Description

Technical Field

[0001] The present application relates to the technical field of stage lighting equipment, and in particular to a lighting equipment for creating stage effects. Background Art

[0002] Lighting is the main means of stage art modeling. It uses lighting, slides and control systems to achieve changes in light color to create a sense of space and time, thereby achieving the purpose of displaying the environment, rendering the atmosphere and highlighting the central characters. Among them, lighting is an important part of the stage performance space.

[0003] Among them, spotlights are one of the important components of stage lighting. They can irradiate a narrow beam of strong light into a selected small area, and are an important means to highlight the central figure. However, due to the high-power usage requirements of spotlights, the heat generated during use is much greater than the heat it radiates to the outside, which causes the temperature inside the spotlight to rise sharply in a short period of time, making it impossible to operate stably and reliably for a long time. At the same time, the high temperature inside the spotlight also accelerates the aging and damage of its internal electrical components, seriously affecting the service life of the spotlight, and its stability and reliability are poor.

[0004] Therefore, there is an urgent need for a spotlight component for creating a stage effect to solve the defects of the above-mentioned existing spotlights in actual use. Summary of the invention

[0005] The present application proposes a lighting device for creating stage effects, which can use the movement of the spotlight during tracking rotation to perform auxiliary heat dissipation treatment on the inside, thereby preventing the internal temperature from being too high during long-term use. At the same time, it reduces the aging speed and damage rate of the electrical components inside the spotlight and extends its service life. It is used to solve the problem that due to the high-power use requirements of the spotlight, the heat generated during use is much greater than the heat dissipated to the outside, which causes the temperature inside the spotlight to rise sharply in a short period of time and cannot operate stably and reliably for a long time. At the same time, the high temperature inside the spotlight also accelerates the aging and damage of the internal electrical components, seriously affecting the service life of the spotlight.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a lighting equipment for creating stage effects, including a spotlight, wherein a reducer is provided inside the spotlight, and an output shaft is provided inside the reducer to form a transmission connection with the spotlight, and the two ends of the transmission shaft inside the reducer extend to the two sides outside the spotlight respectively, and are movably sleeved with the bottom end of a suspension whose top is fixedly mounted on a rotating device, and a driving motor that is transmission-connected to one end of the reducer is fixedly mounted on one side of the suspension, a movable sleeve is movably sleeved in the middle of the outer surface of the spotlight, and an elastic component is provided on the outer surface of the movable sleeve, and a transmission connection is formed with the left side of the outer surface of the spotlight through the elastic component, and a group of elliptical protrusions are fixedly sleeved at both ends of the outer surface of the reducer transmission shaft and located on the inner side of the suspension, and the two groups of protrusions are respectively in sliding friction contact with the linkage blocks fixedly mounted on the front and rear sides of the left end of the movable sleeve.

[0007] Furthermore, an annular groove is provided in the middle of the outer surface of the spotlight, and an annular protrusion is provided on the right side of the inner wall of the movable sleeve, thereby forming a piston structure in the inner cavity of the movable sleeve. At the same time, an air inlet hole formed by a one-way valve is provided on the right side of the outer surface of the movable sleeve, and an inner annular groove connected to the movable sleeve piston structure through the one-way valve is provided inside the spotlight, and the inner annular groove is connected to the external atmosphere through an exhaust hole arranged on the left side inside the spotlight.

[0008] Furthermore, the one-way valve connection point between the piston structure formed by the movable sleeve and the inner ring groove is located at the left end of the inner ring groove, and the distance from the left end of the inner ring groove to the inner side of the annular protrusion on the movable sleeve is greater than the length difference between the long side and the short side of the elliptical structure of the protrusion.

[0009] Furthermore, a local circular groove having a diameter equal to the length of the short side of the elliptical structure of the protrusion is formed at the end of the linkage block, thereby effectively increasing the adaptability between the linkage block and the protrusion.

