[0035] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0036] The following will refer to Figures 1 - 6 and describe the present invention in detail in conjunction with embodiments.

[0037] Referring to Figure 1 As shown, according to an embodiment of the present invention, the optical component 100 includes a light-emitting member 10, a light homogenizing member 20, and a light-transmitting member 30.

[0038] The light-emitting member 10 is at least one, and the light-emitting member 10 is used to emit light; the light-transmitting member 30 has a first light-guiding portion 31 and a first light-emitting portion 32; the light homogenizing member 20 has a light homogenizing portion 21 and a second light-guiding portion 22. In the height direction of the light homogenizing member 20, the light homogenizing portion 21 and the light-emitting member 10 at least partially overlap to receive and homogenize the light.

[0039] Wherein, in the length direction of the light homogenizing member 20, the second light-guiding portion 22 and the first light-guiding portion 31 at least partially overlap to guide the light to the first light-guiding portion 31, and the first light-emitting portion 32 corresponds to the first light-guiding portion 31 to guide the light to the first light-emitting portion 32.

[0040] It should be noted that the light-emitting member 10 is a light source, and the light-emitting member 10 emits light; the light-transmitting member 30 and the light homogenizing member 20 are optical elements, and the light homogenizing member 20 guides and processes the light emitted by the light-emitting member 10. For example, the light homogenizing member 20 homogenizes the light emitted by the light-emitting member 10, so that the light is more uniform after passing through the light homogenizing member 20.

[0041] Wherein, referring to Figure 1 As shown, the length direction of the light homogenizing member 20 is the front-back direction, and the height direction of the light homogenizing member 20 is the up-down direction.

[0042] In the above solution, the light-emitting member 10 emits light, the light homogenizing member 20 mixes and homogenizes the light emitted by multiple light-emitting members 10, and then the homogenized light enters the light-transmitting member 30 and is emitted from the first light-emitting portion 32 on the light-transmitting member 30. The emitted light can enter the eyes of an observer or be arranged in other ways.

[0043] Alternatively, the light-emitting member 10 emits light, and the light homogenizing member 20 homogenizes the light emitted by a single light-emitting member 10. For example, the light-emitting member 10 is a Lambertian body, and the light-emitting member 10 emits light in all directions. The light entering the light homogenizing member 20 is homogenized, and then the homogenized light enters the light-transmitting member 30 and is emitted from the first light-emitting portion 32 on the light-transmitting member 30. The emitted light can enter the eyes of an observer or be arranged in other ways.

[0044] Specifically, the light homogenizing member 20 corresponds to the light emitting member 10, so that the light emitting member 10 can be an LED particle, and the LED particle is a point light source. Compared with the strip light source in the related art, space is saved and the cost is reduced.

[0045] Specifically, in the length direction of the light homogenizing member 20, the light homogenizing member 20 is located on the side of the light emitting member 10 facing the light transmissive member 30, and in the height direction of the light homogenizing member 20, the light homogenizing member 20 is located on the side of the light transmissive member 30 facing the light emitting member 10. Referring to Figure 1 As shown in the figure, the light transmissive member 30 is located at the front lower side of the light emitting member 10, the light homogenizing member 20 is located at the front side of the light emitting member 10, and at the same time, the light homogenizing member 20 is located at the upper side of the light transmissive member 30. The light emitted by the light emitting member 10 enters the light homogenizing member 20, and the light emitted by multiple light emitting members 10 is mixed and homogenized in the light homogenizing portion 21, and then enters the light transmissive member 30 under the reflection of the second light guiding portion 22, and then the first light guiding portion 31 reflects the light and guides the light to the first light emitting portion 32, and the light leaves the light transmissive member 30 from the first light emitting portion 32.

[0046] In the related art, a thick wall member corresponds to multiple light sources, the light sources are located above the thick wall member, and the thick wall member is configured in a stepped shape. In order to make the light of multiple light sources mix more evenly, three reflecting surfaces are provided in the thick wall member. The light emitted by the light sources directly enters the thick wall member, and then passes through the three reflecting surfaces in sequence, and the light leaves the thick wall member from the light emitting surface on the front side of the thick wall member. In the above solution, the structure of the thick wall member is complex, resulting in a high cost.

