The second body is pivotally connected to the first body. The light module is adjacent to the second body and is disposed on the first body. The light module includes a frame, a light guide plate, a light source, a patterned light guide film, and a light-transmitting cover plate. The frame is disposed on the first body. The light guide plate is disposed in the frame and has a light incident surface and a light emitting surface. The light source is disposed in the frame as corresponding to the light incident surface of the light guide plate. The patterned light guide film is detachably disposed on the light guide plate and covers the light emitting surface. The light-transmitting cover plate is detachably disposed on the frame and covers the patterned light guide film. ## Claims ### Claim 1 A portable electronic device, comprising: a first body; a second body pivotally connected to the first body; and a light module adjacent to the second body and disposed on the first body, wherein the light module comprises: a frame disposed on the first body; a light guide plate detachably disposed in the frame and having a light incident surface and a patterned light emitting surface; a light source disposed in the frame as corresponding to the light incident surface of the light guide plate and; and a light-transmitting cover plate detachably disposed on the frame and covering the patterned light emitting surface. ### Claim 2 A portable electronic device, comprising: a first body; a second body pivotally connected to the first body; and a light module adjacent to the second body and disposed on the first body, wherein the light module comprises: a frame disposed on the first body; a light guide plate disposed in the frame and having a light incident surface and a light emitting surface; a light source disposed in the frame as corresponding to the light incident surface of the light guide plate; a patterned light guide film detachably disposed on the light guide plate and covering the light emitting surface of the light guide plate; and a light-transmitting cover plate detachably disposed on the frame and covering the patterned light guide film, wherein the light-transmitting cover plate has a first magnetic part, the frame has a second magnetic part, and the first magnetic part is magnetically attracted to the second magnetic part. ### Claim 3 (depends on 2) The portable electronic device according to claim 2, wherein the second body has a movable end and a pivot end opposite to each other, the pivot end is pivotally connected to the first body, and the light module is adjacent to the pivot end. ### Claim 4 (depends on 2) The portable electronic device according to claim 2, wherein the first magnetic part and the second magnetic part are a combination of two magnets or a combination of a magnet and a magnetic conductive member. ### Claim 5 (depends on 2) The portable electronic device according to claim 2, wherein the light module further comprises: a circuit board disposed in the frame, wherein the light source and the light guide plate are disposed on the circuit board, and the light source is electrically connected to the circuit board. ### Claim 6 (depends on 5) The portable electronic device according to claim 5, wherein the light source comprises a plurality of light emitting components, a part of the plurality of light emitting components are arranged on the circuit board along a first direction, and a part of the light emitting components are arranged on the circuit board along a second direction perpendicular to the first direction. ### Claim 7 (depends on 5) The portable electronic device according to claim 5, wherein the frame has a positioning hook positioned around the light guide plate, the circuit board has a positioning hole positioned around the light guide plate, and the positioning hook engages with the positioning hole. ### Claim 8 (depends on 5) The portable electronic device according to claim 5, wherein the frame has a positioning hook positioned around the light guide plate, the circuit board has a positioning hole positioned around the light guide plate, the patterned light guide film has a lower surface facing the light emitting surface of the light guide plate and an upper surface opposite to the lower surface, and the positioning hook passes through the positioning hole and contacts the upper surface of the patterned light guide film. ### Claim 9 (depends on 2) The portable electronic device according to claim 2, wherein the frame is divided into a lighting area and a display area adjacent to the lighting area, the lighting area is defined by a range where the patterned light guide film is positioned, the light module further comprises an auxiliary display, and the auxiliary display is disposed in the display area of the frame.
