Description

Technical Field

[0001] This invention relates to the field of infrared fill light technology, and more specifically, to an infrared fill light and its mounting platform. Background Technology

[0002] Common supplementary lighting for surveillance cameras includes several types: strobe, constant light, infrared, white light, and flash. Among these, constant light and infrared are particularly effective for supplementary lighting in surveillance. Infrared lights for night vision surveillance can serve as auxiliary lighting for monitoring equipment. In the absence of other lighting at night, infrared lights can provide supplementary light to the monitoring equipment, allowing it to capture images of objects.

[0003] Existing infrared supplementary lights for surveillance are mostly fixedly installed as an integral part of the surveillance equipment. If the surveillance still cannot capture a clear image after supplementing the light, the infrared supplementary light cannot be moved to adjust the supplementary light effect, resulting in poor applicability. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides an infrared supplementary light and its installation platform, aiming to improve the problem that existing infrared supplementary lights for monitoring are basically fixedly installed directly as an integral part of the monitoring equipment. When the monitoring still cannot capture clear images after supplementary lighting, the infrared supplementary light cannot be moved to adjust the supplementary lighting effect, resulting in poor applicability.

[0005] This invention is implemented as follows: The present invention provides an infrared fill light, including a camera mechanism and a first fill light mechanism.

[0006] The camera mechanism includes an outer shell, an inner cylinder, and a camera. The inner cylinder is fixed inside the outer shell, and the camera is installed inside the inner cylinder.

[0007] The first supplementary lighting mechanism includes a driving component, a supplementary lighting frame, and a first infrared supplementary light. The driving component is fixed to the inner wall of the outer shell, the supplementary lighting frame is slidably sleeved on the inner cylinder, the piston rod end of the driving component is fixedly connected to the outer wall of the supplementary lighting frame, and the first infrared supplementary light is fixed to the inner cavity of the supplementary lighting frame.

[0008] In one embodiment of the present invention, the camera mechanism further includes a light shield fixed to the housing.

[0009] In one embodiment of the present invention, the light shield includes a shield body and a first dustproof net, the shield body being fixed to the outer shell, and the first dustproof net being disposed between the inner wall of the shield body and the outer wall of the outer shell.

[0010] In one embodiment of the present invention, the bottom front end of the cover is chamfered.

[0011] In one embodiment of the present invention, the outer wall of the inner cylinder is provided with a slide rail, and the inner wall of the fill light frame is slidably connected to the slide rail.

[0012] In one embodiment of the present invention, the slide rails are arranged in annularly at equal intervals on the outer wall of the inner cylinder, and the slide rails are in contact with but not connected to the supplementary lighting frame.

[0013] In one embodiment of the present invention, the slide rail includes a guide rail and a limiting plate. The guide rail is fixed to the outer wall of the inner cylinder, the fill light frame is slidably connected to the guide rail, and the limiting plate is fixed to the end of the guide rail.

[0014] In one embodiment of the present invention, the first supplementary lighting mechanism further includes a light-transmitting plate, which is fixed on the supplementary lighting frame.

[0015] In one embodiment of the present invention, the inner wall of the light-transmitting plate is slidably connected to the guide rail.

[0016] This application also provides a building management measurement device, including the aforementioned infrared supplementary light and a mounting base, wherein the housing is hinged to the mounting base.

[0017] In related technologies, supplementary lighting is provided by a first infrared supplementary light. As the driving component moves the first infrared supplementary light, the supplementary light intensity is increased by shortening the actual illumination distance, but the supplementary light range is also reduced. The first infrared supplementary light is difficult to supplement the edge of the camera's field of view, resulting in poor edge image shooting effect.

[0018] The infrared supplementary light provided by the present invention further includes a second supplementary light mechanism. The second supplementary light mechanism includes a fixed frame, a slider, a first connecting rod, a second infrared supplementary light, a second connecting rod, and a third connecting rod. The fixed frame is fixed on the supplementary light frame, and the slider is slidably disposed on the fixed frame. The two ends of the first connecting rod are respectively hinged to the outer wall of the inner cylinder and one side of the slider. The two ends of the second connecting rod are respectively hinged to the other side of the slider and one end of the second infrared supplementary light. The two ends of the third connecting rod are respectively hinged to the other end of the second infrared supplementary light and the inner cavity of the supplementary light frame.

