(27) Reference is made to FIG. 1 to FIG. 3, an embodiment of the present application provides the tree lamp 10, and the tree lamp 10 includes the lamp housing 100, a light-emitting body 200 and the base 300, where the lamp housing 100 is configured to have a tree shape, so that the lamp housing 100 can play a role in decoration; the light-emitting body 200 is provided on the lamp housing 100, and specifically, the light-emitting body 200 can be provided in an inner cavity of the lamp housing 100 or fixed to an outer surface of the lamp housing 100; and the lamp housing 100 is mounted on the base 300.

(28) FIG. 2 and FIG. 3 show that a mounting portion 110 and power connection contacts 120 are formed at a lower end of the lamp housing 100, the light-emitting body 200 is electrically connected to the power connection contacts 120, a mounting recess 310 is formed in a top surface of the base 300, electrically-conductive structures 313 are provided in the mounting recess 310, a power supply unit 320 is provided inside the base 300, and the electrically-conductive structures 313 are electrically connected to the power supply unit 320.

(30) The light-emitting body 200 is an object that can emit light when being electrified, for example, an incandescent lamp and an LED lamp. The light-emitting body 200 can be electrically connected to the power connection contacts 120 by means of wires 500.

(31) The power connection contacts 120 and the electrically-conductive structures 313 are made of conductors, and for cost considerations, the conductors can be relatively common metal conductors, for example, copper, aluminum and nickel.

(32) Reference is made to FIG. 4 to FIG. 9, FIG. 4 is a structural schematic diagram of a lamp housing in an embodiment, FIG. 5 is an enlarged view of area A of the lamp housing as shown in FIG. 4, FIG. 6 is a structural schematic diagram of a base in the embodiment as shown in FIG. 4, FIG. 7 is an enlarged view of area B of the base as shown in FIG. 6, FIG. 8 is a sectional view of a tree lamp in the embodiment as shown in FIG. 4, and FIG. 9 is an enlarged view of area C in the sectional view as shown in FIG. 8.

(33) In an embodiment, each of the electrically-conductive structures 313 includes the elastic member 400, and the elastic member 400 is provided on a bottom wall of the mounting recess 310 and is electrically connected to the power supply unit 320. FIG. 7 shows that the elastic members 400 are the electrically-conductive structures 313. It is understandable that in other embodiments, the elastic members 400 can serves as parts of the electrically-conductive structures 313, and a manufacturer can freely configure same according to requirements.

(34) There are two elastic members 400, the two elastic members 400 are arranged at intervals, and distances between the two elastic members 400 and the center of the mounting recess 310 are equal; and there are two power connection contacts 120, and the two power connection contacts 120 correspond to the elastic members 400 on a one-to-one basis.

(35) It is understandable that the elastic members 400 will accumulate elastic forces after being compressed and then will generate abutting forces to the mounting portion 110, so that providing the two elastic members 400 can improve the stress uniformity of the mounting portion 110, and can make the connection between the mounting portion 110 and the base 300 more stable. In addition, compared with providing only one elastic member 400 to be electrically connected to the power connection contacts 120, providing the two elastic members 400 to be correspondingly connected to the two power connection contacts 120 on a one-to-one basis can reduce the impedance, thereby reducing the energy consumption of the tree lamp 10.

(36) Specifically, the lamp housing 100 can be made of a resin material, for example, thermosetting resin, so that the lamp housing 100 has the good hardness and the good high-temperature resistance, and is free from the phenomenon of melting due to heating. FIG. 1 shows that the lamp housing 100 can be provided with a plurality of simulated branches 130, so that the lamp housing 100 is similar to a tree in shape.

(37) Specifically, reference is continuously made to FIG. 2 and FIG. 3, the mounting portion 110 is detachably connected in the mounting recess 310, so that the lamp housing 100 can be separated from the base 300; and when the lamp housing 100 is separated from the base 300, the power connection contacts 120 are also separated from the electrically-conductive structures 313, so that the lamp housing 100 and the base 300 can be completely separated without being restrained by the wires 500, and separate maintenance of the lamp housing 100 or the base 300 is facilitated.

(38) Specifically, the mounting portion 110 can be detachably connected in the mounting recess 310 in a manner such as threaded connection, magnetically attracted connection, interference fit and snap-fitting. Of course, in some other embodiments, the lamp housing 100 can be connected to the base 300 in a nondetachable manner such as gluing or welding.

(39) In an embodiment, reference is made to FIG. 4 to FIG. 9, first protrusions 311 are formed on an inner wall of the mounting recess 310, and limiting grooves 111 fitted with the first protrusions 311 are formed in an outer wall of the mounting portion 110. FIG. 8 and FIG. 9 show that the mounting portion 110 can be inserted into the mounting recess 310, and at least parts of the first protrusions 311 are embedded in the limiting grooves 111 to limit a housing to be separated from the base 300. When the lamp housing 100 needs to be detached from the base 300, a user can hold the lamp housing 100 to use a greater force to pull the mounting portion 110 out of the mounting recess 310, thereby separating the lamp housing 100 from the base 300. It is understandable that in other embodiments, positions of the first protrusions 311 and positions of the limiting grooves 111 can be exchanged, that is, the first protrusions 311 are provided on the outer wall of the mounting portion 110, and the corresponding limiting grooves 111 are provided in the inner wall of the mounting recess 310.

