A lighting unit includes a light guide and a light source. The light guide is provided with a light inlet section, while the light source is provided with a light emitting surface facing the light inlet section. The light inlet section is formed with a plurality of light refracting surfaces inclined relative to the light emitting surface of the light source. Due to the light refracting surfaces, light emitted from the light source is properly distributed through the light guide. |
