[0043] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0044] In order to solve the problems in the prior art, the present application provides a camera for reducing interference from flying insects, wherein the lens assembly and the fill light assembly are arranged in a horizontal direction, and in the direction of the optical axis, the lens assembly is located at the front end of the fill light assembly, thereby reducing the flying insects attracted by the fill light assembly from appearing within the field of view of the lens assembly.

[0045] As shown in FIG1 to FIG3b , an embodiment of the present application provides a camera for reducing interference from flying insects, comprising:

[0046] The fuselage 10 is formed as a rectangular parallelepiped with a cavity inside, and an opening 11 is formed at the front end in the length direction. The opening 11 is formed in a rectangular shape with a width greater than a height, wherein the length direction and the width direction of the opening 11 both extend in the horizontal direction, and the edge of the opening 11 forms a fixed end face in a rectangular shape; for ease of understanding, a three-dimensional coordinate system is established with the long side direction of the opening 11, that is, the width direction of the fuselage, as the X-axis, the short side direction, that is, the height direction of the fuselage, as the Z-axis, and the direction perpendicular to the long side direction and the short side direction as the Y-axis, that is, the length direction of the fuselage.

[0047] A front cover 20 is mounted on a fixed end surface of the opening 11 via a first fastener 21 to seal the cavity, wherein the first fastener 21 is connected to the four corners of the opening 11 and the middle portions of a pair of long sides extending along the width direction (X-axis direction);

[0048] The lens assembly 30 is mounted on the front cover 20 from the inside via the first fixing sheet metal 71 so as to be located within the cavity. The optical axis of the lens assembly 30 is aligned with the longitudinal direction (Y-axis direction) and faces the front of the front cover 20. The lens assembly 30 is enclosed within the first fixing sheet metal 71.

[0049] A fill light assembly 40 is mounted on the front cover 20 from the inside so as to be located within the cavity. The light emission direction of the fill light assembly 40 is consistent with the length direction. The fill light assembly 40 has a light emission surface 43 that is flush with the front cover 20 or protrudes from the front cover 20 to provide auxiliary light through the light emission surface 43 toward the field of view of the lens assembly 30;

[0050] The motherboard assembly 33 is mounted on the front cover 20 from the inside via a second fixing sheet metal 72, positioned within the cavity. Specifically, the second fixing sheet metal 72 is detachably connected to the front cover 20, and the motherboard assembly 33 is fixed to the side of the second fixing sheet metal 72 facing away from the lens assembly 30. The second fixing sheet metal is sleeved onto the outside of the first fixing sheet metal 71, and the motherboard assembly 33 is fixed to the outer surface of the second fixing sheet metal 72, so that the motherboard assembly 33 is positioned directly behind the lens assembly 30 in the longitudinal direction. Specifically, as shown in Figure 1, the first fixed sheet metal 71 and the second fixed sheet metal 72 are respectively U-shaped structures, the openings of the first fixed sheet metal 71 and the second fixed sheet metal 72 are both facing the lens assembly 30, and the two are cross-arranged, so that the first fixed sheet metal 71 and the second fixed sheet metal 72 form an accommodating space opening toward the lens assembly 30, and the lens assembly 30 is located in the accommodating space, the first fixed sheet metal 71 and the second fixed sheet metal 72 respectively have an outward-turned first connecting portion 713 and a second connecting portion 723, the first fixed sheet metal 71 is detachably connected to the front cover 20 through the first connecting portion 713, and the second fixed sheet metal 72 is detachably connected to the front cover 20 through the second connecting portion 723.

[0051] As shown in Figure 1, the lens assembly 30 and the fill light assembly 40 are arranged on the front cover 20 along the horizontal direction (that is, the X-axis direction), wherein a pair of first fasteners 21 connected to the middle of a pair of long sides extending along the width direction (that is, the X-axis direction) are located between the lens assembly 30 and the fill light assembly 40.

[0052] In a specific example, as shown in FIG1 and FIG8 , the first fixing sheet metal 71 includes a first fixing plate 711 and a pair of first fixing arms 712 connected to a pair of opposite first side edges of the first fixing plate 711 . The first fixing arms 712 extend along the length direction, and the front ends of the first fixing arms 712 are connected to the inner surface of the front cover 20 .

[0053] The second fixing sheet metal 72 includes a second fixing plate 721 and a pair of second fixing arms 722 connected to a pair of opposite second side edges of the second fixing plate 721. The second fixing arms 722 extend along the length direction. The front ends of the second fixing arms 722 are connected to the front cover 20. The second side edges are perpendicular to the first side edges. The length of the second fixing arms 722 is greater than that of the first fixing arms 712. The length of the second side edges is greater than or equal to that of the first side edges.

