Description

Technical Field

[0001] The utility model relates to the technical field of ceiling lamps, and specifically, to a ceiling lamp. Background Art

[0002] Ceiling lamps are more and more widely used in the home lighting environment, and the appearance and function solutions of ceiling lamps also show diversity.

[0003] Currently, in the ceiling lamps on the market, the lamp board is mostly arranged in a way of annular splicing board, and the power control component is arranged in the center of the ceiling lamp inside, and the power control component is installed in the power box. Since the power box is usually made of opaque materials and protrudes from the light-emitting surface of the lamp board, the light emitted by the lamp board will be blocked, and the uniform light emission of the ceiling lamp cannot be achieved.

[0004] Therefore, a more optimized lamp structure needs to be considered. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a ceiling lamp that improves the light emission uniformity of the lamp.

[0006] To achieve the above main purpose, the ceiling lamp provided by the utility model includes a chassis, a lampshade, a light source module and a circuit box. The chassis and the lampshade cooperate to form a receiving cavity, and both the light source module and the circuit box are located in the receiving cavity; the light-emitting surface of the light source module faces the lampshade, and in the direction of the light-emitting surface, the circuit box protrudes from the light-emitting surface; the circuit box is made of a non-metallic light-diffusing material.

[0007] It can be seen from the above solution that the ceiling lamp of the utility model uses a non-metallic light-diffusing material to make the circuit box, so that when the light emitted by the light source module passes through the circuit box, the light can be diffused, reducing the light blockage, improving the dark area caused by the light blockage of the circuit box, and thus playing a role in improving the light emission uniformity of the lamp.

[0008] In a further solution, the circuit box and the chassis cooperate to form a circuit cavity, and a power supply component and an infrared receiver are installed in the circuit cavity; the circuit box is made of a plastic light-diffusing material.

[0009] In a further solution, the plastic light-diffusing material includes polycarbonate material, polymethyl methacrylate material or polystyrene-based plastic.

[0010] It can be seen therefrom that both the power supply component and the infrared receiver are installed in the circuit box, and the plastic diffusion material can shield the electrical components in the power box cavity, playing a role in shielding the internal circuit components, avoiding affecting the appearance, and not affecting the infrared signal reception.

[0011] In a further solution, the circuit box is provided with a protruding portion, and the protruding portion is provided with a power interface through hole.

[0012] It can be seen from this that the circuit box is provided with a convex part, and the power interface through hole is arranged in the convex part, which is convenient for the insertion of the power interface.

[0013] In a further solution, the ceiling lamp further includes a mains connector, and the mains connector is installed on the chassis; the power interface through hole is located on one side of the circuit box close to the mains connector.

[0014] It can be seen from this that arranging the power interface through hole on the side close to the mains connector is convenient for the connection between the mains connector and the power interface, reduces the lead length, and simplifies the structure.

[0015] In a further solution, the light source module includes an LED lamp board and a lens assembly. The LED lamp board is provided with a plurality of surface-mounted LED lamp beads, and the lens assembly is provided with a plurality of lenses. One lens covers at least one surface-mounted LED lamp bead.

[0016] It can be seen from this that the LED lamp board is provided with surface-mounted LED lamp beads. Since the surface-mounted LED lamp beads have a small-angle optical light distribution, it is possible to avoid the influence of peripheral structural parts on the light output effect. And by setting the lens assembly, the overall light emission of the light source module is more uniform and softer.

[0017] In a further solution, the LED lamp board includes two protruding arms and a connecting part connecting the two protruding arms. The two protruding arms and the connecting part cooperate to form a U-shaped groove.

[0018] It can be seen from this that the two protruding arms of the LED lamp board and the connecting part cooperate to form a U-shaped groove, which can optimize the structural setting, improve the utilization rate of the LED lamp board, eliminate the need for splicing and connecting multiple LED lamp boards, and at the same time reserve space to match the mains connector and the power module, significantly improving the utilization rate, reliability, and assembly efficiency of the LED lamp board.