[0019] In use, the driving component extends a piston rod to move the fill light frame, shortening the distance between the first and second infrared fill lights and the target object, thus increasing the fill light intensity. During the movement of the fill light frame, the slider slides along the axis of the fill light frame on the fixed frame under the pulling force of the first connecting rod. Since the front end of the second infrared fill light is directly hinged to the inner cavity side wall of the fill light frame, the slider will exert a pushing force on the rear end of the second infrared fill light through the second connecting rod when it moves, causing it to rotate around the hinge point between itself and the fill light frame, thereby adjusting the illumination angle of the second infrared fill light. By adopting the above scheme, the fill light intensity can be increased by shortening the refraction distance, while the fill light angle can be adjusted, thereby providing fill light to the edge of the camera's field of view and improving the shooting effect.

[0020] In one embodiment of the present invention, the slider includes a slider body and an ear plate, the slider body is slidably disposed on the fixed frame, and the ear plate is fixed to the side of the slider body.

[0021] In one embodiment of the present invention, the ear plate is provided with a mounting groove, and ball bearings are arranged in the mounting groove. A corresponding sliding groove is provided on the fixing frame, and the ball bearings contact the inner wall of the sliding groove but are not connected.

[0022] In related technologies, as the second supplementary lighting mechanism starts working, the heat generated by the supplementary lighting component is higher than that generated when only the first supplementary lighting mechanism is used. Relying solely on the heat conduction of the outer casing for heat dissipation is inefficient. If the heat cannot be dissipated in time, it will accelerate component wear and affect the service life of the equipment.

[0023] The present invention provides an infrared supplementary light, which further includes a heat dissipation mechanism. The heat dissipation mechanism includes a mounting plate, a cooling fan, a heat dissipation frame, a sealing plate, a fixing rod, and a fourth connecting rod. The mounting plate is fixed between the inner wall of the outer shell and the outer wall of the inner cylinder. The cooling fan is mounted on the mounting plate. A first air inlet is provided through the outer shell, and a second dustproof mesh is provided inside the first air inlet. A second air inlet is correspondingly provided on the supplementary light frame. An air outlet is provided through the side of the supplementary light frame. The heat dissipation frame is located at the bottom of the rear end of the inner cavity of the outer shell. The sealing plate is hinged to the bottom of the heat dissipation frame. The fixing rod is fixed to one side of the supplementary light frame and is slidably disposed through the mounting plate. The two ends of the fourth connecting rod are respectively hinged to the end of the fixing rod and the upper surface of the sealing plate.

[0024] In use, as the driving component extends the piston rod, it moves the fill light frame. The fixed rod follows the fill light frame and then applies a downward force to the sealing plate through the fourth connecting rod, causing the sealing plate to rotate and open. The cooling fan starts, and cold air from the outside enters the inner cavity of the fill light frame through the first and second air inlets under the suction of the cooling fan. The hot air inside the fill light frame moves through the air outlet to the space between the mounting plate and the fill light frame. The cooling fan then extracts the hot air and discharges it to the other side of the mounting plate. The hot air then passes through the heat dissipation frame and is discharged to the outside, completing the heat exchange. With the above scheme, the heat dissipation frame can automatically open when the second fill light mechanism is working, improving the heat dissipation efficiency of the equipment and extending its service life.

[0025] In one embodiment of the present invention, multiple air outlets are provided, and the multiple air outlets are arranged in a ring at equal intervals on the fill light frame.

[0026] In one embodiment of the present invention, the heat dissipation mechanism further includes a third dustproof mesh, which is disposed on the heat dissipation frame and has an opening for the fourth connecting rod to move.

