Mobile terminal having guiding member for guiding a direction of visible light emitted from a light source

A mobile terminal for performing visible light communication using visible light emitted from a light source, which is turned on/off according to a predetermined condition, the mobile terminal comprising:

• a light receiving unit configured to receive visible light;
• and
• a controller configured to extract data corresponding to QN/QFF of the light source from the received visible light,
• wherein the light receiving unit comprises at least one of an illumination sensor, a first image sensor disposed on a front surface of the mobile terminal, or a second image sensor disposed on a rear surface of the mobile terminal,
• wherein the light receiving unit further comprises a guide member for guiding a direction of the visible light emitted from the light source,
• wherein the illumination sensor comprises a plurality of photodiodes,
• wherein the guide member comprises a penetration hole corresponding to each of the plurality of photodiodes, and
• wherein the guide member comprises a plurality of layered sheets, and wherein a convex lens unit is formed on a surface of each of the sheets.
