Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a lamp holder structure and a lamp. Background Art

[0002] Most of the existing ceiling recessed lights have fixed lamp bodies. In actual applications, the angle of the lamp needs to be adjusted to meet different scene requirements. When the lamp body is adjusted to a certain angle, there will be an obvious gap between the rotated lamp body and the mounting panel, causing light leakage, which destroys the overall sense and aesthetics of the ceiling recessed light. Summary of the invention

[0003] In view of this, the present invention provides a lamp holder structure and a lamp to solve the problem of light leakage caused by an obvious cavity between the lamp body and the mounting panel after the lamp body of the existing top ceiling recessed lamp is rotated.

[0004] In a first aspect, the present invention provides a lamp holder structure, comprising a positioning assembly and a cover. The positioning assembly has a mounting groove. The cover is suitable for positioning a lamp body and wrapping the lamp body, at least a portion of the cover is inserted into the mounting groove, the side of the cover is rotatably connected to the side of the positioning assembly, and the rotation centerline of the cover is not colinear with the central axis of the cover, so that the cover can rotate and swing relative to the positioning assembly.

[0005] When the cover rotates relative to the positioning assembly, at least part of the cover is always contained in the mounting groove, so that the cover can fully cover the lamp body. Even if the cover rotates, it can still cover the lamp body, so that light leakage will not occur due to rotation.

[0006] The above-mentioned lamp holder structure utilizes the side of the cover body to be rotated and arranged on the positioning assembly, so that the lamp body can be adjusted in angle, and the lamp body can be fully covered when the angle is adjusted. After the cover body and the lamp body are rotated, there will be no holes between the cover body and the positioning assembly, thereby avoiding the problem of light leakage. Moreover, when the lamp body and the cover body rotate synchronously, the relative positions between the two are changed, and the light-emitting surface of the lamp body will not be blocked by the cover body after the lamp body rotates, ensuring that the lamp body can emit light normally after the lamp body rotates.

[0007] In an optional embodiment, the positioning component includes:

[0008] Mounting ring;

[0009] A snap ring is positioned at the inner ring position of the mounting ring, and the mounting groove is formed between the outer side wall of the snap ring and the inner side wall of the mounting ring.

[0010] In an optional embodiment, the side of the cover body is rotatably connected to the side of the positioning assembly via one or two rotating shafts.

[0011] In an optional embodiment, a first positioning hole is formed on the side wall of the mounting ring, a second positioning hole is formed on the side wall of the snap ring, a third positioning hole is formed on the side wall of the cover body, a rotating shaft is fixedly disposed in the third positioning hole, and the rotating shaft is rotatably disposed in the first positioning hole and the second positioning hole;

[0012] or

[0013] The side wall of the mounting ring is provided with two first positioning holes which are symmetrically arranged about the central axis of the mounting ring, the side wall of the retaining ring is provided with two second positioning holes which are symmetrically arranged about the central axis of the retaining ring, and the side wall of the cover body is provided with two third positioning holes which are symmetrically arranged about the central axis of the cover body, and a rotating shaft is fixedly arranged in each of the two third positioning holes, and the rotating shaft is rotatably arranged in the first positioning hole and the second positioning hole.

[0016] A positioning part is provided with a through hole suitable for the lamp body to pass through, and the positioning part is positioned with the lamp body.

[0017] The cover body uses the positioning part to position the lamp body, and the inner cavity of the rotating part is connected with the through hole, so that the lamp body passes through the through hole and enters the inner cavity of the positioning part and is wrapped by the positioning part.

[0018] In an optional embodiment, the mounting ring and the retaining ring are both configured to be annular, the mounting groove is a circular groove, and the rotating portion is configured to be spherical.

[0019] The lamp holder structure adopts the method of hemispherical surface moving relative to torus surface, so that the cover body and the mounting ring are closely connected without gaps, and the integrity of the lamp body appearance is always guaranteed within the rotation range, without voids and light leakage.

[0020] In an optional embodiment, one side edge of the cover body abuts against the mounting groove, and there is a spacing between the other side edge of the cover body and the mounting groove, so that when the cover body rotates relative to the positioning assembly, the side of the cover body abutting against the mounting groove rotates toward the side of the cover body with the spacing between the cover body and the mounting groove, so that the cover body can rotate normally.

[0021] In an optional embodiment, at least one mounting plate is provided on the outer side wall of the positioning assembly, and the mounting plate is suitable for being positioned on the ceiling.

[0022] In a second aspect, the present invention further provides a lamp, comprising:

[0023] The lamp holder structure;

[0024] The lamp body is telescopically arranged on the lamp holder structure.

