A ceiling lamp is a lamp generally installed on an indoor roof, and a plane structure above the ceiling lamp is generally designed to be a plane in order to match the roof. The ceiling lamp structure in one embodiment of the present application is as shown in fig. 1, and includes a chassis 100, a lamp panel 400, and a lampshade 300. The chassis 100 is used for being mounted against a roof, the lampshade 300 is mounted on the chassis 100, and an accommodating space for mounting the lamp panel 400 is defined between the lampshade 300 and the chassis 100. The lamp panel 400 is fixedly installed on the chassis 100 and located in the accommodating space. Still include protection casing 200, protection casing 200 fixed mounting is on chassis 100, and is located the accommodation space, and lamp plate 400 sets up between chassis 100 and protection casing 200, and lamp plate 400 is covered completely to protection casing 200, plays dustproof and protection against electric shock's function. The through hole is formed in the base plate 100, the guiding hanger 500 is installed at the through hole, one end of the guiding hanger 500 extends into the accommodating space, and the other end of the guiding hanger 500 can protrude out of the upper surface of the base plate 100 so that the ceiling lamp can be conveniently hung. As shown in fig. 2, the shield cover 200 is provided with a fitting hole 210, and the hanger 500 may pass through the fitting hole 210. The hanger 500 is electrically connected to the lamp panel 400.

During installation, the protective cover 200, the lamp panel 400, the chassis 100 and the leading hanger 500 form an independent assembly module 10, the assembly module 10 is directly installed at a connector on an indoor roof, the leading hanger 500 is fixedly connected with the connector, and the leading hanger 500 is electrically connected with the connector. Above-mentioned installation, install the connector on the roof through drawing hanger 500, not only can realize being connected ceiling lamp and connector electricity, and realize ceiling lamp and connector fixed connection, and then simplified the installation, need not install the ceiling lamp with assembly module 10 dismantlement, the dismouting is very convenient, and realize the shade through positions that protection casing 200 easily electrocute such as lamp plate 400, make operating personnel be difficult to take place the electric shock accident, the security has improved greatly.

Wherein, the lamp cover 300 is detachably installed at the assembling module 10, and the lamp cover 300 is used for shielding the shield cover 200. When installing the ceiling lamp, the lamp shade 300 is dismantled with the assembly module 10, is convenient for maintain the assembly module 10, for example adjustment wiring etc.. The lamp housing 300 is generally made of a semi-transparent material and has a function of scattering light so as to make the light more uniform and soft.

The lamp shade 300 shown in the figure only represents a style of the lamp shade 300 of one embodiment, and the lamp shade 300 can cover the lamp panel 400 and the protective cover 200 and can also achieve the technical effect of dust prevention to a certain extent. In some embodiments, the lampshade 300 may be designed in other shapes, and the lampshade 300 is detachably connected with the chassis 100, and the lampshade 300 may be connected with the chassis 100 in a non-closed manner. In the conventional embodiment, since the protection cover 200 is not provided, the dust-proof effect is achieved by the lamp cover 300, but the lamp cover 300 of the conventional embodiment needs to be disassembled to install the ceiling lamp, and thus the electric shock-proof effect is not achieved. Further, since the lamp cover 300 in the conventional embodiment is required to have a dustproof effect, the lamp cover 300 must be hermetically connected to the chassis 100. In this embodiment, the protective cover 200 is hermetically connected to the chassis 100, so that the lampshade 300 can be openly connected to the chassis 100, the shape of the lampshade 300 is not limited to the chassis 100, the lampshade 300 can be designed into various shapes, the characteristic of the single property of the conventional ceiling lamp is improved, and the ceiling lamp is diversified.

