[0026] The following combination Figures 1 to 9 Embodiments of the present invention are described in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The features defined as "first" and "second" are used to distinguish the feature names, and do not have special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] As the demand for lighting brightness in stage settings increases, the power of LED light-emitting diodes (LEDs) in stage lighting fixtures is increasing, while the volume requirements for stage lighting fixtures are tending towards miniaturization. LED light-emitting diodes release a large amount of heat during operation. If this heat is not transferred in a timely manner, the internal temperature of the LED light-emitting diodes will rise sharply, affecting the service life and performance of the LED light-emitting diodes. In current products, although the lamps are equipped with structures for dissipating heat from the LED light-emitting diodes, the internal air intake and exhaust channels of the lamps are long, and the heat exchange efficiency is limited. In addition, the internal air paths of existing lamps are connected in series, and the energy released by the operation of each component interferes with each other, which can easily cause key components in the optical system or electronic control system to burn out.

[0030] The present invention relates to a stage lighting fixture, comprising a heat dissipation structure 10, an LED illuminator 20, a second isolation assembly 30, and an emission structure 40. The LED illuminator 20 is mounted on the heat dissipation structure 10. The second isolation assembly 30 comprises a CMY support plate, a lamp body cover 32, and a lamp body side cover 33. The CMY support plate is provided with a light hole coaxial with the LED illuminator 20. The lamp body side cover 33 is connected to the heat dissipation structure 10. The lamp body cover 32 and the lamp body side cover 33 are sealed along the circumference of the CMY support plate. The emission structure 40 is used to shape the emitted light of the LED illuminator 20. The emission structure 40 is connected to the lamp body cover 32. Considering that different components included in the optical system and the electronic control system have different tolerances to temperature, the stage lighting fixture separates the heat dissipation structure 10, in which the LED illuminator 20 is mounted, and the emission structure 40 into independent chambers through the second isolation assembly 30. This reduces the impact of heat released by the LED illuminator 20 during use on other subsystem components and prevents high-temperature burnout of precision key components.

[0031] Furthermore, the second isolation component 30 also includes a cover support structure 34, which is configured as a connecting ear installed on the upper surface of the CMY support plate. The lamp body cover 32 is connected to the connecting ear by fastening bolts to achieve relative fixation of the lamp body cover 32 and the CMY support plate.

[0032] In some embodiments, in order to enhance the isolation effect between the heat dissipation structure 10 and the emission structure 40, the lamp body surface cover 32 is provided with a first isolation groove, and the lamp body side cover 33 is provided with a second isolation groove. Isolation cotton 35 is pasted in the first isolation groove and the second isolation groove. The isolation cotton 35 is interference fit with the outer contour of the CMY support plate to form a 360° closed isolation layer to separate the air path of the heat dissipation structure from the air path of the emission structure.

[0033] Other structures and operations of the stage lighting fixture are well known in the relevant art to those skilled in the art and will not be described in detail here. The heat dissipation structure 10 will be introduced in detail below.

[0034] The present invention relates to a heat dissipation structure 10 for an LED light-emitting body 20. The heat dissipation structure 10 includes a first mounting frame 110, a radiator 120, a plurality of heat dissipation fans 131, a second mounting frame 140, an air inlet fan 132, and two air outlet fans 133. The first mounting frame 110 is provided with a first hole for mounting the LED light-emitting body 20 and a plurality of second holes for heat dissipation and ventilation. The plurality of second holes are arranged along the circumference of the first hole; the radiator 120 includes a fixed base plate 121 and a heat pipe assembly. The heat pipe assembly is passed through the fixed base plate 121. One end of the fixed base plate 121 is mounted on the first mounting frame 110, and the other end is provided with a first fin group 1211. The first fin group 1211 is provided with a second fin group 123 on both sides. The second fin group 123 is provided on both sides. The fin group 123 is mounted on the first mounting frame 110; the cooling fan 131 is mounted on the first mounting frame 110 corresponding to the second hole position, and the cooling fan 131 communicates with the second fin group 123 through the second hole position to achieve heat exchange; the second mounting frame 140 is fixedly connected to the first mounting frame 110, and the second mounting frame 140 is provided with a third hole position for the entry of cooling gas and a fourth hole position for the exit of high-temperature gas; the air inlet fan 132 is mounted on the second mounting frame 140 corresponding to the third hole position, and the air inlet fan 132 communicates with the first fin group 1211 through the third hole position to allow the entry of cooling gas; the air outlet fan 133 is mounted on the second mounting frame 140 corresponding to the fourth hole position, and the two air outlet fans 133 are mounted oppositely on both sides of the first fin group 1211. The heat dissipation structure 10 connects the LED light-emitting body 20 and the heat sink 120 through the first mounting frame 110. The heat sink 120 directly passes the heat pipe assembly through the fixed base plate 121 without bending or flattening, thereby ensuring the structural integrity and heat dissipation performance of the heat pipe assembly.

