[0002] This application claims priority to Chinese Patent Application No. 202423182644.5, filed on December 20, 2024, entitled "Lighting Fixture", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of lighting equipment technology, and specifically relates to a lamp. Background Technology

[0004] With the development of technology, people's needs for lighting fixtures are no longer limited to presenting a variety of different lighting effects, but also require greater ease of assembly and disassembly of their components.

[0005] However, in related technologies, the lighting fixture includes an insulating inner shell and a cable. The insulating inner shell has a cable passage, through which one end of the cable extends into the inner cavity of the insulating inner shell. The cable and the inner wall of the cable passage are relatively fixed together by friction, thus mounting the cable onto the insulating inner shell. This design requires overcoming significant friction to insert the cable into the inner cavity of the insulating inner shell, making cable installation rather inconvenient. Summary of the Invention

[0006] The purpose of this application is to provide a lighting fixture that can solve the problem of inconvenient cable installation in related technologies.

[0007] This application provides a lamp, including:

[0008] The device comprises an insulating inner shell, an insulating wire clamping component, and a metal outer shell. The insulating inner shell has a wire passage opening communicating with its inner cavity and a first insulating portion. The insulating wire clamping component has a second insulating portion. The insulating wire clamping component is connected to the insulating inner shell and blocks a portion of the wire passage opening. A wire passage channel is formed between the edge of the insulating wire clamping component and the edge of the other portion of the wire passage opening. The metal outer shell is fitted over the insulating inner shell and the insulating wire clamping component. Both the first insulating portion and the second insulating portion pass through the metal outer shell.

[0009] The cable has its first end passing between the first insulation portion and the second insulation portion, and extending into the inner cavity of the insulating inner shell through the wire passage. The insulating wire clamp and the insulating inner shell together hold the cable so that the cable is fixed relative to the insulating inner shell.

[0010] In this embodiment, when the cable is clamped between the insulating inner shell and the insulating clamping member, the cable is fixed relative to the insulating inner shell, thus being installed on the insulating inner shell. When the insulating clamping member is not installed, the portion of the cable passage corresponding to the insulating clamping member is unobstructed. In this case, there is little or no friction between the cable and the cable passage. The cable can then be easily inserted into the inner cavity of the insulating inner shell, making cable installation of the lamp provided in this embodiment more convenient.

[0011] Furthermore, in this embodiment, the metal outer shell is fitted over the insulating inner shell and the insulating pressure wire component. The metal outer shell has good heat dissipation performance, thereby extending the service life of the lamp. The insulating inner shell is provided with a first insulating part, and the insulating pressure wire component is provided with a second insulating part. Both the first and second insulating parts pass through the metal outer shell. The first end of the cable passes between the first and second insulating parts and extends into the inner cavity of the insulating inner shell through the wire passage. This means that there is a first insulating part or a second insulating part between the cable and the metal outer shell. Both the first and second insulating parts can separate the cable from the metal outer shell, thereby improving the safety of the lamp. Both the first and second insulating parts can protect the cable, thereby reducing the scratches on the cable. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The lighting fixtures provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] Please refer to Figures 1 to 11. This embodiment of the application provides a lighting fixture, including an insulating inner shell 100, an insulating wire clamping member 200, a metal outer shell 500, and a cable 300. Optionally, the lighting fixture may be, for example, a downlight.

[0028] Specifically, the insulating inner shell 100 is provided with a cable passage 110 communicating with its inner cavity. The cable passage 110 allows the cable 300 to enter and exit the inner cavity of the insulating inner shell 100, and the insulating inner shell 100 is provided with a first insulating part 160.

[0029] Referring to Figures 1 to 7, the insulating wire clamping member 200 is provided with a second insulating part 250. The insulating wire clamping member 200 is connected to the insulating inner shell 100 and blocks a part of the wire passage 110. A wire passage 400 is formed between the edge of the insulating wire clamping member 200 and the edge of the other part of the wire passage 110.

[0030] The metal outer shell 500 is fitted over the insulating inner shell 100 and the insulating wire clamp 200, and the first insulating part 160 and the second insulating part 250 both pass through the metal outer shell 500.

[0031] The first end of the cable 300 passes between the first insulating part 160 and the second insulating part 250, and extends into the inner cavity of the insulating inner shell 100 through the wire passage 400. The cable 300 is, for example, a power cord for a lamp. In this case, the second end of the cable 300 is used for, for example, to connect to the mains power. The insulating wire clamp 200 and the insulating inner shell 100 together clamp the cable 300 so that the cable 300 is fixed relative to the insulating inner shell 100.

