Description

Technical Field

[0001] The present invention relates to the technical field of ceiling lights, and specifically to ceiling lights.

Background Art

[0002] Ceiling lights are increasingly widely used in home lighting environments, and the solutions related to their appearance and functions also show diversity.

[0003] Currently, inside the ceiling lights on the market, the lamp board is often arranged in the form of a ring-shaped splice plate, the power control unit is arranged to be centrally located inside the ceiling light, and the power control unit is installed in the power box. Since the power box is usually made of non-translucent material and protrudes from the light-emitting surface of the lamp board, the light emitted from the lamp board is blocked, and the achievement of the light-emitting uniformity of the ceiling light cannot be achieved.

[0004] Therefore, it is necessary to study a more suitable lamp structure.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The main object of the present invention is to provide a ceiling light that can improve the light-emitting uniformity of the lamp.

Means for Solving the Problems

[0006] To achieve the above main object, the ceiling light provided by the present invention includes a chassis, a lamp shade, a light source module, and a circuit box. The chassis and the lamp shade together form an accommodation chamber, both the light source module and the circuit box are located inside the accommodation chamber, the light-emitting surface of the light source module faces the lamp shade, and in the direction of the light-emitting surface, the circuit box protrudes from the light-emitting surface, and the circuit box is made of a non-metallic light-diffusing material.

[0007] As can be seen from the above-described technical means, in the sealing light according to the present invention, since the circuit box is made of a non-metallic light-diffusing material, when the light rays emitted from the light source module pass through the circuit box, the light rays can be diffused, thereby reducing the shielding of the light rays, improving the dark part caused by the light shielding of the circuit box, and playing a role in improving the light emission uniformity of the lamp.

[0008] Furthermore, the circuit box forms a circuit cavity together with the chassis, a power supply unit and an infrared receiver are installed in the circuit cavity, and the circuit box is made of a plastic light-diffusing material.

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

[0010] As can be seen from the above, both the power supply unit and the infrared receiver are installed in the circuit box, and the plastic light-diffusing material shields the electrical components in the power supply box, thereby playing a role in shielding the internal circuit unit, avoiding affecting the appearance, and also having no influence on the reception of infrared signals.

[0011] Furthermore, a protrusion is provided on the circuit box, and a power interface through hole is provided on the protrusion.

[0012] As can be seen from the above, since a protrusion is provided on the circuit box and the power interface through hole is provided on the protrusion, it is easy to insert the power interface.

[0013] Furthermore, the sealing light further includes a main power connector attached to the chassis, and the power interface through hole is located on one side close to the main power connector of the circuit box.

[0014] As can be understood from the above, since the power interface through-hole is provided on the side closer to the main power connector, the connection between the main power connector and the power interface becomes easier, the length of the lead wire becomes shorter, and the structure is simplified.

[0015] Furthermore, the light source module includes an LED lamp board and a lens unit. A plurality of patch-type LED lamp beads are provided on the LED lamp board, and a plurality of lenses are provided on the lens unit. At least one patch-type LED lamp bead is covered by one lens.

[0016] As can be understood from the above, the LED lamp board is provided with patch-type LED lamp beads. Since the patch-type LED lamp beads have a small-angle optical light distribution, it is possible to avoid the light-emitting effect being affected by surrounding structures. In addition, due to the provision of the lens unit, the light emission of the entire light source module becomes more uniform and softer.

[0017] Furthermore, the LED lamp board includes two protruding arms and a connection part for connecting the two protruding arms. The two protruding arms and the connection part together form a U-shaped groove.

[0018] As can be understood from the above, by forming a U-shaped groove with the two protruding arms of the LED lamp board and the connection part, the structural design is optimized, the utilization rate of the LED lamp board is improved, the splicing and connection of a plurality of LED lamp boards are no longer required. In addition, due to the reserved space, the main power connector and the power unit are adapted, and the utilization rate, reliability, and assembly efficiency of the LED lamp board are significantly improved.

[0019] Furthermore, the circuit box is located within the U-shaped groove.

[0020] As can be understood from the above, by mounting the circuit box within the U-shaped groove, the shielding of light rays by the circuit box can be reduced.

[0021] Furthermore, one of the plurality of patch-type LED lamp beads is a night lamp bead, and the night lamp bead forms a light-emitting angle of 15° to 40° in combination with the corresponding lens.

[0022] As can be seen from the above, one night lamp bead available in the night lamp mode is provided, and the night lamp bead forms a light-emitting angle of 15° to 40° in combination with the corresponding lens, thereby enhancing the light-collecting effect and ensuring sufficient brightness even when there is only one night lamp bead.

[0023] Furthermore, a lamp board interface is provided in the circuit box, a power supply interface electrically connected to the lamp board interface is provided on the LED lamp board, and the night lamp bead is located close to the power supply interface and away from the U-shaped groove.

[0024] As can be seen from the above, by providing the night lamp bead close to the power supply interface, the copper-coated lead of the night lamp bead on the LED lamp board is shortened, the interference with the copper-coated lead of the main lamp bead is reduced, and the cost can be reduced. In addition, since the night lamp bead is located away from the U-shaped groove, it is possible to avoid the light rays being blocked by the members attached to the U-shaped groove and affecting the light-emitting effect.

[0026] Sealing light embodiment: In this embodiment, as shown in FIGS. 1, 2, and 3, the sealing light includes a chassis 1, a lamp shade 2, a light source module 3, and a circuit box 4. The chassis 1 and the lamp shade 2 together form an accommodation chamber 11, and both the light source module 3 and the circuit box 4 are located inside the accommodation chamber 11. The light-emitting surface of the light source module 3 faces the lamp shade 2, and in the direction of the light-emitting surface, the circuit box 4 protrudes from the light-emitting surface.

