Description

Technical Field

[0001] The present application relates to the technical field of lighting fixtures, and more specifically, to a reflective cup and a lighting fixture. Background Art

[0002] In the prior art, the floodlighting method of lighting fixtures generally uses a reflective cup to distribute light. The structure of the reflective cup is as follows Figure 1 and Figure 2 As shown, it can focus the light emitted by the light source to a desired range. At the same time, some lighting fixtures, such as flashlights, need to ensure that the light emission angle is narrow enough in their application scenarios.

[0003] When the emission angle of the lighting fixture is narrow, the shape of the light spot formed after the emitted light is imaged is the same as the shape of the light emitting surface of the light source. For example, when the light emitting surface of the light source is square, the outline of the light spot will also be square to a certain extent.

[0004] Based on the above problems, the reflective cup of the existing lighting fixture cannot ensure that the shape of the light source of the lighting fixture is circular, thereby affecting the lighting effect of the lighting fixture. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present application is that the existing reflective cup cannot adjust the shape of the light source of the lighting fixture.

[0006] In order to solve the above technical problems, the embodiments of the present application adopt the following solutions:

[0007] A reflective cup, wherein the inner wall of the reflective cup is provided with a smooth area and a textured area;

[0008] The surface of the smooth area is a smooth curved surface, and the textured area is provided with a plurality of raised textures.

[0009] Furthermore, the pattern areas are distributed on the inner wall in an axisymmetric manner about the central axis of the reflective cup.

[0010] Furthermore, the reflective cup further comprises a reinforcement portion and a rib portion, wherein the reinforcement portion is sleeved on the outer wall of the reflective cup, and an accommodating cavity is formed between the inner wall of the reinforcement portion and the outer wall of the reflective cup;

[0011] The rib portion is located in the accommodating cavity and connects the inner wall of the reinforcement portion and the outer wall of the reflective cup.

[0012] Furthermore, there are multiple ribs, and the multiple ribs are axially symmetrically distributed along the central axis of the reflective cup.

[0013] Furthermore, the textured area is arranged from the bottom of the reflective cup toward the opening of the reflective cup.

[0014] Furthermore, the area ratio of the textured region to the inner wall of the reflective cup is greater than 1%.

[0015] Furthermore, the raised patterns include at least one or more of striped raised patterns, quadrilateral raised patterns, diamond-shaped raised patterns, circular raised patterns, triangular raised patterns, and sun-wrinkled raised patterns.

[0016] Furthermore, the cross-sectional area of ​​the inner wall of the reflective cup gradually increases from the bottom to the cup opening, and the area A1 of a single raised pattern gradually increases from the bottom to the opening of the reflective cup; or,

[0017] The cross-sectional area of ​​the inner wall of the reflective cup gradually decreases from the bottom to the cup opening, and the area A1 of a single raised pattern gradually decreases from the bottom to the opening of the reflective cup.

[0018] Furthermore, the distance between adjacent raised lines is less than 10 mm.

[0019] Correspondingly, a lighting fixture is also provided, comprising a light source and a reflective cup, wherein the light source is arranged inside the reflective cup and located at the bottom of the reflective cup, and is used to emit light toward the opening of the reflective cup;

[0020] Wherein, the reflective cup adopts the reflective cup described in any one of the above embodiments.

[0021] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0022] Because the inner wall of the reflector cup of this embodiment includes a textured area in addition to a smooth area, and the textured area is composed of multiple raised patterns, light will be deflected to a certain extent after it hits the raised patterns. After being continuously reflected at the rim of the reflector cup, the deflected light has a larger angle of exit. Therefore, after the angle of exit of this part of light is magnified, the final illuminated light spot can be made circular, thereby overcoming the problem of the edge contour of the square light spot.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0047] In this application, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of a device in actual use or operation, specifically in the drawing directions of the accompanying drawings; whereas "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "including" means "including but not limited to." Terms such as first, second, and third are used merely as designations and do not impose numerical requirements or establish a sequential order.

[0048] In this application, "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0049] In this application, "at least one" means one or more, and "plurality" means two or more. "At least one", "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can all mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be single or multiple.

[0050] Various embodiments of the present application may be presented in the form of a range; it should be understood that the description in the form of a range is only for convenience and brevity and should not be construed as a hard limitation on the scope of the present application; therefore, the range description should be considered to have specifically disclosed all possible sub-ranges and single numbers within the range. For example, the description of a range from 1 to 6 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within the range, such as 1, 2, 3, 4, 5 and 6, which applies regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any cited number (fractional or integer) within the indicated range. Figure 9 The Z direction is the length direction of the reflective cup 10 , and is also the light emitting direction of the reflective cup 10 .

