Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] Please refer to Figures 1-8 This utility model provides a stage light fixture with a detachable heat dissipation device, including a lamp head 1, a heat dissipation unit 2 and a light-emitting plate 3. The front side of the lamp head 1 is provided with a lamp plate mounting cavity 101, and the light-emitting plate 3 is installed in the lamp plate mounting cavity 101.

[0041] The lamp head 1 has a heat dissipation cavity 102 in the middle and a quick-install interface 103 communicating with the heat dissipation cavity 102 on the side wall of the lamp head 1; the heat dissipation unit 2 is embedded in the heat dissipation cavity 102 and can be detachably connected to the quick-install interface 103.

[0042] The light-emitting panel 3 includes a circuit board and a light bulb. The circuit board is detachably mounted in the lamp panel mounting cavity 101, and the light bulb is electrically connected to the circuit board. The circuit board is electrically connected to an external control system, which controls whether the light bulb on the light-emitting panel 3 illuminates.

[0043] During installation, the heat dissipation unit 2 is inserted into the lamp plate mounting cavity 101, and then the heat dissipation unit 2 is detachably connected to the quick-connect interface 103, so that the heat dissipation unit 2 and the lamp head 1 can be connected to each other. When it is necessary to disassemble the heat dissipation unit 2, the heat dissipation unit 2 is removed from the quick-connect interface 103, so that the heat dissipation unit 2 and the lamp head 1 can be separated.

[0044] The lamp head 1, heat dissipation unit 2 and light-emitting board 3 can be operated and replaced independently, which is more convenient compared with the traditional integrated design. The lamp beads and heat dissipation fans, which are more prone to failure in lighting equipment, adopt quick-release design.

In a specific embodiment of this utility model, heat dissipation device 22 is specifically a cooling fan, which increases airflow, reduces the temperature of the equipment, and prevents overheating inside the stage lamp.

[0048] Specifically, the lamp head 1 includes a lampshade 11, a connector 12, and a fixing plate 13. The lampshade 11 is detachably connected to the front side of the connector 12, and the lampshade 11 and the front side of the connector 12 cooperate to form a lamp plate mounting cavity 101. The rear side of the connector 12 is provided with a first lamp holder connecting plate 121 and a second lamp holder connecting plate 122. The first lamp holder connecting plate 121 is disposed at one end of the connector 12, and the second lamp holder connecting plate 122 is disposed at the other end of the connector 12. The first lamp holder connecting plate 121 and the second lamp holder connecting plate 122 are respectively provided with a rotating device.

[0049] One end of the fixing plate 13 is detachably connected to the first lamp holder connecting plate 121, and the other end of the fixing plate 13 is detachably connected to the second lamp holder connecting plate 122; the front side of the fixing plate 13, the inner side of the first lamp holder connecting plate 121, the inner side of the second lamp holder connecting plate 122 and the rear side of the connector 12 cooperate to form a heat dissipation cavity 102.

[0050] The rotating device is used to cooperate with the external stage light bracket to realize the function of rotating the lamp head 1. The lamp cover 11 is used to house the light-emitting panel 3 and to protect the light-emitting panel 3. The connecting piece 12 and the fixing plate 13 cooperate with each other to form a heat dissipation cavity 102, which is used to house the heat dissipation device 22, thereby dissipating the heat generated by the stage light fixture during operation to the outside through the heat dissipation device 22.

[0051] Specifically, the inner side of the fixing plate 13 is provided with a plurality of first partitions 131, and the plurality of first partitions 131 are spaced apart along the length direction of the fixing plate 13; a first extension plate 132 is provided on one side of the length direction of the first partition 131, and a first heat dissipation gap is formed between adjacent first extension plates 132.

[0052] The connector 12 has a plurality of second partitions 123 on its rear side, the plurality of second partitions 123 are spaced apart, and the second partitions 123 are on the same side as the first extension plate 132; a second extension plate 124 is provided on the rear side of the second partitions 123, and a second heat dissipation gap is formed between adjacent second extension plates 124.

[0053] The first extension plate 132, the second extension plate 124, the first lamp holder connecting plate 121, and the second lamp holder connecting plate 122 cooperate to form a quick-install interface 103; the first extension plate 132 is pressed against one side of the heat dissipation unit 2, and the first heat dissipation notch cooperates with the heat dissipation unit 2 to form a first heat dissipation hole 104; the second extension plate 124 is pressed against the other side of the heat dissipation unit 2, and the second heat dissipation notch cooperates with the heat dissipation unit 2 to form a second heat dissipation hole 105.

[0054] Both the first heat dissipation hole 104 and the second heat dissipation hole 105 are connected to the heat dissipation cavity 102. With the above structure, the first heat dissipation hole 104 and the second heat dissipation hole 105 are formed by the cooperation of the first extension plate 132 on the first partition 131, the second extension plate 124 on the second partition 123 and the mounting plate 21 on the heat dissipation unit 2. There is no need to increase the height of the stage light fixture to set up heat dissipation holes, making reasonable use of space and reducing the size of the stage light fixture, making the stage light fixture more compact and convenient.