[0047] In the present invention, the light emitted by the light emitting member 10 is homogenized by providing the light homogenizing member 20, and the light homogenizing member 20 and the light emitting member 10 at least partially overlap in the height direction. Compared with the solution in the related art where the light homogenizing member and the light emitting member are arranged in sequence in the height direction, the total height of the light homogenizing member 20 and the light emitting member 10 in the embodiment of the present invention is less than the sum of their individual heights. For example, the height of the light homogenizing member 20 is H1, and the height of the light emitting member 10 is H2. In the related art, the light homogenizing member and the light emitting member are arranged in sequence in the height direction, and the total height of the space occupied by the light homogenizing member and the light emitting member is (H1 + H2). Referring to Figure 1 As shown in the figure, in the embodiment of the present invention, the projection of the light homogenizing member 20 is completely on the light emitting member 10, and the height of the space occupied by the light homogenizing member 20 and the light emitting member 10 in the height direction is H2, and H2 is less than (H1 + H2), thereby reducing the size of the overall occupied space and making the structure more compact.

[0048] Similarly, the light homogenizing member 20 and the light transmissive member 30 at least partially overlap in the length direction. Compared with the related art where the light homogenizing member and the light transmissive member are arranged in sequence in the length direction, the total length of the light homogenizing member 20 and the light transmissive member 30 in the embodiment of the present invention is less than the sum of their individual lengths. For example, the length of the light homogenizing member 20 is B1, and the length of the light transmissive member 30 is B2. In the related art, the light homogenizing member and the light transmissive member are arranged in sequence in the length direction, and the total height of the space occupied by the light homogenizing member and the light transmissive member is (B1 + B2). Referring to Figure 1 As shown, in the embodiment of the present invention, the projected part of the light homogenizing member 20 is on the light emitting member 10, and the length of the space occupied by the light homogenizing member 20 and the light emitting member 10 in the length direction is less than (B1 + B2), thereby reducing the size of the overall occupied space and making the structure more compact.

[0049] In summary, in the case where the optical path lengths are equal, in the embodiment of the present invention, by arranging the spatial relationships of the light emitting member 10, the light homogenizing member 20, and the light transmissive member 30, the size of the overall occupied space is reduced, thereby making the structure more compact. Compared with the related art where multiple reflecting surfaces are provided, in the present invention, the light homogenizing member 20 is added, and at the same time, the relative spatial positions of the light emitting member 10, the light homogenizing member 20, and the light transmissive member 30 are arranged. Compared with the related art where three reflecting surfaces are provided on the thick-walled member to increase the optical path length, in the embodiment of the present invention, a first light guiding portion 31 is provided on the light transmissive member 30, and the light transmissive member 30 does not need to be provided with more reflecting surfaces to increase the optical path length, thereby simplifying the structure of the light transmissive member 30 and reducing the cost.

[0050] Moreover, the first light guiding portion 31 and the second light guiding portion 22 are respectively located on two components. In the related art, if the positional relationship between the three reflecting surfaces needs to be adjusted, the thick-walled member must be processed, such as thinning, grinding, etc. The processing process increases the cost and there is a problem of processing failure. In the present invention, the first light guiding portion 31 and the second light guiding portion 22 are respectively located on two components, which facilitates the adjustment of the positions of the first light guiding portion 31 and the second light guiding portion 22, and the practicality of the present invention is higher.

[0051] According to the optical component 100 of the embodiment of the present invention, by providing the light homogenizing member 20 on one side of the light emitting member 10, and the light homogenizing member 20 is located on one side of the light transmissive member 30, the light of the light emitting member 10 is homogenized by the light homogenizing member 20. Compared with the related art where multiple reflecting surfaces are provided, in the present invention, the light homogenizing member 20 is added, and at the same time, the spatial positions of the light emitting member 10, the light homogenizing member 20, and the light transmissive member 30 are arranged, simplifying the structure of the light transmissive member 30, reducing the cost, and the first light guiding portion 31 and the second light guiding portion 22 are respectively located on two components, which facilitates the adjustment of the positions of the first light guiding portion 31 and the second light guiding portion 22, improving the practicality.

[0052] According to some embodiments of the present invention, the light homogenizing member 20 is a light guide plate or a light homogenizing rod.

[0053] In the above solution, the light homogenizing member 20 is a light guide plate, which converts multiple point light sources into a surface light source by utilizing the characteristics of the light guide plate, improving the uniformity of light and increasing the light range.

[0054] Specifically, the light guide plate is also called a light ray guiding plate, which guides the light rays in the direction required by the designer. The material of the light guide plate can be acrylic or PC board, and light guiding points are printed on the acrylic or PC board. The light guiding points have a very high reflectivity and do not absorb light. After the light rays are refracted and reflected by the light guiding points, they can be evenly emitted from the light guide plate.

[0055] According to some embodiments of the present invention, the length of the light homogenizing portion 21 is at least 20 mm.

[0056] In the above solution, the length of the light homogenizing portion 21 is at least 20 mm. The light rays are refracted and reflected by the light guiding points in the relatively long light homogenizing portion 21, so that the light rays of the light emitting member 10 are fully homogenized. The relatively long distance enables the light rays emitted by multiple light emitting members 10 to be fully homogenized in the light homogenizing portion 21, improving the uniformity.

