20230066763 · 2023-03-02 ·

A lamp module includes a light source unit that generates light; a light guide unit that guides the light incident on an incidence portion from the light source unit to be emitted to an emission portion; and an optical unit that transmits the light emitted from the light guide unit to allow a predetermined beam pattern to be formed. In particular, the optical unit includes a plurality of lenses disposed in a vehicle width direction, and the emission portion includes a plurality of emission surfaces disposed in the vehicle width direction to correspond to the plurality of lenses.

VEHICLE LIGHTING DEVICE

In order to ensure accuracy for positioning two molding members spaced from each other and an outer lens disposed in an opening between the two molding members, a vehicle lighting device includes: a first molding member; a second molding member that is formed separately from the first molding member and is spaced from the first molding member through an opening; and an outer lens, disposed in the opening, having a transmissive surface through which lamp light is transmitted from a depth side toward a front side. The first molding member and the second molding member each have a molding-side positioning portion configured to be positioned relative to the transmissive surface of the outer lens. The outer lens has a first lens-side positioning portion configured to be positioned relative to the first molding member and a second lens-side positioning portion configured to be positioned relative to the second molding member.

A light spreading lens, an automotive lighting system, and method of manufacturing a light spreading lens are described. The light spreading lens includes an outer surface. The outer surface is defined by a Boolean intersection of a first cylindrical lens overlaid with a second cylindrical lens. The first cylindrical lens is configured to distribute light along a first axis. The second cylindrical lens is configured to distribute light along a second axis.

MINI OR MICRO LED-BASED LIGHT MODULE CONFIGURED TO PERFORM PLURAL LIGHT FUNCTIONS SEAMLESSLY WITH DIFFERENT LIGHT GUIDES IN UNITARY ASSEMBLY

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.
