[0056] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the invention.

[0057] like Figures 1-8 As shown, this application provides a reflective lighting fixture, comprising: a combined light panel, wherein several isosceles trapezoidal sub-light panels are connected side-by-side to form a truncated pyramid shape, wherein each sub-light panel includes a panel body and several light-emitting units, the light-emitting units being evenly distributed on one side surface of the panel body; a reflective panel, the reflective surface of which is composed of several annular curved surfaces with different curvatures; the center of the reflective panel is hollowed out, the shape of which is the same as the top cross-section of the combined light panel; the top cross-section of the combined light panel is aligned with the shape of the hollowed-out section and is directly or indirectly fixed to the reflective panel; a housing, the housing including a light-emitting cover and a rear shell, wherein the combined light panel and the reflective panel are accommodated in the internal cavity formed by the light-emitting cover and the rear shell, wherein the bottom of the combined light panel abuts against the light-emitting cover, and the non-reflective surface of the reflective panel is fixedly connected to the rear shell; the light emitted by the light-emitting units is reflected by the reflective surface of the reflective panel and then emitted from the light-emitting cover.

[0058] It should be understood that the truncated pyramid refers to the portion between the base and the cross-section of a pyramid after it has been truncated by a plane parallel to its base. The base and cross-section of the original pyramid are called the lower base and upper base of the truncated pyramid, respectively, and the remaining faces are called the lateral faces of the truncated pyramid. The common edge of adjacent lateral faces is called the lateral edge of the truncated pyramid.

[0059] The side of the pyramid is inclined, unlike the vertical side of the prism. In the design of the multi-pyramid, since the angle of each sub-light panel can be adjusted, it can ensure that an angle less than 90 degrees is formed between each light panel and the reflection panel. Such a design allows light to better illuminate the reflection panel and be reflected out through the curved surface of the reflection panel. This is because the curvature of the reflection panel can make the reflection direction of the light towards the area that needs to be illuminated, ensuring that the light is uniformly reflected. The design of the multi-pyramid allows the light to be reflected in a certain direction, especially in the area behind the light cover, which can effectively adjust the reflection path of the light to ensure that the light emitted from the light cover is more uniform and concentrated.

[0060] It should be understood that the truncated multi-pyramid in the present application can also be replaced by a multi-pyramid (non-truncated). However, since the complete multi-pyramid is not truncated, the sharp corner area at the top cannot effectively accommodate the LED light emitting unit, because the space in the sharp corner area is limited. This not only makes the space utilization at the top low, but also placing the LED light emitting unit in this area can cause uneven illumination. Therefore, the truncated design can remove the top sharp corner part, optimize the available space, and improve the space utilization of the entire light panel. Due to the limitation of the space at the top of the complete multi-pyramid, the use of the truncated design can reduce the overall thickness of the lamp, making it more compact, facilitating the integration of the LED light emitting unit, and helping to improve the uniform distribution of the light source. The truncated design not only improves the utilization efficiency of the space, but also makes the structure more stable, and can reduce complexity and manufacturing cost in production, especially when producing large-scale LED lamps, this optimized design is more economical and efficient. Therefore, preferably, the shape of the combined light panel is designed as a truncated multi-pyramid.

[0061] In order to avoid direct exposure of the light source of the LED lamp bead, the light-emitting surface of the lamp bead is designed to face away from the light-emitting surface (light-emitting cover) of the lamp, so that the light-emitting unit on the combined lamp panel will not directly irradiate to the outside, avoiding too concentrated light spot or strong direct light, reducing the appearance of LED light source particles, avoiding direct glare, improving the light quality of the lamp, making the emitted light more soft and comfortable, and not causing visual discomfort. The reflection panel is an important structure for realizing the design of the light-emitting surface facing away from the light-emitting surface and emitting uniform and soft light. The reflection panel reflects through different paragraphs of the inner curved surface, and the curvature of each paragraph is different. The curved surface of the reflection panel will reflect the light to different degrees for different lamp beads. The curvature of the reflection cavity can be adjusted according to the specific position and light-emitting angle of each lamp bead to make the reflection of light more uniform. Especially by adjusting the curvature in sections, the curvature design of different sections can ensure that the light of the point light source is uniformly dispersed into a surface light source after reflection. Through this reflection design, the light is no longer strong direct light, but is dispersed to form a soft surface light source. The surface light source can effectively avoid strong light spots, reduce shadows, make the light distribution more uniform, and the lighting effect more comfortable.