[0025] When the lamp body needs to be rotated at a large angle, the lamp body can be easily stretched outward to expose the lamp head of the lamp body, and then the lamp body and the cover body are rotated, so that the light-emitting surface of the lamp body after rotation will not face the cover body and the clamp ring, and the light-emitting surface of the lamp body can be exposed from the position of the clamp ring. While realizing the large-angle rotation of the lamp body, the light-emitting surface of the lamp body after rotation will not be blocked, avoiding waste of light. Different from the rotation method of traditional lamps, the rotation structure of the present invention adopts spherical relative motion, which always ensures the integrity of the appearance of the lamp body within the rotation range, without voids and light leakage.

[0033] The housing is provided with a wire-passing post, which passes between two adjacent first heat dissipation fins and is suitable for accommodating a connection terminal electrically connected to the light-emitting component.

[0034] In an optional embodiment, a connecting plate is provided between two adjacent first heat dissipating fins, and a plurality of second heat dissipating fins are arranged at intervals on the connecting plate. The arranged second heat dissipating fins can increase the contact area with the external atmosphere, thereby improving the heat dissipation effect.

[0035] In an optional embodiment, the housing includes a lower housing and an upper housing that are detachably connected; the light-emitting component is detachably disposed in a cavity formed between the lower housing and the upper housing. When the light-emitting component needs to be replaced, the housing can be opened to quickly replace the light-emitting component with a suitable specification and model, and the housing and the lamp holder structure do not need to be replaced, which can achieve centralized stocking in various markets without repeated inventory, and can quickly meet various personalized needs of customers, reduce product inventory, and reduce the business risk of the enterprise.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0049] Ceiling lights are a type of lighting and modern decorative lamps that provide good lighting effects and decorative functions. The design of ceiling lights allows them to be embedded in the ceiling and illuminate with downward light, without destroying the perfect unity of the ceiling art due to the setting of the lamp. Most of the existing ceiling recessed lights have fixed lamp bodies. In actual applications, the angle of the lamp needs to be adjusted to meet different scene requirements. When the lamp body is adjusted to a certain angle, there will be an obvious gap between the rotated lamp body and the installation panel, causing light leakage, which destroys the overall sense and aesthetics of the ceiling recessed lamp.

[0050] Based on this, the present invention provides a lamp holder structure, which utilizes the method of rotating the cover body on the positioning assembly to meet the angle adjustment of the lamp body while enabling the cover body to rotate synchronously when the lamp body rotates, thereby avoiding the problem of light leakage.

[0051] In addition, the light-emitting surface of the rotated lamp body may be blocked by the lamp decorative cover, resulting in a waste of light.

[0052] Based on this, the present invention provides a lamp, in which the lamp body is telescopically arranged on the lamp holder structure. When the lamp body needs to be rotated at a large angle, the lamp body can be conveniently stretched outward, and then the lamp body and the cover body are rotated to achieve a large angle rotation of the lamp body. After the rotation, the light-emitting surface of the lamp body will not be blocked, thereby avoiding waste of light.

[0053] In addition, in order to quickly meet customers' requirements for different color temperatures, CRIs, and light effects, a large number of lamps with the same specifications and different light sources need to be stocked. Due to market uncertainty, a large number of lamp stocks will be created, and after a period of time, the long-stocked products will be scrapped due to the rapid upgrade of light sources.

[0054] Based on this, the present invention provides a lamp, in which the light-emitting component is detachably arranged inside a shell. When the light-emitting component needs to be replaced, the shell can be opened to quickly replace the light-emitting component. The light-emitting component can be replaced with a suitable specification and model, and the shell and the lamp holder structure do not need to be replaced, thereby reducing product inventory.

[0055] Combine the following Figures 1 to 9 , the lamp holder structure of the first aspect of the present invention and the lamp of the second aspect of the present invention are elaborated in detail.

[0056] According to an embodiment of the present invention, in a first aspect, a lamp holder structure is provided, Figure 1 As shown, it includes a positioning assembly 1 and a cover 2. The positioning assembly 1 has a mounting groove 103. The cover 2 is suitable for positioning the lamp body 3 and wrapping the lamp body 3. At least part of the cover 2 is inserted into the mounting groove 103. The side of the cover 2 is rotatably connected with the side of the positioning assembly 1. The rotation center line of the cover 2 is not colinear with the central axis of the cover 2, so that the cover 2 can rotate and swing relative to the positioning assembly 1. It should be noted that the rotation centerline of the cover body 2 is the centerline of the cover body when it rotates relative to the positioning assembly 1; the central axis of the cover body 2 is the geometric central axis of the cover body, and in this embodiment, the direction of the central axis of the cover body 2 is the vertical direction; the rotation centerline of the cover body 2 is not colinear with the central axis of the cover body 2, that is, the rotation centerline of the cover body 2 and the central axis of the cover body 2 can intersect vertically, the rotation centerline of the cover body 2 and the central axis of the cover body 2 can also intersect obliquely, and the rotation centerline of the cover body 2 and the central axis of the cover body 2 can also be neither intersecting nor parallel, and thus when the cover body 2 rotates, it does not rotate around the central axis of the cover body 2, but swings around the rotation centerline of the cover body 2 relative to the positioning assembly 1.

