Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically a circular skylight lamp head. Background Technology

[0002] Existing skylights typically use Rayleigh diffusers to achieve a blue sky effect, but this design has significant limitations. A single optical effect cannot meet the diverse lighting needs of users, only presenting a monotonous blue sky effect. The complex installation structure of the diffuser often requires additional fasteners and seals, increasing assembly difficulty and production costs. Traditional installation methods result in exposed edges, severely affecting the overall aesthetics of the luminaire. Furthermore, insufficient precision in the fit between the light source and the diffuser can easily lead to uneven light distribution or light spot misalignment. Utility Model Content

[0003] The purpose of this utility model is to provide a circular skylight head to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a circular skylight head, comprising: a lampshade, the lampshade being circular and having an opening at the bottom; a heat sink, the heat sink being fixed to the top of the inside of the lampshade, and a light source being installed below the heat sink; a fog blue diffuser plate, the fog blue diffuser plate covering the bottom opening of the lampshade; a snap-fit ​​assembly, the snap-fit ​​assembly being disposed between the bottom edge of the lampshade and the fog blue diffuser plate; and a reflector cup, the reflector cup being disposed outside the light source, the light-concentrating surface of the reflector cup facing the fog blue diffuser plate, for converging the light from the light source onto the surface of the fog blue diffuser plate to form a light spot.

[0005] In one possible implementation, the axis of the reflector is vertically aligned with the center of the fog blue diffuser.

[0006] In one feasible implementation, the light source is a point light source and is located at the focal point of the reflector.

[0007] In one feasible implementation, the snap-fit ​​assembly includes: an annular elastic protrusion that extends horizontally along the inner edge of the lower end of the lampshade, the annular elastic protrusion having an annular groove recessed into the inner side of the lampshade, and the edge of the fog blue diffuser plate snapping into the annular groove.

[0008] In one feasible implementation, the groove edge of the annular groove has an arc surface structure.

[0009] In one feasible implementation, the system further includes a universal joint, which is rotatably connected to the center of the top of the lampshade, and the heat sink is fixedly installed below the universal joint.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This circular skylight lamp head achieves efficient composite light effects and convenient installation through structural innovation. The light source is fixed below the heat sink, and the reflector cup covers the outside of the light source and focuses the light onto the surface of the fog blue diffuser plate to form a stable circular light spot. When the light passes through the fog blue diffuser plate, it is scattered and filtered by blue light, producing a superimposed visual effect of blue sky background and sun spot. At the same time, the annular elastic protrusion and its annular groove (the groove edge is designed with an arc surface) of the snap-fit ​​component allow the edge of the fog blue diffuser plate to be elastically snapped in and hidden inside the lamp cover, achieving seamless fixing and non-destructive disassembly and assembly. The axis of the reflector cup is perpendicularly aligned with the center of the fog blue diffuser plate and the light source is located at the focal position, ensuring that the light spot is uniform and clear. It breaks through the limitations of traditional single light effects, providing rich layers of blue sky and sun composite light effects; the hidden snap-fit ​​eliminates exposed edges, improving the aesthetics and integrity of the lamp; the arc surface structure of the annular groove simplifies the installation process and reduces friction damage; it optimizes light distribution, installation efficiency and appearance, and solves the problems of blurred light effects, complex assembly and exposed seams in traditional designs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 3This utility model provides a technical solution: a circular skylight head, comprising: a lampshade 1, a heat sink 2, a snap-fit ​​assembly, and a reflector 3. The lampshade 1 is circular and has an opening at the bottom. The heat sink 2 is fixed inside the top of the lampshade 1, and a light source 8 is installed below the heat sink 2. A fog blue diffuser 4 covers the bottom opening of the lampshade 1. The snap-fit ​​assembly is disposed between the bottom edge of the lampshade 1 and the fog blue diffuser 4. The reflector 3 is placed outside the light source 8, with the focusing surface of the reflector 3 facing the fog blue diffuser 4, for converging the light from the light source 8 onto the surface of the fog blue diffuser 4 to form a light spot.

[0017] It should be noted that the axially symmetrical structure of the circular lampshade 1 ensures uniform light distribution, and the fixed connection between the heat sink 2 and the top of the lampshade 1 forms an independent heat dissipation space, preventing heat from being conducted downwards and affecting the performance of the diffuser plate. When the fog blue diffuser plate 4 covers the bottom opening, its edges are wrapped by snap-fit ​​components, achieving screwless fixing and concealing seams. The reflector cup 3 reflects the light emitted by the light source 8 to a specific area of ​​the fog blue diffuser plate 4, and the angle control of the focusing surface allows the light to form a circular light spot with a controllable diameter on the surface of the fog blue diffuser plate 4. When the light passes through the fog blue diffuser plate 4, it undergoes scattering and color filtering, and after superimposing with the high-brightness light spot, it produces a composite visual effect of blue sky and sun.