[0057] Specifically, referring to Figure 1 As shown, the length of the light homogenizing portion 21 is L, and the light rays are fully homogenized in a relatively long light guide plate. For example, the length of the light homogenizing portion 21 is 20 mm; or, the length of the light homogenizing portion 21 is 21 mm; or, the length of the light homogenizing portion 21 is 22 mm; or, the length of the light homogenizing portion 21 is 23 mm; or, the length of the light homogenizing portion 21 is 24 mm; or, the length of the light homogenizing portion 21 is 25 mm; of course, the length of the light homogenizing portion 21 can also be longer, which will not be elaborated here.

[0058] According to some embodiments of the present invention, a plurality of first reflecting surfaces 221 are provided on one side of the second light guide portion 22 in the height direction, and the plurality of first reflecting surfaces 221 are arranged along the length direction. The other side of the second light guide portion 22 in the height direction is configured as a second light emitting portion 222, and the plurality of first reflecting surfaces 221 guide the light rays to the second light emitting portion 222.

[0059] In the above solution, referring to Figure 1 、 Figure 2 As shown, a plurality of first reflecting surfaces 221 are provided on one side of the second light guide portion 22 in the height direction, and a second light emitting portion 222 is provided on the other side. The plurality of first reflecting surfaces 221 correspond to the second light emitting portion 222, and the plurality of first reflecting surfaces 221 guide the light rays to the second light emitting portion 222, increasing the light emitting area.

[0060] For example, referring to Figure 1As shown in the figure, a plurality of first reflecting surfaces 221 are provided on the upper side of the second light guide portion 22. The plurality of first reflecting surfaces 221 are arranged in the front-rear direction. The lower side of the second light guide portion 22 is configured as a second light emitting portion 222. The plurality of first reflecting surfaces correspond to the second light emitting portion 222, and the plurality of first reflecting surfaces 221 guide light to the second light emitting portion 222.

[0061] Among them, on one side of the second light guide portion 22 in the height direction, a plurality of first reflecting surfaces 221 are provided, and on the other side, a second light emitting portion 222 is provided. The plurality of first reflecting surfaces 221 correspond to the second light emitting portion 222, and the plurality of first reflecting surfaces 221 guide light to the second light emitting portion 222. At the same time, it should be noted that in the height direction of the light homogenizing member 20, the light homogenizing portion 21 and the light emitting member 10 at least partially overlap. The light emitted by the light emitting member 10 can irradiate on the plurality of first reflecting surfaces 221, and the plurality of first reflecting surfaces 221 guide the light to the first light emitting portion 32. The plurality of first reflecting surfaces 221 and the light emitting member 10 at least partially overlap in the height direction, which can better correspond to the conduction of light.

[0062] Among them, it should be noted that in the present invention, a plurality of first reflecting surfaces 221 are provided. Even if a single row of light emitting members 10 is provided on one side of the light homogenizing member 20, under the action of the plurality of first reflecting surfaces 221, the light can be extended to the entire second light emitting portion, thereby reducing the cost on the premise of meeting a relatively wide light emitting area. It can be understood that on the premise of a single row of light emitting members 10, by changing the sizes of the second light guide portion 22, the first light guide portion 31 and the first light emitting portion 32, the light emitting area on the second light emitting portion 222 can be of any size.

[0063] For example, there are four light emitting members 10, and the four light emitting members 10 are spaced apart in the left-right direction. The light homogenizing portion 21 corresponds to the four light emitting members 10, so as to mix the light emitted by the four light emitting members 10. The plurality of first reflecting surfaces 221 guide the light to the first light guide portion 31, and the first light guide portion 31 guides the light to the first light emitting portion 32. Among them, regardless of the area of the first light emitting portion 32, only one row of four light emitting members 10 can make light emit from each part of the first light emitting portion 32. That is to say, initially the area of the first light emitting portion 32 is A1, and then if you want to increase the area of the first light emitting portion 32 to A2, you only need to correspondingly change the sizes of the first light guide portion 31 and the second light guide portion 22, without changing the four light emitting members 10, thereby reducing the cost.

[0064] Alternatively, there are six light-emitting elements 10, which are spaced apart in the left-right direction. The light homogenizing part 21 corresponds to the six light-emitting elements 10, so as to mix the light emitted by the six light-emitting elements 10. A plurality of first reflecting surfaces 221 guide the light to the first light guide part 31, and the first light guide part 31 guides the light to the first light-emitting part 32. Among them, regardless of the area of the first light-emitting part 32, only one row of six light-emitting elements 10 can enable light to be emitted from each part of the first light-emitting part 32. That is to say, initially the area of the first light-emitting part 32 is A1, and then if you want to increase the area of the first light-emitting part 32 to A2, you only need to correspondingly change the sizes of the first light guide part 31 and the second light guide part 22, without changing the six light-emitting elements 10, thereby reducing the cost.

