Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp body structure, a lamp provided with the lamp body structure, and a lighting system provided with the lamp. Background Art

[0002] An existing type of lamp (such as a downlight, a spotlight, etc.) includes a lamp body, a radiator, and other components. Figure 1 As shown, the lamp body 91 has a cavity 910 that runs through the lamp body 91, and the heat sink 92 is installed in the cavity 910. When the heat sink 92 and the lamp body 91 are assembled, the heat sink 92 is usually pressed into the cavity 910 of the lamp body 91 by riveting, so that the heat sink 92 and the inner circumferential wall of the cavity 910 are interference-fitted, thereby achieving fixation between the two. However, the existing assembly structure between the lamp body 91 and the heat sink 92 has the following deficiencies:

[0003] First, the assembly structure between the lamp body 91 and the heat sink 92 has very high requirements on the interference size; because when the assembly interference between the heat sink 92 and the lamp body 91 is too large, the wall of the lamp body 91 is prone to bulging, and when the assembly interference between the heat sink 92 and the lamp body 91 is too small, the assembly of the lamp body 91 and the heat sink 92 cannot pass the tensile test, that is, there is a risk of the heat sink 92 falling off the lamp body 91.

[0004] Second, the wall thickness of the lamp body 91 is high. The wall thickness of the lamp body 91 must not only meet the heat dissipation requirements, but also need to consider the problem of deformation and bulging that may occur during the assembly process with the radiator 92. When the wall thickness of the lamp body 91 is too thin, it is easy to deform and bulge when assembled with the radiator 92. Therefore, it is necessary to increase the wall thickness of the lamp body 91 to prevent deformation and bulging when assembled with the radiator 92. However, increasing the wall thickness of the lamp body 91 will not only increase the cost, but also easily affect the heat dissipation due to the excessive wall thickness of the lamp body 91. Summary of the invention

[0005] In order to solve the above problems, the main purpose of the utility model is to provide a lamp body structure which can improve the firmness of the assembly between the lamp body and the heat sink, prevent bulging on the wall of the lamp body after assembly, and does not increase the production cost.

[0006] Another object of the utility model is to provide a lamp having the above-mentioned lamp body structure.

[0007] Another object of the utility model is to provide a lighting system equipped with the above-mentioned lamp.

[0008] In order to achieve the main object of the present utility model, the present utility model provides a lamp body structure, which includes a lamp body and a radiator. The lamp body has a cavity that penetrates the lamp body in the height direction of the lamp body. Connecting columns extending in the height direction are provided on the inner wall of the cavity. The radiator is installed in the cavity and is in interference fit with the inner wall. The radiator has an avoidance groove that penetrates itself in the height direction, and the connecting column passes through the avoidance groove. Among them, an opening groove is provided on the connecting column, and an insertion block facing the opening groove is formed at the avoidance groove of the radiator. The insertion block is inserted into the opening groove and is in interference fit with the opening groove.

[0009] As can be seen from the above, by forming an interference fit connection between the insertion block on the radiator and the opening groove on the connecting column, the firmness of the assembly between the radiator and the lamp body can be improved. At the same time, the interference amount of the assembly between the radiator and the inner wall of the cavity of the lamp body can be reduced, thereby avoiding deformation and bulging after the lamp body and the radiator are assembled, and there is no need to increase the wall thickness of the lamp body, reducing costs. In addition, the opening groove on the connecting column can be formed together during the forming process of the lamp body without subsequent processing. Moreover, the forming of the insertion block can be carried out together during the press riveting assembly of the radiator and the lamp body and inserted into the opening groove, thereby reducing the processing difficulty and processing cost of the radiator.

[0010] A further solution is that in the projection along the height direction, the opening of the opening groove is arranged towards the middle of the cavity. An included angle is formed between the two first side walls of the opening groove, and the included angle is between 40° and 60°. The distance between the two first side walls is smaller closer to the axis of the connecting column, and the two first side walls are in interference fit with the insertion block.

[0011] As can be seen from the above, this design facilitates the insertion of the formed insertion block into the opening groove when the radiator and the lamp body are press riveted, so that the insertion block and the opening groove can have a reliable interference fit, ensuring the firmness of the assembly between the insertion block and the opening groove.

