Description

Technical Field

[0001] The utility model relates to the technical field of stage lights, in particular to a stage light that optimizes the heat dissipation performance of an optical effect component. Background Art

[0002] When a stage light is in use, a light beam is emitted by a light source and directly irradiates an optical effect element to produce an optical effect. Since it is directly irradiated by strong light, a large amount of heat accumulates on the optical element. It is necessary to use a special fan to blow air and use an air flow guide to guide the air flow to blow towards the optical effect element to achieve the purpose of cooling. However, there are various possibilities for the internal structure of the stage light to change with the application scenario and functional effect. Therefore, the structures of the fan and the air flow guide corresponding to each optical effect component also need to be redesigned in terms of structure and installation position with the change of the application scenario and functional effect.

[0003] Generally speaking, inside the stage light, the heat concentration positions of different optical effect components are also different from each other. Therefore, when different optical effect components are installed inside the stage light, it is necessary to specifically change the structure or installation position of the air flow guide to ensure that the air flow blown out by the heat dissipation fan can always be guided to the heat concentration position of the optical effect component. However, its disadvantage is that once the internal space of the stage light fixture is very compact, it is difficult to specifically set a suitable air flow guide inside the stage light according to different optical effect components, making it difficult for the guiding angle of the air flow guide to accurately guide the heat dissipation air flow to the heat concentration position of the optical effect component, resulting in the structure design of the air flow guide being unable to meet the requirement of guiding the heat dissipation air flow of the fan to the optical element at the optimal angle, thereby greatly reducing the heat dissipation effect of the stage light. Summary of the Utility Model

[0004] In order to solve the technical problems existing in the prior art to a certain extent as much as possible, the utility model provides a stage light that optimizes the heat dissipation performance of an optical effect component, which can ensure that the heat dissipation air flow blown out by the fan inside the stage light accurately blows to the heat concentration position of the optical effect component, and is more suitable for application in stage lights provided with different optical effect components.

[0005] A stage light that optimizes the heat dissipation performance of an optical effect component according to the utility model includes a lamp head housing, a light output lens, and a light source. The light source is arranged inside the lamp head housing. The light output lens covers the light output port of the lamp head housing and is on the optical path of the light source. An optical effect component is also arranged on the optical path between the light source and the light output lens. It further includes a wind cover and a fan.

[0006] The light source is sleeved inside the wind cover and a gap channel is formed between the light source and the inner side wall of the wind cover. The air flow output end of the fan is connected to the gap channel.

[0007] Among them, an air outlet allowing the light source to emit light outward, communicating with the gap channel and facing the optical effect component is formed on the air duct.

[0008] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, a toothed ring is arranged at the air outlet of the air duct;

[0009] Each tooth body of the toothed ring is arranged around the gap between the light source and the air duct.

[0010] The distance between each tooth body of the toothed ring is greater than 0.1 cm and less than 1 cm. This can not only ensure that the distance between teeth is long enough to divide the air flow passing through the air outlet into multiple strands, but also avoid excessive distance length, resulting in turbulence inside each air flow.

[0011] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, the optical effect component includes a pattern sheet, or a flame plate, or an aperture, or a cutter.

[0012] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, the side of the light source opposite to the air outlet is in heat transfer contact with the air duct to dissipate heat through the air duct to the outside.

[0013] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, the air duct is made of metal or plastic.

[0014] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, a heat dissipation component is provided on the lamp head housing, and the side of the air duct in contact with the light source is in heat transfer contact with the heat dissipation component.

[0015] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, a docking nozzle is arranged on the outer wall of the air duct;

[0016] One end of the docking nozzle accesses the inside of the air duct and communicates with the gap channel;

[0017] The other end of the docking nozzle is in butt joint communication with the air flow output end of the blower.

[0018] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, the blower is a flat blower;

[0019] The docking nozzle is arranged on the side of the air duct and is in linear butt joint communication with the air flow output port on the side of the blower.

[0020] For a stage light optimizing the heat dissipation performance of an optical effect component according to the present invention, the air duct is provided as the lamp core housing of the light source.

[0021] A stage light for optimizing the heat dissipation performance of an optical effect component according to the present utility model. A fixed substrate is provided inside the lamp head housing. A wind cover mounting position corresponding to the wind cover is provided on the fixed substrate, and the wind cover is fixedly sleeved inside the wind cover mounting position.

