Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to an omnidirectional convection stage lamp. Background Art

[0002] Indoor stage lights can be used in a variety of scenarios, such as theaters, concert halls, bars or other indoor performance venues, which require a slightly lower waterproof level than outdoor performance lamps. Most indoor stage lights on the market use fans and radiators to effectively dissipate heat from the electronic components inside the lamp body. As the power of the light source increases and the functions of the lamps become more diverse, the heat generated by the stage lights during operation is also increasing, which will undoubtedly increase the number of fans and the size of the radiator.

[0003] However, since indoor stage lights are used indoors, users may have higher requirements for the noise of the lamps, and too many fans will increase the noise of the lamps when they are working, which will directly affect the performance effect or the atmosphere of the environment. At this time, a stage light with low noise and good heat dissipation effect is more popular in the market. Utility Model Content

[0004] The utility model is to overcome at least one defect of the prior art and provide an omnidirectional convection stage lamp, which effectively improves the heat dissipation efficiency inside the lamp head.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an omnidirectional convection stage light, comprising a lamp head with a light outlet, a supporting frame plate located inside the lamp head and arranged relatively, a light outlet lens covering the light outlet, and a lens cover arranged above the light outlet lens, the lens cover is provided with a light through hole corresponding to the light outlet lens, and comprises an inner ring and an outer ring, the inner ring is arranged closer to the light outlet lens than the outer ring, a plurality of spirally distributed air guide plates are arranged between the outer ring and the inner ring, an air duct is formed between two adjacent air guide plates, a first port of the air duct is located above the light outlet lens, and a second port is connected to the inside of the lamp head.

[0006] When the stage light is hung on a truss for use, the air inside the lamp body is heated and expanded by the working electronic components. The cooler air outside the lamp head enters the lamp body from the air duct due to the pressure difference, and the several spirally distributed air guides guide the cold air passing through them in an orderly manner, so that the cold air entering the lamp head can evenly contact and cool the working electronic components. Similarly, when the stage light is placed upright on the ground for use, the hotter air in the lamp head flows out from the air duct. During the flow process, the several air guides will also guide the flow of air in an orderly manner, achieving a omnidirectional convection heat dissipation effect. At the same time, the several air guides can not only act as reinforcing ribs, but also increase the heat dissipation area of ​​the lens cover.

[0007] Furthermore, it also includes a shading plate located in the lens cover and used to block stray light from entering the second port, so as to avoid stray light from being emitted from the air duct and forming glare on the target plane.

[0008] Furthermore, the outer ring is extended with at least two first connection columns for connecting with the sunshade, so that the sunshade is tightly connected with the outer ring to ensure light shielding.

[0009] Furthermore, a second connecting column for connecting to the support frame plate extends from the lower side of the inner ring, and the lens cover is stably mounted on the support frame plate through the second connecting column to prevent the lens cover from accidentally falling off during the rotation of the lamp head.

[0010] Furthermore, the lamp holder also includes at least two side covers that are covered on the support frame plate, and the side covers and the lens cover are interlocked to form a lamp cavity, and at least one of the side covers is provided with a vent. By providing the vent, the heat inside the lamp holder can be effectively dissipated in cooperation with the air duct according to actual conditions; when the external cold air enters the interior of the lamp holder from the air duct, it exchanges heat with the electronic components inside the lamp holder to become a gas with a higher temperature, and finally flows out from the vent. Similarly, when the external cold air enters the interior of the lamp holder from the vent, the gas with a higher temperature is discharged from the air duct to the outside of the lamp holder, thereby fully realizing the effect of all-round convection.

[0011] Furthermore, the inner ring and the outer ring are connected to the two sides of the air guide plate, respectively. The inner ring, the outer ring and the air guide plate form a complete air duct to avoid air leakage and guide the air flow passing through them in an orderly manner.

[0012] Furthermore, a fan is provided inside the lamp holder and used to agitate the air flow inside the lamp holder. By adding the fan, the air flow inside the lamp holder can be further guided, so that the cold air can fully exchange heat with the components inside the lamp holder, further improving the heat dissipation efficiency.

[0013] Furthermore, the inner diameter of the inner ring is smaller than the inner diameter of the outer ring, and the air guide plate connects the inner side of the inner ring with the inner side of the outer ring, so that one side of the first port is inclined toward the outer ring. Compared with the solution of making the first port completely perpendicular to the light output lens, such a setting can allow more gas to pass through the air duct, thereby accelerating the ventilation efficiency of the air duct.

