Description

Technical Field

[0001] The present invention relates to the field of stage lights, and more particularly to a light source heat dissipation system and a stage light having the same. Background Art

[0002] With the continuous development of the indoor and outdoor large-scale performance market, the demand for high-power stage lights is getting higher and higher. Most of them use high-power bubble light sources or platinum light sources to meet the brightness and other requirements of stage lights. However, during the operation of stage lights, bubble light sources or platinum light sources are very sensitive to temperature, especially the first and second poles of the wick and the conductive circuit, which need to be controlled in a suitable temperature range. Overheating can easily burn the wick, and too low a temperature will make the wick white, which cannot achieve the ideal lighting effect.

[0003] Existing high-power stage lights have limited heat dissipation capabilities. The heat generated by the light source is easily transferred to the space where the effect components are installed through the sheet metal, causing the effect components or other components of the stage lights to deform or even burn due to excessive temperature. In addition, during the operation of the stage light, the temperature of the entire shell will be very high. After the operation of the stage light, it takes a long cooling time before the staff can directly touch the surface of the lamp body, resulting in a waste of time and cost in maintenance and transportation. Summary of the invention

[0004] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide a light source heat dissipation system and a stage light having the same, so as to solve the problem that the light source itself or other components of the high-power stage light light source heat dissipation system are damaged due to overheating.

[0005] The technical solution adopted by the present invention is: comprising a wick connected to a conductive circuit through a first pole and a second pole, a reflective cup for mounting the wick, a heat insulating sheet for sealing a light outlet of the reflective cup, a first cover body sleeved on one end of the reflective cup close to the light outlet, and a second cover body buckled on the other end of the reflective cup, wherein the first cover body and the second cover body jointly cover the entire reflective cup; one end of the wick is mounted on a mounting seat, the first pole and the second pole are located on the wick and distributed close to both ends thereof; the inner side wall of the reflective cup and the heat insulating sheet form a first cavity, the second cover body and the reflective cup are connected to each other to form a first cavity; The corresponding part of the outer wall of the light cup forms a second cavity, the first cover body and the corresponding part of the outer wall of the reflective cup form a third cavity, the third cavity blocks the heat of the first cavity from propagating along the light emitting direction to outside the light source; the first pole is located in the first cavity, the second pole is located in the second cavity, and also includes a first air outlet arranged on the reflective cup corresponding to the first cavity and a second opening arranged on the second cover body, the first air supply mechanism sends air into the first cavity and discharges it through the first air outlet, and the second air supply mechanism sends air into the second cavity and discharges it through the second opening.

[0006] The light source heat dissipation system is divided into three relatively independent cavities. The first air supply mechanism delivers cold air to the first cavity and promptly delivers the hot air through the first air outlet and then discharges it out of the light source heat dissipation system. The second air supply mechanism delivers air into the second cavity and then dissipates it from the second opening. The first cavity and the second cavity independently discharge the hot air inside each other to avoid mixing and mutual influence of the air flows in the two cavities. In addition, the third cavity acts as a heat insulator, effectively reducing the heat transfer from the first cavity to the space where the effect elements are installed.

[0007] Furthermore, it also includes a fixing plate that is substantially perpendicular to the main optical axis of the reflective cup, the fixing plate has a through hole for the reflective cup to pass through, and the first cover body and the second cover body are respectively buckled on opposite sides of the fixing plate. The fixing plate can simultaneously fix the first cover body and the second cover body, which is convenient for installation.

[0008] Furthermore, the airflow of the first air supply mechanism is directed to the first pole. Since the first pole is very sensitive to temperature, with this arrangement, the cold airflow delivered by the first air supply mechanism can directly take away the heat generated by the first pole during operation, and the temperature of the first pole during operation can be directly affected by adjusting the size of the airflow of the first air supply mechanism, and effectively controlled within an ideal range.

[0009] Furthermore, the airflow of the second air supply mechanism is aimed at the second pole. The cold air flow delivered by the second air supply mechanism can timely take away the heat generated by the second pole during operation. By adjusting the size of the airflow of the second air supply mechanism, the temperature of the second pole during operation can be directly affected and effectively controlled within an ideal range, thereby avoiding damage to the wick due to excessive temperature.