[0065] In some specific embodiments, the second light-emitting part 222 is a second light-emitting plane, and the light exits from the second light-emitting plane. That is to say, a plurality of first reflecting surfaces all guide the light to the second light-emitting plane. The second light-emitting part 222 is configured as the second light-emitting plane, and the second light-emitting plane emits light as a whole, and the light is more uniform, improving the uniformity. At the same time, it is convenient for the spatial correspondence between the light homogenizing member 20 and the light-transmitting member 30. It can be understood that the light emitted by the second light-emitting plane is the light emitted by the plane, and the light path of the light emitted by the second light-emitting plane is simple. Therefore, when adjusting the spatial relationship between the light homogenizing member 20 and the light-transmitting member 30, the factor of the light path can be considered less, making the overall layout of the optical component 100 simpler.

[0066] In other specific embodiments, the second light-emitting part 222 is a second light-emitting curved surface, and the light exits from the second light-emitting curved surface. That is to say, a plurality of first reflecting surfaces all guide the light to the second light-emitting curved surface. The second light-emitting part is configured as the second light-emitting curved surface, and the second light-emitting curved surface emits light as a whole, and the light diffuses and emits, and the light-emitting area is larger, the range of the light is larger, and the light can irradiate a larger range, improving the influence range.

[0067] According to other embodiments of the present invention, one side of the second light guide part 22 in the height direction is configured as a second reflecting surface, and in the direction towards the light-emitting element 10, the second reflecting surface extends obliquely upward. The other side of the second light guide part 22 in the height direction is configured as the second light-emitting part 222, and the second reflecting surface guides the light to the second light-emitting part 222.

[0068] In the above solution, one side of the second light guide part 22 in the height direction is configured as the second reflecting surface, and the second reflecting surface is a reflecting surface with a larger area, simplifying the structure.

[0069] In some specific embodiments, the second light-emitting part 222 is a second light-emitting plane, and light rays pass through the second light-emitting plane. That is to say, multiple first reflection surfaces all guide the light rays to the second light-emitting plane. By constructing the second light-emitting part 222 as the second light-emitting plane, the second light-emitting plane emits light as a whole, the light rays are more uniform, the uniformity is improved, and at the same time, the spatial correspondence between the light homogenizing member 20 and the light-transmitting member 30 is facilitated. It can be understood that the light rays emitted by the second light-emitting plane are the light rays emitted by a plane, and the light ray path emitted by the second light-emitting plane is simple. Therefore, when adjusting the spatial relationship between the light homogenizing member 20 and the light-transmitting member 30, the factor of the light ray path can be considered less, making the overall layout of the optical assembly 100 simpler.

[0070] In other specific embodiments, the second light-emitting part 222 is a second light-emitting curved surface, and light rays pass through the second light-emitting curved surface. That is to say, multiple first reflection surfaces all guide the light rays to the second light-emitting curved surface. By constructing the second light-emitting part 222 as the second light-emitting curved surface, the second light-emitting curved surface emits light as a whole, the light rays are diffusely emitted, the light-emitting area is larger, the range of the light rays is larger, the light rays can irradiate a larger range, and the influence range is improved.

[0071] According to some embodiments of the present invention, with reference to Figure 1 、 Figure 2 as shown, multiple tooth parts 223 are provided on the second light guide part 22, and the side surfaces of the tooth parts 223 are configured as first reflection surfaces 221.

[0072] Among them, the multiple tooth parts 223 include: a first tooth part 2231 and a second tooth part 2232. The second tooth part 2232 is located on the side of the first tooth part 2231 away from the light homogenizing part 21. There are multiple first tooth parts 2231, and the distance between two adjacent first tooth parts 2231 is T1. There are multiple second tooth parts 2232, and the distance between two adjacent second tooth parts 2232 is T2, and T1>T2.

[0073] In the above solution, the side surfaces of the tooth parts 223 are used to reflect light rays. The shapes of the tooth parts 223 are relatively uniform, which is convenient for molding and has high reliability.

[0074] At the same time, with reference to Figure 1 、 Figure 2 and Figure 5 as shown, there are multiple first tooth parts 2231, the distance between two adjacent first tooth parts 2231 is T1, there are multiple second tooth parts 2232, and the distance between two adjacent second tooth parts 2232 is T2, and T1>T2, so that the multiple tooth parts 223 are sparse first and then dense in the direction away from the light-emitting part 10, making the light rays passing through the second light-emitting part 222 more uniform, improving the optical effect, and allowing users to observe more uniform bright light.