[0012] A further solution is that the insertion block is in the shape of a quasi-isosceles trapezoidal column or a quasi-isosceles triangular column, and one second side wall of the quasi-isosceles trapezoidal column or the quasi-isosceles triangular column is matched with and in interference fit with one first side wall.

[0013] As can be seen from the above, forming the insertion block into the shape of a quasi-isosceles trapezoidal column or a quasi-isosceles triangular column can make it more convenient for the insertion block to be inserted into the opening groove and ensure the firmness of the assembly between the insertion block and the two side walls of the opening groove.

[0014] A further solution is that the radiator has a bottom plate and a surrounding plate. An avoidance notch penetrating itself is provided on the bottom plate. The surrounding plate is located on one side of the bottom plate and surrounds the bottom plate along the contour of the bottom plate. The surrounding plate and the avoidance notch form the avoidance groove, and the insertion block is recessed and formed from the end of the surrounding plate away from the bottom plate towards the bottom plate in the height direction.

[0015] As can be seen from the above, through the design of the radiator, the forming of the radiator becomes more convenient. And through the design of the forming position of the insertion block, when the radiator and the lamp body are press-riveted and assembled, the forming of the insertion block is easier and the forming position is more reasonable.

[0016] A further solution is that the connecting column has a first connection hole penetrating the connecting column in the height direction, the opening groove penetrates the connecting column in the height direction, and the opening groove penetrates the hole wall of the first connection hole.

[0017] As can be seen from the above, this design makes the forming of the lamp body more convenient.

[0018] A further solution is that the bottom plate is provided with a second connection hole and a wire passing hole, and the second connection hole and the wire passing hole penetrate the bottom plate in the height direction; the lamp body is formed by an aluminum alloy material through an extrusion process, and the radiator is formed by an aluminum alloy material through a stamping process.

[0019] As can be seen from the above, the second connection hole can be used for a fastener to fix the light source assembly on the radiator to ensure the heat dissipation effect of the radiator on the light source assembly, and the wire passing hole can be used for the wire of the control unit to pass through the radiator and then be electrically connected to the light source assembly.

[0020] A further solution is that the number of connecting columns is between two and four, and each connecting column is provided with an opening groove; the number of the avoiding grooves is equal to the number of the connecting columns, and the number of the insertion blocks is less than or equal to the number of the connecting columns.

[0021] A further solution is that the tensile force between the lamp body and the radiator is between 300 Newtons and 380 Newtons.

[0022] As can be seen from the above, the above design can not only ensure the firmness of the assembly between the radiator and the lamp body, but also ensure the firmness of the assembly between the lamp body and other structures.

[0023] To achieve another object of the present invention, the present invention provides a lighting fixture, including a light source assembly, wherein, the lighting fixture further includes the above-mentioned lamp body structure, and the light source assembly is located in the cavity and installed on the radiator.

[0024] As can be seen from the above, for the lighting fixture provided with the above-mentioned lamp body structure, the firmness of the assembly between the lamp body and the radiator is strong, the lamp body is not easy to deform and bulge, and the production cost is lower and the weight is lighter.

[0025] To achieve another object of the present invention, the present invention provides an illumination system, including a control terminal, wherein, the illumination system further includes the above-mentioned lighting fixture, and the lighting fixture further includes a control unit, and the control unit is electrically connected to the light source assembly; the control terminal is electrically connected to the control unit, and / or the control terminal performs information interaction with the control unit.

[0026] As can be seen from the above, by setting the above-mentioned lamps, the lighting system has lower usage costs, better aesthetics, and stronger product structure stability and working stability. Description of the Drawings

[0032] The present invention will be further described below in conjunction with the drawings and embodiments. Detailed Embodiments

[0033] Embodiment of the Lamp Body Structure

[0034] Referring to Figure 2 and Figure 3 , the lamp body structure 100 includes a lamp body 1 and a radiator 2. Among them, the lamp body 1 is preferably made of aluminum alloy material, and the lamp body 1 is preferably formed by an extrusion process; the radiator 2 is preferably made of aluminum alloy material, and the radiator 2 is preferably formed by a stamping process.