As shown in fig. 1 and 2, the base pan 100 is circular, and the upper surface of the base pan 100 for abutting against the roof is substantially planar. The planar arrangement does not strictly require that the top of the chassis 100 be a complete plane. For example, at least three support portions 111 are provided on the top of the chassis 100, and the top ends of the three support portions 111 may be on the same plane. Because the top surfaces of the three supporting parts 111 are on the same plane, the supporting parts 111 can abut against the roof, so that the whole assembly module 10 can stably abut against the roof, and the mounting stability is improved. The heat dissipation of the chassis 100 is facilitated by the support portion 111 abutting against the roof to form a space between the chassis 100 and the roof. For example, the supporting portion 111 may be an elastic member that can be elastically deformed. The hanging device 500 is fixedly connected with the connector on the roof, and due to the different protruding heights of the connector on the roof, if the supporting portion 111 cannot be elastically deformed, the supporting portion 111 cannot be completely abutted against the roof, so that the mounting firmness is reduced. The supporting portion 111 is an elastic member, and the supporting portion 111 can adjust its length along with the gap between the chassis 100 and the roof by elastic deformation of the supporting portion 111, so that the supporting portion 111 can still be supported on the roof. For example, the support 111 may be a spring, and for example, the support 111 may be a sponge.

As shown in FIG. 2, in one embodiment, to facilitate heat dissipation, the chassis 100 may be provided with a plurality of heat sinks 110. When the ceiling lamp is installed on the roof, the bottom of the heat dissipation groove 110 is not attached to the roof, and the heat dissipation capacity is enhanced. For example, as shown in fig. 2, a plurality of heat dissipation grooves 110 may be provided on the top of the base plate 100, and the plurality of heat dissipation grooves 110 are concentrically arranged. The heat dissipation grooves 110 arranged in concentric rings are neatly arranged on the chassis 100, increasing the uniformity of the chassis 100. Since the heat dissipation grooves 110 are provided, the structural strength of the base plate 100 is reduced to some extent, and as shown in fig. 2, a plurality of heat dissipation grooves 110 on the same circular ring are arranged at intervals to form reinforcing ribs 110A between the plurality of heat dissipation grooves 110 on the same circular ring. The chassis 100 has a good heat dissipation effect and high strength by the arrangement of the reinforcing ribs 110A.

In one embodiment, as shown in fig. 1 and 2, the base pan 100 is of a thin-walled design that provides a substantially uniform overall structural thickness of the base pan 100. This not only reduces the weight of the base plate 100, but also saves the raw materials required to machine the base plate 100. Because the ceiling lamp is usually installed on the roof, therefore the ceiling lamp of low weight design is difficult to drop, improves the security. As shown in fig. 1 and 2, the thin wall design is such that the top of the bottom plate 100 is provided with a heat sink 110, and correspondingly, a rib 112 is formed at the bottom of the bottom plate 100. In one embodiment, as shown in FIG. 1, the side of the tray 100 that is intended to abut the roof is referred to as the outboard side, and the side opposite the outboard side is referred to as the inboard side. The inboard of chassis 100 sets up a plurality of beads 112, and these beads 112 are concentric ring-shaped design to form mounting groove 113 between adjacent ring, a plurality of mounting grooves 113 are the annular cover and establish and arrange, and mounting groove 113 is used for installing lamp plate 400. As shown in fig. 1, the lamp panels 400 are arranged in three groups in a concentric circular shape, and each group of circular lamp panels 400 is correspondingly installed in the circular installation groove 113.

In the above embodiment, the protruding ribs 112 are disposed between the adjacent lamp panels 400 arranged in a circular ring shape, and the adjacent lamp panels 400 are separated by the protruding ribs 112. The heat generated by the lamp panel 400 can be quickly transferred to the ribs 112 and then dissipated through the entire chassis 100, thereby greatly improving the heat dissipation efficiency. Because cut off adjacent lamp plate 400 through bead 112, prevent to produce the thermal influence each other between the adjacent lamp plate 400. In one embodiment, the side wall of the rib 112 is an inclined surface, light emitted by the lamp panel 400 directly irradiates the rib 112, scattering occurs through the rib 112, and the light with heat dissipation is transmitted towards all directions due to the inclined arrangement of the side wall of the rib 112, so that the light is scattered more uniformly, and therefore the lamp panel 400 with three groups of concentric rings can emit uniform light. For example, to enhance the scattering effect of the ribs 112, coatings may be provided on the ribs 112, such as metal oxide coatings, which may have a thickness of 0.3 μm to 0.8 μm.

