Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more particularly to a stage lamp with a lamp housing which is convenient to assemble and disassemble. Background Art

[0002] The stage light housing not only gives the lamp a unique design and increases its recognition, but more importantly, it effectively protects the internal components of the lamp from dust and water. The stage light housings on the market are generally installed in several ways. One way is to divide the lamp housing into front and rear side covers, as shown in the utility model patent CN219976250U. Only one of the side covers needs to be removed for maintenance. Another way is to separate at least two housings along the length of the lamp head for splicing, as shown in the invention patent CN105953145B. The advantage of this is that when the radiator needs maintenance, the lower housing can be disassembled separately for operation without disassembling the main housing.

[0003] When the pivot axis between the lamp head and the support arm needs maintenance, both splicing methods require multiple shells to be removed before the pivot axis can be exposed for operation, which makes it difficult to quickly disassemble and assemble, and the maintenance work is inefficient. At the same time, the integrated front and rear covers are difficult to achieve complex shapes, which makes the overall shape of the lamp body relatively simple; and because the front and rear covers are long at the joint, they are easily squeezed and deformed after long-term use, which ultimately affects the waterproof and dustproof performance of the shell. Utility Model Content

[0004] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a stage lamp with a lamp housing that is easy to disassemble and assemble. By separating the lamp head side cover into upper and lower parts, quick disassembly and assembly can be achieved, and the need to remove the lamp head from the support arm during maintenance is avoided, thereby facilitating maintenance.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: to provide a stage lamp with a lamp shell that is easy to disassemble and assemble, including a cylindrical lamp head with a light outlet, a support arm and a rotating assembly that pivotally connects the lamp head to the support arm, the rotating assembly includes a pivot axis, the lamp head includes two relatively arranged support frame plates, and a light source installed between the support frame plates and used to generate a light beam, the support frame plates are pivotally connected to the support arm through the pivot axis, each of the support frame plates is covered with a first cover plate and a second cover plate on the outer side, and along the light emitting direction of the light source, the second cover plate and the first cover plate are sequentially arranged on both sides of the pivot axis, an air guide channel is formed between the first cover plate, the second cover plate and the support frame plate, and a first fan for actuating air flow is provided in the air guide channel.

[0006] By providing the first cover plate and the second cover plate that can be spliced ​​with each other, the support frame plate can be dustproof and waterproof; at the same time, the heat dissipation duct is provided on both sides of the lamp holder, and the heat attached to the support frame plate is promptly taken away by the flow of air, thereby improving the heat dissipation effect. However, since the flow of air will cause dust or oil to remain inside the heat dissipation duct, the existing solution can easily complete the cleaning by removing only the first cover plate and the second cover plate. The first cover plate and the second cover plate are located on both sides of the pivot axis. When the internal components of the lamp holder or the rotating components need maintenance, the lamp holder can remain pivoted to the support arm to complete the complete disassembly and assembly of its outer shell, which is convenient and quick. In addition, such a structure can be processed by split molds to form more complex lamp shapes, making the lamp more beautiful and increasing recognition.

[0007] Furthermore, the rotating assembly further comprises a sleeve slidably sleeved outside the pivot shaft and a fixed plate connected to the outer edge of the sleeve, the pivot shaft is fixedly connected to the support arm, the sleeve is fixed to the support frame plate; the first cover plate and the second cover plate are both clamped to the fixed plate at one end close to each other. By providing the first cover plate and the second cover plate with the fixed plate for clamping, the first cover plate and the second cover plate can be conveniently disassembled and assembled.

[0008] Furthermore, the first cover plate and the second cover plate located outside the same support frame plate are spliced ​​at their ends, and together form a clearance hole for avoiding the pivot axis. The pivot axis passes through the clearance hole, so that the spliced ​​first cover plate and the second cover plate can rotate around the pivot axis.

[0009] Furthermore, the first cover plate and / or the second cover plate are provided with a first clamping plate and a second clamping plate for clamping the fixed disk at one end close to each other, and the first clamping plate and the second clamping plate are respectively located on both sides of the fixed disk. The clamping is achieved by inserting the fixed disk into the range defined by the first clamping plate and the second clamping plate, which is convenient and quick.

[0010] Furthermore, the first clamping plate and the second clamping plate are arranged at intervals along the edge of the fixed disk. By arranging at intervals, the movement of the fixed disk can be limited from at least two positions, so as to firmly clamp the fixed disk.

[0011] Furthermore, the first cover plate and the second cover plate on the same side of the support frame plate are provided with first and second buckle edges that can be buckled with each other. The first and second buckle edges cooperate to make the first and second cover plates buckled more tightly.

[0012] Furthermore, the lamp holder further comprises a light output mirror covering the light output port and a mounting plate for mounting the light output mirror, and at least one mounting portion is extended toward the mounting plate from one end of the first cover plate close to the light output port. When the first cover plate is slid downward for installation, the mounting plate restricts the first cover plate from sliding further downward, so that one end of the first cover plate is more firmly mounted on the mounting plate.

[0013] Furthermore, the lamp holder also includes two shells that are buckled on the support frame plate at both sides, and the shells are sealed and connected to the support frame plate to form a cylindrical structure. Through such an arrangement, the waterproof performance of the interior of the lamp holder is guaranteed, and the components in the lamp holder are prevented from being affected by external water vapor.

[0014] Furthermore, the lamp head is separated by a partition along its length direction to form a heat dissipation cavity for installing the radiator and a mounting cavity for installing the light source. The two shells are sealed and connected to the partition. The heat dissipation cavity is formed by the rear end of the shell extending away from the light outlet, and the two sides are spliced ​​together with the two second cover plates. The mounting cavity is separated from the heat dissipation cavity by the partition, and the mounting cavity maintains good waterproof performance. At the same time, the heat dissipation cavity spliced ​​by the second cover plate and the shell can be set to a state of communication with the outside world, effectively improving the efficiency of heat exchange between the radiator and the outside world, so that the lamp has both effective waterproof performance and efficient heat dissipation.

[0015] Furthermore, the first cover plate, the second cover plate and the support frame plate are sealed at both sides by the edge of the shell, so that air flows in the air guide channel along the length direction of the lamp holder. The air entering the air guide channel can be guided to flow in an orderly manner, further improving the heat dissipation efficiency and preventing the internal components of the lamp holder from being damaged due to long-term high-temperature working conditions.

The first cover plate 410 and the second cover plate 420 are located on both sides of the pivot shaft 310. When the internal components of the lamp holder 100 or the rotating component 300 need to be maintained, the lamp holder 100 can remain in a state of being pivoted to the support arm 200 to complete the complete disassembly and assembly of its shell, which is convenient and quick.
