Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, specifically a single-arm moving head light. Background Technology

[0002] Moving head lights are frequently used in stage lighting. The light head of a moving head light can be rotated via a rotating arm, causing the light emitted from the light head to move across the stage, achieving changing lighting effects. Currently, moving head lights are generally U-shaped rocker arm moving head lights, such as... Figure 4 As shown, the moving head light includes a base, a U-shaped rocker arm, and a lamp head. The U-shaped rocker arm is pivotally connected to the base, and the left and right sides of the lamp head are pivotally connected between the opposite side walls of the U-shaped rocker arm. This type of moving head light typically has the following problems: 1. Limited rotational freedom, resulting in fewer achievable lighting effects and a smaller lighting range; 2. Because the left and right sides of the lamp head are pivotally connected between the opposite side walls of the U-shaped rocker arm, the sides of the lamp head are largely obscured by the opposite side walls of the U-shaped rocker arm, and the lamp head can only swing back and forth within a certain range relative to the U-shaped rocker arm. This makes it unsuitable to install lamp modules on the sides of the lamp head, and usually only lamp modules are installed on the top of the lamp head, which also results in fewer achievable lighting effects and a smaller lighting range. Utility Model Content

[0003] To address the aforementioned issues, the present invention aims to provide a single-arm moving head light with greater rotational freedom, lamp modules on both the top and side surfaces of the lamp head, enabling richer lighting effects and a wider illumination range.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be directly connected or indirectly connected through intermediate elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figure 1-3 As shown, this embodiment provides a single-arm moving head light, including a base 1, a first rocker arm 2, a second rocker arm 3, a lamp head 4, and a first drive mechanism 51, a second drive mechanism 52, and a third drive mechanism 53. One end of the first rocker arm 2 is pivotally connected to the top of the base 1. The first drive mechanism 51 can drive the first rocker arm 2 to rotate relative to the base 1 around a first axis. One end of the second rocker arm 3 is pivotally connected to the other end of the first rocker arm 2. The second drive mechanism 52 can drive the second rocker arm 3 to rotate relative to the first rocker arm 2 around a second axis. The bottom of the lamp head 4 is pivotally connected to the other end of the second rocker arm 3. The third drive mechanism 53 can drive the lamp head 4 to rotate relative to the second rocker arm 3 around a third axis. The second axis is perpendicular to the first axis, and the third axis is perpendicular to the second axis. The top and side of the lamp head 4 are respectively provided with a top lamp module 41 and a side lamp module 42. The first rocker arm 2 and the second rocker arm 3 are both L-shaped structures. When the moving head light is in a folded state, the lamp head 4 can be stored in the arm bend of the second rocker arm 3, and the second rocker arm 3 can be stored in the arm bend of the first rocker arm 2.

[0023] The single-arm moving head light provided in this embodiment replaces the traditional U-shaped moving head light with a single-sided rocker arm formed by the first rocker arm 2 and the second rocker arm 3 connected in sequence. This allows the lamp head 4 to be connected only to the second rocker arm 3 at its bottom, without the side of the lamp head 4 being obstructed or restricted. Therefore, a top light module 41 and a side light module 42 can be set on the top and side of the lamp head 4, respectively, thereby achieving richer lighting effects and a larger lighting range. Moreover, both the first rocker arm 2 and the second rocker arm 3 are L-shaped structures, which not only facilitates the sequential connection of the base 1, the first rocker arm 2, the second rocker arm 3, and the lamp head 4, but also makes the moving head light more compact in the folded state, occupying less space and facilitating storage and transportation.

