The headlamp optical element comprises a light collecting portion, a first light emitting portion and a reflecting portion, or comprises the light collecting portion, the first light emitting portion, the reflecting portion and a second light emitting portion. The light collecting portion can converge the incident light and emit the light via the first light emitting portion, with some of the light directly emitted to the second light emitting portion, and the rest of the light being reflected by the reflecting portion and then emitted to the second light emitting portion. The reflecting portion is connected to the lower portion of the first light emitting portion, with a lower beam cut-off line structure being formed at the other end thereof, or the reflecting portion is connected to the upper portion of the first light emitting portion, with a high beam cut-off line structure being formed at the other end thereof.

A headlamp includes a high beam lamp unit configured to form a high beam light distribution pattern, a cornering lamp configured to form a side light distribution pattern, and a lamp control unit configured to control the high beam lamp unit and the cornering lamp so as to adjust the high beam light distribution pattern and the side light distribution pattern. At least one of the high beam light distribution pattern and the side light distribution pattern includes a first region including a target object and a second region other than the first region. When an external sensor detects the target object, the lamp control unit adjusts the high beam light distribution pattern and the side light distribution pattern so that at least the second region is irradiated with light.

A vehicle lamp includes: a light source that emits a light; an optical member including a lens that irradiates the light from the light source to a front of the vehicle lamp and forms a predetermined light distribution pattern including a plurality of regions; and a controller that, when an object outside the vehicle is detected, adjusts the predetermined light distribution pattern so as not to irradiate at least one first region including the object among the plurality of regions with the light.
