  • Patent number: 11079088
    Abstract: A lamp for a vehicle includes a light source part including a light source, a first lens part including a plurality of micro incidence lenses on which light generated from the light source part is incident, a second lens part including a plurality of micro emitting lenses each corresponding to each of the plurality of micro incidence lenses, and a shield part disposed between the first lens part and the second lens part. The shield part includes a plurality of shields configured to block some of the light incident from the plurality of micro incidence lenses on the plurality of micro emitting lenses. In particular, a light axis of the light source may be disposed to be spaced apart from a center line which connects centers of an incidence surface and an emitting surface of the first lens part in at least one of a side direction or a downward direction.

  • Patent number: 10533724
    Abstract: Provided is a lamp for a vehicle capable of ensuring light efficiency to satisfy the performance requirements for light distribution. The lamp includes a light source portion, a first lens portion with a plurality of micro incident lenses onto which light generated by the light source portion is incident, a second lens portion with a plurality of micro exit lenses corresponding to the plurality of micro incident lenses, respectively, and a shielding portion with a plurality of shields that are disposed on rear focal points of the plurality of micro exit lenses to obstruct a portion of incident light. In particular, a focal distance of a micro exit lens among the plurality of micro exit lenses is shorter than a focal distance of a micro incident lens among the plurality of micro incident lenses, which corresponds to the micro exit lens.

  • Patent number: 10274153
    Abstract: Provided is a lamp for a vehicle which is capable of forming a beam pattern having a cutoff line with a moderate sharpness. The lamp includes a light source portion, a first lens portion with a plurality of micro incident lenses, a second lens portion with a plurality of micro exit lenses corresponding to the plurality of micro incident lenses, respectively, and a shielding portion which includes a plurality of shields which form a plurality of illumination regions for forming a beam pattern by obstructing a portion of light which is incident onto each of the plurality of micro exit lenses. In particular, upper boundary lines of illumination regions formed by a first set of the plurality of shields are formed in positions different from those of upper boundary lines of illumination regions formed by a second set of the plurality of shields.
