DETAILED DESCRIPTION

In order to make objectives, technical details of the examples of the present disclosure apparent, the technical solutions of the examples of the present disclosure will be described in a clearly and fully understandable way in connection with the specific examples and related drawings of the present disclosure. Apparently, the described examples are just part but not all of the examples of the present disclosure. Based on the described examples of the present disclosure herein, those skilled in the art can obtain other example(s), without any inventive work, which should be within the scope of the present disclosure.

DESCRIPTION OF REFERENCE NUMERALS IN THE DRAWINGS

The technical solutions disclosed by the respective examples of the present disclosure are described in detail below in conjunction with the accompanying drawings.

As illustrated inFIG. 1, an example of the present disclosure discloses a lamp, and the lamp can be used as a wall-wash lamp, a strip lamp, etc. The lamp includes a mounting base100and a lighting assembly200. The lamp may have a plurality of light assemblies200which are detachably mounted on the mounting base100and arranged in an array. Moreover, when the lighting assembly200is mounted on the mounting base100, the lighting assembly200and the mounting base100are electrically connected. The mounting base100may include at least one mounting portion110. The lighting assembly200is specifically mounted on the mounting portion110. Further, at least two mounting portions110are provided and spaced apart from each other at a preset interval, so as to allow more lighting assemblies200to be mounted. The preset interval may be flexibly determined depending on factors such as practical installation space. The mounting portion110may have a plate-like structure, and certainly may have any other suitable structure as long as the installation of the lighting assembly200can be achieved.

As illustrated inFIG. 8toFIG. 12, in addition to the mounting portion110, the mounting base100further includes a plurality of first electrical terminals150fixed on the mounting portion110. As illustrated inFIG. 2toFIG. 7, the lighting assembly200described above may specifically include a base210, a light-emitting device220, and an optical device230. The light-emitting device220and the optical device230are both mounted on the base210. The base210is detachably mounted on the mounting base100. After power on, the light-emitting device220can emit light, and the optical device230can change parameters such as the direction and intensity of the light emitted by the light-emitting device220based on the principles of reflection, refraction, etc. of light, which may provide satisfactory luminous effect of the entire lamp against the user demand. The light-emitting device220may include a second electrical terminal223. The plurality of first electrical terminals150on each mounting portion110are in plug-in fit with second electrical terminals223of a plurality of lighting assemblies200in one-to-one correspondence, so as to supply power to the lighting assemblies200.

In the lamp provided by the examples of the present disclosure, the plurality of lighting assemblies200are provided, and the mounting base100may be in detachable connection with the plurality of lighting assemblies200. Thus, the effect of enhancing the luminous intensity of the lamp can be achieved by increasing the number of the lighting assemblies200, thereby satisfying the user demand on lighting, especially the user demand on lighting in a large space. Moreover, the mounting base100is in detachable connection with each lighting assembly200and supplies power to the lighting assembly200by means of plug-in connection between the first electrical terminal150and the second electrical terminal223. As such, different lighting assemblies200can be flexibly selected and combined in accordance with different lighting requirements, so as to better meet the user demand on lighting. In addition, the plug-in connection between the first electrical terminal150and the second electrical terminal223may contribute to positioning to a certain extent, so that the mounting base100and the lighting assembly200of the lamp can be installed more rapidly.

In this example of the present disclosure, the mounting portion110may be provided in a strip-shaped structure. The plurality of first electrical terminals150are sequentially mounted in the extending direction of the mounting portion110, so as to allow the plurality of lighting assemblies200to be mounted. With the strip-shaped structure, the extending direction of the mounting portion110is identical to the length direction of the mounting portion110. The mounting portion110may have a plurality of positions for mounting the lighting assemblies200, and these positions may be distributed uniformly, so that the plurality of lighting assemblies200can be uniformly mounted on the mounting portion110. As such, the plurality of lighting assemblies200mounted on the same mounting portion110may have an identical installation height, thus enhancing the luminous effect of the lamp on one hand and providing more aesthetically pleasing appearance on the other hand. In addition, with such a structure, the length of the mounting portion110may be chosen flexibly in accordance with actual user demand, so as to allow different number of lighting assemblies200to be mounted, and therefore, the lamp has better scalability.