[0019] In a further solution, the circuit box is located in the U-shaped groove.

[0020] It can be seen from this that installing the circuit box in the U-shaped groove can reduce the blockage of light by the circuit box.

[0021] In a further solution, one of the plurality of surface-mounted LED lamp beads is a night light lamp bead, and the night light lamp bead and the corresponding lens cooperate to form a light output angle of 15° to 40°.

[0022] It can be seen from this that by setting one night light lamp bead, it can be used in the night light mode. At the same time, the night light lamp bead and the corresponding lens cooperate to form a light output angle of 15° to 40°, which can improve the light condensation effect and ensure sufficient brightness with only one night light lamp bead.

[0023] In a further solution, the circuit box is provided with a lamp board interface, and the LED lamp board is provided with a power supply interface, and the power supply interface is electrically connected to the lamp board interface; the night light lamp beads are located near the power supply interface and far from the U-shaped groove.

[0024] It can be seen that the night light lamp beads are located near the power supply interface, which can reduce the copper-clad leads of the night light lamp beads in the LED lamp board, avoid interference with the copper attachment of the main light lamp beads, and reduce costs. Moreover, the night light lamp beads are located far from the U-shaped groove, which can avoid being blocked by the devices installed in the U-shaped groove and affecting the light output effect.

[0034] Ceiling lamp embodiment:

[0035] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the ceiling lamp includes a chassis 1, a lampshade 2, a light source module 3 and a circuit box 4. The chassis 1 and the lampshade 2 cooperate to form a receiving cavity 11, and both the light source module 3 and the circuit box 4 are located in the receiving cavity 11. The light-emitting surface of the light source module 3 faces the lampshade 2, and in the orientation of the light-emitting surface, the circuit box 4 protrudes from the light-emitting surface.

[0036] The circuit box 4 is made of a non-metallic light-diffusing material, such as materials like glass, light-transmitting plastics, etc. In this embodiment, the circuit box is made of a plastic light-diffusing material. Preferably, the plastic light-diffusing material is PC (polycarbonate) material, or PMMA (polymethyl methacrylate) material, or PS (polystyrene-based plastic).

[0037] The circuit box 4 cooperates with the chassis 1 to form a circuit cavity 12, and a circuit board 5 is installed in the circuit cavity 12. Refer to Figure 4 , the circuit board 5 is provided with a power supply component 51 and an infrared receiver 52. The power supply component 51 is used to supply power to and control the light source module 3, and the infrared receiver 52 is used to receive infrared control signals to control the operation of the light source module 3. Both the power supply component 51 and the infrared receiver 52 are installed in the circuit box 4. The plastic light-diffusing material can shield the electrical components in the circuit cavity 12, avoiding affecting the aesthetics, and does not affect the infrared receiver 52 from receiving infrared signals.

[0038] Refer to Figure 5 , the circuit box 4 is provided with a protrusion 41, and the protrusion 41 is provided with a power interface through hole 411. As can be seen from Figure 4 , the circuit board 5 is also provided with a power interface 53, and the power interface 53 is arranged at the power interface through hole 411. Setting the power interface through hole 411 on the protrusion 41 can facilitate the insertion of the power interface 53 to connect to the power supply.

[0039] As can be seen from Figure 1 , the ceiling lamp further includes a mains connector 6. The mains connector 6 is installed on the installation position 13 of the chassis 1, and the power interface through hole 411 is located on the side of the circuit box 4 close to the mains connector 6. The mains connector 6 and the power interface 53 are pluggable. Setting the power interface through hole 411 on the side close to the mains connector 6 can facilitate the connection between the mains connector 6 and the power interface, reduce the lead length, and simplify the structure.

[0040] In this embodiment, refer to Figure 6 , the light source module 3 includes an LED lamp board 31 and a lens assembly 32, and the lens assembly 32 covers the LED lamp board 31.

