Abstract
An illuminated key structure and electronic device with the key structure includes a substrate, a light guiding element, a key body, a first reflection film, and a second reflection film. The substrate has a light emitting element disposed on a substrate surface thereof. The light guiding element includes a main body and a light guiding portion. The main body has a first and second surfaces. The light guiding portion is on the first surface and forms, together with the first surface cooperatively, a receiving space for receiving the key body. The first reflective film is disposed on the second surface, and the second reflective film is disposed on the substrate surface. Light from the light emitting element is repeatedly reflected between the first reflection film and the second reflection film before being transmitted out of the key structure through the light guiding portion.