The mounting portion110and the lighting assembly200may be installed together by means of bolted-on connection, riveting, clamped connection, etc. To guarantee the installation reliability of the lighting assembly200on the mounting portion110and further to facilitate the mounting manipulation, clamped connection is preferred between the lighting assembly200and the mounting portion110in this example of the present disclosure.

Further, the structure for realizing the clamped connection between the lighting assembly200and the mounting portion110may be in numerous forms. For example, a snap-fit column may be provided on the lighting assembly200, while a snap-fit hole is provided in the mounting portion110, and the clamped connection between the lighting assembly200and the mounting portion110can be achieved by means of fitting between the snap-fit column and the snap-fit hole. In this example of the present disclosure, as illustrated inFIG. 8toFIG. 12, snap-fit protrusions111are provided on two opposite outer sides of the mounting portion110, and the lighting assembly200is clamped on the snap-fit protrusions111. Compared with holes, the snap-fit protrusions111provided on the side surfaces of the mounting portion110may lead to enhanced structural strength of the mounting portion110, so that the mounting portion110is not prone to deformation and thus would not have adverse influence on the appearance, luminous effect, etc. of the lamp.

Alternatively, a plurality of snap-fit protrusions111may be provided on the side surface of the mounting portion110, the snap-fit protrusions111are arranged in the extending direction of the mounting portion110, and each lighting assembly200is in snap fit with the corresponding snap-fit protrusion111. Certainly, the snap-fit protrusion111may be provided in a strip-shaped structure as well. That is, the snap-fit protrusion111extends in the extending direction of the mounting portion110, and the plurality of lighting assemblies200mounted on the same mounting portion110are all in snap fit with the same snap-fit protrusion111. Since the snap-fit protrusions111of a single mounting portion110are at the same height throughout, the plurality of lighting assemblies200mounted on the mounting portion110can be retained at the identical height more reliably, thereby improving the appearance and the luminous effect of the lamp.

The base210of the lighting assembly200may include a base body211, and a first elastic sheet212and a second elastic sheet213that are mounted on the base body211. The light-emitting device220and the optical device230are both mounted on the base body211. The first elastic sheet212and the second elastic sheet213are arranged opposite and clamped on the snap-fit protrusions111on two opposite outer sides of the mounting portion110, respectively. The first elastic sheet212and the second elastic sheet213both have a certain degree of elasticity and may undergo elastic deformation when being acted upon by an external force, thus giving rise to a trend of deformation recovery in which an acting force on the mounting portion110may be caused.

Specifically, when the lighting assembly200is assembled, the first elastic sheet212and the second elastic sheet213are first brought into contact with the mounting portion110, and then an external force is applied on the lighting assembly200, which causes the first elastic sheet212and the second elastic sheet213to deform under the force and thus slide relative to the mounting portion110until the first elastic sheet212and the second elastic sheet213are clamped with the snap-fit protrusions111. In this case, an interaction force may be caused between the mounting portion110and each of the first elastic sheet212and the second elastic sheet213, thereby preventing the lighting assembly200from being disengaged from the mounting portion110. Such a clamped connection structure is relatively simple, and the assembling manipulation of the lighting assembly200and the mounting portion110can be simplified.

As illustrated inFIG. 7, in an alternative example, each of the first elastic sheet212and the second elastic sheet213includes a connecting portion214and a snap-fit portion215. The snap-fit portion215is connected to the base body211by means of the connecting portion214and is clamped with the snap-fit protrusion111. The snap-fit portion215of the first elastic sheet212and the snap-fit portion215of the second elastic sheet213are bent towards each other. That is, the snap-fit portion215of the first elastic sheet212is bent towards the direction close to the second elastic sheet213, and the snap-fit portion215of the second elastic sheet213is bent towards the direction close to the first elastic sheet212. With the bent structure as described herein, the snap-fit portion215of the first elastic sheet212and the snap-fit portion215of the second elastic sheet213both have a protruding structure, and the protruding structure can be in better snap fit with the snap-fit protrusions111, thus improving the reliability of the clamped connection.

