DETAILED DESCRIPTION



[0024] In order to make the objectives, technical solutions and advantages of the present disclosure more comprehensible, the present disclosure is further described in detail hereinbelow with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein intended only to interpret the present application and are not intended to limit the present application.

[0025] An embodiment of the present application provides a surface-mount downlight.

[0026] Please refer to FIGS. 1 to 4, the surface-mount downlight includes a downlight body 100 and a mounting top plate 200.

[0027] The downlight body 100 includes a cylindrical body 110 having a cylindrical shape, a light source module 130 configured for generating light and located in the cylindrical body 110, and at least two fixing blocks 120 connected to the inner wall surface of the cylindrical body 110 and all located at the same horizontal position.

[0028] The mounting top plate 200 is fixed connected to a ceiling, that is, the installation of the surface-mount downlight may be completed once the downlight body 100 is connected to the mounting top plate 200. The mounting top plate 200 may be capable of entering into the cylindrical body 110 and rotating with respect to the cylindrical body 110. The mounting top plate 200 includes a base plate 210 connected to the ceiling and at least two connecting plates 220 disposed at the peripheral side of the base plate 210 and extending circumferentially, each connecting plate 220 includes a connecting portion 221 and a hanging portion 222 connected to the connecting portion 221. The mounting top plate 200 has a first and second position with respect to the downlight body 100. In the first position, the mounting top plate 200 and the downlight body 100 avoid each other so that the mounting top plate 200 is able to enter and exit the cylindrical body 110, and in the second position, the at least two connecting plates 220 are respectively mounted with a fixing block 120 to restrict the mounting top plate 200 from entering and exiting the cylindrical body 110. A rotation of the mounting top plate 200 with respect to the downlight body 100 enables a switch between the first position and the second position.

[0029] In this embodiment, the extending direction of each hanging portion 222 may be clockwise, and then the mounting top plate 200 rotates clockwise with respect to the downlight body 100 to switch from the first position to the second position.

[0030] During installation, first installing the mounting top plate 200 to the ceiling, where the mounting top plate 200 is lighter in weight with respect to the entire surface-mount downlight, and the installation of the mounting top plate 200 is relatively simple, and then lifting the downlight body 100 so that the mounting top plate 200 enters into the cylindrical body 110, the horizontal position of the end of the hanging portion 222 facing away from the connecting portion 221 is lower than that of the fixing block 120, and the end of each hanging portion 222 facing away from the connecting portion 221 is located at the rear side of the corresponding fixing block 120 in the clockwise direction, and finally, rotating the downlight body 100 counterclockwise, that is, the mounting top plate 200 is rotated clockwise with respect to the downlight body 100, such that each of the fixing blocks 120 is mounted above the hanging portion 222 thereby connecting the downlight body 100 to the mounting top plate 200, and thus the installation of the surface-mount downlight is completed.

[0031] It can be seen from the above that based on the structural design of the present application, the surface-mount downlight is divided into two parts, one part is the lighter mounting top plate 200, and the other is the heavier downlight main body 100. During the installation process, when installing the mounting top plate 200, there is no need to lift the heavier downlight body 100, and when installing the downlight body 100, it only requires lifting the downlight body 100 to make the mounting top plate 200 being placed into the cylindrical body 110, then rotating the downlight body 100 to complete the installation of the surface-mount downlight, such that the supporting time by the staff is reduced which is helpful to reduce the difficulty of installation by the staff.

[0032] In other embodiments, the extending direction of each hanging portion 222 may be counterclockwise, and the mounting top plate 200 rotates counterclockwise with respect to the downlight body 100 to switch from the first position to the second position.

