[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] Please also read Figures 1 to 4 Now, the lamp housing provided by the utility model is described. The lamp housing comprises a housing 1 and a light-transmitting plate 2. A protrusion 11 is provided on the inner side wall of the housing 1, and the protrusion 11 is distributed along the circumference of the housing 1; an abutment 21 extending upward and outward is provided on the top surface of the light-transmitting plate 2, and the abutment 21 is distributed along the circumference of the light-transmitting plate 2, and the abutment 21 is placed on the top surface of the protrusion 11; wherein, the bottom surface of the light-transmitting plate 2 is coplanar with the bottom surface of the housing 1.

[0039] It should be noted that the above-mentioned "top" and "bottom" are based on the direction of the lamp housing after it is installed on the installation object. After the lamp housing is installed, the side facing the installation object is the top, and the side away from the installation object is the bottom. The installation object can be a ceiling, a wall, a cabinet, etc.

[0040] The bottom surface of the shell 1 is an opening surface, and the light-transmitting plate 2 is installed at the opening surface. The cross section of the shell 1 is adapted to the structure of the light-transmitting plate 2 , so the light-transmitting plate 2 can block or nearly block the inner cavity of the shell 1 .

[0041] The shell 1 and the light-transmitting plate 2 may be circular, elliptical or other polygonal structures. The protrusion 11 is extended and distributed along the circumference of the shell 1. The protrusion 11 may be distributed in an integral ring around the circumference of the shell 1, or may be distributed in intervals and segments on the inner wall of the shell 1. Similarly, the abutment 21 is extended and distributed along the circumference of the light-transmitting plate 2. The abutment 21 may be distributed in an integral ring around the circumference of the light-transmitting plate 2, or may be distributed in intervals and segments on the top surface of the light-transmitting plate 2.

[0042] It should be noted that Figure 2 Only the light-transmitting plate 2 and the housing 1 are shown as rectangular structures. For the rectangular structure, in order to facilitate the installation of the light-transmitting plate 2 and increase the stability of the light-transmitting plate 2, the abutting portions 21 are arranged on the long edges of both sides of the top surface of the light-transmitting plate 2. If the light-transmitting plate 2 is a circular or other polygonal structure, the abutting portions 21 are preferably arranged on the outer edges of the top surface of the light-transmitting plate 2 and are distributed in intervals and sections.

[0043] Specifically, the abutting portion 21 is integrally formed with the light-transmitting plate 2, and the longitudinal section of the abutting portion 21 is a 7-shaped structure. Figure 3 As shown, the lateral part is overlapped and arranged on the top surface of the protruding part 11, and the vertical part can undergo a slight deformation to deflect toward the center of the light-transmitting plate 2 due to its smaller width.

[0044] When assembling the light-transmitting plate 2 and the shell 1, a part of the light-transmitting plate 2 can be firstly inserted into the shell 1, and the abutting portion 21 entering the shell 1 can be placed on the corresponding protrusion 11. Then, the light-transmitting plate 2 can be swung, and the abutting portion 21 that has not entered the shell 1 can be elastically pressed or squeezed, so that the abutting portion 21 is slightly deflected toward the center of the light-transmitting plate 2 and then snapped onto the corresponding protrusion 11.

[0045] Since the light-transmitting plate 2 needs to be deflected during installation, the outer diameter of the light-transmitting plate 2 should be slightly smaller than the inner diameter of the door opening of the shell 1 , that is, there should be a gap between the outer peripheral surface of the light-transmitting plate 2 and the bottom inner wall of the shell 1 .

[0046] Compared with the prior art, the lamp housing provided by the utility model is fixedly connected with the shell body 1 by overlapping the abutting portion 21 on the protruding portion 11. The abutting portion 21 and the protruding portion 11 are both hidden in the interior of the shell body 1, so that the bottom surface of the light-transmitting plate 2 and the bottom surface of the shell body 1 can be arranged on the same plane, and there is no height difference between the two, thereby making the overall appearance of the lamp housing beautiful; in addition, the abutting portion 21 overlaps with the protruding portion 11, and when the light-transmitting plate 2 is installed, the abutting portion 21 can be elastically pressed to cause the abutting portion 21 to be slightly deflected toward the center of the light-transmitting plate 2 to facilitate snap-fitting onto the protruding portion 11. The light-transmitting plate 2 is installed in a snap-fit ​​manner, so that the light-transmitting plate 2 and the shell body 1 can be designed in different shapes, thereby solving the problem of a single structure.