[0022] The stage light for optimizing the heat dissipation performance of an optical effect component of the present utility model adds a wind cover inside the lamp head housing of the stage light. At the same time, the light source is sleeved inside the wind cover and a gap channel is formed between the light source and the inner side wall of the wind cover. During installation, the air flow output end of the fan for heat dissipation inside the stage light is connected to the gap channel. Therefore, the heat dissipation air flow output by the fan can enter the gap channel inside the wind cover. In addition, an air outlet is provided on the wind cover. The air outlet not only allows the light source to emit light outward, but also communicates with the gap channel and faces the optical effect component. Therefore, after the heat dissipation air flow output by the fan enters the gap channel inside the wind cover, under the guidance of the air outlet, it can be further blown to the optical effect component inside the lamp head. Since the light source also emits light outward through the air outlet, at this time, the heat dissipation air flow blown out from the air outlet is adjacent to the light source and in the same direction as the light emitting direction of the light source. Thus, the position where the light source is concentratedly irradiated on the optical effect component (equivalent to the heat concentration position) can also be simultaneously concentratedly blown and cooled by the heat dissipation air flow. In this way, no matter how the layout structure of each optical effect component inside the stage light is changed and designed, as long as the optical path of the light beam emitted by the light source towards the optical effect component remains unchanged, there is no need to re-design the heat dissipation structure of the optical effect component, and the light beam irradiation direction cannot be blocked by components. It is the position where the optical effect component is most concentratedly heated. After being guided by the air outlet of the wind cover, the heat dissipation air flow is blown out along the light emitting direction of the light source, and can be directly blown to the heat concentration position of the optical effect component with the least loss, achieving a better cooling effect. Therefore, the technical solution of the present utility model can ensure that the heat dissipation air flow blown out by the fan inside the stage light is accurately blown to the heat concentration position of the optical effect component, and is more suitable for application in stage lights provided with different optical effect components.

[0035] As Figures 1 to 8As shown in the figure, a stage light that optimizes the heat dissipation performance of an optical effect component in this embodiment. The main structure of the stage light includes a lamp head housing 1, a light output lens 2, a light source 3, a wind cover 5, and a fan 6. The light source 3 is installed inside the lamp head housing 1. The light output lens 2 covers the light output port of the lamp head housing 1 and is on the optical path of the light source 3. Inside the lamp head housing 1, an optical effect component 4 is also installed on the optical path between the light source 3 and the light output lens 2. Optionally, the optical effect component 4 includes a pattern sheet, or a flame plate, or an atomizing sheet, or an aperture, or a cutter. The light source 3 is sleeved inside the wind cover 5, and a gap channel 51 is formed between the outer wall of the light source 3 and the inner side wall of the wind cover 5. Specifically, the gap channel 51 is an annular gap. The air flow output end of the fan 6 is connected to the gap channel 51. In addition, the wind cover 5 is provided with an air outlet 52 that allows the light source 3 to emit light outward, communicates with the gap channel 51, and faces the optical effect component 4.

[0036] The technical solution of the present utility model adds a wind cover 5 inside the lamp head housing 1 of the stage light. At the same time, the light source 3 is sleeved inside the wind cover 5 and a gap channel 51 is formed between the light source 3 and the inner side wall of the wind cover 5. During installation, the air flow output end of the fan 6 used for heat dissipation in the stage light is connected to the gap channel 51. Therefore, the heat dissipation air flow output by the fan 6 can enter the gap channel 51 inside the wind cover 5. In addition, the wind cover 5 is also provided with an air outlet 52. The air outlet 52 not only allows the light source 3 to emit light outward, but also communicates with the gap channel 51 and faces the optical effect component 4. Therefore, after the heat dissipation air flow output from the fan 6 enters the gap channel 51 inside the wind cover 5, under the guidance of the air outlet 52, it can be further blown to the optical effect component 4 inside the lamp head. Since the light source 3 also emits light outward through the air outlet 52, the heat dissipation air flow blown out from the air outlet 52 is adjacent to the light source and in the same direction as the light emission direction of the light source at this time. Thus, the position on the optical effect component 4 where the light source 3 is concentratedly irradiated (equivalent to the heat concentration position) can also be simultaneously blown and cooled intensively by the heat dissipation air flow. In this way, no matter how the arrangement structure of each optical effect component inside the stage light is changed and designed, as long as the optical path of the light beam emitted by the light source towards the optical effect component remains unchanged, there is no need to redesign the heat dissipation structure of the optical effect component, and the light beam irradiation direction cannot be blocked by components. It is the position where the optical effect component is most concentratedly heated. After being guided by the air outlet 52 of the wind cover 5, the heat dissipation air flow blows out along the light emission direction of the light source, and can directly blow to the heat concentration position of the optical effect component with the least loss, achieving a better cooling effect. Therefore, the technical solution of the present utility model can ensure that the heat dissipation air flow blown out by the fan inside the stage light accurately blows to the heat concentration position of the optical effect component, and is more suitable for application in stage lights provided with different optical effect components.

