Description

Technical Field

[0001] This utility model relates to the field of lighting devices, and in particular to a fish-raising lighting device with adjustable illumination range. Background Technology

[0002] Light plays a vital role in the growth of fish. It not only affects the fish's visual perception but also has a profound impact on their physiological rhythms and behavioral patterns. Lighting conditions also need to be considered in the process of raising fish artificially. Fish lighting devices are lighting equipment specially designed for fish enthusiasts, which can effectively provide a suitable lighting environment for aquatic organisms in the aquarium.

[0003] Current lighting devices typically consist of multiple LED lights, with the lighting range controlled by the movement of a light-shielding plate. However, the LED lights in the corresponding light-shielding sections are often not turned off in time, which may result in energy waste and generate redundant heat, increasing the burden on the heat dissipation system. In addition, although the device can adjust the illumination range, it may lack a structure for adjusting the light intensity. A fixed light intensity may disrupt the biological clock of fish, thereby affecting their normal growth.

[0004] Therefore, those skilled in the art have provided a fish-raising lighting device with adjustable illumination range to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable illumination range lighting device for fish farming. This lighting device can achieve linkage between the light-shielding structure and the LED light, and can also adjust the light intensity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fish-raising lighting device with adjustable illumination range includes a base, a protective frame fixedly installed near the periphery of the upper end of the base, a lighting mechanism installed near the center of the upper end of the base, and an adjustment mechanism installed inside the protective frame.

[0008] The lighting mechanism includes multiple lamp tubes, multiple filter films, and two operating frames. Lamp holders are fixedly installed on both sides of the multiple lamp tubes, and rings are fixedly connected to both sides of the multiple filter films. Extension rods are fixedly installed on opposite sides of each pair of the multiple rings.

[0009] The adjustment mechanism includes two fixed blocks, four motors, two diaphragms and multiple sensing blocks. Two fixed frames are fixedly fitted on opposite sides of the two fixed blocks, and rotating shafts are rotatably fitted inside the four fixed frames.

[0010] Furthermore, all of the lamp tubes are located inside the protective frame, and the multiple filter films are respectively rotatably sleeved on the outer surface of the multiple lamp tubes.

[0011] Furthermore, multiple lamp holders are fixedly mounted on the upper end of the base, and multiple rings are respectively rotatably fitted into multiple lamp holders.

[0012] Furthermore, the opposite ends of the multiple extension rods are respectively fitted into two operating frames, and the two operating frames are slidably arranged on both sides of the protective frame.

[0013] Furthermore, a heat dissipation mesh is provided at the lower end of the base, and both fixing blocks are fixedly installed inside the protective frame near the front and rear ends.

[0014] Furthermore, all four motors are fixedly installed inside the protective frame near the front and rear ends, and the output ends of the four motors are respectively fixedly connected to one side of the four rotating shafts.

[0015] Furthermore, both of the two films have a light-shielding coating on opposite ends, both films are located above the lamp tube, and both ends of the two films are fixedly connected to four rotating shafts, with the portions of the two films near their ends wrapped around the outer surfaces of the four rotating shafts.

[0016] Furthermore, multiple sensing blocks are fixedly installed on the inner surface of the protective frame near one side, and the positions of the multiple sensing blocks correspond one-to-one with the positions of the multiple lamp tubes. Photosensitive sensors are embedded at the upper and lower ends of the multiple sensing blocks, and the upper and lower ends of the multiple sensing blocks are respectively attached to two thin films.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model proposes an adjustable illumination range fish-raising lighting device. The lighting device is equipped with an adjustment mechanism. During use, half of the film is coated with a light-blocking coating to block the light. The two sides of the film are respectively wound around a rotating shaft. The synchronous rotation of the two rotating shafts is controlled by a motor to move the position of the coating and adjust the illumination range. At the same time, the photosensitive sensor on the sensing block can monitor the position of the coating in real time and control the lamps in the light-blocking area to turn off in time. In this way, the illumination range can be adjusted and the waste of electricity can be effectively reduced.

[0019] 2. This utility model proposes an adjustable illumination range fish-raising lighting device. The lighting device is equipped with a lighting mechanism. During use, a filter film is wrapped around the outside of the lamp tube. Half of the filter film is highly transparent and the other half is less transparent. Under the restriction of the elongated slide and the arc-shaped slide, the up and down movement of the operating frame can drive the extension rod to make an arc-shaped movement along the arc-shaped slide, thereby causing the filter film to rotate. In this way, the light intensity can be adjusted to simulate the day and night light environment in nature, ensuring that the fish maintain normal biological rhythms, thereby promoting their healthy growth.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2An embodiment of this utility model is provided: a fish-raising lighting device with adjustable illumination range, including a base 1, a protective frame 2 fixedly installed on the upper end of the base 1 near the periphery, a lighting mechanism 3 installed on the upper end of the base 1 near the middle, an adjustment mechanism 4 installed inside the protective frame 2, and a heat dissipation mesh opened at the lower end of the base 1.

