Description

Technical Field

[0001] This utility model relates to the field of lamp body structure technology, and in particular to a metal frame lamp body, ceiling light, chandelier and track light. Background Technology

[0002] A ceiling light is a type of light fixture that is directly installed on the surface of a ceiling (roof), with its body (or most of the body) completely or closely "attached" to the ceiling. Among them, those whose main structural components are made of metal are called metal ceiling lights.

[0003] Existing metal ceiling lights use a back panel with bent edges to press the lampshade, which increases manufacturing costs and makes the lampshade prone to detachment. Additionally, existing metal ceiling lights use external infrared sensors for remote control, but this reduces the overall integrity of the fixture and makes it susceptible to damage. Furthermore, the backlight assembly of existing metal ceiling lights is an integral part of the lamp body, only allowing for backlighting and lacking flexibility, resulting in limited functionality and poor interchangeability.

[0004] Therefore, this utility model patent proposes a metal frame lamp body, a ceiling light, a chandelier, and a track light. Utility Model Content

[0005] The utility model patent provides a metal frame lamp body, ceiling light, pendant light, and track light. It mainly solves the problems of existing metal ceiling lights, which use a back plate edge bending to press the lampshade, resulting in high manufacturing costs and easy lampshade detachment; the use of an external infrared sensor for remote control, which reduces the overall structural integrity of the lamp and makes it prone to damage; and the backlighting component being an integral structure with the lamp body, resulting in the backlighting component being non-removable, unable to flexibly switch the light source direction, having limited functionality, and poor interchangeability.

[0006] This utility model patent proposes a metal frame lamp body, comprising: The faceplate is a ring structure with its ends connected, and one end of it extends inward. The lampshade has a sheet-like structure and is built into the face frame and stacked on the inwardly extending end of the face frame; A pressure ring is built into the face frame and stacked on the lampshade; The back panel is arranged parallel to the lampshade and is detachably connected to the other end of the face frame; the end face of the back panel facing the lampshade forms light.

[0007] Preferably, the lampshade is fixed by a snap-fit ​​mechanism, which engages with the inwardly extending end of the face frame through local elastic deformation. The pressure ring is an elastic retaining ring, and the pressure ring is set in the face frame by an elastic interference fit.

[0008] Preferably, an inner frame is formed on the end face of the face frame facing the back plate, and the inner frame is provided with annular spaced cutouts; The end face of the pressure ring facing the back plate is recessed to form an anti-slip groove; the fastener moves along the depth direction of the inner frame and cooperates with the anti-slip groove to fix the pressure ring and the lamp cover; The back plate has a limiting hole, and the fastener cooperates with the inner frame along the limiting hole to fix the back plate and the front frame.

[0009] Preferably, it further includes: A reflector is disposed on the inner side of the pressure ring.

A connector is formed on the end face of the back plate away from the face frame, and the connector is configured to cooperate with the connecting hole. The connector is aligned with one end of the connecting hole, allowing the connector to enter the connecting hole. The back plate is rotated to move the connector toward the other end of the connecting hole and engage it.

[0012] Preferably, the power supply box further includes: A spring clip is fixed to the edge of the end face of the power supply box away from the back plate, and the spring clip partially covers the connection hole; When the connector enters the connecting hole along one end of the connecting hole, it squeezes the spring piece, and when the connector moves to the other end of the connecting hole, it releases the spring piece, causing the spring piece to block the connector from moving in the opposite direction.

[0013] Preferably, the power supply box further includes: The buckle has one end fixed to the edge of the end face away from the back plate of the power box, and the other end of the buckle has a protruding wrench position on the outer side; the inner side of the buckle has a locking groove that is provided to avoid gaps with the end of the connector. When the connector moves to the other end of the connecting hole, the buckle rotates along the fixed end and causes the engaging groove to fit over the connector, fixing the position of the connector.

