Description

Technical Field

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

[0002] Ceiling lights are a kind of high-grade lighting and modern decorative lamps, which are very suitable for shopping malls, supermarkets, hotels, jewelry counters and high-end homes. They are ideal light sources to replace traditional halogen tungsten lamps and metal halide lamps. Ceiling lights are different from spotlights in that they are mainly scattered light sources, with a wide irradiation area, mostly soft light, uniform light spots, and better luminous flux. In addition, ceiling lights are downward-emitting lighting lamps, and the lamps are generally embedded in the ceiling and hidden inside the building decoration. Therefore, the perfect unity of the ceiling art will not be destroyed by setting lamps outside the ceiling, and the overall unity and perfection of the building decoration will be maintained.

[0003] Moreover, with the development of the times, users need to use ceiling lamps in different environments more and more. For example, ceiling lamps are used for daily lighting in the living room and ceiling lamps are used above the display cabinet for exhibits. However, the requirements for lenses or reflectors are different. The lighting effect of daily lighting requires more divergent and uniform light, while the lighting effect of exhibit display requires more concentrated light. Therefore, when the use scene of the ceiling lamp changes, or the required lighting effect changes, the original reflector needs to be replaced with other types of reflectors and lenses with different focusing degrees.

[0004] Obviously, the existing ceiling lamps in the market cannot meet the above-mentioned replacement needs. When the usage scenario of the ceiling lamp changes, or the required lighting effect changes, the ceiling lamp needs to be repaired. Since the existing ceiling lamps are generally an integrated structure or the components are fixed one by one by bolts, the installation and disassembly are troublesome, time-consuming and labor-intensive. Therefore, ordinary users can only purchase new ceiling lamps that meet the new needs, which is a huge waste of users' financial resources and time, and is not conducive to the user's experience.

DETAILED DESCRIPTION

[0056] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0057] like Figure 1-19 As shown, a ceiling lamp includes a lamp holder 100, a heat dissipation base 400, a light-emitting component 500 arranged in the heat dissipation base 400, and a clamping ring 200 supported between the lamp holder 100 and the heat dissipation base 400, wherein the clamping ring 200 and the lamp holder 100 are detachably arranged, the clamping ring 200 and the heat dissipation base 400 are detachably arranged, and further includes a lens 300 detachably arranged in the clamping ring 200.

[0058] The present invention is provided with a lamp stand 100, a heat dissipation base 400, a clamping ring 200, and a lens 300. The clamping ring 200 is provided between the lamp stand 100 and the heat dissipation base 400. When in use, the lamp stand 100 can be detachably connected to the clamping ring 200 by simple operation, and the heat dissipation base 400 can be detachably connected to the clamping ring 200 by simple operation. At the same time, the lens 300 can also be detachably connected to the clamping ring 200 by simple operation. When the usage scene changes, the light output demand changes, or the ceiling lamp needs to be repaired, the lamp stand 100, the heat dissipation base 400, the clamping ring 200, and the lens 300 can be directly disassembled to adjust or repair and replace each component. The installation and disassembly is time-saving and labor-saving, and there is no need to repurchase a complete ceiling lamp, which saves money and is beneficial to the user experience.

[0059] Specifically, as shown in the figure, the retaining ring 200 is an annular structure, and a connecting portion detachably connected to the heat dissipation base 400 is provided on one side of the retaining ring 200 close to the heat dissipation base 400, and a holding portion for detachably fixing the lens 300 is provided on the inner side of the retaining ring 200.

[0060] Specifically, as shown in the figure, the connection part includes a plurality of plug blocks 201 centrally and symmetrically arranged on the side of the clamping ring 200 close to the heat dissipation base 400, and a plurality of slots 401 corresponding to the plug blocks 201 are arranged on the inner wall surface of the heat dissipation base 400, and the plug blocks 201 are plugged and matched with the slots 401 to form a detachable connection. The connection part can be specifically provided with one or more plug blocks 201, as shown in the figure, the number used in actual application is 4, and correspondingly, as shown in the figure, the number of slots 401 is set to 4, and when the plug block 201 is inserted into the slot 401, the clamping ring 200 is installed on the heat dissipation base 400.

