An automotive lighting unit is disclosed that comprises a rear casing fixable to a vehicle, a front bezel forming a rigid container with the rear casing, and a light-guide plate made of photoconductive material inserted in a pass-through manner in a slit in the front bezel. The automotive lighting unit further comprises a lighting assembly which emits light on command and is arranged inside the rigid container facing a rear sidewall of the light-guide plate so as to direct the light produced within the light-guide plate, through the rear sidewall in such a way that the light travels within the light-guide plate by total internal reflection up to the front sidewall of the light-guide plate, and a diffusing filter which is interposed between the lighting assembly and the light-guide plate so as to be crossed by the light emitted by the lighting assembly.

A light source module is provided, including: a light board, including a substrate, and a plurality of light-emitting elements arranged at intervals on the substrate; and a separator, located above the substrate, and including a plurality of first ribs, where the plurality of first ribs is cross-connected to form a plurality of interval spaces, to accommodate the light-emitting elements, the first rib forming the interval space has an inner wall, a part of the inner wall in a direction closer to the substrate tapers in a direction far away from the interval space, the inner wall has a first distance farther away from the substrate in a Z-axis direction and has a second distance closer to the substrate, and a projection relationship between the second distance and the first distance onto an XY plane is that the second distance is greater than the first distance.

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.

The present invention relates to an optical component including a light source configured to emit light, a light guide unit configured to receive and guide light emitted by the light source and output the light from the light output surface of the light guide unit, and a backplate configured to provide support for the light guide unit. The light guide unit includes at least a first portion and a second portion, the at least first portion and second portion being arranged at a certain angle to each other. The present invention further provides a lighting device and a motor vehicle.

A light guide comprises a center body portion that extends along a center axis and which has a first end associated with a light source and an opposite second end associated with a plurality of non-coplanar surfaces. A first leg portion extends away from the center body portion in a first direction and a second leg portion extends away from the center body portion in a second direction opposite of the first direction.

The lighting device disclosed in the embodiment of the invention includes a substrate; a plurality of light emitting devices disposed on the substrate and emitting light in at least a first direction; a resin layer sealing the plurality of light emitting devices; and an optical member disposed on the resin layer, wherein the resin layer may include a first light blocking portion integrally formed with the resin layer and having a transmittance lower than that of the resin layer on an emission-side region of each of the plurality of light emitting devices.

A lighting device for vehicles, comprising a housing containing a light source and an optical unit. The optical unit has a microstructured surface having a plurality of microstructure elements. The microstructure elements are formed from a limited selection of microstructure elements formed differently in at least two extension directions of the surface.

An optical device, a method of manufacturing same, and a vehicle therefor are provided. The optical device includes a printed circuit board (PCB); light emitting diodes (LEDs) spaced apart from each other on the PCB, a light guide layer with the LEDs embedded therein, and a pattern layer stacked on a side surface of the light guide layer to implement a three-dimensional luminescent image using light from the LEDs. The LEDs include at least top-emitting LEDs and/or side-emitting LEDs.