[0027] The beneficial effects of the present invention are as follows: The infrared supplementary light and its installation platform obtained by the present invention, when used, when it is detected that the monitoring brightness in the field of view of the camera is still insufficient under the supplementary light of the first infrared supplementary light, the driving component is activated, the piston rod is extended to drive the supplementary light frame to move, shortening the distance from the first infrared supplementary light to the target, thereby improving the supplementary light intensity and enhancing the monitoring and shooting effect, and has strong applicability.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] Example Please see Figures 1-13 The present invention provides an infrared supplementary light, including a camera mechanism 100 and a first supplementary light mechanism 200. The first supplementary light mechanism 200 is disposed on the camera mechanism 100. The camera mechanism 100 monitors the field of view, and the first supplementary light mechanism 200 is used to supplement the shooting field of view, thereby improving the shooting effect of the camera mechanism 100.

[0034] Please see Figure 2 and Figure 3 The camera mechanism 100 includes a housing 110, an inner cylinder 120, and a camera 130. The inner cylinder 120 is fixed inside the housing 110, and the camera 130 is installed inside the inner cylinder 120.

[0035] It should be noted that the camera mechanism 100 also includes a light shield 140, which is fixed to the outer shell 110. On the one hand, it is used to block light from outside the field of view from above, so as to prevent the interference light from the surrounding environment from shining directly into the camera 130. On the other hand, it can protect the outer shell 110 from foreign objects falling and damaging the outer shell 110. The light shield 140 includes a cover body 141 and a first dustproof net 142. The cover body 141 is fixed to the outer shell 110. The bottom front end of the cover body 141 is beveled to prevent obstruction of the monitoring field of view and light. There is a gap between the inner wall of the cover body 141 and the outer wall of the outer shell 110, which can be used to dissipate heat from the outer shell 110 with the help of air. The first dustproof net 142 is set between the inner wall of the cover body 141 and the outer wall of the outer shell 110 to prevent foreign objects from entering the gap and affecting the airflow.

[0036] Please see Figures 4-6The first supplementary lighting mechanism 200 includes a driving component 210, a supplementary lighting frame 220, and a first infrared supplementary light 230. The driving component 210 is fixed to the inner wall of the outer shell 110. The driving component 210 can be an electric push rod. Multiple driving components 210 are provided and are arranged in a ring at equal intervals on the outer shell 110. While increasing the driving force, the supplementary lighting frame 220 is evenly stressed. The supplementary lighting frame 220 is slidably sleeved on the inner cylinder 120. The piston rod end of the driving component 210 is fixedly connected to the outer wall of the supplementary lighting frame 220. The first infrared supplementary light 230 is fixed in the inner cavity of the supplementary lighting frame 220 and is arranged in a ring at equal intervals in the inner cavity of the supplementary lighting frame 220 to ensure the intensity and uniformity of the supplementary light.

[0037] When in use, if the brightness of the camera's field of view is still insufficient under the supplementary lighting effect of the first infrared supplementary light 230, the drive unit 210 is activated, and the piston rod extends to move the supplementary light frame 220, shortening the distance between the first infrared supplementary light 230 and the target, thereby increasing the supplementary light intensity and enhancing the monitoring and shooting effect.

[0038] It should be noted that the outer wall of the inner cylinder 120 is provided with a slide rail 240, and the inner wall of the fill light frame 220 is slidably connected to the slide rail 240, which improves the stability of the fill light frame 220 when sliding. The slide rail 240 is arranged in a ring at equal intervals on the outer wall of the inner cylinder 120. The slide rail 240 contacts the fill light frame 220 but is not connected. The slide rail 240 includes a guide rail 241 and a limiting plate 242. The guide rail 241 is fixed to the outer wall of the inner cylinder 120, the fill light frame 220 is slidably connected to the guide rail 241, and the limiting plate 242 is fixed to the end of the guide rail 241 to limit the maximum movable distance of the fill light frame 220.

[0039] It should be noted that the first supplementary lighting mechanism 200 also includes a light-transmitting plate 250, which is an annular plate. The light-transmitting plate 250 is fixed on the supplementary lighting frame 220 to protect the first infrared supplementary light 230 and prevent foreign objects from entering the inner cavity of the supplementary lighting frame 220 and blocking the first infrared supplementary light 230. The inner wall of the light-transmitting plate 250 is slidably connected to the guide rail 241, and the inner wall of the light-transmitting plate 250 and the guide rail are fitted with a clearance.

