  "textContent": "A lighting device includes a light-condensing device (6) having annular portions of a substantially semi-circular section, formed on a periphery of a convex lens (7), in which the light-condensing device (6) is disposed in a state that a light-incoming plane (7a) of the convex lens (7) and first inner wall surfaces (8a) of the annular portions (8) are made to face a light source (lamp) (9). And, lights from the light source (9) falling on the light-condensing device (6) are set to efficiently travel from the light-outgoing plane (5a) of the convex lens (7) and second inner wall surfaces of the annular portions toward a small specific area such as a light-incoming end surface of a light-guiding device (5). Thereby, the lights from the light source can effectively be used for lighting.",
