Description

Lamp fixing seat and lamp connecting seat

Technical Field

Embodiments of the present disclosure relate generally to the field of lighting devices, and more particularly, to a lamp fixing base, a lamp connecting base, a lamp including the lamp connecting base, and a lamp assembly including the lamp fixing base and the lamp.

Background

Conventional lighting devices (e.g., ceiling lights) are typically mounted to a mounting location (e.g., a roof or ceiling) using screws or expansion bolts or the like. Such installation typically requires the operation of a professional. In the operation process, the lampshade needs to be detached firstly, then the lamp body is fixed by using screws or expansion bolts and the like, then the wires are connected to corresponding joints of the lamp, and finally the lampshade is covered again. The operation process is very inconvenient and the efficiency is low. One solution that has been proposed is to preset a lamp holder at a mounting location such as a roof or ceiling, then mount a lamp including a connection socket to the lamp holder through the connection socket, and complete mechanical and electrical connection.

For the lamp mounting structure, a user usually needs to rotate the lamp connecting seat relative to the lamp fixing seat in the mounting process. After the lamp connecting seat is rotated to the proper position, the user needs to lock the lamp connecting seat, so that the lamp connecting seat can not rotate relative to the lamp fixing seat. Existing locking means include, for example, a user fixing the light fixture attachment socket by manually tightening screws or bolts or the like. Similarly, in the case where the user wants to replace the lamp and needs to separate the lamp attachment socket from the lamp attachment base, an operation of manually loosening the screw or bolt is also required.

Furthermore, once the installation is completed, the orientation of the fixture mount is fixed, and thus the orientation of the fixture is also fixed. If the user wishes to adjust the orientation of the light fixture, the light fixture mount has to be removed from the installation location and reinstalled according to the desired orientation of the light fixture. The above-described removal and reinstallation process is cumbersome.

SUMMERY OF THE UTILITY MODEL

Embodiments of the present disclosure provide a lamp fixing seat, a lamp connecting seat, a lamp including the lamp connecting seat, and a lamp assembly including the lamp fixing seat and the lamp, so as to at least partially solve the above problems in the prior art.

In one aspect of the present disclosure, a luminaire holder is provided. This lamps and lanterns fixing base includes: a body extending about a first axis and including first and second ends opposite along the first axis; the mounting part protrudes outwards from the edge of the first end of the main body and is suitable for keeping the lamp fixing seat at a mounting position; the projection is arranged on the outer side of the second end of the main body and is suitable for supporting a lamp connecting seat matched with the lamp fixing seat; and the first rotation limiting mechanism is suitable for protruding into at least one part of the corresponding rotation limiting mechanism of the lamp connecting seat along the direction of the first shaft under the state that the lamp connecting seat is supported on the lamp fixing seat so as to prevent the lamp connecting seat from rotating relative to the lamp fixing seat.

According to the embodiment of the present disclosure, the lamp fixing seat is matched with a corresponding rotation limiting mechanism (hereinafter also referred to as "second rotation limiting mechanism") on the lamp connecting seat through a rotation limiting mechanism (i.e., a first rotation limiting mechanism) of the lamp fixing seat, so that the purpose of preventing the lamp connecting seat (i.e., a lamp including the lamp connecting seat) from rotating relative to the lamp fixing seat after the installation of the lamp is completed is achieved. With such a lamp mounting structure, the above-described process of manually screwing or unscrewing the screws or bolts can be omitted during the process of mounting and demounting the lamp, thereby simplifying the mounting and demounting steps.

In some embodiments, the lamp holder may further include a holder bottom disposed at the second end of the main body; wherein the projection protrudes outwardly from an edge of the holder bottom, and the first rotation limiting mechanism may be formed as a first contour on a surface of the projection opposite to the holder bottom, the first contour being adapted to protrude into at least a portion of a corresponding contour of the lamp attachment socket in a state where the lamp attachment socket is supported on the lamp attachment holder. In this way, during installation of the luminaire, a user may temporarily separate the first profile from a corresponding profile (hereinafter also referred to as "second profile") of the luminaire-connecting socket by lifting the luminaire, and rotate the luminaire (i.e. the luminaire-connecting socket) into position. Then, the user only needs to put down the lamp (namely, the lamp connecting seat), so that the second contour of the lamp connecting seat falls on the first contour of the bump of the lamp fixing seat, and the second contour is matched with the first contour, so that the lamp connecting seat can be locked.

