Technical Field

[0002] This application relates to the field of photographic and video equipment technology, and in particular to a photographic light assembly and photographic lighting system. Background Technology

[0003] In some outdoor shooting scenarios today, it is often necessary to use photography lights to emit near-parallel light into the distance, so large reflectors or diffusers need to be installed on the photography lights.

[0004] By adding a reflector or diffuser to the end of the camera light, the light emitted by the camera light can be reflected by the reflective surface on the inside of the reflector or diffuser, becoming parallel light, and then emitted to a distance to achieve the lighting effect of parallel light.

[0005] However, as shown in Figure 1, some of the light emitted by the photographic light source will not be reflected by the reflective surface and will be emitted directly from the front surface of the reflector or diffuser. This directly emitted light source will form a diverging light area on the outer periphery of the parallel light area, resulting in poor uniformity in the illuminated surface. This seriously affects the illumination effect of the photographic light source and, consequently, the imaging effect of the photograph, and it cannot well meet the needs of the photograph. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem in the prior art where some of the light emitted by photographic lights is emitted directly from the front surface of the reflector or diffuser without being reflected by the reflective surface. This directly emitted light forms a diverging light area on the outer periphery of the parallel light area, resulting in poor uniformity of the illuminated surface, which seriously affects the illumination effect of the photographic lights and consequently the imaging effect of the photograph, thus failing to meet the needs of shooting.

[0007] To address the aforementioned technical problems, the present invention provides a photographic light assembly for connection to a light source, the photographic light assembly comprising:

[0008] The lampshade is open at both ends and hollow inside. The two openings are a light inlet and a light outlet, parallel to each other and arranged along the same axis. The end face of the light inlet is used to connect to the light source. The inner wall of the lampshade is a reflective surface. In the direction from the light inlet to the light outlet, the reflective surface extends in a gradually expanding parabolic shape. The light emitted by the light source is reflected by the reflective surface to form parallel light perpendicular to the plane of the light outlet. Two points on a parallel projection plane, with a phase difference of 180° between the light inlet and the light outlet, are connected by lines forming a reflective area enclosed by the reflective surface.

[0009] A light-shielding unit is disposed inside the lampshade, and the diameter of the light-shielding unit is smaller than the diameter of the light outlet. The light-shielding unit can block the light emitted by the light source, and the center of the light-shielding unit is coaxially arranged with the center of the light inlet. The light-shielding unit is disposed in the reflection area, and the peripheral edges of the light-shielding unit are tangent to the predetermined intersection line of the reflection area.

[0010] In some embodiments of this application, in the direction from the light inlet to the light outlet, the light-shielding unit is a structure with a gradually increasing cross-section, and the maximum diameter of the light-shielding unit is not greater than the outer diameter of the lampshade body at the end where the light inlet is located.

[0018] In some embodiments of this application, the light-shielding unit is a circular sheet structure.

[0019] In some embodiments of this application, the photographic light assembly further includes a light shield, which is disposed at the light outlet of the lamp cover and can block the light emitted by the light source;

[0020] The light-shielding ring includes an annular ring body and a connecting rod, the connecting rod being disposed on the inner wall of the ring body;

[0021] The photographic light assembly also includes a connecting post connected to the end face of the lamp cover body with a light outlet. The connecting post has a connecting hole, and the plug rod is inserted into the connecting hole, so that the light shield is connected to the light outlet of the lamp cover body.

[0022] This application also provides a photographic lighting system, which includes a light source and the above-mentioned photographic light assembly, wherein the light source is connected to the end face of the lamp cover where the light inlet is provided;

[0023] The light emitted by the light source can enter the interior of the lampshade through the light inlet, and after being reflected by the reflective surface and absorbed by the light-shielding unit, it forms parallel light perpendicular to the plane of the light outlet and is emitted from the light outlet.

[0024] In some embodiments of this application, the lampshade is a diffuser, and a diffuser cloth is provided at the light outlet of the diffuser; the light source is an LED surface light source.

[0025] This application also provides a photographic light assembly, which includes:

[0026] The lampshade has openings at both ends and is hollow inside. The two openings at the ends of the lampshade are a light inlet and a light outlet, respectively. The outer wall of the end of the lampshade with the light inlet is used to connect a light source. The inner surface of the lampshade is a reflective surface. The light emitted by the light source enters the interior of the lampshade through the light inlet and can be reflected by the reflective surface before exiting through the light outlet.

[0027] The lens is transparent and allows light to pass through. The lens is disposed on the end face of the lampshade body with a light outlet and completely covers the light outlet of the lampshade body to form a barrier between the interior of the lampshade body and the external environment.

