A shield for improving dark parts in a light emission area of a lamp, wherein the shield is disposed between a reflector and an aspherical lens of the lamp to control light emission area, the shield comprising:
- a first shield part including a shield surface disposed at a same height as a focal height of the aspherical lens;
- a reflection part including a reflecting surface in contact with one end of the first shield part and having a predetermined angle with respect to the shield surface;
- and
- a dark part improvement element configured to diffuse light to a predetermined generation area of the dark part in the light emission area.
A projection headlamp comprising:
- a light source configured to generate light;
- an aspherical lens configured to transmit the generated light of the light source outside of the projection headlamp to a headlamp emission area;
- and
- a reflector configured to receive the generated light from the light source, and to transmit the received light to the aspherical lens, and including a shield for improving dark parts in the headlamp emission area, wherein the shield is disposed between the reflector and the aspherical lens,
- wherein the shield includes:
- a first shield part including a shield surface disposed at a same height as a focal height of the aspherical lens;
- a reflection part including a reflecting surface in contact with one end of the first shield part and having a predetermined angle with the shield surface;
- and
- a dark part improvement element configured to diffuse light to a predetermined generation area of the dark part in the light emission area.
