[0054] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0055] like Figures 1 to 7As shown, the lamp provided by the embodiment of the present invention includes: a lampshade 50, a light-emitting member 60, a lamp connector 70 and a metal base 10; the lampshade 60 is installed on the metal base 10 to form a light-emitting cavity, and the light-emitting member 60 is located in the light-emitting cavity; the metal base 10 is provided with a central hole 11 and a plug hole 12, and the plug hole 12 is connected to the central hole 11; a first terminal 20 is provided in the plug hole 12, an insulating seat 80 is provided between the first terminal 20 and the plug hole 12, and a first terminal 20 is installed in the central hole 11. Two terminals 30, and the second terminal 30 is electrically insulated from the metal base 10, and the first terminal 20 and the second terminal 30 are electrically connected through the elastic conductive member 40, and the second terminal 30 is electrically connected to the light-emitting member 60; the lamp connector 70 includes a metal tube 71 and an electric wire arranged in the metal tube and insulated from the metal tube 71, at least one end of the metal tube is inserted into the plug hole 12 and is electrically connected to the metal base 10; at least one end of the electric wire is electrically connected to the first terminal 20.

[0056] Specifically, the metal base 10 is made of a metal material with excellent thermal conductivity and has a certain structural strength. The metal base 10 serves as another electrode of the lamp and is used to form a current loop. In this embodiment, the metal base 10 can be made of metal aluminum. The metal base 10 can be a solid of revolution or a triangular prism or a rectangular parallelepiped or a cube or a regular hexagonal column or a regular octagonal column. The metal base 10 has different structural shapes and provides different styles of lamps to meet customers' different needs for the design of lamps. In this embodiment, the shape of the metal base 10 is not limited, and the metal base 10 can be preferably designed as a solid of revolution.

[0057] A lampshade 50 is mounted on the metal base 10. The lampshade 50 can be made of a transparent plastic material, has a certain elasticity, and can be deformed under the extrusion of an external force, so that the lampshade 50 can be easily installed on the metal base 10. In this embodiment, the metal base 10 is provided with an annular skirt protruding from its end surface, and an annular boss engaged with the annular skirt is provided at the opening of the lampshade 50. The annular boss can be embedded in the annular skirt. To facilitate the connection between the lampshade 50 and the metal base 10, the annular boss of the lampshade 50 is provided with a plurality of notches. The notches provided in the lampshade 50 are used to absorb the deformation caused by the extrusion between the annular boss and the annular skirt, so that the lampshade can be extruded and installed on the metal base 10 and keep in close contact with the annular skirt of the metal base 10.

[0058] It can be understood that the lampshade 50 can also be installed on the metal base 10 by other connection forms. For example, the annular skirt of the lampshade 50 can be provided with an external thread, and the inner surface of the annular boss of the metal base 10 can be provided with an internal thread that matches the external thread of the annular skirt. The lampshade 50 is inserted into the metal base 10 and fixed by connecting the internal thread and the external thread. In addition, the annular skirt of the lampshade 50 can be provided with an internal thread, and the outer surface of the annular boss of the metal base 10 is provided with an external thread that matches the internal thread of the annular skirt. The lampshade 50 is sleeved on the annular boss of the metal base 10 and fixed by the internal thread and the external thread.

[0059] A light-emitting cavity is formed between the metal base 10 and the lampshade 50, in which a light-emitting component 60 is installed. In this embodiment, there is no limitation on the light-emitting component 60, which may be an incandescent lamp, a halogen tungsten lamp, a gas discharge lamp, etc. The light emitted by the light-emitting component is scattered around the lamp through the lampshade.

[0060] A central hole 11 is provided along the axial direction of the metal base 10, and a plurality of plug holes 12 are provided around the central hole 11 of the metal base 10, and one end of the plug hole 12 is connected to the outside, and the other end is through the central hole 11. A second terminal 30 is provided in the central hole 11, and the second terminal 30 is electrically insulated from the metal base 10, one end of the second terminal 30 is fixedly connected to the light emitting member 60, and an electrical connection is formed between the second terminal 30 and the light emitting member 60, and the light emitting member 60 is fixed on the metal base 10, so that the second terminal 30 is fixedly installed in the metal base 10.

