Abstract
Description
Technical Field
[0001] The present application relates to the technical field of lamps, and in particular to an LED stage lamp. Background Art
[0002] In the process of continuous development of stage lighting, the functions of stage lighting equipment have been continuously enriched, and a variety of lighting effects can be achieved. Although it meets the needs of various performances, traditional light sources still have disadvantages such as high energy consumption, heat generation, short life and poor safety. In recent years, LED light sources have been widely used in performing arts lighting with the advantages of low energy consumption and low heat generation, while the performance of power, photoelectric conversion efficiency and chromaticity has been improved. LED lights can achieve the combination of light and shadow with art. Under the control of microcomputers, they can make the fastest light effect combination changes according to the needs of the venue and program to achieve the lighting atmosphere effect. Combined with the large-scale program LED display on the existing stage, more exquisite image performances can be presented.
[0003] Common LED stage lights include a housing, LED lamp beads and LED driver power supplies. The LED driver power supplies and LED lamp beads are both installed in the housing. In actual use, the LED lamp beads and the driver power supplies will generate heat. If the heat cannot be discharged in time, it will affect the service life of the LED stage lights. Therefore, the commonly used method is to set a metal heat sink on the housing to increase the contact area between the equipment and the air to increase the heat dissipation speed, but this heat dissipation effect is limited. Therefore, some LED stage lights will be equipped with a cooling fan at the rear of the housing for active heat dissipation. This heat dissipation method requires the opening of heat dissipation holes at the rear of the housing. LED stage lights often need to be used outdoors and often need to adjust the pitch angle. If it rains, the heat dissipation holes at the rear of the housing are easy to float into raindrops, which can easily cause LED stage lighting failures and affect the on-site performance effects. Therefore, it is urgent to propose an LED stage light with better heat dissipation and waterproof effects. Utility Model Content

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.
[0026] like Figure 1-Figure 4 As shown, an LED stage light disclosed in the present application comprises a shell 1, in which an LED light source module 2 and an LED driving power module 3 are installed, the LED light source module 2 and the LED driving power module 3 are arranged at intervals in the shell 1 along its axial direction, and an air-cooling heat dissipation unit 4 is arranged between the LED light source module 2 and the LED driving power module 3; a hollow leg 5 is connected to each side of the shell 1, and both ends of the air-cooling heat dissipation unit 4 are respectively connected to the upper ports of the two hollow legs 5; the lower ends of the two hollow legs 5 are fixedly mounted on a mounting base 6, the interior of the mounting base 6 is a hollow structure, and the lower ports of the two hollow legs 5 are connected to the internal space of the mounting base 6; an air intake unit 7 for side air intake and an exhaust unit 8 for side exhaust are arranged in the mounting base 6, the air intake unit 7 is connected to the lower port of one of the hollow legs 5, and the exhaust unit 8 is connected to the lower port of the other hollow leg 5.
[0027] In the above embodiments, the LED light source module 2 and the LED driving power module 3 are spaced apart in the housing 1 of the present application, so that a space can be formed between the LED light source module 2 and the LED driving power module 3 for the air-cooling heat dissipation unit 4 to be installed. In addition, the heat generated by the LED light source module 2 and the LED driving power module 3 during use can quickly reach the air-cooling heat dissipation unit 4, so that the air-cooling heat dissipation unit 4 can efficiently take away the heat of the LED light source module 2 and the LED driving power module 3. In particular, compared with the traditional LED stage light with a heat sink arranged on the outside of the housing 1, the present application adopts an active heat dissipation method for heat dissipation, and the heat dissipation effect is significantly better, which can effectively improve the service life of the equipment.
[0028] The shell 1 of the present application is installed on the mounting base 6 through the hollow legs 5, and the mounting base 6 is generally fixedly connected to other special structures at the performance site. Therefore, the mounting base 6 is generally in a fixed state when in use. The present application sets both the air intake unit 7 and the exhaust unit 8 in the mounting base 6, which can not only utilize the mounting base 6 to protect the air intake unit 7 and the exhaust unit 8, but also the air intake unit 7 and the exhaust unit 8 can also work stably in the fixed mounting base 6.
[0029] The two hollow legs 5 of the present application can not only support the shell 1, but also serve as a guiding channel for the air flow. The hollow legs 5 connected to the air intake unit 7 can guide the cold air in the environment from the mounting base 6 into the air-cooled heat dissipation unit 4 to exchange heat with the heat dissipated by the LED light source module 2 and the LED driving power supply module 3. The hollow legs 5 connected to the exhaust unit 8 can draw the hot air generated by heat absorption in the air-cooled heat dissipation unit 4 to the mounting base 6 and then discharge it. Since the heat generated by the stage lamp of the present application when in use is guided to the mounting base 6 through the two hollow legs 5 for discharge, and the air inlet connected to the outside is also at the mounting base 6, the shell 1 of the present application does not need to be provided with a heat dissipation fan at the tail like the stage lamp in the prior art, and a heat dissipation hole for ventilation is also provided at its tail. In this way, the integrity of the shell 1 of the present application will be better. In the actual use process, even if it suddenly rains and the pitch angle of the light is adjusted, it is difficult for rainwater to enter the shell 1 to damage the LED light source module 2 and the LED driving power supply module 3, which effectively improves the waterproof performance of the present application, and even if it rains, it will not affect its stable operation.
