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 in
As illustrated in
In the lamp provided by the examples of the present disclosure, the plurality of lighting assemblies 200 are provided, and the mounting base 100 may be in detachable connection with the plurality of lighting assemblies 200. Thus, the effect of enhancing the luminous intensity of the lamp can be achieved by increasing the number of the lighting assemblies 200, thereby satisfying the user demand on lighting, especially the user demand on lighting in a large space. Moreover, the mounting base 100 is in detachable connection with each lighting assembly 200 and supplies power to the lighting assembly 200 by means of plug-in connection between the first electrical terminal 150 and the second electrical terminal 223. As such, different lighting assemblies 200 can 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 terminal 150 and the second electrical terminal 223 may contribute to positioning to a certain extent, so that the mounting base 100 and the lighting assembly 200 of the lamp can be installed more rapidly.
In this example of the present disclosure, the mounting portion 110 may be provided in a strip-shaped structure. The plurality of first electrical terminals 150 are sequentially mounted in the extending direction of the mounting portion 110, so as to allow the plurality of lighting assemblies 200 to be mounted. With the strip-shaped structure, the extending direction of the mounting portion 110 is identical to the length direction of the mounting portion 110. The mounting portion 110 may have a plurality of positions for mounting the lighting assemblies 200, and these positions may be distributed uniformly, so that the plurality of lighting assemblies 200 can be uniformly mounted on the mounting portion 110. As such, the plurality of lighting assemblies 200 mounted on the same mounting portion 110 may 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 portion 110 may be chosen flexibly in accordance with actual user demand, so as to allow different number of lighting assemblies 200 to be mounted, and therefore, the lamp has better scalability.
The mounting portion 110 and the lighting assembly 200 may be installed together by means of bolted-on connection, riveting, clamped connection, etc. To guarantee the installation reliability of the lighting assembly 200 on the mounting portion 110 and further to facilitate the mounting manipulation, clamped connection is preferred between the lighting assembly 200 and the mounting portion 110 in this example of the present disclosure.
Further, the structure for realizing the clamped connection between the lighting assembly 200 and the mounting portion 110 may be in numerous forms. For example, a snap-fit column may be provided on the lighting assembly 200, while a snap-fit hole is provided in the mounting portion 110, and the clamped connection between the lighting assembly 200 and the mounting portion 110 can 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 in
Alternatively, a plurality of snap-fit protrusions 111 may be provided on the side surface of the mounting portion 110, the snap-fit protrusions 111 are arranged in the extending direction of the mounting portion 110, and each lighting assembly 200 is in snap fit with the corresponding snap-fit protrusion 111. Certainly, the snap-fit protrusion 111 may be provided in a strip-shaped structure as well. That is, the snap-fit protrusion 111 extends in the extending direction of the mounting portion 110, and the plurality of lighting assemblies 200 mounted on the same mounting portion 110 are all in snap fit with the same snap-fit protrusion 111. Since the snap-fit protrusions 111 of a single mounting portion 110 are at the same height throughout, the plurality of lighting assemblies 200 mounted on the mounting portion 110 can be retained at the identical height more reliably, thereby improving the appearance and the luminous effect of the lamp.
The base 210 of the lighting assembly 200 may include a base body 211, and a first elastic sheet 212 and a second elastic sheet 213 that are mounted on the base body 211. The light-emitting device 220 and the optical device 230 are both mounted on the base body 211. The first elastic sheet 212 and the second elastic sheet 213 are arranged opposite and clamped on the snap-fit protrusions 111 on two opposite outer sides of the mounting portion 110, respectively. The first elastic sheet 212 and the second elastic sheet 213 both 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 portion 110 may be caused.
Specifically, when the lighting assembly 200 is assembled, the first elastic sheet 212 and the second elastic sheet 213 are first brought into contact with the mounting portion 110, and then an external force is applied on the lighting assembly 200, which causes the first elastic sheet 212 and the second elastic sheet 213 to deform under the force and thus slide relative to the mounting portion 110 until the first elastic sheet 212 and the second elastic sheet 213 are clamped with the snap-fit protrusions 111. In this case, an interaction force may be caused between the mounting portion 110 and each of the first elastic sheet 212 and the second elastic sheet 213, thereby preventing the lighting assembly 200 from being disengaged from the mounting portion 110. Such a clamped connection structure is relatively simple, and the assembling manipulation of the lighting assembly 200 and the mounting portion 110 can be simplified.
