    Abstract: The instant disclosure illustrates a light distance-adjustable vehicle lamp including a lens unit, a light emitting group and a datum axis. The lens unit includes a first focus, a second focus, a lens focus and an optical axis. The light emitting group includes a first light emitting unit and a second light emitting unit. The first light emitting unit includes a first light source center, a first axis and a first light emitting surface, the first light emitting unit corresponds to the first focus of the lens unit. The second light emitting unit includes a second light source center, a second axis and a second light emitting focus. The datum axis passes through the lens focus and the second light emitting unit.

    Abstract: The invention relates to a light guiding element (1) for a laser vehicle headlight (2), wherein the laser vehicle headlight (2) comprises at least one laser light source (3) and at least one luminous element (4) which can be irradiated by the laser light source (3) and can thus be excited to emit visible light, and the light guiding element (1) can substantially be arranged between the laser light source (3) and the luminous element (4), wherein the light guiding element (1) has a light entrance surface (5) and a light exit surface (6), wherein the entrance cross-sectional area of the light entrance surface (5) is greater than the exit cross-sectional area of the light exit surface (6), and the light radiated in through the light entrance surface (5) can be concentrated in the direction of the light exit surface (6) via the inner surface (7) connecting the light entrance surface (5) and the light exit surface (6). The invention additionally relates to a vehicle headlight (2) comprising at least one light guiding element (1) of this type.

    Abstract: A headlight device includes: a light source that emits light; a light guide element that receives the light emitted from the light source through an incident surface and guides the received light to emit the guided light from an emitting surface; and a radiation optical system that radiates the light emitted from the emitting surface ahead of a vehicle. The light guide element includes: a first light guide portion that extends from the incident surface to the emitting surface and guides the received light; and a second light guide portion that is in contact with the first light guide portion, extends from the incident surface to the emitting surface, and guides the received light. The first and second light guide portions have different refractive indexes. The light guide element is configured so that part of light entering the first light guide portion can enter the second light guide portion.
