Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and in particular to a floor lamp. Background Technology

[0002] Floor lamps are a type of lighting fixture commonly used for illumination and creating ambiance, and they have a wide range of applications in daily life.

[0003] Floor lamps typically consist of a lamp post and a base, with one end of the post connected to the base. The base acts as a counterweight. The relatively heavy base lowers the floor lamp's center of gravity, reducing the risk of it tipping over.

[0004] Although the lamp post is relatively lightweight, it is much longer than the lamp base. In addition, most of the weight of the floor lamp is concentrated in the lamp base, making floor lamps difficult to package, transport, and store, resulting in higher logistics costs. Utility Model Content

[0005] The inventors of this application recognized that floor lamps in the related art, due to their large overall length and uneven weight distribution, with most of the weight concentrated at the lamp base, are inconvenient to package, transport, and store, ultimately leading to high logistics costs. The purpose of this application is to provide a floor lamp that solves the problem of high logistics costs caused by the large overall length and uneven weight distribution of floor lamps.

[0006] The basic concept proposed by the inventors of this application is to adopt a split design, in which the lamp pole and lamp holder of the floor lamp are detachably connected, so that the lamp pole and lamp holder can be packaged, transported and stored separately, reducing logistics costs, and then connected together when in use.

[0007] This application embodiment provides a floor lamp, the technical solution of which is as follows: The floor lamp includes:

[0008] Lamp holder; lamp pole, one end of which has a detachable connection with the lamp holder;

[0009] The end of the lamp post has a first connecting structure, and the lamp holder has a second connecting structure. The end of the lamp post and the lamp holder are mechanically and electrically connected through the first connecting structure and the second connecting structure.

[0010] In some examples, one of the first connection structure and the second connection structure includes a plurality of hooks that are spaced apart around the central axis of the lamp post; the other of the first connection structure and the second connection structure includes a plurality of slots that are hooked and connected one-to-one with the plurality of hooks.

[0011] In some examples, the floor lamp satisfies at least one of the following:

[0012] One of the first connecting structure and the second connecting structure includes two hooks, and the other of the first connecting structure and the second connecting structure includes two slots;

[0013] The first connecting structure includes the hook, and the second connecting structure includes the slot;

[0014] The multiple hooks are symmetrically distributed about the central axis of the lamp post.

[0015] In some examples, the slot includes an arc-shaped locking groove and an insertion port for inserting the hook. The insertion port is circumferentially arranged and communicates with the arc-shaped locking groove. The hook slides from the insertion port into the arc-shaped locking groove so that it hooks onto the side wall of the arc-shaped locking groove, thereby preventing the lamp post from detaching from the lamp holder along its central axis.

[0016] In some examples, one of the surfaces of the lamp post and the lamp holder has at least one locking hole, and the other surface of the lamp post and the lamp holder has a protrusion; the protrusion is confined in the locking hole when the latch slides from the socket into the arc-shaped locking groove to restrict the rotation of the lamp post relative to the lamp holder.

[0017] In some examples, the protrusion is an elastic element that provides elastic force along the central axis of the lamp post when confined to the locking hole.

[0018] In some examples, the surface where the locking hole is located also has at least one arc-shaped guide groove, with the locking hole located at one end of the arc-shaped guide groove, and the protrusion sliding along the arc-shaped guide groove toward the locking hole when the hook slides from the socket into the arc-shaped locking groove.

[0019] In some examples, the arc-shaped guide groove has a bevel at one end near the locking hole.

[0020] In some examples, multiple locking holes and multiple arc-shaped guide grooves are provided, with each arc-shaped guide groove corresponding to a locking hole. The multiple arc-shaped guide grooves are symmetrically distributed about the central axis of the lamp post, and the multiple locking holes are symmetrically distributed about the central axis of the lamp post.

[0021] In some examples, the floor lamp satisfies at least one of the following:

[0022] The surface of either the lamp post or the lamp holder has two locking holes and two arc-shaped guide grooves;

[0023] The locking hole and the arc-shaped guide groove are located on the surface of the lamp post.