In a specific example, for a single lighting assembly200, only one of the first elastic sheet212and the second elastic sheet213is provided. However, considering that such a structure design may easily lead to inadequate strength of connection between the lighting assembly200and the mounting portion110, a plurality of first elastic sheets212or a plurality of second elastic sheets213may be arranged in the extending direction of the mounting portion110in a single lighting assembly200, or a plurality of first elastic sheets212and a plurality of second elastic sheets213may be arranged in the extending direction of the mounting portion110in a single lighting assembly200. With increasing number of the first elastic sheets212and the second elastic sheets213, the connection points between the lighting assembly200and the mounting portion110may increase, thereby providing enhanced connection strength between the lighting assembly200and the mounting portion110.

As illustrated inFIG. 4, the connecting portion214may specifically include a first connecting plate214aand a second connecting plate214b. The first connecting plate214aand the second connecting plate214bare connected into an L-shaped structure. The first connecting plate214afits and is in fixed connection with the base body211, the first connecting plate214aand the base body211may specifically be fixedly connected by a third fastening component260, and the third fastening component260may be a screw. The second connecting plate214bis connected to the snap-fit portion215. Due to a large contact area between the first connecting plate214aand the base body211, fixed connection of the first connecting plate214aand the base body211may result in high connection strength, which may allow the lighting assembly200to have higher structural strength.

As illustrated inFIG. 4andFIG. 7, in this example of the present disclosure, the lighting assembly200may further include a surface cover240. The optical device230specifically includes a reflector231and a diffusion casing232housing the reflector231. The reflector231is disposed on a light-emitting side of the light-emitting device220, and thus light emitted by the light-emitting device220is reflected by the reflector231, so that the light can be concentrated to shine out, thereby improving the utilization of the light. The diffusion casing232is in fixed connection with the base210and has a top232aarranged opposite to the light-emitting device220. That is, the diffusion casing232has a semi-enclosed structure and may be fixed to the base210to form an enclosed cavity. At least a part of the light-emitting device220and the reflector231are located in the enclosed cavity. The light emitted by the light-emitting device220may shine on the diffusion casing232after being reflected by the reflector231. The diffusion casing232may further adjust the direction of the light, which may allow the light to shine out more uniformly through the diffusion casing232. The surface cover240is fastened around the diffusion casing232and mainly serves as an exterior component of the lighting assembly200, so as to protect the components such as the diffusion casing232, the reflector231, and the light-emitting device220and meet the user demand on the appearance of the lamp.

In a further example, the optical device230may further include a light transmitting glass233. The surface cover240has an opening241at the top. The light transmitting glass233is disposed at the opening241and covers the top232aof the diffusion casing232. In this case, the surface cover240and the light transmitting glass233may both serve as exterior components of the lighting assembly200. The surface cover240mainly serves to protect the components, the light transmitting glass233may provide more aesthetically pleasing appearance, and therefore, such a structure may meet the requirements for both of the structural strength and appearance of the lamp.

It should be noted that, the light transmitting glass233may be optical glass or treated glass, such as sand-blasted glass and silk-screen glass. In particular, the structural form of the light transmitting glass233may be flexibly chosen in accordance with different user requirements, and the examples of the present disclosure are not limited in this aspect.

In actual use, a lamp may be used in an environment with high humidity or an environment with the possibility of exposure to water, and therefore, the water-proof performance of the lamp becomes one of key factors determining the service life of the lamp. For example, the lamp is used outdoors, and in this case, the lamp is specifically an outdoor lamp. On this basis, the optical device230may further include a diffusion casing sealing component234, and the diffusion casing sealing component234is hermetically disposed between the top232aof the diffusion casing232and the light transmitting glass233. The diffusion casing sealing component234may be a sealing ring having a circular cross section, a semicircular cross section, or a cross section in any other suitable shape, which can prevent the liquid such as water from entering the lighting assembly200through the gap between the diffusion casing232and the light transmitting glass233, thus achieving the purpose of improving the water-proof performance of the lamp.

