Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and more particularly to a lighting device. Background Technology

[0002] Ceiling lights are widely used in indoor lighting and are generally installed on the ceiling.

[0003] Ceiling lights typically consist of a light fixture body and a mounting bracket, with the light fixture body connected to a power cable. The mounting bracket is fixed to the ceiling, and the light fixture body is detachably connected to the mounting bracket. During installation, the cable is concealed between the light fixture body and the ceiling and connects to the power supply wiring within the ceiling.

[0004] After the light fixture is installed, the gap between the light fixture and the ceiling is relatively small, and the cable can easily get stuck between the light fixture and the mounting bracket, resulting in cable damage. Utility Model Content

[0005] The inventors of this application recognized that when installing a ceiling light fixture, the cable on the fixture needs to be connected to the power supply line in the ceiling before the fixture is fixed close to the ceiling. The gap between the fixture and the ceiling is very small, and the portion of the cable outside the fixture is relatively long. During installation, the cable is easily caught between the fixture and the mounting bracket, leading to cable damage. The purpose of this application is to provide a lighting device that solves the problem of a significant difference between the actual lighting effect and the desired lighting effect.

[0006] The basic concept proposed by the inventors of this application is to set up a wiring channel on the mounting bracket and to set up an opening on the side of the lamp body near the ceiling to avoid the cable. When installing the lamp body, the cable is placed in the opening and the wiring channel and passes through the mounting bracket through the wiring channel, so as to avoid the cable being clamped between the lamp body and the mounting bracket.

[0007] This application provides a lighting device, comprising: a lamp body, a mounting bracket, and a cable. The mounting bracket has a wiring channel connecting its outer and inner sides. The back of the lamp body is detachably connected to the mounting bracket, and the back of the lamp body has a protrusion surrounding the mounting bracket, the protrusion having an opening corresponding to the wiring channel. One end of the cable is located inside the lamp body and connected to it, while the other end of the cable is located outside the lamp body and extends through the opening and the wiring channel to the inner side of the mounting bracket. The end of the cable outside the lamp body is used for electrical connection with an external circuit to supply power to the lighting device.

[0008] In some examples, the lamp body is rotatably connected to the mounting bracket, and the wiring channel has a fan-shaped cross-section in a direction perpendicular to the rotation axis of the lamp body.

[0009] In some examples, the mounting bracket has a plurality of first connecting structures on the side facing the lamp body, and the plurality of first connecting structures are distributed along the circumference of the mounting bracket; The back of the lamp body is provided with a plurality of second connecting structures, which are located inside the protrusion and distributed along the protrusion. The second connection structure is snapped into the first connection structure.

[0010] In some examples, one of the first and second connection structures includes a slot, and the other of the first and second connection structures includes a hook that slides into the slot from one end to prevent the lamp body from disengaging from the mounting bracket in a direction away from the mounting bracket.

[0011] In some examples, one end of the slot is provided with a stop protrusion to prevent the hook from disengaging from the slot.

[0012] In some examples, the opening is located in the gap between two adjacent hooks.

[0013] In some examples, the orthographic projection of the protrusion on the back of the lamp body is a fan-shaped ring, and the central angle corresponding to the fan-shaped ring is not less than 270°.

[0014] In some examples, the back of the lamp body is also provided with a wiring hole, which is located on the side of the opening near the edge of the lamp body; The lighting device further includes a cable fixing block, which is connected to the lamp body. The cable fixing block is at least partially located in the wiring hole, and the cable passes through the cable fixing block and is installed in the wiring hole.

[0015] In some examples, the lighting device further includes a suspension rope, one end of which is connected to the mounting bracket; a hanging ring is also provided on the back of the lamp body, and the suspension rope is connected to the hanging ring; the hanging ring is located on the side of the cable fixing block away from the opening, or the hanging ring and the cable fixing block are spaced apart along the circumference of the mounting bracket.