[0061] It should be noted that the connecting portion can also be set as a threaded structure; accordingly, a reverse threaded structure corresponding to the threaded structure can be set on the inner wall surface of the heat dissipation base 400, so that when the connecting portion is screwed together through the thread and the reverse thread, the retaining ring 200 is installed on the heat dissipation base 400.

[0062] Specifically, as shown in the figure, the clamping portion includes a plurality of through openings 202 that are centrally symmetrically arranged on the inner and outer wall surfaces of the clamping ring 200, and a limiting clamp block 203 is arranged in each through opening 202. A clamping ring flange 207 arranged along the inner wall surface of the clamping ring 200 is formed on one side of the clamping ring 200 close to the lamp holder 100, and the clamping ring flange 207 and the limiting clamp block 203 form a clamping space for clamping the lens 300.

[0063] Specifically, as shown in the figure, the inner side of each of the limit blocks 203 has a reverse limit positioning slope 204, the lower end of the limit positioning slope 204 is seamlessly connected to the inner wall of the retaining ring, and the upper end of the limit positioning slope 204 is provided with a first clamping surface 205 horizontally protruding from the inner wall of the retaining ring 200, and the clamping space is formed between the first clamping surface 205 and the inner bottom side of the retaining ring flange 207.

[0064] Specifically, as shown in the figure, the lens 300 is a trumpet-shaped structure, the lens 300 has a tail portion with a narrower diameter and a head portion with a wider diameter, and the outer edge of the head portion of the lens 300 is provided with a circle of lens holding flanges 301 protruding horizontally outward, and the lens holding flanges 301 are held in the holding space.

[0065] It should be noted that the lens structure may also be a reflective cup structure, and the outer edge of the reflective cup is also provided with a circle of horizontally protruding retaining flanges.

[0066] Specifically, as shown in the figure, the thickness of the lens holding flange 301 is less than or equal to the thickness of the holding space, and the width of the lens holding flange 301 is the same as the width of the first holding surface 205 .

[0067] Specifically, as shown in the figure, the light emitting component 500 is fixed in the heat dissipation base 400 by a first bolt 402, and the light emitting component 500 is an LED light source.

[0068] Specifically, the installation and disassembly principle of the lens 300 is as follows: in the actual installation process of the lens 300 or the reflective cup, specifically when the head of the lens or the reflective cup is pushed into the clamping ring 200, the lens or the reflective cup holding flange 301 moves along the lower end of the limit block slope 204 toward the upper end, and the limit block 203 penetrating the opening 202 is squeezed outwards. When the lens or the reflective cup holding flange 301 moves beyond the upper end of the limit block slope 204, the limit block 203 penetrating the opening 202 rebounds inwards, and the lens or the reflective cup holding flange 301 is held by the first clamping surface 205 of the limit block 203, and due to the lens The thickness of the lens or reflective cup holding flange 301 is slightly smaller than (or equal to) the distance from the first clamping surface to the clamping ring flange 207, so the lens or reflective cup holding flange 301 can be just clamped between the first clamping surface and the clamping ring flange 207. Furthermore, since the width of the lens or reflective cup holding flange 301 can be the same as (or similar to) the width of the first clamping surface, after the first clamping surface supports the lens or reflective cup holding flange 301, the first clamping surface 205 and the lens or reflective cup holding flange are better fitted, and there will be no insufficient bearing force due to too small a fitting area, and no waste of materials due to making the lens or reflective cup holding flange 301 too wide.

