switch is connected to the circuit where the conductive structure and the battery are located to control the conduction or disconnection of the circuit.

[0028] In some embodiments, the base includes an upper shell and a lower cover plate, the lower cover plate is detachably connected to the upper shell, the upper shell and the lower cover plate jointly define an installation cavity, and the power supply unit is located in the installation cavity.

[0061] As mentioned in the background technology section, the tree-shaped decorative lamp in the related art includes a lamp housing at the top and a base at the bottom. An LED lamp is arranged in the lamp housing, and a power supply unit is arranged in the base. The LED lamp is electrically connected to the power supply unit through a wire. This makes it difficult to completely separate the lamp housing at the top and the base at the bottom. Even if the lamp housing and the base are separated, the two are still constrained by the wire. In this way, when the base needs to be repaired separately, it will be inconvenient.

[0062] Based on this, an embodiment of the present application provides a tree-shaped decorative lamp, which aims to improve the convenience of repairing the base separately.

[0063] like Figures 1 to 6 As shown, the tree-shaped decorative lamp 10 in the embodiment of the present application includes a lamp housing 100, a light-emitting body 200 and a base 300. The lamp housing 100 is constructed to have a tree shape. A receiving cavity is provided inside the lamp housing 100. A mounting portion 110 is formed at the lower end of the lamp housing 100. An electrical contact 120 is also provided at the lower end of the lamp housing 100. The light-emitting body 200 is provided in the receiving cavity, and the light-emitting body 200 is electrically connected to the electrical contact 120. A power supply unit 400 is provided inside the base 300. A mounting groove 301 is formed on the top surface of the base 300. A conductive structure 310 is provided in the mounting groove 301, and the conductive structure 310 is electrically connected to the power supply unit 400. The mounting portion 110 is detachably mounted in the mounting groove 301. When the mounting portion 110 is mounted in the mounting groove 301, the electrical contact 120 contacts the conductive structure 310.

[0064] Specifically, the lamp housing 100 can be made of a resin material, such as a thermosetting resin, so that the lamp housing 100 not only has good hardness, but also has good high temperature resistance and will not melt due to heat. A plurality of simulated branches 150 can be arranged on the lamp housing 100 so that the lamp housing 100 resembles a tree in shape. Figure 7 The lamp housing 100 may include a first shell 102 and a second shell 103 connected to each other. The first shell 102 and the second shell 103 may be manufactured and formed separately. Before connecting the first shell 102 and the second shell 103, the light emitting body 200 may be assembled with the first shell 102 or the second shell 103, and then the first shell 102 and the second shell 103 may be connected together by screw connection, glue bonding, etc.

[0065] The luminous body 200 is an object that can emit light when powered on, such as an incandescent lamp, an LED lamp, etc. The luminous body 200 can be electrically connected to the electrical contact 120 through a wire.

[0066] The conductive structure 310 is made of a conductor. For cost considerations, the conductor can be a common metal conductor, such as copper, aluminum, nickel, etc. The power supply unit 400 is used to provide power to the light emitting body 200. For example, please refer to Figure 6 The power supply unit 400 may include a battery 410 and a circuit board 420, and the conductive structure 310 and the battery 410 are both electrically connected to the circuit board 420, or the power supply unit 400 is a power board with a power cord.

[0067] In the tree-shaped decorative lamp 10 in the embodiment of the present application, a mounting portion 110 is formed at the lower end of the lamp housing 100, and a mounting groove 301 is formed on the top surface of the base 300. The mounting portion 110 is detachably mounted in the mounting groove 301, so that the lamp housing 100 can be separated from the base 300. In addition, a conductive structure 310 is arranged in the mounting groove 301, and the conductive structure 310 is electrically connected to the power supply unit 400. An electrical contact 120 is arranged at the lower end of the lamp housing 100, and the electrical contact 120 is electrically connected to the light-emitting body 200 located inside the lamp housing 100. When the mounting portion 110 is installed in the mounting groove 301, the electrical contact 120 contacts the conductive structure 310, so that when the lamp housing 100 is connected to the base 300, the light-emitting body 200 and the power supply unit 400 are electrically connected through the electrical contact 120, the conductive structure 310, etc., and the power supply unit 400 can provide electrical energy to the light-emitting body 200. When the lamp housing 100 is separated from the base 300 , the electrical contact 120 is also separated from the conductive structure 310 , so that the lamp housing 100 and the base 300 can be completely separated without being constrained, thereby improving the convenience of separate maintenance of the base 300 .

