Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and particularly to a waterproof stage lighting fixture. Background Art

[0002] Stage lighting fixtures generally need to be used outdoors. They have high power, long working hours, and also need to cope with the influence of rainy days. Therefore, stage lighting fixtures need to meet the performance requirements of heat dissipation and waterproofing. Currently, most of the outer shells of stage lighting fixtures on the market are designed as metal shells, and multiple heat dissipation ribs are designed on the metal shells. This can not only increase the heat dissipation area but also add air guide plates outside the ribs to form a heat dissipation air channel, improving the heat dissipation efficiency. However, the problem is that more metal material is used for the metal shell, and the outer wall is relatively thick, making the lamp body appear thick and heavy.

[0003] In addition, stage lighting fixtures also need to be maintained frequently, and their shells need to be easily assembled and disassembled to expose the internal components. To meet the requirements of both sealing performance and dismountability, current stage lighting fixtures generally use fasteners such as screws to connect the various parts of the shell together. But this will cause the screws to be exposed outside the shell, which not only affects the aesthetic appearance but also makes the screws prone to corrosion when exposed for a long time, thus affecting the fastening performance. Summary of the Invention

[0004] An object of this application is to at least solve one of the technical problems existing in the prior art, and provide a waterproof stage lighting fixture that is easy to assemble and disassemble and can hide the fastening screws while meeting the sealing performance and heat dissipation performance.

[0030] Stage lights generally need to be used outdoors. They have high power, long working hours, and also need to cope with the influence of rainy days. Therefore, stage lights need to meet the performance requirements of heat dissipation and waterproofing. For the stage lights on the market at present, most of their outer shells are designed as metal shells, and multiple heat dissipation ribs are designed on the metal shells, which can not only increase the heat dissipation area, but also add air guide plates outside the ribs to form heat dissipation air grooves to improve the heat dissipation efficiency. However, the problem brought is that the metal shell uses a lot of materials and the outer wall is relatively thick, so that the lamp body appears thick and heavy.

[0031] In addition, stage lights also need to be maintained frequently, and their shells need to be easily installed and disassembled to expose the internal components. In order to meet the requirements of both sealing performance and detachable performance at the same time, the current stage lights generally use fasteners such as screws to connect the various parts of the shell together. However, this will cause the screws to be exposed outside the shell, which not only affects the aesthetic appearance, but also the screws are easily corroded when exposed outside for a long time, thus affecting the fastening performance.

[0032] In view of this, the present application proposes a waterproof stage light, which uses the middle frame 210 as the core rotating component, and both the upper cover 310 and the lower cover 410 are connected to the middle frame 210, and no heat dissipation ribs are provided on the surface of the light, so that the surface of the light is smooth and has a better-looking appearance.

[0033] Refer to Figure 1 , the waterproof stage light in the embodiment of the present application includes a rotating arm cross beam 100, a middle cover assembly 200, an upper cover assembly 300 and a lower cover assembly 400. Among them, the lamp body formed by combining the middle cover assembly 200, the upper cover assembly 300 and the lower cover assembly 400 can rotate around the rotating arm cross beam 100 to change its pitch angle. The middle cover assembly 200 is used to connect with the rotating arm cross beam 100, and the upper cover assembly 300 and the lower cover assembly 400 jointly form the lamp body with the middle cover assembly 200.

[0034] Specifically, rotating arms 110 extend outwardly from both sides of the rotating arm crossbeam 100. The lamp body is hinged to the rotating arm crossbeam 100 through the rotating arms 110, enabling the lamp body to flip around the hinge axis. The rotating arm crossbeam 100 is rotatably connected to the base 800, and its rotation axis is perpendicular to the ground, for driving the lamp body to rotate on the horizontal plane.

[0035] Referring to Figure 2 , the middle cover assembly 200 includes a middle frame 210. Referring to Figure 3 , extension members 211 are provided on opposite sides of the middle frame 210. The extension members 211 are used for rotatably connecting to the rotating arms 110, achieving the connection relationship between the middle cover assembly 200 and the rotating arm crossbeam 100. The middle frame 210 transitions from the first surface to the second surface along its thickness direction. In this embodiment, the thickness direction specifically refers to Figure 4 the up and down direction in the cross-sectional view of this waterproof stage lamp. It should be noted that the middle frame 210 is provided with a first mounting hole 212 and a second mounting hole 213 that penetrate through the first surface and the second surface, respectively, for connecting the upper cover assembly 300 and the lower cover assembly 400.

[0036] Furthermore, in order to improve the fitting sealing performance of the upper cover assembly 300, the lower cover assembly 400, and the middle cover assembly 200, the middle cover assembly 200 further includes a first sealing strip 220 and a second sealing strip 230. The first sealing strip 220 is adhered to the first surface, and the second sealing strip 230 is adhered to the second surface.

[0037] The upper cover assembly 300 includes an upper cover 310 and upper cover fastening screws 320. The upper cover 310 is barrel-shaped and has a smooth surface. Compared with traditional lamps that add heat dissipation ribs on the outer shell, its appearance is more concise. In this embodiment, the first mounting hole 212 is a through hole. The upper cover fastening screws 320 pass through the first mounting hole 212 of the middle frame 210 and are threadedly connected to the upper cover 310. The end face of the upper cover 310 is adhered to the first sealing strip 220. Thus, by tightening the upper cover fastening screws 320, the upper cover 310 is locked to the middle frame 210, and the gap between the upper cover 310 and the middle frame 210 is filled by the first sealing strip 220 to improve the sealing performance.

