DETAILED DESCRIPTION
[0043] To make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.
[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0045] As Figure 1 and Figure 2 shown, the present application provides a light distribution member 1, comprising a light-incident surface 11 and a light-outgoing surface 12, at least one of the light-incident surface 11 and the light-outgoing surface 12 is provided with a plurality of protruding portions 13, and the plurality of protruding portions 13 are arrayed. The protruding portions 13 comprise a plurality of refractive surfaces 14.
[0046] When the light rays pass through the light distribution member 1, the arrayed protruding portions 13 make the light rays uniformly distributed, and the light rays are uniformly diffused in all directions by the refractive surfaces 14 of the protruding portions 13, thereby reducing the occurrence of local glare and local shadow, and further improving the uniformity of the illumination intensity.
[0047] The protruding portions 13 include a plurality of refractive surfaces 14 that change the exit angle of the light rays, reduce glare, and provide a unique visual effect. When viewed from different angles, the light distribution piece 1 can exhibit a sparkling multi-faceted reflection effect.
[0048] Before the embodiments of the present application are described in detail, the application scenarios of the embodiments of the present application are first described.
[0049] The light distribution piece 1 provided by the present application can be used in any scenario that requires changing the propagation angle of light. For example, the light distribution piece 1 provided by the present application can be used in the fields of indoor and outdoor lighting, automobiles, electronic equipment, stage lighting, optical instruments, etc. Specifically, it can be used in ceiling lamps, chandeliers, wall lamps, reading lamps, atmosphere lamps, etc. It can also be used in outdoor lamps such as street lamps and signal lamps. It can also be used in automobile headlamps, tail lamps, turn signals, etc.
[0050] The arrangement of the plurality of protruding portions 13 also helps to regularly control the refraction angle of the light.
[0051] For example, the plurality of protruding portions 13 are arranged in an array, and adjacent two protruding portions 13 can be connected or arranged at intervals.
[0052] For example, the plurality of protruding portions 13 are arranged in a parallelogram array. The plurality of protruding portions 13 can also be arranged in a ring array.
[0053] For example, the plurality of protruding portions 13 are arranged on the light entrance surface 11, which can increase the effective optical area of the light entrance surface 11 and improve the uniformity of the illumination intensity.
[0054] In the process of the light passing through the light distribution piece 1, the light is first uniformly dispersed by the plurality of protruding portions 13 of the light entrance surface 11, and then the dispersed light is refracted by the refractive surfaces 14. The refracted light passes through the body of the light distribution piece 1 and then exits through the light exit surface 12.
[0055] For example, continuing to refer to Figure 1 and Figure 2 The light exit surface 12 is provided with a plurality of protruding portions 13, which can increase the effective optical area of the light exit surface 12 and improve the uniformity of the illumination intensity.
[0056] In the process of the light passing through the light distribution piece 1, the light first passes through the light entrance surface 11, then passes through the body of the light distribution piece 1, and then passes through the light exit surface 12. In the process of passing through the light exit surface 12, the light is uniformly dispersed by the plurality of protruding portions 13, then refracted by the refractive surfaces 14, and then emitted.
[0057] Exemplarily, a plurality of protruding portions 13 are arranged on the light-incident surface 11 and the light-emanating surface 12. When the light distribution member 1 is viewed from different angles, the plurality of refracting surfaces 14 of the light-incident surface 11 can be seen through the plurality of protruding portions 13 of the light-emanating surface 12, so that the light distribution member 1 has a more sparkling effect.
[0058] In the process of the light passing through the light distribution member 1, the light is refracted by the plurality of refracting surfaces 14 of the light-incident surface 11, and then is refracted by the plurality of refracting surfaces 14 of the light-emanating surface 12 before being emitted.
[0059] Exemplarily, one refracting surface 14 of the light-emanating surface 12 is arranged opposite to and parallel to one refracting surface 14 of the light-incident surface 11.
[0060] When the light enters the light distribution member 1 from the air, the light is refracted at the light-incident surface 11 due to the change of the medium of the propagating light. When the refracted light enters the air from the light distribution member 1, the light is refracted again at the light-emanating surface 12 due to the change of the medium of the propagating light. Since one refracting surface 14 of the light-emanating surface 12 is parallel to one refracting surface 14 of the light-incident surface 11, the refracting angle of the light is the same in the two times of refraction, so that the light entering the light distribution member 1 is parallel to the light emitted from the light distribution member 1. Thus, the light can be conveniently irradiated to the area to be illuminated.