Detailed Implementation

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Existing metal ceiling lights use a backplate edge bending structure to press the lampshade, resulting in high manufacturing costs and the lampshade being prone to falling off; the use of external infrared sensors for remote control reduces the overall structural integrity of the lamp and makes it more susceptible to damage; and the backlighting component is an integral part of the lamp body, making the backlighting component non-removable, unable to flexibly switch the light source direction, resulting in limited functionality and poor interchangeability.

[0022] Example 1 like Figures 1-7 As shown, to solve the above problems, this embodiment proposes a metal frame ceiling light, including a face frame 110, a lampshade 120, a retaining ring 130, and a back plate 140; the face frame 110 has a ring structure with its ends connected, and one end of it extends inward; the lampshade 120 has a sheet-like structure and is built into the face frame 110 and stacked on the inwardly extending end of the face frame 110; the retaining ring 130 is built into the face frame 110 and stacked on the lampshade 120; the back plate 140 is arranged parallel to the lampshade 120 and is detachably connected to the other end of the face frame 110; light is formed on the end face of the back plate 140 facing the lampshade 120.

[0023] Preferably, in this embodiment, the face frame 110 is made of aluminum profile, which is extruded, bent into a circle, and then welded. Its two ends protrude for connection, and the middle is hollow. It is not limited to the fact that the height of the hollow middle of the face frame 110 is slightly greater than the sum of the height of the pressure ring 130 and the thickness of the lampshade 120.

[0024] Preferably, in this embodiment, the lampshade 120 is made of plastic sheet material, which has bending characteristics. The diameter of the lampshade 120 is slightly smaller than the inner diameter of the face frame 110. During assembly, the lampshade 120 can be bent and placed into the face frame 110. The pressure ring 130 is also made of aluminum profile material. After bending it into a circle, a section is left on one side and not closed. By bending and deforming the pressure ring 130 inward, its diameter can be reduced and placed into the face frame 110. In this embodiment, due to the circular elastic tension of the pressure ring 130, it will automatically open and fit into the inner groove of the face frame 110 after being placed in.

[0025] Preferably, an inner frame 111 is formed on the end face of the face frame 110 facing the back plate 140, and the inner frame 111 is provided with annular spaced cutouts; an anti-slip groove 131 is formed on the end face of the pressure ring 130 facing the back plate 140; the set screw moves along the depth direction of the inner frame 111 and cooperates with the anti-slip groove 131 to fix the pressure ring 130 and the lampshade 120. In this embodiment, the lampshade 120 is locked in contact with the large surfaces of the face frame 110 and the pressure ring 130, and the diameter of the lampshade 120 is much larger than the L-shaped edge at the lower end of the face frame 110, so that the lampshade 120 is pressed and fixed to the face frame 110, and the lampshade 120 will not slip out under force, greatly reducing or even eliminating the risk of the lampshade 120 falling off due to deformation.

[0026] Preferably, the back plate 140 has limiting holes, and fasteners are used to fix the back plate 140 and the face frame 110 together with the inner frame along the limiting holes. Alternatively, the back plate 140 can be directly locked into the groove at the upper end of the face frame 110 using self-tapping screws, without occupying other space, thus narrowing the thickness of the face frame 110 and effectively saving manufacturing difficulty and cost. The lampshade 120 has a certain limit to its deformation. This design narrows the thickness of the face frame 110, allowing the lampshade 120 to be installed even when the overall height of the face frame 110 is relatively reduced, while also increasing the luminous area of ​​the lamp.

[0027] In this embodiment, the structure of the face frame 110, pressure ring 130 and back plate 140 described above can effectively reduce the thickness of the assembled lamp body and improve the structural compactness.

[0028] More specifically, it also includes a reflector 150 disposed on the inner side of the pressure ring 130.

[0029] Preferably, the height of the reflector 150 is equal to the height of the pressure ring 130.

[0030] Preferably, the inner side of the lower end of the pressure ring 130 is designed with a hook groove 132, and the reflector 150 can be directly inserted into the hook groove 132 for fixation.

[0031] In this embodiment, the reflector 150 covers the cut ends of the pressure ring 130, ensuring the aesthetics of the inner side of the lamp and reducing light loss of the lamp body.

