[0046] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] In the prior art high-power stage lights, a large amount of heat is generated when the light source is working, and the temperature of the area irradiated by the imaging focus is even higher. The stage light realizes the stroboscopic function by setting a stroboscopic film 20. In actual applications, the imaging focus of the light source falls on the stroboscopic film 20. Under the influence of long-term high temperature, the stroboscopic film 20 is prone to deformation, resulting in a jamming phenomenon when the stroboscopic film 20 rotates, seriously affecting the performance effect.

[0048] In view of the above problems, the present utility model provides a stroboscopic heat dissipation device, which can forcibly dissipate heat from the stroboscopic part 2 through the fan 3, prevent the stroboscopic part 2 from overheating, and avoid the problem that the stroboscopic part 2 is deformed and jammed during rotation.

[0049] The technical solutions of the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0050] Figure 1 is a schematic diagram of the closed state of the stroboscopic heat dissipation device shown in the embodiment of the present utility model;

[0051] Figure 2 is a schematic structural diagram of the stroboscopic heat dissipation device shown in the embodiment of the present utility model.

[0052] Please refer to Figure 1 and Figure 2 A stroboscopic heat dissipation device provided by an embodiment of the present utility model includes an optical part 1 for switching the light effect of the light;

[0053] A stroboscopic part 2, the stroboscopic part 2 is rotationally connected to the optical part 1 through a rotating shaft, and the stroboscopic part 2 is used for adjusting the output effect of the light effect of the light;

[0054] A heat dissipation assembly, including a fan 3 and a driving mechanism. Among them, the fan 3 is slidably matched with the optical part 1, the air outlet of the fan 3 faces the stroboscopic part 2, and the driving mechanism drives the fan 3 to move away from or close to the stroboscopic group;

[0055] A first rotating part 4 for driving the stroboscopic part 2 to rotate around the axis of the rotating shaft.

[0056] In the prior art, the stroboscopic part 2 can be closed and opened when rotating, so that it can block or cut the light effect of the light to realize the stroboscopic function of the stage light. Generally, the stroboscopic function can be divided into synchronous stroboscopy, asynchronous stroboscopy and random stroboscopy. In the specific embodiment of the present utility model, the stroboscopic heat dissipation device has the same stroboscopic function.

[0057] When applying this stroboscopic heat dissipation device, it is installed in the internal space of the stage light. The light beam of the light source of the stage light outputs corresponding lighting effects through the optical part 1. After starting the stage light, the user can, according to their actual needs, through the preset control program of the stage light, control the first rotating part 4 to drive the stroboscopic part 2 to rotate with preset operating parameters to achieve opening and closing. At this time, the state of the stroboscopic heat dissipation device can be as shown in Figure 1 shown, so as to realize the current lighting effect and stroboscopic effect. After the stage light has been operating for a period of time, the imaging focus of the stage light stays on the stroboscopic part 2 for a longer and longer time, resulting in more and more heat accumulated in the stroboscopic part 2. In order to improve the use effect of the stage light, the inventor has set a fan 3 on the stroboscopic heat dissipation device to forcibly dissipate heat from the stroboscopic part 2, reduce the peak temperature of the stroboscopic part 2, and ensure that the heat inside the stroboscopic part 2 does not cause the stroboscopic part 2 to overheat and deform.

[0058] In a specific embodiment, the fan 3 of the above stroboscopic heat dissipation device is slidably arranged on the optical part 1;

[0059] The stroboscopic heat dissipation device further includes a driving part 5, and the driving part 5 is used to drive the fan 3 away from or close to the stroboscopic part 2.

[0060] In practical applications, the fan 3 can be started automatically after the stage light is started, or the temperature of the stroboscopic part 2 can be monitored by setting a corresponding temperature sensor. When the temperature of the stroboscopic part 2 reaches the threshold value, the fan 3 can be started to forcibly dissipate heat, and the output power of the fan 3 can be set according to the temperature information fed back by the current temperature sensor.

[0061] By setting the driving part 5, the fan 3 is driven to be close to or away from the stroboscopic part 2 to perform targeted forced heat dissipation on the stroboscopic part 2. In this embodiment, there are various ways to realize the fan 3 approaching or leaving the stroboscopic part 2. Taking the length direction of the stroboscopic part 2 as an example, the moving direction of the fan 3 can be parallel to the length direction of the stroboscopic part 2, or can form a certain angle with this length direction. Under the above movement modes, forced heat dissipation can be carried out on the stroboscopic part 2.

[0062] In a preferred embodiment, please refer to Figure 2 and Figure 3 , the moving direction of the fan 3 is perpendicular to the axis of the stroboscopic part 2.