[0054] The lens assembly 30 is installed in a space enclosed by the first fixing arm 712 , the second fixing arm 722 , and the first fixing plate 711 .

[0055] As shown in Figure 1, the first fixed sheet metal 71 and the second fixed sheet metal 72 both form a U-shaped bracket structure, and the first fixed sheet metal 71 and the second fixed sheet metal 72 are arranged at an angle difference of 90°, and the first fixed plate 711 and the second fixed plate 721 are arranged in parallel in a coaxial manner, so that the first fixed sheet metal 71 and the second fixed sheet metal 72 can be combined to form a hollow rectangular parallelepiped, wherein the lens assembly 30 is located inside the rectangular parallelepiped, and the mainboard assembly 33 is located on the outer surface of the rectangular parallelepiped, that is, the rectangular parallelepiped formed by the first fixed sheet metal 71 and the second fixed sheet metal 72, so that the lens assembly 30 and the mainboard assembly 33 can be compactly arranged in the cavity of the fuselage 10.

[0056] Since the lens assembly 30, the fill light assembly 40, and the main board assembly 33 all need to be installed on the front cover 20, the coaxial alignment fixing method of the lens assembly 30 and the main board assembly 33 can reduce the size of the front cover 20. That is, the front cover 20 only needs to meet the installation width required by the lens assembly 30 and the fill light assembly 40, and there is no need to set the installation space required for the lens assembly 30, the fill light assembly 40, and the main board assembly 33 in parallel at the same time, which has a significant effect on reducing the size of the body.

[0057] Furthermore, signal cables are inevitably required between the lens assembly 30, the fill light assembly 40, and the mainboard assembly 33. If these three components were arranged side by side, the internal wiring layout would be significantly more complex. However, using a coaxially aligned fixing method for the lens assembly 30 and the mainboard assembly 33 can at least reduce the impact of the cable layout on the internal layout complexity by shortening the distance between the lens assembly 30 and the mainboard assembly 33.

[0058] In a preferred embodiment, the lens assembly 30 and the mainboard assembly 33 utilize a direct plug-in connection, eliminating the need for an adapter plate. Specifically, the lens assembly 30 and the mainboard assembly 33 utilize a mating connection between connector terminals and connector sockets. The cables connecting the connector terminals and connector sockets can utilize, for example, flat cables or flexible printed circuits, allowing the cables to be bundled without being scattered, thus reducing the complexity of cable connection and layout. The corresponding connector terminals and connector sockets are coaxially arranged along an axial direction parallel to the longitudinal direction.

[0059] As shown in FIG. 3 b , in this embodiment, the lens assembly 30 is welded with a connecting cable 301 , and the mainboard assembly 33 is provided with a mainboard connecting terminal 331 , which is plug-connected to the connecting cable 301 .

[0060] In a preferred example, the lens assembly 30 may include a lens main board, which may be arranged on the outer surface of the first fixed plate 711, that is, located in the gap between the first fixed sheet metal 71 and the second fixed sheet metal 72. The partial hollow design of the second fixed plate 721 can realize a direct plug-in connection between the lens assembly 30 and the main board assembly 33, thereby further eliminating the use of connecting cables.

[0061] Specifically, as shown in Figures 1 and 8 , the second fixing sheet metal 72 is sleeved onto the outside of the first fixing sheet metal 71. Therefore, the dimensions of each portion of the second fixing sheet metal 72 should be slightly larger than the corresponding portions of the first fixing sheet metal 71. For example, the length of the second fixing arm 722 is greater than the length of the first fixing arm 712, and the length of the second side is greater than or equal to the length of the first side.

[0062] The rectangular parallelepiped structure formed by the pair of first fixing arms 712 , the pair of second fixing arms 722 , and the first fixing plate 711 can further provide protection for the lens assembly 30 .

[0063] Typically, the fill light assembly is mostly set above the lens assembly, and due to the size of the fuselage, the fill light assembly is adjacent to the lens assembly or the distance between them is very small. Therefore, when the fill light assembly is turned on, the flying insects attracted by it can easily enter the field of view of the lens assembly. Spiders attracted by the flying insects will also often appear in the field of view of the lens assembly due to their biological characteristics and the influence of gravity, and even weave webs in front of the window of the lens assembly, thereby seriously affecting the shooting effect and image quality of the lens assembly.