[0033] Based on this, during installation, first installing the mounting top plate 200 to the ceiling, where the mounting top plate 200 is lighter in weight with respect to the entire surface-mount downlight, and the installation of the mounting top plate 200 is relatively simple, and then lifting the downlight body 100 so that the mounting top plate 200 enters into the cylindrical body 110, the horizontal position of the end of the hanging portion 222 facing away from the connecting portion 221 is lower than that of the fixing block 120, and the end of each hanging portion 222 facing away from the connecting portion 221 is located at the rear side of the corresponding fixing block 120 in the counterclockwise direction, and finally, rotating the downlight body 100 clockwise, that is, the mounting top plate 200 is rotated clockwise with respect to the downlight body 100, such that each of the fixing blocks 120 is mounted above the hanging portion 222 thereby connecting the downlight body 100 to the mounting top plate 200, and thus the installation of the surface-mount downlight is completed.

[0034] Please refer to FIGS. 1 to 4. In the embodiment of the present application, the hanging portion 222 is also inclined downward, so that the height required for the downlight body 100 to be lifted is favorably reduced.

[0035] In addition, based on this structure, in the process of rotating the fixing block 120 onto the hanging portion 222, the fixing block 120 is gradually raised under the guidance of the hanging portion 222, and then in combination with the actual application, where the upper side of the mounting top plate 200 is connected to the ceiling, the upper side of the cylindrical body 110 will contact against the ceiling, meanwhile, the static friction between the fixing block 120 and the hanging portion 222 may be increased, it thus is beneficial to prevent the downlight body 100 from detaching from the mounting top plate 200.

[0036] Please refer to FIGS. 1 to 4. In the embodiment of the present application, the connecting plate 220 includes a guide portion 223 which is connected to the end of the hanging portion 222 that faces away from the connecting portion 221, and the guide portion 223 is horizontally arranged. It can be seen from the above that during the process of rotating the fixing block 120 onto the hanging portion 222, it is necessary to support the downlight body 100 when applying a rotating force to the downlight body 100, and meanwhile, it would be necessary to increase the rotating force for rotating the downlight body 100 due to the upper side of the cylindrical body 110 contacts against the ceiling. Based on this structure, where the fixing block 120 is placed on the guide portion 223 before rotating the downlight body 100. Such that the fixing block 120 is placed on the guide portion 223 without excessive rotating force, and when it is rotated onto the hanging portion 222, it does not need to support the downlight body 100, thus it is helpful for reducing the difficulty of installing the downlight body 100.

[0037] Please refer to FIGS. 1 to 4, the number of the fixing blocks 120 is larger than the number of the connecting plates 220, and each connecting plate 220 is respectively mounted with a fixing block 120 when the mounting top plate 200 is in the second position. In this way, in actual use, each fixing block 120 only needs to be mounted to a connecting plate 220, which is beneficial to improve the connection efficiency.

[0038] Please refer to FIGS. 1 to 4. In the embodiment of the present application, two connecting plates 220 are provided, and the two connecting plates 220 may be arranged symmetrically about the rotation axis of the mounting top plate 200. Based on this structural design, firstly, it is advantageous to simplify the mounting top plate 200 when the connection is satisfied, and secondly, the relative arrangement of the two connecting plates 220 is also helpful to balance the bearing of the mounting top plate 200.

[0039] Further, in the embodiment of the present application, two pairs of fixing block 120 are provided, and each pair of the fixing blocks 120 is arranged symmetrically around the rotation axis of the mounting top plate 200. In this embodiment, the downlight body 100 may be matched with one pair of the fixing blocks, which is beneficial to improve the connection efficiency.

[0040] Please refer to FIGS. 1 to 4. In the embodiment of the present application, the base plate 210 is a plate structure arranged in a tile. In this way, with the plate structure in which the mounting top plate is installed, it is helpful to avoid the occupation of the space of the mounting top plate in the up and down direction.

[0041] Please refer to FIGS. 1 to 4. In the embodiment of the present application, the cylindrical body 110 and each fixing block 120 have an integrated structure. Such that it is advantageous to improve the connection strength between the cylindrical body 110 and each fixing block 120.