In some embodiments, the length of the corresponding profile (i.e., the second profile) may be 1.5 to 5 times the length of the first profile in a circumferential direction around the first shaft. In embodiments of the present disclosure, the first axis generally refers to a rotation axis of the body of the lamp holder. Since the length of the second profile is greater than the length of the first profile, the first profile can mate with different portions of the second profile. In this way, the luminaire connection socket and the luminaire comprising the luminaire connection socket may be positioned in different orientations in a circumferential direction around the first axis. That is, the mounting orientation of the light fixture attachment socket and the light fixture is adjustable over a range of angles (e.g., over a range of 45 degrees). Such an arrangement facilitates a user to conveniently adjust the orientation of the light fixture as desired without having to remove and reinstall the light fixture mount from the installed position.

In some embodiments, the lamp holder may further include a holder bottom disposed at the second end of the main body; the first rotation limiting mechanism may be formed as an elastic pin provided in the bottom of the fixing base, the elastic pin being adapted to extend into a corresponding hole on the lamp connecting base by means of an elastic force in a state where the lamp connecting base is supported on the lamp fixing base, so as to prevent the lamp connecting base from rotating relative to the lamp fixing base. The arrangement realizes the locking of the lamp connecting seat by utilizing the elastic pin and the corresponding hole, thereby saving the process of manually screwing the screw or the bolt in the prior art and simplifying the installation process.

In some embodiments, an opening adapted for the first snap electrical connection terminal of the power cord to pass through may also be provided in the base of the holder. In this way, the first buckle electrical connection terminal of the power cord can conveniently pass out of the opening, and can be connected with the corresponding electrical connection terminal on the lamp, so that the electrical connection of the lamp is conveniently realized.

In another aspect of the present disclosure, a light fixture connection socket is provided. The lamp connecting seat is suitable for being matched with the lamp fixing seat according to the aspect. This lamps and lanterns connecting seat includes: the main body is provided with an accommodating cavity for accommodating the main body of the lamp fixing seat around the second shaft; and a second rotation limiting mechanism adapted to receive the first rotation limiting mechanism of the lamp fixing seat protruding into at least a part of the second rotation limiting mechanism in the direction of the second shaft in a state where the lamp connecting seat is supported in the lamp fixing seat, so as to prevent the lamp connecting seat from rotating relative to the lamp fixing seat.

As described above, according to the embodiments of the present disclosure, the lamp connecting socket is matched with the first rotation limiting mechanism of the lamp fixing base through the second rotation limiting mechanism of the lamp connecting socket, so that the purpose of preventing the lamp connecting socket (i.e., the lamp including the lamp connecting socket) from rotating relative to the lamp fixing base after the lamp is installed is achieved. With such a lamp mounting structure, the above-described process of manually screwing or unscrewing the screws or bolts can be omitted during the process of mounting and demounting the lamp, thereby simplifying the mounting and demounting steps.

In some embodiments, the bottom side of the main body may be provided with a fixing seat matching portion located at the periphery of the accommodating cavity and adapted to be supported by the projection of the lamp fixing seat; wherein the second rotation limiting mechanism may be formed as a second contour on a surface of the holder fitting portion, the second contour being adapted to receive at least a portion of the first contour in a state where the lamp connecting holder is supported on the lamp holder. As described above, the first profile and the second profile are fitted to each other, thereby conveniently achieving locking of the lamp (i.e., the lamp-connecting socket).