[0016] In some examples, the lamp body includes a back plate, a lampshade, and a circuit board. The back plate and the lampshade are arranged opposite to each other and connected. The protrusion is formed on the side of the back plate facing away from the lampshade. The back plate has a groove on the side facing the lampshade corresponding to the position of the protrusion. The circuit board is disposed in the groove. One end of the cable located inside the lamp body is connected to the circuit board.

[0017] The beneficial effects of the technical solutions provided in this application include at least the following: By creating a protrusion with an opening on the back of the lamp body, and a wiring channel on the mounting bracket connecting the inner and outer sides of the bracket, the lamp body is installed onto the bracket with the opening facing the wiring channel. The protrusion can be close to the ceiling, allowing the cable's outer end to extend through the opening and wiring channel to the inner side of the mounting bracket. Thanks to the support of the protrusion and the protection of the wiring channel, the cable will not be clamped between any of the lamp body, mounting bracket, or ceiling, thus preventing damage during installation.

Detailed Implementation

[0021] Figure 1 This is a schematic diagram of a lighting device provided in an embodiment of this application. The lighting device can be a lamp installed close to a wall or ceiling. As an example, the lighting device can be a ceiling light for installation on the ceiling.

[0022] like Figure 1 As shown, the lighting device includes a lamp body 1, a mounting bracket 2, and a cable 3. The mounting bracket 2 has a wiring channel 2a that connects the outer and inner sides of the mounting bracket 2. The back of the lamp body 1 is detachably connected to the mounting bracket 2. The back of the lamp body 1 has a protrusion 11 surrounding the mounting bracket 2, and the protrusion 11 has an opening 11a that is positioned opposite to the wiring channel 2a.

[0023] One end of cable 3 is located inside and connected to the lamp body 1, while the other end of cable 3 is located outside the lamp body 1 and extends through the opening 11a and wiring channel 2a to the inside of the mounting bracket 2. The end of cable 3 located outside the lamp body 1 is used for electrical connection with an external circuit to power the lighting device. That is, cable 3 has two ends, one end of which is arranged inside the lamp body 1 and electrically connected to the lamp body 1, and the other end of which is located outside the lamp body 1 and is used to connect to an external circuit to power the lighting device.

[0024] By providing a protrusion 11 on the back of the lamp body 1, with an opening 11a, and a wiring channel 2a on the mounting bracket 2 connecting the inner and outer sides of the mounting bracket 2, when the lamp body 1 is installed onto the mounting bracket 2, the opening 11a and the wiring channel 2a are positioned opposite each other, allowing the protrusion 11 to be close to the ceiling. The end of the cable 3 located outside the lamp body 1 can extend to the inner side of the mounting bracket 2 via the opening 11a and the wiring channel 2a. Due to the support of the protrusion 11 and the protection of the wiring channel 2a, the cable 3 will not be clamped between any two of the lamp body 1, the mounting bracket 2, and the ceiling, thus preventing the cable 3 from being clamped and damaged during the installation of the lighting device.

[0025] For example, the lamp body 1 can be circular, and the mounting bracket 2 can be annular. The side of the mounting bracket 2 closest to the edge of the lamp body 1 is the outer side of the mounting bracket 2, and the side furthest from the edge of the lamp body 1 is the inner side of the mounting bracket 2.

[0026] The lamp body 1 has a front and a back. The front of the lamp body 1 can be used to emit light, and the back is the opposite surface to the front. When installing the lighting device, the back of the lamp body 1 faces the ceiling. Figure 2 This is an exploded structural diagram of a lamp body provided in an embodiment of this application, as shown below. Figure 2 As shown, the lamp body 1 includes a back plate 111, a lampshade 112, and a circuit board 33. The back plate 111 and the lampshade 112 are arranged opposite to each other and connected, with a protrusion 11 formed on the side of the back plate 111 facing away from the lampshade 112. A groove 111a is provided on the side of the back plate 111 facing the lampshade 112, corresponding to the position of the protrusion 11. The circuit board 33 is disposed in the groove 111a, and one end of the cable 3 located inside the lamp body 1 is connected to the circuit board 33.