[0010] Furthermore, the extension line of the line connecting the air outlet of the second air supply mechanism and the second pole passes through the second opening, and the airflow sent by the second air supply mechanism flows out from the second opening after passing through the second pole. The cold airflow sent by the second air supply mechanism takes away the heat of the second pole and is directly discharged from the second cavity through the second opening, so that the hot air will not circulate too much in the second cavity, thereby achieving the effect of efficient heat dissipation.

[0011] Furthermore, it also includes an outer box body and a third air supply mechanism that are covered on the outside of the second cover body. The inner side wall of the outer box body and the outer side wall of the second cover body form a fourth cavity. The outer box body is provided with a first opening that is connected to the outside. A part of the first opening is connected to the second opening through an air guide channel. The third air supply mechanism sends air into the fourth cavity and discharges it through the remaining part of the first opening. The second cover body locks as much heat of the reflective cup as possible in the second cavity. At the same time, the setting of the fourth cavity plays a role in heat insulation, preventing the heat in the second cavity from being directly transferred to the outside of the light source heat dissipation system, causing the external temperature of the light source heat dissipation system to be too high. The cold air flow delivered by the third air supply mechanism takes away the heat from the surface of the second cover body, dissipates the heat of the fourth cavity, and can also effectively accelerate the heat dissipation of the second cavity.

[0012] Furthermore, the air guide of the second air supply mechanism passes through the outer box body and is inserted into the second cover body, and the air outlet is located in the second cavity. The second air supply mechanism is used to send cold air outside the light source heat dissipation system into the second cavity, and the heat is discharged outside the light source heat dissipation system through the second opening, so as to effectively control the temperature inside the second cavity.

[0013] Furthermore, it includes a mounting substrate located at the light outlet of the reflective cup, and a fixing plate substantially perpendicular to the main optical axis of the reflective cup, the side plate of the peripheral box body extends to the mounting substrate and is buckled below it, the fixing plate substantially perpendicular to the main optical axis of the reflective cup fixes the reflective cup inside the peripheral box body, the fixing plate has a through hole for the reflective cup to pass through, the reflective cup is located in both the first cover body and the second cover body, the mounting substrate, the fixing plate and the corresponding parts of the peripheral box body form the first cover body, the fixing plate has a through hole for the reflective cup to pass through, the reflective cup is located in both the first cover body and the second cover body. The fixing plate is used to separate the cavity of the peripheral box body, so that the light source heat dissipation system maintains good integrity, improves the airtightness between the components of the light source heat dissipation system, and prevents heat from escaping from the gap due to insufficient tightness, thereby affecting the heat dissipation and heat insulation effects.

[0014] Furthermore, a portion of the first opening is connected to the first air outlet. The hot air in the first cavity flows out through the first air outlet and then is discharged out of the light source heat dissipation system through the first opening, thereby avoiding heat accumulation in the first cavity.

[0015] Furthermore, it also includes an installation box for covering the outer box body and the first cover body, and the side wall of the installation box is provided with at least two ventilation holes, and the ventilation holes are provided with shutters covering themselves. The provision of the shutters does not affect the ventilation effect of the ventilation holes, and also prevents the light emitted by the wick from emitting outside the light source heat dissipation system.

[0016] Furthermore, the first cover has a light hole corresponding to the light outlet of the reflective cup, and the heat insulation sheet is installed on the first cover and seals the light outlet of the reflective cup. Such a configuration does not require the use of other components to fix the heat insulation sheet, simplifies the structure and saves materials, while also ensuring good airtightness of the first cavity and the third cavity.

[0017] Furthermore, the reflective cup includes a main cup and a sub-cup, the sub-cup is buckled on the main cup along the light path, the opening of the sub-cup gradually decreases along the light path, and the maximum opening diameter of the sub-cup is greater than or equal to the maximum opening diameter of the main cup. The provision of the sub-cup improves the color rendering index of the light beam emitted by the light source heat dissipation system and further optimizes the light effect.

[0018] Furthermore, it also includes a fixing plate that is substantially perpendicular to the main optical axis of the reflective cup, the fixing plate has a through hole corresponding to the opening of the main cup, the main cup and the auxiliary cup are respectively fixed to both sides of the fixing plate and both cover the through holes.

[0019] Furthermore, there is a gap between the secondary cup and the main cup to form the first air outlet. A gap is directly left at the connection between the secondary cup and the main cup to serve as the first air outlet, and the hot air in the first cavity is discharged from the first air outlet, without hollowing out the reflective cup to form the first air outlet, which is convenient for processing.

