Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and particularly relates to a downlight with an integrated lamp body. Background Art

[0002] Downlights are commonly used lighting fixtures. Referring to Figure 1 , current downlights mainly consist of a housing 11, a reflector cup 12, a diffuser plate 13, a light source board 14, an upper cover plate 15, and a power supply assembly 16. The reflector cup 12 and the diffuser plate 13 are installed inside the housing 11. The reflector cup 12 and the housing 11 clamp the upper and lower sides of the diffuser plate 13. The light source board 14 is installed on the reflector cup 12. When processing the housing and the reflector cup, there is a lot of material loss, the part processing cost is relatively high, and there are many steps in the assembly process, resulting in low assembly efficiency.

[0003] In addition, the power supply assembly 16 is fixed to the upper cover plate 15 by screws 17 from the inside of the upper cover plate 15, and the screws are exposed on the upper side of the upper cover plate 15. However, the waterproof sealing performance of the connection thread between the screw and the upper cover plate is not high, and water may enter the inside of the downlight and cause damage. In order to achieve a high waterproof level, it is necessary to apply glue at the screw, which results in slow installation efficiency and there is still a risk of water ingress when the gluing is poor. Summary of the Utility Model

[0004] The main purpose of the present utility model is to propose a downlight with an integrated lamp body, aiming to solve the technical problems in the prior art that the downlight includes a housing and a reflector cup, with a lot of material loss during the processing of the housing and the reflector cup, relatively high part processing cost, many steps in the assembly process, and low assembly efficiency.

[0005] To achieve the above purpose, the present utility model proposes a downlight with an integrated lamp body, including a lamp body formed by one-piece stamping. The lamp body includes a cylindrical outer shell plate, a horizontal plate and a cup-shaped reflective side plate are provided inside the outer shell plate. The horizontal plate is arranged in the middle of the upper side of the reflective side plate. The outer periphery of the horizontal plate is connected to the upper side of the reflective side plate. The lower side of the reflective side plate is connected to the lower side of the outer shell plate. A clamping part is provided on the inner side wall of the reflective side plate. The downlight further includes a diffuser plate and a light source board. The light source board is fixedly connected to the lower side of the horizontal plate. The diffuser plate is arranged below the light source board. The diffuser plate is clamped and fixed to the clamping part.

[0006] The lamp body of this downlight is formed by one-piece stamping to produce the outer shell plate, the reflective side plate and the horizontal plate. The diffuser plate is clamped to the clamping part of the reflective side plate. The outer shell plate is equivalent to the housing of the existing downlight, and the reflective side plate and the horizontal plate are equivalent to the reflector cup of the existing downlight. In this way, the number of processed parts can be reduced, the material loss during the forming of the lamp body can be reduced, and the processing cost can be lowered. The assembly steps can be reduced during assembly, and the assembly efficiency can be improved.

[0007] Preferably, the clamping portion is a clamping groove arranged in a circumferential ring shape, and the outer edge of the diffuser plate is clamped in the clamping groove.

[0008] An annular clamping groove is arranged on the inner side of the reflective side plate, and the outer edge of the diffusion plate is clamped in the clamping groove, so as to facilitate the installation and fixation of the diffusion plate.

[0009] Preferably, the reflective side plate is tilted inward from bottom to top, the card slot is integrally stamped with the reflective side plate, the cross section of the card slot is arc-shaped, and the outer edge of the upper side of the diffuser plate is rounded.

[0010] Due to the inclined setting of the reflective side panel, the slot can be formed simultaneously when the lamp body is stamped, and the processing is simple; however, since the slot is formed by stamping, it is limited by the process and cannot be processed too deep, otherwise the undercut mold for forming the slot cannot be withdrawn, so the depth of the slot can only be made shallow, which will affect the clamping stability of the diffuser plate. Therefore, this scheme sets a rounded corner on the outer edge of the upper side of the diffuser plate. The setting of the rounded corner makes the outer edge of the upper side of the diffuser plate more adaptable to the arc shape of the slot, so that the lower side of the diffuser plate can be more embedded in the slot, thereby making the clamping of the diffuser plate and the slot more stable.

[0011] Preferably, the depth of the card slot is 0.8-1.2 mm, the thickness of the diffusion plate is 0.8-1.2 mm, and the radius of the fillet is 0.5-0.7 mm.