[0062] Strictly speaking, under this design structure, the light generated by the light-emitting unit on the combined lamp panel is actually divided into two parts. Most of the light irradiates onto the reflection panel, because the unique curvature and texture of the reflection panel produce a large amount of diffuse reflection and then transmits through the light-emitting surface from various directions. The result is that light transmits through the entire light-emitting surface, the light-emitting surface emits light uniformly, and the light is soft. A small part of the light is emitted from the light-emitting surface at a small angle. The small-angle light ensures the lighting intensity while avoiding the glare problem of direct light, so that the overall lamp still has good light softness and uniformity effect.

[0063] The center of the reflection panel is hollow, and the shape of the hollow is the same as the top section of the combined lamp panel. After the top section of the combined lamp panel is aligned with the shape of the hollow, it is directly or indirectly fixed on the reflection panel. The hollow design of the reflection panel matches the top section of the truncated polygonal pyramid of the combined lamp panel, and the hollow structure provides better air flow space, which helps heat dissipation. That is, the heat generated by the light-emitting unit can be dissipated through the hollow area, helping the lamp to maintain a low temperature, reducing the effect of temperature on the LED light-emitting unit, and prolonging the service life of the lamp.

[0064] In an embodiment of the present application, the three isosceles trapezoidal sub-lamp panels are enclosed in the form of a truncated triangular pyramid according to the side connection.

[0065] The truncated triangular pyramid design is more geometrically simple than the truncated polygonal pyramid. The triangular pyramid has only three sides, which makes it easier to control and optimize the reflection and emission direction of light compared to a polygonal shape. In this design, the propagation and reflection of light are more predictable and adjustable. The truncated triangular pyramid structure enclosed by three isosceles trapezoidal sub-lamp panels makes it easier to guide the reflection of light to the designated area, avoiding excessive scattering of light, and ensuring that the light is emitted uniformly and concentrated towards the light cover. Since there are only three sides, the reflection path of the light is relatively easier to design and optimize, ensuring that the light is dispersed from the point source to the area light source, avoiding light spots, and providing a more uniform lighting effect. Compared with the truncated polygonal pyramid, the truncated triangular pyramid has fewer sides (only three sides), making it more stable in structure. Such a structure is also more robust during design and manufacturing, avoiding instability that may occur due to excessive panel connections. Due to its simple geometric structure, the truncated triangular pyramid is easier to assemble and install than the truncated polygonal pyramid. The docking and installation between multiple sub-lamp panels are relatively easy, reducing the difficulty of installation and saving debugging and installation time.

[0066] In an embodiment of the present application, the reflective surface has a concave-convex texture that can cause the incident light to be diffusely reflected.

[0067] When light strikes an object with an irregular surface, such as a concave-convex texture, the light is reflected in multiple directions rather than at a specific angle, which is diffuse reflection. The uneven texture on the reflective surface acts as an irregularity, allowing the incident light to be scattered multiple times on the surface, making the reflection of light more uniform and not concentrated in a certain point or area, thereby reducing the concentration and glare of light and improving the overall lighting effect. The concave-convex texture on the reflective surface further promotes diffuse reflection. These subtle textures will cause the light to scatter multiple times during reflection, thereby uniformizing the distribution of light and making the lighting effect more soft and delicate. The concave-convex texture not only improves the uniformity of light but also reduces the direct intensity of light, making it more suitable for environmental lighting needs. And this texture design helps to ensure that the light covers a larger range, forming a soft area light source.