In some embodiments, to improve the heat dissipation efficiency of the chassis 100, the chassis 100 may be made of a metal material with better heat conductivity. For example, the chassis 100 may be made of iron or stainless steel. As another example, the bottom chassis 100 may also be made of an aluminum material, and the bottom chassis 100 made of the aluminum material not only has excellent heat conduction performance, but also the bottom chassis 100 is lighter in weight. In some embodiments, the chassis 100 may also be made of a plastic material.

In one embodiment, the lamp panel 400 includes a plurality of groups and is annularly sleeved. As shown in fig. 1 and 2, three sets of lamp panels 400 are included and arranged in a ring shape. In one embodiment, the Light panel 400 mainly includes a Printed Circuit Board (PCB) and Light Emitting Diode (LED) chip beads disposed on the PCB. The PCB board is the annular setting, and a plurality of LED paster lamp pearl spaced arrange on the PCB board. In the embodiment shown in fig. 1 and 2, each PCB board is provided with only one row of LED patch lamp beads. However, the arrangement of the LED patch lamp beads is not limited to the above embodiments, for example, a plurality of rows of LED patch lamp beads may be disposed on one PCB. As shown in fig. 1, the lighting device further includes a power board 410 connected to the adjacent PCB board, and the power board 410 not only realizes the electrical connection of the adjacent lamp panels 400, but also realizes the fixed connection of the adjacent lamp panels 400, so as to improve the uniformity of the whole lamp panel 400. In one embodiment, the three annularly arranged lamp panels 400 are arranged concentrically. The multiple lamp panels 400 are arranged in a circular ring shape, so that the light emitting area is increased, and the light intensity is improved. And the light that is the lamp plate 400 of ring form arrangement and sends can form more cross light, for example, the light that the lamp plate 400 of inner ring outwards diverges can meet the light that lamp plate 400 of outer loop inwards diverges, and then make hardly exist between the adjacent lamp plate 400 the dead angle region that is covered by light, and the light quantity of inner ring and outward appearance intercrossing is usually with annular central point evenly distributed, consequently, there is not certain blast or region that darkens basically, whole ceiling lamp luminous homogeneity has finally been improved.

In one embodiment, as shown in fig. 1, the lamp panel 400 includes a plurality of groups arranged in an annular manner, each group of the lamp panels 400 is arranged in an annular manner, wherein the lamp panel 400 arranged in an annular manner includes a plurality of segments. That is, each set of the lamp panels 400 arranged in an annular shape is formed by splicing a plurality of segments along arc-shaped extending subsections. For example, in the embodiment shown in fig. 1, the lamp panel 400 at the outermost circle includes a first subsection 411 and a second subsection 412, both the first subsection 411 and the second subsection 412 are semi-annular, a first electrical connector is disposed at an end of the first subsection 411, a second electrical connector is disposed at an end of the second subsection 412, the first electrical connector and the second electrical connector may be a male plug and a female plug, respectively, and after the male plug and the female plug are plugged into each other, the first electrical connector and the second electrical connector are electrically connected, so that the first subsection 411 and the second subsection 412 are electrically connected. Through the mode, each lamp panel 400 which is annularly arranged is designed into the detachable sub-sections, when the LED patch lamp beads on a certain sub-section are damaged, only the sub-section needs to be replaced correspondingly, the whole lamp panel 400 does not need to be replaced, and the maintenance cost is greatly improved. In this embodiment, each sub-segment is used as a replaceable module, and the design of the modularized lamp panel 400 improves the replaceability of the lamp panel 400 and saves the maintenance cost.

As shown in fig. 1, the ceiling lamp includes three lamp panels 400 that are annularly arranged, each annular lamp panel 400 of group specifically is the ring, and three lamp panels 400 that are annularly arranged are concentric and set up. After the assembly module 10 is assembled, the hanging guide 500 is inserted into the middle of the innermost group of lamp panels 400 and is located at the common center of the three groups of lamp panels 400. The three groups of lamp panels 400 are electrically connected through the power panel 410, and the hanging device 500 is electrically connected with the power panel 410.