[0027] As an example, circuit board 33 can be fan-shaped to better accommodate it in recess 111a. The thickness of circuit board 33 can be less than or equal to the depth of recess 111a.

[0028] A groove 111a is provided at the position corresponding to the protrusion 11 to accommodate the circuit board 33, which can save space and help reduce the thickness of the lamp body 1, that is, the distance between the front and back of the lamp body 1.

[0029] In some examples, the backplate 111 can be a metal stamping, i.e., a component formed by stamping metal material. Metal stamping is easy to mass-produce and has a uniform thickness. The groove 111a and the protrusion 11 are formed during the stamping process, and the protrusion 11 is formed on the side of the backplate 111 facing away from the lampshade 112 by stamping the groove 111a on the side of the backplate 111 facing the lampshade 112.

[0030] The backplate 111 is a metal component, and the cable 3 can also be connected to the backplate 111 to ground the backplate 111, thereby improving electrical safety. The cable 3 may include a power supply line 301 and a grounding line 302, wherein the power supply line 301 is connected to the circuit board 33, and the grounding line 302 is connected to the backplate 111.

[0031] In other examples, the backplate 111 may also be a non-metallic part, such as an injection-molded part.

[0032] Reference Figure 2As shown, in some examples, the lamp body 1 may also include a wireless communication module 331, which can be mounted on the circuit board 33. The wireless communication module 331 provides wireless communication functionality. For example, it facilitates control of the lamp body 1 via a wireless device. The wireless device may include a remote control, mobile phone, laptop, tablet, etc.

[0033] For example, the wireless communication module 331 may include a Bluetooth module and a Wi-Fi module.

[0034] The wireless communication module 331 can be exposed on the back panel 111. For example... Figure 1 As shown, a backplate opening 111b is provided on the backplate 111, and the backplate opening 111b can be located on the protrusion 11. A circuit board opening 33a is provided on the part of the circuit board 33 opposite to the backplate opening 111b. The wireless communication module 331 is located in the circuit board opening 33a and the backplate opening 111b, and is exposed on the backplate 111 through the backplate opening 111b, which is beneficial to the wireless communication of the wireless communication module 331.

[0035] "Exposed," "exposed to," or "revealed" can refer to something that can be seen or touched from the outside. It can be protruding from the outer surface, flush with the outer surface, or recessed from the outer surface. "Exposed portion" refers to a part that can be seen or touched from the outside. For example, "the wireless communication module 331 is exposed on the back panel 111" can mean that at least a portion of the wireless communication module 331 can be seen or touched from the side of the back panel 111 facing away from the lampshade 112. The wireless communication module 331 can protrude from the surface of the back panel 111 facing away from the lampshade 112, be flush with the surface of the back panel 111 facing away from the lampshade 112, or be recessed from the surface of the back panel 111 facing away from the lampshade 112.

[0036] The lamp body 1 may also include a light source 114, which can be electrically connected to the circuit board 33. As an example, Figure 3 This is a schematic diagram of the structure of a light source provided in an embodiment of this application, such as... Figure 3 As shown, the light source 114 may include a light strip, and the light source 114 may be connected to a connecting wire 113, which is used to connect to the circuit board 33.

[0037] The circuit board 33 can be used to control the operation of the light source 114, such as controlling the light source 114 to turn on or off, and controlling at least one of the light emission brightness and light emission color of the light source 114.

[0038] The light strip may include a flexible circuit board and multiple light-emitting devices located on the surface of the flexible circuit board, and the multiple light-emitting devices may be distributed along the surface of the flexible circuit board. For example, the light-emitting devices may include light-emitting diodes and lamp beads.

[0039] The LED strip can be fixed to the side of the lampshade 112 facing the back panel 111. For example, Figure 4 This is a schematic diagram of the structure of a lampshade provided in an embodiment of this application, as shown below. Figure 4 As shown, the light strip can be arranged along the edge of the lampshade 112. For example, the light strip can be glued or attached to the edge of the lampshade 112 by clips. The light source 114 can be connected to the circuit board 33 via a connecting wire 113. Exemplarily, the connecting wire 113 and the circuit board 33 can be connected via a connector.

