An IR illuminator used during the operation of autonomous vehicles, which provides improvement in the performance of cameras used in the vehicle at night time. An optical design of an outer lens of the IR illuminator is selected so that the outer lens forms a beam pattern for the output light from the IR light source, and also acts as a light guide for light emitted from a secondary visible light source, which is located in the same module as the IR light source, and which may be positioned on the same or a different printed circuit board as the IR light source. The material of outer lens is opalescent including scattering bodies. The optical design of the outer lens allows for improved field of view of the IR illuminator.

An illumination device includes a housing, having an opening, a substrate, a light source, and a light guide. The opening extends through the housing from a first side to a second side of the housing, and includes a first space and a second space. The light guide is disposed across the first space and the second space. The housing has a wall surface that faces the second space and contacts the light guide, a guide rib that extends in a second direction, and a fitting wall that extends in a third direction. The light guide has a first contact surface that contacts the wall surface so as to position the light guide in a first direction, and a guide groove that is fitted to the guide rib so as to position the light guide in the third direction while guiding movement of the light guide in the second direction.

A method and an illumination arrangement for generating image effects in the interior of a motor vehicle or also outside the motor vehicle. To use existing installation space as efficiently as possible, light is radiated, in the form of at least a first optical reference wave field, onto a irradiation surface that is arranged laterally on an optical image storage device. In the optical image storage, which contains a holographic layer or a diffractive optical layer, the optical reference wave field is transformed into at least a first image wave field and is emitted on an emission side, at a first angular offset with respect to the irradiation surface.

Provided is a lighting device, comprising: a light source module comprising: at least one light source disposed on a printed circuit board; and a resin layer disposed on the printed circuit board so that the light source is embedded; a light reflection member formed on at least any one of one side surface and another side surface of the resin layer; and a diffusion plate having an upper surface formed on the light source module, and a side wall which is integrally formed with the upper surface and formed to extend in a lower side direction and which is adhered onto the light reflection member, wherein a first separated space is formed between the light source module and the upper surface of the diffusion plate, whereby flexibility of the product itself can be secured, and durability and reliability of the product can be also improved.

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 vehicular illumination system includes a ground illumination module disposed at a side door of a vehicle. The ground illumination module includes a reconfigurable display element and at least one light source operable to emit light. When the at least one light source is electrically powered, light emitted by the at least one light source illuminates a ground region adjacent the vehicle. When the at least one light source is electrically powered, light emitted by the at least one light source passes through the reconfigurable display element and the ground illumination module projects an icon established by the reconfigurable display element onto the ground region. The reconfigurable display element is reconfigurable to form the icon responsive to programming of the reconfigurable display element for an icon.

A lighting apparatus includes a plurality of fiber optic panels coupled to respective light sources. The fiber optic panels include a set of optical fibers configured to emit light transversely to the optical axis thereof to form respective illumination regions in the fiber optic panels. A housing is included in the lighting apparatus to have an internal chamber and at least one window formed therein by which the internal chamber is in optical communication with the exterior of the housing. Additionally, an optical system such as a reflector or lens can subtend the light from the distal ends of the fibers within the chamber. The fiber optic panels are coupled to the housing to convey light into the internal chamber while the illumination regions extend from the housing to perform a lighting function of an automotive vehicle.

The invention provides an automotive lighting device associated with vehicle electronics where the device includes light sources, a current sink device and a light driver. The current sink device is connected with the light sources so that each light source with a current sink device forms a light group. The light driver is configured to be electrically fed by a power source where the light driver includes terminals configured to selectively activate or deactivate current flow in each terminal, in such a way that each light group is connected. The light driver is arranged in series with the light groups relative to the power source, either located between the power source and the light groups or located between the light groups and the ground connection. The current sink device includes an input configured to receive an activation signal, in such a way that the current sink device can be selectively activated to consume power.