[0068] The concave-convex texture structure includes, but is not limited to, a frosted texture, an orange peel texture, a micro-porous structure, a wire-drawing texture, a micro-crystal texture, a honeycomb texture, a bevel texture, a metal micro-texture, and a micro-spherical structure, etc. Among them, the frosted texture refers to treating the surface of a material with sand or other abrasives to produce a fine rough texture. These rough surfaces cause multiple reflections of light when reflected, resulting in light scattering, thereby producing diffuse reflection. The orange peel texture is similar to the concave-convex feeling of the surface of an orange. It causes light scattering through large-scale irregular undulations. Unlike the frosted texture, the orange peel texture has larger irregularities, forming a more noticeable optical effect. The micro-porous structure is produced by making a large number of tiny holes on the reflecting surface. These holes can be regular or irregular, causing incident light to be refracted and reflected multiple times through the holes, thereby scattering the light. The wire-drawing texture is formed by a series of fine lines or lines on the surface. When light hits these lines, it produces tiny reflections and refractions, thereby achieving diffuse reflection of light. The micro-crystal texture is formed by fine micro-crystal or micro-structure particles on the surface, causing multiple refractions and reflections of light when it contacts the surface. The honeycomb texture is composed of tiny concave pits in the shape of a honeycomb. These small holes change the propagation path of light through reflection and refraction. The bevel texture is to change the incident angle of light by setting a certain angle of bevel or inclined lines, so that light is reflected in different directions, thereby achieving diffuse reflection. The metal micro-texture refers to the fine concave-convex structure on the surface of the metal, such as the microstructure produced by etching or milling techniques, to control the path of light reflection. The micro-spherical structure creates tiny spherical particles on the surface. These particles, like tiny bumps, can reflect light in multiple directions.

[0069] In an embodiment of the present application, a heat sink is further included, the heat sink includes a heat sink main body, the heat sink main body includes an integrally formed tapered portion and a circular base plate; the tapered portion is in the shape of a truncated polygonal pyramid same as the combined lamp panel; the bottom surface of the tapered portion is connected to one side of the circular base plate, wherein the inside of the tapered portion is hollow and the bottom surface is open, and the area of the circular base plate coinciding with the bottom surface of the tapered portion is empty; the combined lamp panel is fixed on the heat sink, wherein the plate body of the sub-lamp panel is fixedly attached to the outside of the corresponding tapered portion; the other side of the circular base plate abuts against the light exit cover.

[0070] It should be understood that when the technical solution does not include a heat sink, the combined lamp panel can be fixed directly with the reflecting panel by means of adhesive or the like. Among them, the combined lamp panel can be adhered as a whole with the reflecting panel, or divided into several sub-lamp panels and adhered with the reflecting panel respectively. When the technical solution includes a heat sink, the combined lamp panel can be indirectly fixed with the reflecting panel by fixing the sub-lamp panel with the heat sink (the heat sink is then fixed with the reflecting panel).

[0071] Preferably, the adapter plate is in a triangular ring structure, and a plurality of connecting through holes are arranged on the adapter plate, and the center of the reflective panel and the top surface of the tapered portion are provided with corresponding connecting through holes, and when the combined lamp panel is fixed to the heat sink, the corresponding connecting through holes of the heat sink, the reflective panel and the adapter plate are connected by screws to fix them.

[0072] It should be understood that the overall structure of the plate body of the combined lamp panel and the heat sink can be made of ceramic material, which has good thermal conductivity, especially some specific types of ceramics such as aluminum-based ceramics, aluminum nitride ceramics, etc. can effectively conduct the heat generated by the chip to the heat sink, thereby avoiding the influence of excessive temperature on the performance of the LED lamp beads and prolonging the service life of the lamp.

