Methods, apparatus and systems are described herein. A light source includes a first light emitting diode (LED) die configured to emit a first die color and a second LED die configured to emit a second die color. A first filling is disposed over the first LED die. The first filling has a convex surface and includes a first phosphor such that the first die color is converted to a first illuminous color. A second filling is disposed over the second LED die. The second filling includes a second phosphor such that the second die color is converted to a second illuminous color that has a higher absorption energy than an illumination energy of the first illuminous color.

A vehicular exterior lighting system includes a lighting module disposed at a side of a vehicle. The lighting module includes at least one light emitting diode. The lighting module is operable to emit light that is viewable by a person exterior the side of the vehicle who is viewing the side of the vehicle. The lighting module emits white light responsive to a signal from a remote device to provide ground illumination of a ground region at the side of the vehicle at which the lighting module is disposed, and the lighting module (i) emits a first color of light responsive to a door lock signal and (ii) emits a second color of light responsive to a door unlock signal. The first color of light is different than the second color of light.

A light emitting system includes at least one light pipe, at least one light source disposed at least partially within an interior of the system, at least one mask, and a lens substantially enclosing the interior of the system, the at least one light pipe, and the at least one light source, the lens having an inner surface, an outer surface disposed opposite the inner surface and at least one of a continuous transparent or translucent coating on the outer surface.

An integrated lighting element assembly includes a transparent light-transmitting portion and an opaque or translucent optical diffuser. The light-transmitting portion has a light-transmitting surface. The optical diffuser is integrated or co-molded with the light-transmitting element to form a boundary of the light-transmitting surface. A light source is configured to direct incident light into the light-transmitting portion in response to a lighting control signal. A controller may generate the lighting control signal in response to activation of a user input device such as a turn signal lever or transmission mode selection lever. The optical diffuser may be parallel to and contiguous with the longitudinal surfaces of the light-transmitting element. A headlight assembly includes first and second headlights having respective low- and high-beam functions, and the lighting element assembly, which is positioned with respect to one of the headlights.

An LED lighting device having an LED lamp series circuit with a first LED lamp and with a second LED lamp that is coupled to the first LED lamp through a lamp coupling point, an anode, a cathode, driver electronics for connection to the anode and the cathode for operation of the LED lamp series circuit, and a detection device for detecting a failure of the first LED lamp and the second LED lamp. The detection device, together with the first LED lamp and the second LED lamp, forms a first measuring bridge circuit. In addition, the invention relates to a motor vehicle with an LED lighting device according to the invention.

A lighting device comprises a light-emitting module with light-emitting elements, wherein the light-emitting elements are arranged adjacent to each other and are configured to emit light towards a light-emitting side. The light-emitting module is configured such that the light-emitting elements can be addressed partially independently of each other, such that some may be brought into a switched-on state while others are brought into a switched-off state. A top layer is disposed on the light-emitting module at the light-emitting side. Further comprising a switching material capable of a reversible change in transmittance for the light emitted by changing to a higher transmittance in regions where the top layer situated on light-emitting elements in the switched-on state or to a lower transmittance in regions of the top layer situated in the switched-off state. The invention further refers to methods for producing and operating a lighting device and using a lighting device.

A lighting device comprises a plurality of light-emitting devices, which are connected to a communication bus in the motor vehicle and receive successive messages from an electronic control unit. The light-emitting devices of the plurality of light-emitting devices are divided into a plurality of groups. Each group is formed of one or more light-emitting devices. One group is associated with each message. Each message specifies one or more operating parameters for an individual light-emitting device. A light-emitting device that is in the associated group of a received message performs its operation based on the operating parameter(s). The electronic control unit changes the division of the plurality of light-emitting devices in groups at least once during the operation of the lighting device.

An automotive vehicle includes a headlamp housing mounted to a body of the vehicle. An airflow opening extends through the headlamp housing. A light guide coupled to the housing forms a portion of an airflow passage extending from the airflow opening into an interior of the body of the vehicle. A surface of the light guide is etched with a design extending along a length of the airflow passage. An LED light generating unit is positioned adjacent an end of the light guide to pass light from the light generating unit through the light guide that illuminates the etched design.

A system for identifying a location of an external vehicle feature on approach by a user of the vehicle is disclosed, comprising (1) a vehicle including a steering system, a drive system, a brake system, a processor, and memory; (2) a control module coupled to the processor and configured to receive a wireless communication from a mobile device indicative of a user's proximity to the vehicle; and (3) a brake module coupled to the control module and configured to illuminate a lighting device on receipt of the wireless communication to identify a location of the vehicle feature.

A vehicle and control method of the vehicle are provided. The vehicle includes a camera provided on the vehicle and configured to capture an image of an object outside the vehicle, a controller configured to determine a photographing position required for facial recognition from the captured image, a guide configured to guide the photographing position, and a display configured to display a result of the facial recognition.