[0047] In some embodiments, the protrusion 11 and the abutment portion 21 may also be provided with Figure 3 The structure shown, see Figure 3 A limiting groove 22 is formed between the abutting portion 21 and the top surface of the light-transmitting plate 2 , and the protruding portion 11 is embedded in the limiting groove 22 . Preferably, the bottom surface of the protruding portion 11 abuts against the top surface of the light-transmitting plate 2 .

[0048] Since the longitudinal section of the abutment portion 21 is in a 7-shaped structure, the abutment portion 21 and the top surface of the light-transmitting plate 2 can form a limiting groove 22 with the notch facing the outer periphery of the light-transmitting plate 2, so that the protrusion 11 is embedded in the limiting groove 22, further increasing the clamping relationship. On the premise that the abutment portion 21 can be placed on the top surface of the protrusion 11, the abutment portion 21 and the protrusion 11 are limited in the up and down directions, thereby increasing the connection stability between the protrusion 11 and the abutment portion 21, and thereby improving the fixing strength of the light-transmitting plate 2.

[0049] Since the protrusion 11 is to be embedded in the limiting groove 22, the thickness of the protrusion 11 in the vertical direction must be adapted to the height of the limiting groove 22 in the vertical direction. In order to avoid the problem of difficulty in embedding due to dimensional error between the protrusion 11 and the limiting groove 22, please refer to Figure 3On the basis of the above embodiment, the protrusion 11 includes a first boss 111 and a second boss 112 spaced apart in the vertical direction, and a buffer groove 113 is formed between the first boss 111 and the second boss 112. The abutting portion 21 abuts against the top surface of the first boss 111.

[0050] The first boss 111 and the second boss 112 are spaced apart, and a buffer groove 113 is formed between the two, so that slight deformation in the up-down direction can occur between the first boss 111 and the second boss 112. When the abutting portion 21 presses the top surface of the first boss 111, the first boss 111 is embedded in the limiting groove 22. When the top surface of the light-transmitting plate 2 contacts the bottom surface of the second boss 112, the light-transmitting plate 2 also presses the second boss 112, and the second boss 112 is embedded in the limiting groove 22.

[0051] The buffer groove 113 provides a space for the protrusion 11 to deform slightly, so that when the light-transmitting plate 2 is assembled, the protrusion 11 can be conveniently inserted into the limiting groove 22 and the precision of the protrusion 11 can be simplified.

[0052] In some embodiments, the lamp housing may also be Figure 1 , Figure 2 and Figure 3 The structure shown, see Figure 1 , Figure 2 and Figure 3 The inner wall of the shell 1 is also provided with a mounting portion 12, which is located above the protruding portion 11 and extends along the circumferential direction of the shell 1; a sealing groove 13 is formed between the mounting portion 12 and the protruding portion 11, the upper end of the abutting portion 21 is located in the sealing groove 13, and a sealing strip 14 is squeezed between the top surface of the abutting portion 21 and the bottom surface of the mounting portion 12.

[0053] The sealing strip 14 is used to seal the light-transmitting plate 2 and the housing 1 to prevent impurities from entering the inner cavity of the housing 1 and contaminating the light source module 5 .

[0054] Specifically, the sealing strip 14 is bonded to the bottom surface of the mounting portion 12. When the light-transmitting plate 2 is assembled, the abutting portion 21 is inserted into the sealing groove 13, the lower surface of the lateral portion of the abutting portion 21 abuts against the top surface of the protruding portion 11, and the upper surface of the lateral portion of the abutting portion 21 presses the sealing strip 14. The sealing strip 14 is limited between the mounting portion 12 and the abutting portion 21 to achieve sealing.

[0055] Since the abutting portion 21 is inserted into the sealing groove 13 in a card-fitting manner, the sealing strip 14 will not be pushed or pulled, that is, the sealing strip 14 will not be curled or deformed at the end, thereby ensuring that the sealing strip 14 is in a stable state, thereby improving the sealing performance and service life of the sealing strip 14.

[0056] Preferably, on the basis of the above embodiment, the housing 1 is an annular structure, the protrusion 11 and the mounting portion 12 are respectively arranged around the inner wall of the housing 1 , and the sealing strip 14 is annularly arranged in the sealing groove 13 .

[0057] The protruding portion 11 and the mounting portion 12 are respectively annular structures, and the sealing strip 14 is also annular structure, which can facilitate the fixing of the sealing strip 14 and ensure good sealing performance between the housing 1 and the light-transmitting plate 2.