[0075] Specifically, the first tooth portion 2231 is close to the light-emitting element 10, and the second tooth portion 2232 is farther away from the light-emitting element 10 than the first tooth portion 2231. The first tooth portion 2231 receives more light, and the second tooth portion 2232 receives less light. The sparser multiple first tooth portions 2231 reflect a smaller percentage of light, while the denser multiple second tooth portions 2232 reflect a higher percentage of light. To put it simply, the first tooth portion 2231 receives 10 light rays, and the second tooth portion 2232 receives 5 light rays. The sparser multiple first tooth portions 2231 reflect 40% of the light rays, that is, the reflected light rays are 4, while the denser multiple second tooth portions 2232 reflect 80% of the light rays, that is, the reflected light rays are 4. The light rays reflected by both the first tooth portion 2231 and the second tooth portion 2232 are 4, so that the light rays reflected by the first tooth portion 2231 and the second tooth portion 2232 are more uniform.

[0076] In some specific embodiments, a plurality of teeth 223 are provided on the second light guiding portion 22, and the side surface of the tooth 223 is constructed as a first reflecting surface 221. The plurality of teeth are arranged in sequence in the length direction, that is, the first reflecting surfaces are arranged in sequence in the length direction. The first reflecting surfaces arranged in sequence in the length direction can reflect light to a larger area, thereby increasing the range of influence.

[0077] In some specific embodiments, the distance between any two adjacent teeth 223 gradually decreases in the direction away from the light emitting element 10. That is, the teeth 223 become increasingly dense in the direction away from the light emitting element 10, so that the light reflected by the teeth 223 is uniform.

[0078] Specifically, the plurality of tooth portions 223 include a third tooth portion and a fourth tooth portion. The fourth tooth portion is located on the side of the third tooth portion away from the light-emitting element. The third tooth portion is close to the light-emitting element 10, and the fourth tooth portion is farther away from the light-emitting element 10 than the third tooth portion. The third tooth portion receives more light, and the fourth tooth portion receives less light. The sparser third tooth portion reflects a smaller percentage of light, while the denser fourth tooth portion reflects a higher percentage of light. To put it simply, the third tooth portion receives 10 light rays, and the fourth tooth portion receives 5 light rays. The sparser third tooth portion reflects 40% of the light rays, that is, the reflected light rays are 4, while the denser fourth tooth portion reflects 80% of the light rays, that is, the reflected light rays are 4. The light rays reflected by the third and fourth tooth portions are both 4, thereby making the light rays reflected by the third and fourth tooth portions more uniform.

[0079] According to some embodiments of the present invention, at least a portion of the second light exiting portion 222 corresponds to the first light guiding portion 31 .

[0080] In the above solution, at least part of the second light-emitting part 222 corresponds to the first light guide part 31. That is to say, any part on the first light guide part 31 corresponds to the second light-emitting part 222, so that light can cover the first light guide part 31, avoiding the situation of no light. For example, the optical component 100 is a part of the vehicle lamp device 1000, making the vehicle lamp more beautiful.

[0081] It should be noted that in the length direction of the light homogenizing member 20, at least part of the second light guide part 22 coincides with the first light guide part 31. At the same time, at least part of the second light-emitting part 222 corresponds to the first light guide part 31, so that the second light guide part 22, the first light guide part 31 and at least part of the second light-emitting part 222 are vertically aligned in space, making the overall structure more compact.

[0082] Specifically, the second light-emitting part 222 completely corresponds to the first light guide part 31, and the second light-emitting part 222 exactly corresponds to the first light guide part 31, avoiding the waste of light energy and improving the efficiency.

[0083] Specifically, referring to Figure 1 As shown, the lengths of the second light-emitting part 222, the first light guide part 31 and the second light guide part 22 are equal, and the second light-emitting part 222, the first light guide part 31 and the second light guide part 22 are vertically aligned, so that the structure is compact, avoiding the waste of light energy and improving the efficiency.

[0084] According to some embodiments of the present invention, the light transmissive member 30 has a first side surface 33 and a second side surface 34, and the first side surface 33 and the second side surface 34 are disposed opposite to each other.

[0085] Among them, the first side surface 33 is configured as the first light-emitting part 32, and the second side surface 34 is configured as the first light guide part 31.

[0086] In the above solution, referring to Figure 1 、 Figure 2 As shown, the two opposite side surfaces of the light transmissive member 30 are respectively set as the first light-emitting part 32 and the first light guide part 31, making full use of the shape of the light transmissive member 30, with a smaller overall size, simple and practical, and no need for more processing, thus reducing the cost.