[0024] In some examples, the first connection structure further includes a first electrical connector and two second electrical connectors, the two second electrical connectors being symmetrically distributed about the central axis of the lamp post, and the first electrical connector being located between the two second electrical connectors;

[0025] The second connection structure includes a third electrical connector and two fourth electrical connectors. The two fourth electrical connectors are symmetrically distributed about the central axis of the lamp post, and the third electrical connector is located between the two fourth electrical connectors. When the floor lamp is connected, the first electrical connector is in contact with the third electrical connector, and the two second electrical connectors are in contact with the two fourth electrical connectors respectively.

[0026] The beneficial effects of the technical solutions provided in this application include at least the following:

[0027] By arranging a first connecting structure at one end of the lamp post and a second connecting structure at the lamp holder, the lamp post and lamp holder are mechanically and electrically connected in a detachable manner through the cooperation of the first and second connecting structures. This allows the lamp post and lamp holder of the floor lamp to be packaged, transported, and stored separately, and then assembled into one unit before use. This floor lamp avoids the inconvenience caused by its large overall length and uneven weight distribution during packaging, transportation, and storage, and helps reduce logistics costs.

Detailed Implementation

[0042] Figure 1 This is a structural schematic diagram of a floor lamp provided in an embodiment of this application, as shown below. Figure 1 As shown, the floor lamp includes a lamp base 20 and a lamp post 10. Figure 2 This is an exploded structural diagram of a floor lamp provided in an embodiment of this application, as shown below. Figure 2 As shown, one end 10a of the lamp post 10 has a detachable connection with the lamp holder 20.

[0043] The end 10a of the lamp post 10, which is used to connect to the lamp holder 20, has a first connection structure 11. Figure 3 This is a schematic diagram of the structure of a lamp holder for a floor lamp provided in an embodiment of this application, as shown below. Figure 3As shown, the lamp holder 20 has a second connecting structure 21, and the lamp post 10 is mechanically and electrically connected to the lamp holder 20 at one end 10a, which is connected to the lamp holder 20, through the first connecting structure 11 and the second connecting structure 21.

[0044] By arranging a first connecting structure 11 at one end 10a of the lamp post 10 and a second connecting structure 21 at the lamp holder 20, the lamp post 10 and the lamp holder 20 are mechanically and electrically connected in a detachable manner through the cooperation of the first connecting structure 11 and the second connecting structure 21. This allows the lamp post 10 and the lamp holder 20 of the floor lamp to be packaged, transported, and stored separately, and then assembled into one unit before use. This floor lamp avoids the inconvenience caused by its large overall length and uneven weight distribution during packaging, transportation, and storage, and helps to reduce logistics costs.

[0045] The surface of the lamp holder 20 may have a slot 20a, and the second connecting structure 21 may be located in the slot 20a. When the lamp pole 10 is connected to the lamp holder 20, one end 10a of the lamp pole 10 is located in the slot 20a. Through the cooperation between the slot 20a and the lamp pole 10, the lamp pole 10 can be made more stable and prevent the lamp pole 10 from tilting.

[0046] For example, the lamp holder 20 may include a housing, a portion of which is recessed to form a slot 20a.

[0047] Figure 4 This is a schematic diagram of the end structure of the lamp post of a floor lamp provided in an embodiment of this application, as shown below. Figure 4 As shown, in some examples, the first connection structure 11 may include a plurality of hooks 111, which are spaced apart around the central axis of the lamp post 10.

[0048] Reference Figure 3 The second connection structure 21 may include multiple card slots 211, and the multiple card slots 211 are hooked and connected to multiple card hooks 111 in a one-to-one correspondence.

[0049] In the embodiments of this application, "multiple" can refer to two or more.

[0050] The connection between the lamp post 10 and the lamp holder 20 is achieved by using hooks 111 and slots 211. This method is not only simple in structure but also convenient in assembly and disassembly. Since multiple hooks 111 are spaced apart around the central axis of the lamp post 10, the lamp post 10 is constrained in multiple directions, ensuring a stable connection with the lamp holder 20 and preventing it from easily coming loose.

