A rear combination lamp installed on a vehicle comprises: a first rear lamp module installed on a later part of the rear side of the vehicle; and a second rear lamp module installed on a back door located at the rear side of the vehicle to be arranged adjacent to the first rear lamp module. The first rear lamp module includes a main light source and a sub-light source. The main light source generates light output from the first rear lamp module, and the sub-light source generates light provided to the second rear lamp module. The second rear lamp module includes a light reception unit and a light direction changing unit. The light reception unit receives light from the sub-light source. The light direction changing unit changes a progressing direction of light received in the light reception unit to output light to the outside.

A light emitting system includes at least one light pipe, at least one light source disposed at least partially within an interior of the system, at least one mask, and a lens substantially enclosing the interior of the system, the at least one light pipe, and the at least one light source, the lens having an inner surface, an outer surface disposed opposite the inner surface and at least one of a continuous transparent or translucent coating on the outer surface.

The present invention relates to an automotive optical system; the optical system includes one or more first optical elements that reflect light rays emitted from a number of first light sources that are configured to perform a first lighting function and a second optical element; the second optical element is configured to project a light beam from the first optical elements configured to perform the first lighting function where a portion of the second optical element is made of a diffusive material. Furthermore, the optical system includes a number of secondary light sources where the second optical element is configured to receive light ray emissions from the secondary light sources and perform a second lighting function by scattering light rays received from secondary light sources.

A vehicular lamp includes a light source; and a light guide disposed such that light emitted from the light source is incident on an end face of the light guide. The light guide emits light, guided into its interior, heading vehicle-forward from an exit face of the light guide running along the light guide's lengthwise extension. The light guide includes reflection steps formed on a surface of the light guide on a side reverse from the exit face, for reflecting light guided into the light-guide interior toward the exit face; and a plurality of diffusion flutes formed on said end face, each being arcuate in substantially horizontal cross-section through said end face, and each being of constant form in substantially perpendicular extension.

A method is disclosed for manufacturing, by injection molding with use of a mold, a light guide plate in which a first region having a curvature in a first direction and a second region having a predetermined curved surface are connected. The mold includes a first member for forming the first region and a second member for forming the second region. The first member is manufactured by bending a first electroforming stamper on which a predetermined structure is formed by electroforming in a direction corresponding to the first direction.

A light source unit includes: a light source part that emits excitation light; a light emitting part that emits generated light by being irradiated with the excitation light; a support part that guides the excitation light to the light emitting part while supporting the light emitting part; and a reflective part provided on a back surface of the support part, the back surface being on a side opposite to an emission direction of the generated light.

A lighting device disclosed in an embodiment of the invention includes a substrate; a reflective member disposed on the substrate; a plurality of light emitting devices disposed on the substrate; a resin layer disposed on the reflective member; and an optical pattern portion having a plurality of concave portions concavely formed on an upper surface of the resin layer, wherein the plurality of light emitting devices is spaced apart in a first direction in which light is emitted, wherein the optical pattern portion includes a pattern portion in which a width of the concave portions is reduced from a position overlapping a center of each of the plurality of light emitting devices in the first direction, wherein the optical pattern portion includes a pattern portion in which a width of the concave portions is reduced from the center of the optical pattern portion toward both sides of a second direction.

A present invention is a vehicle lamp provided with: an elongated light guide member provided in a lamp chamber, an incident end part being positioned below said member; and a light source provided in the lamp chamber so as to face the incident end part. The light guide member has: a light guide main part having an elongated shape in which one end is the incident end part, a prism part being provided along the longitudinal direction, the prism part causing a portion of the light incident from the incident end part to be emitted in the irradiation direction; and a flange part projecting from the light guide main part in the direction intersecting the irradiation direction. The flange part is provided with a reflecting surface that forms a depression angle with a projecting end face when viewed from the incident end part side within a prescribed range viewed in the longitudinal direction.
