Technical Field

[0002] The utility model relates to the technical field of photographic equipment, in particular to a photographic light assembly and a photographic lighting system. Background Art

[0003] In some outdoor shooting situations nowadays, it is often necessary for photographic lights to emit nearly parallel light to a distance, so it is necessary to install a large reflector or soft light cover on the photographic light.

[0004] After adding a reflector or softbox to the end of the video light, the light emitted by the video light can be reflected by the inner reflective surface of the reflector or softbox and become parallel light, and then emitted to a distance to achieve the lighting effect of parallel light.

[0005] However, if Figure 1 As shown, part of the light emitted by the photographic light will be emitted directly from the front end surface of the reflector or the soft light cover without being reflected by the reflective surface. This part of the directly emitted light will form a divergent light area on the periphery of the parallel light area. Therefore, the uniformity of the illuminated surface is poor, which seriously affects the illumination effect of the photographic light and further affects the imaging effect of the shooting. It cannot meet the needs of shooting well. Utility Model Content

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0046] See Figures 2 to 5 An embodiment of the present application provides a photographic light assembly 100 for connecting 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 openings at the ends of the lampshade body 10 are parallel and arranged along the same axis as the light inlet 101 and the light outlet 102. The end surface of the lampshade body 10, which is provided with the light inlet 101, is used to connect to the light source 200. The inner wall of the lampshade body 10 is a reflective surface 103. From the light inlet 101 toward the light outlet 102, the reflective surface 103 extends in a gradually expanding parabolic shape. Light emitted by the light source 200 is reflected by the reflective surface 103 to form parallel light perpendicular to the plane of the light outlet 102.

[0048] Two points with a phase difference of 180° on the orthographic projection plane parallel to the light inlet 101 and the light outlet 102 correspond to the set of connecting lines of the points on the outer diameter edge of the light inlet 101 and the outer diameter edge of the light outlet 102, respectively, and are enclosed by the reflecting surface 103 to form a reflecting area 105.

[0049] The light shielding unit 20 is disposed within the lampshade. Its diameter is smaller than that of the light outlet 102. The light shielding unit 20 is capable of blocking light emitted by the light source 200. The center of the light shielding unit 20 is coaxial with the center of the light inlet 101. The cross-section of the light shielding unit 20 gradually increases as the light inlet 101 approaches the light outlet 102.

[0050] The light shielding unit 20 is disposed in the reflective area 105 , and the peripheral edges of the light shielding unit 20 are all tangent to the set intersection line 104 of the reflective area 105 .

[0051] In some embodiments of the present application, the photographic light assembly 100 further includes a support base 30. The support base 30 may be C-shaped, with both ends of the opening of the support base 30 connected to two sides of the outer wall of the lampshade body 10 respectively.

[0052] In some examples, the lampshade body 10 can be rotatably connected to the support base 30. The lampshade body 10 can be rotated relative to the lampshade body 10 to adjust the illumination angle of the light source 200.

[0053] In some embodiments of the present application, the lampshade body 10 may include a shade body 11 and an inlet end surface 12 and an outlet end surface 13 connected to both ends of the shade body 11. The inlet end surface 12 is provided with a light inlet 101, and the outlet end surface 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 video light assembly 100 may further include a connecting arm 40, which is disposed on the outer wall of the inlet end surface 12. One end of the connecting arm 40 is connected to the lampshade 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 lampshade body 10, so that light emitted by the light source 200 can enter the interior of the lampshade body 11 through the light inlet 101.

[0055] The inner wall of the cover 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 perpendicular to the plane where the light outlet 102 is located.

[0056] In some examples, the cross-section of the lampshade body 10 is circular along the axis of the lampshade body 10. The cross-section of the lampshade body 10 gradually increases in area from the light inlet 101 toward the light outlet 102. That is, the light inlet 101 of the lampshade body 10 of this embodiment is a small opening, and the light outlet 102 of the lampshade body 10 is a large opening. As the light inlet 101 moves closer to the light outlet 102, the lampshade body 10 gradually expands.