[0018] This device replaces the traditional Rayleigh diffuser with a misty blue diffuser plate 4, superimposing sunlight spots on top of the blue sky effect, breaking through the limitations of single light effects. The snap-fit ​​assembly eliminates mounting hole marks, allowing a smooth transition between the edge of the misty blue diffuser plate 4 and the lampshade 1. The reflector cup 3 is perpendicularly aligned with the misty blue diffuser plate 4, ensuring a stable light spot shape and clear boundaries, overcoming the blurry light effect of traditional diffused light sources. It can simultaneously generate a composite light effect of a blue sky background and sunlight spots, enhancing visual depth; it allows for quick and non-destructive installation and removal of the misty blue diffuser plate 4; it conceals the installation seams of the misty blue diffuser plate 4, maintaining the integrity of the lamp's appearance; and it enhances the expressiveness of light and shadow by controlling the shape of the light spot through directional focusing.

[0019] In some examples, the axis of the reflector cup 3 is further aligned vertically with the center of the blue diffuser plate 4. This vertical alignment, through geometric constraints, defines the relative positions of the reflector cup 3 and the blue diffuser plate 4, ensuring that the light spot generated by the light source 8 always covers the effective area of ​​the blue diffuser plate 4, thus avoiding brightness attenuation in the edge areas.

[0020] In some examples, the light source 8 is further positioned as a point light source 8, located at the focal point of the reflector cup 3. When the point light source 8 is mounted at the focal point of the reflector cup 3, the reflected beam can form a circular spot of uniform diameter on the surface of the fog blue diffuser plate 4, eliminating the bright and dark stripes caused by the positional offset of the traditional light source 8.

[0021] In some examples, the snap-fit ​​assembly further includes: an annular elastic protrusion 5, which extends horizontally along the inner edge of the lower end of the lampshade 1. The annular elastic protrusion 5 has an annular groove 6 recessed inwards from the lampshade 1, and the edge of the fog blue diffuser plate 4 snaps into the annular groove 6. During installation, the fog blue diffuser plate 4 is embedded into the annular groove 6 by its edge. The annular elastic protrusion 5 undergoes elastic deformation under the pressure of the fog blue diffuser plate 4. After the fog blue diffuser plate 4 is fully snapped in, it elastically recovers to form a wrap-around fixation. The annular groove 6 ensures that the fog blue diffuser plate 4 is evenly stressed circumferentially, avoiding local stress concentration that could lead to deformation. The horizontal extension of the annular elastic protrusion 5 completely covers the edge of the fog blue diffuser plate 4 inside the lampshade 1, preventing the process edge from being exposed. This device, through the hidden annular groove 6 and elastic deformation, achieves quick snap-fit ​​while completely covering the edge of the fog blue diffuser plate 4, allowing installation to be completed without additional fasteners.

[0022] The annular elastic protrusion 5 and annular groove 6 enable quick disassembly and installation of the blue fog diffuser plate 4. During installation, simply pressing the blue fog diffuser plate 4 is sufficient to secure it. The annular groove 6 ensures that the blue fog diffuser plate 4 does not shift or fall off under vibration, while the elastic properties of the annular elastic protrusion 5 allow for removal of the blue fog diffuser plate 4 by applying reverse force during disassembly and maintenance. The edges of the blue fog diffuser plate 4 are completely hidden inside the lampshade 1, resulting in no visible clips or edges on the lamp's exterior, achieving a seamless visual effect.

[0023] In some examples, the annular groove 6 has a curved edge. During the installation of the blue diffuser plate 4, it slides into the annular groove 6 along the curved surface for positioning. Simultaneously, the curved structure eliminates the sharp edges formed by traditional right-angled grooves, resulting in a smooth transition between the edge of the blue diffuser plate 4 and the lampshade 1, visually concealing assembly gaps. This also facilitates the installation and removal of the blue diffuser plate 4. The curved structure achieves a smooth edge transition, reducing frictional resistance during assembly and avoiding exposed edges caused by sharp corners. This solves the risk of scratches caused by sharp groove edges during installation of the blue diffuser plate 4, improving assembly smoothness. Furthermore, the smooth transition conceals the seam, improving the overall appearance and aesthetics of the lamp holder.

[0024] In some examples, this further includes a gimbal 7, which is rotatably connected to the top center of the lampshade 1, with the heat sink 2 fixedly installed below the gimbal 7. The gimbal 7 can achieve 360-degree horizontal rotation while supporting pitch angle adjustment. During the adjustment process, the relative position of the light source 8 and the reflector 3 remains unchanged, ensuring that the shape of the light spot is not affected by the angle change.
