Abstract
Disclosed is a vehicle lamp a pair of lamp modules configured to irradiate light to form a pair of left and right light distribution patterns. Each of the lamp modules includes first and second lamp units. Further, irradiation light from the first lamp unit forms a first light distribution pattern having a vertically extending cutoff line at a center side of a pair of left and right distribution patterns, and irradiation light from the second lamp unit forms a second light distribution pattern near the cutoff line. The second light distribution pattern is smaller and brighter than the first light distribution pattern.
Claims12
A vehicle lamp comprising:
- a pair of lamp modules configured to irradiate light to form a pair of left and right light distribution patterns,
- wherein each of the lamp modules includes first and second lamp units, and is configured to form each of the pair of left and right light distribution patterns as a synthesized light distribution pattern of a first and a second light distribution patterns formed by irradiating light from the first and second lamp units, respectively,
- the first lamp unit is configured to form the first light distribution pattern having a vertical cutoff line at a center side of the pair of left and right light distribution patterns,
- the second lamp unit is configured to form the second light distribution pattern in the first light distribution pattern and located near a lower edge of the first light distribution pattern toward near the vertical cutoff line of the first light distribution pattern, the second light distribution pattern being smaller and brighter than the first light distribution pattern, and
- each of the pair of lamp modules is configured to be rotatable in left and right directions about an axis passing through a central portion of each of the lamp modules when viewed from a top such that the pair of left and right light distribution patterns is integrally or separately formed,
- wherein the pair of lamp modules is rotated by a predetermined amount in a direction in which the pair of lamp modules is moved away from each other in left and right directions, thereby positioning the vertical cutoff line of the first light distribution pattern of the left light distribution pattern (CLL) and the vertical cutoff line of the first light distribution pattern of the right light distribution pattern (CLR) at a left side and a right side of a foregoing vehicle with reference to an own vehicle, respectively, and each of the pair of lamp modules is rotated such that a distance between the vertical cutoff line CLL and the vertical cutoff line CLR is changed depending on a distance between the foregoing vehicle and the own vehicle.