[0040] This application also provides a building management measurement device, including the above-mentioned infrared supplementary light and a mounting base 300. The mounting base 300 can be fixed to the mounting point by screws or other locking components, and the outer shell 110 is hinged to the mounting base 300.

[0041] In related technologies, supplementary lighting is provided by a first infrared supplementary light 230. As the driving component 210 moves the first infrared supplementary light 230, the supplementary light intensity is increased by shortening the actual illumination distance, while the supplementary light range is also reduced. The first infrared supplementary light 230 is unable to provide supplementary lighting to the edge of the field of view of the camera 130, resulting in poor edge image shooting effect.

[0042] Please see Figures 7-11 The infrared supplementary light provided by the present invention also includes a second supplementary light mechanism 400. The second supplementary light mechanism 400 includes a fixed frame 410, a slider 420, a first connecting rod 430, a second infrared supplementary light 440, a second connecting rod 450, and a third connecting rod 460. The fixed frame 410 is fixed on the supplementary light frame 220, and the slider 420 is slidably disposed on the fixed frame 410. The two ends of the first connecting rod 430 are respectively hinged to the outer wall of the inner cylinder 120 and one side of the slider 420. The two ends of the second connecting rod 450 are respectively hinged to the other side of the slider 420 and one end of the second infrared supplementary light 440. The two ends of the third connecting rod 460 are respectively hinged to the other end of the second infrared supplementary light 440 and the inner cavity of the supplementary light frame 220.

[0043] In use, the drive unit 210 extends the piston rod to move the fill light frame 220, shortening the distance between the first infrared fill light 230 and the second infrared fill light 440 and the target object, thus increasing the fill light intensity. During the movement of the fill light frame 220, the slider 420 slides on the fixed frame 410 towards the axis of the fill light frame 220 under the pulling force of the first connecting rod 430. Since the front end of the second infrared fill light 440 is directly hinged to the inner cavity side wall of the fill light frame 220, the slider 420 will apply a pushing force to the rear end of the second infrared fill light 440 through the second connecting rod 450 when it moves, causing the entire slider to rotate around the hinge point between itself and the fill light frame 220, thereby adjusting the illumination angle of the second infrared fill light 440. By adopting the above scheme, the fill light intensity can be increased by shortening the refraction distance, while the fill light angle can be adjusted, thereby providing fill light to the edge of the field of view of the camera 130 and improving the shooting effect.

[0044] It should be noted that the slider 420 includes a slider body 421 and an ear plate 422. The slider body 421 is slidably mounted on the fixed frame 410. The ear plate 422 is fixed to the side of the slider body 421 to prevent the slider body 421 from detaching from the fixed frame 410. The ear plate 422 has an installation groove 423. Ball bearings 424 are arranged in the installation groove 423. The ball bearings 424 can only rotate within the installation groove 423 under the action of friction. Adjacent ball bearings 424 are in contact with each other but not connected. The fixed frame 410 has a corresponding sliding groove 411. The length of the sliding groove 411 is greater than that of the installation groove 423. The ball bearings 424 are in contact with the inner wall of the sliding groove 411 but are not connected.

[0045] In related technologies, as the second supplementary lighting mechanism 400 starts working, the heat generated by the supplementary lighting component is higher than that generated when only the first supplementary lighting mechanism 200 is used. The heat dissipation is low by relying solely on the heat conduction of the outer casing 110. If the heat cannot be dissipated in time, it will accelerate component wear and affect the service life of the equipment.

[0046] Please see Figure 12 and Figure 13The infrared supplementary light provided by the present invention also includes a heat dissipation mechanism 500, which includes a mounting plate 510, a cooling fan 520, a heat dissipation frame 530, a sealing plate 540, a fixing rod 550, and a fourth connecting rod 560. The mounting plate 510 is fixed between the inner wall of the outer shell 110 and the outer wall of the inner cylinder 120. The cooling fan 520 is mounted on the mounting plate 510. A first air inlet 111 is provided through the outer shell 110, and a second air inlet 111 is provided inside the first air inlet 111. The dustproof net 112 and the supplementary lighting frame 220 are respectively provided with a second air inlet 113. The supplementary lighting frame 220 is provided with an air outlet 221 through the side. The heat dissipation frame 530 is located at the bottom of the rear end of the inner cavity of the outer shell 110. The sealing plate 540 is hinged to the bottom of the heat dissipation frame 530. The fixing rod 550 is fixed to one side of the supplementary lighting frame 220. The fixing rod 550 is slidably provided through the mounting plate 510. The two ends of the fourth connecting rod 560 are respectively hinged to the end of the fixing rod 550 and the upper surface of the sealing plate 540.

