Description

Technical Field

[0001] The present invention relates to lighting devices, and particularly to a lamp and its conductive rod that are convenient for assembly. Background Art

[0002] Consumers purchase general table lamps or floor lamps. If the lamp is already assembled, the volume of the usual packaging is quite large, which not only makes transportation and handling difficult but also increases the freight cost. If the lamp requires the consumer to assemble it after purchase, it is necessary to thread the wire through multiple rods, which has the problem of difficult assembly. If the wire is in a state where it does not need to be threaded through the rod but is exposed outside the rod, this not only affects the aesthetics but also poses a risk of being pulled and knocked down. Therefore, it is necessary to provide a lamp that meets market demands. Summary of the Invention

[0008] Another technical means of the present invention is that the positioning section of the conductive strip has a neck connected to the stretching section and a tapered portion connected to the neck and protruding out of the insulating fastener. The diameter of the neck is smaller than the maximum diameter of the tapered portion.

[0011] Another technical means of the present invention lies in that the stop portion of the insulating fastener further has another positioning hole, and the conductive sheet further has a second penetrating section bent from the connecting section and extending in the same direction as the first penetrating section. The first penetrating section and the second penetrating section respectively pass through the positioning hole and the another positioning hole.

[0012] Another technical means of the present invention lies in that the outer tube unit includes a hollow tube body and at least one positioning member provided on the hollow tube body. The insulating fastener further has a convex wall portion extending radially outward along the stop portion. The insulating fastener is combined on the positioning member, and the convex wall portion abuts against the positioning member.

[0013] Another technical means of the present invention lies in that the hollow tube body is formed with an internal thread, the positioning member is formed with an external thread, and the positioning member is screwed into the hollow tube body and can adjust its position relative to the hollow tube body.

[0014] Another object of the present invention is to provide a lamp, comprising at least one conductive rod as described above, a lamp holder combined above the conductive rod, and a base combined below the conductive rod.

[0029] The relevant patent features and technical content of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the accompanying drawings. Before the detailed description, it should be noted that similar elements are denoted by the same reference numerals.

[0030] Refer to Figure 1 , which is the first preferred embodiment of the lighting fixture of the present invention, including a conductive rod 1, a lamp base 5 combined above the conductive rod 1, and a base 6 combined below the conductive rod 1. It should be particularly noted that the lighting fixture of the present invention is applicable to a low-voltage power supply. In another embodiment, the lighting fixture of the present invention can combine multiple conductive rods 1 to increase the distance between the lamp base 5 and the base 6.

[0031] Refer to Figure 2 , the conductive rod 1 includes an outer tube unit 2 made of a conductive material, two insulating fasteners 3 respectively disposed at both ends of the outer tube unit 2, and a conductive unit 4 extending through the outer tube unit 2. The outer tube unit 2 includes a hollow tube body 21 surrounding the inner space of the tube and two positioning members 22 disposed inside the hollow tube body 21. The two insulating fasteners 3 are respectively combined with the two positioning members 22 (for example Figure 2 the positioning member 22 independent of the hollow tube body 21 in ). In another embodiment, the wall thickness of the hollow tube body 21 can also be used to form a convex ridge for positioning the insulating fastener 3 on the hollow tube body 21. Inner threads are formed at both ends of the hollow tube body 21, and outer threads are formed on the positioning member 22. Therefore, the positioning member 22 is screwed into the hollow tube body 21 and can adjust its position relative to the hollow tube body 21.

[0032] Refer to Figure 3 , each insulating fastener 3 has a sleeve portion 31, a stop portion 32 located at one end of the sleeve portion 31, a through groove portion 33 recessed radially along the sleeve portion 31 and the stop portion 32, and a convex ridge portion 34 extending radially outward along the stop portion 32. In addition, as Figure 2 shown, each insulating fastener 3 abuts against the corresponding positioning member 22 via the convex ridge portion 34. That is to say, the insulating fastener 3 will not detach from the positioning member 22 due to the clamping of its convex ridge portion 34. In another embodiment, the stop portion 32 further has two positioning holes 321 for completing the electrical conduction of the lighting fixture of the present invention, as will be described in detail later.

