Description

Technical Field

[0001] This utility model relates to the field of photographic auxiliary equipment technology, and more specifically to a supplementary lighting device for photographic shooting. Background Technology

[0002] In photography, lighting is a key factor in determining the shooting effect. Especially in outdoor nighttime environments, insufficient natural light directly affects the brightness, clarity, and color reproduction of the image. At this time, supplementary lighting devices (such as LED fill lights, portable flashes, etc.) have become core equipment for improving the image quality. They compensate for the lack of ambient light by actively emitting light, ensuring that the details of the subject are clear and the colors are accurately presented, meeting the needs of various nighttime shooting such as portrait close-ups, still life, and macro photography.

[0003] However, existing outdoor supplemental lighting devices have significant technical flaws: their light source wavelengths are mostly concentrated in the 380-500nm ultraviolet-blue violet light band. This band of light has a strong phototactic attraction to mosquitoes, causing a large number of mosquitoes to gather on and around the light guide plate of the lamp head during the shooting process. This problem will cause multiple negative effects: on the one hand, the gathered mosquitoes will be illuminated by the supplemental light, forming "mosquito ghosting", "light spot obstruction" or "dynamic afterimage" in the shooting image. Especially in close-up shooting scenes, mosquitoes directly become image interference elements, greatly reducing the purity of the image and increasing the difficulty of post-editing. On the other hand, a large number of mosquitoes attached to the surface of the light guide plate will block some of the supplemental light emission, destroying the uniformity of the supplemental light, causing problems such as "local dark areas" and "light scattering" on the subject, affecting the consistency of brightness and the accuracy of color reproduction. This results in undesirable effects such as "uneven highlights and messy shadows" in scenes that require uniform supplemental lighting, such as night scene portrait facial lighting. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a supplementary lighting device for photography to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a supplementary lighting device for photography, including a supplementary light body, a fixed cylinder fixedly sleeved on the outer surface of the supplementary light body tube, a fan fixedly installed at equal intervals inside the fixed cylinder, the input end of the fan extending to the outside of the fixed cylinder, an insect repellent fan rotating component installed on the surface of the fixed cylinder away from the fan, the output end of the insect repellent fan rotating component facing the surface of the light guide plate of the supplementary light body, and the input end of the insect repellent fan rotating component rotatably connected to the inside of the fixed cylinder.

[0006] Furthermore, the insect-repellent fan assembly includes an air outlet ring that fits and is connected to the surface of the fixed cylinder. The inner wall of the air outlet ring has air outlet holes equidistantly opened. An outer ring and a guide plate are fixedly connected to the surface of the air outlet ring near the fixed cylinder. An inner ring is fixedly connected to the inner wall of the outer ring at equal intervals. A positioning groove is opened on the outer surface of the outer ring. Steel balls are movably installed equidistantly inside the positioning groove. A sealing ring is fixedly sleeved on the outer surface of the outer ring. The outer surface of the sealing ring is rotatably connected to the inside of the fixed cylinder. The inside of the fixed cylinder is connected to the inside of the air outlet ring through the gap between the outer ring and the guide plate. The inside of the air outlet ring is connected to the outside of the air outlet ring through the air outlet holes.

[0007] Furthermore, an annular groove is formed on the surface of the fixed cylinder near the air outlet ring, the output end of the fan is connected to the inside of the annular groove, a limiting groove is formed on the inner wall of the annular groove, and the outer surface of the steel ball is rolled and connected to the inside of the limiting groove.

[0008] Furthermore, the outer surface of the sealing ring is rotatably connected to the inner wall of the annular groove, and the angle between the guide plate and the outer ring is fifteen degrees.

[0009] Furthermore, the outer diameter of the inner ring is smaller than the inner diameter of the outer ring, and both the outer ring and the inner ring are rotatably connected inside the annular groove.

