Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a moving head lamp with a light source that is easy to disassemble and assemble. Background Art

[0002] Moving head lights usually refer to lamps used to emit various lights on stages and squares. They are also high-tech products that integrate electronics, mechanics, and optics.

[0003] Existing moving head lights usually include a light source and a cooling fan. When in use, the light source emits light to create a stage effect, while the cooling fan generates airflow to blow toward the light source, so that the heat generated by the light source is taken away by the airflow to achieve heat dissipation of the light source. With the increase in large-scale stage performances, more and more moving head lights use high-power light sources to increase the range of the light. However, high-power light sources generate more heat, and it is far from enough to rely solely on cooling fans for heat dissipation, which can easily cause the temperature inside the lamp body to rise rapidly, affecting the service life of the light source and other internal components.

[0004] In order to enhance the heat dissipation effect, a new sealed heat dissipation structure of a rainproof moving head beam lamp disclosed in the existing patent CN112303600A is used to enhance the heat dissipation effect by arranging a fin assembly around the light source that can directly absorb the heat emitted by the light source. However, when adopting this structure, the inventor found that when the light source needs to be replaced, it is necessary to successively remove the lamp housing, the heat dissipation fan, the fin assembly, the heat dissipation fixing plate and the light source mounting substrate, and then remove the light source from the light source mounting substrate for replacement. After the replacement, the above-mentioned removed components must be reinstalled. The whole process is cumbersome, resulting in very low efficiency when disassembling and assembling the light source.

[0005] Therefore, there is an urgent need to design a moving head light that is easy to disassemble and assemble the light source. When replacing the light source, there is no need to remove the fin assembly, the heat dissipation fixing plate and the light source mounting substrate, which effectively simplifies the disassembly and assembly steps, and can quickly disassemble and assemble the light source and the cooling fan, greatly improving the replacement efficiency. The structure is simple, and disassembly and assembly are convenient and quick. Utility Model Content

[0032] When the light source of an existing moving head light needs to be replaced, the lamp housing, cooling fan, fin assembly, cooling fixing plate and light source mounting substrate need to be removed in sequence, and then the light source needs to be removed from the light source mounting substrate for replacement. After the replacement, the removed parts need to be reinstalled. The whole process is cumbersome, resulting in very low efficiency when disassembling and assembling the light source.

[0033] In response to the above problems, an embodiment of the present application provides a moving head light with an easy-to-disassemble and assemble light source. When replacing the light source, there is no need to remove the fin assembly, the heat dissipation fixing plate and the light source mounting substrate, which effectively simplifies the disassembly and assembly steps, and can quickly disassemble and assemble the light source and the cooling fan, greatly improving the replacement efficiency. The structure is simple, and disassembly and assembly are convenient and quick.

[0034] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1-Figure 7 The moving head light with easy disassembly and assembly of the light source of the present application comprises a lamp holder and a lamp body, and the lamp body is rotatably arranged on the lamp holder. The lamp body comprises a lamp housing 1, a heat dissipation component, a heat dissipation component fixing plate 3 and a light source component 4, and the lamp housing 1, the heat dissipation component, the heat dissipation component fixing plate 3 and the light source component 4 are all arranged in the lamp housing 1.

[0036] Specifically, the lamp housing 1 includes a shell body 11 and a back cover 12, the back cover 12 is fixed to the shell body 11 by screws, and the shell body 11 and the back cover 12 are connected to form an accommodating cavity, and the heat dissipation component, the heat dissipation component fixing plate 3 and the light source component 4 are all arranged in the accommodating cavity. Figure 1 As shown, in order to facilitate ventilation and heat dissipation, the back cover 12 is provided with ventilation and heat dissipation holes 121 , and the ventilation and heat dissipation holes 121 are arranged at the edge and center area of ​​the back cover 12 .

[0037] The heat sink fixing plate 3 is disposed between the shell body 11 and the back cover 12, and divides the accommodating inner cavity into an outer cavity and an inner cavity, wherein the outer cavity is the accommodating inner cavity on the side away from the light emitting end. Specifically, the heat sink fixing plate 3 is connected to the shell body 11 and the back cover 12 respectively. Figure 1 As shown, the heat sink fixing plate 3 is connected to the shell body 11 through the first fixing hole 6 , and is connected to the back cover 12 through the second fixing hole 7 .