[0064] In this embodiment, as shown in Figures 2a and 2b , a body shape is provided in which the width is greater than the height, thereby allowing the lens assembly 30 and the fill light assembly 40 to be placed side by side in the horizontal direction. In this embodiment, the length direction of the body 10 is defined as being consistent with the optical axis direction L of the lens assembly 30, wherein the side photographed by the lens assembly 30 is defined as the front side of the optical axis direction L. The body 10 has a cavity inside and an opening 11 on the front side, wherein the shape of the opening 11 is the same as the cross-sectional shape of the body 10. Optionally, the size of the opening 11 may be different from or the same as the cross-sectional size of the body 10. The width direction of the opening 11 extends horizontally, and the height direction extends vertically. The optical axis direction L also extends within the horizontal plane.

[0065] In this embodiment, the width of the opening 11 can be significantly greater than its height, for example, twice its height, so that the lens assembly 30 and the fill light assembly 40 can be placed side by side in the horizontal direction. This eliminates the possibility that flying insects and spiders attracted by the fill light assembly will enter the field of view of the lens assembly 30 due to the influence of gravity.

[0066] As shown in FIG1 and FIG3a , the front cover 20 has a window 31 protruding from the front surface of the front cover 20 , that is, the front cover 20 has a window 31 protruding forward, and the lens assembly 30 shoots through the window 31 . The window 31 is formed in a rectangular shape, and a pair of second through holes 311 are formed at the lower edge of the window 31 , as shown in FIG9 ;

[0067] As shown in FIG4b, FIG9 and FIG10, the camera for reducing interference from flying insects includes a light shield 50. The light shield 50 is installed on the front cover 20 from the outside and surrounds the viewing window 31. The light shield 50 is connected to the front cover 20 and the body 10 by a snap-fit ​​structure, wherein the snap-fit ​​structure includes:

[0068] A pair of first engaging portions 811 , the pair of first engaging portions 811 protruding from the upper edge of the viewing window 31 along the length direction of the front cover 20 ;

[0069] A pair of second engaging portions 812 , the pair of second engaging portions 812 extending from the lower edge of the opening 11 along the length direction to protrude from the front cover 20 through the second through hole 311 ;

[0070] A pair of first locking portions 813 , the pair of first locking portions 813 being mounted on the inner wall of the light shield 50 to engage with the pair of first engaging portions 811 ;

[0071] A pair of second slots 814 penetrates the lower edge of the light shield 50 , and the pair of second engaging portions 812 engage with the pair of second slots 814 .

[0072] In this embodiment, the front cover 20 is securely fastened to the body 10 via the first fastener 21, while the light shield 50 is only secured to the front cover 20. Therefore, by inserting the second engaging portion 812 provided on the body 10 through the second through-hole 311, the second engaging portion 812 can engage with the second engaging slot 814 of the light shield 50, thereby securing the light shield 50 to the body 10 and further improving the securing effect of the light shield 50. As can be seen, the light shield 50 is directly connected to the front cover 20 by engaging the first engaging portion 811 provided thereon, while the light shield 50 is indirectly connected to the body 10 through the front cover 20 by engaging the second engaging slot 814 provided thereon with the second engaging portion 812. To enhance the mosquito repellent effect, in one preferred embodiment, the surface of the light shield 50 is coated with Teflon.

[0073] Teflon generally refers to polytetrafluoroethylene (PTFE), commonly known as the "King of Plastics." It is a high-molecular-weight polymer made from tetrafluoroethylene as a monomer. It exhibits excellent heat and cold resistance, and can be used for extended periods at temperatures between -180°C and 260°C. This material is resistant to acids, alkalis, and various organic solvents, and is virtually insoluble in all solvents. PTFE also boasts high-temperature resistance and an extremely low coefficient of friction, making it an ideal coating for easy-to-clean water pipe linings, in addition to its lubricating properties.

[0074] By utilizing the low friction coefficient characteristic of Teflon, the surface of the light shield 50 is not conducive to the stay of flying insects or spiders. Combined with the structural characteristics of the light shield 50 and the positional relationship between the fill light assembly and the lens assembly, the camera for reducing interference from flying insects in this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the picture shooting quality of the camera.

[0075] Due to the characteristics of the Teflon coating, both the light shield 50 and the front cover 20 are made of metal. Metal materials have high rigidity and are not easily adaptable to snap-fit ​​connection structures. Therefore, in the fixing structure for the light shield 50 in this embodiment, a snap-fit ​​structure consisting of a plastic structure and a metal structure is used to achieve the connection. For example, the first snap-fit ​​portion 811 can be a metal snap-fit ​​portion, the second snap-fit ​​portion 812 can be a plastic snap-fit ​​portion, the first snap-fit ​​portion 813 can be a plastic snap, and the second snap-fit ​​slot 814 can be a metal snap-fit ​​slot.