[0032] In this embodiment, when the cable 300 is sandwiched between the insulating inner shell 100 and the insulating wire clamping member 200, the cable 300 is fixed relative to the insulating inner shell 100, thereby being installed on the insulating inner shell 100. When the insulating wire clamping member 200 is not installed, the portion of the cable passage 110 corresponding to the insulating wire clamping member 200 is unobstructed. At this time, there is little or no friction between the cable 300 and the cable passage 110. In this case, the cable 300 can be easily inserted into the inner cavity of the insulating inner shell 100. Therefore, the installation of the cable 300 in the lamp provided in this embodiment is relatively convenient, which is beneficial for achieving automated installation of the cable 300.

[0033] Furthermore, in this embodiment, the metal outer shell 500 is fitted over the insulating inner shell 100 and the insulating wire clamping member 200. The metal outer shell 500 has good heat dissipation performance, thereby extending the service life of the lamp. The insulating inner shell 100 is provided with a first insulating part 160, and the insulating wire clamping member 200 is provided with a second insulating part 250. Both the first insulating part 160 and the second insulating part 250 pass through the metal outer shell 500. The first end of the cable 300 passes between the first insulating part 160 and the second insulating part 250 and extends into the inner cavity of the insulating inner shell 100 through the wire passage 400. This means that the cable 300 and the metal outer shell 500 are provided with either the first insulating part 160 or the second insulating part 250. Both the first insulating part 160 and the second insulating part 250 can separate the cable 300 from the metal outer shell 500, thereby improving the safety of the lamp. Both the first insulating part 160 and the second insulating part 250 can protect the cable 300, thereby reducing the scratches suffered by the cable 300.

[0034] In another embodiment, referring to Figures 2 to 4, the cable passage 110 includes a first sub-part 111 disposed on the side wall of the insulating inner shell 100. The insulating wire clamping member 200 includes a wire clamping portion 210, which covers a portion of the first sub-part 111. A cable passage 400 is formed between the edge of the wire clamping portion 210 and the edge of another portion of the first sub-part 111. That is, the cable 300 passes through the side wall of the insulating inner shell 100 and extends out.

[0035] In this embodiment, the overall dimensions of the cable 300 and the insulating inner shell 100 are smaller in the direction of the center line of the insulating inner shell 100, resulting in a smaller size of the lamp. With this arrangement, the cable 300 does not occupy any additional space above the lamp. Therefore, when the lamp is mounted on the mounting base at the top, this wiring method helps to reduce the gap between the lamp and the mounting base, thereby improving the stability of the lamp.

[0036] In other alternative embodiments, the wire port 110 may also be integrally located on the top surface of the insulating inner shell 100.

[0037] In a further embodiment, referring to Figures 2 to 4, the wire passage 110 further includes a second sub-part 112, which is disposed on the top surface of the insulating inner shell 100. The insulating wire pressing member 200 further includes a mounting part 220, which is connected to the wire pressing part 210 and covers the second sub-part 112. The mounting part 220 is also connected to the insulating inner shell 100.

[0038] In this embodiment, due to the presence of the second sub-part 112, the cable passage 110 provides greater operating space for the cable 300 to be threaded through, thereby making the installation of the cable 300 more convenient. Furthermore, the mounting part 220 provides a connection basis for the connection between the wire clamping part 210 and the insulating inner shell 100, thereby making the connection between the insulating wire clamping part 200 and the insulating inner shell 100 more reliable.

[0039] In other alternative embodiments, the wire passage 110 may not include the second sub-section 112. In this case, the insulating crimping member 200 may, for example, not include the mounting section 220.

[0040] In a further embodiment, the mounting portion 220 is supported on the insulating inner shell 100, and the insulating crimping member 200 further includes a limiting portion 230, which is disposed on the mounting portion 220 and located in the inner cavity of the insulating inner shell 100. The insulating inner shell 100 is provided with a mating portion 120, and a part of the limiting portion 230 is located below the mating portion 120 and is upper-limitedly mated with the mating portion 120 in the direction of the center line of the insulating inner shell 100.