[0051] The hook 111 can be located at the end face of the lamp post 10, and the slot 211 can be located at the bottom of the slot 20a. When assembling the lamp post 10 and the lamp holder 20, the hook 111 can be aligned with the slot 211 for assembly, which is relatively simple.

[0052] As an example, the first connecting structure 11 may include two hooks 111, and the second connecting structure 21 may include two slots 211.

[0053] Only two hooks 111 are arranged, which can not only connect the lamp post 10 and the lamp holder 20 relatively stably, but also make it more convenient and easier to operate when assembling the lamp post 10 and the lamp holder 20.

[0054] Figure 5 This is a top view of the lamp holder of a floor lamp provided in an embodiment of this application, as shown below. Figure 5 As shown, the slot 211 includes an arc-shaped locking groove 2111 and an insertion port 2112 for inserting the hook 111. The insertion port 2112 and the arc-shaped locking groove 2111 are arranged circumferentially and communicate with each other. The hook 111 slides from the insertion port 2112 into the arc-shaped locking groove 2111, so that the hook 111 is hooked on the side wall of the arc-shaped locking groove 2111, thereby preventing the lamp post 10 from disengaging from the lamp holder 20 along its central axis.

[0055] When assembling the lamp post 10 and the lamp holder 20, the hook 111 can be inserted into the socket 2112, and the lamp post 10 can be rotated around its central axis to allow the hook 111 to slide into the arc-shaped locking groove 2111 to form a fit, thus connecting the lamp post 10 and the lamp holder 20 as one unit. The lamp post 10 and the lamp holder 20 are connected by rotation, making the assembly process relatively convenient. Users can even hold the lamp post 10 with one hand and insert it into the slot 20a and rotate it.

[0056] The shape of the socket 2112 can be based on the shape of the hook 111. For example, the shape of the socket 2112 can be the same as the shape of the hook 111 projected onto the end face of the lamp post 10. The arc-shaped locking groove 2111 can be arc-shaped, and the center of the circle can be located on the central axis of the lamp post 10.

[0057] Figure 6 This is a front view of the end face of the lamp post of a floor lamp provided in an embodiment of this application, such as... Figure 6 As shown, multiple hooks 111 can be centrally symmetrically distributed about the central axis of the lamp post 10. In this example, the end of the lamp post 10 has two hooks 111, and the two hooks 111 are centrally symmetrically distributed about the central axis of the lamp post 10.

[0058] The slots 211 and hooks 111 are arranged in a one-to-one correspondence, and multiple slots 211 can also be symmetrically distributed about the central axis of the lamp post 10.

[0059] When assembling the lamp post 10 and lamp holder 20, it is typically necessary to rotate the lamp post 10 around its central axis to align each hook 111 with the socket 2112. Since the multiple hooks 111 are centrally symmetrically distributed, during the rotation of the lamp post 10, there are at least two positions where each hook 111 is aligned with the socket 2112. For example, if the lamp post 10 is rotated until each hook 111 is aligned with the socket 2112, and then rotated another 180°, each hook 111 will still be aligned with the socket 2112. This makes it easier for the hooks 111 to align with the socket 2112, facilitating assembly for the user.

[0060] Floor lamps, when lit, typically do not emit light evenly in all directions, but rather in a biased direction. For example, see [reference needed]. Figure 1 As shown, one side of the lamp post 10 has a light-emitting surface 10b, and the light emitted by the floor lamp is mainly transmitted from the light-emitting surface 10b to the outside of the lamp post 10.

[0061] For example, multiple light-emitting devices, such as light-emitting diodes, may be distributed inside the lamp post 10. These multiple light-emitting devices may be arranged along the length of the lamp post 10. The light emitted by the light-emitting devices is emitted from the light-emitting surface 10b.

