Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, and in particular to a heat dissipation structure for a stage lighting lamp. Background Technology

[0002] Stage lighting effectively enhances the stage performance effect, and stage lights are commonly used stage lighting equipment. Stage lights can focus the light source on a single focal point, thereby making the light source more concentrated or dispersed, forming single or multiple beams, thus creating a better stage lighting effect. During a stage performance, stage lights are arranged around the stage, with beams shining onto the stage in multiple directions to create stage lighting effects.

[0003] Currently, stage lights typically include a base, a lamp holder that can be rotatably mounted on the base, and a lamp head that can be swung on the lamp holder. The lamp head has a light-emitting lens mounted on its top, a lighting lamp inside, and several lighting effect modules arranged sequentially between the lighting lamp and the light-emitting lens to create different lighting effects. The light beam formed by the lighting lamp passes through the lighting effect modules and the light-emitting lens, and various lighting effects are created by changing different lighting effect modules.

[0004] To ensure that the beam of a lighting lamp can penetrate several lighting modules and light-emitting lenses, the lighting lamps used are usually of relatively high power. They convert some electrical energy into visible light, and the rest is consumed as heat, infrared rays, ultraviolet rays, etc. This causes the lighting lamp to generate a lot of heat during operation, which is then transferred to the light source, causing the light source temperature to become too high. This affects the lighting effect and lifespan, and may even lead to serious consequences such as the bulb turning white. Therefore, it is necessary to dissipate heat from the lighting lamp.

The finned heat sink is installed inside the base shell. Several cooling fans are respectively installed at the front and rear ends of the base shell and communicate with the finned heat sink. The lamp shell has a ventilation window formed by multiple ventilation meshes at each of the front and rear ends of the base shell. The plug-in heat sink is inserted into a ventilation window, forming a heat dissipation panel and several heat dissipation rods arranged on the upper inner wall of the heat dissipation panel. The number of heat dissipation rods is equal to or less than the number of ventilation meshes in the ventilation window, and each heat dissipation rod is inserted into a corresponding ventilation mesh.

[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figure 1 , Figure 3 A heat dissipation structure for a stage lamp is installed inside the lamp head 10 of the stage lamp. It includes a base 21, a finned heat sink 22, several cooling fans 23, and a plug-in heat sink 24. The lamp housing 11 of the lamp head 10 has a lamp mounting area 101 formed at its bottom. An illumination lamp 12 is installed in the lamp mounting area 101, one above the other, with the bottom of the illumination lamp 12 connected to the top of the base 21. (See also...) Figure 7 The finned heat sink 22 is installed inside the housing 21 and has two opposing substrates 221, a plurality of heat sink fins 222 evenly spaced between the two substrates 221 from one side to the other, and a plurality of annular heat sink pipes 223 passing through the plurality of heat sink fins 222. (See also...) Figures 4-6 The top tube segments 201 of several annular heat pipes 223 are arranged between the top of the housing 21 and the base plate 221 located at the top. The bottom tube segments 202 of several annular heat pipes 223 are respectively inserted into the middle and lower parts of several heat dissipation fins 222. The side tube segments 203 on both sides of several annular heat pipes 223 extend out to the outside of both sides of several heat dissipation fins 222. Several cooling fans 23 are respectively installed at the front and rear ends of the housing 21 and are connected to the fin heat sink 22.

[0022] See also Figure 2The lamp housing 11 has a ventilation window 13 formed by multiple ventilation meshes at the front and rear ends of the base housing 21. The insert heat sink 24 is inserted into a ventilation window 13, which forms a heat dissipation panel 241 and a number of heat dissipation rods 242 arranged on the upper part of the inner wall of the heat dissipation panel 241. The number of heat dissipation rods 242 is equal to or less than the number of ventilation meshes of the ventilation window 13. Each heat dissipation rod 242 is inserted into a ventilation mesh and can lock the ventilation mesh with the middle section of the heat dissipation rod 242.

[0023] Furthermore, in this embodiment, the housing 21 includes a top housing 211 and a bottom housing 212. The top housing 211 and the bottom housing 212 are disposed opposite each other at the top and bottom of the fin heat sink 22. The top housing 211 and the bottom housing 212 are each provided with mounting edges 31 extending toward the front end and rear end of the fin heat sink 22. The cooling fan 23 is disposed between the mounting edges 31 at the same end of the top housing 211 and the bottom housing 212. The cooling fan 23 is fixed by the mounting edges 31, and the cooling fan 23 connects the top housing 211 and the bottom housing 212.

[0024] Furthermore, in this embodiment, the length of the insert heat sink 24 is longer than the length of its corresponding vent 13. The upper part of the insert heat sink 24 matches the vent 13, while the lower part of the insert heat sink 24 extends below the vent 13. The insert heat sink 24 has a plurality of auxiliary heat sinks 243 arranged on the lower part of the inner wall of the heat dissipation panel 241, so that when the airflow is discharged from the insert heat sink 24, the auxiliary heat sinks 243 can further dissipate heat.

[0025] Understandably, the method of using the heat dissipation structure of the stage lamp of this utility model is as follows: When the lamp 12 is working, the large amount of heat generated is introduced from the top of the housing 21 into the finned heat sink 22. After the heat is rapidly diffused along several ring-shaped heat dissipation pipes 223 and several heat dissipation fins 222, the cooling fans 23 at the front and rear ends of the housing 21 transport the heat diffused by the finned heat sink 22 to the corresponding ventilation window 13 and the plug-in heat sink 24 by airflow, thereby achieving efficient heat dissipation. In addition, part of the airflow transported by the plug-in heat sink 24 can be routed from both sides of the lamp mounting area 101 to another ventilation window 13. Combined with the heat dissipation of the side pipe sections 203 on both sides of the several ring-shaped heat dissipation pipes 223, the heat dissipation efficiency is further improved.

[0026] In summary, the heat dissipation structure of the stage lamp of this utility model, through the cooperation of the housing 21, the finned heat sink 22, several cooling fans 23 and the plug-in heat sink 24, can absorb and diffuse the heat generated by the lamp 12 when it is working through the finned heat sink 22, and transport the heat diffused by the finned heat sink 22 to the corresponding ventilation window 13 and the plug-in heat sink 24 through the airflow of the cooling fans 23, thereby achieving efficient heat dissipation.

[0027] Any combination of different embodiments of this utility model, provided it does not violate the inventive concept of this utility model, shall be considered as the disclosure of this utility model; any simple modifications to the technical solution and any combination of different embodiments within the scope of the inventive concept of this utility model, without violating the inventive concept of this utility model, shall be within the protection scope of this utility model.
