Definitions

  • the present invention relates to a vehicle headlamp. More particularly, the invention relates to a vehicle headlamp in which a relative position of a light source body and an optical component for reflecting or projecting the light from the light source body is varied, thereby reducing a size and cutting down a manufacturing cost, and furthermore, enabling switching of a light distribution pattern.
  • a vehicle headlamp in which a lamp unit having a projection lens and a light source such as a light emitting diode is disposed in an outer casing of a lighting device which is formed by a cover and a lamp body (for example, see JP-A-2010-153333 ).

That is, since the shade is disposed apart from the light source in the forward direction, a length in a direction of an optical axis (a longitudinal direction) is correspondingly increased so that a reduction in a size is hindered.
  • the vehicle headlamp of JP-A-2010-153333 requires the shade and a shade driving mechanism for driving the shade. Therefore, a space for disposing them is required. So, there is also a problem in that the reduction in the size is still hindered and a manufacturing cost rises.