[0035] With reference to the accompanying drawings, the first mounting frame 110 includes fixing pillars 113, a radiator fixing plate 111, and spacer columns 118. The radiator 120 is mounted below the radiator fixing plate 111 via the fixing pillars 113, thereby securing the radiator 120 relative to the first mounting frame 110. The cooling fan 131 is mounted on the radiator fixing plate 111 via the spacer columns 118, thereby securing the cooling fan 131 relative to the first mounting frame 110.

[0036] Specifically, the heat dissipation structure 10 further includes a side cover support structure 1122, which is fixed to the left and right sides of the first mounting frame 110 via fastening bolts. The side cover support structure 1122 is fixedly connected to the lamp body side cover 33 to securely connect the heat dissipation structure 10 to the second isolation assembly 30. It will be appreciated that the side cover support structure 1122 is provided with a U-shaped slot for accommodating the second isolation slot.

[0037] It is understood that a portion of the cooling gas in the external air enters through the air inlet fan 132, undergoes sufficient heat exchange with the evaporation portion of the heat sink 120 via the surface of the first fin group 1211, and is then discharged by the air outlet fan 133. The other portion directly passes through the surface of the second fin group 123, undergoes sufficient heat exchange with the condensation portion of the heat sink 120, and then flows through the second hole to the heat dissipation fan 131 for discharge. The heat dissipation structure 10 separates the heat exchange between the evaporation portion and the condensation portion of the heat sink 120, preventing mutual interference between the two gas heat exchange processes, shortening the heat exchange path between the refrigerant and the various heat-generating components, thereby improving heat transfer efficiency and ensuring the normal operation of the LED light-emitting body 20.

[0038] In this embodiment, the cooling fan 131, the air inlet fan 132, and the air outlet fan 133 are all configured as axial flow fans. Axial flow fans have a high flow rate and can quickly discharge high-temperature gases that have completed heat exchange within the heat dissipation structure 10. It is understood that the air inlet fan 132 and the air outlet fan 133 can also be replaced with a blower and an exhaust fan to achieve rapid heat exchange within the first fin group 1211. In some embodiments, to enhance heat exchange, the blades and casing of the axial flow fan are made of metal.

[0039] Furthermore, the heat dissipation structure 10 includes a rear end cover 160, which is fixedly connected to the first mounting frame 110. Specifically, the first mounting frame 110 includes a rear cover support structure 1121, and the rear end cover 160 is fixedly connected to the radiator fixing plate 111 via the rear cover support structure 1121. The rear end cover 160 has a first air inlet 161 corresponding to the air inlet fan 132 and an air outlet 163 arranged around the peripheral wall of the rear end cover 160. In this embodiment, the rear end cover 160 is configured as a semi-enclosed cover structure. Cooling gas enters the heat dissipation structure 10 through the first air inlet 161 of the rear end cover 160, flows through the first fin group 1211, and exchanges heat with its surface. The outlet fan 133 blows the high-temperature gas that has completed the heat exchange to the air outlet 163 and out of the heat dissipation structure 10, completing the heat exchange of the evaporation portion of the radiator 120. In conjunction with the accompanying drawings, the air outlet 163 is arranged 360° around the peripheral wall of the cover structure, which facilitates the immediate outflow of high-temperature gas in the heat dissipation structure 10, shortens the outflow path of high-temperature gas, and at the same time expands the cross-sectional area of ​​the gas flow path in a limited space, thereby improving heat exchange efficiency.

[0040] As shown in the accompanying drawings, rear cover 160 also has a second air inlet 162, which communicates with second fin assembly 123 to introduce cooling air. As shown in the accompanying drawings, second air inlet 162 is positioned corresponding to second fin assembly 123 to shorten the cooling air's entry path. The cooling air then exchanges heat with the surfaces of second fin assembly 123. The high-temperature air, which has undergone heat exchange, is then guided by cooling fan 131 and discharged from heat dissipation structure 10 through surrounding air outlet 163, completing heat exchange for the condensing portion of radiator 120.

