Abstract
Official abstract text for this publication.
The lamp assembly for a vehicle according to an embodiment of the present invention includes a light source unit configured to irradiate light, and a lens unit configured to emit the light from the light source unit toward the outside of the lamp assembly. More specifically, the lens unit includes a non-circular-shaped lens on which a light intensity adjusting portion, which adjusts intensity of the light emitted in a lateral side direction, is formed.
First claim
Opening claim text (preview).
What is claimed is: 1. A lamp assembly for a vehicle, comprising: a light source unit configured to irradiate light; and a lens unit having a non-circular-shaped lens configured to emit the light from the light source unit toward an outside of the lamp assembly, wherein the lens unit includes a light intensity adjusting portion formed on a lateral side of the lens unit, such that low intensity light passing through the light intensity adjusting portion emitted in a lateral side direction and high intensity light passing through a portion of the lens unit on which the light intensity adjusting portion is not formed is emitted in a front side direction, and wherein the light intensity adjusting portion includes a knurling structure formed at a side of the lens unit, wherein the knurling structure includes a first end that extends in a linear arrangement along an edge of the lens unit and a second end that forms an arc shape on a sidewall of the lens unit. 2. The lamp assembly of claim 1 , wherein a light source of the light source unit is a light emitting diode (LED). 3. The lamp assembly of claim 1 , further comprising: a shield unit configured to block a portion of the light irradiated from the light source unit so as to form a light irradiation pattern. 4. The lamp assembly of claim 1 , wherein the knurling structure has varying lengths. 5. The lamp assembly of claim 1 , wherein the knurling structure is arranged in parallel to each other in one direction. 6. The lamp assembly of claim 1 , wherein the knurling structure is arranged in a lattice pattern.