[0028] In some embodiments of this application, the lampshade body has a plurality of positioning portions on the end face with the light outlet, and the outer edge of the lens has a plurality of positioning notches corresponding one-to-one with the positioning portions.

[0030] In some embodiments of this application, the photographic lamp assembly further includes multiple light-shielding rings, which are disposed on the inner side of the lens facing the lamp cover body and are concentrically arranged. Adjacent light-shielding rings are spaced apart to form an optical path channel through which light passes. The light-shielding rings can block light passing through the optical path channel and not perpendicular to the end face where the light outlet is located from being emitted from the light outlet.

[0031] The photographic light assembly also includes a honeycomb assembly located on the outer side of the lens opposite to the lamp housing, and the honeycomb assembly is detachably connected to the lamp housing.

[0032] The honeycomb assembly has multiple light-transmitting holes arranged in a honeycomb array. The inner sidewall of the light-transmitting holes of the honeycomb assembly is a light-absorbing surface, which is used to block light rays that are not parallel to the axis of the light-transmitting holes.

[0033] In some embodiments of this application, the photographic lamp assembly further includes multiple locking components, each locking component including a limiting post and a limiting cover. The multiple limiting posts are circumferentially spaced around the outer edge of the front end face of the lamp cover, and the limiting cover is rotatably connected to the limiting post and can rotate about the axis of the limiting post.

[0034] When the limiting cover rotates to the front end face of the honeycomb assembly and abuts against the front end face of the honeycomb assembly, the limiting cover presses the honeycomb assembly against the front end face of the lampshade body, and the honeycomb assembly is locked to the lampshade body; when the limiting cover rotates and leaves the front end face of the honeycomb assembly, the limiting cover releases the lock on the honeycomb assembly.

[0035] The locking assembly further includes a limiting bolt and an elastic element. The limiting bolt passes through the limiting cover and the limiting post and is connected to the front end face of the lampshade body. The elastic element is disposed between the limiting bolt and the limiting cover and is used to press the limiting cover against the limiting post.

[0036] The limiting cover includes a protrusion and a recess that are disposed opposite to each other.

[0037] In some embodiments of this application, the lampshade includes a reflector cup and a housing. The reflector cup has two open ends and is hollow inside to form a reflective cavity. The inner sidewall of the reflector cup is a reflective surface. The housing covers the outer sidewall of the reflector cup, and the housing and the outer sidewall of the reflector cup are spaced apart to form a heat dissipation space. The housing has a hollowed-out portion that connects the heat dissipation space to the external environment.

[0038] This application also provides a photographic lighting system, which includes:

[0039] The light source is an LED light source;

[0040] In the aforementioned photographic light assembly, the outer wall of the end of the photographic light assembly with a light inlet is provided with a connecting arm, which is connected to the LED light source so as to fix the LED light source to the photographic light assembly and to align the light-emitting end of the LED light source with the light inlet of the photographic light assembly.

[0041] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows: In the photographic light assembly and photographic lighting system of the present invention, the photographic light assembly includes a lampshade body and a light-shielding unit. The inner wall of the lampshade body is a reflective surface, which is in the shape of a gradually expanding parabola. The light emitted by the light source is reflected by the reflective surface to form parallel light perpendicular to the plane where the light outlet is located. A reflective area is also formed inside the lampshade body, and the light-shielding unit is disposed in the reflective area. The peripheral edges of the light-shielding unit are tangent to the set intersection line of the reflective area, so that the light-shielding unit can absorb the light emitted by the light source that is not reflected by the reflective surface, thereby effectively reducing the amount of non-parallel light contained in the light emitted from the lampshade body, improving the uniformity of the entire illumination surface, effectively improving the imaging effect of the shot, and efficiently meeting the user's shooting needs.

[0069] Embodiment 1 of the photographic light assembly of this application

[0070] Referring to Figures 2 to 5, an embodiment of this application provides a photographic light assembly 100 for connection to a light source 200. The photographic light assembly 100 includes a lampshade body 10 and a light-shielding unit 20.

[0071] The lampshade body 10 is open at both ends and hollow inside. The two ends of the lampshade body 10 have parallel light inlet 101 and light outlet 102 arranged in the same axial direction. The end face of the lampshade body 10 with light inlet 101 is used to connect the light source 200. The inner wall of the lampshade body 10 is a reflective surface 103. In the direction from the light inlet 101 to the light outlet 102 of the lampshade body 10, the reflective surface 103 extends in a gradually expanding parabolic shape. The light emitted by the light source 200 is reflected by the reflective surface 103 to form parallel light perpendicular to the plane where the light outlet 102 is located.

