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.

[0061] Ceiling lamp is a kind of lighting and modern decorative lamp, which provides good lighting effect and decorative function. The design of ceiling lamp enables it to be embedded in the ceiling, and the light is emitted downward, which will not destroy the perfect unity of the ceiling art due to the setting of the lamp.

[0062] The light source in the lighting product can be configured according to the actual use requirements. The COB in the existing light source is usually connected to the circuit board by welding. In order to quickly meet customers' requirements for different color temperatures, CRIs, light effects, etc. of the lamps, it is often necessary to produce a large number of lamps with the same specifications and different light sources. Due to market uncertainty, a large amount of lamp inventory will be created. After a period of time, the rapid upgrade of the light source will cause the long-term inventory of products to be scrapped, resulting in waste.

[0063] Based on this, the present invention provides a lamp body, in which the light-emitting component is detachably arranged inside the 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.

[0064] The COB in the existing light source is usually connected to the PCB board by welding, which makes it inconvenient to remove the COB from the PCB board and to replace the COB on the lamp.

[0065] Based on this, the present invention provides a lamp body, after the upper shell and the lower shell are connected, the LED chip and the PCB board are electrically connected through the conductive spring sheet, and the PCB board is electrically connected to the second conductive part through the spring pin, thereby realizing the electrical connection between the LED chip and the second conductive part. Therefore, the present invention does not need to weld and fix the PCB board and the LED chip.

[0066] Combine the following Figures 1 to 14 , the lamp body of the first aspect of the present invention and the lamp of the second aspect of the present invention are described in detail.

[0067] According to an embodiment of the present invention, in a first aspect, a lamp body is provided, Figures 1 to 7As shown, it includes a housing and a light-emitting component 303, and the light-emitting component 303 is positioned inside the housing. The housing includes a lower housing 301 and an upper housing 302 that are detachably connected, and a cavity is formed between the lower housing 301 and the upper housing 302. The light-emitting component 303 is detachably arranged in the cavity, and the light-emitting component 303 has a light-emitting portion and a first conductive portion.

[0068] The light-emitting part of the light-emitting component 303 is exposed from the lower housing 301, and a second conductive part is provided on the surface of the upper housing 302 opposite to the light-emitting component 303, the second conductive part corresponds to the first conductive part, and a connection terminal 306 is provided on the second conductive part, the connection terminal 306 can be extended from the upper housing 302, and the second conductive part is electrically connected to the wire provided outside the upper housing 302 through the connection terminal 306. As an alternative embodiment, the light-emitting part of the light-emitting component 303 is exposed from the upper housing 302, and a second conductive part is provided on the surface of the lower housing 301 opposite to the light-emitting component 303, the second conductive part corresponds to the first conductive part, and a connection terminal 306 is provided on the second conductive part, the connection terminal 306 can be extended from the lower housing 301, and the second conductive part is electrically connected to the wire provided outside the lower housing 301 through the connection terminal 306.

[0069] After the upper shell 302 and the lower shell 301 are connected, the first conductive part is electrically connected to the second conductive part. After the upper shell 302 and the lower shell 301 are separated, the first conductive part is disconnected from the second conductive part.

[0070] In the above-mentioned lamp body, since the light-emitting component 303 can directly obtain electricity through the second conductive part arranged on the shell, the light-emitting component 303 can be modularly arranged, and the light-emitting component 303 and the shell do not need to be fixed. After the light-emitting component 303 is installed in the cavity of the shell and the upper shell 302 and the lower shell 301 are assembled, the light-emitting component 303 can be electrically connected to the connection terminal on the shell, and the light-emitting component 303 can be quickly replaced.

[0071] When the light emitting component 303 needs to be replaced, the shell can be opened to quickly replace the light emitting component 303. The light emitting component 303 can be replaced with a suitable specification and model without the need to replace the shell and the lamp holder structure. Centralized stocking can be achieved in various markets without repeated inventory. Various personalized needs of customers can be quickly met, product inventory can be reduced, and the operating risks of the enterprise can be reduced.

[0072] Furthermore, the lamp body can be installed in a modular manner. After the lower shell 301 and the upper shell 302 are installed and fastened, the lamp body can be installed, which is very convenient.

[0073] The following takes an example in which the light-emitting part of the light-emitting component 303 is exposed from the lower shell 301, a second conductive part is provided on the opposite surface of the upper shell 302 and the light-emitting component 303, the second conductive part corresponds to the first conductive part, and the second conductive part is electrically connected to the connection terminal provided outside the upper shell 302, to explain the specific structure of the lamp body.