In some embodiments, the length of the second profile may be 1.5 to 5 times the length of the first profile in a circumferential direction about the second axis. In the embodiments of the present disclosure, the second axis generally refers to a rotation axis of the main body of the lamp connecting base. As described above, since the length of the second profile is greater than the length of the first profile, the installation orientation of the light fixture attachment socket and the light fixture is adjustable within a certain angular range (e.g., within a range of 45 degrees).

In some embodiments, the lamp connecting base may further include a receiving cavity bottom, wherein the second rotation limiting mechanism may be formed as a positioning hole provided in the receiving cavity bottom, such that the elastic pin of the lamp fixing base is adapted to protrude into the positioning hole by means of an elastic force in a state where the lamp connecting base is supported on the lamp fixing base, to prevent the lamp connecting base from rotating relative to the lamp fixing base. As described above, such an arrangement realizes locking of the lamp attachment socket using the elastic pin and the corresponding hole, thereby eliminating the existing process of manually tightening a screw or bolt and simplifying the installation process.

In some embodiments, an opening suitable for the first snap electric connection terminal of the power cord to pass through can be further arranged in the bottom of the accommodating cavity; and the light fixture connection socket may further include a second snap electrical connection terminal adapted to couple with the first snap electrical connection terminal of the power cord. In this way, the first snap electrical connection terminal of the power cord can be conveniently passed out of the opening. Furthermore, by coupling the first and second electrical connection terminals, electrical connection of the luminaire can be conveniently achieved.

In yet another aspect of the present disclosure, a light fixture is provided. The lamp comprises a lamp body and the lamp connecting base according to the aspect.

In some embodiments, the light fixture body and the light fixture attachment socket are integrally formed.

In yet another aspect of the present disclosure, a light fixture assembly is provided. The lamp assembly comprises the lamp fixing base according to the above aspect and the lamp according to the above aspect.

Detailed Description

The present disclosure will now be described with reference to several example embodiments. It should be understood that these examples are described only for the purpose of enabling those of ordinary skill in the art to better understand and thereby enable the present disclosure, and are not intended to set forth any limitations on the scope of the presently disclosed technology.

As used herein, the term "include" and its variants are to be read as open-ended terms meaning "including, but not limited to. The term "based on" will be read as "based at least in part on". The terms "one embodiment" and "an embodiment" should be understood as "at least one embodiment". The term "another embodiment" should be understood as "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions may be included below. The definitions of the terms are consistent throughout the specification unless the context clearly dictates otherwise.

As already briefly mentioned above, the inventor has noted that, in the prior art, after the installation of the lamp, the screw or bolt or the like needs to be manually tightened to prevent the lamp connecting seat from rotating relative to the lamp fixing seat. This causes inconvenience in the installation of the lamp. Further, once installation is complete, the orientation of the light fixture is fixed. To adjust or change the orientation of the light fixture, the user must remove the light fixture from the light fixture mount and remove the light fixture mount from the installed position, and then reinstall the light fixture mount according to the desired orientation of the light fixture. Because a user cannot accurately determine the orientation of the lamp after the lamp is mounted on the lamp holder according to the orientation of the lamp holder when the lamp holder is mounted, the mounting and dismounting processes of the lamp holder may be repeated many times. Such problems are particularly acute for polygonal luminaires such as square or rectangular, as users often desire that the mounting orientation of the luminaire be able to fit the shape of the room (e.g. four sides of a square luminaire are parallel to four walls of the room respectively).

Based on the above recognition, a lamp fixing seat and a lamp connecting seat which are convenient to install and replace are provided. In general, the lamp holder and the lamp connecting socket lock the lamp connecting socket after installation using a cooperating rotation limiting mechanism to prevent the lamp connecting socket (i.e., the lamp including the lamp connecting socket) from rotating relative to the lamp holder. Furthermore, the user is also able to adjust the orientation of the light fixture attachment socket and the light fixture including the light fixture attachment socket within a range without having to remove the light fixture from the light fixture mount and/or remove the light fixture mount from an installed position. Therefore, the lamp fixing seat and the lamp connecting seat in the embodiment of the disclosure have good adaptability. Some example embodiments of the present disclosure will be described in detail below with reference to fig. 1A to 8.

