Lighting apparatus for vehicles
A lighting apparatus for vehicles, having a light source and a headlamp lens assigned thereto. The headlamp lens has scattering optical elements for scattering the light. A light guide is disposed between the light source and the headlamp lens in such a way that, firstly, light emitted by the light source strikes an area of the headlamp lens delimited by an edge of the same or a portion of the headlamp lens and/or that, secondly, the plurality of light sources are disposed with different spatial orientations with respect to one another in terms of their principal axes such that the light emitted by the light sources strikes different portions of the headlamp lens, wherein the headlamp lens is disposed upstream and/or downstream of the light source in the principal emission direction for the purposes of scattering the light in a transmissive or reflective manner.
Motor vehicle headlamp and method for operating a motor vehicle headlamp
A motor vehicle headlamp that includes a housing in which at least one main light source is arranged. Detachably attached to an external lens of the motor vehicle headlamp is at least one front housing, which has a light-guiding element and lamps for coupling light rays into the light-guiding element. The light rays are coupled out of the light-guiding element through an output structure. Further additional lamps that can give off light rays are arranged side by side in front of the external lens. The light rays given off by the lamps pass through the external lens and the front housing in the direction of an outside environment.
Backlight unit for blind spot warning lighting
A backlight unit for blind spot warning lighting includes a printed circuit board (PCB) mounted with a light-emitting diode (LED), a bottom case having the PCB embedded on a lower portion thereof, and having an opened front surface, and a top case comprising a front plate covering a the front surface of the bottom case, and a guide protrusion formed to protrude backward from a rear surface of the front plate to guide the light from the LED to the front plate, and an object of the present disclosure is to provide a backlight unit, which can uniformly emit light while unifying the number of reflection and diffusion layers, and be advantageous for applying a hot wire, thereby improving visibility.
Automotive lighting and/or signaling device and assembly method thereof
A lighting and signaling device for automotive vehicles, comprising a container body delimiting a containment housing closed by a lenticular body, which accommodates at least one first light source and is closed by a lenticular body, a first light guide configured to receive as input at least partially the light beam produced by the first light source, transmits the light beam by total internal reflection along a first prevailing propagation direction and sends it as output from the lenticular body. A fixing and/or screen element, opaque to the light beam is associated with the first light guide at a first interface wall, and is fixed either directly or indirectly onto the container body to mechanically block the first light guide onto the container body. The first light guide is mechanically fixed to the fixing and/or screen element by at least one first welding portion which projects from the first interface wall.
Light-guiding optical unit for a light device of motor vehicles
The light-guiding optical unit (1) for a light device of motor vehicles comprises a light guide (2) that comprises at least one routing surface (3), and at least one light source (4) to generate light rays (10). The light-guide (2) further comprises a top surface (12) at least a part of which is constituted by the output surface (15), and a bottom surface (13) opposite the top surface (12) and fitted with a prismatic structure (16) comprising reflective surfaces (7). The routing surface (3) and the reflective surfaces (7) are mutually arranged in such a way that the routing surface (3), by means of routing by refraction on this surface (3) or reflection from this surface (3), directs light rays (10) to the prismatic structure (16) in such a way that it directly lights up only the reflective surfaces (7) with the light rays (10), the reflective surfaces (7) being configured to direct light rays (10) that have fallen onto them this way directly from the routing surface (3) to the output surface (15) in such a way that the light rays (10) can exit from the light guide (2) through the output surface (15).
Illumination Device for a Motor Vehicle
An illumination device for a motor vehicle includes at least one light source and an elongated waveguide which is delimited along the length thereof by a lateral surface. The waveguide is configured to guide light from the at least one light source along a light propagation direction in a totally reflective manner, the light propagation direction corresponding to the length of the waveguide. The light of the at least one light source can be coupled into the waveguide via a coupling surface at an end face of the waveguide, and a decoupling structure is provided in the lateral surface of the waveguide for decoupling light, which exits the waveguide via an exit region of the lateral surface along the light propagation direction, thereby overriding the total reflection condition.
POLICE VEHICLE EXTERIOR LIGHT CONTROL
Systems and methods are disclosed for a police vehicle exterior light control. An example disclosed police vehicle includes first beacons positioned on a chassis of the police vehicle, second beacons positioned on a lightbar of the police vehicle, and a plurality of spotlights on the lightbar. The example police vehicle also includes a light control unit that tracks a location of wearable nodes associated with a police officer. Additionally, the light control unit illuminates the area around the police officer using selected ones of the plurality of spotlights.
LIGHT EMITTING DEVICE
Provided is a light emitting device disposed along a transparent member. The light emitting device includes: an organic electroluminescence panel having a translucent substrate disposed to face the transparent member, a translucent anode disposed on the substrate, an organic material layer disposed on the anode, and a non-translucent cathode disposed on the organic material layer. The organic material layer and the cathode are formed in a form of stripes. The cathode is formed wider than the organic material layer.

The optical element includes an optical element body provided with a light incident surface and a light emergent surface; the optical element body is provided with a second reflective surface peripherally arranged along the light emergent surface; the second reflective surface and the light emergent surface form a cavity, and a light source is arranged in the cavity; the light incident surface is attached to a top of the light source; and along a diameter direction of the light emergent surface, the light emergent surface includes a first transparent surface, a frosted surface, and a second transparent surface, which are connected in sequence. The light distributing module includes: the above-mentioned optical element and a reflector; and along a direction away from the light emergent surface, one end of the reflector is connected with the light emergent surface.
VEHICLE EXTERIOR DOOR HANDLE SYSTEM WITH LIGHT MODULE
A vehicular lighted exterior door handle system includes a lighted exterior door handle assembly and a light module disposed at the door handle assembly. The light module includes at least three illumination sources linearly arranged at a circuit board and individually operable to emit light. With the door handle assembly mounted at a door of a vehicle, the individual illumination sources are operated responsive to a user input that is actuatable by a driver of the vehicle to activate a turn signal indicator system of the vehicle. With the door handle assembly mounted at the door of the vehicle, and when the illumination sources are operated to emit light responsive to actuation of the user input, an operation sequence of the individual illumination sources is varied between at least a first operation sequence and a second operation sequence based at least in part on movement of the vehicle.