For the convenience of mounting of the diffusion casing sealing component234, a first sealing component accommodation groove232aamay be provided at the top232aof the diffusion casing232. The diffusion casing sealing component234is located in the first sealing component accommodation groove232aa. The first sealing component accommodation groove232aamay be an annular groove, which may be provided at the edge of the top232ato obtain a large space size, thereby facilitating being provided with a larger diffusion casing sealing component234and better sealing effect between the diffusion casing232and the light transmitting glass233. When the lamp is assembled, the diffusion casing sealing component234is placed in the first sealing component accommodation groove232aa, and then the diffusion casing232and the light transmitting glass233are installed together, so that the diffusion casing sealing component234is pressed to be in good fit with the diffusion casing232and the light transmitting glass233.

Referring toFIG. 7, for the convenience of mounting, a first snap-fit protrusion216protruding towards the diffusion casing232may be provided on the base210, a second snap-fit protrusion232bmay be provided on an inner surface of the diffusion casing232, and the first snap-fit protrusion216is in snap fit with the second snap-fit protrusion232b. Specifically, the first snap-fit protrusion216may be provided with a groove or a through hole. The second snap-fit protrusion232bis in snap fit with the groove or the through hole. There may be a plurality of first snap-fit protrusions216that are arranged along the edge of the base210. Correspondingly, there may be a plurality of second snap-fit protrusions232bthat are arranged in the circumferential direction of the diffusion casing232. The plurality of first snap-fit protrusions216are clamped with the second snap-fit protrusions232bin one-to-one correspondence, thereby improving the installation reliability between the base210and the diffusion casing232.

Similarly, a third snap-fit protrusion is provided on one of an outer surface of the diffusion casing232and an inner surface of the surface cover240, while a snap-fit depression is provided on the other of the outer surface of the diffusion casing232and the inner surface of the surface cover240, and the third snap-fit protrusion is in snap fit with the snap-fit depression. There may be a plurality of snap-fit protrusions and a plurality of snap-fit depressions, so as to improve the snap-fit effect. As illustrated inFIG. 4andFIG. 7, in a specific example, the snap-fit depression232cmay be provided on the outer surface of the diffusion casing232, while the third snap-fit protrusion242may be provided on the inner surface of the surface cover240. Each of the outer surface of the diffusion casing232and the inner surface of the surface cover240may include a plurality of lateral surfaces sequentially connected to each other. One or more snap-fit depressions232cmay be provided on each lateral surface of the diffusion casing232, and one or more third snap-fit protrusions242may be provided on each lateral surface of the surface cover240. To guarantee the reliability of the clamped connection and control the manufacturing cost of the lamp, a plurality of snap-fit depressions232cmay be provided on a part of the lateral surfaces of the diffusion casing232.

For the convenience of assembling the base210and the diffusion casing232, an annular locating groove217may be provided on the base210. The bottom edge of the diffusion casing232is located in the annular locating groove217, a locating flange232dis provided on the outer surface of the diffusion casing232, and the locating flange232dis in locating fit with the top edge of the base210. In specific manipulation, since the annular locating groove217is easily visible, the bottom edge of the diffusion casing232can be aligned to the annular locating groove217and located in the annular locating groove217, and then the diffusion casing232is continuously moved, so that the locating flange232dof the diffusion casing232is in location fit with the top edge of the base210, thereby realizing pre-locating of the base210and the diffusion casing232. Then, the base210and the diffusion casing232are in precise snap fit. Certainly, such a structure may also assist in limiting the relative positions of the base210and the diffusion casing232, thus sharing the acting forces on the respective snap-fit structures and prolonging the service life of the snap-fit structures.

In this example of the present disclosure, a plurality of radiating fins218spaced apart from each other may be disposed on the outer surface of the base210. These radiating fins218may assist in dissipating the heat generated during the operation of the lamp. Certainly, these radiating fins218may also further optimize the appearance of the lamp.

It should be noted that when the base210includes the base body211, the first snap-fit protrusion216, the annular locating groove217and the radiating fin218may be all provided on the base body211.