[0058] It should be noted that, in order to facilitate installation of the light-transmitting plate 2 and increase the stability of the light-transmitting plate 2 , the abutting portions 21 are preferably disposed on the outer edge of the top surface of the light-transmitting plate 2 and are distributed in intervals and sections.

[0059] In some embodiments, the lamp housing may also be Figure 2 The structure shown, see Figure 2 The lamp housing further comprises a back plate 3. The back plate 3 is fixedly arranged on the top surface of the mounting portion 12; the back plate 3, the housing 1 and the light-transmitting plate 2 form a closed mounting cavity, and the mounting cavity is used to assemble the light source module 5.

[0060] In addition to the lower end surface of the housing 1 being an open surface, the upper end surface is also an open surface to simplify the overall structure of the lamp housing, facilitate the processing and manufacturing of various components, and facilitate the assembly of the light source module 5. The back plate 3 is fixedly arranged on the upper end opening surface of the housing 1 (that is, fixed on the top surface of the mounting portion 12), and blocks the upper end opening surface. Preferably, a sealing strip is also provided between the back plate 3 and the mounting portion 12. The light source module 5 is fixedly arranged on the back plate 3.

[0061] See also Figure 4 In some embodiments, a step surface 121 is formed on the top surface of the mounting portion 12 , the outer peripheral edge of the back panel 3 is placed on the step surface 121 , and the outer peripheral edge of the back panel 3 is connected to the mounting portion 12 via a fastener 15 .

[0062] The outer peripheral edge of the back plate 3 is adapted to the structure of the step surface 121, that is, the outer peripheral edge of the back plate 3 is also a step structure, which can increase the connection area between the back plate 3 and the mounting portion 12, and can limit the back plate 3 and the shell 1 in the up and down directions of the lamp shell and in the radial direction of the lamp shell, thereby improving the stability of the fixation of the two.

[0063] In some embodiments, the mounting portion 12 may also be configured as follows: Figure 4 The structure shown, see Figure 4 The width of the mounting portion 12 protruding into the shell 1 is greater than the width of the protruding portion 11 protruding into the shell 1, so that the mounting portion 12 can form a step surface 121; and the mounting portion 12 has a weight-reducing cavity 122, which extends and distributes along the circumference of the mounting portion 12.

[0064] Specifically, the longitudinal section of the mounting portion 12 is similar to a triangular structure, the top surface of the mounting portion 12 is a step surface 121, the bottom surface is a plane, and the bottom surface and the step surface 121 are connected by an inclined surface. The longitudinal section of the weight-reducing cavity 122 is also similar to a triangular structure, and the weight-reducing cavity 122 can reduce the overall weight of the housing 1 and make the housing 1 easier to manufacture.

[0065] It should be noted that the mounting portion 12 and the protruding portion 11 are both integrally formed on the side wall of the housing 1 .

[0066] In some embodiments, the lamp housing may also be Figure 2 and Figure 6 The structure shown, see Figure 2 and Figure 6 The lamp housing further includes a fixing bracket 4. The fixing bracket 4 is plugged and arranged on the back plate 3 and is located above the back plate 3; the fixing bracket 4 is used to be fixed on the installation object.

[0067] Specifically, see Figure 5 A first plug-in slot 31 and a second plug-in slot 32 are provided on the back panel 3 at intervals, the notch of the first plug-in slot 31 faces the outer periphery of the back panel 3, and the notch direction of the first plug-in slot 31 is the same as the notch direction of the second plug-in slot 32; a first plug-in board 41 extending outward is provided at one end of the fixed bracket 4, and a second plug-in board 42 folded inward is provided at the other end, the first plug-in board 41 is plugged into the first plug-in slot 31, and the second plug-in board 42 is plugged into the second plug-in slot 32.

[0068] When assembling the fixing bracket 4 and the back panel 3, just push the fixing bracket 4 in one direction to insert the first plug-in board 41 into the first plug-in slot 31, and the second plug-in board 42 into the second plug-in slot 32. The connection method is simple and the assembly efficiency is high. There is no need to combine and fix multiple parts, which reduces the cost. In addition, the first plug-in board 41 is inserted into the first plug-in slot 31 and can cover the notch of the first plug-in slot 31. The second plug-in board 42 is inserted into the second plug-in slot 32 and can cover the notch of the second plug-in slot 32. It can also avoid the problem of holes on the exterior surface of the lamp housing.
