Referring to fig. 1 and fig. 2, the present application provides an electronic device 1000, where the electronic device 1000 may be a handheld motion device such as an unmanned aerial vehicle or a handheld cradle head, and may also be a communication device such as a smart phone and a personal digital assistant. The electronic device 1000 includes: the light emitting module comprises an equipment shell 100 and a light emitting module 200 arranged in the equipment shell 100, wherein a light outlet 1001 is arranged on the equipment shell 100, and the light emitting module 200 comprises a light source 10 and a light guide device 20;

the light guide device 20 includes a light guide column 21, the light guide column 21 is fixed relative to the light source 10, the light guide column 21 includes a light incident surface 201, a reflecting surface 202 and a light emitting surface 203, the light incident surface 201 is located on one side of the light guide column 21 and is opposite to the light source 10; the light-emitting surface 203 is located on the other adjacent side of the light guide column 21 and is opposite to the light-emitting port 1001; the reflection surface 202 is obliquely disposed opposite to the light incident surface 201 and the light emitting surface 203,

wherein, the reflecting surface 202 is an arc convex surface and is formed by the concave of the light guide column 21;

the light emitted from the light source 10 enters the light guide rod 21 through the light incident surface 201, changes direction after being reflected by the reflecting surface 202, leaves the light guide rod 21 through the light emitting surface 203, and exits from the light exit port 1001.

The electronic device 1000 provided by the present application, by providing the reflecting surface 202 in the arc convex shape, the light emitted by the light source 10 reaches the reflecting surface 202, changes the direction and obtains a larger light emitting angle, and emits to the light emitting surface 203 in a divergent manner, so that the design requirement of the light emitting angle in the direction lateral to the light source 10 irradiation direction can be realized in a smaller space, and the electronic device has a larger external indication light emitting area and a better light emitting effect.

Specifically, the material of the light guide column 21 includes one or more of acrylonitrile-butadiene-styrene copolymer, polycarbonate, and polymethyl methacrylate, and the light guide column 21 made of the above materials has good light guide characteristics. In addition, the light source 10 can be embedded into the light incident surface 201 of the light guide column 21 to ensure that most of the light source 10 can be captured by the light guide column 21, and a convex lens can be arranged between the light source 10 and the light incident surface 201 of the light guide column 21 to focus the light to the light incident surface 201, so that the light capturing rate of the light guide column 21 is improved. The light incident surface 201 faces the light emitting surface of the light source 10. The Light source 10 is an LED (Light Emitting Diode), preferably a surface mount LED, and the Light guide column 21 provided in the present application cooperates with the surface mount LED having a flat structure to further compress the internal structure of the electronic device 1000, which is beneficial to meeting the compact design requirement of the electronic device 1000. A diffusing agent or toner may be added to the light guide 21 to make the emitted light uniformly distributed.

In one embodiment, referring to fig. 2, the light guiding pillar 21 further includes a first surface 204, a second surface 205, a third surface 206 and a fourth surface 207, the light incident surface 201, the first surface 204, the second surface 205, the light emitting surface 203, the third surface 206, the reflecting surface 202 and the fourth surface 207 are sequentially connected, and one side of the fourth surface 207, which is far away from the reflecting surface 202, is connected to the light incident surface 201. The first surface 204, the second surface 205, the third surface 206, and the fourth surface 207 are all flat surfaces, and the light incident surface 201 may be a flat surface or a concave surface formed by a depression. The light emitting surface 203 is preferably a plane, and the light emitting surface 203 is spaced apart from the light outlet 1001. The second surface 205 is parallel to the light incident surface 201 and is located on a side of the light incident surface 201 away from the reflection surface 202, and an included angle α between the first surface 204 and the light incident surface 201 is 60 ° to 120 °. It is understood that the reflecting surface 202 is an arc-shaped convex surface and is formed by the light guide pillar 21 being concave, and the convex surface is opposite to the light ray, and similarly, the light incident surface 201 can be a concave surface formed by the concave surface, and the concave surface is also opposite to the light ray. By arranging the third surface 206 between the light-emitting surface 203 and the reflecting surface 202, the situation that the light-emitting surface 203 and the reflecting surface 202 form a sharp corner and the sharp corner is easily damaged is avoided, and the fourth surface 207 has the same principle. The first surface 204 and the second surface 205 are disposed between the light incident surface 201 and the light emitting surface 203, and the second surface 205 is parallel to the light incident surface 201 and is located on a side of the light incident surface 201 away from the light reflecting surface 202, so that the area of the light emitting surface 203 is increased, and the area of the external indication light is further increased.

The light guide pillar 21 has a triangular prism shape as a whole. It can be understood that, when a plurality of light sources 10 are provided, the light of the light source 10 may escape to the light guide bars 21 corresponding to other light sources 10, so that other light guide bars 21 may guide out wrong light. For example, if the first light source is guiding out red light through the second light guide column, the red light indicates a first function fault, and the second light source has no light guide, it indicates that the second function is not activated, but the red light enters the second light guide column corresponding to the second light source due to dissipation in the second light guide column, so that the second light guide column also guides out the red light, and thus the user easily misjudges that the second function is in a fault state.

In one embodiment, referring to fig. 2, an included angle α between the light incident surface 201 and the light emitting surface 203 is an obtuse angle. Specifically, the value of the included angle α may be 90 °, 95 °, 120 °, 135 °, 160 °, and the like. By setting the included angle α between the light incident surface 201 and the light emitting surface 203 to be an obtuse angle, the light guide pillar 21 has a light emitting angle lateral to the irradiation direction of the light source 10, and meanwhile, the light emitting surface 203 is inclined to the light incident surface 201, so that a larger external indication light emitting area is provided.

In one embodiment, referring to fig. 2, the roughness of the light incident surface 201 is less than the roughness of the light emitting surface 203. It will be appreciated that the smaller the roughness, the smoother the surface, the less diffuse reflection that occurs, and the less light loss, and therefore the lower the roughness of the input surface 201 to ensure that the intensity of the emitted light is sufficient. The larger the roughness, the more irregular the surface, the more diffuse reflection is generated, and the more uniform the light distribution, so the higher roughness is adopted by the light-emitting surface 203 to ensure the uniform distribution of the emitted light.

In one embodiment, referring to fig. 2, the light incident surface 201 is polished, and the light emitting surface 203 has a texture structure. Specifically, the light emitting surface 203 may have a texture structure by means of a spark pattern.