[0030] Furthermore, if Figure 2 and Figure 3As shown, the air-cooled heat dissipation unit 4 includes two metal heat dissipation plates 41 parallel to each other, the edges of the two metal heat dissipation plates 41 are fixedly connected to the inner wall of the shell 1, a heat dissipation box 42 is fixedly arranged between the two metal heat dissipation plates 41, and the heat dissipation box 42 is provided with a plurality of heat dissipation fins 43 parallel to each other and arranged at equal intervals; a vent 44 is respectively provided on one opposite side of the heat dissipation box 42, and the two vents 44 are respectively connected to the upper ports of the two hollow legs 5.
[0031] In the above embodiments, the metal heat sink 41 of the present application can efficiently conduct the heat dissipated by the LED light source module 2 and the LED driving power module 3 to the heat sink 42 in the shell 1. The two vents 44 of the heat sink 42 are connected to the air intake unit 7 and the exhaust unit 8 through a hollow leg 5 respectively, so there is a continuous airflow inside. The heat sink fins 43 in the heat sink 42 can effectively increase the contact area between the heat conducted by the two metal heat sinks 41 and the flowing air in the heat sink 42, ensuring that the air in the heat sink 42 can fully and efficiently take away the heat, thereby achieving a good heat dissipation effect.
[0032] Furthermore, if Figure 2 and Figure 3 As shown, the upper ends of the two hollow legs 5 are both facing the middle shell 1, and the upper ends of the two hollow legs 5 pass through the side wall of the shell 1 on the adjacent side and are respectively inserted into the two vents 44, and the hollow legs 5 are rotatably connected to the side wall of the shell 1 and the vents 44 on the corresponding side.
[0033] In the above embodiment, the upper end of the hollow leg 5 faces the housing 1, so that the axis of the upper end of the hollow leg 5 is along the horizontal direction, and the upper end of the hollow leg 5 of the present application has an extension section along the horizontal direction, so that the upper end of the hollow leg 5 can be inserted into the corresponding vent 44 after passing through the side wall of the housing 1 on the adjacent side. Since the upper end of the hollow leg 5 is inserted into the vent 44 in the horizontal direction, when it rains, the rain falls from top to bottom, which is different from the axis direction of the upper end of the hollow leg 5 of the present application, so it is difficult for rainwater to flow into the interior of the device from the upper end of the hollow leg 5. In order to further improve the waterproof performance of the device in actual use, a waterproof gasket can be provided at the connection between the hollow leg 5 and the upper end.
[0034] The upper end of the hollow leg 5 of the present application is rotatably connected to the side wall of the shell 1 and the corresponding vent 44, so that it is convenient to adjust the pitch angle of the LED stage light as needed when using it.
[0035] Furthermore, if Figure 4As shown, the exhaust unit 8 includes a heat dissipation fan 81 installed on the mounting base 6, the exhaust end of the heat dissipation fan 81 is fixedly connected to one end of the exhaust pipe 82, and the other end of the exhaust pipe 82 is fixedly connected to the lower port of the hollow support leg 5 on the corresponding side; the outlet end of the heat dissipation fan 81 is fixedly connected to one end of the outlet pipe 83, and the other end of the outlet pipe 83 is fixedly connected to one side wall of the mounting base 6 in the circumferential direction, and a first through hole 84 is opened on the side wall of the mounting base 6 in an area corresponding to the end of the outlet pipe 83 away from the heat dissipation fan 81.
[0036] In the above embodiments, the heat dissipation fan 81 of the present application is preferably an axial flow heat dissipation fan 81, because the axial flow heat dissipation fan 81 is not only low in cost but also can be made relatively small, and is more suitable for use in the limited space of the mounting base 6 of the present application. When the heat dissipation fan 81 is working, a suction force can be generated, and the suction force can draw the hot air in the air-cooling heat dissipation unit 4 along the hollow leg 5 connected to its exhaust pipe 82 into the air outlet pipe 83, and then discharged from the first through hole 84 on the side wall of the mounting base 6 along the air outlet pipe 83, so that it can cooperate with the air-cooling heat dissipation unit 4 in the housing 1 to actively dissipate the heat inside the device, thereby effectively improving the stability and service life of the stage light.