The lighting assembly200provided by this example of the present disclosure may have an overall irregular or regular structure. In case of the regular structure, the lamp can be manufactured more conveniently. For example, the lighting assembly200may have a triangular structure, a square structure, a diamond-shaped structure, a circular structure, an oval-shaped structure, or the like, that is, when viewed from the top or the bottom, the lamp is triangular, square, diamond-shaped, circular, oval-shaped, etc. Relatively speaking, when the lighting assembly200is provided in a triangular structure, a square structure, or a diamond-shaped structure, the gap between the adjacent lighting assemblies200can be reduced as much as possible by optimizing the arrangement of the plurality of lighting assemblies200, thus improving the space utilization of the entire lamp.

The light-emitting device220is one of core devices for realizing the light-emitting function in the lamp. As illustrated inFIG. 4andFIG. 7, in this example of the present disclosure, in addition to the second electrical terminal223, the light-emitting device220may further include a light source plate221and a plurality of light-emitting units222disposed on the light source plate221. The second electrical terminal223is mounted on the light source plate221and electrically connected to the plurality of light-emitting units222. The energy that the light-emitting device220needs may be provided from the first electrical terminal150to reach each light-emitting unit222sequentially through the second electrical terminal223and the light source plate221, so as to enable each light-emitting unit222to emit light. Such a light-emitting device220has the advantage of compact structure, and when the lighting assembly200is mounted on the mounting base100, the second electrical terminal223and the first electrical terminal150are plugged into each other, so as to realize assembling and electrical connection between the second electrical terminal223and the first electrical terminal150, thereby providing convenient manipulation and high assembling efficiency.

As illustrated inFIG. 11andFIG. 12, when the mounting portion110is provided in a strip-shaped structure, the mounting portion110may have a plurality of mounting holes112sequentially arranged in the extending direction of the mounting portion110. The first electrical terminal150is mounted in the mounting hole112. When the first electrical terminal150is mounted, the first electrical terminal150passes through the mounting hole112with one part trapped within the mounting portion110and the other part sticking out relative to the mounting portion110to be in plug-in fit with the second electrical terminal223. With such a solution, the structure of the mounting portion110is simplified, so that the first electrical terminal150can be mounted on the mounting portion110more simply and rapidly.

In an alternative example, for the convenience of allowing the first electrical terminal150to be mounted on the mounting portion110, the first electrical terminal150may include a main body151and a clamping portion152provided on the main body151. The main body151is in plug-in fit with the second electrical terminal223, and the clamping portion152is clamped at the mounting hole112. The main body151is approximately column-shaped. The clamping portion152may be structured as a clamped claw, which may undergo deformation when being acted upon by a force. When the first electrical terminal150is mounted, an acting force may be applied to the main body151, causing the clamping portion152to stick into the mounting hole112. In this case, the clamping portion152is deformed after being restricted by the wall of the mounting hole112. When the clamping portion152passes through the mounting hole112, the restriction of the wall of the mounting hole112on the clamping portion152is lifted, allowing the clamping portion152to recover deformation and thus come into contact with one side, far away from the base210, of the mounting portion110. Thus, the first electrical terminal150cannot be disengaged from the mounting hole112.

To further improve the waterproofness of the lamp, the lighting assembly200or the mounting base100may further include a terminal sealing component. The terminal sealing component may be a sealing ring having an O-shaped cross section, a square cross section, or a cross section in any other suitable shape. When the second electrical terminal223is positioned around the first electrical terminal150, the terminal sealing component, as a part of the light-emitting device220, is hermetically disposed between the second electrical terminal223and the base210(in particular, the base body211). When the first electrical terminal150is positioned around the second electrical terminal223, the terminal sealing component161, as a part of the mounting base100, is hermetically disposed between the first electrical terminal150and the base210(in particular, the base body211).

Alternatively, a second sealing component accommodation groove is provided at the periphery of the second electrical terminal223or the periphery of the first electrical terminal150, and the terminal sealing component is located in the second sealing component accommodation groove, thereby facilitating mounting of the terminal sealing component. In this example of the present disclosure, the first electrical terminal150is positioned around the second electrical terminal223, and the second sealing component accommodation groove153is provided at the periphery of the first electrical terminal150. The terminal sealing component161is located in the second sealing component accommodation groove153to be hermetically provided between the first electrical terminal150and the base210.