[0035] Combined with Figure 4 , the lamp body 1 has a cavity 10. The cavity 10 penetrates the lamp body 1 in the height direction of the lamp body 1, and connecting columns 11 are provided on the inner wall of the cavity 10. The connecting columns 11 extend along the height direction of the lamp body 1. An opening groove 111 and a first connection hole 112 are provided on the connecting column 11. Preferably, both the opening groove 111 and the first connection hole 112 penetrate the connecting column 11 in the height direction to make the forming of the lamp body 1 more convenient; in addition, the opening groove 111 penetrates the hole wall of the first connection hole 112, so that the opening groove 111 communicates the first connection hole 112 with the cavity 10. More preferably, as shown in Figure 2 , in the projection along the height direction of the lamp body 1, the opening of the opening groove 111 faces the middle of the cavity 10.

[0036] The radiator 2 is installed in the cavity 10 of the lamp body 1, and the radiator 2 is in interference fit with the inner wall of the cavity 10, so that the radiator 2 can be fixed in the lamp body 1; wherein, the radiator 2 has an avoidance groove 20, and the avoidance groove 20 penetrates through the radiator 2 in the height direction of the lamp body 1. When the radiator 2 is installed in the cavity 10, the avoidance groove 20 can be penetrated by the connecting column 11 on the inner wall of the cavity 10 to avoid the connecting column 11.

[0037] In addition, the radiator 2 also has an insertion block 221, the insertion block 221 is formed at the avoidance groove 20, and the insertion block 221 is inserted into the opening groove 111 and is in interference fit with the opening groove 111. Among them, the insertion block 221 is preferably formed and inserted into the opening groove 111 during the press riveting assembly process of the radiator 2 and the lamp body 1, that is, the forming of the insertion block 221, the insertion of the insertion block 221 into the opening groove 111, and the interference fit treatment between the insertion block 221 and the opening groove 111 are completed at one time during the press riveting assembly process of the radiator 2 and the lamp body 1, effectively reducing the processing difficulty and processing cost of the radiator 2, and reducing the assembly difficulty and assembly process between the radiator 2 and the lamp body 1. At the same time, it can also prevent unnecessary deformation and damage of the connecting column 11 of the lamp body 1 during the assembly process. By forming the insertion block 221 on the radiator 2 and making the insertion block 221 in interference fit connection with the opening groove 111 on the connecting column 11, the firmness of the assembly between the radiator 2 and the lamp body 1 can be improved, and at the same time, the assembly interference amount between the radiator 2 and the inner wall of the cavity 10 of the lamp body 1 can be reduced, thereby avoiding deformation and bulging after the lamp body 1 and the radiator 2 are assembled, and the wall thickness of the lamp body 1 can be made thinner, reducing the cost and the weight of the lamp body structure 100.

[0038] The radiator 2 preferably has a bottom plate 21 and a surrounding plate 22. Among them, the bottom plate 21 is provided with an avoidance notch 211, a second connection hole 212 and a wire passing hole. The avoidance notch 211, the second connection hole 212 and the wire passing hole all penetrate through the bottom plate 21 in the height direction of the lamp body 1; the second connection hole 212 can be used for a fastener (such as a screw) to fix the light source assembly on the radiator 2 to ensure the heat dissipation effect of the radiator 2 on the light source assembly, and the wire passing hole can be used for the wire of the control unit to pass through the radiator 2 and then be electrically connected to the light source assembly. The surrounding plate 22 is located on one side of the bottom plate 21 and surrounds the bottom plate 21 along the contour of the bottom plate 21, so that the surrounding plate 22 and the avoidance notch 211 form the above-mentioned avoidance groove 20. Through the above design, the stamping forming of the radiator 2 is more convenient.