[0063] When using the stage light, there may be occasions where the stroboscopic part 2 is not required, but the lighting effect output of the conventional function is required. In this case, the state of the stroboscopic heat dissipation device can be as shown in Figure 3As shown, in this state, the first rotating part 4 drives the stroboscopic part 2 to open and close, and the stroboscopic part 2 does not block or cut the light rays. The user can make different settings for the fan 3 and the driving mechanism according to specific usage situations, so that the fan 3 can approach and move away from the stroboscopic part 2 in a cyclic manner, thereby air-cooling the optical part 1 itself and the stage light, reducing the temperature of the internal space of the stage light, and extending the service life of each component of the stage light.

[0064] When the stroboscope of the stage light is started, the stroboscopic part 2 continuously opens and closes under the drive of the first rotating part 4, and the driving mechanism drives the fan 3 to approach the stroboscopic part 2 to forcibly dissipate heat from the stroboscopic part 2.

[0065] In a specific embodiment, please refer to Figure 4 , the stroboscopic part 2 of the above stroboscopic heat dissipation device includes two stroboscopic sheets 20. The first ends of the two stroboscopic sheets 20 are connected to the rotating shaft, and the second ends of the two stroboscopic sheets 20 are arranged crosswise so that the stroboscopic sheets 20 can overlap and cut the light effect of the light.

[0066] By setting the fan 3 and using the fan 3 to forcibly dissipate heat from the stroboscopic part 2, the peak temperature of the stroboscopic part 2 is reduced, so that the material of the stroboscopic sheet 20 can be unrestricted. It can be plastic or metal, enabling it to use materials with lower costs to manufacture the stroboscopic sheet 20, and generally reducing the performance requirements of the stroboscopic sheet 20.

[0067] In this embodiment, the included angle formed by the crosswise arrangement of the two stroboscopic sheets 20 can be freely set according to the length and shape of the stroboscopic sheets 20.

[0068] In a specific embodiment, notches 21 are provided on the opposite side walls of the two stroboscopic sheets 20 of the above stroboscopic heat dissipation device. The notches 21 are used to form a pattern light effect. The notches 21 can be set as circular arcs, serrations, and wavy shapes. When the light beam of the light source of the stage light forms a light effect through the optical part 1, such as a circular yellow light spot, when the notch 21 (for example, serrated) of the stroboscopic sheet 20 is located above the light exit hole 110, the circular yellow light spot can be cut into a yellow light spot with an arc and serrated shape on the outer periphery. Therefore, when synchronous stroboscopy, asynchronous stroboscopy, or random stroboscopy is obtained through the stroboscopic sheet 20, various different stroboscopic effects can be obtained.

[0069] In a specific embodiment, in order to improve the heat dissipation effect of the stroboscopic sheet 20, on the basis of the above specific embodiment, please refer to Figure 5 , the stroboscopic sheet 20 of the above stroboscopic heat dissipation device has opposite first end faces and second end faces. The first end face faces away from the optical part 1, and a plurality of fins 22 are provided on the first end face. The plurality of fins 22 are parallel to the air outlet direction and are arranged at intervals;

[0070] A limiting post 17 is further provided on the optical part 1, a limiting groove 23 is provided at the first end of the stroboscopic sheet 20, and the limiting post 17 is accommodated on the limiting groove 23.

[0071] Fins 22 are provided on the stroboscopic sheet 20. When the air flow conveyed by the blower 3 passes through the surface of the fins 22, a large amount of heat can be carried. Moreover, the arrangement mode of the fins 22 is parallel to the air outlet direction, which can enable the air to flow smoothly through the surface of the fins 22, effectively improving the overall heat dissipation effect. By providing the fins 22 on the stroboscopic sheet 20, the heat transfer area is increased, and the temperature of the stroboscopic sheet 20 can be further reduced.

[0072] It should be noted that the distances between several spaced fins 22 can be set to be equal, or can be set to be unequal. The lengths of several fins 22 can also be set to be long and short, so as to facilitate the air to flow through the fins 22, avoid the air staying on the fins 22 or being blocked too much by the fins 22. In this setting, the heat exchange performance of the blower 3 for the fins 22 can be improved, and the heat exchange effect of the fins 22 can be improved.

[0073] Among them, the connection mode between several fins 22 and the stroboscopic sheet 20 can be set by an integral molding process. When the material used is metal, a metal injection molding process can be adopted. When the material used is plastic, an injection molding integral molding process can be adopted.

[0074] It should be noted that the stroboscopic sheet 20 in this embodiment can also be made of a glass material. An opaque ink layer is screen-printed on the glass material, and then the fins 22 made of a metal material are bonded to the glass through a high-temperature resistant adhesive.

[0075] By respectively providing a limiting groove 23 and a limiting post 17 on the stroboscopic sheet 20 and the bottom plate 11, it can be avoided that the stroboscopic sheet 20 impacts the stage light due to a failure of the first rotating part 4.