[0068] In some embodiments, Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the mounting portion 110 is a columnar structure 110a, the mounting groove 301 is a circular groove, and the mounting portion 110 can be connected to the base 300 by rotating relative to the mounting groove 301. It can be understood that the mounting portion 110 and the base 300 are also disassembled by rotating the mounting portion 110 relative to the mounting groove 301. By rotating the mounting portion 110 relative to the base 300, the connection and disassembly between the lamp housing 100 and the base 300 can be achieved, and the installation and disassembly process is easy to operate, which is relatively time-saving and labor-saving.

[0069] In one embodiment, please refer to Figure 3 and Figure 5 , the side wall of the mounting portion 110 is formed with an external thread 1101, and the inner wall of the mounting groove 301 is formed with an internal thread 3011, and the internal thread 3011 is adapted to the external thread 1101, so that the mounting portion 110 can be connected to the base 300 by threaded matching. The connection process between the lamp housing 100 and the base 300 is to make the mounting portion 110 contact with the mounting groove 301, rotate the lamp housing 100, and the lamp housing 100 drives the mounting portion 110 to rotate. Under the cooperation of the external thread 1101 and the internal thread 3011, the mounting portion 110 is fastened to the mounting groove 301. When it is necessary to separate the lamp housing 100 from the base 300, it is only necessary to rotate the lamp housing 100 in the opposite direction, and the mounting portion 110 will be loosened relative to the mounting groove 301.

[0070] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The electrical contact 120 is disposed at the bottom of the mounting portion 110. There are two electrical contacts 120. The distances between the two electrical contacts 120 and the center of the columnar structure 110a are not equal. The conductive structure 310 includes a first conductive sheet 311 and a second conductive sheet 312. The first conductive sheet 311 and the second conductive sheet 312 are located on the bottom wall of the mounting groove 301. The first conductive sheet 311 and the second conductive sheet 312 are used to contact different electrical contacts 120. The first conductive sheet 311 is a circular conductive sheet, and the second conductive sheet 312 is an annular conductive sheet that surrounds the first conductive sheet 311. There is a gap between the first conductive sheet 311 and the second conductive sheet 312.

[0071] In this embodiment, the power contact 120 is located at the bottom of the mounting portion 110, that is, the power contact 120 is exposed from the mounting portion 110. On this basis, the number of the power contact 120 is two, and the two power contacts 120 are used to contact the first conductive sheet 311 and the second conductive sheet 312 respectively. Compared with the method of only providing one power contact 120, such a configuration is conducive to reducing impedance, thereby reducing the energy consumption of the tree-shaped decorative lamp 10.

[0072] In addition, the distances between the two power contacts 120 and the center of the columnar structure 110a are not equal, wherein the power contact 120 with a smaller distance from the center of the columnar structure 110a is configured to contact the first conductive sheet 311, and the power contact 120 with a larger distance from the center of the columnar structure 110a is configured to contact the second conductive sheet 312. Since the first conductive sheet 311 and the second conductive sheet 312 are circular conductive sheets and annular conductive sheets, respectively, during the rotation of the mounting portion 110 relative to the mounting groove 301, the power contact 120 and the corresponding conductive sheet can always be opposite to each other up and down without misalignment, so that the contact relationship between the power contact 120 and the corresponding conductive sheet will not be affected by the rotation angle of the mounting portion 110.

[0073] Further, one of the two power contacts 120 may be located at the center of the columnar structure 110a, and the other of the two power contacts 120 may be offset from the center of the columnar structure 110a. Alternatively, both power contacts 120 may be offset from the center of the columnar structure 110a. If one of the power contacts 120 is located at the center of the columnar structure 110a, the area of ​​the first conductive sheet 311 may be set relatively small. If both of the power contacts 120 are offset from the center of the columnar structure 110a, the area of ​​the first conductive sheet 311 needs to be set relatively large so that in the horizontal direction, the area of ​​the first conductive sheet 311 can cover the position of one of the power contacts 120.

