Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a bidirectional ceiling light. Background Technology

[0002] Ceiling lights are a type of lighting device widely used in various indoor spaces. They achieve effective lighting in a specific space by being installed flush with the ceiling or wall.

[0003] Currently, to expand the lighting area of ​​ceiling lights, multiple independent light-emitting components and lampshades are often used to achieve multi-directional light emission. For example, a type of dual-light-emitting ceiling light in the prior art uses a first group of LED beads that emit light downwards at the bottom of the base and a second group of LED beads that emit light laterally on the side of the base, along with corresponding lampshades. This results in a relatively complex structure, as the two groups of LED beads are not on the same plane. In actual production, this requires separate steps for production and installation, and the internal wiring is also relatively complex, leading to cumbersome production steps, high production costs, and thus affecting production efficiency.

[0004] Therefore, it is necessary to provide a bidirectional ceiling light with a simpler structure and lower production cost to improve production efficiency. Utility Model Content

[0005] In view of the technical problems of high manufacturing costs and low efficiency caused by the complex structure and wiring of existing double ceiling lights, this utility model provides a bidirectional light-emitting ceiling light.

[0006] A bidirectional ceiling light includes a base and a lampshade. The base is recessed inward to form a receiving cavity. A conical hollow cylinder for reflecting and guiding light is provided at the bottom of the receiving cavity. The small-diameter end of the conical hollow cylinder is connected to the bottom of the receiving cavity, dividing the bottom of the receiving cavity into an inner bottom surface and an outer bottom surface. A plurality of LED beads are installed on both the inner bottom surface and the outer bottom surface. The lampshade includes a main lampshade and a side lampshade. The main lampshade is located above the side lampshade and connected to the side lampshade. The receiving cavity is fitted onto the outside of the side lampshade, such that the large-diameter end of the conical hollow cylinder abuts against the inner edge of the main lampshade.

[0007] Furthermore, the lamp bead plate includes several annular lamp plates arranged concentrically from the bottom center of the receiving cavity to the edge, and several lamp beads are sequentially installed on each annular lamp plate.

[0008] Furthermore, the annular light panel includes a first annular light panel and a second annular light panel mounted on the inner bottom surface, and a third annular light panel mounted on the outer bottom surface, wherein the first annular light panel, the second annular light panel and the third annular light panel are arranged concentrically in sequence.

[0009] The lamp bead plate

[0010] Furthermore, each of the annular light panels is composed of several arc-shaped light panels.

[0011] Furthermore, the receiving cavity is a cylindrical cavity.

[0012] Furthermore, the main lamp cover and the side lamp cover are integrally formed.

[0013] Furthermore, the middle part of the side lamp cover protrudes outward to form a cover portion; when the receiving cavity is fitted onto the outside of the side lamp cover, the edge of the receiving cavity abuts against the lower end face of the cover portion.

[0014] Furthermore, it also includes a fixing ring, the inner side of which extends inward to form a fixing platform, and several cylinders are provided below the fixing platform; the main lamp cover is provided with several first circular holes corresponding to the cylinders; the cylinders are inserted into the corresponding first circular holes, so that the fixing ring is sleeved on the outside of the side lamp cover and abuts against the upper end surface of the cover body.

[0015] Furthermore, the large-diameter end of the conical hollow cylinder extends outward to form a mounting platform, which is provided with a plurality of mounting holes, and the cylinder is provided with a plurality of first threaded grooves; the cylinder is inserted into the corresponding first circular hole and mounting hole in sequence, and is threadedly connected to the corresponding first threaded groove by a first screw passing through the mounting hole.

[0016] Furthermore, a hollow cylinder is fitted around the small-diameter end of the conical hollow cylinder. One end of the hollow cylinder is connected to the outer side of the conical hollow cylinder, and the inner surface of the other end is connected to the outer surface of the conical hollow cylinder through a connecting block. Each connecting block is provided with a second threaded groove. The bottom of the receiving cavity is provided with several second circular holes that correspond one-to-one with the second threaded grooves. The chassis is connected to the corresponding second threaded groove by passing through the second circular hole with a second screw.

[0017] Furthermore, it also includes a fixed base frame, the outer periphery of which is provided with several L-shaped snap-fit ​​grooves; the center of the receiving cavity protrudes outward to form a groove, and the outer side of the groove protrudes inward to form a mounting groove; the inner sidewall of the mounting groove is provided with several snap-fit ​​blocks corresponding to the L-shaped snap-fit ​​grooves, the fixed base frame is installed in the mounting groove, and the corresponding snap-fit ​​blocks are embedded in the L-shaped snap-fit ​​grooves, so that the fixed base frame and the chassis are detachably connected.

