Abstract
The present invention provides a light guide structure for a light sensor. The light sensor is used to sense ambient light incident on an opening of a decorative plate of an electronic device. The light guide structure includes a light guide plate. The light guide plate has an outer surface and an inner surface, and a part of the light guide plate protrudes from the outer surface toward the opening to form a light guide portion. The light guide portion has a light incident surface and a light emitting surface. The light incident surface is located outside the opening, and the light emitting surface is arranged opposite to the light sensor.