[0037] Furthermore, if Figure 4 As shown, the air intake unit 7 includes an air intake pipe 71 and a second through hole 72, the first through hole 84 and the second through hole 72 are arranged on the same side of the mounting base 6, and there is a gap between the first through hole 84 and the second through hole 72, one end of the air intake pipe 71 is fixedly connected to the lower end of the hollow support leg 5, and the other end of the air intake pipe 71 extends to the second through hole 72 and is fixedly connected to the side wall of the mounting base 6 around it.
[0038] In the above embodiments, under the action of the heat dissipation fan 81 in the exhaust unit 8, the air inlet pipe 71 of the present application is connected to the corresponding hollow leg 5 and can guide the cold air in the environment into the heat dissipation box 42 through the second through hole 72 on the mounting base 6, so as to timely replenish the hot air drawn away by the heat dissipation fan 81, and the newly replenished cold air can continue to efficiently exchange heat with the heat dissipated by the LED light source module 2 and the LED driving power supply module 3, so as to ensure that they operate in a more ideal temperature environment and ensure the use effect.
[0039] Furthermore, if Figure 1 and Figure 3 As shown, a positioning ring 9 is fixedly connected to the upper end of the hollow leg 5 near the side of the shell 1, and a plurality of first positioning holes 10 are evenly arranged on the positioning ring 9 along the circumferential direction, and a second positioning hole 11 is arranged on the shell 1;
[0040] The first positioning hole 10 and the second positioning hole 11 have equal diameters and are both threaded holes, and the distances from the center points of the first positioning hole 10 and the second positioning hole 11 to the axis of the vent 44 are equal; when the second positioning hole 11 is aligned with one of the first positioning holes 10, they can be connected by bolts.
[0041] In the above embodiments, there is a certain damping between the upper port of the hollow leg 5 and the vent 44 of the shell 1 and the heat sink 42 during actual use, so that after adjusting the pitch angle of the LED stage light, it can be stopped at the desired angle, but if the LED stage light is accidentally bumped or touched on the scene, there may still be a risk of the angle being changed. The positioning ring 9 provided on the hollow leg 5 of the present application has a plurality of first positioning holes 10 along the circumferential direction. After the LED stage light has adjusted the pitch angle, one of the first positioning holes 10 on the positioning ring 9 is aligned with the second positioning hole 11 on the shell 1. At this time, the on-site workers use bolts to sequentially screw the first positioning holes 10 and the second positioning holes 11 aligned as above, so that the LED stage light with the adjusted angle can be further limited, thereby effectively preventing it from being accidentally bumped or touched on the performance site and being displaced.
[0042] Furthermore, if Figure 4 and Figure 5 As shown, a grille protection net 12 is installed on the first through hole 84 , and a dust filter net 13 is installed on the second through hole 72 .
[0043] In the above embodiment, the grille protection net 12 on the first through hole 84 can prevent debris from entering the air outlet duct 83, and the dust filter net 13 on the second through hole 72 can filter the air sucked into the device to prevent dust impurities in the air from entering the device.
[0044] Furthermore, if Figure 5 As shown, a rain cover 14 is installed on the upper outer sides of the first through hole 84 and the second through hole 72 .
[0045] In the above embodiments, the rain cover 14 installed above the first through hole 84 and the second through hole 72 can effectively prevent rainwater from drifting into the air outlet duct 83 and the air inlet duct 71 when it rains.
[0046] Furthermore, the metal heat sink 41 , the heat sink box 42 and the heat sink fins 43 are all made of metal aluminum.
[0047] In the above embodiments, metal aluminum is selected to make the metal heat sink 41, the heat sink box 42 and the heat sink fins 43, which not only meets the requirements of good thermal conductivity, but also has light weight and low cost.
[0048] The implementation principle of this embodiment is as follows: when the LED stage light of the present application is in use, the heat generated by the LED light source module 2 and the LED driving power module 3 can be conducted to the heat dissipation fins 43 in the heat dissipation box 42 through the metal heat dissipation plates 41 on their respective sides, and the heat dissipation box 42 will have a continuous flow of air due to the action of the heat dissipation fan 81 in the exhaust unit 8, and the air flow can efficiently exchange heat with the heat on the heat dissipation fins 43, and then the hot air generated after absorbing heat is transported to the exhaust pipe 82 along the hollow legs 5 connected to the exhaust unit 8, and then flows out from the first through hole 84 on the mounting base 6 along the air outlet pipe 83 through the heat dissipation fan 81. Since the air inlet pipe 71 is connected to the external environment through the second through hole 72 on the mounting base 6, the cold air in the external environment can be timely sent to the heat dissipation box 42 along the hollow legs 5 connected thereto while the exhaust unit 8 sucks the air in the heat dissipation box 42, so that a continuous flow of air can be formed in the heat dissipation box 42 to transfer the heat inside it. Compared with the prior art, the present invention has better heat dissipation and waterproof effects.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