[0032] More specifically, it also includes a sensor 160; a light-shielding sheet 111 is provided extending along the inner side of the end of the face frame 110 away from the back plate 140, and a first light-transmitting hole is provided on the light-shielding sheet 111; a second light-transmitting hole 121 is provided on the lampshade 120; the sensing end of the sensor 160 passes through the second light-transmitting hole 121 and the first light-transmitting hole in sequence.

[0033] Preferably, in this embodiment, the sensor 160 is an infrared sensor 160, and the outer diameter of its sensing head is equal to the inner diameter of the first light-transmitting hole and the second light-transmitting hole 121, thereby improving the overall integrity of the lamp body surface.

[0034] Preferably, in this embodiment, after the sensor head of the sensor 160 is fixed through the lamp cover 120 and the face frame 110, the lamp cover 120 is clamped on the sensor 160 by a nut, so as not to damage the original dustproof structure of the lamp.

[0035] In this embodiment, since the light shield 111 is only provided on the lamp cover 120 and the face frame 110 of the lamp body, the impact of adding the sensor 160 on the outer surface of the lamp body is reduced, and its original structural integrity is maintained.

[0036] More specifically, it also includes a power box 180 fixedly connected to the back plate 140 via a safety rope 170; the power box 180 has strip-shaped connection holes 181 spaced along its edge; a connector 141 is formed on the end face of the back plate 140 away from the face frame 110, and the connector 141 is configured to cooperate with the connection hole 181; one end of the connector 141 is aligned with one end of the connection hole 181, so that the connector 141 enters the connection hole 181, and the back plate 140 is rotated to move the connector 141 toward the other end of the connection hole 181 and engage and fix it.

[0037] Preferably, there are three safety ropes 170, evenly spaced circumferentially. The safety ropes 170 are secured to three pre-installed rivet studs on the back plate 140. In this embodiment, the three safety ropes 170 provide structural stability, preventing the lamp from tilting and facilitating wiring and installation.

[0038] Preferably, the back plate 140 is also pre-installed with three rivet nuts, three step screws (i.e. connectors 141) are locked on the rivet nuts, and three safety ropes 170 correspond one-to-one with the positions of the step screws, which facilitates the alignment of the step screws with the connection holes 181 on the power box 180.

[0039] Preferably, in this embodiment, the connecting hole 181 adopts a strip structure with a large hole at one end and a small hole at the other. The stepped screw enters the connecting hole 181 through the large hole. By rotating the back plate 140 and the face frame 110 to assemble the lamp body, the stepped screw moves along the length of the connecting hole 181 to the small hole end, thus fixing the lamp body and the power box 180 vertically. It is not limited to designing the small hole end of the connecting hole 181 as an anti-slip protrusion structure A, that is, the height of the outer connecting structure at the small hole end is slightly higher than the height of the small hole. The three stepped screws are connected and rotate horizontally. Since there is no axis at the center of rotation, there is always an inward force in one direction during rotation. The anti-slip protrusion structure A has a large slope when sliding in, making assembly easy, and a small slope when sliding out, requiring relatively more force to disassemble.

[0040] In this embodiment, by aligning the connecting hole 181 with the connector 141, the lamp body and the power box 180 can be assembled without fasteners, reducing the assembly difficulty and the possibility of detachment without external force after assembly.

[0041] More specifically, a spring tab 142 is formed on the edge of the end face away from the back plate 140 of the power box 180, and the spring tab 142 partially covers the connection hole 181; when the connector 141 enters the connection hole 181 along one end of the connection hole 181, it squeezes the spring tab 142 and releases the spring tab 142 when the connector 141 moves to the other end of the connection hole 181, so that the spring tab 142 blocks the connector 141 from moving in the opposite direction.

[0042] Preferably, in this embodiment, there is at least one spring piece 142, which is configured to cooperate with the stepped screw.

[0043] Preferably, in this embodiment, the spring piece 142 includes an anti-slip structure, and the anti-slip structure is fixed to the power box 180 by fasteners or welding and is arranged adjacent to the connection hole 181. The spring piece 142 is perpendicular to the plane where the connection hole 181 is located.