[0040] Figure 5 This is an assembly diagram of a cable provided in an embodiment of this application, such as... Figure 5 As shown, the back of the lamp body 1 may also be provided with a wiring hole 1a, which is located on the side of the opening 11a near the edge of the lamp body 1. The lighting device also includes a cable fixing block 31. Figure 6 This is a schematic diagram of the connection between a cable and a cable fixing block provided in an embodiment of this application, as shown below. Figure 6 As shown, the cable fixing block 31 is connected to the lamp body 1. The cable fixing block 31 is at least partially located in the wiring hole 1a. The cable 3 passes through the cable fixing block 31 and is installed in the wiring hole 1a.

[0041] The protrusion 11 is arranged around the mounting bracket 2. The side of the protrusion 11 closer to the mounting bracket 2 is the inner side of the protrusion 11, and the side of the protrusion 11 closer to the edge of the lamp body 1 is the outer side of the protrusion 11. The wiring hole 1a is located on the side of the opening 11a closer to the edge of the lamp body 1. The wiring hole 1a is located on the outer side of the protrusion 11. The end of the cable 3 outside the lamp body 1 extends from the outer side of the protrusion 11 through the opening 11a to the inner side of the protrusion 11, and passes through the wiring channel 2a to reach the inner side of the mounting bracket 2.

[0042] For example, the cable fixing block 31 may have a protrusion 311 on the side near the back plate 111, the cable 3 passes through the surface of the protrusion 311, and the protrusion 311 is inserted into the wiring hole 1a.

[0043] Wiring hole 1a can be provided on back plate 111, and cable 3 extends through wiring hole 1a to the inside of lamp body 1.

[0044] The cable 3 is bent at the wiring hole 1a. By installing a cable fixing block 31 at the wiring hole 1a, the cable 3 can be fixed, reducing the stress at the bend. When the end of the cable 3 outside the lamp body 1 is pulled, the stress generated in the part of the cable 3 inside the wiring hole 1a is reduced. It also prevents the end of the cable 3 inside the lamp body 1 from being pulled, preventing the cable 3 from becoming loose due to pulling on the circuit board 33 or the back plate 111.

[0045] For example, the cable fixing block 31 can be fixedly connected to the back plate 111 by screws 32.

[0046] In some examples, the cable retaining block 31 can be integrally formed on the cable 3.

[0047] The cable 3 may include a metal wire and an insulating sheath, with the insulating sheath wrapping around the metal wire. The cable fixing block 31 may be integrally molded onto the insulating sheath. For example, after the cable 3 is manufactured, a portion of the cable 3 can be placed in a mold, and then injection molded to form the cable fixing block 31, so that the cable fixing block 31 is connected to the insulating sheath as a whole.

[0048] For example, the cable fixing block 31 can be a flexible component, such as a silicone component. When the cable 3 is stretched, the flexible cable fixing block 31 can undergo a certain deformation, which helps to reduce the stress in the cable 3 and prevent the cable 3 from being damaged.

[0049] In some examples, the lamp body 1 is rotatably connected to the mounting bracket 2. Figure 7 This is a schematic diagram of the structure of a mounting bracket provided in an embodiment of this application, as shown below. Figure 7 As shown, the cross-section of the wiring channel 2a in the direction perpendicular to the rotation axis O of the lamp body 1 is a fan-shaped ring, that is, the orthographic projection of the wiring channel 2a on the plane perpendicular to the rotation axis O of the lamp body 1 is a fan-shaped ring.

[0050] When installing the lighting fixture, the mounting bracket 2 is typically fixed to the ceiling first, for example, using expansion screws 23, and then the lamp body 1 is installed onto the mounting bracket 2. The lamp body 1 is assembled with the mounting bracket 2 by rotation, making installation convenient. The wiring channel 2a is set as a fan-shaped ring, so that during the rotation of the lamp body 1, the cable 3 can move from one side of the wiring channel 2a to the other relative to the mounting bracket 2, providing ample space for the cable 3 to move.