[0057] When the cover body 2 rotates relative to the positioning assembly 1, at least a portion of the cover body 2 is always contained in the mounting groove 103, so that the cover body 2 can fully cover the lamp body 3. Even if the cover body 2 rotates, it can still cover the lamp body 3 so that light leakage will not occur due to the rotation.

[0058] The above-mentioned lamp holder structure utilizes the side of the cover body 2 to be rotated and set on the positioning assembly 1, so that the lamp body 3 can be adjusted in angle, and the lamp body 3 can be fully covered when the angle is adjusted. After the cover body 2 and the lamp body 3 are rotated, there will be no holes between the cover body 2 and the positioning assembly 1, thereby avoiding the problem of light leakage. Moreover, when the lamp body 3 and the cover body 2 rotate synchronously, the relative positions between the two are changed differently, and thus the light-emitting surface of the lamp body 3 will not be blocked by the cover body 2 after the lamp body 3 rotates, ensuring that the lamp body 3 can emit light normally after the lamp body 3 rotates.

[0059] In one embodiment, in combination Figure 2 and Figure 3 As shown, the positioning assembly 1 includes a mounting ring 101 and a clamping ring 102. The mounting ring 101 is embedded and mounted on the ceiling. A first annular plate 1012 is provided at the bottom end of the side wall of the mounting ring 101. When the mounting ring 101 is positioned on the ceiling, the first annular plate 1012 is flush with the bottom wall of the ceiling, thereby ensuring the integrity and aesthetics of the installation.

[0060] The snap ring 102 is positioned at the inner ring position of the mounting ring 101. More specifically, the snap ring 102 is embedded in the bottom of the mounting ring 101. A second annular plate 1013 is provided at the bottom end of the inner side wall of the mounting ring 101, and a certain distance is provided between the second annular plate 1013 and the bottom wall of the mounting ring 101. A snap ring bottom plate 1022 is provided at the bottom end of the outer side wall of the snap ring 102. When installing the snap ring 102, the snap ring 102 is installed into the mounting ring 101 from bottom to top, and the snap ring bottom plate 1022 is abutted against the bottom wall of the second annular plate 1013, and the snap ring 102 is embedded in the mounting ring 101.

[0061] An installation groove 103 is formed between the outer wall of the snap ring 102 and the inner wall of the installation ring 101 . The specifications of the installation groove 103 can be adjusted by adjusting the specifications of the snap ring 102 and the installation ring 101 .

[0062] In one embodiment, the side of the cover body 2 is rotatably connected to the side of the positioning assembly 1 via a rotating shaft 5. A first positioning hole 1011 is formed on the side wall of the mounting ring 101, a second positioning hole 1021 is formed on the side wall of the clamping ring 102, and a third positioning hole 2011 is formed on the side wall of the cover body 2. The rotating shaft 5 is fixedly disposed in the third positioning hole 2011, and the rotating shaft 5 is rotatably disposed in the first positioning hole 1011 and the second positioning hole 1021. In this embodiment, the cover body 2 can be rotated with the rotating shaft 5 as the rotation center line, thereby realizing the angle adjustment of the lamp body 3.

[0063] As a replaceable embodiment, the side of the cover body 2 is rotatably connected to the side of the positioning assembly 1 through two rotating shafts 5. Two first positioning holes 1011 symmetrically arranged about the central axis of the mounting ring are provided on the side wall of the mounting ring 101, two second positioning holes 1021 symmetrically arranged about the central axis of the snap ring are provided on the side wall of the snap ring 102, and two third positioning holes 2011 symmetrically arranged about the central axis of the cover body are provided on the side wall of the cover body 2. A rotating shaft 5 is fixedly arranged in each of the two third positioning holes 2011, and the rotating shaft 5 is rotatably arranged in the first positioning hole 1011 and the second positioning hole 1021. In this embodiment, the two rotating shafts 5 are arranged relative to each other so that the rotation center line of the cover body 2 is colinear with the central axis of the two rotating shafts 5, and the two rotating shafts 5 can ensure the stability of the rotation of the cover body 2.