[0041] The LED lamp board 31 includes two protruding arms 311 and a connecting portion 312 connecting the two protruding arms 311. The two protruding arms 311 and the connecting portion 312 cooperate to form a U-shaped groove 313, and both the circuit box 4 and the mains connector 6 are located in the U-shaped groove 313. The two protruding arms 311 and the connecting portion 312 of the LED lamp board cooperate to form a U-shaped groove 313, which can optimize the structural arrangement, improve the utilization rate of the LED lamp board 31, eliminate the need for splicing and connecting multiple LED lamp boards 31, and at the same time reserve space to match the mains connector 6 and the power module, significantly improving the utilization rate, reliability, and assembly efficiency of the LED lamp board 31.

[0042] In addition, the LED lamp board 31 is arranged in a U-shaped structure, which is convenient for improving the material utilization rate during the production of the LED lamp board 31. Refer to Figure 7 , and the two LED lamp boards 31 are arranged such that one protruding arm 311 of one LED lamp board 31 is inserted into the U-shaped groove 313 of the other LED lamp board 31.

[0043] Refer to Figure 8 , the LED lamp board 31 is provided with a plurality of surface-mounted LED lamp beads 314. The lens assembly 32 is provided with a plurality of lenses 321, and one lens 321 covers at least one surface-mounted LED lamp bead 314. The lens 321 is used to adjust the light-emitting angle of the surface-mounted LED lamp bead 314. Preferably, the lens 321 is a convex lens. Since the surface-mounted LED lamp bead 314 has a small-angle optical light distribution, the LED lamp board 31 is provided with the surface-mounted LED lamp bead 314, which can avoid the influence of surrounding structural parts on the light-emitting effect. At the same time, by providing the lens assembly 32, the overall light emission of the light source module 3 is more uniform and softer.

[0044] In this embodiment, one of the plurality of surface-mounted LED lamp beads 314 is a night light lamp bead 3141, and the night light lamp bead 3141 and the corresponding lens 3211 cooperate to form a light-emitting angle of 15° to 40°. By providing one night light lamp bead 3141, it can be used in the night light mode. At the same time, the night light lamp bead 3141 and the corresponding lens 3211 cooperate to form a light-emitting angle of 15° to 40°, which can improve the light-concentrating effect and ensure sufficient brightness with only one night light lamp bead 3141.

[0045] In addition, as can be seen from Figure 2 and Figure 4 , the circuit box 4 is further provided with a lamp board interface 42, the LED lamp board 31 is provided with a power supply interface 315, the power supply interface 315 is electrically connected to the lamp board interface 42, and the night light lamp bead 3141 is located at a position close to the power supply interface 315 and far from the U-shaped groove 313. Preferably, the maximum distance between the night light lamp bead 3141 and the power supply interface 315 is five times the diameter of the lens 321, and the minimum distance between the night light lamp bead 3141 and the U-shaped groove 313 is twice the diameter of the lens 321. The night light lamp bead 3141 is located close to the power supply interface 315, which can reduce the copper-clad leads of the night light lamp bead 3141 in the LED lamp board 31, reduce the interference with the copper-clad leads of the main lamp beads, and reduce the cost. Moreover, the night light lamp bead 3141 is located far from the U-shaped groove 313, which can avoid being blocked by the devices installed in the U-shaped groove 313 and affecting the light-emitting effect.

[0046] As can be seen from the above solution, the ceiling lamp of the present utility model uses a light diffusing material to make the circuit box 4, so that when the light emitted by the light source module 3 passes through the circuit box 4, light diffusion can occur, reducing the light blockage and improving the dark area caused by the light blocking of the circuit box 4, thereby playing a role in improving the light emission uniformity of the lamp.

[0047] It should be noted that the above is only the preferred embodiment of the present utility model, but the design concept of the utility model is not limited thereto. Any non-substantive modifications made to the present utility model using this concept also fall within the protection scope of the present utility model.