[0087] For example, the front side surface of the light transmissive member 30 is the first side surface 33, and the rear side surface is the second side surface 34. By making full use of the two side surfaces of the light transmissive member 30 in the height direction, the height of the light transmissive member 30 is smaller.

[0088] In the related art, in order to increase the optical path length, the shape of the light transmissive member is complex. The light transmissive member has a first reflecting surface, a second reflecting surface and a third reflecting surface, and the overall shape of the light transmissive member is stepped, and the production process of the light transmissive member is relatively complex. In the embodiments of the present invention, the light transmissive member 30 is columnar as a whole, and the columnar light transmissive member has a simple structure, thus simplifying the production process of the light transmissive member 30 and reducing the cost.

[0089] According to some embodiments of the present invention, the light-transmitting member 30 further has a third side surface 35. The third side surface 35 is adjacent to the first side surface 33 and the second side surface 34 respectively. At least a part of the third side surface 35 is configured as a first light-incident portion 351, and the first light-incident portion 351 corresponds to the second light-emitting portion 222.

[0090] In the above solution, referring to Figure 1 、 Figure 2 As shown, the third side surface of the light-transmitting member 30, that is, the third side surface 35, is configured as the first light-incident portion 351 corresponding to the second light-emitting portion 222. Light enters the light-transmitting member 30 from the first light-incident portion 351. That is to say, the light-transmitting member 30 and the light homogenizing member 20 are two separate components, so as to facilitate the adjustment of the first light-guiding portion 31 and the second light-guiding portion 22, realize incident and reflection at more angles, and provide more optical solutions. For example, the light-transmitting member 30 is fixed, and the light homogenizing member 20 is adjusted to adjust the direction of the light; or, the light homogenizing member 20 is fixed, and the light-transmitting member 30 is adjusted to adjust the direction of the light. The above two solutions can avoid polishing the light-transmitting member 30, thereby reducing the difficulty.

[0091] In some embodiments, the light-transmitting member 30 is located below the light homogenizing member 20, the third side surface 35 is the top surface, and the top surface of the light-transmitting member 30 is configured as the first light-incident portion 351.

[0092] In some other embodiments, the light-transmitting member 30 is located above the light homogenizing member 20, the third side surface 35 is the bottom surface, and the bottom surface of the light-transmitting member 30 is configured as the first light-incident portion 351.

[0093] In some specific embodiments, referring to Figure 1 As shown, the light homogenizing member 20 is provided with a second light-incident portion 23. The second light-incident portion 23 is located on the side of the light homogenizing member 20 facing the light-emitting member 10, and the side surface where the second light-incident portion 23 is located is adjacent to the side surface where the second light-emitting portion 222 is located.

[0094] According to some embodiments of the present invention, there is an included angle between the first light-guiding portion 31 and the first light-incident portion 351, which facilitates the first light-guiding portion 31 to reflect the light and simplifies the structure.

[0095] Specifically, the included angle between the first light-guiding portion 31 and the first light-incident portion 351 is an acute angle, so that the light incident from the first light-incident portion 351 can be better guided to the first light-guiding portion 31, and the first light-guiding portion 31 fully acts on the light, avoiding light loss.

[0096] It should be noted that the included angle between the first light-guiding portion 31 and the first light-incident portion 351 is an acute angle, and the first light-guiding portion 31 is inclined towards the light homogenizing member 20. The first light-guiding portion 31 is close to the light homogenizing member 20, so that the first light-guiding portion 31 can better realize light guiding.

[0097] More specifically, the angle between the first light guide portion 31 and the first light incident portion 351 is 45 degrees. The simple shape facilitates the molding of the light-transmitting member 30 , and the light path is easier to design, thereby reducing design costs.

[0098] According to some embodiments of the present invention, the first light guide portion 31 includes a plurality of reflective arcuate surfaces 311 . The reflective arcuate surfaces 311 extend along the height direction. The plurality of reflective arcuate surfaces 311 are sequentially arranged in the thickness direction of the light homogenizer 20 .

[0099] In the above scheme, refer to Figure 2 、 Figure 4 As shown, multiple reflective arc surfaces 311 extend in the height direction, the arc surface causes the light to diffuse in the thickness direction, and the arc surface causes the light to diffuse in the left and right directions, and multiple reflective arc surfaces 311 are arranged in sequence in the thickness direction of the light homogenizing member 20, and the light diffused by different reflective arc surfaces 311 mixes with each other, further improving the uniformity.

[0100] Specifically, refer to Figure 2 、 Figure 4 As shown, the height direction is the up-down direction, the thickness direction is the left-right direction, the multiple reflective arc surfaces 311 extend along the up-down direction, and the multiple reflective arc surfaces 311 are sequentially arranged in the left-right direction to further mix the light.