[0014] Furthermore, the air duct allows the airflow entering and exiting the air duct to flow around the periphery of the light output lens, thereby effectively dissipating heat for the light output lens and preventing the light output lens from fogging.

[0015] Furthermore, it also includes a support arm for pivotally connecting the lamp head and a bottom chassis for pivotally connecting the support arm, so that the lamp head can rotate around at least two angles relative to the bottom chassis. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] When the stage light is hung on a truss for use, the air in the lamp body is heated and expanded by the working electronic components and shows an upward trend. The colder air outside the lamp head 100 enters the interior of the lamp body from the air duct 250 due to the pressure difference, and the plurality of spirally distributed air guide plates 240 guide the cold air passing through them in an orderly manner, so that the cold air entering the interior of the lamp head 100 can evenly contact and cool the working electronic components; similarly, when the stage light is placed upright on the ground for use, the hotter air in the lamp head 100 flows out from the air duct 250. During the flow process, the plurality of air guide plates 240 also guide the flowing air flow in an orderly manner, achieving a omnidirectional convection heat dissipation effect. At the same time, the plurality of air guide plates 240 not only serve as reinforcing ribs, but also increase the heat dissipation area of ​​the lens cover 200.

[0025] Preferably, the light output lens 120 is fixedly mounted on the support frame plate 110 via a substrate 121 .

[0026] Preferably, the air guide plate 240 is arc-shaped.

[0027] Preferably, the inner ring 220, the outer ring 230 and the plurality of wind guide plates 240 are integrally formed, and the material used is preferably plastic, which has the advantages of being light and easy to process.

[0028] Preferably, the lamp head 100 also includes a radiator 130 arranged at one end away from the light output lens 120. The hot air in the lamp head 100 exchanges heat with the radiator 130, so that the lamp head 100 is further cooled. Several air ducts 250 arranged on the lens cover 200 cooperate with the radiator 130, so that the stage light can achieve all-round convection without the action of a fan, thereby meeting the heat dissipation requirements of the stage light when it is working.

[0029] Preferably, the air guide plates 240 are evenly distributed along the circumference of the inner ring 220, and each of the air guide plates 240 has the same thickness.

[0030] Optionally, dustproof cotton may be provided at the second port 252 to prevent external dust from entering into the interior of the lamp holder 100 .

[0031] In a preferred embodiment of the utility model, a light shielding plate 260 is further included, which is located in the lens cover 200 and is used to shield stray light from entering the second port 252, so as to prevent stray light from being emitted from the air duct 250 and forming glare on the target plane.

[0032] In a preferred embodiment of the present invention, the outer ring 230 is extended with at least two first connecting posts 231 for connecting with the shading plate 260. The shading plate 260 is tightly connected with the outer ring 230 to ensure light shielding.

The side covers 300 and the lens cover 200 are interlocked to form a lamp cavity, and at least one of the side covers 300 is provided with a vent 310. By providing the vent 310, the heat inside the lamp holder 100 can be effectively dissipated in cooperation with the air duct 250 according to actual conditions; when the external cold air enters the interior of the lamp holder 100 from the air duct 250, it undergoes heat exchange with the electronic components inside the lamp holder 100 to become a gas with a higher temperature, and finally flows out from the vent 310. Similarly, when the external cold air enters the interior of the lamp holder 100 from the vent 310, the gas with a higher temperature is discharged from the air duct 250 to the outside of the lamp holder 100, thereby fully realizing the effect of omnidirectional convection.

[0038] Preferably, there are two side covers 300, both of which are screwed to the support frame plate 110. The lens cover 200 is provided with a first overlap edge 270 near the side cover 300, and the side cover 300 is correspondingly provided with a second overlap edge 320.

[0041] In a preferred embodiment of the utility model, the inner diameter of the inner ring 220 is smaller than the inner diameter of the outer ring 230, and the air guide plate 240 connects the inner side of the inner ring 220 and the inner side of the outer ring 230, so that one side of the first port 251 is inclined toward the outer ring 230. Compared with the solution of making the first port 251 completely perpendicular to the light output lens 120, such a setting can make more gas pass through the air duct 250, thereby accelerating the ventilation efficiency of the air duct 250.

[0042] In a preferred embodiment of the present invention, the air duct 250 allows the airflow entering and exiting the air duct to flow around the periphery of the light output lens 120. This effectively dissipates heat for the light output lens 120 and prevents the light output lens 120 from fogging.