[0012] Preferably, the downlight also includes a metal cover and a power supply assembly, the metal cover is arranged on the upper side of the lamp body, the metal cover is detachably connected to the outer shell plate, a rivet nut is provided on the metal cover, the rivet nut includes a rivet plate and a mounting nut, the rivet plate is riveted and fixed to the upper side of the metal cover, the mounting nut is arranged on the lower side of the metal cover, the power supply assembly is arranged on the lower side of the metal cover, a mounting hole is provided on the power supply assembly, the mounting hole and the mounting nut are connected by mounting screws so that the power supply assembly is installed on the lower side of the metal cover.

[0013] The metal cover is stamped and riveted with a rivet nut, and the mounting nut of the rivet nut is on the lower side of the metal cover. The mounting screw passes through the mounting hole of the power supply assembly and is threadedly connected and locked with the mounting nut to achieve the installation of the power supply assembly on the lower side of the metal cover. In this solution, the rivet plate of the rivet nut is riveted to the metal cover, and the mounting screw is connected to the mounting nut of the rivet nut inside the downlight. The mounting screw does not need to pass through the metal cover, and the waterproof sealing is better, and no glue is required, which can improve the installation efficiency.

[0014] Preferably, a spray coating is provided on the upper sides of the metal cover plate and the rivet nut.

[0015] The spray coating layer can further improve the waterproof and airtight performance at the riveting connection position between the metal cover plate and the rivet nut, and enhance the aesthetic property of the downlight.

[0016] Preferably, a connecting plate is provided on the lower side of the outer periphery of the metal cover plate. The connecting plate is arranged on the outer periphery of the outer shell plate and is fixedly connected to the outer shell plate by a first screw.

[0017] Preferably, the light source plate is fixedly connected to the transverse plate by a second screw. Description of the Drawings

[0031] As Figures 3 to 7 shown, a downlight with an integrated lamp body includes a lamp body 2 formed by integral stamping. The lamp body 2 includes a cylindrical outer shell plate 21. Inside the outer shell plate 21, there are a horizontal plate 22 and a cup-shaped reflective side plate 23. The horizontal plate 22 is arranged in the middle of the upper side of the reflective side plate 23. The outer periphery of the horizontal plate 22 is connected to the upper side of the reflective side plate 23. The lower side of the reflective side plate 23 is connected to the lower side of the outer shell plate 21. A clamping portion is provided on the inner side wall of the reflective side plate 23. The downlight further includes a diffuser plate 3 and a light source plate 4. The light source plate 4 is fixedly connected to the lower side of the horizontal plate 22. The diffuser plate 3 is arranged below the light source plate 4. The diffuser plate 3 is fixedly connected to the clamping portion by clamping.

[0032] The lamp body 2 of the present downlight is formed into an outer shell plate 21, a reflective side plate 23 and a horizontal plate 22 through an integrated stamping process. The diffuser plate 3 is connected to the clamping part of the reflective side plate 23. The outer shell plate 21 is equivalent to the shell of the existing downlight, and the reflective side plate 23 and the horizontal plate 22 are equivalent to the reflective cup of the existing downlight. This can reduce the number of processed parts, reduce the material loss of the lamp body 2 molding and reduce the processing cost. In addition, compared with the prior art, which requires the assembly of the shell and the reflective cup, and the diffuser plate is clamped between the shell and the reflective cup, the present solution can reduce the assembly steps during assembly. During installation, the light source plate 4 is first installed on the horizontal plate 22, and then the diffuser plate 3 is installed on the reflective side plate 23, thereby improving the assembly efficiency. The shape of the cup-shaped reflective side plate 23 can be set with reference to the shape of the existing reflective cup.

[0033] In some specific embodiments, referring to Figures 4 to 6 The clamping portion is a clamping groove 231 arranged in a circumferential annular direction, and the outer edge of the diffuser plate 3 is clamped in the clamping groove 231 .

[0034] An annular clamping groove 231 is provided on the inner side of the reflective side plate 23 , and the outer edge of the diffuser plate 3 is clamped in the clamping groove 231 , so as to facilitate the installation and fixation of the diffuser plate 3 .

[0035] Furthermore, the reflective side plate 23 is tilted inward from bottom to top, the slot 231 is integrally stamped with the reflective side plate 23 , the cross section of the slot 231 is arc-shaped, and the outer edge of the upper side of the diffuser plate 3 is provided with a rounded corner 31 .