[0047] In use, as the driving component 210 extends its piston rod, it drives the fill light frame 220 to move. The fixed rod 550 moves along with the fill light frame 220, and then the fourth connecting rod 560 applies a downward force to the sealing plate 540, causing the sealing plate 540 to rotate and open. The cooling fan 520 starts, and the outside cold air enters the inner cavity of the fill light frame 220 through the first air inlet 111 and the second air inlet 113 under the suction of the cooling fan 520. The hot air in the inner cavity of the fill light frame 220 moves through the air outlet 221 to the space between the mounting plate 510 and the fill light frame 220. The cooling fan 520 then extracts the hot air and discharges it to the other side of the mounting plate 510. The hot air then passes through the heat dissipation frame 530 and is discharged to the outside, completing the heat exchange. With the above scheme, the heat dissipation frame 530 can automatically open when the second fill light mechanism 400 is working, which improves the heat dissipation efficiency of the equipment and extends the service life of the equipment.

[0048] It should be noted that there are multiple air outlets 221, which are arranged in a ring at equal intervals on the fill light frame 220 to improve heat dissipation efficiency.

[0049] It should be noted that the heat dissipation mechanism 500 also includes a third dustproof net 570, which is installed on the heat dissipation frame 530 to prevent foreign objects from entering the inner cavity of the outer shell 110 through the heat dissipation frame 530 during the operation of the heat dissipation mechanism 500. The third dustproof net 570 has an opening for the fourth connecting rod 560 to move.

[0050] It should be noted that the operation of the camera 130, driver 210, first infrared fill light 230, second infrared fill light 440 and cooling fan 520 can be controlled by a remote control center, or their operation can be controlled by installing sensor control elements inside the device.

[0051] Specifically, the working principle of this infrared supplementary light and its mounting platform is as follows: During use, when the brightness of the camera's field of view is still insufficient under the supplementary lighting effect of the first infrared supplementary light 230, the drive unit 210 is activated, extending the piston rod to move the supplementary light frame 220, shortening the distance between the first infrared supplementary light 230 and the target, thereby increasing the supplementary light intensity. During the movement of the supplementary light frame 220, the slider 420 slides along the axis of the supplementary light frame 220 on the fixed frame 410 under the pulling force of the first connecting rod 430. Since the front end of the second infrared supplementary light 440 is directly hinged to the inner cavity sidewall of the supplementary light frame 220, the slider 420, when moving, will exert a pushing force on the rear end of the second infrared supplementary light 440 through the second connecting rod 450, causing it to rotate around the hinge between itself and the supplementary light frame 220. The contact rotates, thereby adjusting the illumination angle of the second infrared fill light 440; as the driving component 210 extends the piston rod to drive the fill light frame 220 to move, the fixing rod 550 moves with the fill light frame 220, and then the fourth connecting rod 560 applies a downward force to the sealing plate 540, causing the sealing plate 540 to rotate and open, the cooling fan 520 starts, and the outside cold air enters the inner cavity of the fill light frame 220 through the first air inlet 111 and the second air inlet 113 under the suction of the cooling fan 520. The hot air in the inner cavity of the fill light frame 220 moves through the air outlet 221 to the space between the mounting plate 510 and the fill light frame 220, and then the cooling fan 520 draws out the hot air and discharges it to the other side of the mounting plate 510. The hot air then passes through the heat dissipation frame 530 and is discharged to the outside, completing the heat exchange.

[0052] It should be noted that the specific models and specifications of the camera 130, driver 210, first infrared fill light 230, second infrared fill light 440 and cooling fan 520 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0053] The power supply and operating principle of the camera 130, driver 210, first infrared fill light 230, second infrared fill light 440 and cooling fan 520 are clear to those skilled in the art and will not be described in detail here.

[0054] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