[0020] The present invention also provides a stage light, which has a light source heat dissipation system as described in any of the above items, and also includes a light output lens and a shell that wraps the light source heat dissipation system, the shell is provided with a light output hole, and the lens is arranged at the light output hole.

DETAILED DESCRIPTION

[0030] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0031] like Figure 1 and Figure 2As shown, it includes a wick 300 connected to a conductive circuit through a first pole 310 and a second pole 320, a reflective cup 120 for mounting the wick 300, a heat insulating sheet 112 for sealing a light outlet 121 of the reflective cup 120, a first cover 130 sleeved on one end of the reflective cup 120 near its light outlet 121, and a second cover 150 buckled on the other end of the reflective cup 120, wherein the first cover 130 and the second cover 150 jointly cover the entire reflective cup 120; one end of the wick 300 is mounted on a mounting seat, the first pole 310 and the second pole 320 are located on the wick 300 and distributed near both ends thereof; the inner side wall of the reflective cup 120 and the heat insulating sheet 112 form a first cavity 125, the second cover 150 and the reflective cup 120 are connected to each other by a first cavity 125, and the second cavity 150 and the reflective cup 120 are connected to each other by a first cavity 125. The corresponding part of the outer wall of the cup 120 forms a second cavity 151, the first cover body 130 and the corresponding part of the outer wall of the reflective cup 120 form a third cavity 131, and the third cavity 131 blocks the heat of the first cavity 125 from propagating along the light emitting direction to outside the light source; the first pole 310 is located in the first cavity 125, and the second pole 320 is located in the second cavity 151, and also includes a first air outlet 122 on the reflective cup 120 arranged at the corresponding part of the first cavity 125, and a second opening 152 arranged on the second cover body 150, the first air supply mechanism 210 sends air into the first cavity 125 and discharges it through the first air outlet 122, and the second air supply mechanism 220 sends air into the second cavity 151 and discharges it through the second opening 152.

[0032] The light source heat dissipation system 100 is divided into three relatively independent cavities. The first air supply mechanism 210 delivers cold air to the first cavity 125 and timely delivers the hot air through the first air outlet 122 and then discharges it outside the light source heat dissipation system 100. The second air supply mechanism 220 delivers air into the second cavity 151 and then dissipates it from the second opening 152. The first cavity 125 and the second cavity 151 independently discharge the hot air inside each other to avoid mixing and affecting the airflow in the two cavities. In addition, the third cavity 131 plays a heat insulation role, effectively reducing the heat transfer from the first cavity 125 to the space equipped with the effect element.

[0033] Preferably, the first air supply mechanism 210 includes two first fans 211 and two first air nozzles 212 respectively connected to the first fans 211, and the two first air nozzles 212 are arranged opposite to each other, so that the cold air drawn in by the first fans 211 blows through the first cavity 125 as much as possible and then is discharged from the first air outlet 122. Similarly, the second air supply mechanism 220 includes two second fans 221 and two second air nozzles 222 respectively connected to the second fans 221.

[0034] In a preferred embodiment of the present invention, a fixing plate 140 is also included which is substantially perpendicular to the main optical axis of the reflective cup 120. The fixing plate 140 has a through hole 141 for the reflective cup 120 to pass through. The first cover 130 and the second cover 150 are respectively buckled on opposite sides of the fixing plate 140. The fixing plate 140 is used to fix the first cover 130 and the second cover 150 at the same time, which is convenient for installation.

[0035] Preferably, the angle between the optical paths of the fixing plate 140 and the reflective cup 120 is in a range of 60° to 90°. Here, the optical paths of the fixing plate 140 and the reflective cup 120 can also be regarded as being perpendicular.

[0036] Optionally, the number of the reflective cup 120 is one, and its opening gradually increases along the light path direction. The reflective cup 120 passes through the fixing plate 140 and is tightly combined with it, so that the third cavity 131 is sealed, further enhancing its heat insulation effect.

[0037] like Figures 2 to 4 As shown, in a preferred embodiment of the present invention, the airflow of the first air supply mechanism 210 is aligned with the first pole 310. Since the first pole 310 is very sensitive to temperature, with such a configuration, the cold airflow delivered by the first air supply mechanism 210 can directly take away the heat generated by the first pole 310 during operation, and the temperature of the first pole 310 during operation can be directly affected by adjusting the size of the airflow of the first air supply mechanism 210, and effectively controlled within an ideal range.