In one embodiment, as shown in fig. 1, the lamp panel 400 is detachably connected to the chassis 100, and the chassis 100 is provided with a fixing buckle 114, where the fixing buckle 114 is used to fix the lamp panel 400. For example, the fixing buckles 114 are arranged in groups, each group of fixing buckles 114 may be provided with two, and the two fixing buckles 114 are respectively arranged on two sides of the lamp panel 400, so as to realize the blocking of the lamp panel 400. For example, the fixing button 114 may be L-shaped, two L-shaped fixing buttons 114 are disposed opposite to each other, and a hook 115 for hooking the lamp panel 400 is formed at a lower portion of the L-shaped fixing button 114. Of course, the fixing button 114 may be made of an elastic material to facilitate installation of the lamp panel 400. As shown in fig. 1, the holder buckle 114 may be provided on the top wall of the mounting groove 113. The holder buckle 114 may also be provided on the sidewall of the mounting groove 113.

In some embodiments, the lamp panel 400 and the chassis 100 may be detachably connected by other methods, for example, two sides of the hook and loop fastener may be respectively connected to the lamp panel 400 and the chassis 100 by hook and loop fasteners, and then the two sides of the hook and loop fastener are attached together.

In one embodiment, as shown in fig. 1, the protective cover 200 is detachably connected to the chassis 100 to facilitate replacement of a damaged lamp panel 400. Because the protective cover 200 and the chassis 100 form the assembly module 10 as a whole, the assembly module 10 as a whole can be specifically assembled as a whole when leaving a factory, and when the ceiling lamp is installed, the assembly module 10 as a whole is only required to be installed on a roof, and then the lamp shade 300 is covered. The lamp panel 400 is damaged with a low probability, so that the shield 200 is not frequently detached from the chassis 100. To improve the integrity of the assembled module 10, the hood 200 is mounted to the chassis 100 by screws. Specifically, a mounting hole 211 may be formed at the outer circumference of the protection cover 200, and a screw may be screwed to the chassis 100 after passing through the mounting hole 211. The protective cover 200 is connected with the chassis 100 through screws, and the protective cover 200 is difficult to be detached only by hands due to the fact that the protective cover 200 is detached from the chassis 100 through a special detaching tool, so that the protective cover 200 is prevented from being detached randomly to a certain extent, and the effect of preventing electric shock is achieved. The protection cover 200 is made of a transparent material so that the protection cover 200 has a good light-transmitting effect, for example, the protection cover 200 may be made of a transparent plastic material. The surface of the protective cover 200 may be a high-definition light-transmitting surface or a frosted surface. The high-definition light-transmitting surface has a more excellent light-transmitting effect, so that light rays are brighter; the frosting surface has more outstanding scattering effect, makes light softer, and light is more even.

In one embodiment, as shown in fig. 2, the fitting hole 210 in the middle of the shield 200 can pass through the hanger 500. Wherein, the shape of the fitting hole 210 corresponds to the outer circumference shape of the hanger 500, so that the outer wall of the hanger 500 can just fit the inner wall of the fitting hole 210. For example, when the hanger 500 has a cylindrical shape, the fitting hole 210 has a cylindrical shape. The protection cover 200 may have a thin-walled structure, and in order to improve the stability of the assembly of the protection cover 200 and the guiding hanger 500, the stability of the assembly is improved by increasing the adhering surface between the inner wall of the assembly hole 210 and the guiding hanger 500, for example, the inner wall of the assembly hole 210 extends along the length direction of the protection cover 200, so that the outer wall of the protection cover 200 is better attached to the inner wall of the assembly hole 210, a sealing structure is formed, and the dustproof effect is improved.

To further secure the hood 200 to the chassis 100. As shown in fig. 2, four fixing holes 230 are formed in the middle of the protection cover 200, the four fixing holes 230 are uniformly formed in the periphery of the mounting hole 210, and each fixing hole 230 is substantially formed in the middle between the side wall of the mounting hole 210 of the protection cover 200 and the outermost periphery of the protection cover 200, and screws can pass through the fixing holes 230 and be screwed on the chassis 100, so that the middle of the protection cover 200 is prevented from sagging due to the soft material of the protection cover 200 when the ceiling lamp is installed on a roof.