[0072] The light inlet 101 and the light outlet 102 are two points with a phase difference of 180° on the orthographic projection plane parallel to them. The set of lines connecting the points on the outer diameter edge of the light inlet 101 and the outer diameter edge of the light outlet 102 respectively, together with the reflective surface 103, forms the reflective area 105.

[0073] The light-shielding unit 20 is disposed inside the lampshade, and the diameter of the light-shielding unit 20 is smaller than the diameter of the light outlet 102. The light-shielding unit 20 can block the light emitted by the light source 200, and the center of the light-shielding unit 20 is coaxially arranged with the center of the light inlet 101. In the direction from the light inlet 101 to the light outlet 102, the light-shielding unit 20 has a structure whose cross-section gradually increases.

[0074] The light-shielding unit 20 is disposed in the reflection area 105, and the peripheral edges of the light-shielding unit 20 are all tangent to the set intersection line 104 of the reflection area 105.

[0075] In some embodiments of this application, the photographic light assembly 100 further includes a support base 30. The support base 30 may be C-shaped, and its two ends at the opening are respectively connected to the two sides of the outer wall of the lamp cover body 10.

[0076] In some examples, the lampshade 10 can be rotatably connected to the support 30. The lampshade 10 can rotate relative to the lampshade 30 to adjust the illumination angle of the light source 200.

[0077] In some embodiments of this application, the lampshade body 10 may include a main body 11 and an inlet end face 12 and an outlet end face 13 connected to both ends of the main body 11. The inlet end face 12 is provided with a light inlet 101, and the outlet end face 13 is provided with a light outlet 102. The diameter of the light inlet 101 is smaller than the diameter of the light outlet 102.

[0078] In some examples, the photographic light assembly 100 may also include a connecting arm 40 disposed on the outer wall of the inlet end face 12. One end of the connecting arm 40 is connected to the lamp cover body 10, and the connecting arm 40 can also be used to connect to the light source 200. The connecting arm 40 is disposed on one side of the light inlet 101, and the light source 200 is connected to the connecting arm 40 to be fixed to the lamp cover body 10, so that the light emitted by the light source 200 can enter the interior of the lamp cover body 11 through the light inlet 101.

[0079] The inner wall of the lampshade body 11 is a reflective surface 103. In the direction from the light inlet 101 of the lampshade body 10 to the light outlet 102, the extension trend of the reflective surface 103 is a gradually expanding parabola. The light emitted by the light source 200 is reflected by the reflective surface 103 to form parallel light that is perpendicular to the plane where the light outlet 102 is located.

[0080] In some examples, the cross-section of the lampshade 10 is circular along its axial direction. The area of ​​the cross-section of the lampshade 10 gradually increases from the light inlet 101 to the light outlet 102. That is, in this embodiment, the light inlet 101 of the lampshade 10 is a small opening, and the light outlet 102 of the lampshade 10 is a large opening, with the lampshade 10 gradually widening in the direction from the light inlet 101 toward the light outlet 102.

[0081] In some examples, the ratio between the length of the lampshade body 10 and the diameter of the cross-section at the light outlet 102 is (0.5-0.8):1.

[0082] This configuration allows the light emitted from the light source 200 mounted on the lampshade body 10 to be effectively reflected inside the lampshade body 10. Under the action of the reflective surface 103, the light is effectively reflected, ensuring the light output effect of the light source 200 and improving the light output efficiency of parallel light.

[0083] Referring to Figure 5, in some embodiments of this application, two points at 180° intervals along the edge of the light inlet 101 of the lampshade 10 are designated as inlet setting points, and the line connecting the two inlet setting points is the inlet setting line. Similarly, two points at 180° intervals along the edge of the light outlet 102 are designated as outlet setting points, and the line connecting the two outlet setting points is the outlet setting line. The inlet setting line and the outlet setting line are arranged perpendicularly.

[0084] The edge of the light inlet 101 may include multiple sets of inlet setting points, and the edge of the light outlet 102 may include multiple sets of outlet setting points. Each set of inlet setting points includes two inlet setting points distributed at 180°, and each set of outlet setting points includes two outlet setting points distributed at 180°.

[0085] Two inlet setting points in each set of inlet setting points and two outlet setting points in each set of outlet setting points can form two intersecting setting lines 104. Multiple setting lines 104 formed by multiple sets of inlet setting points and multiple sets of outlet setting points can form a reflection zone 105 by enclosing the reflection surface 103.