[0074] A first through hole is disposed in the middle of the lower housing 301 , and a light emitting component mounting groove 3031 is disposed at the top of the lower housing 301 . The light emitting component mounting groove 3031 is located outside the first through hole. The second conductive part is disposed at the bottom of the upper housing 302 .

[0075] In some embodiments, in combination Figure 2 , Figure 3 As shown, the light-emitting component 303 includes an LED chip 3032, a PCB board 3033, a cover plate 3036, a conductive spring 3034 and a spring pin 3035. The PCB board 3033 is arranged in the light-emitting component installation groove 3031, and a second through hole is arranged in the middle of the PCB board 3033, and the second through hole is arranged corresponding to the first through hole. An LED chip positioning hole is arranged in the middle of the cover plate 3036. The LED chip 3032 is a light-emitting part, and the LED chip 3032 is installed in the LED chip positioning hole. The cover plate 3036 fixes the LED chip 3032 by shape matching to form a corner fixation. The LED chip 3032 is electrically connected to the PCB board via the conductive spring 3034, and the LED chip 3032 is arranged opposite to the second through hole and the first through hole, which is conducive to the heat dissipation through these through holes, thereby improving the heat dissipation performance of the LED chip 3032. The number of conductive springs 3034 is determined by the circuits on the PCB board, and two are usually provided. The conductive springs 3034 are electrically connected to the PCB board 3033, and the conductive springs 3034 are provided below the PCB board 3033. Two spring pins 3035 are provided, and the two spring pins 3035 are the first conductive parts. One end of the two spring pins 3035 is electrically connected to the PCB board 3033, and the other end of the two spring pins 3035 can pass through the cover plate 3036 and abut against the second conductive part.

[0076] In this embodiment, the PCB board 3033, the cover plate 3036 and the LED chip 3032 are separately arranged. After the upper shell 302 and the lower shell 301 are connected, the LED chip 3032 and the PCB board 3033 are electrically connected through the conductive spring sheet 3034, and the PCB board 3033 is electrically connected to the second conductive part through the spring pin 3035, thereby realizing the electrical connection between the LED chip 3032 and the second conductive part. Therefore, in this embodiment, there is no need to weld and fix the PCB board 3033 and the LED chip 3032. When installing the PCB board 3033 and the LED chip 3032, 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 opening the shell, the LED chip 3032 stacked on the PCB board 3033 can be directly removed, which is convenient for replacing the LED chip 3032.

[0077] This embodiment integrates components such as the LED chip 3032, the PCB board 3033, the conductive spring 3034 and the spring pin 3035 to achieve a compact design, reduce the volume of the entire light-emitting component 303, and make it more suitable for application scenarios with limited space.

[0078] After the lower shell 301 and the upper shell 302 are fastened, electricity can be taken through the spring pin 3035 (PIN pin), ensuring a stable electrical connection between the PCB board 3033 and the external power supply. The spring pin connection method allows the LED chip to be easily disassembled and reinstalled when necessary. In addition, the spring pin 3035 passes through the PCB board 3033 and the cover plate 3036. The two spring pins 3035 can prevent the PCB board 3033 from moving or loosening in the shell, thereby improving the stability of the overall structure. In addition, when installing the light-emitting component 303, it is only necessary to pass the spring pin 3035 through the PCB board 3033 and the cover plate 3036 and abut against the second conductive part. When maintenance or replacement of parts is required, it is also easier to disassemble and reinstall.

Preferably, the two conductive circles are concentrically arranged. In this embodiment, one end of an elastic pin 3035 is connected to a pole of the PCB board 3033, and the other end of the elastic pin 3035 abuts one of the conductive circles; one end of another elastic pin 3035 is connected to another pole of the PCB board 3033, and the other end of the elastic pin 3035 abuts another conductive circle therein, thereby forming a conductive loop. The above-mentioned conductive circles are electrically connected to the external power supply wire through the wiring terminal.

[0080] In this embodiment, since the conductive layer 305 is detachably disposed at the bottom of the upper housing, when the conductive layer 305 needs to be replaced, it can be conveniently removed and replaced with a new conductive layer 305 without replacing the entire upper housing. The conductive layer 305 is usually made of a material with good thermal conductivity, so that the heat generated by the LED chip can be conducted from the upper housing 302 to the heat dissipation structure, thereby improving the overall heat dissipation performance.

