Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and more specifically, to a stage light with a simplified arm. Background Technology

[0002] Stage lighting, as a type of stage lighting equipment, needs to adapt to various performance venues, especially outdoor venues where space and portability are paramount. To meet the structural strength and basic functional requirements of the lighting fixture support frame, most existing support frames rely on cutting and bending sheet metal parts, then assembling multiple components using bolts, rivets, or welding. This results in a large number of parts and complex structures, making it difficult to guarantee assembly precision and leading to significant cumulative errors. Most importantly, the splicing assembly process results in poor waterproofing performance. With the increasing precision and intelligence of stage lighting fixtures, and the ever-increasing demands for equipment protection in various environments, the market urgently needs a solution that is innovative in structural design, manufacturing processes, and material application, fundamentally solving or significantly improving these pain points. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a stage light with a simplified arm. While meeting the structural strength and basic functions of the support arm, it no longer relies on splicing, welding, or other assembly methods, thus improving the waterproof performance and installation accuracy of the support arm.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stage light with a simplified arm, including a lamp head and a support arm for supporting the rotation of the lamp head. The support arm is pivotally connected to the base housing. The lamp head and the support arm, and the support arm and the base housing are respectively pivotally connected by a rotating shaft and a bushing. The support arm includes a horizontal compartment pivotally connected to the base housing and a vertical frame plate pivotally connected to the lamp head. The two vertical frame plates are connected to both ends of the horizontal compartment and are integrally formed with the horizontal compartment. The side of the horizontal compartment away from the base housing is open to form an opening. A first cover is fastened to the opening, and a second cover is fastened to the side of the two vertical frame plates away from each other.

[0005] The support arm includes a horizontal compartment pivotally connected to the base housing and a vertical frame plate pivotally connected to the lamp head. The two ends of the horizontal compartment are connected to the vertical frame plates, thus forming a U-shaped structure. This ensures the structural strength of the support arm and facilitates the pivotal connection of the lamp head to the support arm on both sides, ensuring the balance of the connection. The two vertical frame plates and the horizontal compartment are manufactured using an integral molding method, which can greatly improve the structural precision, is not affected by assembly and transportation, shortens the processing time, and avoids gaps due to the integral design. In addition, by fastening a first cover at the opening of the horizontal compartment and a second cover on the opposite side of the vertical frame plates, the horizontal compartment and the first cover, and the vertical frame plates and the second cover form a receiving cavity, which can provide space for the installation and placement of components.

[0006] Furthermore, the rotating shaft is provided on the lamp holder and / or the base housing, and the bushing is integrally formed on the support arm. This eliminates the assembly process of the independent bushing part and its fixing components, ensuring the coaxiality accuracy of the bushing and the rotating shaft, while also improving the waterproof sealing between the support arm and the bushing.

[0007] Furthermore, the bushing is provided on the lamp holder and / or the base housing, and the pivot is integrally formed on the support arm. This eliminates the assembly process of the pivot and its fixing components, ensuring the coaxiality accuracy of the pivot and bushing, while also improving the waterproof sealing between the support arm and the pivot.

[0008] Furthermore, the horizontal compartment includes a base plate pivotally connected to the base housing. A groove is formed on the side of the base plate near the base housing corresponding to the recess of the bushing, and the bushing is located at the bottom of the groove. This ensures that the bushing is at least partially accommodated and concealed by the groove, compressing the vertical distance between the support arm and the base housing, reducing the overall vertical height of the stage light, and also reducing the exposed portion of the bushing, thus increasing aesthetics.

[0009] Furthermore, the horizontal compartment includes a base plate pivotally connected to the base chassis and a reinforcing plate connecting the vertical frame plate and the base plate. The bottom edge of the reinforcing plate is connected to the base plate, and a first side and a second side adjacent to the bottom edge are respectively connected to a vertical frame plate. The top of the reinforcing plate forms the open opening. The reinforcing plate connecting the base plate and the vertical frame plate forms a triangular structure, which enhances the connection strength, increases the side height of the horizontal compartment, increases the accommodating space of the horizontal compartment, and strengthens the overall structural strength of the support arm. The open opening at the top of the reinforcing plate facilitates the placement and installation of components.

[0010] Furthermore, the first cover is fastened to the opening and completely covers the outer surface of the horizontal compartment. This prevents the horizontal compartment from being exposed and increases aesthetics.

[0011] Furthermore, a first cover and a second cover are respectively fastened to the horizontal compartment and the vertical frame plate to form a first receiving cavity and a second receiving cavity, and the first receiving cavity and the second receiving cavity are interconnected. The interconnection between the first receiving cavity and the second receiving cavity facilitates the through-distribution and connection of the cable lines inside the support arm.

[0012] Furthermore, the first cover is fastened to the horizontal compartment and fits tightly with the side of the vertical frame plate near the lamp head. The first cover and the horizontal compartment form a first receiving cavity, and the fact that the first cover is positioned close to the vertical frame plate further ensures the sealing of the first receiving cavity.

[0013] Furthermore, a waterproof sealing strip is provided between the first cover and the open edge of the horizontal compartment, and / or a waterproof sealing strip is provided between the second cover and the edge of the vertical frame plate. The waterproof sealing strips prevent water vapor from entering, enhancing the waterproof performance of the support arm.

[0014] Furthermore, the open edge of the horizontal compartment and / or the edge of the vertical frame plate are provided with waterproof protrusions, and the waterproof protrusions are recessed to form a sealing groove for accommodating the waterproof sealing strip. The waterproof protrusions increase the sidewall thickness of the horizontal compartment, which helps to form the sealing groove, while the recessed sealing groove provides positioning and accommodation for the waterproof sealing strip.
