Description

Technical Field

[0001] This utility model relates to the technical field of stage moving head lights, specifically a waterproof and heat-dissipating stage moving head light. Background Technology

[0002] Traditional moving head lights typically employ a closed design with densely packed internal components, especially the light source and driver, which generate significant heat during prolonged operation. Current technologies primarily rely on natural convection or small fans for cooling, which is inefficient and unable to quickly dissipate heat, leading to excessively high internal temperatures. This high-temperature environment accelerates the aging of electronic components, shortens the lifespan of the light fixture, and affects the stability of the lighting effects. Furthermore, high temperatures can cause reduced bulb brightness, color distortion, and even circuit malfunctions, increasing maintenance costs. Therefore, we propose a waterproof, heat-dissipating stage moving head light. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This waterproof, heat-dissipating stage moving head light uses a sealed design between the outer shell and the lamp body to prevent external moisture from contacting the internal electrical components, thus protecting the lamp body. A heat dissipation sleeve is then installed around the lamp body, along with an inlet and outlet chamber, allowing coolant to be continuously injected into the heat dissipation sleeve to cool the lamp body and improve the stability of the lamp's operation.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a waterproof heat dissipation stage moving head light, including a base 1, a rotating disk 11 rotatably mounted on the upper end of the inner cavity of the base 1, a bracket 15 symmetrically arranged fixedly mounted on the upper end of the rotating disk 11, a housing 13 rotatably mounted between the two brackets 15, a lamp body 14 fixedly mounted inside the housing 13, the housing 13 and the lamp body 14 are sealed together, a heat dissipation sleeve 2 is fixedly mounted on the outer periphery of the lamp body 14, and liquid inlet chamber 23 and liquid outlet chamber 24 are respectively opened in the two side brackets 15, the liquid inlet chamber 23 and the liquid outlet chamber 24 are respectively connected to the two sides of the inner cavity of the heat dissipation sleeve 2.

[0026] Working principle: During use, the rotatable connection between the base 1 and the rotating disk 11 and between the bracket 15 and the outer shell 13 allows the illumination angle of the lamp body 14 to be adjusted in various directions, improving the stage performance. A heat dissipation sleeve 2 is set around the lamp body 14. Through the liquid inlet chamber 23 and the liquid outlet chamber 24, coolant can be continuously injected into the heat dissipation sleeve 2 to dissipate heat from the lamp body 14 and improve the stability of the lamp body 14 operation.

[0027] As a further description of the above technical solution: A driven gear ring 32 is fixedly installed on the inner wall of the rotating disk 11; a first drive motor 3 is fixedly installed inside the base 1; a drive gear 31 is fixedly installed on the upper end of the first drive motor 3 through its output shaft; the drive gear 31 and the driven gear ring 32 are meshed together; limit rotation holes 16 are opened on the inner side of the two brackets 15; limit rotation rods 17 are fixedly installed at both ends of the outer shell 13; the limit rotation rods 17 are rotatably installed in the limit rotation holes 16; and drive rods 45 are rotatably installed inside the two brackets 15. The outer end is rotatably connected via a limiting rotating rod 17; a hydraulic push rod 4 is fixedly installed on the inner wall of the base 1, and a second drive motor 41 is fixedly installed on the outer end of the hydraulic push rod 4 via its output shaft, and a first gear 42 is fixedly installed on the outer end of the second drive motor 41 via its output shaft; a second bevel gear 46 is fixedly installed in the middle of the limiting rotating rod 17, and a first bevel gear 44 that meshes with the second bevel gear 46 is rotatably installed on the upper end of the rotating disk 11, and a second gear 43 is fixedly installed on the lower end of the first bevel gear 44, and the second gear 43 meshes with the first gear 42.

[0028] Specifically, when it is necessary to adjust the horizontal angle of the lamp body 14, the first drive motor 3 is started. Through the meshing connection between its output shaft and the drive gear 31 and the driven gear ring 32, the rotating disk 11 can be driven to rotate on the upper end of the base 1, thereby achieving the effect of adjusting the horizontal angle of the lamp body 14.

[0029] When it is necessary to adjust the longitudinal angle of the lamp body 14, the second drive motor 41 is started. Through the meshing connection between its output shaft and the first gear 42 and the second gear 43, the drive rod 45 can be driven to rotate between the two brackets 15. Then, through the meshing connection between the first bevel gear 44 and the second bevel gear 46, and in conjunction with the transmission belt, the lamp body 14 can be driven to rotate between the two brackets 15, thereby achieving the effect of adjusting its longitudinal angle.

[0030] The system includes a hydraulic push rod 4. When the horizontal angle of the lamp body 14 needs to be adjusted individually, the hydraulic push rod 4 can drive the second drive motor 41 to move, causing the first gear 42 and the second gear 43 to separate from each other, thus preventing the rotating disk 11 from rotating and driving the drive rod 45 to rotate.

[0031] As a further description of the above technical solution: the outer periphery of the two limiting rotating rods 17 is respectively provided with a liquid inlet groove 230 and a liquid outlet groove 240, the outer periphery of the heat dissipation sleeve 2 is provided with a liquid inlet hole 233 communicating with the liquid inlet groove 230 and a liquid outlet hole 243 communicating with the liquid outlet groove 240; the inner wall of the base 1 is provided with a liquid inlet annular cavity 232 and a liquid outlet annular cavity 242, a liquid inlet pipe 231 is fixedly installed at the lower end of the liquid inlet cavity 23, the outer end of the liquid inlet pipe 231 is communicating with the liquid inlet annular cavity 232, and a liquid outlet pipe 241 is fixedly installed at the lower end of the liquid outlet cavity 24, the outer end of the liquid outlet pipe 241 is communicating with the liquid outlet annular cavity 242.

[0032] Specifically, when guiding the coolant, the inlet annular cavity 232 and the outlet annular cavity 242 are connected to the external coolant storage device through a conduit. The internal delivery pump of the external coolant storage device is started, and the coolant can be injected into the heat sink 2 through the inlet annular cavity 232, inlet pipe 231, inlet chamber 23, inlet tank 230 and inlet hole 233. Then, the coolant can be guided back into the coolant storage device through the outlet hole 243, outlet tank 240, outlet chamber 24, outlet pipe 241 and outlet annular cavity 242, so as to achieve the effect of circulating and guiding the coolant, thereby improving the heat dissipation effect of the lamp body 14.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
