Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a light guide structure. The light guide structure can conduct external light rays emitted from one end to the other end to be emitted, and is often matched with an LED lamp to form an indicating lamp structure and applied to various electronic devices. The electronic device may be a smart phone, a tablet computer, or other devices, and may also be a game device, an AR (Augmented Reality) device, an automobile device, a data storage device, an audio playing device, a video playing device, a notebook computer, a desktop computing device, or other devices.
Referring to fig. 1, fig. 1 is a first structural schematic diagram of a light guide structure according to an embodiment of the present disclosure. The light guide structure 100 may include a first portion 110, a second portion 120, and a third portion 130. The first portion 110 and the third portion 130 are respectively connected to two ends of the second portion 120 in a bending manner, and the bending direction of the first portion 110 relative to the second portion 120 is opposite to the bending direction of the third portion 130 relative to the second portion 120, so that the light guide structure 100 generally presents a zigzag shape as a whole.
The light guide structure 100 can conduct the external light emitted from the end a of the light guide structure 100 to the end B of the light guide structure 100 for emission. The end surface 111 of the free end of the first portion 110, which is not connected to the second portion 120, serves as a light inlet surface of the light guide structure 100, and is used for receiving external light and emitting the external light into the light guide structure 100; the end surface 131 of the free end of the third portion 130, which is not connected to the second portion 120, serves as a light-emitting surface of the light guide structure 100, and is used for emitting the external light emitted into the light guide structure 100 out of the light guide structure 100.
It should be noted that, in a general electronic device, a light source of the indicator light is a Light Emitting Diode (LED), the LED light is disposed on a circuit board inside the electronic device, and a light outlet of the indicator light is disposed on a housing outside the electronic device, so that the light source and the light outlet are not on a same plane, and a stacked structure exists therein. Therefore, the light guiding structure 100 is arranged in a zigzag shape, so that the light entering surface 111 and the light exiting surface 131 of the light guiding structure 100 are not on the same plane, thereby solving the problem of structural stacking inside the electronic device. It is understood that in other applications, the light guide structure 100 may not be "zigzag" if desired.
Such as: the light guide structure 100 may also be arranged in an "L" shape, so that the light guide structure 100 includes only the first portion 110 and the third portion 130, and the light entering surface 111 and the light exiting surface 131 of the light guide structure 100 are inclined to each other and are not parallel. In some embodiments, the light-entering surface 111 and the light-exiting surface 131 of the light-guiding structure 100 are perpendicular to each other, and the incident light and the exiting light are perpendicular to each other.
For another example: the light guide structure 100 may also be arranged in a "[" shape, and the light guide structure 100 still includes three portions, i.e., a first portion 110, a second portion 120, and a third portion 130, but the bending direction of the first portion 110 with respect to the second portion 120 is the same as the bending direction of the third portion 130 with respect to the second portion 120. The light inlet surface 111 and the light outlet surface 131 of the light guide structure 100 are still parallel to each other, and the incident light and the emergent light are parallel to each other but opposite in direction.
Referring to fig. 2, fig. 2 is a dimension diagram of a light guide structure according to an embodiment of the present disclosure. The first portion 110, the second portion 120, and the third portion 130 may each be a polyhedral structure having a uniform thickness. The thickness of the first portion 110 is p, the thickness of the second portion 120 is q, the thickness of the third portion 130 is n, and p, q, and n are real numbers greater than zero. The thickness of the first portion 110 is greater than the thickness of the third portion 130, i.e., p > n. In some embodiments, the thickness of each of the first portion 110 and the second portion 120 is greater than the thickness of the third portion 130, and the thickness of the first portion 110 is equal to the thickness of the second portion 120, i.e., p q > n. For example, the first portion 110 and the second portion 120 each have a thickness of 1.2mm, and the third portion 130 has a thickness of 0.5 mm.
The light emitting surface 131 on the third portion 130 may be rectangular, and the length-width ratio of the light emitting surface 131 is 20: 1. It is easy to understand that the thickness of the third portion 130 is the width of the light emitting surface 131, i.e. n. Therefore, the width of the light emitting surface 131 is 0.5mm, and the length of the light emitting surface 131 is 10 mm.