[0033] The conductive unit 4 includes a conductive bar 41, and the conductive bar 41 has a stretching section 411 and two positioning sections 412 respectively connected to both ends of the stretching section 411. Among them, the positioning section 412 of the conductive bar 41 abuts against the stop portion 32 of the insulating fastener 3, so that the stretching section 411 of the conductive bar 41 can penetrate through the hollow tube body 21 of the outer tube unit 2, and the two positioning sections 412 located at both ends of the conductive bar 41 can be respectively positioned on the two positioning members 22 of the outer tube unit 2 by means of the insulating fastener 3. Each positioning section 412 has a neck portion 413 connected to the stretching section 411 and a tapered portion 414 connected to the neck portion 413 and protruding from the insulating fastener 3. The diameter of the neck portion 413 is smaller than the maximum diameter of the tapered portion 414, and the tapered portion 414 tapers in a direction away from the neck portion 413 and is in a tapered shape.

[0034] Refer to Figure 4-1 , which illustrates the assembly method of the conductive bar 41. First, it should be noted that in this embodiment, the conductive bar 41 is a stretching spring and has stretching elasticity, but this is not limited in actual implementation. First, as shown in (a) of Figure 4-1 , the two positioning members 22 are screwed onto both ends of the hollow tube body 21. Then, as shown in (b) of Figure 4-1 , one of the insulating fasteners 3 is installed on the positioning section 412 on the left side of the conductive bar 41. With reference to Figure 2 and Figure 3 , the positioning section 412 passes through the through slot portion 33 of the insulating fastener 3 with the neck portion 413, so that the tapered portion 414 abuts against the stop portion 32 and is positioned on the insulating fastener 3. At this time, the tapered portion 414 protrudes from the insulating fastener 3 along the axial direction of the sleeve portion 31.

[0035] Continue to refer to Figure 4-1 in (b). The pulling tool 91 passes through the hollow tube body 21, hooks the positioning section 412 on the right side of the conductive bar 41, and pulls the conductive bar 41 through the pulling tool 91 so that it enters and penetrates through the hollow tube body 21 from the left side of the hollow tube body 21 until the insulating fastener 3 installed on the left side of the conductive bar 41 is engaged with the positioning member 22 on the left side of the hollow tube body 21, as shown in (c) of Figure 4-1 . Then, the pulling tool 91 continuously pulls the positioning section 412 on the right side of the conductive bar 41 out of the hollow tube body 21, as shown in (d) of Figure 4-2 . Again, as shown in (e) of Figure 4-2 , and the other insulating fastener 3 is installed on the positioning section 412 on the right side of the conductive bar 41. Then, the pulling tool 91 is disassembled and separated from the positioning section 412. The elastic restoring force of the conductive bar 41 will cause the positioning section 412 to return to the hollow tube body 21, and the insulating fastener 3 will be engaged with the positioning member 22 on the right side of the hollow tube body 21, as shown in (f) of Figure 4-2As shown in (f) thereof, the assembly of the conductive bar 41 is thus completed. Through the stretching action during the assembly process, the conductive bar 41 is in a nearly taut state, which can ensure that the conductive bar 41 will not contact the hollow tube body 21 and cause a short circuit. In this embodiment, the two positioning members 22 are located inside the hollow tube body 21 and do not protrude from both ends of the hollow tube body 21. After the two insulating fasteners 3 are respectively coupled to the two positioning members 22, they are also located inside the hollow tube body 21, making the conductive rod 1 designed with female ends at both ends.

