[0002] Generally, the heat dissipation system of a stage light includes a radiator and a heat dissipation fan. Two heat dissipation fans are arranged directly above the radiator to achieve heat dissipation inside the stage light. The technical defect brought about by the heat dissipation system structure is that part of the air volume of the heat dissipation fan will flow to the two sides of the radiator, thereby causing air volume loss, and further affecting the heat dissipation efficiency of the radiator.

[0003] In addition, there are two cooling fans, one of which draws cold air from the outside and blows it to the radiator for heat exchange, and the other draws hot air from the radiator after heat exchange and discharges it to the outside. The temperature of the cooling fins close to the side where cold air from the outside is extracted is lower than the temperature of the cooling fins close to the side where hot air is discharged, which makes the heat dissipation of the radiator uneven, resulting in malfunction of electronic components inside the lamp due to overheating.

[0024] It should be noted that, in the absence of conflict, the embodiments in the present application and the features described in the embodiments may be combined with each other. The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0025] As attached Figure 1 To Attachment Figure 6 As shown, a heat dissipation system for a stage lamp includes a shell 1, in which a lamp board 2 and a heat dissipation device for dissipating heat to the lamp board 2 are arranged in sequence from bottom to top in the shell 1, the heat dissipation device includes a heat dissipation fin group 3 and a wind driving member 4, the left and right ends of the heat dissipation fin group 3 are provided with a slope 31 which is gradually inclined from bottom to top toward the center position thereof, the air outlet of the wind driving member 4 is opposite to the slope 31, specifically, the wind driving member 4 is a heat dissipation fan, the slope angle range formed by the slope 31 and the horizontal plane is 30°-60°, the heat dissipation fan is arranged at a certain inclination angle, and the inclination angle is preferably the same as the angle of the slope angle, so that the air outlet of the wind driving member 4 is directly opposite to the slope 31, so that the air volume of the heat dissipation fan is maximized and directed to the heat dissipation fin group 3, and as much as possible, it is avoided that part of the air volume of the heat dissipation fan is blown to the two ends of the heat dissipation fin group 3 to cause loss. Compared with the prior art, the heat dissipation efficiency of the present invention is higher, which fully guarantees the normal operation of the equipment.

[0026] As attached Figure 6As shown, the heat dissipation fin group 3 is mainly composed of a plurality of heat dissipation fins arranged at intervals, and a heat dissipation channel 32 is formed between two adjacent heat dissipation fins. The heat dissipation channel 32 has a first channel opening 321 formed at the left end of the heat dissipation fin group 3 and a second channel opening 322 formed at the right end of the heat dissipation fin group 3. The first channel opening 321 is located on the slope 31 at the left end of the heat dissipation fin group 3, and the second channel opening 322 is located on the slope 31 at the right end of the heat dissipation fin group 3. The heat dissipation fan can drive the external cold air to enter the heat dissipation channel 32 from the first channel opening 321 or the second channel opening 322 for heat exchange, and the hot air after heat exchange comes out from the second channel opening 322 or the first channel opening 321 to accelerate the heat dissipation efficiency of the heat dissipation fin group 3.

[0027] As attached Figure 2 and attached Figure 4 It is shown that the shell 1 is provided with a first vent 11 and a second vent 12 that are connected to the outside world, the first channel opening 321 corresponds to the first vent 11, so that the first channel opening 321 is connected to the outside world through the first vent 11, and the second channel opening 322 corresponds to the second vent 12, so that the second channel opening 322 is connected to the outside world through the second vent 12. Furthermore, filters 100 are provided at the first vent 11 and the second vent 12, which can effectively remove particulate matter in the air.

[0028] As attached Figure 4 and attached Figure 5 As shown, the wind-repelling member 4 includes a first cooling fan group 41 arranged between the first channel opening 321 and the first vent 11 and a second cooling fan group 42 arranged between the second channel opening 322 and the second vent 12. The fan group is conducive to driving the external cold air to flow to the cooling fin group 3 and driving the hot air in the cooling fin group 3 to be discharged to the outside.

[0029] As attached Figure 3 To Attachment Figure 5As shown, the first cooling fan group 41 is provided with two, namely the first suction fan 411 and the first blowing fan 412, and a first isolation plate 51 is arranged between the first suction fan 411 and the first blowing fan 412; the second cooling fan group 42 is provided with two, namely the second suction fan 421 and the second blowing fan 422; a second isolation plate 52 is arranged between the second suction fan 421 and the second blowing fan 422, the first suction fan 411 corresponds to the second blowing fan 422 along the length direction of the heat dissipation channel 32, and the first blowing fan 412 corresponds to the second suction fan 421 along the length direction of the heat dissipation channel 32; further, the heat dissipation channel 32 formed between two adjacent heat sinks is divided into two parts, the heat dissipation channel 32 of the first part corresponds to the air outlet of the first suction fan 411 and the air outlet of the second blowing fan 422, and the heat dissipation channel 32 of the second part corresponds to the air outlet of the second suction fan 421 and the air outlet of the first blowing fan 412.

[0030] The heat dissipation system mainly includes two types of heat dissipation ducts:

[0031] One type of heat dissipation duct is to use a first suction fan 411 to suck in external cold air from the first vent 11, and guide it to the heat dissipation channel 32 of the first part through the first channel opening 321. After heat exchange, a second blowing fan 422 draws hot air from the second channel opening 322 and discharges it through the second vent 12.

[0032] Another type of heat dissipation duct is to use the second suction fan 421 to suck in the outside cold air from the second vent 12, and guide it to the second part of the heat dissipation channel 32 through the second channel opening 322. After heat exchange, the first blowing fan 412 draws hot air from the first channel opening 321 and discharges it through the first vent 11.

[0033] The wind directions of the heat dissipation air ducts in the above two methods are exactly opposite, thereby achieving uniform heat dissipation of the heat dissipation fin group 3.

[0034] As attached Figure 6 As shown, the left and right ends of the heat dissipation fin group 3 are both provided with grooves 30 opening upward, and the wind deflector 4 is fixedly arranged in the groove 30. The side of the groove 30 close to the center position of the heat dissipation fin group 3 is the slope 31, and the groove 30 is a V-shaped groove; the V-shaped groove is formed by a cutting process of several heat dissipation fins, which is convenient for placing the wind deflector 4 in the groove 30.

[0035] As attached Figure 5As shown, the shell 1 fixes the wind-repelling member 4 in the groove 30 through the fixing member 6, and the first isolation plate 51 and the second isolation plate 52 are fixed on the fixing member 6. The fixing member 6 is used to fix the first isolation plate 51, the second isolation plate 52 and the wind-repelling member 4 to make the structure more compact.

[0036] The invention also provides a stage lamp, which includes a lamp body, and the lamp body applies the heat dissipation system.