As illustrated in
In a specific example, for a single lighting assembly 200, only one of the first elastic sheet 212 and the second elastic sheet 213 is provided. However, considering that such a structure design may easily lead to inadequate strength of connection between the lighting assembly 200 and the mounting portion 110, a plurality of first elastic sheets 212 or a plurality of second elastic sheets 213 may be arranged in the extending direction of the mounting portion 110 in a single lighting assembly 200, or a plurality of first elastic sheets 212 and a plurality of second elastic sheets 213 may be arranged in the extending direction of the mounting portion 110 in a single lighting assembly 200. With increasing number of the first elastic sheets 212 and the second elastic sheets 213, the connection points between the lighting assembly 200 and the mounting portion 110 may increase, thereby providing enhanced connection strength between the lighting assembly 200 and the mounting portion 110.

As illustrated in
In a further example, the optical device 230 may further include a light transmitting glass 233. The surface cover 240 has an opening 241 at the top. The light transmitting glass 233 is disposed at the opening 241 and covers the top 232a of the diffusion casing 232. In this case, the surface cover 240 and the light transmitting glass 233 may both serve as exterior components of the lighting assembly 200. The surface cover 240 mainly serves to protect the components, the light transmitting glass 233 may 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 glass 233 may be optical glass or treated glass, such as sand-blasted glass and silk-screen glass. In particular, the structural form of the light transmitting glass 233 may 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 device 230 may further include a diffusion casing sealing component 234, and the diffusion casing sealing component 234 is hermetically disposed between the top 232a of the diffusion casing 232 and the light transmitting glass 233. The diffusion casing sealing component 234 may 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 assembly 200 through the gap between the diffusion casing 232 and the light transmitting glass 233, thus achieving the purpose of improving the water-proof performance of the lamp.
For the convenience of mounting of the diffusion casing sealing component 234, a first sealing component accommodation groove 232aa may be provided at the top 232a of the diffusion casing 232. The diffusion casing sealing component 234 is located in the first sealing component accommodation groove 232aa. The first sealing component accommodation groove 232aa may be an annular groove, which may be provided at the edge of the top 232a to obtain a large space size, thereby facilitating being provided with a larger diffusion casing sealing component 234 and better sealing effect between the diffusion casing 232 and the light transmitting glass 233. When the lamp is assembled, the diffusion casing sealing component 234 is placed in the first sealing component accommodation groove 232aa, and then the diffusion casing 232 and the light transmitting glass 233 are installed together, so that the diffusion casing sealing component 234 is pressed to be in good fit with the diffusion casing 232 and the light transmitting glass 233.
Referring to
Similarly, a third snap-fit protrusion is provided on one of an outer surface of the diffusion casing 232 and an inner surface of the surface cover 240, while a snap-fit depression is provided on the other of the outer surface of the diffusion casing 232 and the inner surface of the surface cover 240, 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 in
For the convenience of assembling the base 210 and the diffusion casing 232, an annular locating groove 217 may be provided on the base 210. The bottom edge of the diffusion casing 232 is located in the annular locating groove 217, a locating flange 232d is provided on the outer surface of the diffusion casing 232, and the locating flange 232d is in locating fit with the top edge of the base 210. In specific manipulation, since the annular locating groove 217 is easily visible, the bottom edge of the diffusion casing 232 can be aligned to the annular locating groove 217 and located in the annular locating groove 217, and then the diffusion casing 232 is continuously moved, so that the locating flange 232d of the diffusion casing 232 is in location fit with the top edge of the base 210, thereby realizing pre-locating of the base 210 and the diffusion casing 232. Then, the base 210 and the diffusion casing 232 are in precise snap fit. Certainly, such a structure may also assist in limiting the relative positions of the base 210 and the diffusion casing 232, 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 fins 218 spaced apart from each other may be disposed on the outer surface of the base 210. These radiating fins 218 may assist in dissipating the heat generated during the operation of the lamp. Certainly, these radiating fins 218 may also further optimize the appearance of the lamp.
It should be noted that when the base 210 includes the base body 211, the first snap-fit protrusion 216, the annular locating groove 217 and the radiating fin 218 may be all provided on the base body 211.
The lighting assembly 200 provided 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 assembly 200 may 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 assembly 200 is provided in a triangular structure, a square structure, or a diamond-shaped structure, the gap between the adjacent lighting assemblies 200 can be reduced as much as possible by optimizing the arrangement of the plurality of lighting assemblies 200, thus improving the space utilization of the entire lamp.