[0062] In some situations, users may want to change the direction of the floor lamp's illumination. For example, if the floor lamp is placed near a wall and the light was originally directed towards the wall, the user may want the light to shine away from the wall. Because the multiple latches 111 are centrally symmetrically distributed about the central axis of the lamp post 10, when changing the direction of the floor lamp's illumination, the user does not need to move the lamp holder 20. They can detach the lamp post 10 from the lamp holder 20, rotate the lamp post 10 180° around its central axis, and then reconnect it to the lamp holder 20. This centrally symmetrical distribution avoids moving the relatively bulky lamp holder 20 in similar scenarios. The lamp holder 20 is usually also connected to a power cord; eliminating the need to move the lamp holder 20 also avoids moving the power cord and prevents it from becoming cluttered.

[0063] In this example, the first connecting structure 11 includes a hook 111, and the second connecting structure 21 includes a slot 211. In some other possible implementations, the positions of the hook 111 and the slot 211 can also be interchanged, that is, the first connecting structure 11 includes the slot 211, and the second connecting structure 21 includes the hook 111.

[0064] like Figure 5 As shown, the surface of the lamp holder 20 has a protrusion 201. (As indicated...) Figure 6 As shown, the surface of the lamp post 10 also has a locking hole 101. The protrusion 201 is restricted in the locking hole 101 when the hook 111 slides from the insertion port 2112 into the arc-shaped locking groove 2111, so as to restrict the lamp post 10 from rotating relative to the lamp holder 20.

[0065] During the assembly of the lamp post 10 and the lamp holder 20, rotate the lamp post 10 so that the locking hole 101 aligns with the protrusion 201. The protrusion 201 enters the locking hole 101 and engages with it, which can restrict the rotation of the lamp post 10 relative to the lamp holder 20 to a certain extent, so as to prevent the lamp post 10 from coming loose during the use of the floor lamp.

[0066] During assembly, when the lamp post 10 is rotated and the locking hole 101 is aligned with the protrusion 201, a sound will be produced at the connection between the lamp post 10 and the lamp holder 20. For example, the "click" sound produced when the protrusion 201 enters the locking hole 101 will make the user aware that the lamp post 10 has been installed in place and prevent the user from over-tightening the lamp post 10.

[0067] When it is necessary to separate the lamp post 10 and the lamp holder 20, the user can hold the lamp post 10 and rotate it forcefully to separate the protrusion 201 from the locking hole 101.

[0068] In some examples, the protrusion 201 can be an elastic element that provides elastic force along the central axis of the lamp post 10 when the protrusion 201 is confined to the locking hole 101.

[0069] Although the latch 111 prevents the lamp post 10 and lamp holder 20 from separating along the central axis of the lamp post 10 after sliding into the arc-shaped locking groove 2111, the lamp post 10 and lamp holder 20 may still experience slight relative movement due to the assembly gap. In this example, the protrusion 201 is elastic. After entering the locking hole 101, the protrusion 201 can abut against the surface of the lamp post 10. The elasticity of the protrusion 201 can weaken or even eliminate the effect of the assembly gap, thereby reducing the range of relative movement between the lamp post 10 and lamp holder 20.

[0070] In addition, when the elastic protrusion 201 is aligned with the locking hole 101, the protrusion 201 can generate a more obvious vibration and the sound emitted is also more obvious.

[0071] Exemplarily, the protrusion 201 may include a protrusion 2011 and a connecting handle 2012, one end of which is connected to the protrusion 2011, and the other end of which is connected to the housing of the lamp holder 20. The extending direction of the connecting handle 2012 may intersect the insertion direction of the lamp post 10, that is, the extending direction of the central axis of the lamp post 10. For example, the extending direction of the connecting handle 2012 may be perpendicular to the insertion direction of the lamp post 10. The connecting handle 2012 bends when the protrusion 2011 is pressed, thereby providing elasticity.

[0072] As an example, the locking hole 101 can be located at the end face of the lamp post 10, and the protrusion 201 can be located at the bottom of the slot 20a.

[0073] In other possible implementations, the locking hole 101 may also be located on the side wall of the lamp post 10, and the protrusion 201 may be located on the side wall of the slot 20a.

[0074] like Figure 6 As shown, the surface where the locking hole 101 is located also has at least one arc-shaped guide groove 102, and the locking hole 101 is located at one end of the arc-shaped guide groove 102. When the hook 111 slides into the arc-shaped locking groove 2111 from the insertion port 2112, the protrusion 201 slides along the arc-shaped guide groove 102 toward the locking hole 101.