[0061] Exemplarily, the material of the light distribution member 1 includes but is not limited to polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), glass, and silica gel.
[0062] Exemplarily, the light distribution member 1 can be prepared by injection molding.
[0063] In a possible implementation, continuing to refer to Figure 1 and Figure 2 , the protruding portion 13 is conical.
[0064] The conical protruding portion 13 makes the surface of the light distribution member 1 have visual depth, and presents a visual effect with rich levels, thereby improving the texture of the light distribution member 1.
[0065] The refracting surfaces 14 of the conical protruding portion 13 all intersect at a point. When the light is refracted by the refracting surfaces 14, a sparkling effect similar to that of a diamond can be produced, thereby improving the visual effect and texture of the light distribution member 1.
[0066] In a possible implementation, the protruding portion 13 is prismatic.
[0067] Since the edges of the prismatic bottom surface are curved, the prismatic protruding portions 13 can better fit together when arranged on a plane, that is, the protruding portion 13 is prismatic, which facilitates the connection of adjacent protruding portions 13.
[0068] In a possible implementation, the protruding portion 13 is in the shape of a boss.
[0069] In this way, the convex portion 13 has a convex plane which is perpendicular to the light, and the light passing through the convex plane will not be refracted, thereby producing a more abundant visual effect.
[0070] In one possible implementation, continuing to refer to Figure 1 and Figure 2 , the convex portion 13 includes 3-7 refractive surfaces 14, and each convex portion 13 includes the same number of refractive surfaces 14.
[0071] The number of refractive surfaces 14 included in each convex portion 13 is the same, which can make the light have consistency and repeatability in the refraction process through the convex portion 13, thereby facilitating the irradiation of light to a predetermined area.
[0072] For example, the number of refractive surfaces 14 included in the convex portion 13 can be one of 3, 4, 5, 6, and 7. By setting different numbers of refractive surfaces 14, different refraction effects can be produced.
[0073] The application also provides a light assembly 100, as shown in Figure 3 and Figure 4 , the light assembly 100 includes a light source 2 and the light distribution member 1 provided by any one of the embodiments described above. The light generated by the light source 2 can be emitted through the light distribution member 1.

[0076] For example, the light source 2 can be at least one of an incandescent lamp, a fluorescent lamp, a light-emitting diode (LED), and a halogen lamp.
[0077] In one possible implementation, the light source 2 further includes a PCB board and a light-emitting diode (LED), and the light-emitting diode (LED) is arranged on the PCB board. The light source 2 is used to provide logo light energy.
[0078] The number of light sources 2 is multiple, and the multiple light sources 2 are arranged at intervals and uniformly, so as to make the light uniform.

The light source piece 2 and the light distribution piece 1 are both arranged in the receiving cavity 61, and the transparent piece 7 is located on the side of the light distribution piece 1 away from the light source piece 2.
[0080] In the case that the light generated by the light source piece 2 passes through the transparent piece 7, the housing 6 and the transparent piece 7 provide protection for the light source piece 2 and the light distribution piece 1, reducing damage to the light source piece 2 and the light distribution piece 1 from the outside.
[0081] Illustratively, the material of the transparent piece 7 includes but is not limited to polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), glass, and silicone.
[0082] In one possible implementation, the surface of the transparent piece 7 can be sprayed with a wear-resistant layer to improve the wear resistance of the transparent piece 7.
[0083] The connection mode of the transparent piece 7 and the housing 6 includes but is not limited to at least one of bolt connection, clamping, plug-in connection, snap connection, magnetic connection, adhesive bonding, welding, and one-piece forming.
[0084] Illustratively, the housing 6 is provided with a matching groove, and the transparent piece 7 can be plug-in connected to the matching groove after an adhesive is arranged in the matching groove. In this way, the transparent piece 7 is connected with the housing 6 while the adhesive has a sealing effect, preventing impurities such as water and dust from entering the receiving cavity 61, thereby improving the cleanliness of the receiving cavity 61 and the service life of the light assembly 100.
[0085] In one possible implementation, the light assembly 100 further comprises a decorative piece 9. The decorative piece 9 is used to mount the transparent piece 7.