[0010] Furthermore, a light-controlled switch is installed on the outer surface of the fixed cylinder, and the light-controlled switch controls the start and stop of the fan.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, through the synergistic action of the fan and the insect-repelling air-rotating component, can continuously deliver high-pressure airflow to the surface of the light guide plate of the main body of the supplementary light, forming a dynamic airflow barrier. This blocks mosquitoes from approaching at the source and blows off any attached mosquitoes in time. At the same time, the insect-repelling air-rotating component guides the airflow to rotate with the help of the guide plate, so that the airflow can cover the light guide plate 360° in all directions through the air outlet, completely eliminating shooting interference such as "mosquito ghosting" and "light spot obstruction", avoiding dynamic afterimages from affecting the image effect, greatly improving the purity of night shooting images, and reducing the workload and difficulty of post-editing. It is especially suitable for scenes with high requirements for image purity, such as portrait close-ups and macro photography.

[0013] 2. This utility model prevents mosquitoes from attaching to the light guide plate by using an airflow barrier, effectively avoiding the problems of "local dark areas" and "light scattering" caused by light blockage, ensuring that the supplementary light is always evenly distributed. At the same time, the light control switch can automatically control the fan to start and stop according to the ambient light, and accurately activate the insect repellent function when supplementing light at night. This does not affect the normal light emission of the supplementary light device, and can ensure that the brightness of the subject is consistent and the color reproduction is accurate. It solves the problem of "uneven brightness and messy shadows" caused by mosquito interference in existing outdoor supplementary light equipment, and significantly improves the stability and reliability of the supplementary light effect in night scene shooting.

Detailed Implementation

[0016] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0017] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0018] A supplementary lighting device for photography includes a supplementary light body 1. A fixed cylinder 2 is fixedly sleeved on the outer surface of the lamp tube of the supplementary light body 1. A fan 3 is fixedly installed at equal intervals inside the fixed cylinder 2. The input end of the fan 3 extends to the outside of the fixed cylinder 2. An insect repellent fan rotating component 4 is installed on the surface of the fixed cylinder 2 away from the fan 3. The output end of the insect repellent fan rotating component 4 faces the light guide plate surface of the supplementary light body 1. The input end of the insect repellent fan rotating component 4 is rotatably connected to the inside of the fixed cylinder 2.

[0019] In this implementation scheme, the fan 3 delivers airflow into the fixed cylinder 2, and the insect-repelling air-rotating component 4 is rotatably connected to the fixed cylinder 2 with its output end facing the light guide plate of the supplementary light body 1. The airflow can accurately act on the surface of the light guide plate. Through the synergy of the fan 3 and the insect-repelling air-rotating component 4, a continuous airflow barrier is formed, which effectively blocks mosquitoes from approaching and prevents mosquitoes from gathering on the surface of the light guide plate, thereby reducing mosquito interference during shooting from the source. At the same time, it does not affect the normal light emission angle and range of the supplementary light device, ensuring that the supplementary light function is not affected.

[0020] Specifically, the insect-repellent fan assembly 4 includes an air outlet ring 41 that is attached to the surface of the fixed cylinder 2. The inner wall of the air outlet ring 41 has air outlet holes 42 that are equidistantly opened. An outer ring 43 and a guide plate 45 are fixedly connected to the surface of the air outlet ring 41 near the fixed cylinder 2. An inner ring 44 is fixedly connected to the inner wall of the outer ring 43 at equal intervals. A positioning groove 46 is opened on the outer surface of the outer ring 43. Steel balls 47 are movably installed at equal intervals inside the positioning groove 46. A sealing ring 48 is fixedly sleeved on the outer surface of the outer ring 43. The outer surface of the sealing ring 48 is rotatably connected to the inside of the fixed cylinder 2. The inside of the fixed cylinder 2 is connected to the inside of the air outlet ring 41 through the gap between the outer ring 43 and the guide plate 45. The inside of the air outlet ring 41 is connected to the outside of the air outlet ring 41 through the air outlet holes 42.