[0086] The cross line 104 is defined as two points on the orthographic projection plane parallel to the light inlet 101 and the light outlet 102, with a phase difference of 180°, which are respectively the line connecting the points on the outer diameter edge of the light inlet 101 and the outer diameter edge of the light outlet 102.

[0087] The light-shielding unit 20 can be made of a light-absorbing material, or the surface of the light-shielding unit 20 can be provided with a light-absorbing material. The light-shielding unit 20 is disposed in the reflection area 105, and the peripheral edges of the light-shielding unit 20 are tangent to the designated intersection line 104 of the reflection area 105, so that the light-shielding unit 20 can absorb the light emitted by the light source 200 that is not reflected by the reflection surface 103. That is, the light-shielding unit 20 can absorb the light outside the reflection area 105 to prevent this part of the light from shining directly to the outside through the light outlet 102.

[0088] Referring to Figures 3 and 4, in some embodiments of this application, the light-shielding unit 20 includes a plurality of annular light-shielding members 21, which are concentrically arranged and spaced apart. The peripheral edge of each light-shielding member 21 is tangent to the predetermined intersection line 104 of the reflective area 105. In some examples, the outer contour of the light-shielding member 21 is circular.

[0089] In the diametrical direction of the light-shielding unit 20, multiple light-shielding elements 21 are arranged sequentially from the inside to the outside in order of increasing diameter. In the diametrical direction of the light-shielding unit 20, the length of the multiple light-shielding elements 21 gradually decreases in the order of their arrangement from the inside to the outside. In some examples, the end faces of the multiple light-shielding elements 21 facing the light outlet 102 are flush.

[0090] By configuring the light-shielding unit 20 into a structure in which multiple light-shielding elements 21 are arranged concentrically and at intervals, the parallel light emitted by the light source 200 can be emitted in parallel from the interior of the light-shielding element 21 and the gap between two adjacent light-shielding elements 21, thus preventing this part of the light from being absorbed by the light-shielding unit 20 and ensuring the light output efficiency of the parallel light.

[0091] In some embodiments of this application, the maximum diameter of the light-shielding unit 20 is not greater than the diameter of the end face of the lampshade body 10 with the light inlet 101, that is, the maximum diameter of the light-shielding unit 20 is not greater than the diameter of the inlet end face 12 of the lampshade body 10. In some embodiments of this application, the minimum diameter of the light-shielding unit 20 is not less than the diameter of the light inlet 101.

[0092] In some examples, the length of the light-shielding member 21 can be set to 50mm-100mm, and the spacing between two adjacent light-shielding members 21 can be set to 20mm-50mm.

[0093] In some embodiments of this application, the light-shielding unit 20 may further include a connector 22, which is disposed between two adjacent light-shielding units 21.

[0094] The connector 22 can be made of a light-absorbing material, or the surface of the connector 22 can be coated with a light-absorbing material. Multiple connectors 22 can be provided, and multiple connectors 22 can be arranged in the same diametrical direction of the light-shielding member 21.

[0095] In some examples, the photographic light assembly 100 also includes a bracket 50, one end of which is connected to the light-shielding unit 20, and the other end of which is connected to the inner wall of the inlet end face 12 of the lampshade body 10.

[0096] Multiple brackets 50 can be installed, such as two, three, or five. The number of brackets 50 is not limited here; it can be set according to actual use and design requirements. Multiple brackets 50 can ensure the stability of the light-shielding unit 20 in the lampshade body 10, and ensure that the light-shielding unit 20 effectively blocks and absorbs light.

[0097] Referring to Figures 6 and 7, in some embodiments of this application, the light-shielding unit 20 has a disc-shaped structure.

[0098] The light-shielding unit 20 can be made of a light-absorbing material, or the surface of the light-shielding unit 20 can be provided with a light-absorbing material. The light-shielding unit 20 is disposed in the reflection area 105, and the peripheral edges of the light-shielding unit 20 are tangent to the designated intersection line 104 of the reflection area 105, so that the light-shielding unit 20 can absorb the light emitted by the light source 200 that is not reflected by the reflection surface 103. That is, the light-shielding unit 20 can absorb the light outside the reflection area 105 to prevent this part of the light from shining directly to the outside through the light outlet 102.

[0099] As shown in Figures 8 and 9, in some embodiments of this application, the light-shielding unit 20 is a circular sheet structure. In this example, the light-shielding unit 20 is relatively thin and is generally sheet-like.

[0100] The light-shielding unit 20 may be made of light-absorbing material, or the surface of the light-shielding unit 20 may be provided with light-absorbing material. The light-shielding unit 20 may be connected to the inner wall of the inlet end face 12 of the lampshade body 10 via a bracket 50.