[0024] In a preferred embodiment, the lamp head 4 includes a lamp housing and a heat dissipation assembly disposed within the lamp housing. The heat dissipation assembly includes several heat dissipation plates 44 arranged in a ring and vertically positioned, thereby dividing the interior of the lamp housing into a first lamp cavity 45 located inside the heat dissipation assembly and a second lamp cavity 46 located outside the heat dissipation assembly. The top lamp module 41 is located within the first lamp cavity 45, and the side lamp module 42 is located within the second lamp cavity 46. The top and sides of the lamp housing are respectively provided with top light outlets and side light outlets corresponding to the top lamp module 41 and the side lamp module 42. In this embodiment, the heat dissipation assembly divides the interior of the lamp housing into the first lamp cavity 45 and the second lamp cavity 46, thereby facilitating the heat dissipation assembly to dissipate heat from the top lamp module 41 and the side lamp module 42 respectively disposed within the first lamp cavity 45 and the second lamp cavity 46. In this embodiment, preferably, the upper and lower ends of the heat dissipation assembly abut against and connect to the top and bottom of the lamp housing, thereby preventing the light emitted by the lamp module in the first lamp cavity 45 or the second lamp cavity 46 from dissipating into the other lamp cavity and affecting the lighting effect of the stage light. In other embodiments, the heat dissipation component may also adopt an integrated annular structure heat sink.

[0025] In a preferred embodiment, the lamp housing includes an upper lamp housing 47 and a lower lamp housing 48 connected by interlocking screws.

The upper lamp housing 47 and the lower lamp housing 48 each have several connecting posts 483 extending towards each other for screw thread connection. Each connecting post 483 is located between two adjacent heat sinks 44, thereby sealing the gaps between the heat sinks 44 and preventing light from escaping between the two lamp cavities. In this embodiment, the lamp housing is composed of a detachably connected upper lamp housing 47 and a lower lamp housing 48. Each heat sink 44 constituting the heat dissipation assembly is inserted into a first slot 481 inside the lamp housing. Therefore, only the upper lamp housing 47 needs to be opened to disassemble or replace each heat sink 44, making maintenance convenient.

[0026] In a preferred embodiment, the number of side light modules 42 is several and they are distributed circumferentially along the side of the lamp head 4. The lower lamp housing 48 is provided with several second slots 482, and at least a portion of each side light module 42 is inserted into the corresponding second slot 482. In this embodiment, the lamp housing is also provided with second slots 482, so that each side module can be disassembled or replaced simply by opening the upper lamp housing 47, making maintenance convenient.

[0027] As a preferred embodiment, the side light module 42 includes several laser light modules 421 and several strobe light modules 422, with each laser light module 421 and each strobe light module 422 arranged sequentially at intervals. The strobe light modules 422 are vertically inserted into the corresponding second slots 482. The lamp head 4 is provided with a main circuit board, and the back of the strobe light module 422 is provided with wires. The other end of the wires is connected to the main circuit board through a plug-in terminal (omitted in the figure). The laser light module 421 includes a laser light plate 4211 and a lens 4212 arranged opposite to each other, wherein the lens 4212 is inserted into the corresponding second slot 482. The number of heat sinks 44 is the same as the number of laser light modules 421. The front of the laser light plate 4211 is attached to and connected to the corresponding heat sink 44 to facilitate heat dissipation of the laser light plate 4211 by the heat sink 44. Each strobe light module 422 is respectively arranged opposite to each other at the corner where two adjacent heat sinks 44 are connected. In this solution, the side light module 42 includes several laser light modules 421 and several strobe light modules 422, thereby making the side light output effect of the lamp head 4 more abundant.

The third drive mechanism 53 includes a third motor 531 connected to the second rocker arm 3, a third driving wheel 532 mounted on the output shaft of the third motor 531, a third driven wheel 533 connected to the lamp head 4, and a third transmission belt fitted on the third driving wheel 532 and the third driven wheel 533, enabling the lamp head 4 to rotate relative to the second rocker arm 3 via the third motor 531. The various transmission belts are omitted in the attached drawings.

By providing a rotatable honeycomb lens 413, the lighting effects of the top light module 41 are made more diverse and varied. In other embodiments, the top light module 41 may also employ other types of light modules.