[0030] Specifically, the base 1 and the protective frame 2 form the external structure of the entire device. The lower end of the base 1 is equipped with a heat dissipation mesh, and the mesh holes can promote the dissipation of heat when the lighting device is running. The upper surface of the protective frame 2 is a transparent frame, which does not block the internal light and allows the internal light to shine outward. When using the lighting device, the side of the protective frame 2 with the transparent frame faces the fish tank for easy lighting of the fish tank. The lighting mechanism 3 is the structure that provides light and can also adjust the intensity of the light. The adjustment mechanism 4 can adjust the lighting range.

[0031] Reference Figure 2-6 The lighting mechanism 3 includes multiple lamp tubes 301, multiple filter films 303 and two operating frames 306. Lamp holders 302 are fixedly installed on both sides of the multiple lamp tubes 301. Rings 304 are fixedly connected to both sides of the multiple filter films 303. Extension rods 305 are fixedly installed on opposite sides of each pair of rings 304.

[0032] Multiple lamp tubes 301 are located inside the protective frame 2. Multiple filter films 303 are rotatably sleeved on the outer surface of multiple lamp tubes 301. Multiple lamp holders 302 are fixedly installed on the upper end of the base 1. Multiple rings 304 are rotatably sleeved in multiple lamp holders 302. Multiple extension rods 305 are sleeved in two operating frames 306 at opposite ends. The two operating frames 306 are slidably installed on both sides of the protective frame 2.

[0033] Specifically, the lamp tube 301 is a structure that provides light. Its switch is controlled by two switches: one is the switch that controls the on / off state of the lamp tube 301's own control circuit, and the other is the light-detecting sensor block 406. When the former is on, the sensor block 406 will control the lamp tube 301 to turn on or off after detecting a specified signal. The lamp holder 302 has two functions: one is to support and fix the lamp tube 301, so that the lamp tube 301 is in a suspended state, which facilitates the application of the filter film 303; the other is to fix the filter film 303. The rings 304 at both ends of the filter film 303 are fitted in the lamp holder 302, which can not only stably fit the filter film 303 on the outer surface of the corresponding lamp tube 301, but also ensure the rotation of the filter film 303. Furthermore, the opposite sides of the lamp holder 302 are provided with arc-shaped sliding grooves for the extension rod 305 to slide.

[0034] The filter film 303 is in the shape of a horizontal cylinder, and the light transmittance of the upper and lower parts of the filter film 303 is different. The light intensity can be adjusted through the function of the filter film 303. The ring 304 is divided into two sections. The outer diameter of one section is larger, which can ensure that the ring 304 is stably locked in the lamp holder 302 and prevent it from falling out of the lamp holder 302 during the rotation of the ring 304. The outer diameter of the other section is smaller, which is adapted to the size of the filter film 303.

[0035] The operating frame 306 is a frame structure, with its middle part slidingly fitted on both sides of the protective frame 2. One part is located outside the protective frame 2 for easy user operation, and the other part is located inside the inner wall of the protective frame 2. Multiple elongated grooves are opened on its surface. The height of the grooves is the same as the diameter of the extension rod 305, which can ensure that the extension rod 305 slides back and forth in them. The extension rod 305 is fitted in both the arc-shaped groove and the elongated groove. Its position is affected by both grooves. The up and down movement of the elongated groove drives the up and down movement of the extension rod 305. The arc-shaped groove ensures that the extension rod 305 moves downward in the vertical direction while driving the ring 304 to rotate.

[0036] Reference Figure 2-5 The adjustment mechanism 4 includes two fixed blocks 401, four motors 404, two diaphragms 405 and multiple sensing blocks 406. Two fixed frames 402 are fixedly sleeved on opposite sides of the two fixed blocks 401, and rotating shafts 403 are rotatably sleeved inside the four fixed frames 402.

