Description

[0002] In the field of stage lighting, LED lamps have gradually replaced traditional lamps and become the mainstream due to their advantages such as high brightness, long life, and low power consumption. However, as the power of LED lamps continues to increase, their heat generation also increases, which places higher demands on the heat dissipation performance of LED lamps. Especially in stage performances, where lighting effects need to be frequently changed, the angle adjustment of the lamps and the rapid heat dissipation become key issues.

However, this method has drawbacks such as low heat dissipation efficiency, high noise levels, and dust accumulation, making it difficult to meet the cooling requirements of high-power LED fixtures. Furthermore, during the use of outdoor stage lighting equipment, rainwater and dust are inevitably present.

[0043] It is worth noting that the liquid cooling heat dissipation component 5 includes a cylindrical cooling shell 501, a coolant box 502, an annular partition 503, a guide hole 504, a piston cylinder 505, a liquid inlet pipe 506, a liquid discharge pipe 507 and other structures.

[0044] The cylindrical cooling shell 501 is fixedly connected to the inner wall of the spotlight tube 4 to form a circulating cooling chamber 515 with the spotlight tube 4. Several heat-conducting aluminum rods 516 are fixedly connected to the end of the cylindrical cooling shell 501 to transfer heat to the inside of the lamp cover 6.

[0045] It should be noted that the coolant box 502 is fixedly mounted on the surface of the supporting base plate 3, and the interior is used to store coolant. A semiconductor refrigeration plate 511 is fixedly embedded on the surface of the coolant box 502 to reduce the temperature of the coolant. A central baffle 510 is fixed on the inner wall of the coolant box 502, and the ports of the liquid inlet hose 523 and the liquid discharge hose 524 are symmetrically distributed on both sides thereof.

[0046] It should be noted that the annular partition 503 is fixedly connected between the outer surface of the cylindrical cooling shell 501 and the inner wall of the spotlight tube 4, and the surface thereof is evenly provided with guide holes 504 for the circulation of the cooling liquid.

[0047] It should be noted that the piston cylinder 505 is fixedly connected to the left and right sides of the rotating base 202, and a liquid inlet pipe 506 and a liquid discharge pipe 507 are fixedly embedded on the top thereof. A one-way liquid inlet valve 508 and a one-way liquid discharge valve 509 are fixed on the surface of the liquid inlet pipe 506 and the liquid discharge pipe 507 respectively to ensure the one-way flow of the coolant. A liquid inlet hose 523 and a liquid discharge hose 524 are fixed on the top ends of the liquid inlet pipe 506 and the liquid discharge pipe 507 respectively, extending to the interior of the coolant box 502.

[0048] It should be noted that the first circulation conduit 513 and the second circulation conduit 514 are fixedly embedded in the front and rear surfaces of the cooling liquid box 502 respectively, and the ends away from the cooling liquid box 502 extend into the interior of the circulation cooling cavity 515 for the circulation of the cooling liquid.

[0049] It should be noted that the semiconductor cooling fin 511 is fixedly embedded in the lower surface of the coolant box 502, with its cooling surface located inside the coolant box 502, for reducing the temperature of the coolant. The cooling fan 512 is fixedly mounted in the heat dissipation mounting hole on the lower surface of the support base 3, with its air inlet corresponding to the heat dissipation end of the semiconductor cooling fin 511, for dissipating the heat generated by the semiconductor cooling fin 511.

[0050] Working principle: When the LED lamp starts working, it generates a lot of heat. At this time, the liquid cooling component 5 starts working. The coolant is cooled by the semiconductor cooling plate 511 in the coolant box 502 and then enters the piston cylinder 505 through the liquid inlet pipe 506 and the liquid inlet hose 523.

[0051] As the spotlight tube 4 rotates driven by the multi-angle adjustment mechanism 2, the piston disc 521 reciprocates within the piston tube 505. When the support shaft 203 drives the linkage pull rod 522 downward, it also drives the piston disc 521 downward, creating a negative pressure inside the piston tube 505. This draws coolant from the circulating cooling chamber 515 into the piston tube 505 through the first circulating liquid conduit 513 and the liquid inlet hose 523. When the piston disc 521 returns upward, the coolant is fed into the other end of the circulating cooling chamber 515 through the drain hose 524 and the second circulating liquid conduit 514, causing the coolant to circulate within the circulating cooling chamber 515 formed between the cylindrical cooling shell 501 and the spotlight tube 4, absorbing and removing heat generated by the LED lamp. The heat-conducting aluminum rod 516 conducts heat from the circulating cooling chamber 515 to the interior of the lamp holder cover 6, further expanding the heat dissipation area.

[0052] As the semiconductor refrigeration chip 511 continues to work, the temperature of the coolant is reduced, and the heat dissipation effect is improved. The heat dissipation fan 512 is started to discharge the heat generated by the semiconductor refrigeration chip 511, ensuring that the semiconductor refrigeration chip 511 can continue to work efficiently.

[0053] When the angle of the spotlight tube 4 needs to be adjusted, the elevation angle can be adjusted by controlling the first adjustment motor 207 and the second adjustment motor 214. The first adjustment motor 207 is started to drive the driving screw 208 to rotate, and the driving screw 208 drives the driving plate 209 to move, thereby driving the moving plate 210 and the rack 211 to move. The rack 211 engages with the adjustment gear 206, driving the adjustment gear 206 to rotate. The adjustment gear 206 engages with the driven gear 204, driving the support shaft 203 to rotate, thereby achieving the elevation angle adjustment of the spotlight tube 4;

[0054] When the horizontal angle of the spotlight tube 4 is adjusted, the second adjustment motor 214 is started to drive the worm 215 to rotate. The worm 215 engages with the worm wheel 213 to drive the worm wheel 213 to rotate. The worm wheel 213 is fixed on the driving shaft of the rotating chassis 201, driving the rotating chassis 201 to rotate, thereby realizing the horizontal angle adjustment of the spotlight tube 4.

[0055] In summary, the automatic on-off stage lighting LED lamp of the present invention achieves precise control and efficient heat dissipation of stage lighting through an efficient liquid cooling system, intelligent angle adjustment function, innovative heat dissipation auxiliary design, and a compact and easy-to-maintain structural design, meeting the high requirements of stage performances for lighting effects.