[0076] Specifically, the hood 50 and front cover 20 are both made of metal, while the body 10 is formed of a plastic material with elastic deformation. Therefore, in this embodiment, the first engaging portion 811 is integrally formed with the front cover 20 and is formed of a metal material, while the second engaging portion 812 is integrally formed with the body 10 and is formed of a plastic material. The first snap portion 813 is formed as a plastic member fixedly connected to the inner wall of the hood 50 via a second fastener, while the second engaging slot 814 is directly defined at the lower edge of the hood 50 and is formed of a metal material.

[0077] In the snap-fit ​​structure of the sunshade 50, in the snap-fitting first snap-fitting portion 811 and the first snap-fitting portion 813, the first snap-fitting portion 811 is made of metal, while the first snap-fitting portion 813 is made of plastic; in the snap-fitting second snap-fitting portion 812 and the second snap-fitting slot 814, the second snap-fitting portion 812 is made of plastic, while the second snap-fitting slot 814 is made of metal.

[0078] The second slot 814 can also be used as a drainage hole.

[0079] Furthermore, as shown in FIG1 and FIG4a and FIG4b, the camera for reducing interference from flying insects of this embodiment further includes:

[0080] The light shield 50 is installed on the front cover 20 from the outside and surrounds the window 31. The light shield 50 includes:

[0081] A top wall 51 , the top wall 51 protrudes from the viewing window 31 from above the viewing window 31 ;

[0082] A first side wall 52 and a second side wall 53 , the first side wall 52 and the second side wall 53 respectively protrude from the window 31 from both sides in the width direction of the window 31 , wherein the first side wall 52 is isolated between the window 31 and the light exit surface 43 ;

[0083] Circular chamfers are formed between the top wall 51 and the first side wall 52 and the second side wall 53 , and circular chamfers are formed between the top wall 51 , the first side wall 52 , the second side wall 53 and the edge of the window 31 .

[0084] In order to further prevent flying insects or spiders from staying near the lens assembly 30, the surface of the lens hood 50 is formed into a smooth surface, and arc chamfers are used between each surface to avoid forming sharp corners or steps, thereby preventing flying insects or spiders from staying on the surface of the lens hood 50.

[0085] In a preferred embodiment, as shown in FIG3a , along the optical axis L, i.e., the Y-axis, the viewing window 31 of the lens assembly 30 is located in front of the light-emitting surface 43 of the fill light assembly 40. Flying insects attracted by the fill light assembly 40 are concentrated near the light-emitting surface 43. Furthermore, due to the limited field of view of the lens assembly 30, the possibility of flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 is minimized. Furthermore, the light source is located behind the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which does not attract flying insects. Consequently, the number of flying insects in front of the lens assembly 30 is significantly reduced.

[0086] As shown in FIG4 a , in the optical axis direction L, the length of the top end of the first side wall 52 and the length of the bottom end of the second side wall 53 are greater than the length of the bottom end;

[0087] The front end of the top wall 51 , the front end of the first side wall 52 , and the front end of the second side wall 53 together form a downwardly inclined light shielding surface that forms an acute angle with the vertical direction.

[0088] As shown in FIG. 5 , in order to prevent the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 , the light emission angle of the fill light assembly 40 avoids the first side wall 52 .

[0089] The field of view of the lens module and the fill light module are the same. When the fill light module is located behind the lens module, ensure that the fill light module's field of view does not interfere with the decorative parts in front of the lens module. The fill light setback distance depends on the lens field of view. The greater the difference between the lens and fill light, the better the effect.

[0090] As shown in FIG1 and FIG12 , the fill light assembly 40 includes a light board main board 41 and a plurality of fill lights 42 a mounted on the light board 42 , and a light emitting surface 43 protruding from the front cover 20 ;

[0091] The light-emitting surface 43 forms a second accommodating cavity on the inner surface of the front cover 20, and the lamp board 42 is installed in the second accommodating cavity; as can be seen from Figures 1, 2a, and 2b, the light-emitting surface 43 is the surface on the front cover 20 that can transmit light, and the second accommodating cavity is the accommodating space formed by the front cover corresponding to the fill light assembly 40, so as to accommodate the lamp board 42.

[0092] The light board main board 41 is installed on the inner surface of the front cover 20 to cover the second accommodating cavity. The light board 42 is fixed to the light board main board 41 via a third fastener. The light board 42 is arranged parallel to the light board main board 41.

[0093] The light board main board 41 includes a light board cable 44 connected between the light board main board 41 and the main board assembly 33, and a light shielding terminal 45 sleeved on the light board cable 44;

[0094] The connection between the light board cable 44 and the light board main board 41 is adjacent to a side edge of the light board main board 41 . A wire outlet gap for the light board cable 44 is formed between the side edge and the inner surface of the front cover 20 , and the light shielding terminal 45 fills the wire outlet gap.