(40) Specifically, there are two first protrusions 311, and the two first protrusions 311 are respectively located on two opposite sides of the mounting portion 110; and there are two limiting grooves 111, and the two limiting grooves 111 correspond to the two first protrusions 311 on a one-to-one basis.

(41) Reference is made to FIG. 10 to FIG. 15, FIG. 10 is a structural schematic diagram of a lamp housing in another embodiment of the present application, FIG. 11 is an enlarged view of area D of the lamp housing as shown in FIG. 10, FIG. 12 is a structural schematic diagram of a base in the embodiment as shown in FIG. 10, FIG. 13 is an enlarged view of area E of the base as shown in FIG. 12, FIG. 14 is a sectional view of a tree lamp in the embodiment as shown in FIG. 10, and FIG. 15 is an enlarged view of area F in the sectional view as shown in FIG. 14.

(42) In another embodiment, snap-fitting grooves 112 are formed in the outer wall of the mounting portion 110, and snap-fitting blocks 312 fitted with the snap-fitting grooves 112 are formed in the inner wall of the mounting recess 310. FIG. 14 and FIG. 15 show that the mounting portion 110 is capable of being inserted into the mounting recess 310, and at least parts of the snap-fitting blocks 312 are embedded in the snap-fitting grooves 112. It is understandable that in other embodiments, positions of the snap-fitting blocks 312 and positions of the snap-fitting grooves 112 can be exchanged, that is, the snap-fitting grooves 112 are provided in the inner wall of the mounting recess 110, and the corresponding snap-fitting blocks 312 are provided on the outer wall of the mounting portion 310.

(43) Specifically, there are two snap-fitting blocks 312, and the two snap-fitting blocks 312 are respectively located on two opposite sides of the mounting recess 310; and there are two snap-fitting grooves 112, and the two snap-fitting blocks 312 correspond to the two snap-fitting grooves 112 on a one-to-one basis. The snap-fitting blocks 312 are provided on inner walls of the two opposite sides of the mounting recess 310 at the same time, so that the stress stability of the mounting portion 110 can be improved, the connection between the mounting portion 110 and the mounting recess 310 can be firmer, and loosening caused by warping of one side of the mounting portion 110 can be avoided.

(44) Further, FIG. 15 shows that each of the snap-fitting blocks 312 includes a fixed end 3121 and a rotating end 3122 which are opposite to each other, and the fixed end 3121 is connected to the inner wall of the mounting recess 310; and the base 300 is provided with avoiding spaces 330 for the snap-fitting blocks 312 to rotate, and each of the avoiding spaces 330 is located on one side of the snap-fitting block 312 away from the mounting recess 310. In a process of mounting the mounting portion 110 in the mounting recess 310, the bottom of the mounting portion 110 extrudes the rotating ends 3122 to enable the rotating ends 3122 to be elastically deformed and rotate in a direction away from the mounting portion 110, the mounting portion 110 is continuously inserted into the mounting recess 310 until the rotating ends 3122 are aligned to the snap-fitting grooves 112, and at least parts of the rotating ends 3122 are embedded in the snap-fitting grooves 112.

(45) Reference is made to FIG. 16, the lamp housing 100 includes a housing body 101, the mounting portion 110 is provided at a lower end of the housing body 101, and the power connection contacts 120 are provided in an inner cavity of the mounting portion 110. It is understandable that in some embodiments, the power connection contacts 120 can be provided at other positions of the housing body 101 instead of being provided on the mounting portion 110.

(46) Reference is made to FIG. 16 to FIG. 18, in an embodiment, each of the power connection contacts 120 includes contact pins 121 and the elastic member 400, one end of each of the contact pins 121 is exposed out of the mounting portion 110, and two opposite ends of the elastic member 400 are respectively connected to the contact pins 121 and the mounting portion 110. In the process of mounting the mounting portion 110 in the mounting recess 310, the contact pins 121 are in contact with the electrically-conductive structures 313, then the mounting portion 110 is continuously inserted into the mounting recess 310, the elastic members 400 in the power connection contacts 120 are compressed and accumulate elastic forces, and finally, the mounting portion 110 is fixed in the mounting recess 310.

(47) Specifically, there are two contact pins 121, one of the two contact pins 121 is located at the center of the mounting portion 110, and the other one deviates from the center of the mounting portion 110. FIG. 18 shows that each of the electrically-conductive structure 313 includes a first electrically-conductive sheet 3131 and a second electrically-conductive sheet 3132, the first electrically-conductive sheet 3131 and the second electrically-conductive sheet 3132 are configured to be in contact with the different contact pins 121, the first electrically-conductive sheet 3131 is a round electrically-conductive sheet, the second electrically-conductive sheet 3132 is an annular electrically-conductive sheet and surrounds the first electrically-conductive sheet 3131, and there is a gap between the first electrically-conductive sheet 3131 and the second electrically-conductive sheet 3132.