[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 arrangement enables the light emitted from the light source 200 mounted on the lampshade body 10 to be effectively reflected inside the lampshade body 10 and effectively reflected by the reflecting surface 103, thereby ensuring the light emitting effect of the light source 200 and improving the light emitting efficiency of parallel light.

[0059] See Figure 5 In some embodiments of the present application, two points distributed 180° apart on the edge of the light inlet 101 of the lampshade body 10 serve as inlet setting points, and the line connecting the two inlet setting points serves as the inlet setting line. Two points distributed 180° apart on the edge of the light outlet 102 serve as exit setting points, and the line connecting the two exit setting points serves as the exit setting line. The inlet setting line and the exit setting line are arranged perpendicularly.

[0060] The edge of the light inlet 101 may include multiple groups of inlet set points, and the edge of the light outlet 102 may include multiple groups of outlet set points. Each group of inlet set points includes two inlet set points distributed at 180 degrees, and each group of outlet set points includes two outlet set points distributed at 180 degrees.

[0061] Two intersecting set intersection lines 104 can be formed between the two import set points in each group of import set point groups and the two exit set points in each group of exit set point groups. The multiple set intersection lines 104 formed by multiple groups of import set point groups and multiple groups of exit set point groups can be enclosed with the reflection surface 103 to form a reflection area 105.

[0062] The intersection line 104 is set as two points with a phase difference of 180° on the orthographic projection plane parallel to the light inlet 101 and the light outlet 102, which correspond to the connecting line of the points on the outer diameter edge of the light inlet 101 and the outer diameter edge of the light outlet 102 respectively.

[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 reflective region 105, and the peripheral edges of the light shielding unit 20 are all tangent to the predetermined intersection line 104 of the reflective region 105, so that the light shielding unit 20 can absorb light emitted by the light source 200 but not reflected by the reflective surface 103. In other words, the light shielding unit 20 can absorb light outside the reflective region 105, thereby preventing this portion of light from being directly emitted to the outside through the light outlet 102.

[0064] Combine Figure 3 and Figure 4 In some embodiments of the present application, the shading unit 20 includes a plurality of annular shading members 21, which are concentrically arranged and spaced apart. The peripheral edge of each shading member 21 is tangent to the predetermined intersection line 104 of the reflective area 105. In some examples, the outer contour of the shading member 21 is circular.

[0065] Along the diameter of the light shielding unit 20, the plurality of light shielding members 21 are spaced apart from each other in ascending order of diameter from the inside out. Along the diameter of the light shielding unit 20, the plurality of light shielding members 21 are arranged in decreasing length from the inside out. In some examples, the end surfaces of the plurality of light shielding members 21 facing the light outlet 102 are flush.

[0066] The shading unit 20 is configured as a structure in which multiple shading members 21 are concentrically and spaced apart, so that the parallel light emitted by the light source 200 can be emitted in parallel from the inside of the shading member 21 and the gap between two adjacent shading members 21, thereby preventing this part of the light from being absorbed by the shading unit 20, thereby ensuring the light output efficiency of the parallel light.

[0067] In some embodiments of the present 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 provided 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 the present 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 shading member 21 can be set to 50 mm-100 mm, and the distance between two adjacent shading members 21 can be set to 20 mm-50 mm.

[0069] In some embodiments of the present application, the shading unit 20 may further include a connecting member 22 , and the connecting member 22 is disposed between two adjacent shading members 21 .

[0070] The connecting member 22 may be made of a light absorbing material, or a light absorbing material may be coated on the surface of the connecting member 22. A plurality of connecting members 22 may be provided, and the plurality of connecting members 22 may be arranged in the same diameter direction of the light shielding member 21.

[0071] In some examples, the photographic light assembly 100 further includes a bracket 50 , one end of the bracket 50 is connected to the shading unit 20 , and the other end of the bracket 50 is connected to the inner wall of the inlet end surface 12 of the lampshade body 10 .