[0036] Refer to again Figure 5 , the lamp socket 5 includes a first joint portion 51 detachably coupled to one end of the outer tube unit 2 and made of a conductive material, a first conductive connection portion 52 located inside the first joint portion 51, and a light-emitting portion 53 electrically connected to the first joint portion 51 and the first conductive connection portion 52. The first joint portion 51 and the first conductive connection portion 52 do not contact each other. More specifically, the first joint portion 51 is a metal tube, and the ends of the first joint portion 51 are installed with the insulating fasteners 3 and the conductive sheets 42 as described above. Therefore, the first joint portion 51 is electrically non-contact with the first conductive connection portion 52 due to the insulating property of the insulating fasteners 3. Refer to Figure 6 , the conductive sheet 42 has a first penetrating section 421, a connecting section 422 bent from the first penetrating section 421, and a second penetrating section 423 bent from the connecting section 422 and extending in the same direction as the first penetrating section 421. The first penetrating section 421 and the second penetrating section 423 respectively pass through the two positioning holes 321 on the insulating fastener 3, so that the connecting section 422 is positioned and exposed on the stop portion 32 of the corresponding insulating fastener 3. Among them, the connecting section 422 forms Figure 5 the first conductive connection portion 52 in

[0037] Refer to Figure 7 , the base 6 includes a second joint portion 61 detachably coupled to the other end of the outer tube unit 2 and made of a conductive material, a second conductive connection portion 62 located inside the second joint portion 61, and a circuit board 63 electrically connected to the second joint portion 61 and the second conductive connection portion 62. The second joint portion 61 and the second conductive connection portion 62 do not contact each other. More specifically, the second joint portion 61 is a metal tube, and the ends of the second joint portion 61 are installed as Figure 6The insulating fastener 3 and the conductive sheet 42 shown. Therefore, the second engaging portion 61 is electrically non - contacting with the second conducting portion 62 by virtue of the insulating property of the insulating fastener 3. The conductive sheet 42 also forms the second conducting portion 62 with its connecting section 422, which will not be elaborated here. It should be noted that the second engaging portion 61 of the base 6 will also be connected to the circuit board 63 by using the conductive sheet 42b and the negative - pole line 92 independently embedded inside, while the second conducting portion 62 is connected to the circuit board 63 via the positive - pole line 93.

[0038] Refer again to Figure 5 , when the lamp holder 5 is combined with the outer - tube unit 2, the first engaging portion 51 of the lamp holder 5 is screwed to one end of the hollow tube body 21 by its external thread. At this time, the first conducting portion 52 of the lamp holder 5 presses the tapered portion 414 of the conductive bar 41 to form an electrical connection. Refer to Figure 7 , when the base 6 is combined with the outer - tube unit 2, the second engaging portion 61 of the base 6 is screwed to the other end of the hollow tube body 21. At this time, the second conducting portion 62 of the base 6 presses another tapered portion 414 of the conductive bar 41 to form an electrical connection. Since the hollow tube body 21, the first engaging portion 51 of the lamp holder 5, and the second engaging portion 61 of the base 6 are all made of conductive materials, therefore, after the lamp holder 5 and the base 6 are both properly combined with the conductive rod 1, the hollow tube body 21, the first engaging portion 51, and the second engaging portion 61 will form an electrical connection to serve as the negative pole, or commonly known as the ground wire. In addition, the first conducting portion 52 of the lamp holder 5, the conductive bar 41, and the second conducting portion 62 of the base 6 will also form an electrical connection to serve as the positive pole, or commonly known as the live wire. The insulating fastener 3 is used as an insulating structure between the positive - pole circuit and the negative - pole circuit to prevent the two from forming a conduction path.

[0039] In the lamp of the present invention, the conductive unit 4 uses the positioning section 412 protruding from the insulating fastener 3 to contact the next component to be electrically connected (such as the lamp holder, the base, the conductive rod), thereby completing the electrical connection. In a preferred embodiment of the present invention, the positioning section 412 of the conductive unit 4 includes a tapered portion 414 protruding from the insulating fastener 3, and the tapered portion 414 is in a spiral shape. When the conductive rod 1 is screwed to the lamp holder 5 or the base 6, the tapered portion 414 is compressed and can tightly abut against the conductive sheet 42 of the lamp holder 5 or the conductive sheet 42 of the base 6. The compressed spiral - shaped tapered portions 414 do not overlap with each other, thus increasing the contact area between it and the lamp holder 5 or the base 6 and achieving a better electrical - connection effect.