[0051] Figure 8 This is a schematic diagram of a mounting bracket and a lamp body provided in an embodiment of this application, in which the mounting bracket 2 and the lamp body 1 are separated. Figure 9 This is a schematic diagram of the structure of a mounting bracket provided in an embodiment of this application. Figure 9 The image shows the side of the mounting bracket 2 facing the lamp body 1, as shown. Figure 9 As shown, in some examples, the mounting bracket 2 has multiple first connecting structures 22 on the side facing the lamp body 1, and the multiple first connecting structures 22 are distributed circumferentially along the mounting bracket 2. The back of the lamp body 1 has multiple second connecting structures 12, which are located inside the protrusion 11 and distributed along the protrusion 11. The second connecting structures 12 are engaged with the first connecting structures 22.

[0052] The first connecting structure 22 and the second connecting structure 12, arranged circumferentially, can stably connect the lamp body 1 and the mounting bracket 2. When assembling the lamp body 1 onto the mounting bracket 2, it is only necessary to alternate the second connecting structure 12 and the first connecting structure 22 circumferentially, and then rotate the lamp body 1 to make the second connecting structure 12 and the first connecting structure 22 snap together accordingly, which is convenient to operate.

[0053] For example, three first connecting structures 22 may be provided, and the three first connecting structures 22 are distributed at equal angular intervals. Three second connecting structures 12 may also be provided, and the three second connecting structures 12 are distributed at equal angular intervals.

[0054] In other possible implementations, the number of first connection structures 22 can also be 2, 4, 5 or more, and the number of second connection structures 12 is the same as the number of first connection structures 22.

[0055] As an example, such as Figure 8 and Figure 9 As shown, the first connecting structure 22 includes a slot 220, and the second connecting structure 12 includes a hook 120. The hook 120 slides into the slot 220 from one end to prevent the lamp body 1 from disengaging from the mounting bracket 2 in a direction away from the mounting bracket 2.

[0056] The lamp body 1 is connected to the mounting bracket 2 by sliding the hook 120 into the slot 220. The hook 120 and the slot 220 have a simple structure and flexible design. The hook 120 slides into the slot 220 from one end. By adjusting the length of the slot 220, the range of rotation that the lamp body 1 can rotate relative to the mounting bracket 2 can be changed, so that the wiring channel 2a is always opposite to the opening 11a, thus preventing the side wall of the wiring channel 2a from pulling the cable 3 during the installation of the lamp body 1.

[0057] The slot 220 can be arc-shaped and has two opposite ends, one of which is open and the other is closed. The hook 120 slides into the open end of the slot 220 and closes the other end of the slot 220, which can prevent the lamp body 1 from rotating too much and causing the hook 120 to slide out from the other end of the slot 220.

[0058] Along the circumferential direction of the arrangement of the multiple slots 220, the open ends of the multiple slots 220 face the same direction. That is, in the circumferential direction of the arrangement of the multiple slots 220, for any two adjacent slots 220, the open end of one slot 220 always faces the closed end of the other slot 220.

[0059] like Figure 9 As shown, one end of the card slot 220 is provided with a stop protrusion 221, which is used to prevent the card hook 120 from disengaging from the card slot 220.

[0060] The stop protrusion 221 can be located at the open end of the slot 220. After the hook 120 passes over the stop protrusion 221 and enters the slot 220, the stop protrusion 221 can prevent the hook 120 from exiting from the open end of the slot 220, thereby making the connection between the lamp body 1 and the mounting bracket 2 more stable.

[0061] like Figure 8 As shown, the opening 11a can be located in the gap between two adjacent hooks 120.

[0062] By placing the opening 11a between adjacent hooks 120, the hooks 120 can be prevented from affecting the arrangement of the cable 3, and in particular, the cable 3 can be prevented from getting tangled in the hooks 120.

