Abstract

The invention discloses a marking structure and an electronic device, wherein, the marking structure comprises a box body, a marking hole is arranged on the box body, and a light source and a light guide plate are accommodated in the box body. The light guide plate is accommodated in that box body and exposes the light of the light source at the mark hole, one side of the light guide plate is opposite to the light source, and the light guide plate is protruded toward the side surface of the light source with two protruding parts and a light condensing part. A light condensing section focuses incoming light rays of a light source on a central axis of the light guide plate, a plurality of tooth-shaped protrusions are protruded toward the surface of the light source, two protrusions are respectively located on opposite sides of the light condensing portion, and the protrusions include an incident surface and a total reflection surface, the incident surface faces the light condensing portion, and the total reflection surface faces away from the light condensing portion. The marking structure provided by the invention improves the utilization rate of light energy, improves the light intensity and uniformity of the light guide plate, improves the user experience, and further reduces the cost.

Description

technical field [0001] The invention relates to the technical field of product identification, in particular to an identification structure and an electronic device containing the identification structure. Background technique [0002] LOGO (logo) is an essential part of audio, TV and other electronic products. As users have higher and higher requirements for product logos, many product logos begin to use luminous effects to enhance the appearance and visual experience of products. The existing sign structure usually adopts a side-type backlight structure, and the light source of the side-type light guide plate mostly uses a lamp tube or a light-emitting diode, and the light emitted by the lamp tube or light-emitting diode is incident on the side of the light guide plate, so the brightness of the light guide plate It will decrease with the increase of the lateral distance from the light-emitting element, and the efficiency of light use is not high. As a result, the logo stru...