(48) It is understandable that compared with providing only one contact pin 121 to be in contact with one electrically-conductive sheet, providing the two contact pins 121 to be in corresponding contact with the two electrically-conductive sheets on a one-to-one basis can reduce the impedance, thereby reducing the energy consumption of the tree lamp 10.

(49) In addition, the first electrically-conductive sheet 3131 and the second electrically-conductive sheet 3132 are the round electrically-conductive sheet and the annular electrically-conductive sheet respectively, so that in the process of rotating the mounting portion 110 relative to the mounting recess 310, the contact pins 121 and the corresponding electrically-conductive sheets can always be kept opposite each other up and down without staggering, and the contact relationship between the contact pins 121 and the corresponding electrically-conductive sheets will not be affected by the rotation angle of the mounting portion 110. The first electrically-conductive sheet 3131 is round, so that the area of the first electrically-conductive sheet 3131 can be set relatively small, which is more beneficial to reasonable arrangement of the electrically-conductive sheet in a limited space.

(50) Specifically, the mounting portion 110 is of a sleeve structure 113, and the sleeve structure 113 is detachably sleeved at the lower end of the housing body 101. The light-emitting body 200 needs to be electrically connected to the power connection contacts 120 by means of the wires 500 or other electrically-conductive manners, and during assembly of the lamp housing 100, the power connection contacts 120 need to be connected to the wires 500, so that the mounting portion 110 is configured to be detachably connected to the housing body 101, the wires 500 can be relatively easily connected, and the assembly is facilitated. In addition, the power connection contact 120 or the light-emitting body 200 is convenient to maintain or replace when being damaged. The sleeve structure 113 can be detachably connected to the lower end of the housing body 101 in a manner such as snap-fitting or threaded connection.

(51) Further, the sleeve structure 113 includes a sleeve body 1131 and a sleeve cover 1132, the sleeve cover 1132 is detachably connected to the sleeve body 1131, the sleeve cover 1132 and the sleeve body 1131 enclose the inner cavity of the mounting portion 110, and the contact pins 121 and the elastic members 400 are provided in the inner cavity of the mounting portion 110. The sleeve cover 1132 and the sleeve body 1131 are detachable, so that the power connection contacts 120 are more convenient to assemble and maintain. The sleeve body 1131 can be detachably connected to the sleeve cover 1132 in a manner such as snap-fitting or threaded connection.

(52) In an embodiment, reference is made to FIG. 11 and FIG. 13, the outer wall of the mounting portion 110 is provided with a second protrusion 114, a guide groove 314 fitted with the second protrusion 114 is formed in the inner wall of the mounting recess 310, and an opening of the guide groove 314 is in communication with the top surface of the base 300. In the process of mounting the mounting portion 110 in the mounting recess 310, the second protrusion 114 is first aligned to the guide groove 314, and then the second protrusion 114 is inserted into the guide groove 314 along the opening of the guide groove 314, thereby driving the mounting portion 110 to enter the mounting recess 310.

(53) Specifically, there are one second protrusion 114 and one guide groove 314. That is, only when the second protrusion 114 is aligned to the guide groove 314, the mounting portion 110 can be inserted into the mounting recess 310, when the mounting portion 110 is mounted reversely, the second protrusion 114 and the guide groove 314 are respectively located on the two opposite sides of the mounting portion 110, the second protrusion 114 cannot be aligned to the guide groove 314, and then the mounting portion 110 cannot be inserted into the mounting recess 310. Therefore, the mounting portion 110 can only be mounted in the mounting recess 310 in a specific direction (that is, an extension direction of the guide groove 314), thereby avoiding a wrong mounting direction when the lamp housing 100 is mounted on the base 300.

(54) In an embodiment, reference is made to FIG. 5 and FIG. 9, cambered surfaces 115 are formed at the bottom of the mounting portion 110, an acute angle is formed between a tangent of each of the cambered surfaces 115 and an axis of the mounting portion 110, and a distance between each of the cambered surfaces 115 and the axis of the mounting portion 110 gradually decreases in a mounting direction of the mounting portion 110. In the process of mounting the mounting portion 110 in the mounting recess 310, the cambered surfaces 115 play a role in guiding the bottom of the mounting portion 110 to enter the mounting recess 310. It is understandable that the mounting direction of the mounting portion 110 refers to a direction in which the mounting portion 110 enters the mounting recess 310 from an opening of the mounting recess 310.

(55) Specifically, there are two cambered surfaces 115, the two cambered surfaces 115 are respectively located on two opposite sides of the mounting portion 110, and providing the cambered surfaces 115 on the two sides is more beneficial to mounting of the mounting portion 110. It is understandable that in other embodiments, the manufacturer can set the cambered surfaces 115 in other numbers or set no cambered surfaces 115 according to requirements.