[0101] It should be noted that the diffusion of light by the reflective arc surface 311 does not cause the light to be unable to propagate to the first light emitting portion 32. When the reflective arc surface 311 guides the light to the front, it causes the light to tilt in the left and right directions, so that the light can both propagate to the first light emitting portion 32 and be mixed.

[0102] In some specific embodiments, a protrusion is provided on the first light guiding portion 31, which protrudes in a direction away from the first light emitting portion 32, and the inner surface of the protrusion facing the first light emitting portion 32 is constructed as a reflective arc surface 311, which reduces the processing difficulty of the light transmitting component 30 and facilitates the molding of the light transmitting component 30.

[0103] Specifically, the raised portion is raised in a direction away from the first light exit portion 32 , that is, the raised portion is raised toward the rear, and light propagates inside the light-transmitting member 30 . The inner surface of the raised portion is configured as a reflective arc surface 311 .

[0104] In other specific embodiments, a groove is provided on the first light guiding portion 31, which is recessed toward the first light emitting portion 32, and the inner surface of the groove facing the first light emitting portion 32 is constructed as a reflective arc surface 311, which reduces the processing difficulty of the light transmitting component 30 and facilitates the molding of the light transmitting component 30.

[0105] Specifically, the groove is recessed in a direction away from the first light-emitting portion 32, that is, the convex portion is recessed forward. Light travels inside the light-transmitting member 30, and the inner surface of the groove is configured as a reflective arc surface 311.

[0106] More specifically, the reflective arc surface 311 is configured as a total reflection surface, guiding as much light as possible to the first light-emitting portion 32 and reducing light loss.

[0107] It should be noted that the total reflection surface is a surface for achieving total reflection. When light irradiates on the reflective arc surface 311, total reflection occurs, there is no refracted light on the reflective arc surface 311, and all the incident light is reflected on the reflective arc surface 311.

[0108] According to some other embodiments of the present invention, the first light-emitting portion 32 includes a plurality of light-emitting curved surfaces 321. The light-emitting curved surfaces 321 protrude in a direction away from the first light-guiding portion 31, and the plurality of light-emitting curved surfaces 321 are arranged in an array.

[0109] In the above solution, by providing the light-emitting curved surfaces 321, the shape of the light-emitting curved surfaces 321 is used to diffuse light, so that the light is diffused and emitted, making the light softer and having a better visual effect when the human eye observes the first light-emitting portion 32. Further, the plurality of light-emitting curved surfaces 321 are arranged in an array, that is, the plurality of light-emitting curved surfaces 321 are neatly arranged, diffusing the light reflected by the first light-guiding portion 31 and further improving the optical effect.

[0110] Among them, the light-emitting curved surfaces 321 protrude in a direction away from the first light-guiding portion 31. The first light-emitting portion 32 is located in front of the first light-guiding portion 31. The light-emitting curved surfaces 321 protrude in a direction away from the first light-guiding portion 31, that is, the light-emitting curved surfaces 321 protrude forward.

[0111] Specifically, referring to Figure 3 、 Figure 6 As shown, the plurality of light-emitting curved surfaces 321 are configured as corn kernel patterns, and the form of the corn kernel patterns has a lower cost and is convenient for manufacturing.

[0112] According to still some other embodiments of the present invention, the first light-guiding portion 31 includes a plurality of reflective arc surfaces 311. The reflective arc surfaces 311 extend in the height direction, and the plurality of reflective arc surfaces 311 are sequentially arranged in the thickness direction of the light homogenizing member 20. At the same time, the first light-emitting portion 32 includes a plurality of light-emitting curved surfaces 321. The light-emitting curved surfaces 321 protrude in a direction away from the first light-guiding portion 31, and the plurality of light-emitting curved surfaces 321 are arranged in an array.

[0113] In the above solution, while providing a plurality of reflective arc surfaces 311, a plurality of light-emitting curved surfaces 321 are provided. While using the curved surface of the reflective arc surface 311 to diffuse light in the thickness direction, the shape of the light-emitting curved surfaces 321 is used to diffuse light, making the overall effect of the optical component 100 better.

[0114] Specifically, in the above solution, a plurality of reflective arc surfaces 311 extend in the height direction. The arc-shaped surface causes the light to spread in the thickness direction. Refer to Figure 2 、 Figure 4 As shown, the arc-shaped surface causes the light to spread in the left and right directions, and a plurality of reflective arc surfaces 311 are sequentially arranged in the thickness direction of the light homogenizing member 20. The light diffused by different reflective arc surfaces 311 is mixed with each other, further improving the uniformity.