[0101] A light-shielding unit 20 is disposed in the reflective area 105. The peripheral edges of the light-shielding unit 20 are tangent to the designated intersection line 104 of the reflective area 105, so that the light-shielding unit 20 can absorb light emitted from the light source 200 that is not reflected by the reflective surface 103. That is, the light-shielding unit 20 can absorb light outside the reflective area 105 to prevent this part of the light from shining directly to the outside through the light outlet 102.

[0102] In addition, in some other examples, the light-shielding unit 20 can also be configured as a cone shape. The small end of the light-shielding unit 20 is positioned towards the light inlet 101 of the lampshade body 10, and the large end of the light-shielding unit 20 is positioned towards the light outlet of the lampshade body 10.

[0103] Referring to Figures 10 to 12, in some embodiments of this application, the photographic lamp assembly 100 further includes a light-shielding ring 60, which is disposed at the light outlet 102 of the lamp cover body 10.

[0104] The light-shielding ring 60 can be made of light-shielding material, or the surface of the light-shielding ring 60 can be provided with light-absorbing material, so that the light-shielding ring 60 can absorb the light emitted by the light source 200, so as to effectively ensure that the light emitted from the light outlet 102 is parallel light.

[0105] In some examples, the light-shielding ring 60 may include an annular ring body 61 and a connecting rod 62 disposed on the inner wall of the ring body 61.

[0106] The photographic light assembly 100 also includes a connecting post 70 connected to the outlet end face 13 of the lamp cover body 10. The connecting post 70 has a connecting hole 71, and the plug rod 62 is inserted into the connecting hole 71, so that the light shield 60 is connected to the light outlet 102 of the lamp cover body 10.

[0107] Example 1 of the photographic lighting system in this application

[0108] Furthermore, as shown in Figure 13, this application also provides a photographic lighting system 1000, which includes a light source 200 and the aforementioned photographic light assembly 100. The structure of the photographic light assembly 100 has been described above and will not be repeated here.

[0109] The light source 200 can be an LED surface light source. The light source 200 can be fixed to the outer wall of the inlet end face 12 of the lampshade body 10 via the connecting arm 40. The light emitted by the light source 200 can enter the interior of the lampshade body 10 through the light inlet 101, and after being reflected by the reflective surface 103 and absorbed by the light-shielding unit 20, it forms parallel light perpendicular to the plane of the light outlet 102 and is emitted from the light outlet 102.

[0110] Referring to Figures 14 and 15, in some examples, the lampshade 10 can also be a diffuser, with a diffuser cloth 80 provided at the light outlet 102 of the diffuser. The diffuser cloth 80 can soften the light, making the parallel light softer and improving the light effect.

[0111] For the photographic light assembly 100 and photographic lighting system 1000 of this application, the photographic light assembly 100 includes a lampshade body 10 and a light-shielding unit 20. The inner wall of the lampshade body 10 is a reflective surface 103, which is in the shape of a gradually expanding parabola. The light emitted by the light source 200 is reflected by the reflective surface 103 to form parallel light perpendicular to the plane where the light outlet 102 is located. A reflective area 105 is also formed inside the lampshade body 10. The light-shielding unit 20 is disposed in the reflective area 105. The peripheral edges of the light-shielding unit 20 are tangent to the set intersection lines of the reflective area 105, so that the light-shielding unit 20 can absorb the light emitted by the light source 200 that is not reflected by the reflective surface 103, thereby effectively reducing the amount of non-parallel light contained in the light emitted from the lampshade body 10, improving the uniformity of the entire illumination surface, effectively improving the imaging effect of the shot, and efficiently meeting the user's shooting needs.

[0112] Example 2 of the photographic lighting system in this application

[0113] Please refer to Figures 16 to 18. This application also provides a photographic lighting system 1000, which includes a light source 200 and a photographic light assembly 100.

[0114] The light source 200 can be an LED light source, which includes a housing and a light-emitting end. The housing has connection holes on both sides, which can be connected to the photography light assembly 100 through the connecting arm 40 to fix the light source 200 on the photography light assembly 100.

[0115] In some examples of this embodiment, one end of the housing of the light source 200 is provided with a bayonet, which can be engaged with the snap-fit ​​member 1122 provided on the photographic lamp assembly 100. The bayonet on the light source 200 is provided with a light outlet, so that the light emitted by the light-emitting end inside the housing can be emitted through its light outlet and enter the interior of the photographic lamp assembly 100.

