More Information
Summary:The invention provides a lighting device and a headlamp, which can realize a light distribution pattern of low beam and a light distribution pattern of high beam by one light emitting part. The lighting device (100) is provided with: a light-emitting unit (110); a reflector (120) that reflects a first portion of the light emitted from the light-emitting unit; a first lens (130) having a first incident surface on which the light reflected by the reflector is incident; a second lens (140) having a second incident surface on which a second portion of the light emitted from the light-emitting unit is incident, the distance between the light-emitting unit and the second incident surface in the horizontal direction being smaller than the distance between the light-emitting unit and the first incident surface in the horizontal direction; a first light shielding member (150) provided between the first lens and the second lens; a second light shielding member (160) positioned between the light-emitting unit and the fi
