Abstract: A light guide element is adapted to be used in an electronic device including a light emitting unit that has at least one light emitting element. The light guide element includes a base portion and a plurality of light guide bodies. The base portion includes a light entry surface for incidence of light emitted by the light emitting unit and at least one side surface connected to the light entry surface. The light guide bodies are disposed on the at least one side surface. Each of the light guide bodies is formed with at least three light exit surfaces. Each of the light exit surfaces has an extension direction. The extension direction and the at least one side surface of the base portion form therebetween an angle being between 10° and 85°.

Abstract: A memory device includes a substrate, a heat dissipation structure and a light guide element. The substrate includes a storage module, plural light-emitting elements and a connection interface. A first connection part and a second connection part of the connection interface are respectively disposed on a first substrate surface and a second substrate surface, located near a first lateral side of the substrate and electrically connected with an electronic device. The heat dissipation structure is partially connected with the substrate. The light guide element is assembled with or locked on the heat dissipation structure, and located near a second lateral side of the substrate. At least one channel is formed between the heat dissipation structure and the substrate. After the light beams of the light-emitting elements pass through the channel, the light beams are centralized or distributed on the light guide element.

Abstract: A light guide device made of a light diffusing agent-free light transmissive material is disclosed to include a base provided with a light-incident surface at one side thereof to face toward the light-emitting side of a plurality of predetermined light-emitting devices, and a plurality of continuously connected and irregularly configured light guide components located on at least one side of the base and capable of unevenly projecting light passing therethrough toward the outside and respectively provided with at least three light-emitting surfaces, each light-emitting surface defining with the base a respective contained angle that causes a glare effect when light passes through the respective the light guide component.