The light-emitting device 220 is one of core devices for realizing the light-emitting function in the lamp. As illustrated in
As illustrated in
In an alternative example, for the convenience of allowing the first electrical terminal 150 to be mounted on the mounting portion 110, the first electrical terminal 150 may include a main body 151 and a clamping portion 152 provided on the main body 151. The main body 151 is in plug-in fit with the second electrical terminal 223, and the clamping portion 152 is clamped at the mounting hole 112. The main body 151 is approximately column-shaped. The clamping portion 152 may be structured as a clamped claw, which may undergo deformation when being acted upon by a force. When the first electrical terminal 150 is mounted, an acting force may be applied to the main body 151, causing the clamping portion 152 to stick into the mounting hole 112. In this case, the clamping portion 152 is deformed after being restricted by the wall of the mounting hole 112. When the clamping portion 152 passes through the mounting hole 112, the restriction of the wall of the mounting hole 112 on the clamping portion 152 is lifted, allowing the clamping portion 152 to recover deformation and thus come into contact with one side, far away from the base 210, of the mounting portion 110. Thus, the first electrical terminal 150 cannot be disengaged from the mounting hole 112.
To further improve the waterproofness of the lamp, the lighting assembly 200 or the mounting base 100 may 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 terminal 223 is positioned around the first electrical terminal 150, the terminal sealing component, as a part of the light-emitting device 220, is hermetically disposed between the second electrical terminal 223 and the base 210 (in particular, the base body 211). When the first electrical terminal 150 is positioned around the second electrical terminal 223, the terminal sealing component 161, as a part of the mounting base 100, is hermetically disposed between the first electrical terminal 150 and the base 210 (in particular, the base body 211).
Alternatively, a second sealing component accommodation groove is provided at the periphery of the second electrical terminal 223 or the periphery of the first electrical terminal 150, 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 terminal 150 is positioned around the second electrical terminal 223, and the second sealing component accommodation groove 153 is provided at the periphery of the first electrical terminal 150. The terminal sealing component 161 is located in the second sealing component accommodation groove 153 to be hermetically provided between the first electrical terminal 150 and the base 210.
In a further example, as illustrated in
As illustrated in
In addition to the main body 151 as described above, the first electrical terminal 150 may further include the annular flange 154 provided on the main body 151. The mounting portion sealing component 162 is hermetically disposed between the annular flange 154 and the mounting portion 110. In this case, the annular flange 154 is disposed opposite to the surface, facing the base 210, of the mounting portion 110. After the lighting assembly 200 is mounted on the mounting base 100, the mounting portion sealing component 162 is clamped by the annular flange 154 and the mounting portion 110, and the annular flange 154 and the mounting portion 110 apply a high positive pressure on the mounting portion sealing component 162, resulting in higher sealing performance between the first electrical terminal 150 and the mounting portion 110.
In addition to the mounting portion 110 as described above, the mounting base 100 may further include a top cover 120, and the top cover 120 is disposed at an end of the mounting portion 110. The mounting portion 110 may have a hollow structure, thus achieving lightweight lamp design. The top cover 120 may seal at least a part of the end of the mounting portion 110, so that the inner space of the mounting portion 110 is exposed as little as possible, thus guaranteeing the appearance quality of the lamp.
As illustrated in
The sidewall of the mounting portion 110 is designed with a thickness, so that the top cover 120 can be fixed to the sidewall of the mounting portion 110. However, this method may lead to a large sidewall thickness of the mounting portion 110, which may be adverse to lightweight lamp design. In view of this, the mounting portion 110 may be provided with a top cover mounting portion 114 inside. The top cover mounting portion 114 is provided with a fastening hole 114a, and the first fastening component 171 for fixing the top plate 121 is in fastening fit with the fastening hole 114a. The fastening hole 114a may be a threaded hole, and the first fastening component 171 is screwed in the fastening hole 114a, so that the first fastening component 171 and the fastening hole 114a are in screw-thread fit with each other. The fastening hole 114a may also be an unthreaded hole, and thread is tapped during the process of screwing the first fastening component 171 in the fastening hole 114a, thus realizing screw-thread fit between the first fastening component 171 and the fastening hole 114a. In addition, the fastening hole 114a may have a notch, so as to facilitate machining of the fastening hole 114a. Further, top cover mounting portions 114 may be disposed on two opposite sides of the mounting portion 110, so as to allow the top cover 120 to 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 wire 181 and an outlet wire 182. To limit the position of the connecting wire for electrical connection, the bottom plate 122 may be provided with a notch 122a, and the notch 122a allows the connecting wire for electrical connection to pass through. Specifically, there may be two top covers 120 that are mounted at two ends of the mounting portion 110, respectively. Thus, the inlet wire 181 may go through the notch 122a of one top cover 120, while the outlet wire 182 may go through the notch 122a of the other top cover 120. Under the restriction of the notch 122a, the inlet wire 181 and the outlet wire 182 are not prone to changing in position when being acted upon by a pulling force, thus preventing the inlet wire 181 and the outlet wire 182 from being pulled.