[0055] Specifically, the front end of the first extension plate 132 is provided with a first notch 1321, and the front end of the second extension plate 124 is provided with a second notch 1241; the heat dissipation unit 2 is provided with a plurality of protrusions 201 at intervals on the side away from the lamp board mounting cavity 101, and the interval of the protrusions 201 is adapted to the interval of the first heat dissipation notch and the second heat dissipation notch; the length of the protrusions 201 is greater than the width of the heat dissipation unit 2, so that one end of the protrusions 201 is tightly abutted against the first notch 1321, and the other end of the protrusions 201 is tightly abutted against the second notch 1241.

[0056] The shapes of the first notch 1321 and the second notch 1241 are respectively adapted to the corresponding ends of the protrusion 201. When the connector 12 and the fixing plate 13 are connected, and the heat dissipation unit 2 is installed in the quick-install interface 103, the above structure can increase the stability and strength of the connection between the first extension plate 132 and the protrusion 201, as well as the connection between the second extension plate 124 and the protrusion 201.

[0057] Furthermore, a third extension plate 133 is provided on the other side of the length direction of the first partition 131, and a third heat dissipation gap is formed between adjacent third extension plates 133;

[0058] The connector 12 is further provided with a plurality of third partitions 125 on its rear side. The plurality of third partitions 125 are spaced apart and are provided on the same side as the third extension plate 133. A third extension plate 126 is provided on the rear side of the third partition 125, and a fourth heat dissipation notch is formed between adjacent third extension plates 126. The third extension plate 133 abuts against the third extension plate 126, and the third heat dissipation notch and the fourth heat dissipation notch cooperate to form a third heat dissipation hole 106.

[0059] With the above structure, the third extension plate 133 and the third extension plate 126 cooperate to form a third heat dissipation hole 106 that communicates with the heat dissipation cavity 102, which is more conducive to the air flow in the heat dissipation cavity 102 and further enhances the heat dissipation effect.

[0060] In one specific embodiment of this utility model, the front end of the third extension plate 133 is provided with a third notch, and the front end of the third extension plate 126 is provided with a fourth notch; the shapes of the third notch and the fourth notch are adapted to each other, and when the connector 12 and the fixing plate 13 are connected, the third notch and the fourth notch are tightly abutted together. Using the above structure can increase the stability and strength of the connection between the third extension plate 133 and the third extension plate 126.

[0061] Furthermore, a plurality of heat dissipation plates 127 are provided on the rear side of the connector 12, and the plurality of heat dissipation plates 127 are spaced apart between the second partition 123 and the third partition 125.

[0062] With the above structure, the heat in the lamp mounting cavity 101 can be conducted to the heat dissipation cavity 102 through the heat dissipation plate 127, thereby further enhancing the heat dissipation effect.

[0063] Specifically, the inner side of the fixing plate 13, the rear side of the connector 12, the side wall of the first lamp holder connecting plate 121, and the side wall of the second lamp holder connecting plate 122 are all provided with connecting platforms 107, and the connecting platforms 107 are provided with screw holes.

[0064] The heat dissipation unit 2 is also provided with a fixing member 202 and a through hole. The through hole is adapted to the position of the connecting platform 107. The fixing member 202 passes through the through hole and is threadedly connected to the corresponding screw hole.

[0065] In one specific embodiment of this utility model, the connecting platform 107 is disposed in four positions: the first is located between the two first partitions 131 in the middle of the fixing plate 13; the second is located between the two second partitions 123 in the middle of the connector 12; the third is located on the side wall of the first lamp holder connecting plate 121; and the fourth is located on the side wall of the second lamp holder connecting plate 122. With the above structure, maintenance or replacement of the heat dissipation unit 2 only requires loosening the bolts, which is convenient and quick, and is not prone to loosening during long-term use.

[0066] Preferably, the lamp head 1 further includes a control box 14, which is detachably connected to the rear side of the lamp cover 11.

[0067] The control box 14 is used to store the control module. The control module is electrically connected to the light-emitting panel 3 and connected to an external control system. The control module can control the stage lights to achieve functions such as rotation and illumination.

[0068] In one specific embodiment of this utility model, the height of the second lamp holder connecting plate 122 is equal to the sum of the height of the first lamp holder connecting plate 121 and the control box 14. When both ends of the fixing plate 13 are connected to the first lamp holder connecting plate 121 and the second lamp holder connecting plate 122 respectively, a control box mounting notch is formed between the fixing plate 13 and the second lamp holder connecting plate 122. The control box 14 is installed in the control box mounting notch, so that the rear side of the control box 14 is flush with the rear side of the second lamp holder connecting plate 122. This structure makes the overall structure of the stage light fixture more regular, not only improving its aesthetics but also allowing for adjustment of the center of the stage light fixture, facilitating the rotation of the lamp head 1 and preventing the stage light fixture from losing balance during rotation, thus increasing the burden on the drive mechanism.

[0069] This utility model also provides a stage light, which uses the stage light fixture with a detachable heat dissipation device described above.