[0041] In this embodiment, the mounting part 220 is supported on the insulating inner shell 100. In this case, the insulating inner shell 100 can restrict the mounting part 220 from moving toward the bottom end of the insulating inner shell 100. At the same time, a part of the limiting part 230 is engaged with the mating part 120 in the direction of the center line of the insulating inner shell 100. The mating part 120 can restrict the mounting part 220 from moving toward the bottom end of the insulating inner shell 100, so that the mounting part 220 can be connected to the insulating inner shell 100.

[0042] Specifically, the limiting part 230 is provided with a limiting tooth 231, which is located below the mating part 120 and engages with the mating part 120 in the direction of the center line of the insulating inner shell 100.

[0043] In actual use, the limiting part 230 deforms so that the limiting tooth 231 avoids the mating part 120. When the mounting part 220 is supported on the insulating inner shell 100, the limiting tooth 231 moves past the position of the mating part 120 to below the mating part 120 and engages with the mating part 120 in the direction of the center line of the insulating inner shell 100, thereby connecting the mounting part 220 to the insulating inner shell 100. Therefore, in this embodiment, the connection between the mounting part 220 and the insulating inner shell 100 can be achieved without the aid of tools, thus reducing the installation difficulty of the insulating wire clamp 200.

[0044] In other alternative embodiments, the mounting portion 220 may also be connected to the insulating inner shell 100 via a first threaded connection.

[0045] In a further embodiment, referring to FIG8, the number of limiting portions 230 is, for example, two, including a first limiting portion 230a and a second limiting portion 230b, and the number of mating portions 120 is, for example, at least two, including a first mating portion 120a and a second mating portion 120b. The first limiting portion 230a and the second limiting portion 230b are both located between the first mating portion 120a and the second mating portion 120b, and respectively engage with the first mating portion 120a and the second mating portion 120b in the direction of the center line of the insulating inner shell 100. In other words, the first limiting portion 230a engages with the first mating portion 120a in the direction of the center line of the insulating inner shell 100, and the second limiting portion 230b engages with the second mating portion 120b in the direction of the center line of the insulating inner shell 100.

[0046] In addition, the first limiting part 230a and the first mating part 120a are mutually limiting in the first direction, and the second limiting part 230b and the second mating part 120b are mutually limiting in the first direction. The first direction, the center line direction of the insulating inner shell 100 and the length direction of the cable 300 are, for example, perpendicular to each other. Specifically, the first direction is, for example, the direction indicated by arrow line A in Figure 8, and the length direction of the cable 300 is, for example, the direction indicated by arrow line B in Figure 9.

[0047] In this embodiment, the insulating crimping member 200 and the insulating inner shell 100 are connected by at least two limiting portions 230, which improves the reliability of the connection between the insulating crimping member 200 and the insulating inner shell 100. Furthermore, in this embodiment, both the first limiting portion 230a and the second limiting portion 230b are located between the first mating portion 120a and the second mating portion 120b, with the first limiting portion 230a and the first mating portion 120a engaging in a limiting fit in the first direction, and the second limiting portion 230b and the second mating portion 120b engaging in a limiting fit in the first direction. This arrangement prevents the insulating crimping member 200 from moving in the first direction, thereby making the connection between the insulating crimping member 200 and the insulating inner shell 100 more reliable.

[0048] Alternatively, referring to Figures 5 and 8, when the insulating wire clamping member 200 includes only the first limiting part 230a and the second limiting part 230b, the mounting part 220, the first limiting part 230a, and the second limiting part 230b as a whole are, for example, generally inverted U-shaped.

[0049] Of course, in other optional embodiments, the number of limiting parts 230 may be one or at least three. In this embodiment, the number of limiting parts 230 is not limited. In other embodiments, the first limiting part 230a may also be located on the side of the first mating part 120a away from the second mating part 120b. Similarly, the second limiting part 230b may also be located on the side of the second mating part 120b away from the first mating part 120a.

[0050] In a further embodiment, referring to FIG3, the insulating inner shell 100 is provided with a support step 140, and the mounting part 220 is supported on the support step 140 and is at least partially located on the insulating inner shell 100. With this arrangement, the overall size of the insulating pressure member 200 and the insulating inner shell 100 is smaller in the direction of the centerline of the insulating inner shell 100, which is beneficial to reducing the size of the lamp.

[0051] In other alternative embodiments, the insulating crimping member 200 may also be located outside the insulating inner housing 100.