[0116] In some other embodiments, the light-emitting end of the light source 200 can be a cylindrical LED tube, which can extend from the bayonet on the light source 200 to the outside of the housing. When the bayonet on the light source 200 engages with the snap-fit ​​member 1122 of the photographic light assembly 100, the LED tube on the light source 200 can extend into the interior of the photographic light assembly 100 so that all the light energy emitted by the LED tube is reflected by the photographic light assembly 100, thereby improving the light utilization rate.

[0117] Embodiment 2 of the photographic light assembly of this application

[0118] Referring to Figures 17 to 20, one embodiment of this application also provides a photographic light assembly 100, which includes a lampshade body 10 and a lens 91. The lampshade body 10 is open at both ends and hollow inside, with the two ends being a light inlet 101 and a light outlet 102, respectively. The outer wall of the end of the lampshade body 10 with the light inlet 101 is used to connect a light source 200, and the inner surface of the lampshade body 10 is a reflective surface. Light emitted from the light source 200 enters the interior of the lampshade body 10 through the light inlet 101 and is reflected by the reflective surface before exiting from the light outlet 102.

[0119] The lens 91 is transparent and allows light to pass through. The lens 91 is positioned on the end face of the lampshade 10 where the light outlet 102 is located, and covers the light outlet 102 of the lampshade 10, thus creating a barrier between the interior of the lampshade 10 and the external environment. This prevents dust and insects from entering the interior of the reflector cup 112, effectively ensuring the smoothness of the reflective surface inside the lampshade 10, thereby guaranteeing the reflective efficiency and illumination effect of the photographic light assembly 100.

[0120] In some examples of this embodiment, the lens 91 can be made of transparent glass, transparent plastic, transparent resin, or other materials, as long as it allows light to pass through smoothly and blocks the light outlet 102 of the photographic light assembly 100, preventing external dust, insects, etc. from entering the interior of the lampshade 10.

[0121] In some examples of this embodiment, the shape and size of the lens 91 can be reasonably configured according to the size and shape of the light outlet 102 of the lampshade body 10.

[0122] In this embodiment, the edge of the lens 91 is provided with multiple through holes, and the end face of the light outlet 102 of the lampshade body 10 is provided with multiple screw holes corresponding to the through holes. The screw passes through the through holes on the lens 91 and connects with the screw holes so that the lens 91 can be fixed to one end of the light outlet 102 of the lampshade body 10.

[0123] The lens 91 and the lampshade 10 are connected by screws, which facilitates the replacement of the lens 91. When the surface of the lens 91 becomes blurred and its light transmittance decreases due to external dust or insect impact, the lens 91 can be replaced by unscrewing the screws.

[0124] Of course, in some other embodiments, the lens 91 can also be fixed to the lampshade body 10 by interference fit, Velcro connection, or adhesive bonding.

[0125] Please refer to Figures 21 and 22. In this embodiment, the end face of the light outlet 102 of the lampshade body 10 is also provided with multiple protruding positioning portions 1112. The lens 91 is provided with multiple positioning notches that match the positioning portions 1112. The positioning portions 1112 can be accommodated in the positioning notches of the lens 91 to realize the connection and positioning of the lens 91.

[0126] When installing the lens 91, first align the positioning notch of the lens 91 with the positioning part 1112 on the front end face of the lampshade body 10, so that the positioning notch of the lens 91 is locked with the positioning part 1112, thus freeing the installer's hands. At this time, the through hole on the lens 91 corresponds exactly to the screw hole on the lampshade body 10. After passing the screw through the through hole on the lens 91, screw it into the screw hole on the lampshade body 10 to fix the lens 91 to the lampshade body 10.

[0127] In some examples of this embodiment, the positioning part 1112 may include a support post and a positioning ring disposed on the support post. The outer edge of the positioning ring may abut against the inner edge of the positioning notch of the lens 91 to achieve positioning of the lens 91.

[0128] Referring to Figures 19 and 20, in this embodiment, the lampshade body 10 includes a reflector cup 112 and a housing 111. The reflector cup 112 has open ends and a hollow interior forming a reflective cavity, and the inner sidewall of the reflector cup 112 is a reflective surface. The housing 111 covers the outer sidewall of the reflector cup 112, and the housing 111 and the outer sidewall of the reflector cup 112 are spaced apart to form a heat dissipation space.

[0129] The spaced distance between the housing 111 and the reflector 112 prevents operators from directly contacting the reflector 112 and causing burns, effectively improving the safety of the photographic light assembly 100.

