Description

Technical Field

[0001] This invention relates to the field of stage lighting, and more specifically to an array-type multi-head stage light with waterproof properties. Background Technology

[0002] Stage lighting, also known as "stage illumination" or simply "lighting," is one of the means of stage art design. It uses stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) and technical means to display the environment, create atmosphere, highlight central characters, create a sense of stage space and time, shape the external image of the stage performance, and provide necessary lighting effects as the plot develops.

[0003] Typical stage lights dissipate heat generated during operation by creating ventilation holes on the outer casing. Since these ventilation holes are directly exposed to the external environment, when it rains or water is splashed on them, external water can easily flow into the stage light, causing a short circuit and resulting in damage.

[0004] While existing stage lights with waterproof structures prevent water from entering the device, their overall structure is not compact enough, making them unsuitable for array arrangement and thus unsuitable for use in array-type multi-head stage lights. They require further improvement and refinement. Summary of the Invention

[0005] In view of this, it is necessary to provide a waterproof array-type multi-head stage light to address the problems existing in the prior art, thereby improving the waterproof performance of the array-type multi-head stage light through a simple and compact structure.

The first to Nth cables 4 are respectively arranged in the wiring cavities 20 of the first to Nth support arms 2. One end of the cable 4 extends into the base 1 from the lower end of the wiring cavity 20 and is connected to the power supply and main control circuit board in the base 1.

[0030] Combination Figure 3 As shown, a fixing and protective clip 21 is also provided on the second to Nth support arms 2. The fixing and protective clip 21 is semi-circular arched and is located above the first shaft end cover 61 and the second shaft end cover 62. The two ends of the fixing and protective clip 21 are respectively fixedly connected to the corresponding support arm 2 by screws.

[0031] like Figure 6 As shown, each lamp tube 3 includes a lamp tube housing 31, a connecting tube 32, a light source 34, a control circuit board 33, a heat sink 35, an optical lens 36, a light-emitting lens 37, and a sealing frame cover 38.

[0032] Both the lamp housing 31 and the connecting cylinder 32 are hollow rectangular columns. The connecting cylinder 32 is fixedly connected to the upper end of the lamp housing 31. The upper end surface of the heat sink 35 covers the lower end surface of the lamp housing 31 and is fixedly connected to the lamp housing 31. The light source 34 is installed on the upper end surface of the heat sink 35 through the sub-control circuit board 33 and is located inside the lamp housing 31. The optical lens 36 is installed inside the connecting cylinder 32. The sealing frame cover 38 is fixedly connected to the upper end of the connecting cylinder 32 and presses the light-emitting lens 37 to cover the upper end surface of the connecting cylinder 32.

[0033] To enhance waterproofing, a first sealing ring 71 is provided at the connection between the lamp housing 31 and the control circuit board 33; a second sealing ring 72 is provided at the connection between the lamp housing 31 and the connecting cylinder 32; and a third sealing ring 73 is provided between the light-emitting lens 37 and the sealing frame cover 38. Sealing rings are also provided between the first shaft end cover 61 and the first bearing 51, and between the second shaft end cover 62 and the second bearing 52.

Through the above structure, the second synchronous pulley 305 is relatively fixed to the support arm 2 through the inner ring of the second bearing 52 and the second shaft end cover 62. When the rotation control motor 304 drives the first synchronous pulley 306 to rotate, since the second synchronous pulley 305 cannot rotate on its own, the synchronous belt 307 causes the first synchronous pulley 306 to revolve around the second synchronous pulley 305, thereby driving the lamp housing 31 to rotate relative to the support arm 2, realizing the angle adjustment of the lamp housing 3.

[0036] Furthermore, each lamp tube 3 is also provided with a heat dissipation fan 39 and a defogging fan 308. The heat dissipation fan 39 is fixedly connected to the radiator 35, and the defogging fan 308 is fixedly connected to the inner wall of the lamp tube housing 31.

[0037] The light source 34, zoom control module, lamp rotation control module, cooling fan 39 and defogging fan 308 in each lamp tube 3 are respectively connected to the sub-control circuit board 33 in the same lamp tube 3. The sub-control circuit boards 33 in the first to Nth lamp tubes 3 are respectively connected to the power supply and the main control circuit board in the base 1 through the first to Nth cables 4, so that each lamp tube 3 can be controlled independently.

[0038] This invention achieves a multi-lamp array structure through a simple and compact modular design, which can flexibly adjust the number of lamps in the stage light array according to actual needs. At the same time, each lamp is independently powered and controlled by an independent cable, and the cable is introduced into the lamp through the wiring cavity on the support arm, which ensures the waterproof design of the stage light and can effectively avoid short circuit problems caused by external water coming into contact with the cable or flowing into the stage light.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