[0027] The circuit box 4 is made of a non-metallic light-diffusing material, and examples of such materials include glass and light-transmissive plastics. In this embodiment, the circuit box is made of a plastic light-diffusing material, and as the plastic light-diffusing material, it is preferably PC (polycarbonate) material, PMMA (polymethyl methacrylate) material, or PS (polystyrene-based plastic).

[0028] The circuit box 4 and the chassis 1 together form a circuit cavity 12, and a circuit board 5 is mounted in the circuit cavity 12. Referring to FIG. 4, the circuit board 5 is provided with a power supply unit 51 for power supply control of the light source module 3 and an infrared receiver 52 for receiving an infrared control signal for controlling the operation of the light source module 3. Both the power supply unit 51 and the infrared receiver 52 are mounted in the circuit box 4, and the electrical components in the circuit cavity 12 are shielded by a plastic light diffusing material, thereby avoiding affecting the appearance and also not affecting the reception of the infrared signal by the infrared receiver 52.

[0029] Referring to FIG. 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 FIG. 4, the circuit board 5 is also provided with a power interface 53, and the power interface 53 is provided at the position of the power interface through hole 411. Since the power interface through hole 411 is provided in the protrusion 41, it is easy to insert the power supply into the power interface 53.

[0030] As can be seen from FIG. 1, the sealing light further includes a main power connector 6 mounted at the mounting position 13 of the chassis 1, and the power interface through hole 411 is located on the side close to the main power connector 6 of the circuit box 4. The main power connector 6 is removably connected to the power interface 53. Since the power interface through hole 411 is provided on the side close to the main power connector 6, it is easy to connect the main power connector 6 and the power interface, the length of the lead wire is reduced, and the structure is simplified. In this embodiment, referring to FIG. 6, the light source module 3 includes an LED lamp board 31 and a lens unit 32, and the LED lamp board 31 is covered by the lens unit 32.

[0031] The LED lamp board 31 includes two protruding arms 311 and a connecting portion 312 for connecting the two protruding arms 311. The two protruding arms 311 and the connecting portion 312 together form a U-shaped groove 313, and both the circuit box 4 and the main power connector 6 are located within the U-shaped groove 313. By forming the U-shaped groove 313 with the two protruding arms 311 of the LED lamp board, the structural design is optimized, the utilization rate of the LED lamp board 31 is improved, splicing and connection of multiple LED lamp boards 31 are unnecessary. In addition, due to the reserved space, the main power connector 6 and the power supply unit are adapted, and the utilization rate, reliability, and assembly efficiency of the LED lamp board 31 are significantly improved.

[0032] Moreover, since the LED lamp board 31 is designed in a U-shaped structure, the material utilization rate can be improved when producing the LED lamp board 31. Referring to FIG. 7 for explanation, the two LED lamp boards 31 are designed such that one protruding arm 311 of one of the LED lamp boards 31 is inserted into the U-shaped groove 313 of the other LED lamp board 31.

[0033] Referring to FIG. 8 for explanation, a plurality of patch-type LED lamp beads 314 are provided on the LED lamp board 31. A plurality of lenses 321 are provided in the lens unit 32, and at least one patch-type LED lamp bead 314 is covered by one lens 321. The lens 321 is for adjusting the light-emitting angle of the patch-type LED lamp bead 314. Preferably, the lens 321 is a convex lens. Since the patch-type LED lamp beads 314 are provided on the LED lamp board 31 and the patch-type LED lamp beads 314 have a small-angle optical light distribution, it is possible to avoid the light-emitting effect being affected by surrounding structures. In addition, due to the provision of the lens unit 32, the light emission of the entire light source module 3 becomes more uniform and softer.

[0034] In this embodiment, one of the multiple patch-type LED lamp beads 314 is the night lamp bead 3141. The night lamp bead 3141 and the corresponding lens 3211 together form a light-emitting angle of 15° to 40°. One night lamp bead 3141 available in the night lamp mode is provided. By forming a light-emitting angle of 15° to 40° with the corresponding lens 3211, the light-gathering effect is enhanced, and sufficient brightness can be ensured even when there is only one night lamp bead 3141.

[0035] Also, as can be seen from FIGS. 2 and 4, the circuit box 4 is provided with a lamp board interface 42, the LED lamp board 31 is provided with a power supply interface 315 electrically connected to the lamp board interface 42, and the night lamp bead 3141 is located close to the power supply interface 315 and away from the U-shaped groove 313. Preferably, the maximum distance between the night lamp bead 3141 and the power supply interface 315 is 5 times the diameter of the lens 321, and the minimum distance between the night lamp bead 3141 and the U-shaped groove 313 is 2 times the diameter of the lens 321. By arranging the night lamp bead 3141 close to the power supply interface 315, the copper-coated lead of the night lamp bead 3141 on the LED lamp board 31 can be shortened, the interference with the copper-coated lead of the main lamp bead can be reduced, and the cost can be reduced. Also, since the night lamp bead 3141 is located away from the U-shaped groove 313, it is possible to avoid the light rays being blocked by the members attached to the U-shaped groove 313 and affecting the light-emitting effect.

[0036] As can be seen from the above technical means, in the ceiling light according to the present invention, since the circuit box 4 is made of a light-diffusing material, when the light rays emitted from the light source module 3 pass through the circuit box 4, the light rays can be diffused, thereby reducing the shielding of the light rays, improving the dark part caused by the light shielding of the circuit box 4, and playing a role in improving the light-emitting uniformity of the lamp.

[0037] Specifically, it should be noted that the above are only preferred embodiments of the present invention, and the design concept of the invention is not limited thereto. Any non-substantial corrections implemented in the present invention using this concept shall be included within the protection scope of the present invention.