[0018] The beneficial effects of this utility model are as follows: This utility model provides a bidirectional light-emitting ceiling light. By setting a conical hollow cylinder for reflecting and guiding light in the receiving cavity formed by the chassis, the bottom of the receiving cavity is divided into an inner bottom surface and an outer bottom surface. Lamp bead plates are respectively set on the inner bottom surface and the outer bottom surface. Thus, the light emitted by the lamp bead plate on the inner bottom surface is guided and reflected by the inner surface of the conical hollow cylinder to the main lamp cover, and the light emitted by the lamp bead plate on the outer bottom surface is guided and reflected by the surface of the conical hollow cylinder to the side lamp cover. This achieves bidirectional light emission from the side and bottom of the ceiling light, thereby expanding the light-emitting area of ​​the ceiling light.

[0019] Compared to existing bidirectional ceiling lights, the LED chips of this invention are all located in the same cavity, eliminating the need for separate slots on the side of the ceiling light to install LED chips and provide light sources for the side lampshade. This not only simplifies the structure of the bidirectional ceiling light but also helps reduce production and wiring costs and improve production efficiency. Attached Figure Description

[0030] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0031] refer to Figure 1 and Figure 4 As shown, a bidirectional ceiling light includes a base 1, a lampshade 2, and a fixed base frame 3. In this embodiment, the base 1 is cylindrical in shape.

[0032] Specifically, refer to Figure 2 , Figure 4 and Figure 8 As shown, the chassis 1 is recessed inward to form a receiving cavity 4, and a conical hollow cylinder 5 for reflecting and guiding light is provided at the bottom of the receiving cavity 4. In this embodiment, the conical hollow cylinder 5 is a partition with reflective surfaces on both the inner and outer sides; or a white opaque light guide plate.

[0033] The small-diameter end of the conical hollow cylinder 5 is connected to the bottom of the receiving cavity 4, dividing the bottom of the receiving cavity 4 into an inner bottom surface 41 and an outer bottom surface 42; a plurality of lamp bead plates 6 are installed on both the inner bottom surface 41 and the outer bottom surface 42. In this embodiment, the receiving cavity 4 is a cylindrical cavity.

[0034] The lamp bead plate 6 includes several annular lamp plates (not shown in the figure) arranged concentrically from the bottom center to the edge of the receiving cavity 4, and several lamp beads 61 are sequentially installed on each annular lamp plate. In this embodiment, the annular lamp plates 6 are composed of several arc-shaped lamp plates, which helps to reduce the production difficulty and cost of the required lamp plates. Each lamp bead 61 is provided with a lens (not shown in the figure), which can converge the light emitted by the lamp bead 61, so that the originally divergent light becomes a collimated beam with a certain direction and intensity, so that more light can be concentrated to illuminate the target area, thereby improving the light utilization rate and improving the uniformity of illumination.

[0035] The light emitted from the LED bead plate 6 on the inner bottom surface 41 is guided and reflected onto the main lampshade 21 through the inner surface of the conical hollow cylinder 5, and the light emitted from the LED bead plate 6 on the outer bottom surface 42 is guided and reflected onto the side lampshade 22 through the surface of the conical hollow cylinder 5, thereby achieving bidirectional light emission from the side and bottom of the ceiling light, thus expanding the light-emitting area of ​​the ceiling light.

[0036] All the LED bead boards 6 are located on the bottom surface of the same receiving cavity 4, so there is no need to specially cut grooves to install the side-emitting LED bead boards 6. This makes the structure of the lamp relatively simple. In actual production, there is no need to produce and install in steps. The internal wiring is also simplified, which helps to reduce the difficulty of production, reduce the production cost, and thus improve the efficiency of production.

[0037] The annular light panel includes a first annular light panel 62 and a second annular light panel 63 installed on the inner bottom surface 41, and a third annular light panel 63 installed on the outer bottom surface 42, wherein the first annular light panel 62, the second annular light panel 63 and the third annular light panel 64 are arranged concentrically in sequence.

[0038] By employing a structure consisting of a first annular light panel 62, a second annular light panel 63, and a third annular light panel 64 arranged concentrically, the annular light panels can emit light from different positions and angles compared to setting strip light panels, making the light distribution inside the receiving cavity 4 more uniform and improving the lighting effect.

[0039] refer to Figure 3 and Figure 5 As shown, the lampshade 2 includes a main lampshade 21 and a side lampshade 22. The main lampshade 21 is located above and connected to the side lampshade 22. The receiving cavity 4 is sleeved and installed on the outside of the side lampshade 22, such that the large-diameter end of the conical hollow cylinder 5 abuts against the inner edge of the main lampshade 21. In this embodiment, the main lampshade 21 and the side lampshade 22 are integrally formed, which facilitates installation and production.

[0040] The side lamp cover 22 protrudes outward from the middle to form a cover portion 221; when the receiving cavity 4 is fitted and installed on the outside of the side lamp cover 22, the edge of the receiving cavity 4 abuts against the lower end face of the cover portion 221.

