Abstract:
A light emitting module used in a vehicle headlamp is provided with a light source having a light emitting plane directing toward a front side of a lighting unit, a projection lens disposed ahead of the light source, and a reflecting plane extending in an oblique and forward direction from a side of the light source. The projection lens is disposed by setting a focal point in a vicinity of a lower side of the light emitting plane. The reflecting plane has a structure so that a light emitted from the light source is reflected toward a lower region from a cut line.
