Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lamp body assembly, a rail spotlight equipped with the lamp body assembly, and a lighting system equipped with the aforementioned rail spotlight. Background Technology

[0002] The existing rail spotlights mainly use the following two methods for assembling the lamp body and the back cover:

[0003] The first method involves fixing the back cover to the lamp body with screws. Usually, the connection between the back cover and the lamp body requires two to three screws. This fixing method requires workers to install each screw one by one, which increases labor costs, increases the cost of parts, and has low assembly efficiency.

[0004] The second method involves fixing the back cover to the lamp body using a snap-fit ​​structure. This method requires machining a groove on the lamp body to engage with the snap-fit ​​on the back cover. However, machining the lamp body adds an extra step and requires additional equipment, increasing production costs and hindering production efficiency. Summary of the Invention

[0005] To address the aforementioned problems, the main objective of this utility model is to provide a lamp body assembly that is easy and quick to assemble and has low cost.

[0006] Another objective of this invention is to provide a rail spotlight equipped with the aforementioned lamp body assembly.

[0007] Another objective of this invention is to provide a lighting system equipped with the aforementioned rail spotlights.

[0008] To achieve the main objective of this utility model, this utility model provides a lamp body assembly, including a lamp body and a rear cover. The lamp body has a cavity that extends through the lamp body in the height direction. A buckle is formed on the rear cover, and the protruding end of the buckle has a claw end protruding towards the inner peripheral wall of the cavity. The rear cover is inserted into the cavity and located at the tail end of the lamp body. The lamp body is formed by die casting. A step is formed on the inner peripheral wall of the cavity. The step has a step surface that faces the front end of the lamp body. The claw end is located between the front end of the lamp body and the step surface and is engaged with the step surface.

[0009] As can be seen from the above, the step for engaging with the snap-fit ​​on the back cover can be directly formed on the lamp body through die casting. This eliminates the need for further machining of the lamp body after forming, effectively reducing processing steps, lowering production costs, and improving production efficiency. The step surface is formed at the parting section of the die casting mold, eliminating the need for complex structures on the moving mold and / or fixed mold to form the step and step surface, thus reducing production costs. Furthermore, the snap-fit ​​connection between the step surface and the claw end of the snap-fit ​​on the back cover enables rapid assembly between the back cover and the lamp body, making the assembly of the back cover and the lamp body simpler, more convenient, and more efficient.

[0010] A further design is that the cavity has a first cavity and a second cavity, with the first cavity located near the tail end of the lamp body; the first cavity is in the shape of an inverted frustum, and the second cavity is in the shape of a frustum, with the small-diameter end of the first cavity connected to the small-diameter end of the second cavity to form a stepped surface.

[0011] As can be seen from the above, this design facilitates the demolding of the mold after the lamp body is formed, and also ensures the forming of the stepped surface, thereby ensuring the yield rate of lamp body production. In addition, the structural design of the first cavity also allows the cavity wall of the first cavity to guide the buckle when the back cover is installed on the lamp body, so that the claw end of the buckle can slide better to the stepped surface and cross the stepped surface, while also improving the fastening strength between the buckle and the step.

[0012] A preferred embodiment is that the second cavity has a mounting section formed therein, the mounting section including a mounting platform and multiple stiffening plates, the mounting platform having a receiving cavity with the opening of the receiving cavity facing the tail end of the lamp body, the multiple stiffening plates being distributed circumferentially along the mounting platform and extending along the height direction, the stiffening plates connecting the mounting platform and the inner peripheral wall of the second cavity.

[0013] As can be seen from the above, the mounting platform is used to provide installation space for light sources, lenses, light source brackets and / or lens brackets, etc. The forming of a cavity on the mounting platform helps to reduce the weight and cost of the lamp body, and at the same time helps to improve the heat dissipation effect of the lamp body on light source and other components. In addition, the cavity can also be used to accommodate other components (such as control modules). The stiffening plate, in addition to fixing the mounting platform in the second cavity, can also improve the heat dissipation effect of the lamp body on light source and other components.