[0038] In a preferred embodiment of the present invention, the airflow of the second air supply mechanism 220 is aimed at the second pole 320. The cold air flow delivered by the second air supply mechanism 220 can promptly take away the heat generated by the second pole 320 during operation. By adjusting the size of the airflow of the second air supply mechanism 220, the temperature of the second pole 320 during operation can be directly affected and effectively controlled within an ideal range, thereby avoiding damage to the wick 300 due to excessive temperature.

[0039] In a preferred embodiment of the present invention, the extension line of the line connecting the air outlet of the second air supply mechanism 220 and the second pole 320 passes through the second opening 152, and the airflow sent by the second air supply mechanism 220 flows out from the second opening 152 after passing through the second pole 320. The cold airflow sent by the second air supply mechanism 220 takes away the heat of the second pole 320 and is directly discharged from the second cavity 151 through the second opening 152, and the hot air will not flow too much in the second cavity, which plays a role in efficient heat dissipation. In this embodiment, only one of the second air supply mechanisms 220 is configured in this way.

[0040] like Figures 2 to 4 As shown, in a preferred embodiment of the present invention, it also includes an outer box body 160 and a third air supply mechanism 230 that are covered on the outside of the second cover body 150. The inner wall of the outer box body 160 and the outer wall of the second cover body 150 form a fourth cavity 161. The outer box body 160 is provided with a first opening 162 connected to the outside, and a part of the first opening 162 is connected to the second opening 152 through an air guide channel. The third air supply mechanism 230 sends air into the fourth cavity 161 and discharges the remaining part through the first opening 162. The second cover body 150 locks as much heat of the reflective cup 120 as possible in the second cavity 151. At the same time, the setting of the fourth cavity 161 plays a role of heat insulation, preventing the heat in the second cavity 151 from being directly transferred to the outside of the light source heat dissipation system 100 and causing the external temperature of the light source heat dissipation system 100 to be too high. The cold air flow delivered by the third air supply mechanism 230 takes away the heat from the surface of the second cover body 150, dissipates the heat of the fourth cavity 161, and can also effectively accelerate the heat dissipation of the second cavity 151.

[0041] Preferably, the third air supply mechanism 230 includes two third fans 231 and two third air nozzles 232 connected to the third fans 231, and the third air nozzles 232 are arranged opposite to each other.

[0042] Preferably, the first fan 211, the second fan 221 and the third fan 231 are all fixed to the outer side wall of the outer box body 160 to prevent the fan from being affected in operation or even damaged due to excessive temperature.

[0043] like Figure 7 As shown, preferably, the second opening 152 is connected to the first opening 162 through a plurality of sheet metal parts.

[0044] In a preferred embodiment of the present invention, the air guide of the second air supply mechanism 220 passes through the outer box body 160 and is inserted into the second cover body 150, and the air outlet is located in the second cavity 151. The second air supply mechanism 220 is used to send cold air outside the light source heat dissipation system 100 into the second cavity 151, and the heat is discharged outside the light source heat dissipation system 100 through the second opening 152, so as to effectively control the temperature inside the second cavity 151.

[0045] In a preferred embodiment of the present invention, a mounting substrate 110 is included which is located at the light outlet 121 of the reflective cup 120. The side panels of the peripheral box body 160 extend to the mounting substrate 110 and are buckled thereunder. A fixing plate 140 which is substantially perpendicular to the main optical axis of the reflective cup 120 fixes the reflective cup 120 inside the peripheral box body 160. The fixing plate 140 has a through hole 141 for the reflective cup 120 to pass through. The reflective cup 120 is located in both the first cover body 130 and the second cover body 150. The mounting substrate 110, the fixing plate 140 and the corresponding parts of the peripheral box body 160 form the first cover body 130. The peripheral box body 160 and the mounting substrate 110 form a complete cavity, and the fixing plate 140 is used to separate the formed cavity from the peripheral box body 160, so that the fixing plate 140, the mounting substrate 110 and the corresponding parts of the peripheral box body 160 form the first cover body 130, that is, the side of the first cover body 130 and the side of the peripheral box body 160 are integrated, saving materials and simplifying the structure, making installation more convenient. The first cover body 130 and the peripheral box body 160 are more tightly combined, separating the cavity, so that the structure of the entire light source heat dissipation system 100 maintains good integrity, improves the sealing of the structure between the components of the light source heat dissipation system 100, and prevents heat from escaping from the gap due to insufficient tightness, affecting the heat dissipation and heat insulation effects.