[0095] As shown in FIG14 , the light shielding terminal 45 includes:

[0096] The light shielding body 451 is formed in a rectangular parallelepiped shape, as shown in FIG13 , with two ends of the light shielding body respectively abutting against the light board main board 41 and the front cover 20 ;

[0097] The outlet terminal 452 is formed on the light shield 451 and has an outlet hole that passes through the light shield 451. The light panel cable 44 is installed in the outlet hole. The outlet terminal 452 has an input end 4521 and an output end 4522 located on both sides of the light shield 451. The outlet terminal 452 is formed in a shape that gradually shrinks from the input end 4521 to the output end 4522.

[0098] The wire outlet end 4522 is located at a side away from the second accommodating cavity, and the wire outlet end 4522 wraps the light board cable 44 .

[0099] In this embodiment, the light-emitting surface 43 protrudes from the front cover 20, forming a second accommodating cavity on one side of the inner surface of the front cover 20 for accommodating the light board 42 and the fill light 42a. When the light board main board 41 is installed on the front cover 20, the light board main board 41 is flush with the inner surface of the front cover 20, and the light board 42 and the fill light 42a are accommodated in the second accommodating cavity. The provision of the second accommodating cavity can effectively reduce the exposure of the fill light 42a to the interior of the device body 10. However, the light board cable 44 connected to the light board main board 41 inevitably needs to pass through the side of the light board main board 41 facing the second accommodating cavity and exit the second accommodating cavity. In this embodiment, a light-shielding terminal 45 is provided to shield this cable outlet gap.

[0100] The light-shielding terminal 45, a rectangular parallelepiped light-shielding body 451, is placed within the cable gap between the main light panel 41 and the front cover 20. One end of the light-shielding terminal abuts the main light panel 41, while the other side abuts the light panel 42. The light-shielding terminal 45 is fitted over and wraps around the light panel cable 44 via an outlet terminal 452 with an outlet hole. The outlet terminal 452 is shaped like a flared mouth, gradually narrowing from the inlet end 4521 to the outlet end 4522. The larger inlet end 4521 wraps around the connecting terminal of the light panel cable 44, while the smaller outlet end 4522 wraps around the outlet cable of the light panel cable 44. The outlet end 4522 can be formed as an elastomer to further reduce the possibility of light leakage. As shown in Figure 14, the light shielding body 451 and the outlet terminal 452 are integrally formed. Optionally, the light shielding terminal 45 can be a silicone light shielding member, which is used to block the gap between the front cover 20 and the main light board 41. The larger end of the silicone light shielding member is positioned toward the interior of the fill light assembly 40, while the smaller end of the silicone light shielding member serves as the outlet hole, i.e., the outlet terminal 452, for the lead wires to pass through. Due to the high elasticity of silicone, the lead wires fit tightly into the outlet hole, thereby preventing light leakage from the outlet hole. The silicone light shielding member itself is made of opaque silicone material, thus preventing light leakage from the gap between the front cover 20 and the fill light assembly 40. The multiple fill lights 42a are arranged in a matrix, forming a rectangular shape with a width greater than height.

[0101] In a preferred example, the supplementary light 42a is an insect repellent light.

[0102] Insect repellent lamps, also known as insect-proof lamps, anti-ultraviolet fluorescent lamps, and yellow light lamps, emit yellow light above 450nm, which does not stimulate insect flight or utilizes the light adaptation of its eyes to prevent insects from gathering in illuminated areas or inhibit their nocturnal activities.

[0103] Among them, the light board 42 has three light board fixing studs 421 extending toward the light board main board 41, one pair of the light board fixing studs 421 is formed as positioning studs for the light board main board 41, and another light board fixing stud 421 is formed as a connecting stud for the light board main board 41, and a pair of light board fixing studs 421 are respectively adjacent to a pair of opposite edges of the light board main board 41.

[0104] The lamp board main board 41 has a pair of positioning screw holes 41 a for the positioning studs to pass through, and a connecting screw hole 41 b for connecting the studs to the third fastener.

[0105] The third fastener connected to the positioning screw hole 41 a should include a gasket to prevent light from leaking from the positioning screw hole 41 a.

[0106] Furthermore, the four end corners of the light board main board 41 are fixedly connected to the inner surface of the front cover 20 by fourth fasteners;

[0107] The inner surface of the front cover 20 includes a pair of lamp board mainboard positioning posts 22 protruding toward the lamp board mainboard 41 . The lamp board mainboard positioning posts 22 are respectively adjacent to a pair of non-adjacent end corners of the lamp board mainboard 41 .