[0014] A further option is to form a set of limiting ribs on the back cover, with the limiting ribs extending toward the front end of the lamp body in the height direction, and the end face of the extended end of the limiting ribs adjacent to the rib plate.

[0015] As can be seen from the above, the limiting rib group can work with the rib plate to limit the back cover, so as to prevent the back cover from moving excessively into the lamp body, thereby ensuring that the claw end of the buckle and the step surface can be reliably fastened together; in addition, the design of the limiting rib group is also conducive to reducing the material and weight of the back cover, thereby reducing the production cost of the back cover.

[0016] A further improvement is that the end face of the rib plate near the step surface is flush with the step surface; each buckle is formed with a limiting rib group, which includes a first limiting rib and a second limiting rib, and the buckle is located between the first limiting rib and the second limiting rib; there is a first connecting part between the fixed end of the buckle and the fixed end of the first limiting rib, a second connecting part between the fixed end of the buckle and the fixed end of the second limiting rib, a first gap between the free end of the buckle and the free end of the first limiting rib, and a second gap between the free end of the buckle and the free end of the second limiting rib.

[0017] As can be seen from the above, the design enables the first and second limiting ribs to increase the structural strength of the buckle and prevent the fixed end of the buckle from easily breaking. It also prevents the first and second limiting ribs from restricting the elastic deformation of the buckle, so as to ensure that the claw end of the buckle can reliably engage with the step surface.

[0018] Another preferred design is that the lamp body is shaped like a frustum, with the smaller diameter end of the lamp body being the tail end and the larger diameter end being the front end.

[0019] As can be seen from the above, this design facilitates the demolding of the mold after the lamp body is formed.

[0020] Another preferred embodiment is that a first clearance notch is formed at the tail end of the lamp body, and the first clearance notch penetrates the wall of the first cavity; the rear cover is also formed with a second clearance notch and a heat dissipation groove, the second clearance notch matches the first clearance notch, and the heat dissipation groove communicates with the first cavity.

[0021] As can be seen from the above, the first and second clearance notches are used to accommodate and avoid the connecting rod of the rail spotlight, which helps to improve the aesthetics of the rail spotlight equipped with this lamp body assembly and reduce the space required by the rail spotlight; while the design of the heat dissipation groove on the rear cover helps to improve the heat dissipation effect of the lamp body assembly on the light source and other components.

[0022] A further option is to make the lamp body from aluminum alloy or zinc alloy; the back cover is formed by injection molding.

[0023] As can be seen from the above, the lamp body made of aluminum alloy or zinc alloy can ensure the heat dissipation effect of components such as the light source; while the injection molding process for molding the back cover allows for the precise molding of each functional structure on the back cover, reducing the molding difficulty and molding cost of each functional structure on the back cover.

[0024] To achieve another objective of this utility model, this utility model provides a rail spotlight, which includes the above-mentioned lamp body assembly.

[0025] As can be seen from the above, the rail spotlight with the above-mentioned lamp body components is easier, more convenient and faster to assemble, which helps to improve assembly efficiency and reduce production costs.

[0026] To achieve another objective of this utility model, this utility model provides a lighting system, including a control terminal, wherein the lighting system further includes the aforementioned rail spotlights; the control terminal is electrically connected to the rail spotlights, and / or the control terminal interacts with the rail spotlights.

[0027] As can be seen from the above, by installing the aforementioned rail spotlights, the lighting system can reduce its usage and maintenance costs. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0034] Rail spotlight example

[0035] Reference Figure 1 The rail spotlight 100 includes a lamp body assembly 101, a power supply box 102, a connecting rod 103, and a light source (not shown). The lamp body assembly 101 includes a lamp body 1 and a rear cover 2. The light source is located inside the lamp body 1 and electrically connected to the power supply box 102. The first end of the connecting rod 103 is hinged to the power supply box 102, so that the lamp body assembly 101 can rotate circumferentially around the hinge axis between the connecting rod 103 and the power supply box 102, thereby realizing the circumferential illumination angle adjustment of the rail spotlight 100. The second end of the connecting rod 103 is connected to the lamp body 1 through a connecting bracket (not shown), so that the lamp body assembly 101 can pitch and rotate relative to the hinge axis between the connecting rod 103 and the connecting bracket, thereby realizing the pitch illumination angle adjustment of the rail spotlight 100.