[0036] Due to the inclined setting of the reflective side plate 23, the slot 231 can be formed simultaneously when the lamp body 2 is stamped, and the processing is simple; however, since the slot 231 is formed when the lamp body 2 is stamped, due to the limitation of the process, the slot 231 cannot be processed too deep, otherwise the undercut mold for forming the slot 231 cannot be withdrawn, so the depth of the slot 231 can only be made shallow. If a conventional diffuser plate 3 is used, that is, the outer edge of the upper side of the diffuser plate 3 is not provided with a rounded corner 31, the outer edge of the upper side of the diffuser plate 3 will support the slot 231, causing the depth of the diffuser plate 3 embedded in the slot 231 to be shallow, which will affect the clamping stability of the diffuser plate 3. Therefore, the present scheme sets a rounded corner 31 on the outer edge of the upper side of the diffuser plate 3. The setting of the rounded corner 31 allows the outer edge of the upper side of the diffuser plate 3 to be more adapted to the arc shape of the slot 231, so that the lower side of the diffuser plate 3 can be more embedded in the slot 231, thereby making the clamping of the diffuser plate 3 and the slot 231 more stable.

[0037] Furthermore, the depth of the slot 231 is 0.8-1.2 mm, the thickness of the diffuser plate 3 is 0.8-1.2 mm, and the radius of the fillet 31 is 0.5-0.7 mm. Within the above numerical range, the slot 231 is easier to process and the diffuser plate 3 is more firmly installed.

[0038] In some specific embodiments, referring toFigure 3 , Figure 5 and Figure 7 , the downlight further includes a metal cover plate 5 and a power supply assembly 6. The power supply assembly 6 is electrically connected to the light source board 4. The metal cover plate 5 is disposed on the upper side of the lamp body 2. The metal cover plate 5 is detachably connected to the outer shell plate 21. A rivet nut 51 is provided on the metal cover plate 5. The rivet nut 51 includes a rivet plate 511 and a mounting nut 512. The rivet plate 511 is riveted and fixed to the upper side of the metal cover plate 5. The mounting nut 512 is disposed on the lower side of the metal cover plate 5. The power supply assembly 6 is disposed on the lower side of the metal cover plate 5. An installation hole 61 is provided on the power supply assembly 6. The installation hole 61 and the mounting nut 512 are connected by an installation screw 53 so that the power supply assembly 6 is installed on the lower side of the metal cover plate 5.

[0039] The rivet nut 51 is stamped and riveted on the metal cover plate 5. The mounting nut 512 of the rivet nut 51 is on the lower side of the metal cover plate 5. When riveting, a through hole is provided on the metal cover plate 5. The mounting nut 512 passes through the through hole. The rivet plate 511 is larger than the diameter of the through hole. The rivet plate 511 is on the upper side of the through hole. By pressing on the rivet plate 511 with a stamping device, the rivet plate 511 is pressed into the metal cover plate 5 for riveting and fixing. The power supply assembly 6 is installed on the lower side of the metal cover plate 5 by passing the installation screw 53 through the installation hole 61 of the power supply assembly 6 and threadedly connecting and locking with the mounting nut 512. In this solution, the rivet plate 511 of the rivet nut 51 is riveted to the metal cover plate 5. The installation screw 53 is connected to the mounting nut 512 of the rivet nut 51 inside the downlight. The installation screw 53 does not need to pass through the metal cover plate 5, so the waterproof and airtight performance is good, and no glue needs to be applied, which can improve the installation efficiency.

[0040] Furthermore, a spray coating is provided on the upper sides of the metal cover plate 5 and the rivet nut 51.

[0041] After the metal cover plate 5 and the rivet nut 51 are riveted, an electrostatic spray coating is formed. The spray coating can further improve the waterproof and airtight performance of the riveted connection position of the metal cover plate 5 and the rivet nut 51, and improve the aesthetics of the downlight.

[0042] In some specific embodiments, a connecting plate 52 is provided on the lower side of the outer periphery of the metal cover plate 5. The connecting plate 52 is disposed on the outer periphery of the outer shell plate 21. The connecting plate 52 is fixedly connected to the outer shell plate 21 by a first screw 54, which facilitates the installation and fixation of the metal cover plate 5 and the outer shell plate 21. The light source board 4 is fixedly connected to the cross plate 22 by a second screw, which facilitates the installation of the light source board 4.

[0043] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