[0038] The heat dissipation assembly and the light source assembly 4 are arranged on both sides of the heat dissipation component fixing plate 3. Specifically, the light source assembly 4 is arranged on the inner side of the heat dissipation component fixing plate 3, that is, the light source assembly 4 is arranged in the inner cavity, and the light source assembly 4 includes a light source, a lamp cup 41 and a light source mounting plate 42. The light source mounting plate 42 is arranged on the inner side of the heat dissipation component fixing plate 3, the light source is arranged in the lamp cup 41, and the light emission direction of the light source is toward the light output end of the moving head light. Among them, the inner side is a side relatively far away from the rear cover. The lamp cup 41 is connected to the light source mounting plate 42; exemplarily, as Figure 3-Figure 4As shown, in order to facilitate the disassembly and assembly of the lamp cup 41 and the light source, the light source assembly 4 also includes a rotating block 43; the rotating block 43 is relatively arranged around the lamp cup 41 and is rotatably connected to the light source mounting plate 42. Specifically, the rotating block 43 includes a rotating shaft and a block, the rotating shaft is respectively connected to the light source mounting plate 42 and the block, the block is arranged at the top of the rotating shaft, and by rotating the block 43, the bottom end of the block is abutted against the cup wall of the lamp cup 41, so that the lamp cup 41 is fixed on the light source mounting plate 42. When the lamp cup 41 needs to be disassembled, it is only necessary to rotate the rotating block 43 so that the block is away from the lamp cup 41, and the lamp cup 41 can be disassembled from the light source mounting plate 42, which is simple and convenient.

[0039] Furthermore, in order to simplify the disassembly and assembly steps when replacing the light source, the heat sink fixing plate 3 is provided with an opening 31, and the opening 31 is directly opposite to the light source assembly 4 and can accommodate the light source assembly 4. Furthermore, the shape of the opening 31 is circular, and the area of ​​the opening 31 is larger than any cross-sectional area of ​​the lamp cup 41, so that when disassembling the light source, it is only necessary to pass the removed lamp cup 41 through the opening 31 to take the lamp cup 41 from the inner cavity to the outer cavity. By setting the opening 31 to be circular, when the user disassembles the light source, it can effectively prevent the wall of the opening 31 from scratching the user's hand.

[0040] The heat dissipation assembly includes a heat dissipation fan 21 and heat dissipation fins 22. In order to enhance the heat dissipation effect and reduce the space occupied by the heat dissipation fan 21, the heat dissipation fins 22 are arranged on the outside of the opening 31, and the heat dissipation fins 22 are arranged around the opening 31. For example, a part of the heat dissipation fins 22 are arranged in the inner cavity and located around the light source to absorb the heat generated by the light source, and a part of the heat dissipation fins 22 are arranged around the outside of the opening 31, that is, a part of the heat dissipation fins 22 are arranged around the heat dissipation fan 21 to receive the heat transferred from the heat dissipation fins 22 located in the inner cavity. By arranging the heat dissipation fan 21 on the outside of the opening 31 and arranging the heat dissipation fins 22 located in the outer cavity along the periphery of the opening 31, the layout of the heat dissipation assembly is compact.

[0041] In order to facilitate the installation of the cooling fan 21, the cooling assembly further includes a fan mounting bracket 23. Figure 1As shown, the fan mounting bracket 23 is symmetrically arranged on the heat sink fixing plate 3, and one end of the fan mounting bracket 23 is located outside the heat sink fins 22. Screw holes 24 are arranged at both ends of the fan mounting bracket 23, and threaded through holes 211 matching the screw holes 24 are arranged at the four corners of the heat dissipation fan 21. Bolt assemblies pass through the threaded through holes 211 and the screw holes 24, thereby fixing the fan on the fan mounting bracket 23.