[0052] In a further embodiment, referring to Figures 3 and 5, the insulating wire clamping member 200 further includes a snap-fit ​​portion 240, which is disposed in the mounting portion 220 and located within the inner cavity of the insulating inner shell 100. The insulating inner shell 100 is provided with a limiting groove 130, the length direction of the limiting groove 130, the centerline direction of the insulating inner shell 100, and the length direction of the cable 300 intersect. Optionally, the length direction of the limiting groove 130, the centerline direction of the insulating inner shell 100, and the length direction of the cable 300 are, for example, perpendicular to each other, and at least a portion of the snap-fit ​​portion 240 is located in the limiting groove 130 and engages with the limiting groove 130 in a limiting engagement along the length direction of the cable 300. Optionally, the length direction of the limiting groove 130 is, for example, the same as the first direction mentioned above.

[0053] In this embodiment, the snap-fit ​​part 240 and the limiting groove 130 are engaged in a limiting fit along the length of the cable 300, thereby preventing the insulating wire clamp 200 from moving along the length of the cable 300. This makes the connection between the insulating wire clamp 200 and the insulating inner shell 100 more reliable and improves the pull-out resistance of the cable 300.

[0054] Optionally, the number of snap-fit ​​portions 240 may be at least two, for example, to further improve the connection reliability between the insulating crimping member 200 and the insulating inner shell 100. When the number of snap-fit ​​portions 240 is at least two, each snap-fit ​​portion 240 is arranged at intervals, for example, along the length direction of the limiting groove 130. Of course, in other embodiments, the number of snap-fit ​​portions 240 may also be one. In this embodiment, the number of snap-fit ​​portions 240 is not limited.

[0055] In an alternative embodiment, the insulating crimping member 200 may also exclude the snap-fit ​​portion 240.

[0056] In another embodiment, referring to Figures 3 and 8, the insulating inner shell 100 is provided with a positioning part 150, which is located in the inner cavity of the insulating inner shell 100 and has a positioning groove 151. The positioning groove 151 extends along the length direction of the cable 300, and the first end of the cable 300 passes through the positioning groove 151. The opening of the positioning groove 151 is disposed away from the top surface of the insulating inner shell 100, and the opening allows the cable 300 to enter and exit the positioning groove 151. With this configuration, the positioning groove 151 can restrict the movement of the cable 300 in the second direction and can restrict the movement of the cable 300 toward the top surface of the insulating inner shell 100, thereby improving the stability of the cable 300. The second direction, the centerline direction of the insulating inner shell 100, and the length direction of the cable 300 are, for example, perpendicular to each other, and the second direction is, for example, the same as the first direction mentioned above.

[0057] In other alternative embodiments, the insulating inner shell 100 may also omit the positioning portion 150.

[0058] In an optional embodiment, the insulating inner shell 100 may be provided with both the limiting portion 230 and the positioning portion 150 mentioned above. In this case, the limiting portion 230 and the positioning portion 150 engage in a limiting cooperation in the length direction of the cable 300. In this case, the movement of the limiting portion 230 in the length direction of the cable 300 is restricted, thereby further improving the stability of the insulating wire clamp 200.

[0059] In another embodiment, referring to Figures 1, 2, 7 and 11, the metal housing 500 is provided with a wire passage hole 510. The first insulating part 160 protrudes from the insulating inner housing 100 in a direction away from the inner cavity of the insulating inner housing 100, and the second insulating part 250 protrudes from the insulating wire clamping member 200 in a direction away from the inner cavity of the insulating inner housing 100. The first insulating part 160 and the second insulating part 250 together form an insulating sleeve. One end of the insulating sleeve is connected to the wire passage channel 400, and the other end passes through the wire passage hole 510. The first end of the cable 300 enters the wire passage channel 400 through the inner cavity of the insulating sleeve, and there is a gap between the insulating sleeve and the hole wall of the wire passage hole 510.

[0060] In this embodiment, the cable 300 passes through the insulating sleeve. This allows the insulating sleeve to separate the cable 300 from the cable through-hole 510 in the circumferential direction, further improving the safety of the lamp and reducing scratches on the cable 300. Furthermore, in this embodiment, there is a gap between the insulating sleeve and the wall of the cable through-hole 510. This results in a larger area of ​​the cable through-hole 510 in the direction perpendicular to its centerline, allowing both the insulating sleeve and the cable 300 to pass through the cable through-hole 510 more easily.