It should be noted that, in the embodiment of the present application, the size of the light guide structure 110 is not limited thereto, the first portion 110 and the second portion 120 are polyhedral structures with uniform thickness, and the third portion 130 may be a non-uniform polyhedral structure with thinner and thicker thickness. Wherein the end of the third portion 130 connected to the second portion 120 is thicker than the free end of the third portion 130 not connected to the second portion 120. For example, the thickness of each of the first portion 110 and the second portion 120 is 1.2mm, the thickness of the end of the third portion 130 connected to the second portion 120 is 1.2mm, and the thickness of the free end of the third portion 130 not connected to the second portion 120 is 0.5 mm.
The light guide structure that this application embodiment provided, through setting up "Z" font leaded light post to the terminal surface at leaded light post both ends is regarded as into plain noodles and play plain noodles respectively, and control leaded light post from advancing the plain noodles to going out the plain noodles by the thickness attenuation, can make by advancing the external light that the plain noodles jetted into the leaded light post and spread in the transmission process, thereby reduce the inhomogeneous phenomenon of play plain noodles light-emitting, improve the display effect on plain noodles.
Referring to fig. 1 and fig. 3 together, fig. 3 is a top view of the light guide structure shown in fig. 1. The light inlet surface 111 may be configured as an inner concave surface, and specifically, the light inlet surface 111 may be formed by an end surface of a free end of the first portion 110, which is not connected to the second portion 120, being concave towards the inside of the light guide structure 100. Compared with the light inlet surface 111 being a plane, the concave curved light inlet surface 111 can diffuse the external light entering the first portion 110, so that the light path is wider. As shown in fig. 3, the parallel incident light 160 enters the first portion 110 from the light entrance surface 111, and the concave light entrance surface 111 acts as a concave mirror, so that the light rays 161 entering the first portion 110 are not parallel to each other, but are spread.
Referring to fig. 4, fig. 4 is a schematic view illustrating a second structure of a light guide structure according to an embodiment of the present disclosure. The light guide structure 100 is provided with light guide powder 170 inside, and specifically, a certain amount of light guide powder may be added in the process of forming the light guide structure 100, for example, 4% of light guide powder is added before forming the light guide structure 100. Since the position of the light guiding powder 170 in the light guiding structure 100 is uncertain and there is no regularity, when the light 162 entering the light guiding structure 100 passes through the light guiding powder 170, the light 162 is refracted in a non-directional manner, the direction of the light 163 after being refracted in the non-directional manner is more uncertain, the light path is further diffused, and more areas in the length direction of the light emitting surface 131 have light emission.
It is understood that the adding ratio of the light guide powder 170 in the light guide structure 100 in the embodiment of the present application is not limited thereto, and may be other values, which is not limited by the embodiment of the present application.
Referring to fig. 5, fig. 5 is a partially enlarged view of a portion C in the light guide structure shown in fig. 4. The side surface of the light guide structure 100 is provided with a concave-convex structure so that the side surface of the light guide structure 100 is a rough frosted surface rather than a smooth flat surface. The side surfaces of the light guide structure 100 are all surfaces of the light guide structure 100 except the light inlet surface 111 and the light outlet surface 131. In some embodiments, all surfaces of the light guide structure 100 except the light inlet surface 111 and the light outlet surface 131 may not be frosted, but only the surfaces of the light guide structure 100 parallel to the thickness direction of the first portion 110, the second portion 120, and the third portion 130 may be frosted.
When the light 163 after non-directional refraction is conducted inside the light guide structure 100, a part of the light 164 may be emitted to the side surface of the light guide structure 100, the rough frosted side surface of the light guide structure 100 may perform diffuse reflection on the light 164, and the light 165 after diffuse reflection is emitted to the inside of the light guide structure 110 again, so that the loss of the light 164 on the side surface of the light guide structure 100 may be avoided.
It should be noted that the way in which the side surface of the light guide structure 100 is provided as the frosted surface in the embodiment of the present application is not exclusive. In some embodiments, the side of light guide structure 100 may be provided as a frosted surface by etching. In some embodiments, the side of the light guide structure 100 may also be provided as a frosted surface by means of sandblasting. In some embodiments, the side surfaces of the light guide structure 100 may also be provided as frosted surfaces by means of electron bombardment. The embodiments of the present application do not limit this.
