Vehicle lamp

A vehicle lamp comprising:

• a projection lens including an output surface having a convex shape based on only one circular arc;
• a first light source arranged at a rear of the projection lens;
• and
• a second light source arranged at the rear of the projection lens,
• wherein the projection lens has a first back focal point and a second back focal point,
• wherein the first light source is arranged at a position corresponding to the first back focal point, and
• wherein the second light source is arranged at a position corresponding to the second back focal point.

A vehicle lamp comprising:

• a first light source configured to emit light for forming a light distribution pattern for low beam;
• a first array light source including a plurality of semiconductor light emitting elements aligned in at least one row extending in a left-right direction of the vehicle lamp;
• and
• a second array light source including a plurality of semiconductor light emitting elements aligned in at least one row extending in the left-right direction of the vehicle lamp,
• wherein the first array light source is configured to emit light for forming at least a part of an additional light distribution pattern for high beam, and
• wherein the second array light source is configured to emit light for forming an additional light distribution pattern that is to overlap with both the light distribution pattern for low beam and the additional light distribution pattern for high beam on a vertical virtual screen ahead of the lamp.

A vehicle lamp comprising:

• a projection lens having a plurality of focal points;
• a first array light source arranged at a rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row;
• and
• a second array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row,
• wherein the first array light source and the second array light source are arranged in an upper-lower direction of the vehicle lamp,
• wherein the plurality of semiconductor light emitting elements of the first array light source are configured to be individually lit on and off,
• wherein the plurality of semiconductor light emitting elements of the second array light source are configured to be individually lit on and off, and
• wherein in light distribution patterns to be projected on a vertical virtual screen ahead of the lamp, a light distribution pattern which is to be formed by the respective semiconductor light emitting elements of the first array light source and a light distribution pattern which is to be formed by the respective semiconductor light emitting elements of the second array light source are offset in a left-right direction of the vehicle lamp.