[0046] Preferably, there is one first opening 162 , and the second opening 152 is connected to a portion of the first opening 162 through a sheet metal component.

[0047] Optionally, there are multiple first openings 162 , and the second opening 152 is connected to one of the multiple first openings 162 through a sheet metal part.

[0048] In a preferred embodiment of the present invention, a portion of the first opening 162 is connected to the first air outlet 122. The hot air in the first cavity 125 flows out through the first air outlet 122 and then is discharged out of the light source heat dissipation system 100 through the first opening 162, thereby avoiding heat accumulation in the first cavity 125.

[0049] Preferably, the first air outlet 122 is connected to the first opening 162 through a plurality of sheet metals. After the first air supply mechanism 210 delivers cold air into the first cavity 125 , most of the hot air is discharged from the first air outlet 122 along the air duct formed by the sheet metal through the first opening 162 to the outside of the light source cooling system 100 , thereby completing the heat dissipation of the first cavity 125 .

[0050] like Figure 1 and Figure 4As shown, in a preferred embodiment of the present invention, it also includes an installation box 400 that covers the peripheral box body 160 and the first cover body 130, and at least two vents 410 are provided on the side wall of the installation box 400, and the vents 410 are all provided with shutters covering themselves. At least one of the vents 410 takes in air, and the other vents 410 discharge air. The vents 411 do not affect the ventilation effect of the vents 410 by providing the shutters, and also prevent the light emitted by the wick 300 from emitting outside the light source heat dissipation system 100.

[0051] Preferably, the number of the ventilation openings 410 is two and they are arranged opposite to each other.

[0052] In a preferred embodiment of the present invention, the first cover 130 has a light hole corresponding to the light outlet 121 of the reflective cup 120, and the heat insulating sheet 112 is installed on the first cover 130 and seals the light outlet 121 of the reflective cup 120. Such a configuration does not require the use of other components to fix the heat insulating sheet 112, simplifies the structure and saves materials, and also ensures good airtightness of the first cavity 125 and the third cavity 131.

[0053] like Figure 1 to Figure 2 As shown, in a preferred embodiment of the present invention, the reflective cup 120 includes a main cup 123 and a sub-cup 124. The sub-cup 124 is buckled on the top of the main cup 123 along the light path. The opening of the sub-cup 124 gradually decreases along the light path, and the maximum opening diameter of the sub-cup 124 is greater than or equal to the maximum opening diameter of the main cup 123. The provision of the sub-cup 124 improves the color rendering index of the light beam emitted by the light source heat dissipation system 100 and further optimizes the light effect.

[0054] like Figure 6 As shown, preferably, the first pole 310 is located in the sub-cup 124, the first air supply mechanism 210 passes through the sub-cup 124 and is inserted into the first cavity 125 to deliver cold air, and the first air outlet 122 is arranged in the sub-cup 124. The cold air drawn in by the first air supply mechanism 210 takes away the heat of the first pole 310 and flows to the first air outlet 122 and is discharged from the light source heat dissipation system 100 through the first opening 162, thereby preventing excessive hot air from being retained in the first cavity 125 and flowing to the bottom of the wick 300, which eventually causes the wick 300 to be damaged or directly burned due to excessive temperature.

[0055] like Figure 2As shown, in a preferred embodiment of the present invention, it also includes a fixing plate 140 that is substantially perpendicular to the main optical axis of the reflective cup 120, and the fixing plate 140 has a through hole 141 corresponding to the opening of the main cup 123, and the main cup 123 and the sub-cup 124 are respectively fixed on both sides of the fixing plate 140 and both are covered with the through hole 141.

[0056] like Figure 1 and Figure 5 As shown, the first longitudinal cross-sectional view and the second longitudinal cross-sectional view are perpendicular to each other. In a preferred embodiment of the present invention, a gap is provided between the secondary cup 124 and the main cup 123 to form the first air outlet 122. A gap is directly provided at the connection between the secondary cup 124 and the main cup 123 to serve as the first air outlet 122, and the hot air in the first cavity 125 is discharged from the first air outlet 122, without hollowing out the reflective cup 120 to form the first air outlet 122, which is convenient for processing.

[0057] The present invention also provides a stage light, which has a light source heat dissipation system 100 as described in any of the above items, and also includes a light output lens and a shell that wraps the light source heat dissipation system 100, the shell is provided with a light output hole, and the lens is arranged at the light output hole.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention.
