Description

[0001] This application claims priority to Chinese Patent Application No. 202410513715.0, filed on April 26, 2024, entitled "Photographic Light Assembly and Photographic Lighting System", and Chinese Patent Application No. 202420896433.9, filed on April 26, 2024, entitled "Photographic Light Assembly and Photographic Lighting System", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of photographic and video equipment technology, and in particular to a photographic light assembly and a 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 Figure 1 As shown, some of the light emitted by the photographic light source will be emitted directly from the front surface of the reflector or diffuser without being reflected by the reflective surface. This directly emitted light 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 affects the image quality of the photograph, thus failing to 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 one embodiment 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.

[0011] In one embodiment of this application, the minimum diameter of the light-shielding unit is not less than the diameter of the light inlet.

[0012] In one embodiment of this application, the light-shielding unit is a disc-shaped structure.

[0013] In one embodiment of this application, the light-shielding unit includes a plurality of annular light-shielding members, which are arranged concentrically and at intervals; the peripheral edge of each light-shielding member is tangent to a predetermined intersection line of the reflective area.

[0014] In one embodiment of this application, in the diameter direction of the light-shielding unit, a plurality of light-shielding members are arranged sequentially from the inside to the outside in order of increasing diameter; in the diameter direction of the light-shielding unit, the length of the plurality of light-shielding members gradually decreases in the arrangement order from the inside to the outside.

[0015] In one embodiment of this application, the end faces of the plurality of light-shielding members facing the light-emitting port are flush.

[0016] In one embodiment of this application, the light-shielding unit includes a connector, which is disposed between two adjacent light-shielding units.

[0017] In one embodiment of this application, the photographic light assembly further includes a bracket, one end of which is connected to the light-shielding unit, and the other end of which is connected to the inner wall of the end face of the lampshade body where the light inlet is located.

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

[0019] In one embodiment of this application, the photographic light assembly further includes a light-shielding ring disposed at the light outlet of the lamp cover, the light-shielding ring being able to block the light emitted by the light source.

[0020] In one embodiment of this application, the light-shielding ring includes an annular ring body and a plug rod, the plug 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] The present invention also provides a photographic lighting system, including a light source and the above-mentioned photographic light assembly, wherein the light source is connected to the end face of the lamp cover body 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 one embodiment of this application, the lampshade is a diffuser, and a diffuser cloth is provided at the light outlet of the diffuser.

[0025] In one embodiment of this application, the light source is an LED surface light source.

[0026] 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.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] See Figures 2 to 5 One 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] See 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. 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.

[0060] 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°.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Combination Figure 3 and Figure 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] See Figure 6 and Figure 7 In some embodiments of this application, the light-shielding unit 20 has a disc-shaped structure.

[0074] 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.

[0075] like Figure 8 and Figure 9 As shown, 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] See Figures 10 to 12 In some embodiments of this application, the photographic light assembly 100 further includes a light shield 60, which is disposed at the light outlet 102 of the lamp cover body 10.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] Furthermore, such as Figure 13 As shown, 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.

[0084] 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.

[0085] See Figure 14 and Figure 15In 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.

[0086] The photographic light assembly and system of this application include a lampshade and a light-shielding unit. The inner wall of the lampshade is a reflective surface, which is 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. A reflective area is also formed inside the lampshade, and the light-shielding unit is disposed in the reflective area. The peripheral edges of the light-shielding unit are tangent to the designated 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. This effectively reduces the amount of non-parallel light contained in the light emitted from the lampshade, improves the uniformity of the entire illumination surface, effectively enhances the imaging effect of the shot, and efficiently meets the user's shooting needs.

[0087] 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.