[0044] Preferably, in this embodiment, the elastic force of the spring piece 142 needs to be designed according to the weight of the lamp body.

[0045] In this embodiment, the design of the spring piece 142 further reduces the possibility of the connector 141 detaching from the connection hole 181.

[0046] Example 2 like Figures 1-6 and Figure 8As shown, in order to solve the aforementioned problems, this embodiment proposes a metal frame ceiling light, which has a structure that is basically the same as that of Embodiment 1. The difference is that the power box 180 of this embodiment is provided with a buckle 183 to replace the spring piece 142. The buckle 183 is fixed to the edge of the end face of the power box 180 away from the back plate 140, and the other end of the buckle 183 has a protruding wrench position. The inner side of the buckle 183 has a locking groove that is provided to avoid gaps with the end of the connector 141. When the connector 141 moves to the other end of the connecting hole 181, the buckle 183 rotates along the fixed end and causes the locking groove to fit over the connector 141, fixing the position of the connector 141.

[0047] Preferably, the buckle 183 is made of a metal elastic material, and the engaging groove has a circular protrusion. When assembling, the buckle 183 should fit tightly against the upper wall of the side wall groove of the power box 180. At the same time, the vertical width of the side wall groove should be greater than the wall thickness of the buckle 183 plus the thickness of the protrusion so that the buckle 183 can be inserted and assembled. Because the buckle 183 is elastic and the upper wall of the power box is tightly fitted, when the buckle 183 is moved, the circular protrusion will cause the buckle 183 to deform and move up and down when it meets the groove wall of the power box. When it is pulled out and pushed in, the protrusion will limit and lock the buckle 183, so that the buckle 183 will not rotate around the axis in its natural state.

[0048] Preferably, when fixing the positioning shaft to the buckle 183, anti-loosening nuts, thread-locking adhesive, or rivets are used. Ordinary screws and nuts can easily loosen and fail during the rotation and deformation of the buckle 183.

[0049] In this embodiment, the inner wall of the power box is provided with a positioning post and a corresponding side slot. When the lever position of the latch 183 is moved, the latch 183 will move in a circular trajectory around the positioning axis. When the lever position of the latch 183 touches the outer wall, the inward movement stops, and the engagement groove on the latch 183 will lock the stepped screw, making the stepped screw unable to move, thereby preventing the lamp body from slipping off. When the latch 183 is moved outward, the head of the latch 183 contacts and abuts against the slot of the power box, and the outward movement of the latch 183 stops. At this time, the engagement groove of the latch 183 disengages from the stepped screw, and the stepped screw can slide. At this time, the lamp body can be twisted and disassembled.

[0050] Example 3 like Figure 9 and Figure 10 As shown, in order to solve the aforementioned problems, this embodiment proposes a metal frame chandelier, which includes a ceiling light of embodiment 1 or embodiment 2, as well as a ceiling structure 210, a hanging wire 221 and a power cord 222; the ceiling structure 210 is installed on an external fixed surface, the hanging wire 221 connects the ceiling structure 210 and the power box 180, and the power cord 222 is located at the center of the hanging wire 221.

[0051] Preferably, in this embodiment, there are three suspension wires 221. First, the three suspension wires 221 ends are locked onto the power box 180 with nuts. Then, the power cord 222 is connected and the power box 180 and the lamp body are tightened. The three holes of the suspension wires 221 locked into the power box 180 are the same as the holes for expansion screws when surface mounting. This design can improve the space utilization rate inside the power box 180.