[0021] In this embodiment, airflow can enter the air outlet ring 41 through the gap between the outer ring 43 and the guide plate 45, and be evenly sprayed out through the air outlet 42. The steel ball 47 reduces the frictional resistance when the outer ring 43 rotates, making the insect repellent wind turbine assembly 4 rotate more smoothly. The sealing ring 48 ensures the airflow is sealed and transmitted, avoiding the decrease in insect repellent effect caused by airflow leakage. At the same time, the design of multiple sets of air outlets 42 realizes multi-point coverage of airflow and improves the efficiency of blowing down mosquitoes.

[0022] Specifically, an annular groove 21 is provided on the surface of the fixed cylinder 2 near the air outlet ring 41, the output end of the fan 3 is connected to the inside of the annular groove 21, a limiting groove 22 is provided on the inner wall of the annular groove 21, and the outer surface of the steel ball 47 is rolled and connected to the inside of the limiting groove 22.

[0023] In this embodiment, the annular groove 21 provides buffer and diversion space for the airflow, so that the high-pressure airflow delivered by the fan 3 can be evenly distributed to the insect repellent air-rotating component 4. The limiting groove 22 plays a positioning role for the steel ball 47, preventing the insect repellent air-rotating component 4 from deviating when rotating, ensuring that the airflow is always accurately directed towards the light guide plate of the supplementary light body 1, and ensuring the stable formation of the 360° dynamic airflow barrier.

[0024] Specifically, the outer surface of the sealing ring 48 is rotatably connected to the inner wall of the annular groove 21, and the angle between the guide plate 45 and the outer ring 43 is fifteen degrees.

[0025] In this embodiment, the sealing ring 48 enhances the sealing performance between the fixed cylinder 2 and the insect repellent air rotating component 4, preventing airflow leakage from the connection and ensuring that the airflow pressure meets the insect repelling requirements. The 15-degree angled guide plate 45 can maximize the use of airflow thrust, driving the outer ring 43 and the air outlet ring 41 to rotate smoothly and efficiently, so that the airflow ejected from the air outlet 42 can cover the light guide plate in all directions, improving the comprehensiveness of insect repellency.

[0026] Specifically, the outer diameter of the inner ring 44 is smaller than the inner diameter of the outer ring 43, and both the outer ring 43 and the inner ring 44 are rotatably connected inside the annular groove 21.

[0027] In this embodiment, an airflow channel is formed between the outer ring 43 and the inner ring 44 to ensure that the airflow delivered by the fan 3 can pass smoothly and drive the component to rotate. At the same time, the double-ring structure enhances the stability of the insect repellent fan rotating component 4 when it rotates, avoids the shaking caused by uneven force on a single ring structure, ensures the uniformity of the airflow ejected from the air outlet 42, and thus improves the stability of the supplementary light.

[0028] Specifically, a light control switch 23 is installed on the outer surface of the fixed cylinder 2, and the light control switch 23 controls the opening and closing of the fan 3.

[0029] In this implementation scheme, the light control switch 23 can automatically determine whether to start the fan 3 according to the ambient light intensity. When no supplementary light is needed during the day, the fan 3 will automatically turn off to save energy. When supplementary light is needed at night, the insect repellent function will be accurately activated without manual operation. At the same time, it ensures that the fan 3 only works at night when mosquitoes are more likely to gather, thus extending the service life of the fan 3 and ensuring that the supplementary light device always maintains a uniform and stable supplementary light effect and accurate color reproduction when shooting at night.

[0030] The working principle and usage process of this utility model are as follows: When using it at night, after detection by the light control switch 23, the fan 3 is started. After the fan 3 is started, the high-pressure airflow enters the interior of the annular groove 21, and then enters between the outer ring 43 and the inner ring 44. Through the guidance of the guide plate 45, the outer ring 43 and the inner ring 44 are driven to rotate counterclockwise. Through the rotation of the outer ring 43 and the inner ring 44, the air outlet ring 41 is driven to rotate. The high-pressure airflow finally enters the interior of the air outlet ring 41, and then flows into the surface of the light guide plate of the supplementary light body 1 through the air outlet 42, which can clean up mosquitoes. With the rotation of the air outlet ring 41, high-pressure airflow can be sprayed from various angles, which can blow away larger insects.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
