In addition, although the light guide member of the indicator lamp of some products has a large light transmission area, the light transmission intensity of different areas is different, thereby causing uneven display. Therefore, the indicating effect of the indicating lamp of the existing electronic product is not good enough.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, the present invention provides an electronic product 10 and an indicator light guide 100. The electronic product 10 includes an indicator light guide 100, a housing 200, and a circuit board 300.

The electronic product 10 may be a mobile power supply, a charger, or the like. The housing 200 is formed with a light hole (not shown), and the circuit board 300 is received and fixed in the housing 200. The circuit board 300 is provided with an indicator lamp 310, and light emitted by the indicator lamp 310 can be guided out from the light-transmitting hole through the indicator lamp light-guiding member 100, so that indication is realized.

Referring to fig. 2, the light guide member 100 of the indicating lamp in the preferred embodiment of the present invention includes a light transmissive main body 110, an incident surface 120 and a light emitting surface 130.

The light-transmitting body 110 is made of a light-transmitting material, and may be glass, resin, plastic, or the like. The light may pass through the light-transmitting body 110 and be refracted. The light-transmitting body 110 has a plate shape, and the shape thereof may be designed according to the shape of the light-transmitting hole.

The incident surface 120 and the light emitting surface 130 are respectively located at two opposite sides of the light transmissive body 110. Specifically, the incident surface 120 and the light emitting surface 130 may be formed on the light transmissive body 110 by polishing and cutting. In the electronic product 10, the indicator 310 is disposed opposite to the incident surface 120, and the light emitting surface 130 is located in the light-transmitting hole. The light of the indicator 310 is incident through the incident surface 120, refracted through the light-transmitting body 110, and then emitted through the light-emitting surface 130. To avoid glare, in the embodiment, the light emitting surface 130 is a plane.

In the embodiment, a boss 111 is formed on a side of the light transmissive body 110 facing away from the incident surface 120, and the light emitting surface 130 is located on a surface of the boss 111. The shape of the boss 111 matches the contour of the inner wall of the light-transmitting hole. Therefore, the boss 111 can be snapped into the light hole, thereby facilitating the positioning and fixing of the light guide member 100 of the indicator light.

The incident surface 120 is an arc concave surface. Therefore, the light-transmitting body 110 functions as a concave-convex mirror, thereby functioning to disperse light. When the light of the indicator 310 is incident through the incident surface 120, the light is diffused, so as to increase the light emitting range on the light emitting surface 120. In order to make the light emission more uniform, in the present embodiment, the incident surface 120 is a spherical surface.

In the embodiment, the orthographic projection of the light emitting surface 130 on the light transmissive body 110 completely covers the orthographic projection of the incident surface 120 on the light transmissive body 110.

That is, the light emitting surface 130 is larger than the incident surface 120. After the light of the indicator lamp 310 is refracted, the light-emitting angle is increased. Therefore, a larger exit face 130 is beneficial to avoid light energy loss, resulting in better pointing.

Further, a diffuse reflection area 121 is formed on the incident surface 120. In the diffuse reflection area 121 and the rough area on the surface of the incident surface 120, light is incident from the diffuse reflection area 121 and is diffused. The diffuse reflection area 121 may be formed on the incident surface 120 by polishing, film-attaching, silk-screen printing, or the like. Specifically, in the present embodiment, the diffuse reflection area 121 is a frosted area. That is, the diffuse reflection area 121 can be obtained by directly roughening a specific area of the incident surface 120 by polishing. Therefore, the diffuse reflection area 121 can be molded at one time when the incident surface 1210 is molded, so that a separate process is not required.

The light reflected by the diffuse reflection can form a large area of scattered light, and the scattered light can further increase the light emitting area of the light emitting surface 130 after being refracted by the light transmissive main body 110. Moreover, after multiple times of diffuse reflection, the light emitted from each angle is more uniform, so that the light intensity distribution on the light emitting surface 130 is uniform.

In this embodiment, the incident surface 120 is further formed with a light surface area 123, the diffuse reflection area 121 is located in the middle of the incident surface 120, and the light surface areas 123 are located at the edge of the incident surface 120 and distributed along the circumferential direction of the diffuse reflection area 121.

Specifically, the smooth area 123 refers to an area with a smooth surface, and light rays are not diffusely reflected in the smooth area 123. Since the indicator lamp 310 emits light in a spherical shape, the light applied to the edge of the incident surface 120 is inherently weak. At this time, the edge of the incident surface 120 is set as a smooth surface, so that the light energy loss caused by the diffuse reflection of the light incident from the smooth surface area 123 can be effectively avoided, and the uniformity of the emergent light can be further improved.

In the electronic product 10 and the indicator light guide 100 thereof, the light of the indicator light 310 enters the transparent main body 110 through the incident surface 120 and exits through the exit surface 130 for indication. Since the incident surface 120 is an arc concave surface, the light-transmitting body 110 is equivalent to a concave-convex lens, and thus can radiate light to increase the light-emitting range. Furthermore, since the incident surface 120 has the diffuse reflection area 121, the light reflected by diffuse reflection can form a large area of scattered light, and the scattered light can further increase the light emitting area of the light emitting surface 130 after being refracted. After multiple times of diffuse reflection, the emergent light rays from all angles are more uniform. Therefore, after the light emitted by the indicator lamp 310 is reflected and refracted for multiple times, the light-transmitting area on the light-emitting surface 130 is larger and the illumination intensity is more uniform, so that the indicating effect is remarkably improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
