1. A light guide structure for an electronic device comprising:
a housing; an LED; a hollow conical light guide element installed on an inner surface of the housing and having a reflective inner surface and an open end opposite to a pointed end thereof, wherein the LED is provided at the pointed end of the light guide element for generating a light beam and projecting the light beam to the open end along a central axis of the light guide element; an opaque reflective region formed by a part of the housing as a flat plate and corresponding to the central axis, wherein the opaque reflective region does not block the open end completely; and a light-permeable portion formed by a part of the housing as a flat plate and located around the opaque reflective region and outside the central axis, wherein the open end corresponds to the light-permeable portion. |