[0076] In a specific implementation manner, the optical part 1 of the above stroboscopic heat dissipation device includes a bottom plate 11, a pattern disk 12, a color disk 13 and two second rotating parts 14;

[0077] A light outlet hole 110 is provided on the bottom plate 11; several pattern pieces 120 are provided on the pattern disk 12 and are arranged in a ring around the axis of the pattern disk 12;

[0078] Several color pieces 130 are provided on the color disk 13 and are arranged in a ring around the axis of the color disk 13;

[0079] The pattern disk 12, the color disk 13 and the stroboscopic part 2 are arranged in sequence along the irradiation direction of the stage light source. The pattern disk 12 and the color disk 13 partially overlap, and the overlapping area is opposite to the light outlet hole 110;

[0080] The two second rotating parts 14 respectively drive the pattern disc 12 and the color disc 13 to rotate around their own axes.

[0081] Specifically, the light source in the stage light irradiates the light beam through the light outlet hole 110 into the pattern disc 12 and the color disc 13. After the light beam passes through the pattern disc 12 and the color disc 13, various types of lighting effects are formed. The stroboscopic part 2 arranged above the color disc 13 is continuously opened and closed under the drive of the first rotating part 4. When it is necessary to switch the lighting effects, the pattern disc 12 and the color disc 13 are respectively rotated by the second rotating part 14, so that the corresponding pattern pieces 120 and color pieces 130 are aligned with the light outlet hole 110.

[0082] It should be noted that the stage light can also directly realize the output of conventional lighting effects through the pattern disc 12 and the color disc 13. During specific operation, the first rotating part 4 opens and closes the stroboscopic part 2, so that the second end of the stroboscopic piece 20 is far away from the light outlet hole 110 to achieve this.

[0083] The number of pattern pieces 120 arranged on the pattern disc 12 and the number of color pieces 130 arranged on the color disc 13 can be freely set according to the actual situation, and there is no unique limitation here.

[0084] In a specific embodiment, the optical part 1 of the above stroboscopic heat dissipation device further includes a first sensor 15 and a second sensor 16. The first sensor 15 is located between the pattern disc 12 and the bottom plate 11 and is used to collect the rotation amplitude information of the pattern disc 12; the second sensor 16 is located between the color disc 13 and the bottom plate 11 and is used to collect the rotation amplitude information of the color disc 13.

[0085] Preferably, the first sensor 15 and the second sensor 16 are magnetic sensors.

[0086] In a specific embodiment, an opening groove 111 is formed on the bottom plate 11 of the above stroboscopic heat dissipation device;

[0087] The driving part 5 includes two parallel guide rails 50, a synchronous belt 51, a first stepping motor 52, a synchronous gear and a driven wheel; sliders are arranged on the guide rails 50; both ends of the guide rails 50 are connected to the bottom plate 11 through supports 56; both ends of the synchronous belt 51 are respectively meshed and connected with the synchronous gear and the driven wheel, the first stepping motor 52 is connected to the synchronous gear, and the synchronous belt 51 is connected to the blower 3;

[0088] The blower 3 is connected to the slider 55 and is located in the opening groove 111.

[0089] The opening slot 111 is provided on the bottom plate 11, so as to optimize the structural layout of the strobe heat dissipation device so that it can be arranged in a narrow space of a stage light.

[0090] A stepper motor is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of pulses input, and the rotation speed is proportional to the pulse frequency. Therefore, the stepper motor can accurately control the rotation amplitude of the strobe sheet 20 and can accurately position the stroke of the two strobe sheets 20 to achieve various types of strobe effects.

[0091] In a specific embodiment, the above-mentioned stroboscopic heat dissipation device further includes two third sensors 6, which are arranged at intervals on the optical part 1 along the axis of the guide rail 50, and the third sensors 6 are used to collect position information of the fan 3;

[0092] The fan 3 includes an air guide housing 30, a wind wheel 31 and a motor. The wind wheel 31 is arranged in the air guide housing 30 and is transmission-connected to the motor. The air guide housing 30 is provided with an air inlet and an air outlet.

[0093] The first rotating part 4 includes a second stepping motor 41 ; the second rotating part 14 includes a third stepping motor.

[0094] In this embodiment, the air inlet of the fan 3 can be arranged inside the stage light, or can be connected to the outside environment. When the air inlet of the fan 3 is connected to the outside environment, a filtering structure, such as foam, can be arranged inside the air guide shell 30 of the fan 3 to facilitate the introduction of air and filter dust, hair and other dirt in the air, so as to prevent dirt from contaminating the optical part 1 and affecting the actual output effect of the light effect.

[0095] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Through the first stepping motor 52, the synchronous belt 51 and the synchronous teeth 53, linear reciprocating driving is performed, and the opening and closing, and closing angles of the stroboscopic sheet 20 are monitored in real time. Through a software program, the opening and closing angle position of the stroboscopic sheet 20 is calculated to adjust the air outlet angle of the blower 3 and increase or decrease the speed of the blower 3 according to a preset program. The present utility model solves the problem of the stroboscopic sheet 20 deforming at high temperature, and can achieve energy saving and noise reduction in the idle state. While performing after-sales maintenance, it also reduces the convenience of maintaining and using existing products, effectively reducing the product failure rate and the cost of installation time.