In order to further improve the stability of the installation of the protecting hood 200 on the chassis 100, the protecting hood 200 and the chassis 100 are provided with a positioning structure, as shown in fig. 1, the positioning structure may include a positioning groove 221 disposed on the protecting hood 200 and a positioning block 222 disposed on the chassis 100, when the protecting hood 200 is assembled with the chassis 100, the positioning block 222 is just accommodated in the positioning groove 221, and the inner wall of the positioning groove 221 abuts against the outer wall of the positioning block 222, so as to prevent the protecting hood 200 from rotating relative to the chassis 100. Of course, the positioning groove 221 may be disposed on the chassis 100, and the positioning block 222 may be disposed on the protection cover 200. That is, the positioning structure actually includes a positioning groove 221 and a positioning block 222 that can be clamped with each other, the positioning groove 221 is disposed on one of the protection cover 200 and the chassis 100, and the positioning block 222 is disposed on the other of the protection cover 200 and the chassis 100. In one embodiment, the mounting hole 211 is provided on the positioning groove 221 or the positioning block 222 of the shield cap 200 for the purpose of optimizing the structure.

Fig. 3 is a schematic structural view of the mounting module 10 in the ceiling lamp shown in fig. 1. With reference to fig. 2 and fig. 3, the lamp cover 300 and the chassis 100 in the assembly module 10 are quickly assembled and disassembled through a clamping structure, specifically, the clamping structure includes a first clamping structure 610 and a second clamping structure 620, and the locking of the lamp cover 300 and the assembly module 10 is realized through the clamping cooperation of the first clamping structure 610 and the second clamping structure 620. For example, the first clamping structure 610 is disposed at the periphery of the lamp cover 300, the first clamping structure 610 may be provided with a plurality of second clamping structures 620, the number of the second clamping structures 620 is the same as that of the first clamping structures 610, and the second clamping structures 620 are disposed at the position of the chassis 100 corresponding to the first clamping structures 610 on the lamp cover 300. For example, the first clamping structure 610 and the second clamping structure 620 are both two L-shaped claw-shaped structures, and when the lamp cover 300 is assembled with the assembly module 10, the lamp cover 300 is inserted upwards into the chassis 100, and the lamp cover 300 is rotated, so that the two L-shaped first clamping structures 610 and the two L-shaped second clamping structures 620 are clamped.

In the above embodiment, the lamp cover 300 can be quickly clamped to the chassis 100 by rotating the lamp cover 300, and the lamp cover has the advantage of being convenient to disassemble and assemble. Of course, in other embodiments, the first latch structure 610 and the second latch structure 620 may also include the hook 115, and the first latch structure 610 and the second latch structure 620 may also be quickly latched by rotating the lamp housing 300.

In one embodiment, in order to further improve the stability of the connection between the lamp shade 300 and the chassis 100, that is, the first clamping structure 610 and the second clamping structure 620 can have a locking effect to a certain extent after being clamped or hooked, as shown in fig. 3, the second clamping structure 620 is provided with the elastic sheet 630, the elastic sheet 630 protrudes out of the second clamping structure 620, and when the first clamping structure 610 and the second clamping structure 620 are clamped or hooked, the elastic sheet 630 can abut against the first clamping structure 610, so that the first clamping structure 610 and the second clamping structure 620 have the locking effect after being clamped. For another example, a locking groove may be further disposed on the first clamping structure 610, and after the first clamping structure 610 and the second clamping structure 620 are clamped, the elastic sheet 630 extends into the locking groove, so as to further improve the anti-loosening effect. For another example, the elastic sheet 630 may be disposed on the first clamping structure 610, and after the first clamping structure 610 and the second clamping structure 620 are clamped, the elastic sheet 630 elastically abuts against the second clamping structure 620, so as to achieve the anti-loose effect.