[0042] In another preferred embodiment, since the cooling fan 21 needs to be disassembled and assembled when replacing the light source, in order to improve the efficiency of disassembling and assembling the cooling fan 21, as shown in FIG. Figure 6-Figure 7 As shown, the fan mounting bracket 23 is provided with a slide rail 25, and the extension direction of the slide rail 25 is consistent with the length direction of the fan mounting bracket 23. The heat dissipation fan 21 is provided with a slider adapted to the slide rail 25, and the slider can slide in the slide rail 25. When the heat dissipation fan 21 is installed on the slide rail 25, the two ends of the heat dissipation fan 21 are flush with the two ends of the slide rail 25. In order to fix the heat dissipation fan 21 on the slide rail 25, the two ends of the slide rail 25 are provided with fixing blocks 26, and the fixing blocks 26 are used to prevent the heat dissipation fan 21 from sliding off the slide rail 25. Specifically, the fixing blocks 26 are rotatably arranged at the two ends of the slide rail 25, and the rotation angle of the fixing blocks 26 is 180 degrees. When the cooling fan 21 needs to be fixed, the slider on the cooling fan 21 is fixed to the slide rail 25, and then the fixing block 26 is rotated so that the fixing block 26 abuts against both ends of the cooling fan 21, thereby fixing the cooling fan 21 to the slide rail 25 to prevent the cooling fan 21 from sliding on the slide rail 25. When the cooling fan 21 needs to be removed, the cooling fan 21 can be removed from the slide rail 25 by simply rotating the fixing block 26 and moving the fixing block 26 away from the cooling fan 21.

[0043] Furthermore, in order to prevent the heat of the light source from being directly transferred to the outer cavity through the opening 31 and damaging the power line and other components in the outer cavity, the moving head light for easy disassembly of the light source further includes a heat insulation board 5 adapted to the opening 31, and the heat insulation board 5 is arranged at the opening 31 and connected to the heat sink fixing plate 3. Specifically, as Figure 1-Figure 2 As shown, the heat sink fixture plate also includes a plurality of connecting protrusions 32; the plurality of connecting protrusions 32 are distributed along the circumferential direction of the opening 31; a connecting through hole 33 is provided on the connecting protrusion 32, and the connecting through hole 33 is adapted to the mounting through hole 51 on the heat insulation board 5, and the heat insulation board 5 is fixed at the opening 31 by screws passing through the mounting through hole 51 and the connecting through hole 33.

[0044] Furthermore, in order to increase the heat insulation effect, the moving head light with easy disassembly and assembly of the light source further includes a sealing ring, which is arranged between the heat insulation plate 5 and the heat sink fixing plate 3. Specifically, an annular groove is arranged on the outer periphery of the heat insulation plate, and the sealing ring is placed in the annular groove, and the heat insulation plate 5 is fixed at the opening 31 by screws, thereby further improving the sealing performance.

[0045] When the light source needs to be replaced, the screws on the back cover 12 are simply removed to separate the back cover 12 from the shell body 11 to expose the cooling fan 21 and the cooling fins 22, and the fixing block 26 is rotated to make the fixing block 26 move away from the cooling fan 21, and then the cooling fan 21 is removed from the slide rail 25, and then the screws on the heat insulation board 5 are removed to remove the heat insulation board 5 to expose the opening 31, and the rotating stopper 43 is rotated through the opening 31 to separate the stopper from the lamp cup 41, thereby removing the lamp cup 41 and the light source, so as to facilitate the replacement of the light source. When the light source is replaced, the above steps are repeated in reverse, which will not be described in detail here.

[0046] In the present embodiment, the moving head light provided by the present application is easy to disassemble and assemble the light source. An opening is provided on the heat sink fixing plate and a rotating block is provided around the lamp cup, so that the lamp cup and the light source located in the inner cavity can be quickly taken out without removing the heat sink fins, the heat sink fixing plate and the light source mounting plate. The heat dissipation fan is arranged at the opening and the heat dissipation fins are arranged around the opening, so that the space occupied by the heat dissipation component is reduced through a compact layout. A slide rail is provided on the fan mounting bracket, so that the disassembly and assembly of the heat dissipation fan is faster and more convenient. Compared with the existing moving head lights which mostly use screw fixing, the moving head light provided by the present application does not need to remove the fin assembly, the heat sink fixing plate and the light source mounting substrate when replacing the light source, which effectively simplifies the disassembly and assembly steps, and can quickly disassemble and assemble the light source and the heat dissipation fan, greatly improving the replacement efficiency. The structure is simple and the disassembly and assembly are convenient and quick.

[0047] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0048] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