[0037] Two fixing blocks 401 are fixedly installed inside the protective frame 2 near the front and rear ends. Four motors 404 are fixedly installed inside the protective frame 2 near the front and rear ends. The output ends of the four motors 404 are fixedly connected to one side of the four rotating shafts 403 respectively. Two films 405 are provided with a full light-shielding coating on opposite ends. The two films 405 are located above the lamp tube 301. The two ends of the two films 405 are fixedly connected to the four rotating shafts 403 respectively. The parts of the two films 405 near the two ends are respectively wrapped around the outer surface of the four rotating shafts 403.

[0038] Multiple sensor blocks 406 are fixedly installed on the inner surface of the protective frame 2 near one side. The positions of the multiple sensor blocks 406 correspond one-to-one with the positions of the multiple lamp tubes 301. Photosensitive sensors are embedded at the upper and lower ends of the multiple sensor blocks 406. The upper and lower ends of the multiple sensor blocks 406 are respectively attached to two thin films 405.

[0039] Specifically, the purpose of the fixing block 401 is to fix the two fixing frames 402 on the same side. The fixing frame 402 can hold the film 405 on one hand, and position the rotating shaft 403 on the other hand, so that it can only rotate in a fixed position. Each rotating shaft 403 is equipped with a motor 404. The motor 404 can drive the rotating shaft 403 to rotate, thereby winding the film 405. The two ends of a film 405 are fixedly connected to the outer surfaces of the two rotating shafts 403 respectively. The two motors 404 at the same height are controlled by the same controller, and their rotation direction and rotation speed are the same, ensuring that the film 405 is always in a suitable tightness during the adjustment process.

[0040] Each film 405 is divided into two parts. One part is coated with a light-blocking coating to block light, while the other part is uncoated to allow all light to pass through. The two films 405 are coated in different positions, one near the front end and the other near the rear end. Only when the uncoated areas of the two films 405 overlap can the light below that area shine outward. By changing the relative position of the two films 405, the position and size of the illumination area of ​​the device can be adjusted.

[0041] Furthermore, when the coated film 405 is located above the lamp tube 301, it is in contact with the sensing block 406. The coating of the upper film 405 is located at the top, and the coating of the lower film 405 is located at the bottom. This avoids damage to the coating caused by friction with the sensing block 406 during adjustment, which would affect the detection results of the sensing block 406 and the adjustment effect of the device. Photosensitive sensors are embedded at both the top and bottom of the sensing block 406, which can be used to detect the light conditions at the top and bottom of the sensing block 406, and thus determine the position of the coating on the film 405. There is a feedback mechanism between the sensing block 406 and the lamp tube 301. When the coated film 405 is in contact with the sensing block 406, the photosensitive sensor will detect the relevant signal in time. As long as one of the two photosensitive sensors on the sensing block 406 detects a light-blocking signal, it will feed back the corresponding signal to control the circuit of the lamp tube 301, thereby turning off the lamp tube 301 located at the bottom of the sensing block 406, so as to save energy.

[0042] Working principle: When it is necessary to simulate dim lighting conditions at night, pull down the operating frames 306 on both sides at the same time. The elongated slide on the operating frame 306 also moves down. During the downward movement, it exerts downward pressure on the extension rod 305. Due to the limiting effect of the arc-shaped slide on the lamp holder 302, the extension rod 305 can only slide down along the arc-shaped slide. The certain length of the elongated slide can ensure the smooth sliding of the extension rod 305 until the extension rod 305 moves to the lowest position. The sliding of the extension rod 305 along the arc-shaped slide can drive the ring 304 to rotate around the center. The filter film 303 between the two rings 304 rotates accordingly, causing the part with poor light transmittance on the filter film 303 to rotate above the lamp tube 301, thereby reducing the light intensity and completing the adjustment of the light intensity.

[0043] When the illumination range of the device needs to be adjusted, the switch of lamp tube 301 is turned on, and two motors 404 at the same height are started, so that two rotating shafts 403 at the same height rotate synchronously and in the same direction, moving the position of the coating on the film 405 horizontally. There is a dividing line between the coated and uncoated areas on the film 405. The dividing line of the two films 405 is moved to the appropriate position. At this time, there is an overlapping area between the uncoated areas of the two films 405. This area is the required illumination range. Multiple sensing blocks 406 on the inner wall of the protective frame 2 monitor the position of the light-shielding coating on the film 405 through photosensitive sensors. When one of the photosensitive sensors at the upper or lower end of the sensing block 406 detects a dark signal, it feeds back to the circuit that controls the corresponding lamp tube 301 below it, so that lamp tube 301 is turned off, leaving only the lamp tube 301 corresponding to the illumination range on, which saves energy.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