[0064] In one embodiment, the cover body 2 includes a rotating portion 201 and a positioning portion 202. At least part of the rotating portion 201 is inserted into the mounting groove 103 and is rotatably connected to the positioning assembly 1. The positioning portion 202 is provided with a through hole 2022 suitable for the lamp body 3 to pass through, and the positioning portion 202 is positioned with the lamp body 3. In this embodiment, the positioning portion 202 is used to position the lamp body 3, and the inner cavity of the rotating portion 201 is connected with the through hole 2022, so that the lamp body 3 passes through the through hole 2022 and enters the inner cavity of the positioning portion 202 and is wrapped by the positioning portion 202.

[0065] In one embodiment, the mounting ring 101 and the clamping ring 102 are both set to be annular, the mounting groove 103 is an annular groove, and the rotating part 201 is set to be spherical. In this embodiment, the semi-spherical surface moves relative to the annular surface, so that the cover body 2 and the mounting ring 101 are closely connected without gaps, and the integrity of the appearance of the lamp body is always guaranteed within the rotation range, without holes, and no light leakage.

[0066] In order to ensure that the cover body 2 can rotate normally, in one embodiment, a notch is provided on the cover body 2, so that one side edge of the cover body 2 abuts against the mounting groove 103, and there is a gap between the other side edge of the cover body 2 and the bottom wall of the mounting groove 103, so that when the cover body 2 rotates relative to the positioning assembly 1, the side of the cover body 2 abutting against the mounting groove 103 rotates toward the side of the cover body 2 with the gap between the mounting groove 103. In this embodiment, the cover body 2 can be rotated toward the position of the notch, and because one side edge of the cover body 2 abuts against the mounting groove 103 in a normal state, it can be ensured that the cover body 2 is in a stable state when not rotating.

[0067] In one embodiment, at least one mounting plate 104 is disposed on the outer side wall of the positioning assembly 1, and the mounting plate 104 is suitable for being positioned on the ceiling. More specifically, the outer side wall position of the mounting ring 101 connected to the mounting plate 104 is set to be a rectangular plate, which facilitates the connection between the mounting ring 101 and the mounting plate 104. A plurality of buckles are disposed on the mounting plate 104, which facilitates the mounting plate 104 to be embedded and installed on the ceiling.

[0068] According to an embodiment of the present invention, in a second aspect, a lamp is further provided, comprising a lamp holder structure and a lamp body 3. The lamp body 3 is telescopically arranged on the lamp holder structure. Figures 7 to 9 As shown, when the lamp body 3 needs to be rotated at a large angle, the lamp body 3 can be conveniently stretched outward (if the lamp is installed in a manner that the light-emitting surface of the lamp body 3 faces downward, the lamp body 3 is stretched downward) to expose the lamp head 3031 of the lamp body 3, and then the lamp body 3 and the cover 2 are rotated, so that the light-emitting surface of the lamp body 3 after rotation will not face the cover 2 and the clamp 102, and the light-emitting surface of the lamp body 3 can be exposed from the position of the clamp 102. While realizing the large-angle rotation of the lamp body 3, the light-emitting surface of the lamp body 3 after rotation will not be blocked, avoiding waste of light. Different from the rotation method of traditional lamps, the rotation structure of the present invention adopts spherical relative motion, which always ensures the integrity of the appearance of the lamp body within the rotation range, without voids and light leakage.

[0069] In one embodiment, the lamp body 3 includes a shell and a light-emitting component 303. The light-emitting component 303 is positioned inside the shell. The shell includes a lower shell 301 and an upper shell 302 that are detachably connected. The light-emitting component 303 is detachably arranged in a cavity formed between the lower shell 301 and the upper shell 302. When the light-emitting component needs to be replaced, the shell can be opened to quickly replace the light-emitting component, and the light-emitting component can be replaced with a suitable specification model. The shell and the lamp holder structure do not need to be replaced, which can realize centralized stocking in various markets without repeated inventory, and can quickly meet various personalized needs of customers, reduce product inventory, and reduce the business risk of the enterprise.

[0070] As a specific embodiment, Figure 5 As shown, the light emitting assembly 303 includes a lamp holder 3031, an LED chip 3032, a PCB board 3033 and a cover board 3036. A positioning hole is provided at the center of the lower housing 301, and the lamp holder 3031 is embedded in the positioning hole. The lamp holder 3031 is provided directly below the LED chip 3032 to diffuse the light emitted by the LED chip 3032. The LED chip 3032 is electrically connected to a conductive spring 3034, and the conductive spring 3034 is electrically connected to the PCB board 3033. The conductive spring 3034 is provided below the PCB board 3033.