[0108] As shown in Figure 3a, in the width direction of the opening 11, an installation gap is formed between the window 31 and the light-emitting surface 43. The installation gap is formed on the front surface of the front cover 20. Therefore, the installation gap is located on the rear side of the window 31 in the optical axis direction L, that is, along the direction parallel to the optical axis, that is, the Y-axis direction, the window 31 is located in front of the light-emitting surface 43.

[0109] As shown in FIG6a and FIG6b, the camera for reducing flying insect interference in this embodiment further includes:

[0110] The decorative cover 60 is installed on the front cover 20 from the outside and surrounds the light-emitting surface 43. The decorative cover 60 has a first edge 61 connected to the first side wall 52. The first edge 61 and the first side wall 52 form a smooth surface that shields the installation spacer.

[0111] 3a and 6b, it can be seen that a mounting gap is formed between the window 31 and the light emitting surface 43, and the decorative cover 60 and the light shield 50 are seamlessly connected, so that there are no protrusions or grooves on the appearance of the camera, thereby reducing spiders from using edges to build webs.

[0112] The front cover 20 has four third slots 23 that pass through the front cover 20 , and the third slots 23 correspond to the end angle positions of the light emitting surface 43 ;

[0113] The inner surface of the decorative cover 60 has a third engaging portion 62 engaged with the third engaging groove 23 . The decorative cover 60 is formed of a plastic material with elastic deformation capacity. The third engaging portion 62 is integrally formed with the decorative cover 60 .

[0114] The decorative cover 60 can be positioned on the front cover 20 by positioning posts 63 protruding from the inner surface thereof, wherein positions of the positioning posts 63 correspond to a pair of non-adjacent end corner edges of the light emitting surface 43 .

[0115] As shown in FIG7 , the lens assembly 30 includes:

[0116] The window glass 32 covers the window 31 from the inner side of the window 31 , wherein the window glass 32 includes a transparent portion 321 filling the window 31 and a fixing portion 322 extending outward from the periphery of the transparent portion 321 ;

[0117] The front end surface of the transparent portion 321 is flush with the outer surface of the window 31 , and the fixing portion 322 is formed on the rear end surface of the transparent portion 321 to form a step with the transparent portion 321 that fits the inner surface of the front cover 20 .

[0118] The window glass in this embodiment adopts the shape of stepped glass. Combined with the installation of the light shield 50, there is no protrusion or groove on the appearance of the camera, thereby reducing the use of edges by spiders to build webs.

[0119] In this embodiment, the lens assembly 30 and the fill light assembly 40 are placed side by side in the horizontal direction, thereby eliminating the possibility that flying insects and spiders attracted by the fill light assembly enter the field of view of the lens assembly 30 due to the influence of gravity.

[0120] Furthermore, along the optical axis L, the viewing window 31 of the lens assembly 30 is located in front of the light-emitting surface 43 of the fill light assembly 40. Flying insects attracted by the fill light assembly 40 are concentrated near the light-emitting surface 43. Furthermore, due to the limited field of view of the lens assembly 30, the possibility of flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 is minimized. Furthermore, the light source is located behind the lens assembly 30, and there is no light source within a certain range in front of the lens assembly 30, which does not attract flying insects. Consequently, the number of flying insects in front of the lens assembly 30 is significantly reduced.

[0121] As shown in FIG. 1 to FIG. 3 a , an embodiment of the present application provides a camera for reducing interference from flying insects, comprising:

[0122] a body 10, the body 10 forming an internal cavity;

[0123] The front cover 20 is mounted on the body 10 to seal the cavity;

[0124] The lens assembly 30 is located in the cavity and has a window 31 protruding from the front cover 20 for shooting through the window 31;

[0125] A fill light assembly 40 is located in the cavity and has a light emitting surface 43 to provide an auxiliary light source toward the field of view of the lens assembly 30 via the light emitting surface 43;

[0126] The lens assembly 30 and the fill light assembly 40 are arranged horizontally on the front cover 20 , and in the optical axis direction, the window 31 of the lens assembly 30 is located in front of the light emitting surface 43 of the fill light assembly 40 .

[0127] Specifically, as shown in FIG1 , the lens assembly 30 and the fill light assembly 40 are independently and separately arranged in the horizontal direction, and the window 31 and the light emitting surface 43 are independently and separately arranged in the horizontal direction.

[0128] The lens assembly 30 and the fill light assembly 40 are spaced apart to form independent components. Further, on the front cover 20, the window 31 and the light emitting surface 43 are also spaced apart to form an installation gap between the window 31 and the light emitting surface 43.

