A through-type lamp for a vehicle includes a light source, an inner cover, a thick wall, and a reflector. The reflector is configured to reflect light, emitted from the light source to the inner cover, and emit the light through the inner cover and the thick wall sequentially. The inner cover and the thick wall each have a one-piece structure. Two ends of the inner cover and two ends of the thick wall extend towards two sides of a vehicle to side lamp regions. The light source and the reflector each extend along an extension direction of the thick wall. The vehicle includes the through-type lamp.

The present invention provides a lighting device including a light source, a printed circuit board, an optical face and a lens, with the light source being mounted on the printed circuit board, and at least a portion of light rays emitted by the light source towards the optical face are guided by the optical face and then emerge through the lens. At least one light shielding electronic element is also mounted on the printed circuit board, for blocking at least a portion of light rays emitted by the light source towards the lens, to prevent this portion of light rays from emerging through the lens directly.

An illumination device for a motor vehicle light has a plate-like transparent light guiding body (LGB). Light sources are arranged on a narrow side of the LGB and emit light that enters the LGB and propagates therein in a first main light propagation direction (X.sub.1) to the opposite narrow side. At least some of the light rays (S1), incident on the front main surface (FMS) of the light propagating in the X.sub.1 direction are totally reflected at the FMS such that the light strikes a rear main surface (RMS), which has an exit structure. At least some of the light rays (S1) which are totally reflected at the FMS and which strike the RMS exit the LGB via the exit structure. A reflector surface, which is arranged opposite the RMS, is designed such that light rays (S1) emerging from the RMS and striking the reflector surface are deflected by the reflector surface in the direction of the LGB in a second light propagation direction (X.sub.2) and the deflected light rays (S1) pass through the RMS and the FMS and are emitted into an area in front of the illumination device to form a light distribution.

A lamp includes a housing, an outer surface cover, and a light guide structure. The housing and the outer surface cover define a light chamber. The light guide structure further includes a light source, an inner cover and a reflector, the reflector is coupled to the housing and configured to reflect the light emitted from the light source to the inner cover, and emit the light through the inner cover and the thick wall in sequence.

This invention relates to a lighting device for vehicles having a housing, which is arranged in a corner region of a vehicle, having a light-permeable lens which closes off an opening of the housing, wherein a light module with a light source and with an optical unit for generating a predetermined light distribution is arranged in the housing and wherein a side marker reflex reflector extending in the main beam direction of the lighting device and containing reflex reflector elements for side marking of the vehicle is arranged in the housing, wherein the side marker reflex reflector is arranged in main beam direction behind at least a part of the light module.

A lighting device disclosed in an embodiment of the invention comprises a substrate; a plurality of light sources arranged in a second direction on the substrate; a lighting module having a light guide portion disposed on the substrate and the light sources; an optical lens disposed on the lighting module, the optical lens having an incident surface having a width greater than a width of the lighting module in a first direction, and an exit surface from which light incident on the incident surface is emitted; and a reflecting member having an insertion hole in which the light guide portion is disposed, a reflective portion extending to both sides of the insertion hole and covering both sides of the light guide portion, and a supporting portion supporting a lower edge of the optical lens, wherein the light guide portion and the insertion hole have a width in the first direction smaller than a length in the second direction, and an upper end of the reflective portion may be positioned higher than an upper end of the light guide portion.

The present invention provides a lighting device including a light source, a printed circuit board, an optical face and a lens, with the light source being mounted on the printed circuit board, and at least a portion of light rays emitted by the light source towards the optical face are guided by the optical face and then emerge through the lens. At least one light shielding electronic element is also mounted on the printed circuit board, for blocking at least a portion of light rays emitted by the light source towards the lens, to prevent this portion of light rays from emerging through the lens directly.

A method includes energizing a light source of a vehicular lamp assembly according to a duty cycle. The light source emits light responsive to being energized. While energizing the light source, and during an off-cycle of the duty cycle, the method includes transmitting an outgoing short-range wireless communication to a user device. The outgoing short-range wireless communication is transmitted from an antenna at the vehicular lamp assembly. During the off-cycle of the duty cycle, the method includes receiving an incoming short-range wireless communication at the antenna at the vehicular lamp assembly. The incoming short-range wireless communication is transmitted from the user device responsive to the outgoing short-range wireless communication.

A light source unit for a vehicle lamp includes a light generating portion including a light source that emits excitation light, a light emitting layer constituted of an inorganic material and emitting generated light by irradiation of the excitation light, and a holding member that holds the layer; and a lens member that irradiates the generated light from the layer in a front direction in a vehicle-mounted state. The unit further includes a reflective portion disposed between the layer and the lens member, capable of reflecting a part of light from outside of the lens member, and capable of transmitting the generated light generated in the layer; or a light absorbing portion disposed between the layer and the lens member, and absorbing a part of a wavelength component among light from outside of the lens member being associated with the generated light.

A light-emitting module and a vehicle lamp including the same are provided. The light-emitting module includes: a substrate formed of a transparent material; at least one light source installed on a rear surface of the substrate to emit light in a first direction; a deflection part disposed at a rear of the substrate to cause the light emitted in the first direction to be deflected in a second direction; a holder disposed at the rear of the substrate to support the substrate; and a transmissive material disposed between the substrate and the holder.
