Description

Technical Field

[0001] This utility model relates to lighting devices, and more particularly to a ceiling light. Background Technology

[0002] Ceiling lights are light fixtures that are attached to or embedded in the ceiling. Like chandeliers, they are the main lighting equipment in a room and are frequently chosen for various places such as homes, offices, and entertainment venues. LED lights are characterized by being mercury-free, non-toxic, free of electromagnetic pollution, free of harmful radiation, energy-saving, environmentally friendly, and having a long lifespan, which has led to their increasingly widespread use.

[0003] Ring-shaped ceiling lights are a common type of ceiling light. Their circular shape, smooth lines, and simple, elegant design allow for more even light distribution, thus fully illuminating the entire room. Compared to other shapes like round ceiling lights, their light distribution is more uniform, reducing the likelihood of localized insufficient brightness and making the interior space brighter and more comfortable. For example, Chinese Patent Application No. 202323533483.5 discloses a ring-shaped illumination ceiling light where a ring-shaped light-shielding component is located around the perimeter of the mounting base. This component has an inner ring-shaped light-shielding wall and an outer ring-shaped light-shielding wall protruding from the mounting base. A gap is formed between the inner and outer ring-shaped light-shielding walls, and the main lighting strip is positioned within this gap. The light from the main lighting strip, which is dispersed laterally, is blocked by the inner and outer ring-shaped light-shielding walls.

[0004] However, the mounting base of this ceiling light is disc-shaped, which does not match the overall ring design, requiring additional lighting compensation. Therefore, further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ceiling light that addresses the shortcomings of the existing technology, ensuring that the light fixture is circular in shape and easy to install.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a ceiling light, including an annular lamp body, characterized in that: an annular mounting groove is formed on the top of the lamp body, and the ceiling light also includes a back cover assembly for mounting the lamp body to an external mounting base, the back cover assembly including a back cover installed into the mounting groove.

[0007] The back cover used to mount the lamp body is also ring-shaped, which maintains the overall ring shape of the ceiling light, saves material on the back cover, and makes it easy to install onto the lamp body.

[0008] Furthermore, to reduce the installation difficulty of the back cover and improve the machining accuracy of its mounting point with the lamp body, the back cover is composed of at least two cover plates spliced ​​together. The back cover assembly also includes a connecting component disposed at the splicing position of two adjacent cover plates in the circumferential direction, thereby splicing the cover plates into a whole and installing the back cover with the lamp body.

[0009] Furthermore, each connecting component includes a first bracket covering the top surface of the rear cover, a second bracket covering the bottom surface of the rear cover, and a pin connecting to the lamp body. The first and second brackets are positioned correspondingly to cover the seam between the two cover plates, and the first and second brackets are also fixed to each other. Through the design of the two brackets, not only can the seam of the rear cover be covered, but it can also be fixed to the lamp body, thereby realizing the installation of the external mounting base, the rear cover, and the lamp body.

[0010] Furthermore, to prevent deformation of the back cover due to stress, each cover plate has a groove at its circumferential end. When two adjacent cover plates are spliced ​​together, the corresponding two grooves are spliced ​​together to form a clearance groove. Each bracket of the connecting assembly has a first mounting hole in the middle, which corresponds to the clearance groove, so that screws can pass through to fix the back cover assembly to the external mounting base.

[0011] Furthermore, to facilitate the fixing of the two brackets and the back cover, each bracket is also provided with a second mounting hole, so that the screw can pass through the first bracket, the cover plate of the back cover and the second bracket from top to bottom to connect and fix the back cover and the two brackets.

[0012] Furthermore, to facilitate the installation of the pin and the lamp body and their positioning after installation, the pin is disposed on the bottom surface of the second bracket. The pin includes a neck extending downward from the bottom surface of the second bracket and a head located at the lower end of the neck, wherein the outer diameter of the head is larger than that of the neck.

[0013] The lamp body also includes a connecting bracket for engaging with a pin. The connecting bracket includes a fixing part and an insertion part. The insertion part is formed on the fixing part and surrounds a slot and a limiting groove that communicate with each other. The slot and the limiting groove are arranged adjacent to each other along the circumference of the lamp body. The shape and size of the slot are adapted to the head of the pin, and the shape and size of the limiting groove are adapted to the neck. The size of the limiting groove is smaller than the head, so that after the pin passes through the slot from top to bottom, it rotates until the head abuts against the bottom of the insertion part located on the outer periphery of the limiting groove, so that the position of the pin and the connecting bracket is relatively fixed.