[0074] In some embodiments, Figures 8 to 15 As shown, the mounting portion 110 is a sleeve structure 110b, and a plug-in column 3014 is provided in the mounting groove 301. The sleeve structure 110b can be inserted into the mounting groove 301 and sleeved on the plug-in column 3014. In this embodiment, the mounting portion 110 and the base 300 are connected by plugging. Specifically, the sleeve structure 110b can be inserted into the mounting groove 301 and sleeved on the plug-in column 3014, and the connection between the mounting portion 110 and the base 300 is completed. Compared with the rotation connection method of the mounting portion 110, the plug-in method is simpler in operation, which is conducive to improving the assembly or disassembly efficiency between the lamp housing 100 and the base 300.

[0075] For further information, please refer to Fig. 9 and Fig.13 The electrical contact 120 is arranged inside the sleeve structure 110b, the plug post 3014 is a hollow structure, the conductive structure 310 is located inside the plug post 3014, and the upper surface of the plug post 3014 is provided with a through hole 3015, and the electrical contact 120 can be inserted into the through hole 3015 and contact the conductive structure 310. In this way, when the mounting portion 110 is mounted in the mounting groove 301, the electrical contact 120 can contact the conductive structure 310, so that the power supply unit 400 and the light-emitting body 200 are electrically connected.

[0076] Specifically, Fig.16 As shown, the conductive structure 310 can be a cylindrical structure 314, the upper end of the cylindrical structure 314 is connected to the top wall of the plug-in column 3014, and the power contact 120 can extend into the cylindrical structure 314 and contact the cylindrical structure 314. The cylindrical structure 314 can be made of a conductive material (such as a metal material). When the power contact 120 is inserted into the through hole 3015, the part of the power contact 120 extending into the interior of the plug-in column 3014 will enter the cylindrical structure 314 and contact the inner wall of the cylindrical structure 314. This contact method can make the power contact 120 and the conductive structure 310 have a relatively large contact area, which is conducive to ensuring the stability of the electrical conductor between the two.

[0077] In one embodiment, please refer to Fig. 9 , Fig.13 as well as Fig.16 , the number of the electrical contacts 120 is two, the number of the conductive structures 310 is two, the number of the through holes 3015 is two, and the two electrical contacts 120 can be respectively inserted into the corresponding through holes 3015 and contact the corresponding conductive structures 310. In this embodiment, the number of the electrical contacts 120 is two, and the two electrical contacts 120 are respectively used to contact a corresponding conductive structure 310. Compared with the method of only providing one electrical contact 120, such a configuration is conducive to reducing impedance, thereby reducing the energy consumption of the tree-shaped decorative lamp 10.

[0078] In one embodiment, please refer to Figure 8 , Fig. 9 , Fig.12 as well as Fig.13The inner wall surface of the sleeve structure 110b includes at least one first plane portion 1104, and the outer wall surface of the plug-in column 3014 includes at least one second plane portion 3016. The number of the second plane portions 3016 is equal to the number of the first plane portions 1104. The second plane portions 3016 are used to contact the first plane portions 1104 to limit the rotation of the sleeve structure 110b relative to the plug-in column 3014. In this embodiment, when the first plane portion 1104 and the second plane portion 3016 are attached to each other, the two electrical contacts 120 can be aligned with the two through holes 3015, and the first plane portion 1104 and the second plane portion 3016 can limit the rotation of the sleeve structure 110b relative to the plug-in column 3014 through the counteraction. With such a configuration, on the one hand, when the sleeve structure 110b is sleeved on the plug-in post 3014, it is helpful to quickly find the angle for aligning the power contact 120 with the through hole 3015. On the other hand, after the sleeve structure 110b is connected to the plug-in post 3014, it can prevent the sleeve structure 110b from rotating relative to the plug-in post 3014 and causing damage to the power contact 120.