[0010] Furthermore, the transmission ratio between the transmission shaft and the output shaft on the reducer is greater than, and when the drive motor is started to trigger the reducer to adjust the projection area of ​​the narrow beam of strong light on the spotlight, the number of rotations of the protrusion on the output shaft is effectively increased, and the frequency and amplitude of the reciprocating movement of the movable sleeve to the left and right are increased, so that the air flow rate circulating in the inner ring groove is increased, and more heat is discharged through the exhaust hole.

[0011] Furthermore, the interior of the spotlight is provided with heat-conducting fins extending into the inner ring groove, thereby effectively increasing the heat conduction efficiency between the spotlight and the air in the inner ring groove, and isolating the electrical components inside the spotlight from the inner ring groove.

[0012] Furthermore, a sealing gasket is provided on the inner wall of the annular protrusion on the movable sleeve to increase the sealing between the annular protrusion on the movable sleeve and the annular groove on the spotlight, and prevent air leakage during the process of squeezing air.

The two groups of protrusions 5 are in sliding and frictional contact with the linkage blocks 6 fixedly installed on the front and rear sides of the left end of the movable sleeve 7, and then when the protrusion 5 rotates with the transmission shaft, under the elastic force of the elastic component 8, the movable sleeve 7 can be forced to move back and forth left and right due to the length difference between the long side and the short side of the protrusion 5, generating air flow to increase the heat dissipation effect of the spotlight 1.

[0025] like Figure 4 , Figure 5As shown, in the present technical scheme, an annular groove is provided in the middle of the outer surface of the spotlight 1, and an annular protrusion is provided on the right side of the inner wall of the movable sleeve 7, thereby forming a piston structure in the inner cavity of the movable sleeve 7.

[0026] like Figure 4 As shown, in the present technical solution, the one-way valve connection point between the piston structure formed by the movable sleeve 7 and the inner ring groove 9 is located at the left end of the inner ring groove 9, and the distance from the left end of the inner ring groove 9 to the inner side of the annular protrusion on the movable sleeve 7 is greater than the length difference between the long side and the short side of the elliptical structure of the protrusion 5, thereby effectively avoiding the movable sleeve 7 from causing blockage of the one-way valve connected to the inner ring groove 9 during the process of reciprocating movement left and right.

[0027] like Figure 5 As shown, in the present technical solution, a local circular groove having a diameter the same as the short side length of the elliptical structure of the protrusion 5 is provided at the end of the linkage block 6, thereby effectively increasing the fit between the linkage block 6 and the protrusion 5, and effectively reducing the friction resistance of the protrusion 5 during the process of rotating and extruding the linkage block 6, thereby reducing the friction loss therebetween.

[0028] like Figure 2 As shown, in the present technical solution, the transmission ratio between the transmission shaft and the output shaft on the reducer 2 is greater than 1, and when the drive motor 4 is started to trigger the reducer 2 to adjust the projection area of ​​the narrow beam of strong light on the spotlight 1, the number of rotations of the protrusion 5 on the output shaft is effectively increased, and the frequency and amplitude of the reciprocating movement of the movable sleeve 7 are increased, so that the air flow rate circulating in the inner ring groove 9 is increased, and more heat is discharged through the exhaust hole 10.

[0029] like Figure 4 As shown, in the present technical solution, the interior of the spotlight 1 is provided with heat-conducting fins 11 made of metal material and extending into the inner ring groove 9, thereby effectively increasing the heat conduction efficiency between the spotlight 1 and the air in the inner ring groove 9, and making the electrical components inside the spotlight 1 isolated from the inner ring groove 9, so that dust and other impurities in the air will not enter the interior and cause damage to the electrical components therein.

[0030] In the present technical solution, a sealing gasket is provided on the inner wall of the annular protrusion on the movable sleeve 7 to increase the sealing between the annular protrusion on the movable sleeve 7 and the annular groove on the spotlight 1, and no air leakage occurs during the air squeezing process, thereby effectively increasing the flow rate and flow intensity of air in the inner annular groove 9, and improving its auxiliary heat dissipation effect and efficiency for the spotlight 1.