[0061] A first terminal 20 is disposed in the plug hole 12, an insulating seat 80 is disposed between the first terminal 20 and the plug hole 12, and the first terminal 20 is electrically insulated from the metal base 10. An elastic conductive member 40 is disposed between the first terminal 20 and the second terminal 30, and the two ends of the elastic conductive member 40 are respectively abutted against the first terminal 20 and the second terminal 30 to achieve electrical connection between the first terminal 20 and the second terminal 30, and then the first terminal 20, the elastic conductive member 40, the second terminal 30 and the light-emitting member 60 form a conducting circuit. It can be understood that the light-emitting member 60 is provided with a positive access terminal and a negative access terminal, the positive access terminal can be electrically connected to the second terminal 30, and the negative access terminal can be electrically connected to the metal base 10.

[0062] The lamp connector 70 in this embodiment includes a metal tube and an electric wire. The electric wire is arranged inside the metal tube, and there is no conduction between the electric wire and the metal tube, forming electrical insulation; one end of the metal tube is inserted into the plug hole 12 and electrically connected to the metal base 10, and the other end of the metal tube can be inserted into the plug hole 12 of the adjacent metal base 10, or the other end of the metal tube can be electrically connected to the negative pole of the power supply. One end of the electric wire is electrically connected to the first terminal 20, and the other end of the electric wire can be connected to the first terminal 20 on the adjacent metal base 10, or the other end of the electric wire is electrically connected to the positive pole of the power supply.

[0063] It is understandable that in the above embodiment, the first terminal 20 is connected to the positive circuit and the metal base 10 is connected to the negative circuit only to facilitate the introduction of the current loop formed by the lamp, and does not limit the circuit connected to the first terminal 20 and the metal base 10.

[0064] The lamp provided in this embodiment has a metal base 10 with a plug hole 12, and a first terminal 20 is provided in the plug hole 12. The wire 72 of the lamp connector 70 is electrically connected to the first terminal 20, and the metal tube 71 of the lamp connector 70 is electrically connected to the metal base 10. In this way, electrical connection between multiple lamps can be completed without connecting the wires 72 and threading, thereby reducing the difficulty in the manual production of the lamp and avoiding damage to the lamp, while improving the safety of the lamp during use.

[0066] Specifically, lampshades 50 are provided at both ends of the metal base 10, that is, a first lampshade 51 is provided on the upper end surface of the metal base 10, and a second lampshade 52 is provided on the lower end surface of the metal base 10. A first light-emitting cavity is formed between the first lampshade 51 and the upper end surface of the metal base 10, and a first light-emitting component is provided in the first light-emitting cavity. A second light-emitting cavity is formed between the second lampshade 52 and the lower end surface of the metal base 10, and a second light-emitting component is provided in the second light-emitting cavity. It is understandable that the customer can choose to install only the first light-emitting component or the second light-emitting component on the metal base 10 according to the use requirements, or can install the first light-emitting component and the second light-emitting component on the metal base 10 at the same time, thereby meeting the customer's needs for different lighting effects; the lamp is provided with two light-emitting components 60 at the same time to improve the reliability of the lamp during use.

[0067] In this embodiment, the light-emitting component 60 includes a circuit board 61 and a plurality of light-emitting diodes arranged on the circuit board 61; a first through hole 63 and a second through hole 64 are arranged on the circuit board 61, and an annular conductive film 65 is arranged on the circuit board 61 around the first through hole 63, a screw is inserted into the first through hole 63, the cap end of the screw is pressed on the annular conductive film 65 around the first through hole 63, and the end of the screw rod is electrically connected to the second terminal 30; an annular conductive film 65 is arranged on the circuit board 61 around the second through hole 64, a screw is inserted into the second through hole 64, the cap end of the screw is pressed on the annular conductive film 65 around the second through hole 64, and the end of the screw rod is electrically connected to the metal base 10.

[0068] Specifically, the light-emitting component 60 includes a circuit board 61 on which a plurality of light-emitting diodes are arranged. The circuit board 61 is mounted on the end surface of the metal base 10 . By utilizing the heat dissipation performance of the metal base 10 , the heat generated on the circuit board 61 can be conducted to the outside through the metal base 10 .

[0069] A first through hole 63 is provided on the circuit board 61, and a circle of annular conductive film 65 is provided on the surface of the circuit board 61 located outside the first through hole 63.

[0070] A second through hole 64 is also provided on the circuit board 61. A circle of annular conductive film 65 is provided on the circuit board 61 located outside the second through hole 64.

A screw is inserted into the second through hole 64, and the cap end of the screw is pressed on the annular conductive film 65 around the second through hole 64 of the circuit board 61, that is, the cap end of the screw is electrically connected to the negative electrode access terminal of the circuit board 61, and the end of the screw rod is electrically connected to the metal base 10.