[0051] Please refer to the attached Figures 5-10 This embodiment provides a reflective cup 10 , wherein the inner wall 110 of the reflective cup 10 is provided with a smooth area 101 and a textured area 102 ;

[0052] The surface of the smooth area 101 is a smooth curved surface, and the textured area 102 is provided with a plurality of raised textures.

[0053] First, please refer to Figures 1 to 2 In the prior art reflective cup, the light emitted by the light source is in a divergent state, so not all the light is directly irradiated to the cup opening 130 of the reflective cup 10, and some of the light directly passes through the cup opening 130, while most of the light needs to be reflected or refracted multiple times inside the reflective cup 10 before passing through the cup opening 130. Therefore, please refer to Figure 3 In the prior art, the entire interior of the reflective cup 10 is a smooth area 101, and the surface of the smooth area 101 is a smooth curved surface or a flat surface. At this time, the light path of part of the light emitted by the light source in the smooth area 101 is shown in the figure, which is very dense. Therefore, the shape of the final emitted light spot is similar to the shape of the light source. When the light source is a square light source, see Figure 4 The final light spot has a square outline, which does not meet the actual usage requirements and there are areas where the brightness drops sharply.

[0054] Please continue to refer to Figure 5 and Figure 6 Since the inner wall 110 of the reflective cup 10 of this embodiment includes a textured area 102 in addition to the smooth area 101, and the textured area 102 is composed of a plurality of raised textures, the light will deviate to a certain extent after being irradiated by the raised textures, forming the following Figure 5 The deflected light path shown. Figure 6 It can be seen that after the deflected light path is continuously reflected to the cup mouth 130 of the reflective cup 10, its exit angle is relatively large, and because the light refracted in the reflective cup 10 is mainly the light close to the edge of the light source, that is, the light that is finally formed is mainly square. Therefore, after the exit angle of this part of light is magnified, the final irradiated light can be Figure 6 Obviously, the light spot formed by the reflective cup 10 of this embodiment overcomes the problem of square edge contour compared with the light spot formed by the prior art.

[0055] For further information, please refer to Figures 5 to 10 The patterned areas 102 are symmetrically distributed on the inner wall 110 about the central axis of the reflective cup 10 .

[0056] In this embodiment, when the textured area 102 and the smooth area 101 are arranged opposite to each other, the light may be reflected in the textured area 102 and then immediately reflected in the smooth area 101. In this case, the refraction path of the light will be difficult to control, which may result in an abnormal shape of the final light spot. Therefore, in this embodiment, the textured area 102 is located with the central axis of the reflective cup 10 (parallel to the center of the reflective cup 10). Figure 9 The Z axis) is symmetrically distributed on the inner wall 110. At this time, the texture area 102 forms a ring, which can make the light reflect at the relative position in the ring area, thereby avoiding abnormal spot shape.

[0057] For further information, please refer to Figures 19 to 20 The reflective cup 10 further includes a reinforcement portion 150 and a rib portion 140 . The reinforcement portion 150 is sleeved on the outer wall of the reflective cup 10 . An accommodating cavity is formed between the inner wall 110 of the reinforcement portion 150 and the outer wall of the reflective cup 10 .

[0058] The rib portion 140 is located in the accommodating cavity and connects the inner wall 110 of the reinforcement portion 150 and the outer wall of the reflective cup 10 .

[0059] In the prior art, the reflector 10 has a low structural strength and is easily deformed during use, which in turn causes the shape of the light emitted from the reflector 10 to change and fail to maintain a circular shape. Therefore, in order to ensure that the shape of the light emitted from the reflector 10 is circular, the structural strength of the reflector 10 needs to be increased.

[0060] In this embodiment, the reinforcement portion 150 is sleeved onto the outer wall 120 of the reflector 10, significantly thickening the outer wall 120 of the reflector 10. This thickening is located at the rim 130, which is not supported by the bottom 200, effectively preventing deformation of the rim 130. As for the bottom 200 of the reflector 10, it is generally supported by the bottom 200 of the reflector 10 as the side wall of the reflector 10 and is therefore generally less susceptible to deformation.

[0061] At the same time, the presence of the ribs 140 can effectively further strengthen the connection between the reinforcement portion 150 of the reflector 10 and the reflector 10, thereby increasing the structural strength between the two. Furthermore, when the reflector 10 is trumpet-shaped, the reinforcement portion 150 of the present application is not formed by directly thickening the sidewall of the reflector 10. Instead, the length of the reinforcement portion 150 is parallel to the length of the reflector 10. In this case, a receiving cavity is formed between the outer wall 120 of the reflector 10 and the reinforcement portion 150. This receiving cavity can reduce the material consumption of the reflector 10 and also allow the ribs 140 to have a certain elastic deformation to prevent the reflector 10 from breaking due to excessive rigid stress, thereby improving the instantaneous force tolerance of the reflector 10.