[0069] In addition, there is a method in which the limit block 203 can protrude from the outer wall surface of the retaining ring. When removing the lens or the reflective cup, since the limit block 203 protrudes from the outer wall surface of the retaining ring, the user can find the position of the limit block 203 on the outer wall surface of the retaining ring, and can easily press the first retaining surface 205 of the limit block and push the first retaining surface of the limit block outward. At this time, the lens or reflective cup holding flange 301 is no longer supported by the first retaining surface 205 of the limit block, so that the lens 300 or the reflective cup can be easily removed.

[0070] The lens in the prior art is bound to the light-emitting component, and the specifications of the lamp stand also need to be adapted to the reflective cup, otherwise the reflective cup cannot be installed on the lamp stand, which makes it difficult for existing ceiling lamp products to adjust the light output effect of the lamp body. Therefore, this case proposes a ceiling lamp structure that releases the binding relationship between the light-emitting component 500 and the lens or reflective cup. The light-emitting component 500 is no longer fixed on the lens or reflective cup, and the lens or reflective cup is no longer installed on the lamp stand. Instead, a new clamping ring 200 is set, and the lens 300 is first installed on the clamping ring 200, and then connected to the heat dissipation base 400 through the clamping ring 200.

[0071] Then, when the reflector cup or the lens needs to be replaced, the combination of the clamping ring and the lens can be directly replaced, or the lens can be removed from the clamping ring and replaced, thereby achieving the need to adjust the light output effect.

[0072] Specifically, as shown in the figure, the plug block 201 is protrudingly arranged on the outer side surface 206 of the retaining ring, and a clamping head 210 is arranged at one protruding end of the plug block 201. The clamping head 210 has a protruding clamping head slope surface 211 relative to the outer side surface 208 of the plug block, and a second clamping surface 213 is arranged on the side of the clamping head 210 away from the heat dissipation base 400, and the second clamping surface 213 is perpendicular to the outer side surface 208 of the plug block.

[0073] Specifically, as shown in the figure, a first slot block 212 is arranged on the middle part of the chuck slope surface 211, and a second slot block 209 is correspondingly arranged on the second chuck surface 213. The first slot block 212 and the second slot block 209 are integrally formed with the chuck 210, and the first slot block 212 and the second slot block 209 are vertically aligned structures.

[0074] Specifically, as shown in the figure, a limiting groove 403 is set below the slot 401 of the heat dissipation base 400, and the slot 401 includes a first guide groove 404 for inserting the first slot block 212 and the second slot block 209, and a second guide groove 405 having a slope opposite to the clamping head slope 211 and provided for the clamping head slope 211, and the limiting groove 403 is connected to the first guide groove 404.

[0075] Specifically, the installation and disassembly principle of the clamping ring 200 and the heat dissipation base 400 is as follows: in the specific implementation of installing the clamping ring 200 to the heat dissipation base 400, the first slot block 212 and the first guide groove 404 can facilitate the user to align the clamping head 210 with the slot. After aligning the first slot block and the first guide groove, the user can first push the first slot block into the first guide groove of the slot. Since the first slot block is arranged on the clamping head slope 211, when the first slot block is pushed in, the clamping head slope will also be pushed into the slot, that is, The chuck slope 211 can be pushed in along the opposite slope on the second guide groove 405. When the entire chuck slope 211 is pushed in, the chuck 210 will fall into the limiting groove 403. If the chuck is pulled upward by pulling the snap ring upward at this time, the second clamping surface 213 of the chuck will be supported by the upper groove edge of the limiting groove 403 and will not be able to pop out; and if the snap ring is continued to be pressed downward, the chuck 210 will be supported by the lower groove edge of the limiting groove 403. Therefore, the chuck 210 is first fixed in the vertical direction through the above design.

[0076] At this time, as the clamp head 210 falls into the limiting groove, the second groove block 209 will fall into the first guide groove 404 at the same time, and the two sides of the second groove block 209 will be supported by the groove wall of the first guide groove 404, so that the second groove block cannot move left and right. Since the second groove block is made integrally with the entire clamp head, the clamp head cannot move left and right either, that is, the position of the clamp head in the limiting groove is also fixed, and the retaining ring cannot rotate at will in the heat dissipation base. Therefore, the clamp head is fixed in the horizontal direction through this structure.

