Description

TECHNICAL FIELD

[0001] The utility model relates to a stage lamp's ventilation and heat dissipation structure for performance or entertainment on stage, outdoor performance etc. BACKGROUND

[0002] With the rapid development of stage lighting technology, the development of computer head lamp puts forward higher and higher technical requirements to the field of stage lighting, and the controllable brightness of light is also higher and higher. In order to improve the brightness, the power of the light source used is also larger and larger, and the arrangement of the light source is more and more dense. Most of the head dyeing lamps on the market adopt single-color or multi-color LED cold light source, and the service life and luminous efficiency of LED light source are greatly affected by temperature, so how to reasonably design the heat dissipation of stage lamp is particularly important.

[0003] At present, the head dyeing lamps with multiple LED lamp beads dispersed arrangement on the market generally have problems of insufficient rated power and insufficient brightness, and the fundamental reason is that high-power LED light source is adopted but the heat dissipation system is not reasonably designed, for example, a high-power fan is usually used for heat dissipation, the heat dissipation range is small, the motor is independently installed, which leads to delayed heat dissipation of the motor, and the cold and hot air ducts are mixed with each other, etc. These factors lead to full power and high brightness when the light is turned on and the motor is cold, but when the temperature gradually rises due to the heat generated by the light source, in order to protect the light source from damage, the light source power is reduced, so the brightness also decreases. CONTENT OF THE UTILITY MODEL

The air guide plate has multiple air inlets that lead to the radiator. Multiple cooling fans are included, with each air inlet corresponding to a cooling fan. The cooling fans are mounted on the bottom surface of the air guide plate and aligned with the air inlets. An air outlet is also provided in the air guide plate, aligned with the center lens focusing motor. An air guide shroud is provided on the bottom surface of the air guide plate, separating the air outlet channel of the center lens focusing motor from the air inlet channel of the radiator. An air outlet and an air inlet are provided on the housing; the air outlet connects to the radiator, and the air inlet connects to the cooling fans.

[0006] Furthermore, a motor mounting hole is provided in the radiator, and the outer lens focusing motor and the middle lens focusing motor are respectively installed in the motor mounting hole to form a mounting structure embedded in the radiator.

[0007] Furthermore, the air inlet includes four air inlets, which are arranged in a uniform rectangular array in the air guide plate, avoiding the outer lens focusing motor and the middle lens focusing motor. The four cooling fans are evenly arranged on the bottom surface of the air guide plate.

[0008] Furthermore, the housing includes a tail cap and a front ring, the front ring being fixedly attached to the tail cap to house the outer lens assembly, and the middle lens assembly being embedded in the outer lens assembly and extending a portion from the center of the outer lens assembly.

[0009] Furthermore, the heatsink is located within the space covered by the tail cover, and the air outlet includes multiple side air outlets.

[0012] This invention employs a method of evenly distributing multiple small cooling fans, which is more precise, covers a wider area, and generates greater air pressure than using a single large cooling fan to target areas with concentrated heat. This accelerates airflow, allowing heat to be transferred to the air more quickly and dissipating heat more promptly. Furthermore, the use of multiple cooling fans in conjunction with air guide plates, air guide covers, and a tail cap isolates the inlet cool air channel from the outlet hot air channel, resolving the problem of localized heat accumulation. The hot and cold air do not mix or interfere with each other, thus improving heat dissipation efficiency and effectiveness. Attached Figure Description

Detailed Implementation

[0021] In this embodiment, refer to Figures 1-7The stage lighting ventilation and heat dissipation structure includes a main unit 1, a support arm assembly 2, and a lamp body assembly 3. The support arm assembly 2 is horizontally rotated and assembled with the main unit 1, and the lamp body assembly 3 is vertically rotated and assembled with the support arm assembly 2. The lamp body assembly 3 includes a housing, a light source assembly, a heat dissipation assembly 32, a center lens assembly 33, and an outer lens assembly 34. The heat dissipation assembly 32 includes a cooling fan 322 and a heat sink 326. The light source assembly uses multiple high-power LED beads, which are mounted on the heat sink 326. The center lens assembly 33 is connected to a center lens focusing motor 325, and the outer lens assembly 34 is connected to an outer lens focusing motor 324. A guide plate 323 is installed on the bottom surface of the heat sink 326, and multiple... There are multiple air inlets 328 leading to the radiator 326. Each air inlet 328 corresponds to one radiator 322. The radiator 322 is installed on the bottom surface of the air guide plate 323 and aligned with the air inlet 328 to blow cool air onto the radiator 326. An air outlet 329 is also provided in the air guide plate 323, which is aligned with the center lens focusing motor 325. An air guide cover 321 is provided on the bottom surface of the air guide plate 323 to separate the air outlet channel of the center lens focusing motor 325 from the air inlet channel of the radiator 326. An air outlet and an air inlet 312 are provided on the housing. The air outlet is connected to the radiator 326, and the air inlet 312 is connected to the radiator 322.