[0072] The number of brackets 50 can be multiple, such as two, three, or five. The number of brackets 50 is not particularly limited and can be set based on actual use and design requirements. Multiple brackets 50 can ensure the stability of the shading unit 20 within the lampshade body 10 and ensure that the shading unit 20 effectively blocks and absorbs light.

[0073] See Figure 6 and Figure 7 In some embodiments of the present application, the shading unit 20 is 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 reflective region 105, and the peripheral edges of the light shielding unit 20 are all tangent to the predetermined intersection line 104 of the reflective region 105, so that the light shielding unit 20 can absorb light emitted by the light source 200 but not reflected by the reflective surface 103. In other words, the light shielding unit 20 can absorb light outside the reflective region 105, thereby preventing this portion of light from being directly emitted to the outside through the light outlet 102.

[0075] like Figure 8 and Figure 9 As shown, in some embodiments of the present application, the shading unit 20 is a circular sheet structure. In this example, the shading unit 20 is relatively thin and is in the shape of a thin sheet as a whole.

[0076] The light shielding unit 20 can be made of a light absorbing material, or a light absorbing material can be provided on the surface of the light shielding unit 20. The light shielding unit 20 can be connected to the inner wall of the inlet end surface 12 of the lampshade body 10 through a bracket 50.

[0077] The light shielding unit 20 is disposed in the reflective region 105, and the peripheral edges of the light shielding unit 20 are all tangent to the predetermined intersection line 104 of the reflective region 105, so that the light shielding unit 20 can absorb light emitted by the light source 200 but not reflected by the reflective surface 103. In other words, the light shielding unit 20 can absorb light outside the reflective region 105 to prevent this portion of light from being directly emitted to the outside through the light outlet 102.

[0078] In some other examples, the shading unit 20 may be configured in a cone shape, with its small end facing the light inlet 101 of the lampshade 10 and its large end facing the light outlet of the lampshade 10 .

[0079] See Figures 10 to 12 In some embodiments of the present application, the photographic light assembly 100 further includes a light shielding ring 60 , which is disposed at the light outlet 102 of the lampshade body 10 .

[0080] The light shielding ring 60 can be made of a light shielding material, or a light absorbing material can be provided on the surface of the light shielding ring 60 so that the light shielding ring 60 can absorb the light emitted by the light source 200 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 plug-in rod 62 , and the plug-in rod 62 is disposed on the inner wall of the ring body 61 .

[0082] The photography light assembly 100 also includes a connecting column 70 connected to the exit end face 13 of the lampshade body 10. The connecting column 70 is provided with a connecting hole 71, and the plug-in rod 62 is inserted into the connecting hole 71, so that the light shielding ring 60 is connected to the light outlet 102 of the lampshade body 10.

[0083] Furthermore, if Figure 13 As shown, the present application further provides a photographic lighting system 1000, which includes a light source 200 and the above-mentioned photographic lighting assembly 100. The structure of the photographic lighting 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 surface 12 of the lampshade body 10 via a connecting arm 40. Light emitted by the light source 200 enters the lampshade body 10 through the light inlet 101. After being reflected by the reflective surface 103 and absorbed by the light shielding unit 20, it is emitted through the light outlet 102 as parallel light perpendicular to the plane of the light outlet 102.

[0085] See Figure 14 and Figure 15In some examples, the lampshade body 10 can also be a soft light cover, and a soft light cloth 80 is provided at the light outlet 102 of the soft light cover. The soft light cloth 80 can soften the light, making the parallel light softer and improving the lighting effect.

[0086] The photographic light assembly and photographic lighting system of the present application include a lampshade body and a shading 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. The shading unit is arranged in the reflective area. The peripheral edges of the shading unit are tangent to the set intersection line of the reflective area, so that the shading unit can absorb the light emitted by the light source but not reflected by the reflective surface, thereby effectively reducing the amount of non-parallel light contained in the light emitted from the lampshade body, thereby improving the uniformity of the entire illuminated surface, effectively enhancing the imaging effect of the shooting, and efficiently meeting the user's shooting needs.

[0087] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