In one embodiment, as shown in fig. 1A and 1B, the luminaire-fixing base 10 includes a main body 11. The body 11 extends around a first axis X. In the embodiment of the present disclosure, the first axis X generally refers to a rotation axis of the main body 11 of the lamp holder 10. The lamp holder 10 further includes a first end 12 and a second end 13 opposite to each other along the first axis X. When fixing the luminaire fixture 10 to a mounting location, such as a ceiling, the first end 12 will be close to the mounting location, while the second end 13 will be remote from the mounting location.

In order to fix the lamp fixing base 10 to the mounting position, a mounting portion 14 is formed at an edge of the first end 12 of the main body 11 to protrude outward. The mounting portion 14 may be fixed to a mounting position by, for example, a screw or a bolt. In one embodiment, as shown in fig. 1A and 1B, the number of mounting portions 14 is 4. The 4 mounting portions 14 provided on the lamp holder 10 facilitate the orientation of a lamp (e.g., a square lamp). In other embodiments, more or fewer mounting portions 14 may be provided on the body 11, such as 2, 3, 5, etc., as the scope of the present disclosure is not limited in this respect.

The outer side of the second end 13 of the main body 11 is provided with a projection 15 for supporting the lamp connecting socket. In one embodiment, as shown in fig. 1A and 1B, the number of bumps 15 is 4. In other embodiments, more or fewer lugs 15 may be provided on body 11, such as 2, 3, 5, etc., as the scope of the present disclosure is not limited in this respect. In the present disclosure, "outside" may refer to a case where the bump 15 is directly connected to the second end 13 of the body 11 as shown in fig. 1A and 1B. Furthermore, as will be described in detail below, "outboard" may also refer to the case where the tab is spaced from the body and located outside the body in the radial direction of the first axis X.

In addition, fig. 2 shows an embodiment of a lamp connecting socket 20 for use with the lamp fixing socket 10. The light fixture attachment socket 20 includes a body 21. The body 21 has an axis of revolution Y (also referred to herein as the "second axis"). A flange 22 extending in the direction of the second axis Y may be provided at the periphery of the main body 21. The flange 22 may be used to connect with a lamp housing (not shown in fig. 2) or the like of a light fixture. The main body 21 is provided with a receiving cavity 23 around the second axis Y for receiving the main body 11 of the lamp holder 10.

Referring again to fig. 1A and 1B in conjunction with fig. 2, to achieve locking of the fixture attachment socket 20 after installation of the fixture is complete, thereby preventing rotation of the fixture attachment socket 20 relative to the fixture mount 10, the fixture mount 10 further includes a first rotation limiting mechanism. Accordingly, the light fixture attachment socket 20 further includes a second rotation limiting mechanism that cooperates with the first rotation limiting mechanism. In general, the first rotation limiting mechanism can protrude into at least a portion of the second rotation limiting mechanism of the lamp connecting base 20 in a direction of the first axis X (i.e., the second axis Y in a state where the lamp connecting base 20 is supported on the lamp fixing base 10, because the first axis X coincides with the second axis Y in this state) to prevent the lamp connecting base 20 from rotating relative to the lamp fixing base 10. In this way, during installation of the light fixture, the user need only rotate the light fixture (including the light fixture attachment receptacle 20 on the light fixture) to the desired orientation, and then set down the light fixture. Thus, the lamp connecting socket 20 will be supported on the lamp fixing base 10, and the first rotation limiting mechanism cooperates with the second rotation limiting mechanism, so as to prevent the lamp connecting socket 20 from rotating relative to the lamp fixing base 10. The above process omits the step of manually tightening a screw or bolt to fix the lamp-connecting socket 20, thereby simplifying the installation process.

It should be appreciated that in various embodiments, the first and second rotation limiting mechanisms may be implemented in various suitable forms. Several example embodiments will be described below. However, the illustrative descriptions in the following embodiments for the specific forms of the first rotation restricting mechanism and the second rotation restricting mechanism do not constitute limitations on the composition and structure of the present disclosure. Other forms of structures may be contemplated by those of ordinary skill in the art in view of the teachings of the present disclosure.

