In the technical solution of the present invention, a scattering area 21 is disposed on the light emitting surface 20 of the light guide 100, and a scattering structure 211 is disposed on the scattering area 21. Thus, when the electronic device 1000 operates, light emitted by the plurality of light sources 410 on the lamp panel 400 enters the light guide member 100 through the light incident surface 10, the light is emitted through the light emergent surface 20 after being subjected to light guide processing in the light guide member 100, because the light emergent surface 20 is provided with the scattering region 21, and the scattering structure 211 is arranged in the scattering region 21, the scattering structure 211 can reflect the light passing through the scattering region 21 for multiple times, so that the light passing through the scattering region 21 can be uniformly dispersed to each position of the scattering region 21, so that the scattering region 21 can uniformly emit the light out of the housing 200 of the electronic device 1000, the uniformity of the light emitted by the electronic device 1000 can be improved under the condition that the light mixing distance of the electronic device 1000 is not changed, bright and dark light spots are weakened, and the light emitting effect of the electronic device 1000 is improved. That is, the uniformity of the light emitted from the electronic device can be improved without changing the thickness of the electronic device 1000, and the requirement of the light design of the product is met.
It should be noted that the lamp panel 400 may be an annular lamp panel 400, or may also be a square lamp panel 400 or a lamp panel 400 with other shapes, and the shape of the lamp panel 400 is reasonably set according to the specific shape of the product, which is not limited herein. It can be understood that the plurality of light sources 410 are arranged in an array on the lamp panel 400, such that the distance between two light sources 410 is equal, and thus, the uniformity of the light emitted from the housing 200 can be improved over the light sources.

Referring to fig. 1, 2 and 4, in an embodiment of the invention, the scattering region 21 is disposed above the light source 410.
In the technical solution of an embodiment of the present invention, since the light incident surface 10 of the light guide 100 faces the surface of the lamp panel 400 on which the light source 410 is disposed, that is, the light source 410 also faces the light incident surface 10 of the light guide body, light emitted from the light source 410 is guided into the light guide 100 through the light incident surface 10, and most of the light is emitted through the light source 410 after the light is deflected in the light guide 100. Since the center of the light source 410 is the light center, the light intensity value of the light center is high, that is, the light density of the light guide member 100 above the light center of the light source 410 is high, the scattering area 21 is disposed above the light center of the light source 410, so as to scatter more light, thereby increasing the light scattering efficiency and making the light emitted uniformly.
Referring to fig. 5, in an embodiment of the present invention, the scattering structure 211 includes a plurality of convex hulls (not labeled), the convex hulls are arranged in an array in the scattering region 21, and edges of two adjacent convex hulls are at least partially connected to each other.
In the technical solution of an embodiment of the present invention, each convex hull is a single body of the scattering structure 211. A plurality of convex hulls are arranged in an array, and at least parts of the edges of two adjacent convex hulls are connected with each other. That is, the overlapping area of the convex hulls is about one tenth of the area of a single convex hull, so that the convex hulls can be uniformly and neatly distributed in the whole scattering area 21, and the light passing through the scattering area 21 is ensured to be subjected to the scattering treatment of the convex hulls, so as to improve the scattering rate of the light. Understandably, the scattering regions 21 are fully distributed with a plurality of convex hull arrays, and the adjacent convex hull edges are mutually overlapped, so that the scattering structure 211 of the whole scattering region 21 is formed into a scale structure, which not only can improve the uniformity of light emission, but also has better ornamental performance.
Furthermore, the surface of each convex hull is the arcwall face setting to, the cross section of each convex hull reduces gradually from going out plain noodles 20 to the direction of going back from going out plain noodles 20, so, can increase the scattering angle of light, a plurality of convex hull array settings can make light form reflection many times between a plurality of scattering monomer, further improves the homogeneity of light-emitting. It should be noted that the thickness value of each convex hull ranges from 0.2mm to 0.5mm, and specifically, the thickness values of the convex hulls may be 0.2mm, 025mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, and the like, so that the requirement of scattering light can be ensured, and the purpose of uniform light emission can be achieved.
Still further, the convex hull in the projection of going out the plain noodles 20 is regular hexagon, so, can be so that the convex hull has regular shape, the range of being convenient for, can promote the homogeneity of package, improves the homogeneity of light-emitting, simultaneously, can also make the outward appearance that has rich in aesthetic feeling of leaded light spare 100, promotes the ornamental of product.
Further, can also be at the play plain noodles 20 spraying pearly-lustre oil of leaded light spare 100 for play plain noodles 20 is formed with the pearly-lustre oil layer, so, can make the whole play plain noodles 20 of leaded light spare 100 have the high rate of refraction surface, makes light produce the total reflection more easily, so, light can carry out many times of refractions, further improves the homogeneity of light-emitting, reduces the granular sensation that the light and shade facula that a plurality of lamp pearls produced came, promotes the light-emitting effect of product.
Referring to fig. 3 to 6, in an embodiment of the present invention, the light incident surface 10 of the light guiding main body is provided with a light equalizing structure, and the light equalizing structure is disposed between two adjacent light sources 410.