[0077] Therefore, when the clamp falls into the limiting groove, the clamp is fixed in the vertical and horizontal directions and cannot move. Since the clamp and the clamp ring are also made in one piece, this structure can ensure that a corner of the clamp ring is firmly connected to the heat dissipation base and cannot fall off easily.

[0078] The present invention proposes a connection method between a clamping ring and a heat dissipation base, and specifically designs a clamping ring including a special clamping head structure, and a heat dissipation base including a special slot structure. Installation and connection can be achieved by simply aligning the clamping head structure of the clamping ring with the slot structure of the heat dissipation base and pressing hard. The slot structure can limit the movement of the clamping head structure in the horizontal and vertical directions after the clamping head structure enters, thereby preventing the clamping ring from moving after being successfully connected to the heat dissipation base, thereby ensuring the firmness and tightness of the connection.

[0079] Specifically, as shown in the figure, the inner wall of the lamp holder 100 is symmetrically provided with a groove block 104 that cooperates with the retaining ring 200, and the retaining ring 200 is provided with no less than two first groove areas and no less than two second groove areas. The first groove areas and the second groove areas are alternately arranged in a ring on the outer side surface 206 of the retaining ring. The first groove areas correspond to the groove block 104 in space, and the second groove areas correspond to the groove block 104 in space.

[0080] In actual applications, the rotary groove blocks 104 are generally designed to be two, symmetrical to each other on the inner wall of the inner ring of the lamp body, so that when the installation of the inner ring of the lamp body and the heat dissipation base is completed, the two rotary groove blocks 104 can be screwed and installed at the same time; and the symmetrical design of the groove blocks can avoid installation on only one side, making the installation more stable.

[0081] There are two first rotary groove areas, which correspond to the groove blocks in space; there are also two second rotary groove areas, which correspond to the groove blocks in space. That is, in practical applications, four slide groove areas are generally set on the heat dissipation base, and they are alternately arranged in a circular manner in the form of "first rotary groove area-second rotary groove area-first rotary groove area-second rotary groove area".

[0082] Specifically, as shown in the figure, the first spiral groove area includes a first groove track 214 arranged on the side of the retaining ring 200 away from the heat dissipation base 400, a second groove track 406 arranged on the side of the heat dissipation base 400 close to the retaining ring 200, and a first baffle 217 connected between the first groove track 214 and the second groove track 406. The first groove track 214, the second groove track 406, the first baffle 217, and the outer side surface 206 of the retaining ring together constitute the first spiral groove area.

[0083] Specifically, as shown in the figure, the height of the first baffle plate 217 is less than or equal to the height of the groove block 104, forming the tail position of the first groove area, and the other end of the first groove area relative to the first baffle plate 217 is provided with a groove entrance composed of a first groove rail 214 and a second groove rail 406, and the height of the groove entrance is greater than the height of the groove block 104, and the first groove area gradually narrows from the groove entrance to the first baffle plate 217.

[0084] Therefore, when the user tightens the lamp body by twisting the inner ring, the groove block 104 can enter the first groove formed by the first groove rail and the second groove rail through the groove entrance. Since the first groove gradually shrinks, the width of the first baffle is slightly less than or equal to the height of the groove block 104. The first groove will slowly resist and gently squeeze the groove block 104, and the first baffle will also block the continued movement of the groove block 104, so that the user can feel that it can no longer be twisted and has been tightened to the tightest.

[0085] When the user twists the inner ring of the lamp body to loosen it, the user can also feel an obvious loosening feedback through the degree of force applied when the rotation groove block 104 changes from a gently squeezed static state to a moving state. Therefore, the user can get a better use feel when using the technical product in this case, and the user can better distinguish the installation status between the heat dissipation base 400 and the inner ring 102 of the lamp body by using the feel.