[0052] Preferably, the ceiling structure 210 includes a ceiling plate 211, a mounting bracket 212, and a decorative cover 213. The ceiling plate 211 is installed on the ceiling, and its lower end face forms a hanging groove 214 for suspending the crossbeam 215 on the mounting bracket 212. The mounting bracket 212 is assembled with a power cord 222. The periphery of the ceiling plate 211 is provided with a rivet joint insertion hole for the hanging wire 221. Three hanging ropes pass through the decorative cover 213 and are inserted into the rivet joint for fixing. The next step is to insert the rivet of the suspension wire 221 into the corresponding hole of the ceiling plate 211. The suspension wire 221 is made of steel wire rope wrapped with a layer of transparent soft rubber. When the suspension wire 221 is inserted into the hole of the ceiling plate 211 and is subjected to downward pulling force, the suspension wire 221 will slide through the anti-detachment structure B of the suspension wire 221. The width of the anti-detachment structure B after its two sides bulge inward is smaller than the diameter of the suspension wire 221 after being wrapped with rubber, but larger than the diameter of the steel wire itself. By utilizing the deformable property of the rubber coating, the suspension wire 221 is not easy to come out and fall off after it is stuck in.

[0053] Preferably, the nut and decorative cover 213 are passed through the power cord 222 in sequence, then locked onto the hanging plate and connected. Next, the crossbeam 215 on the mounting bracket 212 is hung into the hanging groove 214 on the ceiling plate 211. Finally, the decorative cover 213 is pushed up to the top and the nut is locked.

[0054] In this embodiment, the lamp body and power box 180 are suspended by the suspension wire 221. When the metal frame lamp is large and heavy, it is difficult for the user to hold the lamp and connect the wires at a high altitude. The present invention is that the wiring at the lamp body end can be pre-connected on the ground. After the suspension wire 221 is installed in the insertion rope rivet joint, the lamp is connected and fixed to the ceiling plate 211, and there is no need to use extra hands to hold the lamp.

[0055] In addition, the user can easily operate the lamp without taking their hands off when connecting the input cable. The mounting bracket 212 has three terminals on one side, for a total of six, allowing the lamp to be wired for emergency / DALI and other applications requiring multiple connection ports. The mounting bracket 212 also has a cable clamp to effectively solve the safety issue of preventing cable loosening. When the mounting bracket 212 is hung in the mounting groove 214 of the ceiling plate 211, the weight of the lamp will cause the mounting bracket 212 to exert a downward force. The mounting groove 214 is a circular groove, and the crossbeam 215 on the mounting bracket 212 is also circular. At this time, the lamp body may sway left and right. However, when the decorative cover 213 is pushed in, the upper part of the decorative cover 213 will hit the ceiling and be fixed, preventing it from moving upwards. When the nut is tightened, the nut will also exert an upward pushing force on the decorative cover 213. After the decorative cover 213 hits the ceiling, it will exert a reaction pushing force on the nut, thus tightening the mounting bracket 212 and the ceiling plate 211 to ensure that the lamp will not sway or fall during use. Based on this principle, if the height allows, the nut can be recessed or protruding, and with proper shaping, it will make the lamp more aesthetically pleasing.

[0056] Example 4 like Figure 10 and Figure 11 As shown, in order to solve the aforementioned problems, this embodiment, in addition to the ceiling light of Embodiments 1 and 2, also includes a ceiling structure 210 and a hanging rod 223. The ceiling structure 210 is the same as the ceiling structure 210 described in Embodiment 3, except that the power cord 222 is built into the hanging rod 223. During installation, the flange is locked to the power box 180, and then the hanging rod 223 is tightened to the flange on the power box 180. The lamp body is connected, the power cord 222 is passed through the hanging rod 223, the nut and decorative cover 213 are passed through the hanging rod 223 in sequence, the mounting bracket 212 is tightened to the hanging rod 223 and the wire is connected, the crossbeam 215 on the mounting bracket 212 is hung into the hanging groove 214 on the ceiling plate 211, and finally the decorative cover 213 is pushed up to the top and the nut is locked.

[0057] In this embodiment, since the hanging rod blocks the power cord 222, the product has a simple and beautiful appearance and is easy to install. In addition, it uses the same materials as the embodiment 3. When the mounting bracket 212 is hung in the ceiling plate 211, the lamp body is hung on the ceiling plate 211 and will not fall off, so there is no need to hold the lamp by hand.

