[0002] With the development of the cultural tourism landscape, stage performances and sports events market, there are more and more high-power lamps. Due to the high power and high temperature of the lamps, natural heat dissipation cannot dissipate the heat generated by the light source in time, and the light source needs to be forced to dissipate heat. Especially for lamps whose light source is an ultra-short arc plasma bulb, the temperature of the wick is very high when the light source is working. In addition, when the lamp is shaking its head and rotating, the bulb rotates with the lamp. Due to the effects of gravity and thermal expansion, the temperature of each point of the bulb is extremely uneven. The existing light source cooling system cannot accurately cool each area of ​​the light source, which will cause the light source to be locally overcooled or insufficiently cooled, resulting in irreparable consequences such as shortening the life of the light source or even damaging the light source. When the temperature difference of the bulb reaches a certain level, the bulb is prone to bursting. Utility Model Content

[0032] Refer to the following Figures 1 to 6 The heat dissipation system of a lamp according to an embodiment of the present application is described.

[0033] The heat dissipation system of the lamp in the embodiment of the present application is as follows Figures 1 to 6As shown, the light source assembly 100 and the first air supply assembly 200 are included. The light source assembly 100 includes a lamp holder 110 and a lamp body disposed on the lamp holder 110. The first air supply assembly 200 is used to blow air to the lamp body on the lamp holder 110 to cool the lamp body. The first air supply assembly 200 includes a first fan 210 and a first driving component 220. The first fan 210 can be rotatably mounted on the lamp holder 110. The first driving component 220 can drive the first fan 210 to move relative to the lamp holder 110. Specifically, the first fan 210 is provided with an air outlet 215 and a guide member 230. The guide member 230 is covered at the air outlet 215 to guide the air discharged by the first fan 210. The lamp holder 110 is provided with a flow divider 111, and the flow guide 230 cooperates with the flow divider 111 to form a first opening 241 and a second opening 242. The first opening 241 and the second opening 242 can divide the air flow of the first fan 210 to cool different positions of the lamp body. It can be understood that the flow divider 111 is fixedly arranged on the lamp holder 110, and the flow guide 230 is arranged at the air outlet 215 of the first fan 210. The first driving component 220 drives the first fan 210 to rotate relative to the lamp holder 110. The flow guide 230 arranged at the air outlet 215 moves relative to the flow divider 111 on the lamp holder 110 under the action of the first driving component 220. The movement of the flow guide 230 relative to the flow divider 111 can change the area of ​​the first opening 241 and the second opening 242, thereby adjusting the size of the first opening 241 and the second opening 242. By adjusting the size of the first opening 241 and the second opening 242, the direction and size of the air outlet of the first fan 210 can be controlled, and the required air volume can be directed to different positions of the lamp body, so that large air volume cooling can be achieved for positions with excessively high temperatures, so that the temperature difference of each point on the lamp body is within an allowable range, thereby avoiding damage to the lamp body and ensuring the life of the lamp.

[0034] It is understandable that when the lamp rotates in a certain pattern, by controlling the action of the first driving component 220, it is possible to ensure that the sizes of the first opening 241 and the second opening 242 are adjusted in real time with the position of the lamp when it rotates. When the temperature of the side facing the first opening 241 is higher, the first driving component 220 drives the first fan 210 to move, and at this time, the guide member 230 moves relative to the diverter 111 to make the first opening 241 larger and the second opening 242 smaller, thereby efficiently cooling the side facing the first opening 241; when the temperature of the side facing the second opening 242 is higher, the guide member 230 moves relative to the diverter 111 to make the first opening 241 smaller and the second opening 242 larger, thereby achieving efficient cooling of the side facing the second opening 242.

[0035] Reference Figure 3 and Figure 4According to some embodiments of the present application, the guide member 230 includes a cover body 231 and a base plate 232. The cover body 231 is covered on the base plate 232. Notches 234 are provided on both sides of the cover body 231. The diverter portion 111 is provided in the middle of the cover body 231. The diverter portion 111 cooperates with the notch 234 to separate the cover body 231 into a first opening 241 and a second opening 242. The guide member 230 is arranged at the air outlet 215 of the first fan 210. Specifically, the guide member 230 includes a cover body 231 and a base plate 232. The cover body 231 is covered on the base plate 232. Notches 234 are arranged on both sides of the cover body 231. A diverter portion 111 is arranged on the lamp holder 110. The diverter portion 111 is installed in the middle of the cover body 231. The cooling fluid blown from the first fan 210 toward the lamp body flows out toward the notches 234 on both sides under the action of the diverter portion 111. That is, at this time, the guide member 230 and the diverter portion 111 cooperate to form a first opening 241 and a second opening 242. The first opening 241 and the second opening 242 can divert the air outlet of the first fan 210 to cool different positions of the lamp body.

[0036] Reference Figure 3 and Figure 4 According to some embodiments of the present application, the cover 231 is gradually reduced in size in a direction away from the air outlet 215. The cover 231 is arranged to cover the air outlet 215, and the cover 231 is gradually reduced in size in a direction away from the air outlet 215. When the wind blows out from the air outlet 215, since the cover 231 outside the air outlet 215 gradually becomes smaller, the blown wind will be accelerated to spray to the designated area, thereby improving the cooling effect.

Specifically, the first fan 210 is provided with an air outlet 215 and a guide member 230, and the guide member 230 includes a cover body 231 and a bottom plate 232. A connecting shaft 233 is provided below the bottom plate 232, and the lamp holder 110 is provided with a connecting hole 112. The cover body 231 and the bottom plate 232 are installed in the connecting hole 112 of the lamp holder 110 through the connecting shaft 233. The connecting shaft 233 can rotate relative to the connecting hole 112, so that the guide member 230 can move relative to the diverter 111 on the lamp holder 110, so as to adjust the size of the first opening 241 and the second opening 242.

Specifically, the first driving component 220 is provided with a gear 221, and the first fan 210 is provided with a rack 214 meshed with the gear 221. The gear 221 of the first driving component 220 rotates to drive the rack 214 to move, and the rack 214 transmits the movement to the first fan 210, so that the first fan 210 can move relative to the lamp holder 110, thereby adjusting the size of the first opening 241 and the second opening 242.
