Abstract

An illumination device includes a housing, an electrical connector, a light source and an elongated light guiding member. The electrical connector is disposed on the housing. The electrical connector has a first terminal contact for electrical connection to a power supply port of a portable electronic device, and a second terminal contact. The light source is electrically connected with the second terminal contact and configured for emitting light. The elongated light guiding member has a light incident surface at a distal end. The light incident surface faces the light source for receiving the light from the light source. The elongated light guiding member is configured for matingly contacting a peripheral side surface of the portable electronic device. The elongated light guiding member has a light emitting surface for emitting the light therefrom.