[0041] Furthermore, the air outlet 163 is provided with a plurality of blades 1631 forming a louver structure. The blades 1631 have inclined guide portions 1632. The guide portions 1632 are used to slow the backflow of high-temperature gas at the air outlet 163. Specifically, the guide portions 1632 form an angle of 30° to 45° with the horizontal plane, extending the high-temperature gas return path, preventing the high-temperature airflow from the air outlet 163 from quickly flowing back to the heat dissipation structure 10, and ensuring the normal operation of the LED light-emitting body 20.

[0042] Furthermore, the heat dissipation structure 10 includes a first isolation assembly 150, which includes an isolation bracket 151. The isolation bracket 151 is fixedly connected to the first mounting frame 110. The isolation bracket 151 is provided corresponding to the fourth hole position and is arranged between the inner wall of the rear end cover 160 and the second mounting frame 140. Specifically, the isolation bracket 151 is fixedly connected to the radiator fixing plate 111 using fastening bolts. The inner edge of the isolation bracket 151 contacts the outer edge of the second mounting frame 140 to separate the heat dissipation structure 10 into an air inlet cavity and an air outlet cavity that are not connected to each other, thereby preventing the cooling gas in the air inlet cavity from mixing with the high-temperature gas in the air outlet cavity, thereby affecting the heat dissipation efficiency of the LED light-emitting body 20.

[0043] In some embodiments, in order to further separate the air inlet cavity and the air outlet cavity, the first isolation assembly 150 also includes an isolation plate 152, which is fixed to the inner wall of the rear end cover 160 with fastening bolts. The isolation plate 152 and the isolation bracket 151 are circumferentially joined along the inner wall of the rear end cover 160 to form an annular isolation layer. The annular isolation layer cooperates with the first mounting frame 110 and the inner wall of the rear end cover 160 to complete the separation of the air inlet cavity and the air outlet cavity, thereby avoiding interference between cold and hot air flows and improving heat transfer efficiency.

[0044] Furthermore, the heat dissipation structure 10 includes a silencer 114, which is installed between the cooling fan 131 and the radiator fixing plate 111. A through hole is provided in the silencer 114 corresponding to the second hole position to form a silencer cavity. The silencer cavity is provided with a turbulent structure along the circumferential wall to change the frequency of the gas within the cavity. Specifically, in this embodiment, the turbulent structure is configured as a stepped annular structure to change the frequency of the gas flow within the silencer cavity, preventing resonance caused by the gas frequency aligning with the rotational frequency of the cooling fan 131, thereby reducing the operating noise of the cooling fan 131 and thereby reducing the operating noise of the heat dissipation structure 10.

[0045] In some embodiments, a first shock-absorbing pad 116 is further disposed between the silencer 114 and the cooling fan 131. It will be appreciated that the first shock-absorbing pad 116 is used to reduce vibration transmission during operation of the cooling fan 131, thereby reducing noise generated during operation of the cooling fan 131. In some embodiments, to ensure the shock-absorbing effect of the first shock-absorbing pad 116, the first shock-absorbing pad 116 is made of a soft material, such as sponge, rubber, or silicone.

[0046] In this embodiment, a second shock-absorbing pad 141 is provided between the air intake fan 132 and the second mounting bracket 140 to reduce the operating noise of the air intake fan 132. Furthermore, a noise reduction net 142 is provided on the air intake side of the air intake fan 132. The ribs of the noise reduction net 142 are smooth, tubular in shape to reduce frictional cutting of the air, thereby reducing the operating noise of the air intake fan 132. In some embodiments, the heat dissipation structure 10 includes a shock-absorbing column 143, which is sequentially arranged to pass through the noise reduction net 142, the air intake fan 132, and the second mounting bracket 140 to achieve relative fixation between the noise reduction net 142 and the air intake fan 132, thereby reducing the transmission of vibration during the operation of the air intake fan 132.

[0047] Furthermore, the heat pipe assembly includes a plurality of first heat pipes 1221 and a plurality of second heat pipes 1222. In this embodiment, the first heat pipes 1221 and the second heat pipes 1222 are arranged in two layers, and the first heat pipes 1221 and the second heat pipes 1222 are arranged at intervals. Referring to the accompanying drawings, each first heat pipe 1221 is arranged laterally at intervals from each second heat pipe 1222, and the extended ends of the first heat pipes 1221 and the extended ends of the second heat pipes 1222 respectively penetrate the two second fin groups 123 to improve heat exchange efficiency.

