[0032] Reference Figures 1 to 3 The following are several embodiments of a moving head light with heat dissipation function according to this utility model.

[0033] like Figures 1 to 3 As shown, a moving head light with heat dissipation function according to an embodiment of the present invention includes a lamp body 100, a bracket 200, and a cooling assembly 300; the lamp body 100 is rotatably connected to the bracket 200; the cooling assembly 300 includes a liquid storage tank 310 and a cooling pipe 320, the liquid storage tank 310 is fixed to the lamp body 100, and the cooling pipe 320 is disposed on the outer periphery of the lamp body 100; the liquid storage tank 310 is provided with a mixing chamber 311, and a partition 312 is provided inside the mixing chamber 311. 312 divides the mixing chamber 311 into a first chamber 3111 and a second chamber 3112, with the second chamber 3112 connected to the cooling pipe 320; the first chamber 3111 is used to contain water, and the second chamber 3112 is used to contain coolant; the partition 312 is provided with a through hole 3121 connecting the first chamber 3111 and the second chamber 3112; water from the first chamber 3111 flows into the second chamber 3112 through the through hole 3121, and the water and coolant mix to form a coolant, which then flows to the cooling pipe 320.

[0034] The lamp body 100 is used for lighting. The lamp body 100 is rotatably connected to the bracket 200, allowing it to be freely adjusted in multiple directions, thereby changing the angle and direction of the beam and providing viewers with a more impactful and varied visual experience. During operation, water is added to the first chamber 3111 and coolant to the second chamber 3112. The lamp body 100 is then turned on, emitting a beam of light and gradually heating up. The water in the first chamber 3111 slowly flows into the second chamber 3112 through the through-hole 3121, mixing with the coolant in the second chamber 3112 to form a coolant. The coolant flows into the cooling pipe 320, cooling the lamp body 100 to accelerate heat dissipation and extend its lifespan.

[0035] The lamp body 100 is rotatably connected to the bracket 200, allowing it to be freely adjusted in multiple directions to change the angle and direction of the light beam. The rotation of the lamp body 100 accelerates the flow of water from the first chamber 3111 to the second chamber 3112, facilitating coolant formation. During the initial operation of the lamp body 100, its temperature is low and requires no cooling. As the lamp body 100 continues to emit light, its temperature gradually increases. At this point, water in the first chamber 3111 slowly enters the second chamber 3112 through the through-hole 3121, forming coolant. This coolant flows into the cooling pipe 320 to cool the lamp body 100. This design allows for effective cooling as the temperature of the lamp body 100 gradually increases.

[0036] like Figure 2 As shown, in some embodiments, multiple through holes 3121 are provided, and the multiple through holes 3121 are arranged along the height direction of the moving head light on the partition 312. The multiple through holes 3121 can improve the efficiency of water flow from the first chamber 3111 to the second chamber 3112, which is beneficial for the rapid formation of coolant. In this embodiment, four through holes 3121 are provided, and the four through holes 3121 are evenly distributed on the partition 312 along the height direction of the lamp body 100.

[0037] like Figures 1 to 3 As shown, in some embodiments, the cooling assembly 300 further includes multiple solenoid valves, each corresponding to a through-hole 3121. The solenoid valve is installed in the corresponding through-hole 3121 and is used to open or close the corresponding through-hole 3121. When the solenoid valve is open, it opens the corresponding through-hole 3121, allowing water in the first chamber 3111 to flow through the through-hole 3121 to the second chamber 3112; when the solenoid valve is closed, it closes the corresponding through-hole 3121, preventing water in the first chamber 3111 from passing through the through-hole 3121. By providing multiple solenoid valves, different through-holes 3121 can be opened or closed, thereby adjusting the coolant formation efficiency according to the luminous power of the lamp body 100; for example, when the lamp body 100 is running at maximum power, multiple solenoid valves are controlled to open.

[0038] like Figures 1 to 3 As shown, in some embodiments, one end of the cooling pipe 320 is connected to the bottom of the liquid storage tank 310 to facilitate the flow of coolant in the second chamber 3112 to the cooling pipe 320; a water pump is provided on the cooling pipe 320 to drive the fluid flow in the cooling pipe 320; driven by the water pump, the coolant flows into the cooling pipe 320 and flows in the cooling pipe 320 to cool the lamp body 100.