[0042] Please refer to FIG. 3. In the embodiment of the present application, the surface-mount downlight also includes a reflective cover 140 located in the cylindrical body 110 and used to focus the light generated by the light source module 130, so as to improve the illumination efficiency.

[0043] Another embodiment of the present application also provides a surface-mount downlight. In this embodiment, according to the definition of the XYZ rectangular coordinate system established in FIG. 5, the positive direction of the X axis is defined as the front direction, and the negative direction of the X axis is defined as the rear direction. The positive direction of the Y axis is defined as the left direction, and the negative direction of the Y axis is defined as the right direction. The positive direction of the Z axis is defined as the up direction, and The negative direction of the Z axis is defined as the down direction.

[0044] Please refer to FIGS. 5 to 9, the surface-mount downlight includes a mounting top plate 400 and a downlight body 300.

[0045] The mounting top plate 400 is fixed connected to the ceiling. The mounting top plate 400 is arranged flatly so that it is advantageous to avoid the occupation of the space of the mounting top plate 400 in the up and down direction. at least two mounting chute 410 passing through in the up and down direction is formed in the mounting top plate 400, arranged at intervals in the left and right direction, and each mounting chute is extended in the front and rear direction, and both include a front chute section 4101 and a rear chute section 4102 in the front and rear direction, where the groove width of the front chute section 4101 is smaller than the groove width of the rear chute section 410. In this embodiment, the mounting top plate 400 may be made of stainless steel.

[0046] The downlight body 300 includes a shell body 310 having a cylindrical shape, at least two fixed sliding posts 320, and a light source module 330 for generating light located within the shell body 310. The distribution and arrangement of each fixed sliding post 320 corresponds to that of the mounting chute 410, and each fixed sliding post 320 includes a connecting post 321 extended in the up and down direction and a suspension post 322 . The lower end of the connecting post 321 is connected to the shell body 310, while the upper end is connected to the suspension post 322, where the diameter of the connecting post 321 is smaller than the groove width of the front chute section 4101, and the diameter of the suspension post 322 is smaller than the groove width of the rear chute section 4102, so that the suspension post 322 can pass through the rear chute section 4102. The diameter of the suspension post 322 is greater than the groove width of the front chute section 4101, so that the suspension post 322 is suspended by the mounting top plate 400 when being above the front chute section 4101.

[0047] During installation, first installing the mounting top plate 400 to the ceiling, where the installation of the mounting top plate 400 is relatively simple due to the the mounting top plate 400 is lighter in weight, and then lifting the downlight body 300 with each of the suspension posts 322 corresponds to a rear chute section 4102, then making the suspension post 322 pass through the rear chute section 4102, and finally, sliding the connecting post 321 into the front chute section 4102, then removing the external force of lifting the downlight body 300, thereby the suspension post322 is suspended by the mounting top plate 400, and the installation of the surface-mount downlight is completed.

[0048] It can be seen from the above that based on the structural design of the present application, the surface-mount downlight is divided into two parts, one part is the lighter mounting top plate 400, and the other is the heavier downlight body 300. During the installation process, when installing the mounting top plate 400, there is no need to lift the heavier downlight body 300, and when installing the downlight body 300, it only requires lifting the downlight body 300, make each suspension post 322 corresponds to a rear chute section 4102 and make the suspension post 322 passes through the rear chute section 4102, then sliding the connecting post 321 into the front chute section 4101 to complete the installation of the surface-mount downlight, such that the supporting time by the staff is reduced .thereby beneficially reduces the difficulty of installation by the staff.

[0049] In the embodiment of the present application, the downlight body 300 has a rectangular structure as a whole.

[0050] Please refer to FIGS. 6 and 9. In the embodiment of the present application, the downlight body 300 may also include an intermediate connecting member 340 for connecting each fixed sliding post 320 to the shell body 310. The intermediate connecting member 340 is located within the shell body 310. Based on this structure, firstly, it is advantageous to simplify the thickness of the shell body 310, and secondly, the fixed sliding post 320 can be hidden inside the shell body 310.