[0071] The positive access end of the circuit board 61 is electrically connected to the wires of the second terminal 30, the first terminal 20 and the lamp connector 70, and the negative access end of the circuit board is electrically connected to the metal base 10 and the metal tube of the lamp connector 70, so that the light-emitting diode forms a current loop, thereby lighting the light-emitting diode. In this embodiment, compared with the welding method of the circuit board 61, the metal base 10 and the second terminal 30 in the prior art, an annular conductive film 65 is provided on the circuit board 61, and is electrically connected to the second terminal 30 and the metal base 10 by screws, which simplifies the electrical connection between the circuit board 61, the metal base 10 and the second terminal 30.

[0072] In order to facilitate the electrical connection between the positive access end of the circuit board 61 and the second terminal 30, in this embodiment, a threaded hole for connecting a screw is provided at the end of the second terminal 30. Specifically, a threaded hole is provided on the end face of the second terminal 30 facing the circuit board 61, and an internal thread matching the external thread of the screw is provided in the threaded hole. The screw section of the screw passes through the first through hole 63 and is fixed in the threaded hole of the second terminal 30. The nut of the screw is crimped on the annular conductive film 65 provided around the first through hole 63, so as to realize the electrical connection between the positive access end of the circuit board 61 and the second terminal 30. In this embodiment, the screw is fixed in the threaded hole of the second terminal 30, so that the second terminal 30 and the circuit board 61 can form a stable electrical connection.

[0073] In this embodiment, a plurality of avoidance holes 66 are provided on the circuit board 61, and threaded holes corresponding to the avoidance holes 66 are respectively provided on the upper and lower end surfaces of the metal base 10, and the threaded holes penetrate into the plug-in holes 12; locking bolts are inserted into the avoidance holes 66 and the threaded holes, and the locking bolts abut against the insulating seat 80.

[0074] Specifically, a plurality of avoidance holes 66 are provided on the circuit board 61, and the avoidance holes 66 do not interfere with the first through hole 63, the second through hole 64 and the light-emitting diode 62. The upper end surface and the lower end surface of the metal base 10 are respectively provided with threaded holes corresponding to the avoidance holes 66, and one end of the threaded hole is connected to the plug hole 12, and an insulating seat 80 is arranged in the plug hole 12; a locking bolt is inserted in the avoidance hole 66, and the screw section of the locking bolt is fixedly connected in the threaded hole, and the circuit board 61 is fitted and installed on the upper end surface of the metal base 10 or the lower end surface of the metal base 10.

[0075] The ends of the screw sections of the locking bolts installed at both ends of the metal base 10 can extend out of the threaded holes respectively and abut against the insulating seat 80 located in the plug-in hole 12. The two sides of the insulating seat 80 are locked in the plug-in hole 12 under the clamping action of the locking bolts, preventing the insulating seat 80 from moving left and right and up and down in the plug-in hole 12.

[0076] In this embodiment, the insulating seat 80 is locked in the plug hole 12 by the locking bolt in the avoidance hole 66, and the circuit board 61 is also installed on the end surface of the metal base 10, which simplifies the installation and fastening of the circuit board 61.

The second terminal 30 and the first terminal 20 are electrically connected through the elastic conductive member 40, so that the second terminal 30 and the first terminal 20 are in an electrically connected state at any time, thereby enhancing the conductivity between the second terminal 30 and the first terminal 20.

[0078] On the basis of the above embodiment, a slot for inserting the elastic conductive member 40 is provided on the side wall of the second terminal 30; the slot is in clearance with the outer diameter of the elastic conductive member 40. A column for sleeve-fitting the elastic conductive member 40 is provided at the end of the first terminal 20 close to the second terminal 30.

[0079] Specifically, a slot is provided on the side wall of the second terminal 30, and the slot can be arranged around the side wall of the second terminal 30. The slot width of the slot matches the outer diameter clearance of the elastic conductive member 40, so that one end of the elastic conductive member 40 can be inserted into the slot and locked, and the other end of the elastic conductive member 40 can be sleeved on the first terminal 20; the elastic conductive member 40 can be effectively prevented from falling off or deviating from between the first terminal 20 and the second terminal 30, thereby ensuring that the first terminal 20 and the second terminal 30 form a stable electrical connection.

[0080] It is understandable that a column for connecting the elastic conductive member 40 may be provided at one end of the first terminal 20 close to the second terminal 30 , and the outer diameter of the column is loosely matched with the inner diameter of the elastic conductive member 40 , so that the elastic conductive member 40 is firmly installed on the first terminal 20 .