[0039] like Figure 2As shown, in some embodiments, the top of the liquid storage tank 310 is provided with a water inlet 313 and a feed inlet 314. The water inlet 313 connects to the first chamber 3111, and the feed inlet 314 connects to the second chamber 3112. The water inlet 313 is located at the top of the liquid storage tank 310 to facilitate the addition of water to the first chamber 3111 while preventing water in the first chamber 3111 from overflowing through the water inlet 313. A first plug can be provided at the water inlet 313 to seal the water inlet 313 after water is added, preventing other impurities from entering the first chamber 3111. The feed inlet 314 is located at the top of the liquid storage tank 310 to facilitate the addition of coolant to the second chamber 3112 while preventing coolant in the second chamber 3112 from overflowing through the feed inlet 314. A second plug can be provided at the feed inlet 314 to seal the feed inlet 314 after coolant is added, preventing other impurities from entering the second chamber 3112. Both the first plug and the second plug are made of silicone.

[0040] like Figure 2 As shown, in some embodiments, the liquid storage tank 310 is provided with a return port 315 and a waste liquid chamber 316. The return port 315 is connected to the waste liquid chamber 316, which is used to recover the coolant after heat exchange. A waste liquid outlet 3161 can be provided at the top of the waste liquid chamber 316. The top of the waste liquid chamber 316 is connected to the top of the first chamber 3111, so that the air pressure in the liquid storage tank 310 is kept balanced, and the possibility of the coolant in the waste liquid chamber 316 flowing into the first chamber 3111 is reduced. One end of the cooling pipe 320 is connected to the second chamber 3112, and the other end is connected to the return port 315, so that the cooled coolant flows back into the first chamber 3111. The bottom of the liquid storage tank 310 has a first drain port connected to the first chamber 3111 and a second drain port connected to the second chamber 3112, which facilitates the discharge of waste liquid after use.

[0041] like Figures 1 to 3 As shown, in some embodiments, the cooling pipe 320 includes multiple connecting sections 321 and multiple cooling sections 322. The cooling sections 322 are arranged along the height direction of the lamp body 100 to uniformly dissipate heat at various positions along the height direction of the lamp body 100, preventing local overheating of the lamp body 100 and thus improving the overall heat dissipation uniformity of the lamp body 100. The connecting sections 321 connect two adjacent cooling sections 322, allowing coolant to flow into each cooling section 322 to dissipate heat at different positions of the lamp body 100. The cooling sections 322 are attached to the outer surface of the lamp body 100 to improve the heat exchange effect between the cooling sections 322 and the lamp body 100, thereby improving the cooling efficiency.

[0042] The coolant is ammonium nitrate crystals. When ammonium nitrate crystals dissolve in water, they absorb heat efficiently to form a coolant. When the lamp body 100 is working, it will emit a large amount of heat. At this time, the through hole 3121 is opened by controlling the solenoid valve. The water in the first chamber 3111 and the ammonium nitrate crystals in the second chamber 3112 react and absorb a large amount of heat to form a coolant. The large amount of heat generated by the lamp body 100 during operation is absorbed, thereby achieving the cooling effect.

[0043] like Figure 1 As shown, in some embodiments, the bracket 200 includes a base 210 and two support arms 220 connected to the base 210, with the lamp body 100 rotatably connected to the support arms 220; a cooling fan 211 is provided on the base 210; the base 210 bears the weight of each component of the lamp body 100, and the support arms 220 further support the lamp body 100, and the support arms 220 are rotatably connected to the lamp body 100, allowing the lamp body 100 to rotate in a horizontal or vertical direction; the base 210 is provided with the cooling fan 211. The cooling fan 211 can accelerate heat dissipation and further enhance the heat dissipation effect of the lamp body 100 during operation. Since the cooling component 300 is located on the outer periphery of the lamp body 100, the area below the lamp body 100 may not be cooled, resulting in localized overheating. If this continues for too long, it will affect the normal use of the lamp body 100. By placing the cooling fan 211 on the base 210, it creates an active airflow under the lamp body 100 to blow away the hot air from the lamp body 100, thus preventing heat accumulation from affecting the bracket 200 itself and the surrounding environment.

[0044] like Figure 1 As shown, in some embodiments, a drive unit is provided on the bracket 200; the output shaft of the drive unit is connected to the lamp body 100 and is used to control the rotation of the lamp body 100 relative to the bracket 200; when the drive unit drives the lamp body 100 to work, it can rotate so that the light can illuminate more areas and achieve more dynamic and flexible light effect changes; generally, the drive unit is a motor.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
