Claim Text:
1. A lighting unit configured to project light in a projection direction in a linear fashion elongated in a direction orthogonal to the projection direction, the lighting unit comprising: a light source oriented in a first orthogonal direction substantially orthogonal to a front-to-rear direction; and a light guide body configured to receive light emitted from the light source and guide the light, so that the guided light can be projected through the light guide body and be directed forward, the light guide body including: the pair of second reflecting surfaces are configured to be curved so as to internally reflect the light from the light incident portion to direct the light substantially radially toward respective sides of the lighting unit in the second orthogonal direction, and both the pair of the third reflecting surfaces are configured to extend more forward than the pair of second reflecting surfaces.
