Electronic device and light indicator module thereof

An electronic device comprising:

• a housing, comprising a light-transmitting window, wherein the light-transmitting window is a singular longitudinal opening;
• and
• a light indicator module, disposed in the housing and comprising:
• a circuit board;
• a plurality of light sources, disposed on the circuit board, wherein each of the plurality of light sources provides a light beam;
• a light guide unit, comprising:
• a plurality of guiding blocks, each of the plurality of guiding blocks comprising a light emitting surface, a light entering side surface, and at least one abuttal side surface, and the at least one abuttal side surface facing toward an adjacent one of the plurality of guiding blocks, wherein one of the plurality of light sources corresponds to the light entering side surface, the light beam enters the guiding block through the light entering side surface and is emitted through the light emitting surface before penetrating the light-transmitting window to exit the housing, wherein all of the guiding blocks face to the light-transmitting window;
• and
• a shielding material covering the at least one abuttal side surface, wherein a thickness of the shielding material between two of the at least one abuttal side surface adjacent to one another is more than 0 mm and less than or equal to 0.2 mm.