In some embodiments, such as shown in fig. 1A and 1B, the luminaire mount 10 may further include a mount bottom 16. The anchor base 16 is disposed at the second end 13 of the main body 11. The projection 15 projects outwardly from the edge of the holder base 16. In this arrangement, the first rotation limiting mechanism may be formed as a contour 17 (also referred to herein as a "first contour") on a surface of the boss 15 opposite the mount base 16. In addition, an electrical connector 18 may be further disposed at a central position of the fixing base bottom 16 for electrically connecting with a corresponding electrical connector on the lamp.

Corresponding to the above structure, in some embodiments, for example, as shown in fig. 2, the bottom side of the main body 21 of the luminaire connection base 20 may be provided with a fixing base mating portion 24 located at the periphery of the receiving cavity 23. The holder fitting portion 24 can be supported by the projection 15 of the lamp holder 10, so that the lamp attachment holder 20 is supported on the lamp holder 10. As shown in fig. 2, the holder engagement portion 24 includes 4 segments, and the 4 segments are spaced around the second axis Y at the periphery of the receiving cavity 23. Between the 4 segments of the holder fitting portion 24, a notch 25 is formed.

With respect to the lamp fixing base 10 and the lamp connecting base 20, the installation of the lamp can be performed as follows:

(1) fixing the lamp fixing seat 10 at the installation position;

(2) the user lifts the luminaire (which generally includes the luminaire-coupling socket 20) and aligns the notch 25 of the luminaire-coupling socket 20 with the projection 15 of the luminaire-coupling socket 10;

(3) pushing the lamp into the lamp fixing seat 10 in a direction to allow the main body 11 of the lamp fixing seat 10 to enter the accommodating cavity 23 of the lamp connecting seat 20;

(4) rotating the lamp (and rotating the lamp connecting seat 20 on the lamp at the same time) so that the fixing seat matching part 24 of the lamp connecting seat 20 aligns with the bump 15 of the lamp fixing seat 10;

(5) putting down the lamp to make the fixing seat matching part 24 of the lamp connecting seat 20 fall on the bump 15 of the lamp fixing seat 10, thereby completing the connection of the lamp (namely the lamp connecting seat 20) and the lamp fixing seat 10;

(6) depending on the specific structure of the lamp, operations such as mounting the light emitting component, electrical connection, and mounting the lamp cover may be required.

It should be appreciated that while an embodiment in which the anchor block mating portion 24 includes 4 segments is shown in fig. 2, in other embodiments, the anchor block mating portion 24 may include more or fewer segments, such as 2, 3, 5, etc., as the scope of the present disclosure is not limited in this respect. In general, the number of segments of the holder engagement portion 24 may correspond to the number of the projections 15 of the lamp holder 10.

In such an arrangement, the second rotation limiting mechanism of the fixture-connecting socket 20 may be formed as a contour 26 (also referred to herein as a "second contour") on a surface of the fixture-mating portion 24. Thus, in a state where the holder fitting portion 24 of the lamp attachment holder 20 is supported on the projection 15 of the lamp attachment holder 10, the first contour 17 can protrude into at least a portion of the second contour 26 of the lamp attachment holder 20, thereby achieving locking of the lamp attachment holder 20.

It should be understood that although fig. 1A, 1B and 2 show the first profile 17 and the second profile 26 as saw-tooth-like profiles, the first profile 17 and the second profile 26 may also be realized in various suitable forms. For example, first profile 17 and second profile 26 may be formed as triangular teeth, square teeth, trapezoidal teeth, curvilinear teeth, or various combinations of the above types of profiles, although the scope of the present disclosure is not limited in this respect.