[0040] As Figure 1 , Figure 5 and Figure 7As shown, with the above design, as long as the base 6, the conductive rod 1, and the lamp socket 5 are tightened together, an electrically conductive state can be formed, without the need to additionally arrange wires inside, nor will there be a phenomenon of wires being exposed outside. For the manufacturer, during the assembly process of the conductive rod 1, as long as the insulating fasteners 3 are installed on both sides of the conductive strip 41 and the insulating fasteners 3 are positioned on the positioning members 22 on both sides of the hollow tube body 21, the assembly steps can be completed. For the consumer, as long as the base 6 and the lamp socket 5 are respectively screwed to both ends of the conductive rod 1, it can be used, which can simplify the assembly procedure for both the producer and the consumer. In addition, the detachable structural design can also effectively reduce the packaging volume and lower the transportation cost.

[0041] It should be particularly noted that in the first preferred embodiment of the lamp of the present invention, a conductive series connection combination is disclosed for electrically connecting a first series connection member and a second series connection member. For example, the first series connection member and the second series connection member can be respectively applied to the electrical connection between the lamp socket 5 and the conductive rod 1 as shown in Figure 5 or respectively applied to the electrical connection between the base 6 and the conductive rod 1 as shown in Figure 7 ; in another preferred embodiment, the first series connection member and the second series connection member can also be respectively applied to the electrical connection between two conductive rods 1.

[0042] In the aforementioned first preferred embodiment, only one conductive rod 1 is used to connect the base 6 and the lamp socket 5 to form a lamp with a lower height, such as a table lamp. If a lamp with a higher height, such as a floor lamp, is to be formed, multiple conductive rods 1 need to be connected in series.

[0043] Referring to Figure 8 , which is the second preferred embodiment of the lamp of the present invention, includes a plurality of serially connected conductive rods 1, a lamp socket 5 combined with the top end of the uppermost conductive rod 1, and a base 6 combined with the bottom end of the lowermost conductive rod 1. Among the plurality of conductive rods 1, the structure of one conductive rod 1a is the same as that Figure 2 disclosed, while the structure of the other conductive rod 1b is slightly different.

[0044] As shown in Figure 9 , the conductive rod 1b also includes an outer tube unit 2 made of a conductive material, two insulating fasteners 3 respectively arranged at both ends of the outer tube unit 2, and a conductive unit 4 extending through the outer tube unit 2. The outer tube unit 2 includes a hollow tube body 21 and two positioning members 22 arranged at both ends of the hollow tube body 21, and the two insulating fasteners 3 are respectively combined with the two positioning members 22. Internal threads are formed at both ends of the hollow tube body 21, and external threads are formed on the positioning members 22. Therefore, the positioning members 22 are screwed into the hollow tube body 21 and can adjust their positions relative to the hollow tube body 21. One of the positioning members 22 is located inside the hollow tube body 21, and the other positioning member 22 protrudes from one end of the hollow tube body 21. The structure of the insulating fastener 3 is the same as that Figure 3 shown, and will not be elaborated here.

[0045] The difference lies in that the conductive unit 4 disposed in the conductive rod 1b includes a conductive strip 41 and a conductive sheet 42. The conductive sheet 42 is the same as what is presented, and it has a first penetrating section 421, a connecting section 422 bent from the first penetrating section 421, and a second penetrating section 423 bent from the connecting section 422 and extending in the same direction as the first penetrating section 421. Among them, the first penetrating section 421 has a perforation 424, and the first penetrating section 421 and the second penetrating section 423 respectively pass through two positioning holes 321 of the insulating fastener 3, so that the connecting section 422 is positioned and exposed on the stopper 32 of the corresponding insulating fastener 3. Figure 6 The same as what is presented, it has a first penetrating section 421, a connecting section 422 bent from the first penetrating section 421, and a second penetrating section 423 bent from the connecting section 422 and extending in the same direction as the first penetrating section 421. Among them, the first penetrating section 421 has a perforation 424, and the first penetrating section 421 and the second penetrating section 423 respectively pass through two positioning holes 321 of the insulating fastener 3, so that the connecting section 422 is positioned and exposed on the stopper 32 of the corresponding insulating fastener 3.