[0036] Combination Figure 2 and Figure 3The lamp body 1 has a cavity 11 that extends through the lamp body 1 along its height. The lamp body 1 is formed using a die-casting process, resulting in a step 111 forming on the inner circumferential wall of the cavity 11. This step 111 has a step surface 1111, which faces the front end (i.e., the light-emitting end) of the lamp body 1. By using die-casting to manufacture the lamp body 1, the step 111 for engaging with the snap 21 on the rear cover 2 can be directly formed on the lamp body 1. Therefore, no further machining of the lamp body 1 is required after its formation, effectively reducing processing steps, lowering production costs, and improving production efficiency.

[0037] Preferably, the cavity 11 has a first cavity 112 and a second cavity 113. The first cavity 112 is located near the tail end of the lamp body 1 and is shaped like an inverted frustum. The second cavity 113 is shaped like a frustum of a cone, and the smaller diameter end of the first cavity 112 is connected to the smaller diameter end of the second cavity 113, forming a stepped surface 1111 between them. The shape design of the first cavity 112 and the second cavity 113 makes demolding of the lamp body 1 easier after molding, improving the yield rate of lamp body 1 production. Simultaneously, this design places the stepped surface 1111 at the parting section of the die-casting mold, eliminating the need for complex structures on the moving mold and / or fixed mold of the lamp body 1 to form the step 111 and the stepped surface 1111, reducing production costs and ensuring the smooth molding of the stepped surface 1111. The shape design of the first cavity 112 also facilitates the installation of the back cover 2 onto the lamp body 1, so that the cavity wall of the first cavity 112 guides the buckle 21 on the back cover 2, so that the claw end 211 of the buckle 21 slides better onto the step surface 1111 and passes over the step surface 1111, while also improving the fastening strength between the buckle 21 and the step 111.

[0038] The second cavity 113 contains a mounting section 114, which includes a mounting platform 1141 and multiple reinforcing ribs 1142. The mounting platform 1141 has a receiving cavity 11411, with the opening of the receiving cavity 11411 facing the rear end of the lamp body 1. This allows the bottom wall of the receiving cavity 11411 to provide mounting space for light sources, lenses, light source supports, and / or lens supports. The forming of the receiving cavity 11411 helps reduce the weight and cost of the lamp body 1, while also improving the heat dissipation effect of the lamp body 1 on components such as the light source. Furthermore, the receiving cavity 11411 can also be used to accommodate other components (such as control modules).

[0039] Multiple stiffening plates 1142 are distributed circumferentially along the mounting platform 1141, extending along the height direction, and connecting the mounting platform 1141 and the inner peripheral wall of the second cavity 113. The stiffening plates 1142 are used to fix the mounting platform 1141 within the second cavity 113, and their arrangement improves the heat dissipation effect of the lamp body 1 on components such as the light source. Preferably, the end face of the stiffening plate 1142 near the step surface 1111 is flush with the step surface 1111 to facilitate the forming of the lamp body 1. Furthermore, the lamp body 1 is frustum-shaped, with the smaller diameter end of the lamp body 1 being the tail end and the larger diameter end being the front end. This design also facilitates demolding of the lamp body 1 after forming.

[0040] Combination Figure 4 and Figure 5 The rear cover 2 is formed with a buckle 21, a limiting rib group 22, a second clearance opening, and a heat dissipation groove 24. The buckle 21 extends towards the front end of the lamp body 1 in the height direction, and the protruding end of the buckle 21 has a claw end 211, which protrudes towards the inner peripheral wall of the first cavity 112 of the cavity 11. When the rear cover 2 is assembled with the lamp body 1, the rear cover 2 is inserted into the first cavity 112 of the cavity 11. At this time, the rear cover 2 is located at the rear end of the lamp body 1, and the claw end 211 is located between the front end of the lamp body 1 and the step surface 1111, and the claw end 211 is engaged with the step surface 1111. The rear cover 2 is connected to the step 111 on the lamp body 1 by the buckle 21, which can realize the quick assembly between the rear cover 2 and the lamp body 1, thus making the assembly of the rear cover 2 and the lamp body 1 simpler, more convenient, and more efficient.

