Abstract

An electronic device with light emitting function includes a casing, a circuit board, a light-shielding member, a first light-guiding member, and a second light-guiding member. The casing has a light-guiding cover plate having a first partial block and a second partial block. The circuit board has a light-emitting element adjacent to the first partial block. The light-shielding member is blocked between the light-emitting element and the first partial block. The first light-guiding member has a first reflective inclination surface at a light-emitting direction of the light-emitting element and configured to reflect a light emitted by the light-emitting element to be a first reflected light which is transmitted toward a direction away from the first partial block. The second light-guiding member has a second reflective inclination surface configured to reflect the first reflected light to be a second reflected light which is irradiated to the second partial block.

Claims (15)
