A multi-function lighting assembly provides multiple vehicle lighting functions (e.g., rear vehicle tail light and fog light) using a single printed circuit board substrate having mini or micro chip scale package LEDs or their unpackaged LED dies. LEDs for respective ones of the different lighting functions are separately controlled. LEDs controlled for respective functions can be interspersed, or disposed in different areas of LEDs having the same lighting function. A layer of optic components is disposed relative to the outputs of the LEDs and has different optic components for the LEDs of the respective lighting functions (e.g., collimator optics over LEDs controlled to provide a bright concentrated light output, and a diffuser over the LEDs controlled to provide a diffused light output). The multi-function lighting assembly can be employed as a universal board for seamless and convenient integration into various rear lamps having specific inner tail lenses.

A vehicle light includes a lighting unit with multiple light-emitting elements (LEEs), one or more couplers, a light guide and an extractor. The lighting unit has a curved elongate extension. Each of the couplers has an input aperture coupled with one or more of the LEEs and an exit aperture coupled with a first edge of the light guide and is configured to couple light from the LEEs into the light guide. The light guide is configured to propagate light via total internal reflection to a second edge of the light guide. The extractor has an input aperture coupled with the second edge of the light guide and an exit aperture configured to emit light into an ambient environment.

A lighting device including at least two LED light sources configured for individual activation; at least two light guides arranged adjacent to one another, each including an edge surface facing a respective one of the LED light sources, a back surface extending from the edge surface provided with a plurality of diffuser extractor elements, and a front surface extending from the edge surface and opposite the back surface; and opaque barrier walls provided between the at least two light guides and extending from the rear wall to the front wall, to mechanically and optically separate the light guides. The light guides are configured to receive light from the LED light sources, with the diffuser extractor elements arranged shaped redirect received light traveling within the light guide to be projected through the front surface.

A lamp apparatus may include: a housing; a board housed in the housing; a plurality of light source modules mounted on the board and configured to generate light; an optic unit through which lights emitted from the plurality of light source modules enter and exit; a lens unit installed in the housing, and installed in front of the optic unit; and a control unit configured to individually turn on/off the plurality of light source modules.

A vehicle lamp includes a light source system; a reflection system including a plurality of reflective faces to reflect light beams emitted from the light source system to travel forward; and an optical system including a plurality of lenses respectively corresponding to the plurality of reflective faces. The optical system is configured to transmit at least a portion of light reflected from each of the plurality of reflective faces through a corresponding lens among the plurality of lenses to form a predetermined light irradiation pattern.

The present invention refers to a detector device for detecting a status of at least a first electronic element of an automotive lighting device. This detector device comprises a status detection unit configured to detect a status of the at least first electronic element and to generate a reference signal which depends at least on the status of the first electronic element. It also comprises a comparison signal generator configured to generate a comparison signal and a comparison unit configured to generate a pulse-width modulation signal by comparing the reference signal with the comparison signal.

The present invention relates to a light-guiding assembly having a first light-guiding element, which is allocated to a first light source and used to receive and guide light from the first light source, and is provided with a first light incidence portion, a first light exit portion, and a first intermediate optical portion that is arranged between them. A second light-guiding element, which is allocated to a second light source and used to receive and guide light from the second light source, and is provided with a second light incidence portion, a second light exit portion, and a second intermediate optical portion that is arranged between them. Wherein the first light exit portion faces the second intermediate optical portion, and light leaving the first light exit portion can pass through the second intermediate optical portion and exit from the second light exit portion.

A vehicle exterior part is configured to be arranged frontward of a millimeter wave radar device with respect to the transmission direction of millimeter waves. The vehicle exterior part includes an ornamental body, a light source that emits light, and a light diffuse reflection member. The light diffuse reflection member is millimeter wave-transmissive and diffuses and reflects light. The ornamental body includes a base and an ornamental layer. The base is millimeter wave-transmissive and diffuses and transmits the light. The ornamental layer is millimeter wave-transmissive and arranged frontward of the base with respect to the transmission direction. The light source, the ornamental body, and the light diffuse reflection member are arranged so that the light emitted from the light source is diffused and reflected by the light diffuse reflection member and directed toward the base.

An illumination device for a motor vehicle includes a multi-aperture projection display having a lighting means for illuminating a plurality of image segments and an array of projection lenses, where each projection lens is assigned an image segment, from the plurality of image segments, that is projected into a projection plane by way of a corresponding one of the projection lens, such that a light distribution is produced from all of the projected image segments in the projection plane. The array of projection lenses comprises a plurality of subarrays, where a respective subarray contains the same projection lenses and the projection lenses of different subarrays differ from one another such that each subarray generates a surface area in the light distribution and a size and/or a position of the generated surface areas varies between the plurality of subarrays.