In some embodiments, as shown in fig. 1A, 1B and 2, for example, in a circumferential direction around the first axis X (or the second axis Y), a length L2 of the second profile 26 of the lamp connecting socket 20 may be greater than a length L1 of the first profile 17 of the lamp fixing socket 10, for example, the length L2 may be 1.5 to 5 times the length L1. In this way, the first profile 17 can cooperate with different portions of the second profile 26 in a circumferential direction around the first axis X (or the second axis Y). Thus, in a circumferential direction around the first axis X (or the second axis Y), the fixture attachment socket 20 and the fixture including the fixture attachment socket 20 may be positioned in different orientations such that the mounting orientation of the fixture attachment socket 20 and the fixture is adjustable within a certain angular range (e.g., within a range of 45 degrees). Such an arrangement facilitates a user to conveniently adjust the orientation of the light fixture according to actual needs without removing and reinstalling the light fixture 10 from the installation position.

For example, for a square or rectangular lamp, a user may first adjust the orientation of the lamp holder 10 approximately by visual observation and fix the lamp holder 10 in the installation position. The user can then rotate the light fixture (including the light fixture attachment socket 20 on the light fixture) so that the four sides of the light fixture are parallel to the four walls of the room. Subsequently, the user may support the second contour 26 of the lamp connecting socket 20 on the first contour 17 of the lamp fixing base 10, thereby completing the connection of the lamp connecting socket 20 and the lamp fixing base 10. It can be seen that the above structure provides a user with a solution to conveniently adjust the orientation of the light fixture (including the light fixture attachment socket 20 on the light fixture) without having to repeatedly remove and reinstall the light fixture 10.

Fig. 3 and 4 schematically illustrate a luminaire assembly 100 according to one embodiment of the present disclosure. The lamp assembly 100 includes a lamp holder 10 and a lamp connecting socket 20. The lamp assembly 100 further includes an inner housing 50 coupled to the lamp coupling socket 20. Inner housing 50 includes an electrical connector 51. The electrical connector 51 may be electrically connected with the electrical connector 18 of the lamp holder 10. The luminaire assembly 100 further comprises a light emitting assembly 60. Light assembly 60 may be secured to inner housing 50 and include a light emitting element such as an LED. Further, the lamp assembly 100 further comprises a lamp housing 70. The lamp housing 70 may be fixed to the lamp connecting socket 20. In such an arrangement, the light fixture attachment socket 20, the inner housing 50, the light emitting assembly 60 and the lamp shade 70 form a light fixture. When the lamp is installed, a user may fix the lamp fixing base 10 to an installation location (e.g., a roof or a ceiling), and then fix the lamp to the lamp fixing base 10 through the lamp connecting base 20, so as to install the lamp. It should be understood that although in fig. 3 and 4, light fixture attachment socket 20 and inner housing 50 are separate components, in other embodiments, light fixture attachment socket 20 and inner housing 50 may be integrally formed.

In other embodiments, the rotation limiting mechanism may be implemented in other forms, for example, as shown in fig. 5-8. As shown in fig. 5, the lamp fixing base 30 includes a main body 31. The body 31 extends around a first axis X. The body 31 has a first end 32 and a second end 33 opposite along a first axis X. When fixing the luminaire fixture 30 to a mounting location, such as a ceiling, the first end 32 will be close to the mounting location, while the second end 33 will be remote from the mounting location.

An edge of the first end 32 of the main body 31 is formed with a mounting portion 34 protruding outward. In this embodiment, the mounting portion 34 is formed in a substantially circular configuration. A plurality of mounting holes are provided in the mounting portion 34. Fasteners, such as screws 39, pass through the mounting holes to secure the mounting portion 34 in a mounted position. As shown in FIG. 5, the mounting portion 34 further includes an extension 34-1 extending in a direction along the first axis X toward the second end 33. At the end of the extension 34-1, a projection 35 is provided which projects radially outwardly along the first axis X. The projection 35 is spaced apart from the main body 31 and is disposed at a position radially outward of the first axis X with respect to the second end 33 of the main body 31. It should be understood that the tab 35 may alternatively be directly connected to the second end 33 of the body 31.