[0048] In existing products, heat pipes in heat exchangers are arranged in a bent or flattened configuration. However, this bent structure increases the heat transfer distance of the heat pipe unit and also forms wrinkles inside and outside the heat pipe, damaging the capillary structure within the heat pipe, thereby affecting the transmission of liquid within the heat pipe, reducing heat transfer efficiency, and increasing manufacturing costs. In this embodiment, the first heat pipe 1221 and the second heat pipe 1222 are both configured as straight pipes. The first heat pipe 1221 and the second heat pipe 1222 are directly inserted through the fixed base plate 121 to prevent damage to the heat pipe's capillary structure and affect heat exchange. The straight pipe design is also compact and suitable for small stage lighting fixtures.

[0049] In conjunction with the accompanying drawings, the first mounting frame 110 includes an LED illuminator fixing plate 115 and a positioning pin 119. The LED illuminator fixing plate 115 is provided with a first positioning hole that cooperates with the positioning pin 119, and the fixed base plate 121 is provided with a second positioning hole that cooperates with the positioning pin 119. The LED illuminator fixing plate 115 and the fixed base plate 121 are pin-connected to position the LED illuminator 20. It can be understood that the first positioning hole and the second positioning hole cooperate with the positioning pin 119 to achieve positioning adjustment of the LED illuminator fixing plate 115 and the fixed base plate 121 to ensure that the optical axis can be actively corrected when the LED illuminator 20 is installed, ensuring that the LED illuminator 20 is coaxial with the lens group to avoid product light deviation. It can be understood that the first mounting frame 110 also includes a support column 1151, which is used to achieve a fixed connection between the LED illuminator fixing plate 115 and the LED illuminator 20.

[0050] Furthermore, the heat dissipation structure 10 includes a transition piece 117, which has an inner hole that mates with the LED luminaire 20. This transition piece 117 is used to secure the LED luminaire 20 relative to the CMY support plate. Specifically, the inner hole of the transition piece 117 forms an interference fit with the outer contour of the LED luminaire 20, while the peaks and valleys of the transition piece 117 and the CMY support plate form an interference fit. In some embodiments, to prevent airflow interference between the heat dissipation structure 10 and the emission structure 40, the inner hole of the transition piece 117 is fabricated using a rubber coating process.

[0051] The present invention also relates to a thermal management system for an LED light-emitting body 20, which is applied to the aforementioned heat dissipation structure 10. The thermal management system includes a temperature sensor and a control system. The temperature sensor is used to collect the real-time temperature of the LED light-emitting body 20; the control system is electrically connected to the temperature sensor, and the control system is electrically connected to the cooling fan 131, the air intake fan 132, and the air outlet fan 133 respectively. The control system independently controls the operation of the cooling fan 131, the air intake fan 132, and the air outlet fan 133 according to the real-time temperature collected by the temperature sensor.

[0052] Furthermore, the temperature sensor collects the real-time temperature inside the heat dissipation structure 10. The control system includes an LED control board and a fan control board. According to the changes in the internal temperature of the heat dissipation structure 10 and the temperature of the LED light-emitting body 20 monitored by the temperature sensor, the speed of the heat dissipation fan 131, the air inlet fan 132, and the air outlet fan 133 are adjusted respectively to ensure that the temperature inside the heat dissipation structure 10 is always within the rated operating temperature range of the LED light-emitting body 20, thereby ensuring the normal use of the stage lighting fixture.

[0053] The heat dissipation structure 10 involved in the present invention makes full use of space, has a compact structure, and reduces the overall size of the product. The second isolation component 30 separates the heat dissipation structure 10 into an air inlet cavity and an air outlet cavity, distinguishing the entry of cooling gas from the discharge of high-temperature gas. The rear end cover 160 is provided with an annular air outlet 163 to shorten the heat exchange path and improve the heat exchange efficiency. The thermal management system independently controls the heat dissipation fan 131, the air inlet fan 132, and the air outlet fan 133 according to the real-time temperature changes in the heat dissipation structure 10, thereby facilitating the temperature control and monitoring management inside the heat dissipation structure 10.