[0115] Among them, refer to Figure 2 、 Figure 4 As shown, the height direction is the up and down direction, the thickness direction is the left and right direction. A plurality of reflective arc surfaces 311 extend in the up and down direction, and a plurality of reflective arc surfaces 311 are sequentially arranged in the left and right direction, further mixing the light.

[0116] It should be noted that the diffusion of light by the reflective arc surface 311 will not cause the situation that the light cannot propagate to the first light-emitting part 32. When the reflective arc surface 311 guides the light forward, the light is inclined in the left and right directions, so that the light can not only propagate to the first light-emitting part 32 but also be mixed.

[0117] In some specific embodiments, a convex portion is provided on the first light guide portion 31. The convex portion protrudes in a direction away from the first light-emitting part 32. The inner surface of the convex portion facing the first light-emitting part 32 is configured as a reflective arc surface 311, reducing the processing difficulty of the light-transmitting member 30 and facilitating the molding of the light-transmitting member 30.

[0118] Specifically, the convex portion protrudes in a direction away from the first light-emitting part 32, that is, the convex portion protrudes backward. The light propagates inside the light-transmitting member 30, and the inner surface of the convex portion is configured as a reflective arc surface 311.

[0119] In some other specific embodiments, a groove is provided on the first light guide portion 31. The groove is recessed in a direction facing the first light-emitting part 32. The inner surface of the groove facing the first light-emitting part 32 is configured as a reflective arc surface 311, reducing the processing difficulty of the light-transmitting member 30 and facilitating the molding of the light-transmitting member 30.

[0120] Specifically, the groove is recessed in a direction away from the first light-emitting part 32, that is, the convex portion is recessed forward. The light propagates inside the light-transmitting member 30, and the inner surface of the groove is configured as a reflective arc surface 311.

[0121] More specifically, the reflective arc surface 311 is configured as a total reflection surface, guiding as much light as possible to the first light-emitting part 32 and reducing the loss of light.

[0122] In the above solution, by providing the light-emitting surface 321, the shape of the light-emitting surface 321 is used to diffuse the light, so that the light is diffusely emitted, making the light softer and providing a better visual effect when the human eye observes the first light-emitting part 32. Further, a plurality of light-emitting surfaces 321 are arranged in an array, that is, a plurality of light-emitting surfaces 321 are neatly arranged, diffusing the light reflected by the first light guide part 31 and further improving the optical effect.

[0123] Among them, the light-emitting surface 321 protrudes in a direction away from the first light guide part 31. The first light-emitting part 32 is located in front of the first light guide part 31. The light-emitting surface 321 protrudes in a direction away from the first light guide part 31, that is, the light-emitting surface 321 protrudes forward.

[0124] Specifically, a plurality of light-emitting surfaces 321 form a corn kernel pattern, and the form of the corn kernel pattern has a lower cost and is convenient for manufacturing.

[0128] The following will Figures 1 to 6 , describe in detail the optical component 100 of the embodiment of the present invention.

[0129] The optical component 100 includes: a light-emitting member 10, a light homogenizing member 20, and a light-transmitting member 30.

[0130] The light-emitting member 10 is an LED particle. There are four light-emitting members 10, and the four light-emitting members 10 are arranged at intervals in the left-right direction. The light-emitting member 10 is used to emit light.

[0131] The light homogenizing member 20 is a light guide plate. The light homogenizing member 20 is arranged in front of the light-emitting member 10. The light homogenizing member 20 includes: a light homogenizing part 21 and a second light guide part 22.

[0132] In the up-down direction, the light homogenizing part 21 coincides with the light-emitting member 10 to receive and homogenize the light. The length of the light homogenizing part 21 is 20 mm.

There are a plurality of the second tooth parts 2232, and the distance between two adjacent second tooth parts 2232 is T2, and T1>T2.

[0134] Wherein, the side surface of the tooth part 223 is configured as a first reflecting surface. The lower side of the second light guide part 22 is configured as a second light emitting part 222, and the first reflecting surface guides light to the second light emitting part 222.

[0135] The light transmissive member 30 is arranged below the light homogenizing member 20. The light transmissive member 30 has a first side surface 33, a second side surface 34 and a third side surface 35. The first side surface 33 and the second side surface 34 are oppositely arranged, and the third side surface 35 is adjacent to the first side surface 33 and the second side surface 34 respectively.

The first light guide part 31 realizes total reflection. The light transmissive member 30 is used for left and right diffusion through the reflecting arc surfaces 311. Finally, the light is diffusely emitted for the second time through the light emitting curved surfaces 321 in front of the light transmissive member 30.

[0138] Wherein, the length of the light homogenizing member 20 is 20 mm and is used for light mixing.
