VEHICLE HEADLIGHT
Document Type and Number:
WIPO Patent Application WO/2023/054513
Kind Code:
A1
Abstract:
A vehicle headlight (1) comprises: a first light-emitting optical system (LE1) for emitting first light (L1); a second light-emitting optical system (LE2) for emitting second light (L2); a projection lens (35); a beam shaper (50) that is formed from a plate-like body part (51) having a slit (54), and an additional part (60). The additional part (60) has: a plate-like fixed section (61) that extends along a lower surface (51S1) of the body part (51); and a plate-like light shielding section (62) that penetrates through the slit (54) from an outer edge of the fixed section (61) and extends upward of an upper surface (51S2) of the body part (51). A part of the first light (L1) is reflected by the upper surface (51S2) toward the projection lens (35) such that a cutoff line (CL) of a low beam light distribution pattern (PL) is formed. A portion protruding from the upper surface (51S2) in the light shielding section (62) shields the other part of the first light (L1).