[0014] Furthermore, to prevent the lamp body from accidentally falling during disassembly and assembly, at least one of the second brackets of the connecting component has a slot formed on one end along the circumference of the rear cover. The slot is formed by the end face of the second bracket being recessed along the circumference of the rear cover. The same connecting component also includes a safety rope, which includes a spherical snap-fit ​​portion at the top and a slender connecting portion. The connecting portion is connected and fixed to the lamp body, and the snap-fit ​​portion is inserted into the slot from the end face of the second bracket through the slot.

[0015] Furthermore, to enhance the stability of the safety rope connection, the connection assembly also includes a spring plate, which is fixedly mounted on the second bracket and positioned corresponding to the slot. The spring plate applies a downward force to the locking part and locks it into the slot.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the back cover used to install the lamp body is also ring-shaped, which can maintain the overall ring shape of the ceiling light, save the material of the back cover, and can be easily installed on the lamp body; the back cover is segmented and spliced ​​and the seams are fixed by brackets. Through the design of two brackets, not only can the seams of the back cover be covered, but it can also be fixed to the lamp body, thereby realizing the installation of the external mounting base, the back cover and the lamp body.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0032] See Figures 1-6 A type of ceiling light, a ring-shaped ceiling light, includes a ring-shaped light body 1 and a ring-shaped back cover assembly 2, the back cover assembly 2 being used to mount the light body 1 to an external mounting base, such as an indoor ceiling.

[0033] The lamp body 1 includes a lamp housing 11, a light source 12 disposed within the lamp housing 11, and a lampshade 13 illuminating the light path of the light source 12. The cross-section of the entire assembly formed by the three components is annular, particularly circular. In this embodiment, in the installed state, the longitudinal cross-section of the lamp housing 11 is U-shaped with the opening facing downwards, and the lampshade 13 is disposed at the opening at the bottom of the housing 11.

[0034] The aforementioned rear cover assembly 2 is disposed on the top of the lamp body 1, i.e., the top of the lamp housing 11 in this embodiment. The rear cover assembly 2 includes an annular rear cover 21, a terminal block 22, and a connecting assembly 23 for mounting the rear cover 21 and the lamp body 1. A mounting groove 111 is formed on the top of the lamp housing 11. The mounting groove 111 is also annular, especially circular, and is formed by a downward indentation from the top surface of the lamp housing 11. The rear cover 21 of the rear cover assembly 2 is used to be installed into the mounting groove 111. The terminal block 22 is fixed to the bottom surface of the rear cover 21 and embedded into a notch 112 formed on the lamp housing 11. The notch 112 is formed by a downward indentation from the top surface of the lamp housing 11, which partially cuts off the mounting groove 111, thus making the mounting groove 111 a partially closed circular ring. The terminal block 22 is used for the light source 12 inside the lamp body 1.

[0035] As mentioned above, the mounting groove 111 is annular, and the back cover 21 is also annular. For ceiling lights with a relatively large diameter, if the back cover 21 is directly made into a complete ring, it would not only require high machining precision for both the mounting groove 111 and the back cover 21, but would also be very inconvenient to install. Therefore, in this embodiment, the back cover 21 is composed of at least two sections, as shown in the figure, three arc-shaped cover plates 211 spliced ​​together. The cover plates 211 are relatively fixed to each other by the aforementioned connecting component 23.

[0036] Combination Figures 5-13The number of connecting components 23 matches the number of cover plates 211, as shown in the figure, there are three. They are set at the splicing position of two adjacent cover plates 211 in the circumferential direction, which can not only splice multiple cover plates 211 into one piece, but also install the rear cover 21 to the lamp body 1. Each connecting component 23 includes a first bracket 231 covering the top surface of the rear cover 21, a second bracket 232 covering the bottom surface of the rear cover 21, and a pin 233 connecting to the lamp body 1. The first bracket 231 and the second bracket 232 are positioned correspondingly to cover the seam between two cover plates 211. Each cover plate 211 has a groove 212 formed at its circumferential end. After two adjacent cover plates 211 are spliced, the corresponding two grooves 212 are spliced ​​to form an approximate circle to form a clearance groove, which is a through groove. Each bracket of the connecting component has a first mounting hole 234 in the middle, which is positioned corresponding to the clearance groove, allowing screws to pass through and fix the rear cover component 2 to the ceiling. In addition, each bracket may have a second mounting hole 235 at its corner, through which screws can pass from top to bottom through the first bracket 231, the cover plate 211 of the rear cover 21, and the second bracket 232 to connect and fix the rear cover 21 and the two brackets.