In a further example, as illustrated inFIG. 7, in addition to the base body211as described above, the base210may further include an annular protrusion219. The annular protrusion219sticks out relative to the base body211, and the base body211surrounds the annular protrusion219. A terminal accommodation hole219ais provided in the annular protrusion219, and the second electrical terminal223and the first electrical terminal150are both located in the terminal accommodation hole219a. The terminal sealing component as described above is hermetically disposed between the second electrical terminal223and the wall of the terminal accommodation hole219aor between the first electrical terminal150and the wall of the terminal accommodation hole219a. Since the annular protrusion219sticks out relative to the base body211, the terminal accommodation hole219ahas a large size in the axial direction thereof with increased area of the wall thereof, so that a larger sealing area can be formed between the terminal sealing component and the wall of the terminal accommodation hole219a, thereby optimizing the water-proof performance of the lamp.

As illustrated inFIG. 11, in this example of the present disclosure, to further improve the water-proof performance of the lamp, the mounting base100may further include a mounting portion sealing component162, and the mounting portion sealing component162is hermetically disposed between the mounting portion110and the first electrical terminal150. The mounting portion sealing component162may be a sealing ring having an O-shaped cross section, a square cross section, or the like.

In addition to the main body151as described above, the first electrical terminal150may further include the annular flange154provided on the main body151. The mounting portion sealing component162is hermetically disposed between the annular flange154and the mounting portion110. In this case, the annular flange154is disposed opposite to the surface, facing the base210, of the mounting portion110. After the lighting assembly200is mounted on the mounting base100, the mounting portion sealing component162is clamped by the annular flange154and the mounting portion110, and the annular flange154and the mounting portion110apply a high positive pressure on the mounting portion sealing component162, resulting in higher sealing performance between the first electrical terminal150and the mounting portion110.

In addition to the mounting portion110as described above, the mounting base100may further include a top cover120, and the top cover120is disposed at an end of the mounting portion110. The mounting portion110may have a hollow structure, thus achieving lightweight lamp design. The top cover120may seal at least a part of the end of the mounting portion110, so that the inner space of the mounting portion110is exposed as little as possible, thus guaranteeing the appearance quality of the lamp.

As illustrated inFIG. 8toFIG. 17, in an alternative example, the top cover120may include a top plate121and a bottom plate122. The top plate121and the bottom plate122are connected to form an L-shaped structure. The top plate121is fixed to the mounting portion110. Specifically, the top plate121may be fixedly connected to the mounting portion110by means of a first fastening component171. The mounting portion110has a limiting groove113. The bottom plate122may extend into the limiting groove113and be in limiting fit with the limiting groove113, so that the movement of top cover120in the axial direction of the mounting hole112of the mounting portion110is restricted. With such a structure, the top cover120may be inserted in the mounting portion110from the top end of the mounting portion110, and thus the mounting manipulation of the top cover120is simplified.

The sidewall of the mounting portion110is designed with a thickness, so that the top cover120can be fixed to the sidewall of the mounting portion110. However, this method may lead to a large sidewall thickness of the mounting portion110, which may be adverse to lightweight lamp design. In view of this, the mounting portion110may be provided with a top cover mounting portion114inside. The top cover mounting portion114is provided with a fastening hole114a, and the first fastening component171for fixing the top plate121is in fastening fit with the fastening hole114a. The fastening hole114amay be a threaded hole, and the first fastening component171is screwed in the fastening hole114a, so that the first fastening component171and the fastening hole114aare in screw-thread fit with each other. The fastening hole114amay also be an unthreaded hole, and thread is tapped during the process of screwing the first fastening component171in the fastening hole114a, thus realizing screw-thread fit between the first fastening component171and the fastening hole114a. In addition, the fastening hole114amay have a notch, so as to facilitate machining of the fastening hole114a. Further, top cover mounting portions114may be disposed on two opposite sides of the mounting portion110, so as to allow the top cover120to be more securely fixed.

