    摘要： A low-beam primary optical element (1) for a vehicle lamp, a vehicle lamp module comprising the low-beam primary optical element (1), a vehicle lamp, and a vehicle. The low-beam primary optical element (1) comprises light entrance portion (101), a light passage portion (102) and a light exit portion (103) which are sequentially arranged from back to front. The light exit portion (103) comprises a main light exit surface (1031) and a second light exit surface (1032) connected to the main light exit surface (1031). A low-beam cutoff line structure (105) is provided at the secondary light exit surface (1032). The secondary light exit surface (1032) is configured to refract light emitted to the low-beam cutoff line structure (105) forward and upward. The low-beam primary optical element (1) has a simple structure, and can effectively improve the color of a low-beam light-dark cutoff line (7) and mitigate color dispersion.

    摘要： Provided is a headlight (101). The headlight comprises a light-emitting device (102), wherein the light-emitting device (102) comprises: a first light-emitting module (104) comprising multiple first light-emitting units (106),wherein the arrangement of the multiple first light-emitting units (106) is consistent with a low beam cut-off line (107) of the headlight (101); a second light-emitting module (105) comprising multiple second light-emitting units (108). The headlight further comprises a lens (103) for projecting the light of the first light-emitting unit (106) and/or the second light-emitting unit (108). The distance between the first light-emitting unit (106) and the front focal plane (SF) of the lens (103) being less than the distance between the second light-emitting unit (108) and the front focal plane (SF) can ensure the definition of the low beam cut-off line (107) of the headlight (101) and the uniformity of light in other illumination areas of the headlight (101),and also improve the light utilization rate.

    摘要： Provided is a vehicular lamp that forms a light distribution pattern for traveling having a lower end portion overlapping an upper end portion of a light distribution pattern for passing and is downsized with a simple configuration. The vehicular lamp includes a projection lens that projects light emitted from a first light source to form the light distribution pattern for passing and projects light emitted from a second light source to form the light distribution pattern for traveling. A lower lens part and an upper lens part are set in the projection lens about a lens axis as a center, a lower focus is set on the lens axis in the lower lens part, and an upper focus shorter in focal length than the lower focus is set on the lens axis in the upper lens part.

    摘要： A vehicle lamp includes a light source and a compound optical lens that emits light forward. The compound optical lens has an incidence surface, an emission surface, and a shade part. The emission surface emits the light received by the incidence surface forward. The shade part is disposed between the incidence surface and the emission surface. The compound optical lens has first and second reflector surfaces. The first reflector surface reflects light forming a first light distribution pattern toward the emission surface. The second reflector surface reflects light forming a condensed-light distribution pattern toward the emission surface. The width of the first reflector surface is larger than the width of the second reflector surface in a vehicle width direction at a position where the first reflector surface and the second reflector surface are adjacent to each other.