The bottom plate 122 of the top cover 120 may have a flat-plate structure with one end connected to the top plate 121 and the other end serving as a free end. In another example, the top cover 120 further includes a bending plate 123. The bending plate 123 and the top plate 121 are connected to two opposite sides of the bottom plate 122, respectively. The bending plate 123 is bent towards the direction away from the light-emitting device 220 and is in sliding fit with the inner wall of the mounting portion 110. When the top cover 120 is inserted in the mounting portion 110, the bending plate 123 is slid relative to the mounting portion 110, thus guiding the movement of the top cover 120 and facilitating the mounting of the top cover 120.
As illustrated in
In a further example, the bottom cover 130 may include a cover body 131 and a matching protrusion 132 provided on the cover body 131. The cover body 131 may have a flat-plate structure. The matching protrusion 132 may be structured in the form of a plurality of discrete blocks, and extend in a direction consistent with the extending direction of the mounting portion 110. A matching groove is formed between the edge of the cover body 131 and the matching protrusion 132. The mounting portion 110 is provided with a matching protrusion 115 inside, and the matching protrusion 115 is in snap fit with the matching groove. The connection between the bottom cover 130 and the mounting portion 110 can be achieved by means of snap-fit connection between the matching protrusion 115 and the matching groove, so that the manipulation is simple, and the connected structure has high reliability.
To simplify the manufacturing procedure of the bottom cover 130, the matching protrusion 132 may be provided in a strip-shaped structure and extend in a direction parallel to the extending direction of the mounting portion 110. As such, the matching protrusion 132 may have an integrated structure and thus can be manufactured more conveniently, and the integrated matching protrusion 132 better ensure that a plurality of positions of the matching protrusion 132 are at the same height, thus allowing the bottom cover 130 to be in exact fit with the matching protrusion 132 in different positions, so as to improve the fixed strength of the bottom cover 130 and the matching protrusion 132.
During embedment, it is required to fill the mounting portion 110 with glue. For the convenience of controlling the amount of glue filled by the operator, the mounting portion 110 may be provided with a glue identification portion 116 inside. The glue identification portion 116 may specifically have a strip-shaped protruding structure. When the glue filled reaches the glue identification portion 116, 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 portions 110 that are arranged side by side, so that a plurality of rows of lighting assemblies 200 can be provided. This involves connection between different mounting portions 110. For this, as illustrated in
To guarantee the appearance and the luminous effect of the lamp more reliably, the mounting portions 110 may be arranged at an equal distance from each other.
In a specific example, the mounting portions 110 may be connected by the mounting brackets 140 in pairs to form a plurality of sets of mounting portions 110. In this case, since each set of mounting portions 110 has 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 in
As illustrated in
At least a part of the plurality of mounting plates 142 are in snap fit with the mounting portion 110, so that the mounting portion 110 and the mounting bracket 140 are assembled together. In addition, at least a part of the mounting plates 142 may be fixed to the mounting portion 110 through second fastening components 172, thereby facilitating assembling and guaranteeing the assembly reliability. Specifically, a part of the mounting plates 142 may be in snap fit with the mounting portion 110, while the rest may be fixed to the mounting portion 110 through the second fastening components 172. Alternatively, a part of the mounting plates 142 may be in snap fit with the mounting portion 110 and also fixed to the mounting portion 110 through the second fastening components 172. To improve the mounting strength and facilitating manipulation, in this example of the present disclosure, the mounting plates 142 clamped with the same side of each mounting portion 110 are preferably fixed to the mounting portion 110 by means of the second fastening components 172, while the other mounting plates 142 are clamped with the mounting portion 110.
Based on the above examples, one of mounting plates located on the same side of the adjacent mounting grooves 143 is provided with a first bracket mounting hole 142a, while the other of the mounting plates located on the same side of the adjacent mounting grooves 143 is provided with a second bracket mounting hole 142b, and a distance between the first bracket mounting hole 142a and the main body plate 141 is greater than a distance between the second bracket mounting hole 142b and the main body plate 141. That is, there is a difference in height between the first bracket mounting hole 142a and the second bracket mounting hole 142b, thus preventing interference when the mounting portion 110 is mounted by the operator.
It should be noted that the above-mentioned “mounting plates located on the same side of the adjacent mounting grooves 143” refer to, among all the mounting plates 142 that form the adjacent mounting grooves 143, the mounting plates located on the same side of the mounting groove 143. Taking four mounting plates 142 as illustrated in
For facilitating wiring, a wire passing hole 141a is provided at a position, corresponding to a bottom of the separation groove 144, on the main body plate 141. That is, the wire passing hole 141a is communicated with the separation groove 144.
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.
