Description

Technical Field

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

[0002] Stage lights, as a type of lighting application, require long-distance projection and high-brightness light sources. Higher brightness generates more heat, so current technology requires dedicated heat sinks for the light source, with the light source positioned as close to the sink as possible to ensure efficient heat dissipation. Given the limited internal space of stage lighting fixtures, the light source and heat sink are often designed in a stacked structure. When maintenance is needed, the entire heat sink must be disassembled before the light source can be disassembled and maintained, a cumbersome and redundant process. Furthermore, repeated disassembly and reassembly of the heat sink can lead to wear and tear, resulting in assembly errors and potentially affecting the proper reassembly of the stage light after maintenance. Utility Model Content

[0003] To overcome at least one of the defects of the prior art, this utility model provides a stage light with a direct-push device, which allows for maintenance of the light source without disassembling the heat sink, reducing redundant steps in maintaining the light source and avoiding mechanical wear caused by repeated disassembly of the heat sink.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stage light with a direct-push light source, including a base housing and a support arm pivotally connected to the base housing. A lamp head is pivotally connected to the support arm. The lamp head includes a support frame, a light source module, and a heat dissipation module for cooling the light source module. The heat dissipation module is fixed to the support frame. It also includes a sliding track for guiding the movement of the light source module, a limiting member for blocking the light source module at a predetermined position, and a locking member for locking the light source module at a predetermined position.

[0005] The heat dissipation module is fixed to the supporting lamp holder, and the light source module can move along the path provided by the sliding track. When maintenance of the light source module is required, the locking member can be removed and the light source module can be pulled out from the supporting lamp holder without disassembling the heat dissipation module. When maintenance is completed, the light source module is pushed along the sliding track until it abuts against the limiting member, and finally the locking member is used to fix the light source module to the supporting lamp holder to complete the maintenance. This reduces redundant steps when maintaining the light source and avoids mechanical wear caused by disassembling the heat dissipation module multiple times.

[0006] Furthermore, the light source module includes a connecting substrate and a light source box fixed to the connecting substrate. The connecting substrate is used to connect the supporting lamp holder and the light source, and at the same time fixes the light source at a specific position in the light path; the light source box can be used to enclose the light source to prevent stray light from escaping, and can also block the heat generated by the light source from directly affecting the surrounding components, thus playing a heat insulation role.

[0007] Furthermore, the sliding track includes a slot located on the supporting lamp holder that guides the translation of the connecting base plate, into which the connecting base plate is inserted and slids within the slot. Alignment of the connecting base plate with the slot enables more precise positioning and installation.

[0008] Furthermore, the supporting lamp holder is provided with at least one slot at each end of the connecting substrate. The two sides of the supporting lamp holder can support the two sides of the connecting substrate through the slots, so that the connecting substrate can be placed perpendicular to the optical path, which facilitates the installation and fixation of the light source module in the optical path.

[0009] Furthermore, the sliding track includes at least one strip plate that conforms to the outer edge of the light source box and extends along the direction of movement of the light source box. The strip plate is fixed to the heat dissipation module near the light source. The strip plate has a simple structure and can be used to guide the installation of the light source box, avoiding installation errors.

[0010] Furthermore, the limiting member is a stop bar, and when the light source box is located at the predetermined position, the light source box abuts against the limiting member. The stop bar has a simple structure, and the light source box can stay in the predetermined position by adhering to the stop bar, further avoiding installation errors.

[0011] Furthermore, the sliding track includes a sliding groove formed by a recess on the side of the heat dissipation module near the light source, and the outer side of the light source box abuts against the side wall of the sliding groove. The light source box can be fully embedded in the sliding groove, allowing it to move precisely in the guiding direction and reducing displacement deviation.

[0012] Furthermore, the locking member is disposed on the connecting base plate and locks the light source module by connecting the connecting base plate and the supporting lamp holder. After the connecting base plate slides to the predetermined position, it is fixed to the supporting lamp holder by the locking member to prevent the connecting base plate from falling off during operation.

[0013] Furthermore, the locking member includes a fixing end perpendicular to each other for fixing to the connecting base plate and a limiting end that abuts against and connects to the supporting lamp holder. The fixing end can be used to fix the connecting base plate, and the limiting end can be used to fix the supporting lamp holder, thereby realizing the fixed connection between the connecting base plate and the supporting lamp holder.

[0014] Furthermore, the connecting substrate has a vertically extending lifting strip on its side adjacent to the supporting lamp holder. This facilitates the lifting of the light source module by maintenance personnel during maintenance. Attached Figure Description