The insulating skin 722 is used to isolate the wire core 721 from the metal tube 71, so that the wire core 721 and the metal tube 71 are electrically insulated. To facilitate the electrical connection between the wire 72 and the first terminal 20, the parts of the wire core 721 protruding from the insulating skin 722 at both ends form a first wiring portion and a second wiring portion. The wire 72 can be electrically connected to the first terminal 20 located in the plug hole 12 through the first wiring portion or the second wiring portion.

[0090] On the basis of the above embodiment, the lamp connector 70 also includes a third terminal 73 and a fourth terminal 74, which are respectively plugged into the two ends of the metal tube 71; a first insulating sleeve 75 is arranged between the third terminal 73 and the metal tube 71, and the first wiring portion extends into the first insulating sleeve 75 and is electrically connected to the third terminal 73; a second insulating sleeve 76 is arranged between the fourth terminal 74 and the metal tube 71, and the second wiring portion extends into the second insulating sleeve 76 and is electrically connected to the fourth terminal 74.

[0092] Among them, the first wiring part of the wire core 721 extends into the first insulating sleeve 75 and is electrically connected to the third terminal 73. The first insulating sleeve 75 can wrap the insulating skin 722 at the first wiring part, so that the first wiring part, the third terminal 73 and the metal tube 71 are electrically insulated; the second wiring part of the wire core 721 extends into the second insulating sleeve 76 and is electrically connected to the fourth terminal 74. The second insulating sleeve 76 can wrap the insulating skin 722 at the second wiring part, so that the second wiring part, the fourth terminal 74 and the metal tube 71 are electrically insulated.

[0093] The third terminal 73 or the fourth terminal 74 in this embodiment is electrically connected to the first terminal 20 in the plug hole 12 of the metal base 10, which can facilitate the electrical connection between the lamp connector 70 and the metal base 10 and improve the efficiency of handmade lamps.

[0094] Based on the above embodiment, a sleeve joint 77 is provided at the end of the metal tube 71; the metal tube 71 is inserted into one end of the sleeve joint 77, and the other end of the sleeve joint 77 is provided with an external thread matching the internal thread of the plug-in hole 12; the sleeve joint 77 is connected to the plug-in hole 12 of the metal base 10 through the external thread and the internal thread.

[0095] Specifically, a sleeve joint 77 is sleeved on the end of the metal tube 71, and a threaded connection section is provided at the end of the sleeve joint 77 away from the metal tube 71. The threaded connection section is provided with an external thread that matches the internal thread of the plug-in hole 12. The metal tube 71 and the metal base 10 are fixedly installed on the metal base 10 through the sleeve joint 77 and an electrical connection is formed between the metal tube 71 and the metal base 10.

[0096] It can be understood that in order to prevent the metal tube 71 from falling off the sleeve joint 77, the outer surface of the tube wall of the metal tube 71 near the sleeve joint 77 is provided with an external thread, and the inner wall of the sleeve joint 77 near the end of the metal tube 71 is provided with an internal thread that cooperates with the external thread of the metal tube 71; the metal tube 71 and the sleeve joint 77 are connected together by the internal thread and the external thread, which effectively prevents the metal tube 71 from falling off from the sleeve joint 77.

[0097] In addition, the present embodiment also provides another way to enhance the connection reliability between the metal tube 71 and the sleeve joint 77; a limiting hole 771 is provided on the side wall of the sleeve joint 77, and a limiting groove 711 is provided on the tube wall of the metal tube 71. The limiting groove 711 can be annularly arranged on the tube wall surface of the metal tube 71, and a limiting bolt 78 is inserted into the limiting hole 771, and the limiting bolt 78 is snapped into the limiting groove 711; when the metal tube 71 is inserted into the sleeve joint 77, the limiting hole 771 is made to correspond to the limiting groove 711, and the limiting bolt 78 is inserted into the limiting hole 771, and the end part of the limiting bolt 78 is snapped into the limiting groove 711, which can effectively prevent the metal tube 71 from moving in the sleeve joint 77 along the axial direction of the sleeve joint 77.

[0098] It is understandable that in order to enhance the reliability of the connection between the metal tube 71 and the sleeve joint 77 , the metal tube 71 and the sleeve joint 77 can be threadedly connected while a limiting bolt 78 is installed between the metal tube 71 and the sleeve joint 77 for limiting.