[0038] The lower cover assembly 400 includes a lower cover 410, lower cover fastening screws 420, and a heat dissipation grille 430. The lower cover 410 is provided with a ventilation window 411 for installing the heat dissipation grille 430. It should be noted that a guiding hole 412 penetrating through to the end face of the lower cover 410 is provided on the inner wall of the ventilation window 411. The second mounting hole 213 is a threaded hole. The lower cover fastening screws 420 pass through the guiding hole 412 and are threadedly connected to the second mounting hole 213 of the middle frame 210. The end face of the lower cover 410 is adhered to the second sealing strip 230, so that the lower cover 410 is locked to the middle frame 210 by tightening the lower cover fastening screws 420, and the gap between the lower cover 410 and the middle frame 210 is filled by the second sealing strip 230 to improve the sealing performance. The heat dissipation grille 430 is installed on the ventilation window 411. On the one hand, it can reduce the probability of external garbage or dust entering the waterproof stage lamp, and on the other hand, the heat dissipation grille 430 can cover the guiding hole 412 to play a role in hiding the lower cover fastening screws 420.

[0039] Furthermore, the volume of the upper cover 310 accounts for at least half of the total volume of the upper cover 310, the middle frame 210, and the lower cover 410, making the appearance of the lamp housing more integrated and more beautiful.

[0040] Furthermore, a first sealing groove 214 for accommodating the first sealing strip 220 is provided on the first surface of the middle frame 210, and a second sealing groove 215 for accommodating the second sealing strip 230 is provided on the second surface of the middle frame 210, so that the first sealing strip 220 and the second sealing strip 230 can be fixed on the middle frame 210.

[0041] Furthermore, the extension member 211 extends along the thickness direction of the middle frame 210, and a notch for adapting to the shape of the extension member 211 is provided on the end face of the upper cover 310. The first sealing groove 214 extends to the top of the extension member 211, and the extension member 211 is inserted into the notch when the upper cover 310 and the middle frame 210 are assembled.

[0042] Regarding the specific shape of the extension member 211, it can be set as a rectangular plate, a triangular plate, a semi-circular plate, or a semi-elliptical plate, etc. The shape of the notch is adapted to the specific shape of the extension member 211. In this embodiment, the extension member 211 is specifically in the shape of a triangular plate with rounded corners at its ends.

[0043] Furthermore, a retaining strip 216 extends from the second surface of the middle frame 210. The retaining strip 216 is arranged around the second sealing groove 215. It is used to block the splicing gap between the lower cover 410 and the middle frame 210, so as to further improve the sealing performance at the joint, and can also guide the assembly of the lower cover 410 to the middle frame 210.

[0044] The assembly process of the lamp body is as follows: After fixing the first sealing strip 220 and the second sealing strip 230 on the middle frame 210, the upper cover 310 is assembled to the first surface of the middle frame 210. The upper cover fastening screw 320 passes through the second surface of the middle frame 210 and exits from the first surface, and is threadedly connected and locked with the threaded hole on the upper cover 310. Then, the lower cover 410 is assembled to the second surface of the middle frame 210 to hide the upper cover fastening screw 320. The lower cover fastening screw 420 passes through the guiding hole 412 at the air vent window 411 of the lower cover 410 and exits from the end face of the lower cover 410, and is threadedly connected and locked with the second mounting hole 213 of the middle frame 210. Finally, the heat dissipation grille 430 is installed on the air vent window 411 to hide the lower cover fastening screw 420. When disassembly is required, it is carried out in the reverse order of the above installation steps, which will not be elaborated here.

[0045] This waterproof stage lamp also includes a heat dissipation assembly 500. Referring to Figure 4 , the heat dissipation assembly 500 includes a fan 510 and a heat exchanger 520, and the heat exchanger 520 is connected to the middle frame 210. Among them, the fan 510 is used to drive external cold air to enter and contact the heat exchanger 520. After the heat exchanger 520 receives the cold quantity of the cold air, it transfers the cold quantity to the inside of this waterproof stage lamp to achieve the cooling of internal components.

[0046] Furthermore, in this waterproof stage lamp, the number of air vent windows 411 is two and they are symmetrically arranged on both sides of the lower cover 410 to realize the air circulation.

[0047] Furthermore, the upper cover assembly 300 also includes a waterproof light-emitting lens 330, a lens sealing ring 340, and a bolt protective cover 350. The waterproof light-emitting lens 330 is connected to the end of the upper cover 310. The lens sealing ring 340 is installed between the waterproof light-emitting lens 330 and the upper cover 310 to fill the gap between the two. The bolt protective cover 350 is annular and is detachably connected to the upper cover 310, and it is used to shield the installation bolts of the waterproof light-emitting lens 330.

[0048] Furthermore, this waterproof stage lamp also includes a focusing assembly 600 and a pattern assembly 700, and the focusing assembly 600 and the pattern assembly 700 are connected to the middle frame 210. Among them, the focusing assembly 600 is used to adjust the focusing focal length, and the pattern assembly 700 is used to change the shape or color of the projected pattern. Both the focusing assembly 600 and the pattern assembly 700 are detachably connected to the middle frame 210, so that after the upper cover 310 is disassembled, the focusing assembly 600 and the pattern assembly 700 can be disassembled therefrom for replacement or maintenance.

[0049] Further, both the upper cover 310 and the middle frame 210 are aluminum alloy parts formed by integral die-casting to reduce the self-weight of this waterproof stage lamp. To make the connection between the lamp body and the rotating arm crossbeam 100 more stable, the middle cover assembly 200 further includes a support plate 240, which is a metal plate. The support plate 240 is fixedly installed on the extension 211 of the middle frame 210, and the support plate 240 is rotatably connected to the rotating arm 110, so that the pressure is mainly borne by the support plate 240.

[0050] The above is a specific description of the preferred embodiment of the present application. However, the present invention is not limited to the described embodiment.
