摘要： A light guide includes a rod-shaped first light guide portion including a prism surface including a prism to reflect internally propagating light and output the light to an outside along a lengthwise direction thereof, a rod-shaped second light guide portion including a light intake portion to take in light from a light source, and a rod-shaped intermediate light guide portion between the first light guide portion and the second light guide portion provided such that side surfaces thereof are connected to side surfaces of the first light guide portion and the second light guide portion. A thickness of the intermediate light guide portion is smaller than a thickness of the first light guide portion and a thickness of the second light guide portion. A side surface of the intermediate light guide portion on a side of the prism surface is continuous with the prism surface in a same plane.

摘要： A lighting device includes a light source portion, a light guide that includes a light guide body with an elongated shape, guides light incident from the light source portion in a longitudinal direction of the elongated shape, and emits the light in an emission direction substantially orthogonal to the longitudinal direction, and a bezel that is provided along the light guide and includes an elongated-shaped opening through which the light emitted from the light guide passes and is emitted to the outside. The bezel includes at least one bridge portion that is formed along a lateral direction of the opening so as to partially bridge opposed walls of the opening in the lateral direction.

摘要： A lighting device includes a first light source portion, a light guide that includes a light guide body with an elongated shape, guides light incident from the first light source portion in a longitudinal direction of the elongated shape, and emits a first light including the guided light to illuminate an illuminated object, and a second light source portion that emits a second light to illuminate the illuminated object. The second light source portion is provided independently of the first light source portion and the light guide.

摘要： An illuminating device includes a light source having a light-source optical axis, a lens that is located substantially parallel to the light-source optical axis such that a surface of the lens faces the light-source optical axis, the lens extending to a position rearward of the light source in a direction of the light-source optical axis, and a light reflecting portion located so as to be opposed to a front side of the light source, the light reflecting portion being adapted to reflect emitted light of the light source obliquely rearward of the light source, and reflect the emitted light toward the lens.