[0046] The conductive strip 41 has a stretching section 411 and two positioning sections 412 respectively connected to both ends of the stretching section 411. Figure 9 The lower positioning section 412 in has a neck 413 connected to the stretching section 411 and a tapered portion 414 connected to the neck 413 and protruding from the insulating fastener 3. The diameter of the neck 413 is smaller than the maximum diameter of the tapered portion 414. The neck 413 passes through the through groove portion 33 of the insulating fastener 3, so that the tapered portion 414 abuts against the stopper 32 and is positioned on the insulating fastener 3. Figure 9 The diameter of the upper positioning section 412 in is the same as that of the stretching section 411, and its end directly hooks through the perforation 424 of the first penetrating section 421 and is positioned on the conductive sheet 42. It should be noted that in this embodiment, the lower positioning member 22 is located inside the hollow tube 21, and the upper positioning member 22 protrudes from one end of the hollow tube 21, and the length of the positioning member 22 can be changed according to actual needs. With this design, the positioning section 412 of the conductive strip 41 with the tapered portion 414 is located inside the hollow tube 21 to form a female end, and the other positioning section 412 protrudes outside the hollow tube 21 to form a male end, so that both ends of the conductive rod 1b become a male end and a female end respectively.

[0047] By connecting the conductive rod 1b with a male end and a female end in series with the conductive rod 1a with both ends being female ends, the conductive rods 1a and 1b can be respectively connected in series with the lamp socket 5 and the base 6, as Figure 8 shown. Of course, in actual implementation, the joint of the lamp socket 5 or the base 6 can also be replaced with a structure of a female end to directly connect in series with the conductive rod 1b with a male end and a female end.

[0048] In this preferred embodiment, through the structural design of the conductive rod 1b with a male end and a female end, the conductive rod 1b can be directly connected in series and extended, and the length can be changed according to needs.

[0049] It should be noted in particular that in the foregoing embodiments, between the conductive rod 1 and the lamp socket 5, between the conductive rod 1 and the base 6, and between the mutually engaged conductive rods 1, they can all be regarded as a conductive series connection combination. By using the methods in the respective embodiments to form the structure of the male end and the female end, in addition to facilitating quick engagement, the metal outer tubes are electrically connected to each other to form the negative electrode, and the internal conductive strip 41 and the conductive sheet 42 are electrically connected to each other to form the positive electrode, so that the above-mentioned components are electrically connected when engaged. Therefore, the following advantages are achieved:

[0050] 1. Easy assembly on the production line: The hollow tube body 21, the positioning member 22, the insulating fastener 3, the conductive strip 41, and the conductive sheet 42 of each conductive rod 1 are quick and convenient to assemble, so the assembly cost of the production line can be reduced.

[0051] 2. Easy transportation of the product: The conductive rod 1, the base 6, and the lamp socket 5 are of a detachable design, so the packaging volume can be reduced, the packaging materials can be reduced, which is more environmentally friendly, and at the same time, the transportation cost can be reduced.

[0052] 3. Modular design: Consumers only need to screw the conductive rod 1, the base 6, and the lamp socket 5 together to complete the assembly and conduction. Therefore, the exposed wires can be greatly reduced, the risk of being pulled and tripped can be avoided, and the overall aesthetics can also be improved.

[0053] The above are only the preferred embodiments of the present invention, and the scope of implementation of the present invention should not be limited thereby. That is, all simple equivalent changes and modifications made according to the scope of the claims of the present invention and the content of the specification still fall within the scope of the patent of the present invention.