[0062] For further information, please refer to Figures 19 to 20 There are multiple ribs 140, and the ribs 140 are symmetrically distributed along the central axis of the reflector 10. In this case, the provision of multiple ribs 140 allows all parts of the reflector 10 to withstand pressure, that is, improves the overall structural strength of the reflector 10 and prevents damage due to the lack of ribs 140 in a certain part of the reflector 10.

[0063] For further information, please refer to Figures 5 to 10 , the spacing between adjacent raised lines is less than 0.5mm.

[0064] In this embodiment, too large a spacing between adjacent raised patterns will cause light to refract within the gaps between them, affecting the final light spot shape. However, too small a spacing between adjacent patterns will increase the processing cost of the raised patterns. In this embodiment, a spacing of less than 0.5 mm can improve the integrity of the final circular light spot shape while avoiding increased processing costs.

[0065] For further information, please refer to Figures 5 to 10 The pattern area 102 is arranged from the bottom 200 of the reflective cup 10 toward the opening of the reflective cup 10 .

[0066] In this embodiment, if the light first contacts the smooth area 101 and then contacts the textured area 102, since the reflection angle of the smooth area 101 is not the angle required by this embodiment to make the light be straight, even if the light enters the textured area 102 after being reflected by the smooth area 101, part of the light will be deflected.

[0067] If the light first contacts the textured area 102 and then the smooth area 101, the shape of the resulting light spot and the central illumination intensity can be adjusted to meet preset values ​​by varying the surface area and degree of the protrusions of the textured area 102. In summary, this embodiment allows light to be reflected by the textured area 102 upon initial contact with the inner wall 110 of the reflective cup 10, thereby making the shape and size of the light spot controllable.

[0068] For further information, please refer to Figures 5 to 10 The area ratio of the textured region 102 to the inner wall 110 of the reflective cup 10 is greater than 5%.

[0069] Obviously, the larger the area of ​​the textured region 102, the smaller the central illumination intensity of the light, and the closer the shape of the light spot is to a circle. Therefore, in this embodiment, the area ratio of the textured region to the inner wall 110 of the reflective cup 10 is greater than 5%, which can improve the shape of the final light spot to be circular.

[0070] For further information, please refer to Figures 11 to 18 The raised patterns include at least one or more combinations of striped raised patterns, quadrilateral raised patterns, prismatic raised patterns, circular raised patterns, triangular raised patterns, and sun-wrinkled raised patterns.

[0071] For further information, please refer to Figures 7 to 18 The cross-sectional area of ​​the inner wall 110 of the reflective cup 10 gradually increases from the bottom 200 to the cup opening 130 of the reflective cup 10 , and the area A1 of a single raised pattern gradually increases from the bottom 200 to the opening of the reflective cup 10 .

[0072] In this embodiment, to ensure that the light emitted from the reflector 10 meets lighting requirements, the central intensity of the light cannot be too high. Therefore, the inner wall 110 of the reflector 10 is generally designed to be trumpet-shaped, that is, the cross-sectional area of ​​the inner wall 110 gradually increases from the bottom 200 of the reflector 10 to the rim 130 of the reflector 10. In this case, if the area of ​​the raised patterns remains unchanged, the spacing between the raised patterns will increase, resulting in a decrease in the amount of light effectively reflected and an increase in production costs.

[0073] Therefore, in this embodiment, the area of ​​a single raised pattern increases along with the cross-sectional area of ​​the inner wall 110 of the reflector 10 , thereby ensuring that the light reflected by the reflector 10 is on a preset light path, thereby ensuring that the final light spot is circular and the light intensity is balanced everywhere.

[0074] Similarly, when the cross-sectional area of ​​the inner wall of the reflector gradually decreases from the bottom to the rim of the reflector, and the area A1 of each raised pattern gradually decreases from the bottom to the rim of the reflector, it is possible to avoid a decrease in the spacing between the raised patterns, which would result in an unexpected amount of effectively reflected light and an increase in production costs.

[0075] Accordingly, the present application also provides a lighting fixture, which includes a light source and the reflector cup 10 in the above embodiment. The light source is disposed inside the reflector cup 10 and located at the bottom 200 of the reflector cup 10. The light source is used to emit light toward the opening 130 of the reflector cup 10.

[0076] The reflective cup 10 is any of the reflective cups 10 in the above embodiments. Since the lighting fixture includes the reflective cup in the above embodiments, it can ensure that the emitted light is circular and has uniform light intensity.

The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application.