[0037] A pin 233 is disposed on the bottom surface of the second bracket 232, which includes a neck 2331 extending downward from the bottom surface of the second bracket 232 and a head 2332 located at the lower end of the neck 2331. The outer diameter of the head 2332 is larger than that of the neck 2331. The lamp body 1 also includes a connecting bracket 14 for engaging with the pin 233. The connecting bracket 14 may include a fixing part 141 and an insertion part 142. The fixing part 141 may be a generally hollow cuboid, which is fixedly installed in the lamp housing 11. The insertion part 142 is formed on the fixing part 141, and its top extends upward through the top of the lamp housing 11 and protrudes into the mounting groove 111. The insertion part 142 forms a slot 1421 and a limiting groove 1422 that communicate with each other. The slot 1421 and the limiting groove 1422 are arranged adjacent to each other along the circumference of the lamp body 1. The shape and size of the slot 1421 are adapted to the head 2332 of the pin 233, while the shape and size of the limiting groove 1422 are adapted to the neck 2331. The limiting groove 1422 is smaller than the head 2332; this smaller size means that, in the installed state, the projection of the limiting groove 1422 onto the horizontal plane falls within the projection range of the head 2332 onto the horizontal plane. The pin 233 can pass through the slot 1421 from top to bottom until the head 2332 is below the insertion part 142. Afterward, the neck 2331 can rotate along the limiting groove 1422, causing the head 2332 to abut against the bottom of the insertion part 142 at the outer periphery of the limiting groove 1422, thus fixing the positions of the pin 233 and the connecting bracket 14, enabling the rotational installation of the back cover assembly 2 and the lamp body 1.

[0038] A slot 236 is formed on one end of the second bracket 232 along the circumference of the rear cover 21. The slot 236 can be formed by the end face of the second bracket 232 being recessed along the circumference of the rear cover 21, that is, the slot 236 penetrates the end face of the second bracket 232. Preferably, the slot 236 and the pin 233 are located at opposite ends of the second bracket 232 along the circumference of the rear cover 21. The connecting assembly 23 also includes a safety rope 237, which includes a spherical snap-fit ​​portion 2371 at the top and an elongated connecting portion 2372. The connecting portion 2372 is connected and fixed to the lamp body 1. The snap-fit ​​portion 2371 can be snapped into the slot 236 from the end face of the second bracket 232 through the slot 236. The connecting component 23 also includes a spring piece 238, which is fixedly mounted on the second bracket 232 and is positioned corresponding to the slot 236. It can apply a downward force to the locking part 2371 to lock it in the slot 236, thereby preventing the safety rope 237 from freely coming out of the slot 236.

[0039] The safety rope 237 and the spring 238 together constitute the anti-derailment component. The anti-derailment component can be installed on only one second bracket 232 or on each second bracket 232.

[0040] During installation, the pin 233 and the connecting bracket 14 can be rotated together first, and then the locking part 2371 of the safety rope 237 can be inserted into the spring piece 238. Thus, when the rear cover assembly 2 and the lamp body 1 are opened for maintenance, repair or disassembly, the lamp body 1 will remain connected to the rear cover assembly 2 after the pin 233 and the connecting bracket 14 are disconnected, and will not fall directly. When it is necessary to completely remove the lamp body 1, pressure can be applied to the safety rope 237 to make it move circumferentially relative to the slot 236, and it can be disengaged from the end face of the second bracket 232.

[0041] The installation method of the back cover assembly 2 of this utility model ensures that the back cover 21 will not be deformed under force when the ceiling light is installed. Instead, the force is applied at the connection between the two brackets and the lamp housing 11 (connecting bracket 14 and its installation position), which can ensure a good ceiling installation state for a long time.