[0022] A motor mounting hole 327 is provided in the heat sink 326. The outer lens focusing motor 324 and the middle lens focusing motor 325 are respectively installed in the motor mounting hole 327 to form a mounting structure embedded in the heat sink 326. This eliminates the need for the outer lens focusing motor 324 and the middle lens focusing motor 325 to occupy additional space, thereby helping to reduce the size of the entire lamp assembly 3.

[0023] The air inlet 328 includes four air inlets 328, which are arranged in a uniform rectangular array in the air guide plate 323, avoiding the outer lens focusing motor 324 and the middle lens focusing motor 325. The four cooling fans 322 are evenly arranged on the bottom surface of the air guide plate 323.

[0024] The housing includes a tail cap 31 and a front ring 35. The front ring 35 is fixedly attached to the tail cap 31 to house the outer lens assembly 34. The middle lens assembly 33 is embedded in the outer lens assembly 34 and extends a portion from the center of the outer lens assembly 34.

[0025] The heat sink 326 is located within the space covered by the tail cover 31. The air outlet 3 includes multiple side air outlets 311, each located on the upper periphery of the tail cover 31 close to the side of the heat sink 326, thus enabling rapid dissipation of heat from the heat sink 326. The air inlet 312 is located on the lower periphery of the tail cover 31 close to the cooling fan 322. Each cooling fan 322 corresponds to one air inlet 312, allowing cool air from the outside to be drawn in and supplied to the cooling fan 322 over the shortest possible distance.

[0026] The air outlet also includes a bottom air outlet 313 located on the bottom surface of the tail cover 31. The bottom air outlet 313 is connected to the air guide shroud 321, and the bottom end of the air guide shroud 321 is close to the bottom surface of the tail cover 31. The heat generated by the center lens focusing motor 325 during operation will be discharged to the outside through the air outlet 329, the air guide shroud 321 and the bottom air outlet 313 in sequence, avoiding interference with the cold air channel where the cooling fan 322 is located.

[0027] The outer lens assembly 34 is connected to two outer lens focusing motors 324, and the middle lens assembly 33 is connected to one middle lens focusing motor 325; the heat sink 326 is provided with three motor mounting holes 327, the middle lens focusing motor 325 is installed in the middle motor mounting hole 327, and the outer lens focusing motors 324 are installed in the motor mounting holes 327 on both sides, with each motor separated from the others; the air outlet 329 is located in the middle of the air guide plate 323 to be aligned with the middle lens focusing motor 325.

[0028] The heat generated by the light source components is transferred to the fins of the heat sink 326. When each cooling fan 322 is working, cool air enters from the corresponding air inlets 312 on the tail cover 31, and then blows air towards the heat sink 326 through the cooling fans 322, flowing towards the fins of the heat sink 326. After passing through the fins of the heat sink 326, the airflow flows into the outside air from the corresponding side air outlets 311. A portion of the cool air enters the fins of the heat sink 326 and flows vertically. The upper portion of the hot airflow flows into the outside air from the side air outlets 311 on the tail cover 31, while the lower portion of the hot airflow passes through the fins of the heat sink 326 to the middle position of the heat sink 326, and then flows in the opposite direction from the air outlet 329 in the middle of the air guide plate 323 into the air guide shroud 321. After passing through the air guide shroud 321, it reaches the outside air through the bottom air outlet 313. Meanwhile, the heat generated by the external lens focusing motor 324 during operation flows to the outside through the air guide shroud 321, solving the problem of heat accumulation inside the heat sink 326 and uneven heat distribution at different locations, thus ensuring that the high-power LED beads are in a uniform and balanced heat dissipation working state.

[0029] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