[0129] In a preferred example, the camera of this embodiment for reducing interference from flying insects includes a light shield 50, which is installed on the front cover 20 from the outside and surrounds the window 31. In the direction of the optical axis, the front end surface of the light shield 50 exceeds the light emitting surface 43.

[0130] The front end surface of the sunshade 50 is formed as a light-shielding surface, wherein, in the direction of the optical axis, the light-shielding surface of the sunshade 50 is located in front of the light-emitting surface 43 of the fill light assembly to prevent the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30.

[0131] In a preferred example, the surface of the light shield 50 has a Teflon coating, and the light shield 50 includes a top wall 51 protruding from the viewing window 31 from above the viewing window 31 .

[0132] When the fill light assembly is turned on, the light hood 50 uses the first side wall 52 and the second side wall 53, especially the first side wall 52, to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0133] As shown in FIG. 1 to FIG. 3 a , an embodiment of the present application provides a camera for reducing interference from flying insects, comprising:

[0134] The body 10 is formed as a rectangular parallelepiped with a cavity therein and has an opening 11 formed at a front end in the longitudinal direction. The opening 11 is formed in a rectangular shape with a width greater than a height, wherein both the longitudinal direction and the width direction of the opening 11 extend in a horizontal plane;

[0135] The front cover 20 is installed on the opening 11 to seal the cavity;

[0136] The lens assembly 30 is mounted on the front cover 20 from the inside so as to be located within the cavity. The optical axis of the lens assembly 30 is aligned with the longitudinal direction and faces the front of the front cover 20. The lens assembly 30 has a window 31 protruding from the front cover 20 for capturing images through the window 31.

[0137] A fill light assembly 40 is mounted on the front cover 20 from the inside so as to be located within the cavity. The light emission direction of the fill light assembly 40 is consistent with the length direction. The fill light assembly 40 has a light emission surface 43 that is flush with the front cover 20 or protrudes from the front cover 20 to provide auxiliary light through the light emission surface 43 toward the field of view of the lens assembly 30;

[0138] The lens assembly 30 and the fill light assembly 40 are arranged horizontally on the front cover 20 , and in the optical axis direction, the window 31 of the lens assembly 30 is located in front of the light emitting surface 43 of the fill light assembly 40 .

[0139] As shown in FIG. 1 , the fill light assembly 40 includes a light board 42 and a plurality of fill lights 42 a mounted on the light board 42 , wherein the plurality of fill lights 42 a are arranged in a matrix and formed into a rectangular shape with a width greater than a height.

[0140] In a preferred embodiment, the fill light 42a is an insect repellent lamp. This lamp, also known as an insect repellent lamp, an anti-UV fluorescent lamp, or a yellow light, emits yellow light above 450nm, which does not stimulate insect flight or utilizes the light adaptation of the insects' eyes to prevent them from congregating in illuminated areas or inhibit their nocturnal activities.

[0141] The functions of the lens hood 50 are divided into two types. One is to prevent excessive light from causing glare within the field of view of the lens assembly under sufficient light conditions, especially using the top wall 51 to block the sunlight from above the lens assembly 30; the other is to use the first side wall 52 and the second side wall 53, especially the first side wall 52, to block the light emitted by the fill light assembly from entering the vicinity of the window 31 of the lens assembly 30 when the fill light assembly is turned on, thereby preventing flying insects attracted by the fill light assembly from flying around the window 31.

[0142] By utilizing the low friction coefficient of Teflon, the surface of the lens hood 50 is not conducive to the residence of flying insects or spiders. Combined with the structural characteristics of the lens hood 50 and the positional relationship between the fill light assembly and the lens assembly, the camera of this embodiment can minimize the appearance of flying insects attracted by the fill light assembly within the field of view of the lens assembly, thereby improving the image shooting quality of the camera.

[0143] A second aspect of this embodiment provides a camera for reducing interference from flying insects, comprising: a body 10, a front cover 20, a lens assembly 30, and a fill light assembly 40. The body 10 defines an internal cavity, and the front cover 20 is mounted on the body 10 to seal the cavity. The lens assembly 30 is located within the cavity and has a window 31 protruding from the front cover 20 for capturing images through the window 31. The fill light assembly 40 is located within the cavity and has a light emitting surface 43 for providing auxiliary light to the field of view of the lens assembly 30 through the light emitting surface 43. The lens assembly 30 and the fill light assembly 40 are arranged horizontally on the front cover 20, and the window 31 of the lens assembly 30 is located in front of the light emitting surface 43 of the fill light assembly 40 in a direction parallel to the optical axis.