In this example of the present disclosure, in order to drive the lamp to emit light, the connecting wire for electrical connection is required. The connecting wire for electrical connection may specifically include an inlet wire181and an outlet wire182. To limit the position of the connecting wire for electrical connection, the bottom plate122may be provided with a notch122a, and the notch122aallows the connecting wire for electrical connection to pass through. Specifically, there may be two top covers120that are mounted at two ends of the mounting portion110, respectively. Thus, the inlet wire181may go through the notch122aof one top cover120, while the outlet wire182may go through the notch122aof the other top cover120. Under the restriction of the notch122a, the inlet wire181and the outlet wire182are not prone to changing in position when being acted upon by a pulling force, thus preventing the inlet wire181and the outlet wire182from being pulled.

The bottom plate122of the top cover120may have a flat-plate structure with one end connected to the top plate121and the other end serving as a free end. In another example, the top cover120further includes a bending plate123. The bending plate123and the top plate121are connected to two opposite sides of the bottom plate122, respectively. The bending plate123is bent towards the direction away from the light-emitting device220and is in sliding fit with the inner wall of the mounting portion110. When the top cover120is inserted in the mounting portion110, the bending plate123is slid relative to the mounting portion110, thus guiding the movement of the top cover120and facilitating the mounting of the top cover120.

As illustrated inFIG. 11andFIG. 12, it should be noted that the mounting base100further includes a circuit board190. The connecting wire for electrical connection as described above is electrically connected to the circuit board190. The circuit board190is electrically connected to the light-emitting device220(in particular, electrically connected to the second electrical terminal223through the first electrical terminal150). The mounting base100further includes a bottom cover130, and the bottom cover130is fixed to the mounting portion110to form an accommodation cavity. The circuit board190is embedded in the accommodation cavity. Since the circuit board190is encapsulated in the mounting portion110through embedment, on the one hand, the circuit board190can be enveloped reliably and protected against impurities such as liquid, thus allowing the circuit board190to operate reliably, and on the other hand, the mounting of the circuit board190can be simplified.

In a further example, the bottom cover130may include a cover body131and a matching protrusion132provided on the cover body131. The cover body131may have a flat-plate structure. The matching protrusion132may be structured in the form of a plurality of discrete blocks, and extend in a direction consistent with the extending direction of the mounting portion110. A matching groove is formed between the edge of the cover body131and the matching protrusion132. The mounting portion110is provided with a matching protrusion115inside, and the matching protrusion115is in snap fit with the matching groove. The connection between the bottom cover130and the mounting portion110can be achieved by means of snap-fit connection between the matching protrusion115and the matching groove, so that the manipulation is simple, and the connected structure has high reliability.

To simplify the manufacturing procedure of the bottom cover130, the matching protrusion132may be provided in a strip-shaped structure and extend in a direction parallel to the extending direction of the mounting portion110. As such, the matching protrusion132may have an integrated structure and thus can be manufactured more conveniently, and the integrated matching protrusion132better ensure that a plurality of positions of the matching protrusion132are at the same height, thus allowing the bottom cover130to be in exact fit with the matching protrusion132in different positions, so as to improve the fixed strength of the bottom cover130and the matching protrusion132.

During embedment, it is required to fill the mounting portion110with glue. For the convenience of controlling the amount of glue filled by the operator, the mounting portion110may be provided with a glue identification portion116inside. The glue identification portion116may specifically have a strip-shaped protruding structure. When the glue filled reaches the glue identification portion116, it indicates that the amount of the glue filled basically meet the requirement. In this case, the operator may determine whether glue filling is continued according to the actual situation.

To satisfy higher demand on lighting, there may be a plurality of mounting portions110that are arranged side by side, so that a plurality of rows of lighting assemblies200can be provided. This involves connection between different mounting portions110. For this, as illustrated inFIG. 1toFIG. 3, in the lamp provided by the example of the present disclosure, the mounting base100further includes a mounting bracket140, and the mounting bracket140connects at least two mounting portions110. As such, the mounting portions110connected to the same mounting bracket140can be retained at the identical height, thereby further improving the appearance and the luminous effect of the lamp.