[0063] In some other possible implementations, the first connection structure 22 may include a hook 120 and the second connection structure 12 may include a slot 220, that is, the hook 120 is disposed on the mounting bracket 2 and the slot 220 is disposed on the lamp body 1.

[0064] In some examples, the orthographic projection of the protrusion 11 onto the back of the lamp body 1 is a fan-shaped ring, and the central angle corresponding to the fan-shaped ring is not less than 270°.

[0065] For example, the central angle corresponding to the fan ring can be 270°, 280°, 290°, 300°, or 310°.

[0066] The annular protrusion 11 forms a central space to accommodate the mounting bracket 2. The projection of the protrusion 11 onto the back of the lamp body 1 is an annular shape with a central angle of not less than 270°. This means that the central angle corresponding to the width of the opening 11a in the circumferential direction of the protrusion 11 is not greater than 90°. This is to avoid the opening 11a being too wide. By making the opening 11a smaller, while providing sufficient space for cable routing, the surface area of ​​the protrusion 11 that is close to the ceiling is larger, allowing for a more stable installation of the lighting device. Furthermore, making the opening 11a smaller also reduces the amount of dust and other foreign matter entering the wiring channel 2a through the opening 11a.

[0067] In some examples, the top surface of the protrusion 11 can be flush with the surface of the mounting bracket 2 facing away from the lamp body 1, that is, the height of the protrusion 11 protruding from the back of the lamp body 1 is the same as the thickness of the mounting bracket 2 in the direction of the rotation axis O of the lamp body 1. The top surface of the protrusion 11 refers to the surface of the protrusion 11 away from the back of the lamp body 1. In this way, when the lamp body 1 is installed, the gap between the protrusion 11 and the ceiling is smaller, and the lamp body 1 can be closer to the ceiling, which can reduce the amount of dust and other debris entering between the lamp body 1 and the ceiling.

[0068] Figure 10 This is a schematic diagram illustrating the installation process of a lighting device provided in an embodiment of this application, as shown below. Figure 10 As shown, the lighting device may also include a suspension rope 21. One end of the suspension rope 21 is connected to the mounting bracket 2, and the other end of the suspension rope 21 is connected to the lamp body 1.

[0069] During the installation of the lamp body 1 and in daily use, the hanging rope 21 can play a protective role in case the lamp body 1 falls accidentally, preventing the lamp body 1 from falling to the ground, thus avoiding damage to the lamp body 1 and preventing injury from falling.

[0070] like Figure 10 As shown, a hanging ring 13 can be provided on the back of the lamp body 1, and the hanging rope 21 is connected to the hanging ring 13.

[0071] The hanging ring 13 facilitates the connection of the suspension rope 21. For example, the end of the suspension rope 21 away from the mounting bracket 2 can be connected to a hook, which is connected to the hanging ring 13.

[0072] As an example, such as Figure 10 As shown, the lifting ring 13 can be located on the side of the cable fixing block 31 away from the opening 11a.

[0073] Figure 11 This is a schematic diagram of the structure of a lamp body provided in an embodiment of this application. In some other examples, such as... Figure 11 As shown, the hanging ring 13 and the cable fixing block 31 are spaced apart along the circumference of the mounting bracket 2. This prevents the hanging rope 21 and the cable 3 from getting tangled during the installation of the lamp body 1.

[0074] The length of the suspension rope 21 can be no less than the minimum distance from the hanging ring 13 to the edge of the lamp body 1, so that when the lamp body 1 is suspended below the mounting bracket 2 by the suspension rope 21, the edge of the lamp body 1 will not contact the ceiling or the mounting bracket 2, and the lamp body 1 can hang down naturally. This not only facilitates the installation of the lighting device, but also prevents the lamp body 1 from being damaged by collision with the ceiling or the mounting bracket 2.

[0075] The following combination Figure 10 The example shown briefly describes the installation process of a lighting device. The actual installation process of a lighting device may not be unique; for example, the order of some steps may change, new steps may be added, or some steps may be omitted. This is just one example.