[0061] In other alternative embodiments, there may be no gap between the insulating sleeve and the wall of the wire hole 510, and the first insulating portion 160 and the second insulating portion 250 may not form an insulating sleeve. In this case, the first insulating portion 160 and the second insulating portion 250 may be arranged at intervals along the circumference of the cable 300, for example.

[0062] In one optional embodiment, the area of ​​the cavity on the metal outer shell 500 is larger than the area of ​​the insulating inner shell 100 in the direction perpendicular to the centerline of the insulating inner shell 100. This arrangement provides an installation space between the metal outer shell 500 and the insulating inner shell 100, thereby facilitating the assembly of the insulating inner shell 100 and the metal outer shell 500.

[0063] In the actual assembly process, for example, the center line of the insulating inner shell 100 is tilted relative to the center line of the metal outer shell 500, and in this state, the insulating inner shell 100 is gradually installed into the inner cavity of the metal outer shell 500. After the insulating inner shell 100 enters the inner cavity of the metal outer shell 500, for example, the center line of the insulating inner shell 100 is adjusted to be parallel or coincident with the center line of the metal outer shell 500, thereby completing the installation of the insulating inner shell 100.

[0064] Additionally, referring to Figure 9, the insulating inner shell 100 may be provided with a clearance portion 190, which is used to avoid the metal outer shell 500 to prevent the insulating inner shell 100 from colliding with the metal outer shell 500 during the process of entering the inner cavity of the metal outer shell 500.

[0065] In a further embodiment, the cable 300 and the insulating sleeve are interference-fitted. This configuration ensures a tighter fit between the cable 300 and the insulating sleeve, thereby improving the sealing performance of the lamp. Furthermore, this configuration generates a greater force between the cable 300 and the insulating sleeve, thus enhancing the pull-out resistance of the cable 300.

[0066] In other alternative embodiments, the cable 300 and the insulating sleeve may also be clearance-fitted or transition-fitted.

[0067] In another embodiment, referring to Figures 10 and 11, the metal outer shell 500 and the insulating inner shell 100 are snap-fitted together. This configuration allows for the assembly and disassembly of the metal outer shell 500 and the insulating inner shell 100 without the need for tools, thus making their assembly and disassembly more convenient.

[0068] Optionally, the metal outer shell 500 may be provided with a locking hole 520, and the insulating inner shell 100 may be provided with a locking tooth 180. The locking tooth 180 engages with the locking hole 520 to achieve the engagement of the metal outer shell 500 and the insulating inner shell 100.

[0069] In other alternative embodiments, the metal outer shell 500 and the insulating inner shell 100 may also be connected by a second threaded connection.

[0070] In one optional embodiment, the insulating inner shell 100 is, for example, a one-piece structure, and for example, a plastic inner shell. In this case, the first insulating portion 160, the mating portion 120 mentioned above, and the positioning portion 150 mentioned above are all, for example, part of the insulating inner shell 100. With this arrangement, the connection strength between the first insulating portion 160, the mating portion 120, and the positioning portion 150 and the insulating inner shell 100 is high, thereby extending the service life of the lamp.

[0071] In one optional embodiment, the insulating wire clamp 200 is, for example, a one-piece structure and, for example, a plastic wire clamp. In this case, the second insulating portion 250 and the aforementioned limiting portion 230 are both, for example, part of the insulating wire clamp 200. With this configuration, the connection strength between the second insulating portion 250 and the limiting portion 230 and the insulating wire clamp 200 is high, thereby also extending the service life of the lamp.

[0072] In another embodiment, referring to Figures 9 and 10, the lamp further includes a circuit board 600 disposed within the cavity of the insulating inner shell 100 and electrically connected to the first end of the cable 300. The insulating inner shell 100 is provided with a heat-fused component 170. Optionally, the heat-fused component 170 may be, for example, a heat-fused pillar. One end of the heat-fused component 170 passes through the circuit board 600 along its thickness direction and has an anti-detachment portion heat-fused thereto. The anti-detachment portion engages with the circuit board 600 in the thickness direction of the circuit board 600, for example, the same as the centerline direction of the insulating inner shell 100. The heat-fused method can be automated, thereby saving manpower. In addition, in this embodiment, the anti-detachment portion is formed from a portion of the heat-fused component 170, which makes the connection strength between the anti-detachment portion and the heat-fused component 170 higher, thereby reducing the probability of the circuit board 600 falling off.
