A lens assembly for implementing a low beam may include: a first lens including an incident surface having a shape enclosing a light emitting diode (LED), and an exit surface through which light of the LED exits in a direction perpendicular to the exit surface; and a second lens disposed on the exit surface of the first lens and configured to project the light of the LED that exits from the exit surface. The light of the LED that is projected through the second lens may form a low-beam pattern.

A vehicle lamp includes a first light source configured to emit first light, a first reflective member configured to reflect the first light downward with respect to a vehicle advancing direction, a second reflective member configured to reflect some of the first light reflected by the first reflective member upward with respect to the vehicle advancing direction, a second light source disposed below the second reflective member and configured to emit second light in the vehicle advancing direction, and a projection lens configured to project the first light and the second light in the vehicle advancing direction, wherein the projection lens has a refracting surface configured to refract at least some of the second light downward than an optical axis of the second light.

A vehicle lamp comprises a light source for road surface drawing configured to emit light becoming a light source image, and a projection lens, which has an optical axis extending in a front and rear direction and the light is to pass therethrough. The vehicle lamp can form a plurality of light distribution patterns on a road surface over a range from a position close to the lamp to a position distant from the lamp by the light emitted from the light source and having passed through the projection lens, and the respective light distribution patterns are to be projected on the road surface at states where relative positions between the projection lens and the light source image are different.

A projection lens on a vehicle headlight includes a light incident surface and a light emitting surface facing away from the light incident surface. The light emitting surface includes a diffusing surface and a rough surface. A number of strips protrude from the diffusing surface. The strips are parallel to each other and have curved cross sections, and are configured for diffusing the light passing through the diffusing surface. The rough surface is positioned above and connected to the diffusing surface to form a horizontal connecting line, thereby allowing the rough surface to scatter the light passing through the rough surface in all directions.

A single-piece optical part made of transparent or translucent material, comprising a plurality of active surfaces arranged to form a beam, including an entrance dioptric interface and an exit dioptric interface, inactive surfaces joining the active surfaces, at least one of the inactive surfaces comprising a scattering segment so as to scatter the rays that reach it.

A lighting device for a vehicle may include a light source and a first reflecting unit configured to reflect a beam emitted from the light source. The lighting device may also include a lens in which the first reflecting unit is provided on a partial area of a surface of the lens. The lighting device may also include a reflective fluorescent body configured to convert a wavelength of light reflected from the first reflecting unit; and reflect, into the lens, the wavelength-converted light reflected from the first reflecting unit. The reflective fluorescent body may be disposed on a rear side of the lens and faces a rear surface of the lens. The first reflecting unit may be disposed so as not to be linearly aligned with the light source and the reflective fluorescent body.

A vehicle lamp comprises a first light source group for forward illumination comprising at least one light emitting element, a second light source group for road surface drawing comprising at least one light emitting element provided separately from the at least one light emitting element, a single projection lens through which lights emitted from the first and second light source groups are to pass, and a light shade arranged between the first and second light source groups and the projection lens so that the light from the first light source group and the light from the second light source group do not intersect with each other before entering the projection lens. The projection lens has a first region through which the light from the first light source group is to pass and a second region through which the light from the second light source group is to pass.

A vehicle lamp comprises a first light source group for forward illumination comprising at least one light emitting element, a second light source group for road surface drawing comprising at least one light emitting element provided separately from the at least one light emitting element, a first projection lens through which light emitted from the first light source group is to pass, a second projection lens through which light emitted from the second light source group is to pass, and a light shade arranged between the first and second light source groups and the first and second projection lenses so that the lights from the first and second light source groups do not intersect with each other before entering the first and second projection lenses, respectively. Light distribution control functions of the first and second projection lenses are different from each other.

A projection headlight for a vehicle is provided comprising at least one light source, a projection lens, a condenser lens arranged between the at least one light source and the projection lens, and at least one printed graphic arranged between the condenser lens and the projection lens. The condenser lens has a flat side and a curved side. The at least one printed graphic is printed on the flat side of the condenser lens. Further, a vehicle is provided having at least one such projection headlight.

A lens for forming a beam pattern in a low-beam zone III, a vehicle illuminator, and an automobile. The lens for forming the beam pattern in the low-beam zone III comprises a lens main body. A low-beam zone III formation structure is provided at or integrally formed with a light-entering surface of the lens main body. The low-beam zone III formation structure comprises multiple protrusions protruding from the light-entering surface and is used to diffuse light. The lens for forming the beam pattern in the low-beam zone III has a simple structure, a small volume and high optical efficiency.