[0051] Referring to FIG. 7, in the embodiment of the present application, at least two first screw holes are formed on the upper side of the intermediate connecting member 340, each connecting post 321 is provided with an external thread on the outer cylindrical surface, and each connecting post 321 is threadingly engaged in the first screw hole. Based on this structural design, it is advantageous to adjust the positional relationship between the mounting top plate 400 and the downlight body 300 through the rotation of each connecting post 321. In actual applications, the mounting top plate 400 may be inclined, then the connecting post can be rotated 321 to adjust without remounting the mounting top plate 400 again.

[0052] Referring to FIG. 7. In the embodiment of the present application, the intermediate connecting member 340 has an annular structure, and the outer annular surface of the intermediate connecting member 340 contact against the inner wall of the shell body 310. Based on this structural design, the outer shape of the intermediate connecting member 340 matches the cross-sectional shape of inner wall of the shell body 310, so that it beneficially improves a placement efficiency for placing the intermediate connecting member 340 on the inner wall of the shell body 310.

[0053] Referring to FIG. 7, in the embodiment of the present application, the downlight body 300 may also include at least two connection assemblies 350. The connection assembly 350 includes connection protrusions integrally connected to the shell body 310 and located in a cavity of the shell body 310 and fastening screws for fastening the intermediate connecting member 340 to the connecting protrusions, the connecting protrusion is provided with a second screw hole on its upper side, and each connecting protrusion is located on the lower side of the intermediate connecting member 340; the intermediate connecting member 340 is provided with at least two through-holes, each of which is used for the fastening screw to pass through and screwed to the second screw hole. Based on this structural design, it is advantageous to simplify the connection relationship between the shell body 310 and the intermediate connecting member 340.

[0054] Please refer to FIGS. 5 and 7, in the embodiment of the present application, the projection of the mounting top plate 400 in the up and down direction falls into that of the shell body 310 in the up and down direction. Such that the shell body 310 may be able to cover the mounting top plate 400 and prevent the mounting top plate 400 from being exposed in the up and down direction.

[0055] Further, the horizontal position of the intermediate connecting member 340 is lower than that of the upper opening of the shell body 310. Such that the mounting top plate 400 can be accommodated in the shell body 310 and further prevented from being exposed.

[0056] Please refer to FIGS. 5 and 7. In the embodiment of the present application, the surface-mount downlight further includes an elastic arm 500. One end of the elastic arm 500 is connected to the mounting top plate 400 and the other end extends downward. The elastic arm 500 elastically interferes with the intermediate connecting member 340 when the suspension post 322passes through the rear chute section 4102 and the connecting post 321 moves to the front chute section 4101, so that it beneficially increases the static friction force between the mounting top plate 400 and the suspension post 322 due to the elastic restoring force of the elastic arm 500 after the downlight body 300 is connected to the mounting top plate 400, thereby beneficially prevents the downlight body 300 from sliding out of the mounting top plate 400.

[0057] Referring to FIG. 6, in the embodiment of the present application, the length of the front chute section 4101 is greater than the diameter of the connecting post 321, which is beneficial to avoid the connecting post 321 automatically sliding out of the front chute section 4101, and the length of the front chute section 4101 It is larger than the diameter of the suspension post 322 so that it is beneficial to ensure that the contact area of the suspension post 322 and the intermediate connecting member 340 is maximized.

[0058] Referring to FIG. 7, in the embodiment of the present application, the surface-mount downlight further includes a reflective cover 360 located in the shell body 310 and used to focus the light generated by the light source module 330.

[0059] The above disclosures are merely the preferred embodiments of the present application, and are not intended to limit this application. Any modification, equivalent replacement or improvement made under the spirit and principles of this application should be included by the protection scope of the present application.