[0130] Please refer to Figure 20. In this embodiment, the outer shell 111 is provided with a hollow part 1111. The hollow part 1111 connects the heat dissipation space with the external environment, so that the heat on the reflector cup 112 can be quickly dissipated through the hollow part 1111 on the outer shell 111, preventing the reflector cup 112 from being damaged due to excessive temperature. This can effectively improve the product life of the photographic light assembly 100.

[0131] Please refer to Figure 20. In this embodiment, the reflector cup 112 includes a cup body 1123 and a connecting base plate 1120 disposed at the rear end of the cup body 1123.

[0132] The cup body 1123 has open ends and a hollow interior to form a bowl-shaped reflective cavity. The sidewalls of the reflective cavity of the cup body 1123 are reflective surfaces used to concentrate light so that the light can be emitted from the light outlet 102. The rear end face of the cup body 1123 of the reflector cup 112 is fixed to the connecting base plate 1120 by bolts to facilitate the disassembly of the cup body 1123. One end of the housing 111 of the photographic light assembly 100 is connected to the outer edge of the connecting base plate 1120, and the other end is connected to the outer edge of the light outlet 102 of the cup body 1123 of the reflector cup 112, so that the housing 111 can cover the outer side of the cup body 1123 of the reflector cup 112.

[0133] In this embodiment, the snap-fit ​​member 1122 on the connecting base plate 1120 is snapped into the snap-fit ​​member on the light source 200, thereby fixing the light source 200 on the connecting base plate 1120. The snap-fit ​​member 1122 is provided with a light inlet 101, which is connected to the reflective cavity inside the reflector cup 112, so that the light emitted from the light outlet of the light source 200 can enter the interior of the reflector cup 112 through the light inlet 101, be focused by the reflective surface of the reflector cup 112, and then be emitted from the lens 91 at the light outlet 102.

[0134] In some embodiments, the light source 200 can be an LED surface light source with a planar light-emitting end. The LED surface light source can be disposed in the light inlet 101, so that the light emitted by the LED surface light source enters the interior of the reflector cup 112 through the light inlet 101, is focused by the reflective surface of the reflector cup 112, and is then emitted from the lens 91 at the light outlet 102.

[0135] Please refer to Figures 10 and 20. In this embodiment, the outer wall of the end of the lampshade body 10 with the light inlet 101 is provided with two connecting arms 40. The connecting arms 40 are provided on both sides of the light inlet 101 and are used to connect and fix with the light source 200.

[0136] Specifically, the lampshade body 10 has two connecting seats 1121 on its connecting base plate 1120. The connecting seats 1121 are connected to one end of the connecting arm 40 by bolts, so that the connecting arm 40 is fixed on the connecting seat 1121. The other end of the connecting arm 40 extends in a direction perpendicular to the connecting base plate 1120 and is fixed to the connecting holes on the two sides of the light source 200 by screws, so as to fix the light source 200 and the photographic lamp assembly 100 and prevent them from detaching from each other.

[0137] Referring to Figure 20, in this embodiment, the photographic light assembly 100 further includes a light-shielding member 21. Multiple light-shielding members 21 are provided, and these members are disposed on the inner side of the lens 91 facing the lampshade body 10.

[0138] Multiple light-shielding elements 21 are arranged concentrically, with adjacent light-shielding elements 21 spaced apart to form a light path channel through which light passes. The light-shielding elements 21 can absorb light passing through the light path channel that is not perpendicular to the end face of the light outlet 102.

[0139] Specifically, the light-shielding member 21 is in the shape of a ring, and multiple light-shielding members 21 are arranged at radial intervals along the lens 91. They are fixed to the edge of the outer shell 111 by fixing rods 211 that are inserted horizontally and vertically inside the light-shielding member 21, so that the light-shielding member 21 can be fixed to the inner side of the lens 91.

[0140] In this embodiment, the light-shielding member 21 is made of black light-absorbing material. When light is reflected by the reflective surface of the reflector cup 112 and then passes through the light path channel formed between two adjacent light-shielding members 21, the light-shielding member 21 can absorb and block light that is not perpendicular to the end face of the light outlet 102, and filter the light passing through the light-shielding member 21 into parallel light.

[0141] Referring to Figures 19, 21, and 22, in this embodiment, the photographic lamp assembly 100 further includes a honeycomb assembly 92. The honeycomb assembly 92 is detachably connected to one side of the light outlet 102 of the lamp housing 10 and is located on the outer side of the lens 91 opposite to the lamp housing 10. The honeycomb assembly 92 has a plurality of light-transmitting holes 921 arranged in a honeycomb array. The sidewalls of the light-transmitting holes 921 of the honeycomb assembly 92 are light-absorbing surfaces, which are used to absorb light rays that are not parallel to the axis of the light-transmitting holes 921.