[0071] A partition 3023 is provided on the upper shell 302, and a conductive layer is provided at the bottom of the partition 3023. The conductive layer includes two conductive circles 3037. Two spring pins 3035 are provided on the PCB board 3033. The two conductive circles 3037 correspond to one spring pin 3035 respectively. The spring pin 3035 can pass through the cover plate 3036 and abut against the conductive circle 3037.

[0072] After the upper shell 302 and the lower shell 301 are connected, the LED chip 3032 is electrically connected to the PCB board 3033 through the conductive spring 3034, and the PCB board 3033 is electrically connected to the conductive ring 3037 through the spring pin 3035, thereby realizing the electrical connection between the LED chip 3032 and the conductive ring 3037. Therefore, in this embodiment, it is not necessary to weld and fix the PCB board 3033 and the LED chip 3032. When the PCB board 3033 and the LED chip 3032 are installed, it is only necessary to install the LED chip 3032 on the cover plate 3036, and then overlap the cover plate 3036 with the LED chip 3032 and the PCB board 3033 to realize the power supply of the LED chip 3032; when the LED chip 3032 is disassembled, after the shell is opened, the LED chip 3032 overlapped on the PCB board 3033 can be directly removed, so that the LED chip 3032 can be easily replaced.

[0073] Combination Figure 4 As shown, the bottom side wall of the upper shell 302 is threadedly connected to the top side wall of the lower shell 301. When the upper shell 302 is screwed onto the lower shell 301, the PCB board 3033 is pressed against the conductive spring sheet 3034, so that the PCB board 3033 can be electrically connected to the spring pin 3035 on the conductive spring sheet 3034. The LED chip 3032 (COB chip) in this embodiment is easy to install, and the electrical connection is completed through simple assembly fixation and conductive overlap. When the light-emitting component 303 is replaced, the upper shell 302 can be opened, and one or more of the lamp holder 3031, the LED chip 3032 and the PCB board 3033 can be manually removed and directly replaced without using tools, which is very convenient.

[0074] In one embodiment, a heat dissipation structure 4 is also positioned on the shell, and the heat dissipation structure 4 is arranged above the upper shell 302. The heat dissipation structure 4 is used to dissipate the heat emitted by the light-emitting component 303 in time to avoid heat accumulation at the position of the light-emitting component 303, thereby avoiding malfunction due to excessive temperature of the light-emitting component 303.

[0075] At least one sliding bar 3022 is provided on the shell, and at least one strip groove 401 is provided on the heat dissipation structure 4. The sliding bar 3022 is assembled in the strip groove 401, thereby realizing the connection and positioning between the shell and the heat dissipation structure 4, so that the two can be raised and lowered synchronously.

[0076] The sliding bar 3022 is a metal bar, and a positioning block 2021 is provided on the inner side wall of the cover body 2. The positioning block 2021 is slidably fitted with the sliding bar 3022 and magnetically attached to the sliding bar 3022, so that the housing and the heat dissipation structure 4 can perform telescopic movements along the positioning block 2021 of the cover body 2. During the telescopic process of the lamp body 3 on the housing, the lamp body 3 telescopes along the central axis of the cover body 2, ensuring that there is no gap between the cover body 2 and the lamp body 3, and ensuring that there is no light leakage during the telescopic process. In addition, the damping force of the housing and the heat dissipation structure 4 during the sliding process is relatively stable, and no effort is required to adjust no matter where they slide to.

[0077] Combination Figure 6 As shown, the heat dissipation structure 4 includes a central column 403 and a plurality of first heat dissipation fins 402, and each first heat dissipation fin 402 is arranged at intervals on the periphery of the central column 403. A wire-passing column 3021 is provided on the housing, and the wire-passing column 3021 passes between two adjacent first heat dissipation fins 402, and the wire-passing column 3021 is suitable for accommodating a terminal electrically connected to the light-emitting component 303. In this embodiment, the heat emitted by the light-emitting component 303 can be transferred to the outside atmosphere through each of the first heat dissipation fins 402, thereby achieving the purpose of heat dissipation.

[0078] A connecting plate 404 is disposed between two adjacent first heat dissipation fins 402 , and a plurality of second heat dissipation fins 405 are disposed at intervals on the connecting plate 404 . The disposed second heat dissipation fins 405 can increase the contact area with the external atmosphere, thereby improving the heat dissipation effect.