[0037] In one embodiment, further, a gear ring 53 is sleeved on the air outlet 52 of the air hood 5, and the teeth of the gear ring 53 are arranged in a circumferential pattern around the gap between the light source 3 and the air hood 5. The technical effect of this structure is that the circumferentially arranged teeth of the gear ring 53 can divide the annular gap channel 51 to a certain extent, restricting the instability during the air flow output within each compartment, making it difficult for the air flow to surge within the air hood 5, thus stabilizing the air flow and eliminating acoustic oscillations to reduce noise. Specifically, the distance between the teeth of the gear ring 53 is greater than 0.1 cm and less than 1 cm, which can ensure that the distance between the teeth is long enough to divide the air flow passing through the air outlet into multiple streams, and also avoid excessive distance, which may cause turbulence within each air flow stream.

[0038] Optionally, the gear ring 53 can be integrally formed on the air outlet 52 of the air hood 5.

[0039] In one embodiment, further, one side of the bottom of the light source 3 is in heat transfer contact with the air hood 5. Optionally, to improve the heat dissipation performance, the air hood 5 is made of metal or plastic. Therefore, after the bottom of the light source 3 contacts the air hood 5, it is convenient for the heat of the light source 3 to dissipate externally through the air hood 5, ensuring the normal external heat dissipation of the light source 3.

[0040] Preferably, the air hood 5 is made of copper or aluminum.

[0041] In one embodiment, a heat dissipation component 8 is installed at the bottom of the lamp head housing 1. The heat dissipation component 8 is a prior art, which mainly includes a plurality of heat dissipation fins and a heat transfer tube connected in series to each heat dissipation fin. The bottom side of the light source 3 is in heat transfer contact with the bottom side of the air hood 5 inside the air hood 5, and the outside of the bottom side of the air hood 5 is in heat transfer contact with the heat dissipation component 8. Therefore, after the air hood 5 absorbs the heat of the light source 3, it can further dissipate heat through the heat dissipation component 8 at the bottom, ensuring continuous cooling of the light source 3.

[0042] Regarding the connection structure between the air hood 5 and the fan 6, a docking nozzle 54 is integrally formed on the outer wall of the air hood 5. The inner end of the docking nozzle 54 accesses the inside of the air hood 5 and communicates with the gap channel 51, while the outer end of the docking nozzle 54 is in butt joint and communication with the air flow output end of the fan 6, so as to ensure that the air flow output by the fan 6 can enter the gap channel 51 inside the air hood 5 through the docking nozzle 54.

[0043] Optionally, multiple fans 6 can be provided inside the lamp head housing 1. Correspondingly, multiple docking nozzles 54 can also be integrally formed on the outer wall of the air hood 5. Each docking nozzle 54 is in butt joint and communication with the air flow output end of each fan 6 respectively, so as to input air into the air hood 5 by multiple fans 6 together, which can significantly increase the air flow output of the air hood 5 and further improve the heat dissipation effect on the optical effect component 4.

[0044] Optionally, the blower 6 is a flat blower, and the docking nozzle 54 is integrally formed on the side of the wind cover 5. During installation, the wind cover 5 is linearly docked and communicated with the air flow output port on the side of the blower through the docking nozzle 54 on the side, and this connection structure can help reduce the occupied space inside the stage light.

[0045] Preferably, the wind cover 5 in this embodiment is set as the lamp core housing of the light source 3. That is to say, during production and manufacturing, the housing originally sleeved outside the lamp core in the light source structure is omitted, and the lamp core of the light source 3 is directly embedded into the wind cover 5, making the wind cover 5 directly become the housing of the light source lamp core, so that production and assembly can be more simplified.

[0046] In one embodiment, specifically, a fixed substrate 7 is fixedly installed in the lamp head housing 1. The fixed substrate 7 is connected to the bottom of the wind cover 5. An air cover installation position 71 corresponding to the wind cover 5 is integrally formed on the fixed substrate 7. When installing the stage light, the wind cover 5 is fixedly sleeved in the air cover installation position 71, which can facilitate the installation and positioning of the wind cover 5. At the same time, preferably, two circuit board installation positions 72 symmetrically distributed on the left and right sides of the wind cover installation position 71 are integrally formed on the fixed substrate 7, which can facilitate the installation of the circuit board.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