[0086] Specifically, as shown in the figure, a corrugated belt 223 is provided on the side opposite to the first groove rail 214 and the second groove rail 406 to form a rotational extrusion with the groove block 104. The first groove rail 214 is set as an inclined structure, and the corrugated belt 223 is set at a position of the first groove rail 214 near the tail of the first groove area.

[0087] The function of the corrugated belt is: when the rotating groove block 104 passes through the corrugated belt 223 in an extruded state, it is easy to vibrate, thereby making a "click" sound, which can be used to remind the user that the connection part between the inner ring of the current lamp body and the heat dissipation base has been installed; on the other hand, the corrugated belt can also prevent the groove block from easily retreating.

[0088] In order to achieve a gradual contraction of the first groove rail and the second groove rail, the first groove rail can be designed to be a groove rail with a certain angle of inclination (the inclination is shown in the figure), and the main corrugated belt 223 can be set on the first groove rail; in this case, the heat dissipation base can be disassembled, and the first groove rail and the second groove rail can be disassembled into two parts respectively, as shown in the figure, one is a retaining ring 200, and the other is a heat dissipation base 400; at the same time, when the corrugated belt 223 is severely worn due to excessive use and cannot make a good "click" sound, the user can easily replace the corrugated belt by replacing the retaining ring carrying the first groove rail.

[0089] Specifically, the shape of the corrugated belt is a wave shape with continuous undulations. When the groove block passes, when the user pushes the rotating groove block 104 and encounters the first rising section of the corrugated belt, since the rotating groove block 104 itself is made integrally with the inner ring of the lamp body and does not easily deform, the rotating groove block 104 and the corrugated belt will be squeezed against each other. The corresponding twisting phenomenon is that the user's twisting will produce obvious resistance, preventing the user from continuing to twist.

[0090] If the user gradually applies greater pressure at this time, the groove block 104 and the corrugated belt 223 will both be slightly deformed until the pressure can cause the deformation between the groove block 104 and the corrugated belt to allow the groove block 104 to pass through the first rising interval of the corrugated belt; when the groove block 104 passes through the first rising interval of the corrugated belt in a moving posture, the deformation between the groove block 104 and the corrugated belt will be restored to a certain extent, but because the groove block 104 is in motion and the distance of continuous ups and downs of the corrugated belt is short, the groove block 104 will fall in the second rising interval of the corrugated belt, and will not fall in the first falling interval, and the deformation between the groove block 104 and the corrugated belt will not be completely restored; moreover, this movement of the groove block 104 will continue until the last rising interval of the corrugated belt.

[0091] The corresponding twisting phenomenon is: after the user slightly increases the twisting force, there will be a continuous and obvious twisting bumpy feeling, accompanied by a slight "clicking" sound.

[0092] When the movement of the groove block 104 passes through the last rising interval of the corrugated belt, there will be no subsequent rising interval of the corrugated belt, and the extrusion deformation between the groove block 104 and the rising interval of the corrugated belt will no longer occur, and the deformation between the groove block 104 and the corrugated belt can be restored. Since the distance of continuous undulation of the corrugated belt is short and the descending interval is short, based on the movement speed of the groove block 104, the groove block 104 will fall directly on the first groove rail, and the last descending interval of the corrugated belt will not have a buffering effect on the deformation recovery, that is, the deformation of the groove block and the corrugated belt will be quickly restored. Since the corrugated belt is set on the first groove rail and can be made integrally with the first groove rail, the deformation recovery process of the groove block and the corrugated belt will drive the groove block and the first groove rail to collide and vibrate quickly, thereby producing a crisp impact sound. The corresponding twisting phenomenon is: when the user feels the end of the twisting bump, he will hear a crisp "click" sound.

[0093] Specifically, as shown in the figure, the second spiral groove area includes a third groove rail 215 arranged on the side of the retaining ring 200 away from the heat dissipation base 400, a second groove rail 406 arranged on the side of the heat dissipation base 400 close to the retaining ring 200, and a second baffle 218 connected between the third groove rail 215 and the second groove rail 406. The third groove rail 215, the second groove rail 406, the second baffle 218, and the outer side surface 206 of the retaining ring together constitute the second spiral groove area.