[0142] Specifically, in this embodiment, the honeycomb assembly 92 has the same function as the light shield 21. It is located on the outer side of the lens 91, allowing light passing through the lens 91 to pass through the light-transmitting hole 921. The inner side of the light-transmitting hole 921 is made of black light-absorbing material, which can absorb light that is not parallel to the axis of the light-transmitting hole 921, making the light passing through the light-transmitting hole 921 parallel light, thereby further improving the levelness of the light emitted by the photographic light assembly 100.

[0143] Please refer to Figures 21 to 23. In this embodiment, the camera light assembly 100 also includes a plurality of locking components 93. The locking components 93 are used to lock and unlock the honeycomb assembly 92, so that the honeycomb assembly 92 can be easily and quickly disassembled from the lamp cover body 10.

[0144] The locking assembly 93 includes a limiting post 931 and a limiting cover 932. Multiple limiting posts 931 are circumferentially spaced around the outer edge of the front end face of the lampshade body 10, and the limiting cover 932 is rotatably connected to the limiting post 931 and can rotate along the axial direction of the limiting post 931.

[0145] When the limiting cover 932 rotates to the front end face of the honeycomb assembly 92 and abuts against the front end face of the honeycomb assembly 92, it presses and fixes the honeycomb assembly 92 onto the front end face of the lampshade body 10, thereby locking the honeycomb assembly 92 and the lampshade body 10 together. When the limiting cover 932 rotates and moves away from the front end face of the honeycomb assembly 92, the locking of the honeycomb assembly 92 is released.

[0146] Furthermore, the limiting cover 932 includes a protrusion and a recess that are disposed opposite to each other. The distance between the protrusion and the pivot of the limiting cover 932 is greater than the distance between the recess and the pivot of the limiting cover 932, so that the limiting cover 932 forms an eccentric rotation structure.

[0147] Specifically, in this embodiment, the protrusion of the limiting cover 932 is an arc surface, and the recess is a plane. The distance from the arc surface to the pivot is greater than the distance from the plane to the pivot, so that when the limiting cover 932 rotates 180° around the axis of the limiting post 931, the directions of the protrusion and the recess can be interchanged to lock and unlock the honeycomb assembly 92.

[0148] In some other embodiments, the limiting cover 932 can also be configured as a pointer, as long as it can achieve eccentric rotation at both ends, so that the limiting cover 932 can abut against the honeycomb component 92 after rotating at a certain angle, or unlock by leaving the front end of the honeycomb component 92.

[0149] Referring to Figure 23, in this embodiment, the locking assembly 93 further includes a limiting bolt 933 and an elastic element 934. The limiting bolt 933 passes through the limiting cover 932 and the limiting post 931 and is connected to the front end face of the lampshade body 10. The elastic element 934 is disposed between the limiting bolt 933 and the limiting cover 932, and is used to press the limiting cover 932 against the limiting post 931.

[0150] Specifically, in this embodiment, the elastic element 934 is a spring, which is used to provide clamping force to ensure that the limiting cover 932 is always pressed against the limiting post 931 without the action of external force, so as to maintain the locking and fixing of the honeycomb assembly 92.

[0151] Furthermore, a spring is provided between the end of the limiting bolt 933 and the limiting cover 932, which allows the limiting cover 932 to move back and forth a short distance along the axial direction of the limiting bolt 933, so that the limiting cover 932 can better pass over the front end face of the honeycomb assembly 92 when it rotates, thereby achieving locking or unlocking with the honeycomb assembly 92.

[0152] Referring to Figures 20 and 21, in some embodiments, the photographic lamp assembly 100 further includes a support base 30, which includes a mounting rod 31 and a mounting arm 32 disposed on the mounting rod 31. The end of the mounting arm 32 away from the mounting rod 31 is rotatably connected to the outer surface of the lampshade body 10, allowing the lampshade body 10 to rotate within the support base 30 to change the light emission angle.

[0153] In summary, this application provides a photographic light assembly 100 and a photographic lighting system, which includes a lampshade body 10 and a lens 91 disposed on the end face of the light outlet 102 of the lampshade body 10. The lens 91 covers the light outlet 102 of the lampshade body 10 to form a barrier between the interior of the lampshade body 10 and the external environment. The lens 91 isolates the lampshade body 10 from the external space, preventing dust and insects from entering the interior of the lampshade body 10, effectively ensuring the smoothness of its inner reflective surface, thereby ensuring the reflection efficiency and illumination effect of the photographic light assembly 100.

[0154] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