[0039] Combined with Figure 5, when the insert block 221 is formed, it is recessed from the end of the surrounding plate 22 away from the bottom plate 21 towards the bottom plate 21 in the height direction of the lamp body 1. This design makes it easier to form the insert block 221 and the forming position is more reasonable when the heat sink 2 and the lamp body 1 are press riveted and assembled. Preferably, in the projection along the height direction of the lamp body 1, an included angle is formed between the two first side walls 1111 of the opening groove 111, and the included angle a is between 40° and 60°, and the distance between the two first side walls 1111 becomes smaller as it approaches the axis of the connecting column 11. Among them, the two first side walls 1111 are in interference fit with the insert block 221. This design makes it convenient for the formed insert block 221 to be inserted into the opening groove 111 when the heat sink 2 and the lamp body 1 are press riveted and assembled, so that the insert block 221 and the opening groove 111 are in reliable interference fit and ensure the firmness of the assembly between the insert block 221 and the opening groove 111. More preferably, the insert block 221 is preferably in the shape of a quasi-isosceles trapezoidal column or a quasi-isosceles triangular column, and a second side wall 2211 of the quasi-isosceles trapezoidal column or the quasi-isosceles triangular column is in matching and interference fit with a first side wall 1111. Forming the insert block 221 into a quasi-isosceles trapezoidal column or a quasi-isosceles triangular column can make it more convenient for the insert block 221 to be inserted into the opening groove 111 and ensure the firmness of the assembly between the insert block 221 and the two side walls of the opening groove 111.

[0040] Furthermore, the number of the connecting columns 11 is preferably between two and four, and preferably an opening groove 111 is provided on each connecting column 11. The number of the avoidance grooves 20 is equal to the number of the connecting columns 11, and the number of the insert blocks 221 can be less than or equal to the number of the connecting columns 11. For example, in this embodiment, the number of the connecting columns 11 is three, an opening groove 111 is provided on each connecting column 11, the number of the insert blocks 221 is three, and the three insert blocks 221 correspond to the opening grooves 111 on the three connecting columns 11 one by one. This design can not only ensure the firmness of the assembly between the heat sink 2 and the lamp body 1, but also make the structures of the lamp body 1 and the heat sink 2 more optimized and reasonable, and can also ensure the firmness of the assembly between the lamp body 1 and other structures. Among them, the tensile force between the lamp body 1 and the heat sink 2 is preferably between 300 Newtons and 380 Newtons. Preferably, the tensile force between the lamp body 1 and the heat sink 2 is about 350 Newtons.

[0041] The following briefly describes the assembly of the lamp body 1 and the heat sink 2:

[0042] First, the heat sink 2 is pressed into the cavity 10 of the lamp body 1 through a press riveting die, so that the surrounding plate 22 of the heat sink 2 is in interference fit with the inner wall of the cavity 10. At this time, in order to prevent the wall of the lamp body 1 from deforming and bulging, the interference amount of the assembly between the heat sink 2 and the lamp body 1 cannot be too large. Therefore, the tensile force between the heat sink 2 and the lamp body 1 at this time still cannot meet the requirements.

[0043] Next, continue to perform riveting on the heat sink 2 with the riveting die, so that the end of the shroud 22 of the heat sink 2 away from the bottom plate 21 begins to deform at the avoidance groove 20 to form an insertion block 221. After the insertion block 221 is formed, the insertion block 221 is inserted into the opening groove 111 of the connecting column 11 to have an interference fit with the opening groove 111. At this time, under the dual action of the interference fit between the insertion block 221 and the opening groove 111 and the interference fit between the shroud 22 of the heat sink 2 and the inner wall of the cavity 10, the total assembly interference amount between the heat sink 2 and the lamp body 1 can ensure that the heat sink 2 and the lamp body 1 meet the anti-pulling requirements. Among them, the die for riveting and assembling the heat sink 2 and the lamp body 1 and the die for forming the insertion block 221 are the same set of dies. Therefore, the riveting assembly between the heat sink 2 and the lamp body 1 and the forming of the insertion block 221 can be completed successively within one set of processes, thus eliminating the need for additional processes.

[0044] In summary, the lamp body structure 100 provided by the present utility model utilizes the structural characteristics of the lamp body 1 and the heat sink 2 itself, and without increasing the processes and production materials, effectively improves the riveting force between the lamp body 1 and the heat sink 2, while not increasing the wall thickness of the lamp body 1, and can prevent the lamp body 1 from deforming and bulging after being assembled with the heat sink 2.