[0041] The limiting rib assembly 22 extends towards the front end of the lamp body 1 in the height direction. When the rear cover 2 is assembled onto the lamp body 1, the extended end face of the limiting rib assembly 22 is adjacent to the rib plate 1142. The limiting rib assembly 22 is used to cooperate with the rib plate 1142 to limit the rear cover 2, so as to prevent the rear cover 2 from moving excessively into the lamp body 1. At the same time, it can also ensure that the claw end 211 of the buckle 21 is reliably engaged with the step surface 1111. In addition, the design of the limiting rib assembly 22 also helps to reduce the material and weight of the rear cover 2, thereby reducing the production cost of the rear cover 2.

[0042] Preferably, the limiting rib group 22 is formed at each buckle 21, and the limiting rib group 22 preferably includes a first limiting rib 221 and a second limiting rib 222, with the buckle 21 located between the first limiting rib 221 and the second limiting rib 222. More preferably, a first connecting portion 2211 is provided between the fixed end of the buckle 21 and the fixed end of the first limiting rib 221, and a first gap w1 is provided between the free end of the buckle 21 and the free end of the first limiting rib 221; a second connecting portion 2221 is provided between the fixed end of the buckle 21 and the fixed end of the second limiting rib 222, and a second gap w2 is provided between the free end of the buckle 21 and the free end of the second limiting rib 222.

[0043] By designing the limiting rib group 22 and the first connecting part 2211 and the second connecting part 2221, the structural strength of the buckle 21 is enhanced, thereby preventing the fixed end of the buckle 21 from breaking. The design of the first gap w1 and the second gap w2 prevents the first limiting rib 221 and the second limiting rib 222 from restricting the elastic deformation of the buckle 21, thus ensuring that the claw end 211 of the buckle 21 can reliably engage with the stepped surface 1111. When the rear cover 2 is assembled onto the lamp body 1, the protruding end face of the first limiting rib 221 and / or the protruding end face of the second limiting rib 222 is adjacent to the rib plate 1142; preferably, both the protruding end faces of the first limiting rib 221 and the protruding end faces of the second limiting rib 222 are adjacent to the rib plate 1142.

[0044] In addition, a first clearance notch 1121 is formed at the tail end of the lamp body 1. The first clearance notch 1121 penetrates the wall of the first cavity 112. The first clearance notch 1121 matches the second clearance notch 23 of the rear cover 2. Both are used to accommodate and avoid the connecting rod 103, so that the connecting rod 103 can pass through the lamp body 1 and the rear cover 2 and connect with the connecting bracket. This design allows the connecting bracket to be placed inside the lamp body assembly 101, improving the aesthetics of the rail spotlight 100 equipped with this lamp body assembly 101 and reducing the space required by the rail spotlight 100.

[0045] The heat dissipation groove 24 is connected to the first cavity 112. The arrangement of the heat dissipation groove 24 helps to improve the heat dissipation effect of the lamp body assembly 101 on components such as the light source. Furthermore, the lamp body 1 is preferably made of aluminum alloy to ensure that the lamp body 1 can ensure the heat dissipation effect on components such as the light source; of course, as another optional solution, the lamp body 1 can also be made of zinc alloy. Moreover, the back cover 2 is formed by injection molding process so that the various functional structures on the back cover 2 can be precisely formed, and the forming difficulty and forming cost of the various functional structures on the back cover 2 can be reduced.

[0046] In summary, the design of the rail spotlight 100 and its lamp body assembly 101 makes the assembly of the rail spotlight 100 simpler, more convenient, and faster, which helps to improve assembly efficiency and reduce production costs.