To guarantee the appearance and the luminous effect of the lamp more reliably, the mounting portions110may be arranged at an equal distance from each other.

In a specific example, the mounting portions110may be connected by the mounting brackets140in pairs to form a plurality of sets of mounting portions110. In this case, since each set of mounting portions110has no connection relationship with another set, a difference in height may be caused, which would be adverse to guarantee the appearance and the luminous effect of the lamp. In view of this problem, as illustrated inFIG. 21, every two adjacent mounting portions110may be connected by the mounting bracket140. That is, all the mounting portions110are connected by the mounting brackets140, so that the mounting portions110can be all retained at the identical height and can be at uniform intervals, thereby solving the foregoing problem.

As illustrated inFIG. 18toFIG. 20, the mounting bracket140may include a main body plate141, and a plurality of mounting plates142which are sequentially mounted on the same side of the main body plate141. A mounting groove143is formed between a part of the adjacent mounting plates142, while a separation groove144is formed between a part of the adjacent mounting plates142, and the mounting groove143and the separation groove144are arranged alternately. The mounting portion110is connected in the mounting groove143. Adjacent mounting grooves143are spaced apart by the separation groove144. This method may leave space for related mounting manipulation, and may further leave space for arrangement of the lighting assemblies200.

At least a part of the plurality of mounting plates142are in snap fit with the mounting portion110, so that the mounting portion110and the mounting bracket140are assembled together. In addition, at least a part of the mounting plates142may be fixed to the mounting portion110through second fastening components172, thereby facilitating assembling and guaranteeing the assembly reliability. Specifically, a part of the mounting plates142may be in snap fit with the mounting portion110, while the rest may be fixed to the mounting portion110through the second fastening components172. Alternatively, a part of the mounting plates142may be in snap fit with the mounting portion110and also fixed to the mounting portion110through the second fastening components172. To improve the mounting strength and facilitating manipulation, in this example of the present disclosure, the mounting plates142clamped with the same side of each mounting portion110are preferably fixed to the mounting portion110by means of the second fastening components172, while the other mounting plates142are clamped with the mounting portion110.

Based on the above examples, one of mounting plates located on the same side of the adjacent mounting grooves143is provided with a first bracket mounting hole142a, while the other of the mounting plates located on the same side of the adjacent mounting grooves143is provided with a second bracket mounting hole142b, and a distance between the first bracket mounting hole142aand the main body plate141is greater than a distance between the second bracket mounting hole142band the main body plate141. That is, there is a difference in height between the first bracket mounting hole142aand the second bracket mounting hole142b, thus preventing interference when the mounting portion110is mounted by the operator.

It should be noted that the above-mentioned “mounting plates located on the same side of the adjacent mounting grooves143” refer to, among all the mounting plates142that form the adjacent mounting grooves143, the mounting plates located on the same side of the mounting groove143. Taking four mounting plates142as illustrated inFIG. 19as an example, the four mounting plates142are sequentially to be the first mounting plate, the second mounting plate, the third mounting plate, and the fourth mounting plate, the mounting grooves143are formed between the first mounting plate and the second mounting plate and between the third mounting plate and the fourth mounting plate, and the separation groove144is formed between the second mounting plate and the third mounting plate. In this case, the second mounting plate and the fourth mounting plate are regarded as the “mounting plates located on the same side of the adjacent mounting grooves143” as described above.

For facilitating wiring, a wire passing hole141ais provided at a position, corresponding to a bottom of the separation groove144, on the main body plate141. That is, the wire passing hole141ais communicated with the separation groove144.

The above examples of the present disclosure focus on the differences between the various examples. As long as the different optimized features between the various examples are not contradictory, they can be combined to form better examples. Considering the simplicity of the text, no more repeated descriptions are provided here.

The above contents are only the examples of the present disclosure, but not intended to limit the present disclosure. Those skilled in the art can make various changes and modifications to the present disclosure. Any modifications, equivalent replacements, improvements and the like that are made without departing from the spirit and the principle of the present disclosure shall all fall within the scope of claims of the present disclosure.