[0041] refer to Figure 2 , Figure 4 as well as Figure 7 As shown, the outer periphery of the fixed base frame 3 is provided with several L-shaped snap-fit ​​grooves 31; the center of the receiving cavity 4 protrudes outward to form a groove 43, and the outer side of the groove 43 protrudes inward to form a mounting groove 44; the inner sidewall of the mounting groove 44 is provided with several snap-fit ​​blocks 441 corresponding to the L-shaped snap-fit ​​grooves 31, the fixed base frame 3 is installed in the mounting groove 44, and the corresponding snap-fit ​​blocks 441 are embedded in the L-shaped snap-fit ​​grooves 31, so that the fixed base frame 3 and the chassis 1 are detachably connected.

[0042] The L-shaped locking slot 31 includes a vertical slot and a horizontal slot, with one end of the vertical slot directly connected to the horizontal slot, and the horizontal slot and the vertical slot being set at a 90-degree angle. One end of the vertical slot is connected to the opening of the L-shaped locking slot 31, and the other end of the vertical slot is connected to the horizontal slot. The end of the horizontal slot away from the vertical slot is a closed end. In actual installation, the fixed base frame 3 can be fixedly installed on a wall or indoor ceiling. The locking block 441 first enters the vertical slot vertically along the opening 23. After reaching the bottom of the vertical slot, the ceiling light is rotated to move the locking block 441 horizontally to the closed end of the horizontal slot, so that the locking block 441 is limited and locked in the horizontal slot. This achieves the fixed installation of the ceiling light and the fixed base frame 3. The detachable design helps to improve the efficiency of disassembly and assembly.

[0043] refer to Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the bidirectional ceiling light also includes a fixing ring 7. The inner side of the fixing ring 7 extends inward to form a fixing platform 8. Several cylinders 81 are provided below the fixing platform 8. Several first circular holes 211 corresponding to the cylinders 81 are provided on the main lamp cover 21. The cylinders 81 are inserted into the corresponding first circular holes 211, so that the fixing ring 7 is sleeved on the outside of the side lamp cover 22 and abuts against the upper end face of the cover part 221.

[0044] The large-diameter end of the conical hollow cylinder 5 extends outward to form a mounting platform 51. The mounting platform 51 is provided with a plurality of mounting holes 52. The cylinder 81 is provided with a plurality of first threaded grooves 811. The cylinder 81 is inserted into the corresponding first circular hole 211 and mounting hole 52 in sequence, and is threadedly connected to the corresponding first threaded groove 811 by a first screw 9 passing through the mounting hole 52.

[0045] A hollow cylinder 10 is fitted on the outer side of the small-diameter end of the conical hollow cylinder 5. One end of the hollow cylinder 10 is connected to the outer side of the conical hollow cylinder 5, and the inner surface of the other end is connected to the outer surface of the conical hollow cylinder 5 through a connecting block 11. Each connecting block 11 is provided with a second threaded groove 111. The bottom of the receiving cavity 4 is provided with a plurality of second circular holes 45 corresponding one-to-one with the second threaded grooves 111. The base plate 1 is threadedly connected to the corresponding second threaded groove 111 by a second screw 12 passing through the second circular hole 45.

[0046] The installation process of the bidirectional ceiling light provided by this utility model is as follows: First, the cylinder 81 is inserted sequentially into the corresponding first circular hole 211 and mounting hole 52, so that the fixing ring 7 is sleeved on the outside of the side lamp cover 22 and abuts against the upper end face of the cover part 221. Then, a first screw 9 passes through the mounting hole 52 and is threadedly connected to the corresponding first threaded groove 811, thus completing the connection between the fixing ring 7, the lamp cover 3 and the conical hollow cylinder 5. Second, the base 1 with the conical hollow cylinder 5 installed is sleeved on the ceiling light through its receiving cavity 4. The outer side of the lampshade 22 is positioned such that the large-diameter end of the conical hollow cylinder 5 abuts against the inner edge of the main lampshade 21, and the edge of the receiving cavity 4 abuts against the lower end face of the cover part 221, thus connecting the chassis 1 and the lampshade 3. At this time, the second circular hole 45 corresponds one-to-one with the second threaded groove 111 of the connecting block 11, and then the chassis 1 passes through the second circular hole 45 through a second screw 12 and is threadedly connected to the corresponding second threaded groove 111 on the connecting block 11, thereby achieving a fixed connection between the chassis 1 and the conical hollow cylinder 5, and completing the assembly of the ceiling light.

[0047] The present invention provides a bidirectional light-emitting ceiling light in which all the lamp bead plates 6 are located in the same receiving cavity 4, eliminating the need to separately cut grooves on the side of the ceiling light to install the lamp bead plates 4 to provide light source for the side lamp cover. In addition, the main lamp cover 21 and the side lamp cover 22 of this application are integrated, which not only simplifies the structure of the bidirectional light-emitting ceiling light, but also makes the overall structure simple and easy to disassemble and install, and helps to reduce production and wiring costs and improve production efficiency.