[0094] Specifically, as shown in the figure, the second baffle 218 is arranged at the tail position of the second groove area, and the second groove area is provided with a groove entrance relative to the other end of the second baffle 218, and the width and height of the groove entrance are greater than the height of the groove block 104, and the third groove rail 215 and the second groove rail 406 are parallel to each other;

[0095] An insertion groove 222 communicating with the slot entrance is formed between the second baffle 218 of the second rotary slot area and the first slot rail and the second slot rail of the first rotary slot area.

[0096] Specifically, as shown in the figure, a through hole 219 is provided at the end of the second spiral groove area, and a spring block 216 is provided in the through hole 219. The outer surface of the spring block 216 is higher than the outer side surface 206 of the clamp ring, and the outer surface of the spring block 216 has at least a long slope surface 220 with a smaller slope, and a short slope surface 221 with a larger slope;

[0097] The long slope surface 220 is arranged at the front side of the second groove region in the screw-in direction, and the short slope surface 221 is arranged at the rear side of the second groove region in the screw-in direction.

[0098] When the rotary groove block 104 moves in the second groove formed by the third groove rail and the second groove rail, it will first pass through the long slope 220, and the pressure of the rotary groove block 104 on the long slope 220 will cause the spring block 216 to be compressed inward in the through hole 219. When the rotary groove block 104 passes the highest point of the long slope 220, the spring block will rebound to restore the deformation, causing the short slope 221 to collide and vibrate with the rotary groove block 104, thereby making a "click" sound to prompt the user that the connection between the inner frame 102 of the current lamp body and the heat dissipation base 400 has been installed.

[0099] When the rotating groove block 104 wants to exit the second groove, the groove block needs to pass through the short slope 221 first. Due to the structural properties of the short slope 221, the user needs to use greater force to twist the lamp body inner frame 102 to make the rotating groove block 104 pass through the spring block 216 and exit the second groove.

[0100] In summary, compared with the first groove area, the spring block structure in the second groove area is larger than the corrugated belt structure, and it is less likely to cause the groove block 104 to leave, which is suitable for the installation of ceiling lamps with higher safety factors. Compared with the second groove area, the corrugated belt structure in the first groove area has better screwing feedback. That is, the setting of the first groove area and the second groove area provides users with a variety of installation options, and users can choose the required installation location according to actual needs.

[0101] Moreover, the first baffle 217 and the second baffle 218 may be designed to have different sizes so as to better adapt to the rotating groove blocks 104 of different lamp body inner frames 102, thereby providing users with a variety of installation adaptation options.

[0102] In addition, since both the first groove area and the second groove area are provided on the heat dissipation base, the second baffle of the second groove area can form an insertion groove 222 between the first groove rail and the second groove rail of the first groove area. As shown in the figure, when connecting the lamp holder and the clamping ring, the groove block 104 can be inserted into the insertion groove 222 first. After insertion, the groove block 104 comes to the groove entrance, and the user can screw it at this time; the design of the insertion groove can facilitate the user to quickly find and understand the installation and connection method of the lamp body inner frame and the heat dissipation base.

[0103] The present application proposes a rotatable and screwable ceiling lamp installation structure, and designs a heat dissipation base and a lamp holder that can be tightly connected by screwing, so that the user can disassemble and install the ceiling lamp by screwing the heat dissipation base and the lamp holder, and can replace or repair the lamp body by replacing the lamp holder.

[0104] Specifically, as shown in the figure, the lamp holder 100 includes an outer frame 101 and an inner frame 102 which are inserted inside and outside and rotatably connected to each other. The outer frame 101 and the inner frame 102 are both cylindrical structures. The outer frame 101 and the inner frame 102 are divided into left and right sides with their rotation connection point as the central axis. A first arc-shaped recess 106 is provided on one side of the insertion end of the inner frame 102.