[0144] In this embodiment, as shown in Figures 2a and 2b , the lens assembly 30 and the fill light assembly 40 are placed side by side horizontally, eliminating the possibility of flying insects and spiders attracted by the fill light assembly entering the field of view of the lens assembly 30 due to the influence of gravity. Furthermore, the window 31 of the lens assembly 30 is located in front of the light-emitting surface 43 of the fill light assembly 40, parallel to the optical axis. Flying insects attracted by the fill light assembly 40 are concentrated near the light-emitting surface 43. Due to the limited field of view of the lens assembly 30, the possibility of flying insects and spiders attracted by the fill light assembly 40 entering the field of view of the lens assembly 30 is minimized. Furthermore, the light source is located behind the lens assembly 30, leaving a certain range in front of the lens assembly 30 without light sources, thereby preventing insect attraction. Consequently, the number of flying insects in front of the lens assembly 30 is significantly reduced.

[0145] In some embodiments, the lens assembly 30 and the fill light assembly 40 are spaced apart in the horizontal direction, and the window 31 and the light emitting surface 43 are spaced apart in the horizontal direction.

[0146] The lens assembly 30 and the fill light assembly 40 are spaced apart to form independent components. Furthermore, the viewing window 31 and the light exit surface 43 on the front cover 20 are also spaced apart. When flying insects gather near the light exit surface 43, they are less likely to enter the area within the viewing window 31, thereby reducing the possibility of webs forming within the area within the viewing window 31 and improving the quality of images captured by the camera.

[0147] In some embodiments, as shown in Figures 6a, 6b and 11, the camera includes a decorative cover 60 and a light shield 50 connected to the front cover 20. Along the direction parallel to the optical axis, the decorative cover 60 is located at the front end of the light emitting surface 43, and the light shield 50 is located at the front end of the window 31; the decorative cover 60 includes a first light emitting hole 60a, which is coaxially arranged with the light emitting surface 43, and the light emitting area of ​​the first light emitting hole 60a is equal to the surface area of ​​the light emitting surface 43, and the light shield 50 includes a second light emitting hole 50a, and the light emitting area of ​​the second light emitting hole 50a is equal to the light emitting area of ​​the window 31; in the direction parallel to the optical axis, at least the front end surface of the light shield 50 is located in front of the decorative cover 60.

[0148] In this embodiment, the light shield 50 is opaque except for the second light exit hole 50a. Therefore, by disposing the light shield 50 in front of the viewing window 31, light emitted by the fill light assembly can be prevented from entering the vicinity of the viewing window 31 of the lens assembly 30. At least the front end of the light shield 50 is located in front of the decorative cover 60, thereby achieving a better light shielding effect.

[0149] It can be understood that the window 31 and the light-emitting surface 43 are spaced apart, which also makes it convenient to set a light shield 50 around the window 31 and a decorative cover 60 around the light-emitting surface 43, wherein the light shield 50 and the decorative cover 60 can be seamlessly connected to prevent flying insects from weaving webs between the light shield 50 and the decorative cover 60.

[0150] In some embodiments, the light shield 50 includes a first side wall 52 and a second side wall 53 arranged in a horizontal direction, and a top wall 51 and a bottom wall 54 perpendicular to and connected to the first side wall 52 and the second side wall 53. The first side wall 52, the second side wall 53, the top wall 51 and the bottom wall 54 are concave to form a second light output hole 50a.

[0151] In this embodiment, the second light exit hole 50a is recessed relative to the solid part of the light shield 50, so that the solid part of the light shield 50 can isolate the light emitted from the light exit surface 43, reduce the brightness of the light at the position of the second light exit hole 50a, and thus reduce the possibility of flying insects gathering in front of the window 31.

[0152] In some embodiments, the surface of the light shield 50 has a Teflon coating; and along a direction parallel to the optical axis, a size of the top wall 51 exceeds a size of the bottom wall 54 .

[0153] Teflon material has the advantage of a low coefficient of friction. The Teflon coating on the surface of the hood 50 leverages this low coefficient of friction, making the surface of the hood 50 less conducive to insects and spiders, thereby reducing the likelihood of insects forming webs in front of the viewing window 31. Furthermore, the top wall of the hood 50 protrudes further forward than the bottom wall. In sufficient light, the top wall 51 shields sunlight from above the lens assembly 30, preventing glare within the field of view of the lens assembly 30 caused by excessively strong light.

[0154] The series of detailed descriptions listed above are merely specific descriptions of feasible implementation methods of the present application, and are not intended to limit the scope of protection of the present application. Any equivalent implementation plans or changes that do not depart from the technical spirit of the present application, such as the combination, division or repetition of features, should be included in the scope of protection of the present application.