[0075] During the rotation of the lamp post 10 and the assembly of the lamp post 10 and lamp holder 20, the arc-shaped guide groove 102 can temporarily accommodate the protrusion 201, preventing the protrusion 201 from excessively squeezing and scratching the surface of the lamp post 10, thus avoiding damage to the surface of the lamp post 10 and the surface of the protrusion 201, which helps to extend the service life of the floor lamp. The arc-shaped guide groove 102 also guides the protrusion 201 to slide into the locking hole 101.

[0076] For example, the arc-shaped guide groove 102 can be arc-shaped, and the center of the circle can be located on the central axis of the lamp post 10.

[0077] like Figure 6 As shown, the arc-shaped guide groove 102 has an inclined surface 102a at one end near the locking hole 101.

[0078] When the protrusion 201 slides in the arc-shaped guide groove 102 to the inclined surface 102a, it is easier to slide out of the arc-shaped guide groove 102 and move into the locking hole 101 under the action of the inclined surface 102a.

[0079] In some examples, multiple locking holes 101 and arc-shaped guide grooves 102 can be provided, with the arc-shaped guide grooves 102 and locking holes 101 arranged in a one-to-one correspondence. The multiple arc-shaped guide grooves 102 are centrally symmetrically distributed about the central axis of the lamp post 10, and the multiple locking holes 101 are centrally symmetrically distributed about the central axis of the lamp post 10.

[0080] Multiple hooks 111 are centrally symmetrically distributed about the central axis of the lamp post 10, ensuring that the lamp post 10 can still be connected to the lamp holder 20 after rotating 180° around its central axis during assembly. Multiple locking holes 101 and multiple arc-shaped guide grooves 102 are also arranged centrally symmetrically, ensuring that the protrusion 201 can always slide into the locking hole 101 during assembly, thus restricting the relative rotation of the lamp post 10 and the lamp holder 20.

[0081] The protrusions 201 can be arranged one-to-one with the locking holes 101, and the multiple protrusions 201 can be symmetrically distributed about the central axis of the lamp post 10. In this way, after the lamp post 10 and the lamp holder 20 are assembled in place, the multiple protrusions 201 can slide into the multiple locking holes 101 respectively, and the multiple protrusions 201 and the multiple locking holes 101 together restrict the relative rotation of the lamp post 10 and the lamp holder 20.

[0082] As an example, the surface of the lamp post 10 may have two locking holes 101 and two arc-shaped guide grooves 102, and the lamp holder 20 may have two protrusions 201.

[0083] By using two protrusions 201 in conjunction with two locking holes 101, the relative rotation of the lamp post 10 and the lamp holder 20 can be relatively stably restricted, while avoiding an overly complex structure for the lamp post 10 and the lamp holder 20, which would increase manufacturing costs.

[0084] In this example, the locking hole 101 is located on the surface of the lamp post 10, and the protrusion 201 is located on the surface of the lamp holder 20. In some other possible implementations, the positions of the locking hole 101 and the protrusion 201 can also be interchanged, that is, the protrusion 201 is located on the surface of the lamp post 10, and the locking hole 101 is located on the surface of the lamp holder 20.

[0085] like Figure 6 As shown, the first connection structure 11 may further include two second electrical connectors 103, which are symmetrically distributed about the central axis of the lamp post 10; see reference. Figure 5 The second connection structure 21 may further include two fourth electrical connectors 203, which are symmetrically distributed about the central axis of the lamp post 10. When the floor lamp is connected, the two second electrical connectors 103 are in contact with the two fourth electrical connectors 203 respectively; that is, one second electrical connector 103 is in contact with one fourth electrical connector 203, and the other second electrical connector 103 is in contact with the other fourth electrical connector 203.

[0086] The lamp post 10 requires power from the lamp holder 20 when it is in operation. The lamp post 10 and the lamp holder 20 are electrically connected through the contact between the second electrical connector 103 and the fourth electrical connector 203.

