[0002] Existing display lights used in indoor venues such as theaters and exhibition centers suffer from the following problems due to structural limitations:

[0003] 1. The focusing mechanism uses a complex structure consisting of a slide bar and a focusing frame, which not only has high cost and a large number of parts, making it difficult to process and assemble, but also occupies internal space of the lamp, resulting in an increase in the size of the lamp.

[0004] 2. The design of installing the heat sink inside the casing increases the number of steps and parts required for installing the heat sink and the casing, resulting in poor integration and poor active heat dissipation due to the limited space inside the casing.

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0041] like Figure 1-4 As shown, a dimmable display light includes a light source assembly 1, a housing assembly 2, and a lens assembly, characterized in that:

[0042] The outer casing assembly 2 includes an outer casing 21, which is a hollow cylindrical structure. Heat sinks 22 are provided at the non-end positions inside the outer casing 21, and a lens assembly is provided at one end.

[0043] The radiator 22 is integrally formed with the outer shell 21. A through first heat dissipation channel 10 is opened in the middle of the radiator 22, and circumferentially distributed heat dissipation fins 223 are provided on the outer perimeter.

[0044] The heat dissipation fins 223 are connected to the inner wall of the outer shell 21, and a second heat dissipation channel 20 is formed between adjacent heat dissipation fins 223;

[0045] A heat dissipation port 211 is provided on the outer shell 21 at the connection with the heat dissipation fins 223, and the second heat dissipation channel 20 communicates with the outside through the heat dissipation port 211;

[0046] The light source assembly 1 is located between the heat sink 22 and the lens assembly. The light source assembly 1 includes a light source body 11 and a heat sink copper block 12.

[0047] The heat dissipation copper block 12 is embedded in the first heat dissipation channel 10, and the surface of the heat dissipation copper block 12 is connected to the light source body 11.

[0048] A focusing component 3 is provided between the lens assembly and the housing 21.

[0049] In this embodiment, a structural design is adopted in which the outer shell 21 and the heat sink 22 are integrally formed, eliminating the need for installation of the heat sink 22 and the outer shell 21 and the parts, reducing costs and improving assembly efficiency.

[0050] In this embodiment, the heat generated by the light source component 1 is directly transferred to the heat sink 22 or the first heat dissipation channel 10 through the heat dissipation copper block 12; the heat transferred to the heat sink 22 is transferred to the outer casing 21 through the heat dissipation fins 223 or to the outside through the heat dissipation port 211, and the heat entering the first heat dissipation channel 10 is directly transferred to the outside of the outer casing 21; thus, through the integrated multi-stage heat dissipation structure, efficient active heat dissipation is achieved, and the structure is simple.

[0051] Furthermore, such as Figure 1 , 2 As shown, in order to quickly transfer the heat from the heat sink 223 to the outside and improve the heat dissipation performance, the heat dissipation port 211 is a 360-degree annular groove.

[0052] Furthermore, such as Figure 2 , 3 As shown in Figures 4 and 5, the focusing assembly 3 includes a connecting cylinder 31, a focusing cylinder 32, and a connecting plate 33.

[0053] The connecting cylinder 31 is disposed inside the outer shell 21. One end of the connecting cylinder 31 near the light source is threadedly connected to the outer shell 21, and the other end is an adjustment end extending to the outside of the outer shell 21.

[0054] The connecting cylinder 31 has at least two through arc-shaped track grooves 311 on its circumferential side, and the connecting cylinder 31 is connected to the heat dissipation copper block 12 through the connecting plate 33.

[0055] The focusing cylinder 32 is rotatably disposed between the outer shell 21 and the connecting cylinder 31. A through linear guide groove 321 is provided on the focusing cylinder 32, and the linear guide groove 321 and the arc-shaped track groove 311 are configured in a one-to-one correspondence.

[0056] The lens assembly includes a lens bracket 4 that is movably disposed within the connecting tube 31;

[0057] A connecting post 6 is provided in the arc-shaped track groove 311. One end of the connecting post 6 extends into the straight guide groove 321, and the other end is fixedly connected to the lens bracket 4.

[0058] In this example, the focusing structure, which uses an arc-shaped track groove 311 and a connecting column 6, can be manually rotated to simplify the structure, reduce costs and processing and assembly difficulty, reduce the space occupied inside the lamp, achieve miniaturization, and ensure stable and reliable focusing.

[0059] Furthermore, such as Figure 2 , 3As shown in Figure 4, the lens bracket 4 has a first light-transmitting hole 41, and a lens (not shown in the figure) is disposed inside the first light-transmitting hole 41.

[0060] Furthermore, such as Figure 2 , 3 As shown in Figure 4, in order to reduce axial space occupation and improve light efficiency, the lens is a Fresnel lens.

[0061] Furthermore, such as Figure 2 , 3 As shown in Figure 4, in order to precisely limit the area of ​​light illumination, a light control component 7 is provided at one end of the connecting cylinder 31 located outside the outer shell 21, and the light control component 7 is rotatably snapped to the connecting cylinder 31.

[0062] Furthermore, such as Figure 1 , 2 As shown, the light control component 7 includes a connecting seat 71 that is rotatably snapped to the connecting cylinder 31, and an angle-adjustable light-blocking plate 72 is provided around the other end of the connecting seat 71.

[0063] In this embodiment, by adjusting the opening angle of the four light-blocking plates 72, the area illuminated by the light can be precisely limited, preventing light from being projected onto stage areas that do not need to be illuminated. In addition, by adjusting the degree of closure of the light-blocking plates 72, the hardness and sharpness of the beam edge can be changed. When fully closed, the light edge is sharp, forming a clear distinction between light and shadow; when partially open, the edge is softer.

[0064] In this embodiment, in order to limit the rotation of the connecting seat 71 relative to the connecting cylinder 31, the light control component 7 also includes a locking bolt.

[0065] Furthermore, such as Figure 1 , 2 As shown, in order to meet the installation requirements of specific scenarios, the housing assembly 2 also includes a boom 23 connected to the housing body 21.

[0066] In this embodiment, the boom 23 is rotatably connected to the housing 21, and the angle of the lamp can be adjusted as needed.

[0067] Furthermore, such as Figure 2 As shown, in order to improve color resolution and achieve continuous dimming, a DMX512 controller 8 electrically connected to the light source is provided at one end of the housing 21 away from the lens assembly.

[0068] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