Referring to fig. 1, 3 and 6, fig. 6 is a cross-sectional view of the light guide structure shown in fig. 3 taken along a direction P1-P1. The light guide structure 100 may further include a first connection part 140 and a second connection part 150. The first connection portion 140 is connected between the first portion 110 and the second portion 120, and the second connection portion 150 is connected between the second portion 120 and the third portion 130. The inner surfaces of the first and second connection parts 140 and 150 may be provided as a smooth mirror surface.
When external light enters the first portion 110 from the light entrance surface 111, the light is further transmitted to the first connection portion 140 by the conduction of the first portion 110; the first connecting portion 140 reflects the light emitted to the first connecting portion 140 into the second portion 120, and the light is further emitted to the second connecting portion 150 by the conduction of the second portion 120; the second connecting portion 150 reflects the light emitted to the second connecting portion 150 into the third portion 130, and the light exits the light guide structure 100 from the light exit surface 131 through the transmission of the third portion 130.
It should be noted that, the smaller the included angle ∠ E between the first portion 110 and the first connection portion 140, the smaller the bending angle between the first portion 110 and the second portion 120, and the smaller the included angle ∠ F between the second portion 120 and the second connection portion 150, the smaller the bending angle between the second portion 120 and the third portion 130, the smaller the bending angle between the first portion 110 and the second portion 120 and the bending angle between the second portion 120 and the third portion 130, the closer the overall shape of the light guide structure 100 is to the real letter "Z", and in the light guide structure with such a shape, the light path is folded back, which increases the loss of light during the conduction process and is not beneficial to the conduction of light, therefore, the included angle ∠ E between the first portion 110 and the first connection portion 140 and the included angle ∠ F between the second portion 120 and the second connection portion 150 are not smaller than 135 ° to ensure that the incident angle of the total reflection of light is not larger than 45 ° when the light is conducted in the light guide structure 100.
For example, when an angle ∠ E between the first portion 110 and the first connection portion 140 and an angle ∠ F between the second portion 120 and the second connection portion 150 are both 135 °, an angle of incidence of the two mirror total reflections is 45 °, an angle ∠ E between the first portion 110 and the first connection portion 140 is 135 °, an angle ∠ F between the second portion 120 and the second connection portion 150 is 145 °, angles of incidence of the two mirror total reflections are 45 ° and 35 °, an angle ∠ E between the first portion 110 and the first connection portion 140 is 150 °, an angle ∠ F between the second portion 120 and the second connection portion 150 is 145 °, angles of incidence of the two mirror total reflections are 30 ° and 35 °, in some embodiments, when an angle ∠ E between the first portion 110 and the first connection portion 140 and an angle ∠ F between the second portion 120 and the second connection portion 150 are both 140 °, when light is transmitted in the light guiding structure 100, angles of the two mirror total reflections are both 40 °, an optimal light guiding effect can be achieved.
It is understood that, in the embodiment of the present invention, the degrees of the included angle ∠ E between the first portion 110 and the first connection portion 140 and the included angle ∠ F between the second portion 120 and the second connection portion 150 are not limited to the above examples, and may also be other degrees not less than 135 °, such as 138 °, 157 ° or 169 °, which is not limited by the embodiment of the present invention.
The light guide structure that the embodiment of the application provided, through setting up "Z" font leaded light post, regard as into plain noodles and play plain noodles respectively with the terminal surface at leaded light post both ends, control leaded light post is from advancing the plain noodles to going out the plain noodles by thick attenuation, and through advancing the curved surface that the plain noodles set up to the indent with diffusion incident ray, at the inside leaded light powder that adds of leaded light post with carry out the non-directional refraction to the light of penetrating, and set up the side of leaded light post into rough frosting and carry out diffuse reflection with the light of penetrating, can make by advancing the external light that the plain noodles kicked into light guide structure and spread to whole play plain noodles in the transmission process, thereby reduce the inhomogeneous phenomenon of play plain noodles light, improve the display effect of going out the plain noodles.