In the technical solution of an embodiment of the present invention, since the intensities of the light emitted from the light source 410 at different positions are different, the intensity of the light at the optical center is the highest, and the intensity of the light is weaker the farther away from the optical center. When the light guide bodies have a uniform thickness, the transmittance increases as the light intensity value increases, and thus the transmittance decreases as the light intensity value decreases. Thus, light spots with uneven brightness appear outside the housing 200, and the granular feeling of the product is strong. Therefore, through the light equalizing structure arranged between the two adjacent light sources 410, the light equalizing structure can adjust the thickness of the light guide member 100 by taking the difference of the light intensity emitted from different positions of the light source as a reference, so that the transmittance of each position of the light guide member 100 is the same, the generation of light spots with uneven brightness caused by different transmittances of the product is reduced, the granular sensation of the product is weakened, and the optical design effect of the product is improved. Wherein, the structure of light of homonymy can be the groove structure or the lug structure that the income plain noodles 10 of leaded light spare 100 was formed to make the thickness of leaded light spare can adapt to the different intensity in lamp source, behind the leaded light spare of different thickness, the luminous flux that obtains equals, equals in order to reach the transmissivity, and then in order to reach even effect can, does not prescribe a limit to here.
Referring to fig. 3 to 6, in an embodiment of the present invention, each of the light sources 410 is provided with an optical center, a central axis between the optical centers of two adjacent light sources 410 is a symmetric center, and the thickness of the light guiding body decreases from the optical center to the symmetric center; and/or
The light-equalizing structure is an arc-shaped groove structure 11, and the adjacent arc-shaped groove structures 11 form a continuous wave-shaped structure.
In the technical solution of an embodiment of the present invention, the light incident surface 10 of the light equalizing structure is disposed between two adjacent light sources. And, this even light structure still uses the axis between the optical centers of two adjacent light sources as the symmetry center symmetry setting, so for the thickness of leaded light main part is decreased progressively from the optical center to the symmetry center to make different light intensity can evenly must pass the leaded light main part. Further, in an embodiment of the present invention, the light-equalizing structure is formed as an arc-shaped groove structure 11, and adjacent arc-shaped groove structures 11 form a continuous wave-shaped structure. Therefore, the thickness of the light guide main body can be uniformly and smoothly transited from the position with the thickest thickness to the position with the thinnest thickness, so that the light homogenizing effect is better. In particular, the profile of the arcuate slot structure 11 between a plurality of adjacent optical centers is also formed as a continuous and regular sin curve. The light center of the light source 410 is penetrated through the thickest position of the thickness of the light guide main body, and the weakest light of the light source 410 is penetrated through the thinnest position of the thickness of the light guide part 100, so that the passing rate area of the light guide main body is the same, the light spots with uneven brightness are reduced, the granular sensation of the product is weakened, and the optical design effect of the product is improved.
It should be noted that the principle that the contour of the arc-shaped groove structure 11 between a plurality of adjacent optical centers is also formed as a continuous and regular sin curve is as follows: light guide member 100 sets up in the top of lamp plate 400, and lamp source 410 on lamp plate 400 is LED lamp pearl, because of LED lamp pearl is approximate lambert light source, and light distributes evenly to LED lamp top is the benchmark light intensity I that modelsθ＝I0 Cos(θ)The transmittance is inversely proportional to the thickness of the light guide 100, and assuming that the scale factor is K, the light intensity after passing through the light guide 100 is: i is(PC)＝I0 Cos(θ)*KIt is clear that the light intensity gradually decays from the center to the periphery. Referring to fig. 7, in order to make the overall light intensity uniformly distributed, the scale factor K may be simplified to be a Sin curve, so that the overall light intensity passing through the light guide 100 becomes uniform, and the generation of bright and dark spots of the light guide 100 is reduced.
In an embodiment of the invention, the material of the light guide 100 includes a transparent substrate and titanium dioxide uniformly attached to the surface of the transparent substrate, the mass ratio of the titanium dioxide to the substrate is defined as Q, and Q is greater than or equal to 0.015 and less than or equal to 0.025.
In an embodiment of the invention, a substrate of the light guide 100 is a transparent plastic with good light transmittance, for example, the substrate may be polymethyl methacrylate (PMMA), Polystyrene (PS), Polycarbonate (PC), or the like, which is not listed herein. Wherein, the titanium dioxide can be uniformly attached to the surface of the light-transmitting substrate in the injection molding process of the light guide part. Through increasing titanium white powder in light guide 100, can reduce the transmissivity of light guide 100 at each position light on the whole, so, can reduce the intensity of the light through light guide 100 for light through light guide 100 becomes soft, even do not have the light through scattering structure 211 scattering, the dazzling condition can not appear yet. Therefore, the titanium dioxide with a certain mass ratio is added into the light guide member 100, so that glare can be effectively avoided. Specifically, the ratio of the mass of the added titanium dioxide to the mass of the transparent substrate may be 0.015, 0.020, 0.025, or the like. Wherein, when the mass ratio of titanium white powder is 0.020, the transmissivity of leaded light main part reduces to below 50%, so, can satisfy the requirement in the luminance of product, can make the light of product become soft again, prevents that leaded light spare 100 from producing the dazzling condition in non-scattering area 21, improves the optical design requirement of product.
In an embodiment of the invention, the light incident surface 10 is provided with a pattern-drying structure formed by pattern-drying treatment; and/or the surface of the light guide member 100 is provided with a pearlescent oil layer.

The light guide cover 300 also has a light incident surface and a light emitting surface, wherein the light incident surface of the light guide cover is disposed toward the light emitting surface 21 of the light guide 100. The light incident surface of the light guide cover 300 is sprayed with pearlescent oil, so that the light guide cover 300 can further improve the light-homogenizing effect. The light guide cover 300 converges the light processed by the light guide 100, so that the electronic device 1000 can obtain light with proper brightness, uniform light intensity, uniform brightness and no obvious granular sensation, and the grade and the aesthetic feeling of the optical design of the electronic device 1000 are improved. Meanwhile, the light guide 100 is disposed to avoid the glare problem caused by directly seeing the light source from the grating of the light guide cover 300.
