A vehicular lighted exterior door handle system includes a lighted exterior door handle assembly having a light module, which includes a circuit board and at least three linearly arranged illumination sources at the circuit board. When the illumination sources are actuated, light emitted by each of the illumination sources is emitted outboard away from the door of the equipped vehicle. With the lighted exterior door handle assembly mounted at the door of the equipped vehicle, and when the illumination sources are actuated with the door of the equipped vehicle unlocked, the light module emits light in a first pattern. With the lighted exterior door handle assembly mounted at the door of the equipped vehicle, and when the illumination sources are actuated with the door of the equipped vehicle locked, the light module emits light in a second pattern that is different from the first pattern.

A light signal device for a driverless transport system, includes a front element having a plurality of optically transparent light exit openings and at least one light generating unit having a light guide and having two light sources arranged at opposite ends of the light guide. The light guide has a plurality of light decoupling elements in order to emit light through the light exit openings. Light exit openings are arranged on the front element in a plurality of rows and a separate light generating unit is provided for each of the rows. A light signal arrangement for a driverless transport system includes a plurality of such light signal devices. A driverless transport system includes the light signal device and a controller. Use of the light signal device is for visualizing an operating state of a driverless transport system. An operating method for the light signal device is also disclosed.

A light module is particularly suited for use in a lighting device for a motor vehicle. The light module has at least one extensive light body and at least one illuminant, the light rays of which are able to exit, or exit, to the outer side via a light-exit area that is surrounded by side areas of the light body. At least one part of the side areas and a back area lying opposite the light-exit area are covered by a reflective or diffusely back-scattering cover. The cover is formed by a frame-like component with a back wall. A side wall of the frame-like component has an opening. The light body is able to be laterally slid into, or is laterally slid into, the frame-like component through the opening. The at least one illuminant is disposed on the side wall with the opening of the frame-like component.

The present invention relates to a vehicle U-turn indicator system to alert other motorists, cyclists and pedestrians of a potential U-turn made by a vehicle. The indicator is an inverted “U” shaped device having LED lights configured to blink in a running manner from one end to other and vice versa. The blinking of LED lights in one direction indicates U-turn of the vehicle in one direction (i.e. left) and in another direction indicates a U-turn of the vehicle in another direction (i.e. right). The indicator can be mounted to the front and rear of the vehicle in addition to side mirrors. An actuator is used for activating the U-turn indicator in a preferred direction.

A light-emitting assembly configured to generate varied color light includes an assembly housing. The light-emitting assembly also includes a light filter element fixed relative to the assembly housing. The light filter element includes a plurality of transparent nanostructured ElectroChromic (TNEC) layers. When at least one of the plurality of TNEC layers is subjected to voltage, the subject TNEC layer(s) imparts a distinct reflective color to ambient light entering the light-emitting assembly. Such a light-emitting assembly may be specifically adapted for use on a motor vehicle.

To promptly detect a failure of a light source. A vehicle headlight system includes a plurality of light sources, a power supply supplying a drive voltage to the light sources, a controller individually controlling a lit/off state of each light source, and a failure detection circuit connected to the controller and detects a failure of the light sources, where, in response to a start of the vehicle, the controller executes a control operation in which all light sources are controlled from the off state to the lit state and then the light sources are controlled to the off state sequentially and individually, and where, while the control operation is executed, at least during the period of transition from the off state to the lit state of each light source, the controller acquires failure detection result and generates a warning signal when the failure is detected.

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.

The present disclosure discloses a vehicle lamp control apparatus. The vehicle lamp control apparatus includes a timing generator configured to detect first and second setting voltages, which are varied, and measure a time in which each of the first and second setting voltages reaches a reference voltage to generate first and second delay times, and a lamp control circuit configured to control sequential turn-on of LED channels using the first and second delay times.