[0058] Furthermore, since Embodiments 3 and 4 share materials, their versatility and economy are enhanced. For example, the ceiling plate 211, decorative cover 213, and mounting bracket 212 are shared by the suspension wire 221 / suspender rod. The internal and external threaded flanges are connected to the nuts in the suspension wire 221. In the suspension rod, the internal thread connects to the suspension rod, and the external thread connects to the nut. They are assembled in the power box 180 and connected to the other end of the suspension rod. The flange is also fixed with two screws. This effectively solves the problem of difficult assembly and easy misalignment of the lamps caused by the traditional method of clamping the power box 180 with two nuts on the suspension rod.

[0059] Example 5 like Figure 12 As shown, in order to solve the aforementioned problems, this embodiment also proposes a metal frame pendant light. In addition to the lamp body of the ceiling light described in Embodiments 1 and 2, it also includes a guide rail power supply 230, a universal joint 240, and a connecting cover 250. The guide rail power supply 230 is connected to the universal joint 240, and then locked onto the connecting cover 250 with a nut. Finally, the connecting cover 250 is connected to the lamp body with screws to realize the guide rail installation. The rotation angle is adjusted by the universal joint 240.

[0060] Example 6 like Figure 13 and Figure 14 As shown, in order to solve the aforementioned problems, this embodiment also proposes a metal frame ceiling light and pendant light. Based on the structure of any one of embodiments 1 to 5, it further includes a backlighting component 300 stacked in a ring structure on the ceiling light back plate 140. The backlighting component 300 is detachably connected to the back plate 140. A spring pin 310 is formed on the end face of the backlighting component 300 facing the back plate 140 for electrical connection with the back plate 140. A light source plate 320 is provided inside the backlighting component 300, and the light from the light source plate 320 extends towards the end of the backlighting component 300 away from the back plate 140.

[0061] Preferably, in this embodiment, the backlight assembly 300 and the back plate 140 are magnetically fixed. In this embodiment, when the user installs the lamp using the structures of Embodiments 1 and 2 (surface mounting) or the structures of Embodiments 3 to 5 (hanging mounting), the backlight assembly can be removed or replaced after the lamp is assembled and fixed, making the usage more flexible.

[0062] Preferably, in this embodiment, the backlight component 300 can be assembled from two semi-circular arc structures.

[0063] Preferably, in this embodiment, the backlight cover 330 of the backlight assembly 300 is made of a semi-transparent silicone strip. Utilizing the flexibility of silicone and the matching groove with the profile, the silicone strip can be inserted into the profile along the arc without coming out. At the same time, the designed profile protrusion will leave a sealing groove after the end caps are welded to both ends of the profile. When the backlight cover 330 is at both ends of the backlight body of the profile, the silicone end face can be inserted into the sealing groove, so that there is no gap on the front of the backlight, which is dustproof and aesthetically pleasing.

[0064] In this embodiment, the lamp body of the backlight assembly 300 is fixed to the light source board 320 and the magnet with screws and nuts, effectively saving the thickness and width of the backlight assembly 300. During installation, the magnet is placed precisely into the positioning groove of the back plate 140, which can fix it vertically by the magnetic attraction and horizontally by the positioning groove, so that the backlight can be placed in a specific position without moving or deviating. The two middle magnets are close to the power tapping spring 310, so that the power tapping spring 310 and the live pad of the lamp body can be accurately aligned. The magnets on both sides are close to the end face of the profile, ensuring that the two arc surfaces of the backlight are smoothly connected and not easily misaligned. After the two halves of the backlight are assembled, they form a whole circle, and the light emission is uniform and beautiful.

[0065] In summary, Embodiments 1 to 6 present a metal frame lamp body, ceiling light, pendant light, and track light. By optimizing the internal structure of the lamp body and adjusting the fixing method of the infrared sensor head, the structure can be adapted to various installation methods such as surface mounting, hanging wire, hanging rod, and guide rail. The backlight structure and the multi-power supply layout are also adjusted, which improves the functionality and aesthetics of the lamp.

[0066] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