[0087] The two second electrical connectors 103 are centrally symmetrically distributed, and the two fourth electrical connectors 203 are also centrally symmetrically distributed, so that when the lamp post 10 is separated from the lamp holder 20, and the lamp post 10 is rotated 180° relative to the lamp holder 20 and then reassembled, the two second electrical connectors 103 can still contact the two fourth electrical connectors 203 respectively, ensuring normal electrical connection.

[0088] As an example, the second electrical connector 103 may include a conductive sheet, and the fourth electrical connector 203 may include a spring pin. In other possible implementations, the second electrical connector 103 may also include a spring pin, and the fourth electrical connector 203 may include a conductive sheet.

[0089] Figure 7 yes Figure 6 Section I-I in the diagram, as shown Figure 7 As shown, a first circuit board 105 may be disposed inside the lamp post 10, located within the lamp post 10 and fixed to its end. The end of the lamp post 10 may have a through hole 10c exposing the first circuit board 105. A conductive sheet may be located on the surface of the first circuit board 105, meaning the second electrical connector 103 may include a metal layer located on the surface of the first circuit board 105. Exemplarily, the second electrical connector 103 may be fan-shaped. A spring pin may abut against the surface of the second electrical connector 103 under its own elasticity, ensuring electrical connection during movement of the spring pin on the surface of the second electrical connector 103.

[0090] like Figure 6 As shown, the first connection structure 11 may further include a first electrical connector 104, which is located between two second electrical connectors 103. (Refer to again...) Figure 5 The second connection structure 21 may also include a third electrical connector 204, which is located between the two fourth electrical connectors 203. When the floor lamp is in the connected state, the first electrical connector 104 is in contact with the third electrical connector 204.

[0091] For example, both the first electrical connector 104 and the third electrical connector 204 can be located on the central axis of the lamp post 10, so that the first electrical connector 104 and the third electrical connector 204 can remain in contact during the rotation of the lamp post 10 around the central axis of the lamp post 10.

[0092] In some examples, the first electrical connector 104 and the third electrical connector 204 can serve as control electrodes. The contact between the first electrical connector 104 and the third electrical connector 204 can be used to transmit control signals, such as control signals to control the on / off state of the light-emitting device, control signals to control the brightness of the light-emitting device, control signals to control the color of the light-emitting device, and control signals to control the light-emitting mode of the light-emitting device. The light-emitting mode may, for example, include a mode in which the brightness gradually changes or a mode in which the color of the light-emitting device gradually changes.

[0093] In some other possible implementations, the first electrical connector 104 and the third electrical connector 204 can also serve as grounding electrodes. By contacting the first electrical connector 104 and the third electrical connector 204, the lamp post 10 can be grounded.

[0094] For example, the outer casing or part of the outer casing of the lamp post 10 can be made of metal. By grounding the lamp post 10, the risk of electric shock when using the floor lamp can be reduced.

[0095] For example, static electricity may accumulate in parts of the lamp post 10. Grounding can release the static electricity and prevent it from having an adverse effect on the lamp post 10.

[0096] For example, the first electrical connector 104 may be connected to the first circuit board 105 to release static electricity that may accumulate on the first circuit board 105.

[0097] As an example, the first electrical connector 104 may include a conductive sheet, and the third electrical connector 204 may include a spring pin. In other possible implementations, the first electrical connector 104 may also include a spring pin, and the third electrical connector 204 may include a conductive sheet.

[0098] As an example, the first electrical connector 104 may include a metal layer located on the surface of the first circuit board 105. Exemplarily, the first electrical connector 104 may be circular, and two annular second electrical connectors 103 may be arranged around the first electrical connector 104. A gap is provided between the first electrical connector 104 and the two second electrical connectors 103, thereby insulating the first electrical connector 104 from the two second electrical connectors 103.

[0099] like Figure 7 As shown, a second circuit board 106 can also be installed inside the lamp post 10, and the second circuit board 106 can be connected to the first circuit board 105. A power supply circuit can be installed on the second circuit board 106, which is used to supply power to the light-emitting device.