[0105] Specifically, as shown in the figure, a second arc-shaped recess 105 is correspondingly provided on one side of the socket of the outer frame 101 of the lamp body.

[0106] Specifically, as shown in the figure, first mounting holes 104 are symmetrically provided on both sides of the lamp body frame 101 , mounting bosses 107 are correspondingly symmetrically provided on both sides of the lamp body frame 102 , and threaded holes 108 are provided on the outer ends of the mounting bosses 107 .

[0107] Specifically, as shown in the figure, the outer frame 101 and the inner frame 102 of the lamp body are rotatably mounted by means of the second bolt 103 in cooperation with the first mounting hole 104 , the mounting boss 107 , and the threaded hole 108 .

[0108] Specifically, as shown in the figure, the rotation groove block 104 is arranged on the lower inner side of the lamp body inner frame 102 .

[0109] Specifically, the installation principle of the outer frame and the inner frame of the lamp body in this solution is: the outer frame and the inner frame of the lamp body are connected by the "second bolt--mounting hole of the outer frame of the lamp body--threaded hole of the inner frame of the lamp body" method; but the head and the threaded hole of the second bolt are not completely attached to the inner and outer walls of the outer frame of the lamp body through the mounting hole, but a certain gap is left between the inner wall or outer wall of the outer frame of the lamp body, thereby allowing the outer frame of the lamp body to rotate along the threaded portion of the second bolt.

[0110] In general, the structure after the inner frame of the lamp body and the outer frame of the lamp body are connected is: a part of the structure of the inner frame of the lamp body is inserted into the outer frame of the lamp body. In this case, if the outer frame of the lamp body wants to rotate, the inserted end of the inner frame of the lamp body will press against the inner wall of the outer frame of the lamp body to prevent the outer frame from rotating.

[0111] In the present scheme, the wall forming the insertion end of the right part of the inner frame of the lamp body is set as the first arc-shaped depression. It can be understood that the wall that blocks the outer frame of the lamp body from rotating to the right in the initial state is physically cut off. Then, when the outer frame of the lamp body rotates to the right in the initial state, the socket of the right part of the outer frame of the lamp body will obviously not be pressed against the cut-off wall. The socket of the right part of the outer frame of the lamp body will lower its edge height through rotation until the socket of the right part of the outer frame of the lamp body can press against the outer wall of the arc-shaped depression of the right part of the inner frame of the lamp body.

[0112] At the same time, in order to make the outer frame of the lamp body rotatable to a larger angle, another arc-shaped depression can be set along the wall of the socket on the right part of the outer frame of the lamp body. It can be understood that since the socket on the right part of the outer frame of the lamp body also has an arc-shaped depression, the outer frame of the lamp body needs to be rotated to a greater angle so that the socket on the right part of the outer frame of the lamp body can rest against the outer wall of the arc-shaped depression on the right part of the inner frame of the lamp body; that is, it can better meet the user's demand for rotation angle.

[0113] Since the wall along the left part of the insertion end of the lamp body frame is not set as an arc-shaped depression, if the lamp body frame is rotated to the left, the left part of the insertion end of the lamp body ring will abut against the inner wall of the lamp body frame, and thus cannot be rotated to the left. Therefore, when the lamp body frame has been rotated to the right, if you want to restore the light output angle of the lamp body frame in the initial state, you only need to rotate the lamp body frame to the left to the end.

[0114] This case proposes a rotatable installation structure for the lamp body frame, which mainly connects the lamp body frame and the lamp body frame to a rotatable structure by setting a first arc-shaped recess and a second arc-shaped recess. Since the light emitted by the ceiling lamp must pass through the light outlet of the lamp body frame, when the lamp body frame can be rotated based on the lamp body frame, the angle of the light outlet is changed, and the light outlet angle of the light emitted by the ceiling lamp is also changed.

[0115] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0116] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
