摘要： A light incident surface of a lens is determined to have a shape of a virtual light incident surface (SF1). The virtual light incident surface (SF1) is defined based on normal directions (ni) respectively calculated at a plurality of light incident points (Pi) of the virtual light incident surface (SF1) such that lights emitted from a first light emitting point (S1) and incident on the respective light incident points (Pi) are projected onto a first projection point (r1) and that lights emitted from a second light emitting point (S2) and incident on the respective light incident points (Pi) are projected onto a second projection point (r2) spaced in a predetermined direction from the first projection point (r1).

摘要： A lamp unit mounted in a vehicle includes a light source, a light source mounting portion on which the light source is mounted, and a projection lens having a front surface with a convex shape and configured to project light from the light source to the front of the lamp unit. When looking at the lamp unit from the front, the front surface of the projection lens takes a substantially round shape which is centered at an optical axis of the lamp unit in a position which lies closer to a front end portion and a substantially non-round shape at a rear end portion. The front surface changing gradually its shape from the substantially round shape to the substantially non-round shape in a region between the position and the rear end portion as it extends from the position towards the rear end portion.

摘要： A vehicle lamp includes a convex lens and a light emitting device. Light directly reaching a rear surface of the convex lens from the light emitting device is deflected through the convex lens to form a light distribution pattern having a horizontal cutoff line and an oblique cutoff line. The light emitting device includes a light emitting chip having a rectangular light emitting surface oriented to face the rear surface of the convex lens, and a corner of the rectangular light emitting surface is disposed on a rear focal point of the convex lens. A front surface of the convex lens includes a horizontally diffusing region which diffuses a part of the light in the horizontal direction, and an obliquely diffusing region which diffuses another part of the light toward the self lane side in an oblique direction forming an upward angle with respect to the horizontal plane.

摘要： A light-emitting element is disposed to face the front side such that an end point of a rectangular or square light-emitting chip corresponding to the vehicle's own lane is positioned at a rear focal point of a convex lens. An additional lens is disposed to surround the convex lens. The additional lens includes an incident surface, a reflection surface, and an emitting surface. The additional lens is divided into a-plurality of fan-shaped areas in a circumferential direction with respect to an optical axis Ax. The division is performed for each angular range where a corner point of the light-emitting chip, which is positioned at an uppermost end of an image of the light-emitting chip formed on the reflection surface by the light emitted from the light-emitting element, becomes the same corner point.

摘要： The reflection surface of a reflector is formed by a parabolic cylindrical plane extending in the horizontal direction orthogonal to an optical axis. A light emitting element is configured to have five light emitting chips arranged in a T-shape and these light emitting chips are lighted in two lighting modes. In the first lighting mode, a special light emitting chip and a pair of the left and right side special light emitting chips which front end edges are aligned on the focal line of the parabolic cylindrical plane are lighted simultaneously, whereby a light distribution pattern having a narrow vertical width and a prolong shape is formed. In the second lighting mode, a special light emitting chip located at the center portion and two general light emitting chips disposed in series on the backward side thereof are lighted simultaneously, whereby a light distribution pattern having a large vertical width and a prolong shape is formed.