Fig. 6 shows an embodiment of a lamp attachment socket 40 for use with the lamp attachment socket 30 described above. The light fixture coupling socket 40 includes a body 41. The body 41 has a second axis Y. A flange 42 extending in the direction of the second axis Y may be provided at the periphery of the main body 41. The flange 42 may be used to connect with a lamp housing (not shown in fig. 6) or the like of a light fixture. The main body 41 is provided with a receiving cavity 43 around the second axis Y for receiving the main body 31 of the lamp holder 30. The body 41 may be provided with a projection 44 at the periphery of the receiving cavity 43. The lugs 44 may include a plurality of segments and are spaced apart along the perimeter of the receiving cavity 43. The projection 44 projects radially inwardly of the second axis Y.

For the lamp fixing seat 30 and the lamp connecting seat 40, the installation of the lamp can be performed as follows:

(1) fixing the lamp fixing seat 30 at the installation position;

(2) a user lifts the light fixture (which typically includes fixture attachment socket 40) and aligns portions between the plurality of segments of tab 44 of fixture attachment socket 40 with tab 35 of fixture attachment socket 30;

(3) pushing the lamp into the lamp fixing seat 30 in a direction to make the main body 31 of the lamp fixing seat 30 enter the accommodating cavity 43 of the lamp connecting seat 40;

(4) rotating the lamp (and rotating the lamp connecting seat 40 on the lamp) so that the projection 44 of the lamp connecting seat 40 aligns with the projection 35 of the lamp fixing seat 30;

(5) the lamp is put down, so that the projection 44 of the lamp connecting seat 40 falls on the projection 35 of the lamp fixing seat 30, and the connection between the lamp (namely the lamp connecting seat 40) and the lamp fixing seat 30 is completed;

(6) depending on the specific structure of the lamp, operations such as mounting the light emitting component, electrical connection, and mounting the lamp cover may be required.

Referring again to fig. 5, in this embodiment, the light fixture mount 30 may further include a mount bottom 36. A mount base 36 is provided at the second end 33 of the body 31. In such an arrangement, the first rotation limiting mechanism may be formed as a resilient pin 37 provided in the holder base 36. Accordingly, as shown in fig. 6, the light fixture coupling socket 40 may further include a receiving cavity bottom 45. The second rotation restricting mechanism may be formed as a positioning hole 46 provided in the housing chamber bottom 45. In this way, in the case of rotating the lamp attachment socket 40 to the position during the installation of the lamp, the elastic pin 37 can be inserted and engaged in the positioning hole 46 of the lamp attachment socket 40 by means of an elastic force, thereby preventing the lamp attachment socket 40 from rotating with respect to the lamp fixing base 30 in a state where the lamp attachment socket 40 is supported on the lamp fixing base 30. It can be seen that, in such an arrangement, when the lamp connecting socket 40 is rotated to the position (the projection 44 of the lamp connecting socket 40 is aligned with the projection 35 of the lamp fixing socket 30), the elastic pin 37 can automatically extend into and snap into the positioning hole 46 of the lamp connecting socket 40 by means of the elastic force, thereby eliminating the existing process of manually tightening screws or bolts and simplifying the installation process.

In some embodiments, such as shown in fig. 5-7, the light fixture mount 30 may also be provided with an opening 38 in the mount bottom 36 for the first snap electrical connection terminal 91 of the power cord 90 to pass through. Correspondingly, the lamp connecting socket 40 may further be provided with an opening 47 in the bottom 45 of the receiving cavity for the first snap electric connection terminal 91 of the power cord 90 to pass through. In addition, fixture attachment socket 40 may further include a second snap electrical connection terminal 92. In a state where the lamp connecting socket 40 is supported on the lamp fixing socket 30, a user may electrically connect the first and second snap electrical connection terminals 91 and 92, thereby conveniently achieving electrical connection of the lamp.

Fig. 8 schematically illustrates a luminaire assembly 200 according to another embodiment of the present disclosure. The lamp assembly 200 includes a lamp holder 30 and a lamp connecting socket 40.
