An embodiment may comprise a lighting device comprising: a substrate comprising a first side surface to a fourth side surface; a resin layer including a plurality of grooves including a bottom surface, an exit surface, and an inclined surface; a plurality of light emitting devices disposed inside the grooves and emitting a first light; a reflective layer formed on the inclined surface; and a diffusion layer disposed on the resin layer. The plurality of grooves extends in a direction from the third side surface to the fourth side surface and are arranged in a direction from the first side surface to a second side surface. The plurality of grooves includes a first groove closest to the first side surface of the substrate and a second groove adjacent to the first groove. The first light emitted from the light emitting device disposed in the second groove is reflected off the reflective layer formed on the inclined surface of the second groove, passes through the exit surface of the second groove, is reflected off the reflective layer formed on the inclined surface of the first groove and passes through the resin layer and the diffusion layer.

An optical element including a light entering surface and a light exiting surface is provided. The light exiting surface is opposite to the light entering surface, and includes a first portion, a second portion, and a third portion. The first portion is a curved surface. The second portion is a curved surface and spaced from the first portion by a step difference. The third portion extends from the first portion to the second portion along a first extending direction, wherein the first portion extends along a second extending direction, and the first extending direction is inclined with respect to the second extending direction. An optical module and a lens carrier are also provided.

A vehicle lamp system, a vehicle lamp, and a method for manufacturing a vehicle lamp system relating to the technical field of automobile lamps/lighting are provided. In one implementation, the vehicle lamp system may comprise a light reflective element and at least one light source, with the light source(s) disposed opposite to the light reflective element, wherein the light reflective element is configured to reflect light emitted from the light source in a diffuse manner to achieve uniform illumination. Vehicle lamp systems and the vehicle lamps provided in accordance with the disclosed technology may possess the advantage of better light uniformity.

A vehicle mirror device includes a mirror housing attached to a vehicle and a mirror that is held by the mirror housing and transmits light from inside of the mirror housing while reflecting light from outside of the mirror housing. The mirror housing accommodates therein a light source, a reflector having a reflective surface that reflects light of the light source, and a mask having a light transmitting part through which the light from the light source reflected by the reflector is projected. The light source and the reflector are arranged so that the light is projected toward the light transmitting part of the mask by one time of reflection, and the reflector is arranged so that the reflected light is projected at an angle with respect to a normal line of a reflective surface of the mirror.

A lighting structure for an exterior vehicle light unit has a light source with a principal light emission direction, at least one LED, a substantially parabolic reflector arranged to reflect light output from the light source in a first output region and to collimate the same in a primary light output direction. The light source is arranged in such a way with respect to the substantially parabolic reflector and the aspherical collimating lens that the principal light emission direction is inclined at an acute angle with respect to the primary light output direction.

A vehicle decorative lighting device and a vehicle lamp including the lighting device includes a light guide formed in a nearly ring shape and a pair of light sources that can emit various color lights. Each of the light sources can be located at a respective one of incident surfaces of a lighting body including the light guide. The vehicle lamp can include a lamp room between an outer lens and a casing, and can incorporate various vehicle lamps such as a headlight along with the lighting device in the lamp room. The lighting device can be located in the lamp room so as to emit various color lights while surrounding a vehicle lamp. Thus, the disclosed subject matter can include providing vehicle lamps including the decorative lighting device having a harmonious favorable light distribution, for example, such that combine a headlight with a position lamp with a thin structure.

A light module comprising a means for supporting at least one collector of light rays in the vicinity of which there is a light guide suitable for guiding the rays emitted by a light source from an input face to at least two distinct and adjacent output faces. A distinction is made between a main output face, through which the rays pass in a first direction, and at least one additional output face which is oriented such that the light rays leaving the guide through this additional output face are directed toward the collector, in a second direction distinct from the first direction.

A light beam forming module, in particular in the vehicle external lighting system, is in the form of a monolithic body formed of a plurality of contiguous cross-sectional segments, each of which includes an entrance surface facing the light source, an exit surface, and a first total internal reflection surface and at least another total internal reflection surface. A first total internal reflection surface is positioned downstream of the entrance surface, and at least one further total internal reflection surface has a shaped optical structure formed thereon.