[0081] As a specific embodiment, Figure 6 and Figure 7 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 tightened onto the lower shell 301, the LED chip 3032 is pressed against the conductive spring sheet 3034, so that the LED chip 3032 can be electrically connected to the conductive spring sheet 3034, and the two spring pins 3035 are respectively abutted against the two conductive rings 3051 to achieve electrical connection between the spring pins 3035 and the conductive rings 3051.

More specifically, the clamping portion 30362 is a buckle, so that the assembly process of the cover plate 3036 is very simple and quick. The operator only needs to align the clamping portion with the clamping hole and gently press it to complete the positioning and fixing, without the need for complex tools.

[0089] In some embodiments, in combination Figure 2 and Figure 3 As shown, the conductive spring 3034 includes a conductive spring fixed end and a conductive spring free end which are integrally connected.

[0092] In some embodiments, in combination Figure 2 As shown, an annular protrusion 3016 is provided in the light-emitting component mounting groove 3031, and the annular protrusion 3016 is located outside the first through hole. The annular protrusion 3016 is adapted to the second through hole on the PCB board 3033, ensuring precise alignment between the PCB board and the lower shell, and preventing the PCB board from loosening or shifting due to vibration or other external forces during use.

[0093] In some embodiments, in combination Figure 2 As shown, a conductive spring sheet positioning groove 3017 is disposed in the light emitting component mounting groove 3031 to provide an accommodating space for the conductive spring sheet 3034 .

[0094] In some embodiments, in combination Figure 3 As shown, an LED chip mounting groove 30364 is provided at the bottom end of the cover plate 3036, and the LED chip 3032 is arranged in the LED chip mounting groove 30364. When the LED chip 3032 needs to be removed from the cover plate 3036, the LED chip 3032 can be directly removed from the LED chip mounting groove 30364 after the cover plate 3036 is separated from the lower shell 301.

[0095] In some embodiments, in combination Figure 7 As shown, a lamp holder 304 is detachably connected to the lower shell 301 , and the lamp holder 304 is correspondingly arranged directly below the LED chip 3032 , and the lamp holder 304 can disperse the light emitted by the LED chip 3032 .

[0096] In some embodiments, in combination Figure 8 , Fig.11 As shown, 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 and avoid malfunction due to excessive temperature of the light-emitting component 303.

[0097] 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.

[0098] The sliding bar 3022 is a metal bar, and a positioning block 2021 is provided on the inner wall of the cover body 2. The positioning block 2021 is slidably assembled with the sliding bar 3022 and magnetically adhered to the sliding bar 3022, so that the shell and the heat dissipation structure 4 can be telescoped along the positioning block 2021 of the cover body 2, and the damping force of the shell 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.

[0099] During the extension and retraction process of the lamp body 3 on the housing, the lamp body 3 is extended and retracted along the central axis direction of the cover body 2, ensuring that there is no gap between the cover body 2 and the lamp body 3 at all times, and ensuring that there is no light leakage during the extension and retraction process.

[0100] Combination Figure 8 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.

[0101] 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.

[0102] Combination Figure 5 As shown, the heat dissipation structure 4 further includes a heat-conducting column 406 , in which a heat-conducting hole 4061 is provided. The heat-conducting hole 4061 is connected to the fourth heat dissipation hole 3024 to conduct heat away from the inside of the shell.

[0103] According to an embodiment of the present invention, in a second aspect, a lamp is provided, comprising a lamp holder structure and a lamp body 3. The lamp body 3 is telescopically arranged on the lamp holder structure. Figure 12 to Figure 14As shown, when the lamp body 3 needs to be rotated at a large angle, the lamp body 3 can be easily 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 304 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.

[0104] Combination Fig. 9 As shown, the lamp holder structure 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 to 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.

[0105] 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.

[0106] 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 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, and 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.

[0107] In some embodiments, in combination Fig.10 and Fig.11 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.

[0108] 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.

[0109] 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 .

[0110] In some embodiments, 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 provided on the side wall of the mounting ring 101, a second positioning hole 1021 is provided on the side wall of the clamping ring 102, and a third positioning hole 2011 is provided 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 rotate with the rotating shaft 5 as the rotation center line, thereby realizing the angle adjustment of the lamp body 3.

[0111] 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.

[0112] In some embodiments, 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 to 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.

[0113] In some embodiments, 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.

[0114] In order to ensure that the cover body 2 can rotate normally, in some embodiments, 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.

[0115] In some embodiments, 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.