[0073] In an embodiment of the present application, the part of the light exit cover abutting against the circular substrate is hollowed out. Since the circular substrate of the heat sink is arranged to abut against the light exit cover on the side provided with the heat dissipation fins, and the abutting part of the light exit cover is arranged in a hollow structure, heat can be dissipated from the fins and further dissipated to the external air through the hollow structure, thereby improving the heat dissipation effect.

[0074] In an embodiment of the present application, the heat sink further comprises heat dissipation fins.

[0075] In an embodiment of the present application, the heat dissipation fins are arranged in a sunflower shape on the other side of the circular substrate and the inner side surface of the tapered portion.

[0076] It should be understood that the sunflower-shaped fin arrangement can maximize the surface area in contact with the air by its radial structure and distribution, thereby improving the heat conduction efficiency from the surface of the heat sink to the surrounding air. Moreover, such an arrangement can provide more space for air flow, facilitating the inflow of cold air and the removal of heat. The edges of each fin and the gaps between other fins work together to allow air to flow between the fins, forming good natural convection. Moreover, the sunflower-shaped arrangement not only effectively increases the heat dissipation surface, but also provides sufficient heat dissipation area in a relatively compact space. This is particularly important for some lamp designs with limited volume, which can ensure good heat dissipation while saving internal space.

[0077] In an embodiment of the present application, a plurality of heat dissipation through holes with different shapes are arranged on the rear shell.

[0078] The heat dissipation through hole is an important design for providing an air flow passage for the heat dissipation system. By providing a plurality of through holes on the rear shell, the flow of hot air can be promoted. Heat is conducted from the combined lamp panel, heat sink and other areas inside the lamp to the external air, and the through holes help air flow and accelerate heat dissipation.

[0079] In an embodiment of the present application, a cold shoe is further included, one side of the cold shoe being fixed to the shell.

[0080] The cold shoe is a standardized equipment mounting interface, which is usually used to mount accessories (such as flash, microphone, camera, etc.) on lighting equipment or other photographic equipment. In the lamp, the cold shoe is used to connect other external accessories, has the characteristics of modularity, and is convenient for users to adjust and expand the functions of the lamp as needed.

[0081] As shown in Figures 9-11 The lamp of the present application further includes structure modules such as a driving board, a control board, a key and a lithium battery, the control board is used to control the switching and brightness and color temperature adjustment of the lamp, the driving board is used to drive the control board and the LED light emitting unit, the key is convenient for manual pressing to select the corresponding function of the lamp, and the lithium battery stores and provides power for the lamp.

[0082] To reduce the volume of the lamp while setting the lithium battery lamp structure inside the lamp, a U-shaped groove for avoiding the lithium battery structure can be formed on the non-reflective surface of the reflective panel.

[0083] As described above, the present application has the following beneficial effects:

[0084] The reflective lamp of the present application comprises: a combined lamp panel, a plurality of isosceles trapezoidal sub-lamp panels are enclosed in a truncated multi-prism shape in a side-by-side manner, wherein the sub-lamp panel comprises a panel body and a plurality of light emitting units, and the light emitting units are uniformly distributed on one side surface of the panel body; a reflective panel, the reflective surface of the reflective panel is composed of a plurality of annular curved surfaces with different curvatures; the center of the reflective panel is hollow, and the shape of the hollow is the same as the top cross section of the combined lamp panel; after the top cross section of the combined lamp panel is aligned with the shape of the hollow, it is directly or indirectly fixed on the reflective panel. A shell, the shell comprises a light exit cover and a rear shell, the combined lamp panel and the reflective panel are contained in the internal cavity formed by the light exit cover and the rear shell, wherein the bottom of the combined lamp panel abuts against the light exit cover, and the non-reflective surface of the reflective panel is fixedly connected with the rear shell; the light emitted by the light emitting units is reflected by the reflective surface of the reflective panel and then emitted from the light exit cover.

[0085] In summary, the present application effectively overcomes the shortcomings of the prior art and has high industrial utilization value.

Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