[0100] The floor lamp may also include a power supply circuit located in the lamp post 10. Figure 8 This is a power supply circuit diagram of a light-emitting device for a lamp post provided in an embodiment of this application, such as... Figure 8 As shown, the power supply circuit may include a diode bridge, which comprises four diodes D1. The four diodes D1 are divided into two pairs, with two diodes in each pair connected in series, and the two pairs of diodes D1 connected in parallel. The two input terminals V of the diode bridge are... in It is connected to two second electrical connectors 103 respectively. The two output terminals V of the diode bridge... out The light-emitting devices of the lamp post 10 are connected respectively. For example, the two input terminals V of the diode bridge... in The voltage between them can be 12V.

[0101] The lamp post 10 is separated from the lamp holder 20. The lamp post 10 is rotated 180° around its central axis and then reconnected to the lamp holder 20. With the two fourth electrical connectors 203 as references, the two second electrical connectors 103 are interchanged. This causes the two input terminals V of the diode bridge to... in The polarities of the diodes are reversed. However, under the action of a diode bridge, the two output terminals V of the diode bridge... out The polarity will not change, so the power supply of the light-emitting device will not be affected.

[0102] The power supply circuit may also include protection devices. For example, the protection device may include a transient voltage suppressor diode D2, which may be connected to the two output terminals V of the diode bridge. out In between, the transient voltage suppressor D2 provides overvoltage protection. When a surge voltage pulse occurs momentarily in the power supply circuit, the transient voltage suppressor D2 changes from a high-resistance state to a low-resistance state, shunting and clamping the surge voltage, thereby preventing the light-emitting device from being damaged by the momentary surge voltage pulse.

[0103] Figure 9 yes Figure 5 Section II-II in the diagram, as shown Figure 9 As shown, a third circuit board 205 can be disposed inside the lamp holder 20. For example, the third circuit board 205 can be arranged corresponding to the bottom of the slot 20a, and the third circuit board 205 can be connected to the housing of the lamp holder 20 by screws. The fourth electrical connector 203 and the third electrical connector 204 can be connected to the third circuit board 205. The fourth electrical connector 203 and the third electrical connector 204 can penetrate through the bottom of the slot 20a and extend into the slot 20a so as to be able to contact the second electrical connector 103 and the first electrical connector 104.

[0104] Figure 10 This is a schematic diagram illustrating the assembly process of a floor lamp according to an embodiment of this application. Figure 10 The floor lamp shown is still in a separate state. This is to demonstrate the connection between the lamp post 10 and the lamp base 20. Figure 10 At least some parts of the structure of the lamp holder 20 are omitted, such as part of the housing of the lamp holder 20 and the third circuit board 205. Figure 10 As shown, during the assembly of the lamp post 10 and lamp holder 20, the lamp post 10 can be inserted into the slot 20a first, so that the hook 111 is aligned with the socket 2112 and passes through the socket 2112. At this time, the protrusion 201 is located in the arc-shaped guide groove 102, the second electrical connector 103 is in contact with the fourth electrical connector 203, and the first electrical connector 104 is in contact with the third electrical connector 204.

[0105] Figure 11 This is a schematic diagram illustrating the assembly process of a floor lamp according to an embodiment of this application. Figure 11The floor lamp shown is still connected. This is to demonstrate the connection between the lamp post 10 and the lamp base 20. Figure 11 The design also omits at least some parts of the lamp holder 20's structure, such as part of the lamp holder 20's housing and the third circuit board 205. Figure 11 As shown, in the separated state, the lamp post 10 is rotated around its own central axis, causing the hook 111 to slide into the arc-shaped locking groove 2111. During the rotation, the protrusion 201 moves along the arc-shaped guide groove 102, moves to the outside of the arc-shaped guide groove 102 at the inclined surface 102a, and finally enters the locking hole 101. During this process, the second electrical connector 103 contacts the fourth electrical connector 203, and the first electrical connector 104 contacts the third electrical connector 204. When it is necessary to separate the lamp post 10 and the lamp holder 20, this operation is sufficient.
